Air conditioning

Pinyin kōngtiáo

Interpretation

(1) [aircondition]: air conditioning is to adjust the house, engine room, cabin, The air temperature, humidity, cleanliness, air flow speed, etc. inside the carriage must meet certain requirements.

(2) [air-conditioner]: refers to the above device: air conditioner. Example: This room is already air-conditioned. [Edit this paragraph] Brief description of air conditioner Air conditioner is an air conditioner (room air conditioner), which is a unit used to provide processed air to a space area (usually closed). Its function is to adjust the temperature, humidity, cleanliness, air flow rate and other parameters of the air in the room (or enclosed space or area) to meet the requirements of human comfort or process. [Edit this paragraph] Working principle The compressor compresses the gaseous refrigerant into a high-temperature and high-pressure liquid refrigerant, and then sends it to the condenser (outdoor unit) for heat dissipation and becomes a normal-temperature and high-pressure liquid refrigerant, so the outdoor unit blows out hot air. .

Then it goes to the capillary tube and enters the evaporator (indoor unit). Since the space of the refrigerant suddenly increases after reaching the evaporator from the capillary tube and the pressure decreases, the liquid refrigerant will vaporize and become a gaseous low-temperature The refrigerant absorbs a large amount of heat, and the evaporator will become cold. The fan of the indoor unit blows the indoor air through the evaporator, so the indoor unit blows out cold air; the water vapor in the air evaporates when it encounters cold After the air conditioner is installed, it will condense into water droplets and flow out along the water pipes. This is why the air conditioner produces water.

Then the gaseous refrigerant returns to the compressor to continue compression and continue the cycle.

When heating, there is a component called a four-way valve, which causes the refrigerant to flow in the condenser and evaporator in the opposite direction to that during cooling. Therefore, when heating, cold air blows outside and the indoor unit It was blowing hot air.

In fact, it is based on the principles learned in junior high school physics of discharging heat when liquefying (changing from gas to liquid) and absorbing heat when vaporizing (changing from liquid to gas). [Edit this paragraph] The invention of air conditioning. Willis Havilland Carrier (translated as Carrier in some places), a British inventor known as the father of refrigeration, designed and installed the first air conditioning system in 1902. . A printer in New York, USA, discovered that temperature changes could cause paper deformation, causing colored ink imbalance. This air conditioning system was designed for him. Carrier's patent was registered in 1906.

On July 17, 1902, Carrier, a young man who had just graduated from Cornell University one year ago, invented the air conditioner while working at the Buffalo Forge Co. . But the original purpose of inventing the air conditioner was not to bring a comfortable living environment to people, but to serve some dead things.

It is said that one of the customers of Buffalo Company at that time was Schachter William Printing House in New York City. Due to changes in air temperature and humidity, its printing press caused the paper to expand and contract erratically, and the ink registration was inaccurate. , unable to produce clear color prints. So the Buffalo Company was turned to. Khalil thought that since he could use air passing through a coil filled with steam to keep him warm, why not use air passing through a coil filled with cold water to cool him down? Water in the air condenses on the coils, keeping the air in the factory cool and dry.

On July 17, 1902, the era of air conditioning began with the first use of air conditioners in this printing factory. Soon, other industries such as the textile industry, chemical industry, pharmaceutical industry, food and even the arms industry also greatly improved product quality due to the introduction of air conditioning. In 1907, the first exported air conditioner was purchased by a silk factory in Japan.

In 1915, Carrier founded a company that remains one of the largest air conditioning companies in the world. But in the 20 years since the invention of air conditioning, it has been machines, not people, that have been enjoyed. It wasn't until 1924 that a mall in Detroit, where many people fainted due to the hot weather, first installed three central air conditioners. This was a great success. The cool environment greatly increased people's desire to consume. Since then, air conditioning has It has become a powerful tool for businesses to attract customers. The era of air conditioners serving people has officially arrived.

But when it comes to popularizing air conditioning, it can only be achieved through movie theaters. Most Americans were first exposed to air conditioning in a movie theater.

Cinemas in the 1920s took advantage of air conditioning technology that promised to provide audiences with cool air, making air conditioning as engaging as the movies themselves, and summer replaced winter as the peak moviegoing season. Subsequently, a large number of year-round indoor entertainment venues such as casinos, indoor sports arenas and shopping malls emerged, all thanks to the advent of air conditioning. [Edit this paragraph] Functions of air conditioners 1. Cooling

In the design and manufacturing of air conditioners, the temperature is generally allowed to be controlled between 16 and 32°C. If the temperature setting is too low, on the one hand it will increase unnecessary power consumption, and on the other hand it will cause a large temperature difference between indoor and outdoor. People entering and exiting the room will not be able to quickly adapt to the temperature changes and will easily catch colds.

2. Dehumidification

The air conditioner is accompanied by dehumidification during the cooling process. The relative humidity of the environment that people feel comfortable should be around 40~60%. When the relative humidity is too high, such as above 90%, people still feel bad even if the temperature is within the comfortable range.

3. Warming up

Both heat pump type and electric heating type air conditioners have heating functions. The heating capacity gradually decreases as the outdoor ambient temperature decreases. If the temperature is -5°C, it can hardly meet the heating requirements.

4. Purify the air

The air contains a certain amount of harmful gases such as NH3, SO2, etc., as well as various odors such as sweat odor, body odor, and bathroom odor.

Air conditioner purification methods include: fresh air, filtration, adsorption and absorption using activated carbon or photocatalyst, etc.

A. Replace with fresh air: Use the fan system to discharge the indoor humid air outdoors, forming a certain degree of negative pressure indoors. Fresh air enters the room from the surrounding door and window gaps to improve indoor air quality.

B. Photocatalyst: It can be regenerated under the irradiation of light, and releases the adsorbed (collected) harmful substances such as ammonia, nicotine, acetic acid, hydrogen sulfide, etc., and can be reused.

5. Increase the concentration of negative ions in the air

The concentration of charged particles in the air will affect the comfort of the human body. Installing a negative ion generator on the air conditioner can increase the degree of negative ions in the air, making the environment more comfortable. It also has certain medical effects on lowering blood pressure and suppressing asthma. [Edit this paragraph] Development history In the 1960s and 1970s, rare drought weather occurred in the United States. In order to solve the problem of air conditioning cold and heat sources in drought and water shortage areas, the United States took the lead in developing an air-cooled chiller, which used air Heat dissipation replaces cooling towers, and its English name is: Air cool Chiller, referred to as Chiller!

In the history of air conditioning, the United States has developed and improved a central unit system with air ducts, and has received on-site Strong support from air conditioning equipment distributors and dealers who install and repair ducted unit air conditioning systems. WRAC is the simplest and cheapest system that can be easily purchased in retail stores and installed by yourself during the continuous high temperatures. Meanwhile, ductless SRACs and SPACs have been developed and improved in Japan since the 1970s under dynamics different from those in the U.S. market. Afterwards, equipment design and manufacturing technology was transferred to China in the 1990s, through partnerships with local companies including local manufacturers of major components such as compressors, heat exchangers, electric motors, precision valves and electronic controllers. conducted by a joint venture. In the 1990s, China also absorbed advanced high-tech technologies for larger air-conditioning equipment from other advanced countries and formed joint ventures with large companies, mostly in the United States. Today, China is a top country, with its major local factories and joint ventures manufacturing large quantities of SRAC and SPAC to meet the growing domestic market and export needs. Japan has been exporting SRAC and SPAC units to China, Europe and the Middle East in the past few years to establish new markets. However, China is now the largest exporter of air conditioners. The total number of WRAC, SRAC and SPAC units exported in 2001 reached 5 million units. It is expected that 7.5 or 8 million units will be exported in 2002, while Japan is losing its export status.

From January to October 2008, China's air conditioning industry enterprises achieved a cumulative total industrial output value of 143,283,146,000 yuan; a cumulative product sales revenue of 151,410,493 yuan; and a cumulative total profit of 5,165,862,000 yuan.

The historical evolution of the appearance of my country's household air-conditioning products

1. The first generation of grille panel household air conditioners

In 1988, the first domestic split wall-mounted The machine KF-19G1A was born in Huabao Air Conditioner Factory. At that time, Huabao gave it a very poetic name - Snow Lotus. The birth of Snow Lotus opened a new era in my country's household air conditioner industry. Since then, Chunlan has also had its own hang-up production line.

The air conditioners produced by Huabao and Chunlan dominated for nearly 10 years from the late 1980s to the mid-1990s. The air conditioners they produced were very similar in appearance: a flat, large rectangular structure. . At the same time, a large number of imported products had roughly the same appearance before the mid-1990s. Therefore, it was difficult to identify the brand of air conditioners at that time, especially hang-up units, without looking at the trademark.

In 1988, Huabao Air Conditioner Factory developed the first split wall-mounted machine KF-19GA, which was a typical representative of grille panel products

Until 1995, Chunlan’s KFR —22G is still the leading product in the on-hook market, which also shows that domestic air-conditioning products at that time were still dominated by grille panels.

The same is true for cabinet machines. Since Chunlan developed the new 70DS cabinet machine in 1987, many brands have only fine-tuned some details or color shades in the production of cabinet machines.

Second generation grille panel household air conditioners

As household air conditioners gradually become more popular, their appearance is also quietly changing. This change is first imported from The machine market is beginning to sprout.

In the 1980s, China’s air-conditioning market was dominated by imported machines. Even from 1991 to 1995, imported machines still played a decisive role. Imported machines played an enlightening role in the development of China’s household air-conditioning industry. The production of many domestic brands is to introduce accessories and assemble them. This enlightenment also includes changes in the appearance of the indoor units of my country's household air conditioners.

In the mid-1990s, a small indoor unit appeared in imported air conditioners represented by Mitsubishi Electric, Hitachi, Panasonic, etc. This indoor unit changed its previous image of being bulky and dignified. The appearance is exquisite and neat, integrating with the home environment, and is deeply favored by consumers. As many domestic air conditioning factories popularized the production of such products, the second generation grille panel air conditioners dominated the air conditioning market and are still popular today.

From the first generation grille panel to the second generation grille panel is a progress in the appearance of household air conditioner products. This progress is not only reflected in the smaller size and beautified appearance. It is also reflected in the change of the indoor unit evaporator folding type and the improvement of the air conditioner system capacity. It can also be seen from this aspect that the change of the evaporator folding pattern is a key factor in the transformation of the two generations of grille panels. In the late 1990s, many companies invested a lot of manpower and material resources in the research of folding evaporators. Midea also applied for a patent for multi-fold evaporators in 1998. Many of its products use four-fold evaporators, while Gree, another leading brand in the industry, generally uses five-fold evaporators.

However, there is no major change in the air inlet mode from the first-generation grille panel to the second-generation grille panel. The air circulation path is still used with front air inlet and outlet. Of course, this is also the fundamental reason why grille-type panels are grille-type panels. Its technical features determine its appearance.

3. The advent of the optical panel era

When you open the 2005 new product color pages of various domestic factories, a new atmosphere emerges. Compared with previous years when grille panels were the mainstream, most brands launched light panel series air-conditioning products in 2005, such as Gree's Tianli series, Haier's high-efficiency oxygen bar series, Midea's Q2 series and V series, etc.

This collective behavior of various manufacturers in the air-conditioning industry has pushed my country's household air-conditioning products into the era of light panels.

The glossy panel series of household air conditioner products did not appear for the first time in 2005. The first brand of domestic air conditioner manufacturers to launch glossy panel series products was TCL.

In 2001, TCL air conditioners launched its new "Xiao Fengxia" series of air conditioners. For the first time, this series of air conditioners promoted the smooth panel and large circulation air duct as selling points.

The so-called large circulation air path refers to designing the air inlet of the indoor unit at a certain position, using the upper air inlet and lower air outlet method to increase the air circulation radius and form a large circulation air path, thereby strengthening indoor air convection and speeding up the heat exchange speed. .

In 2001, TCL Air Conditioner launched the "Xiao Feng Xia" series, the earliest representative product of light panel air conditioners

The large circulation air duct is a technical feature of the "Xiao Feng Xia" series , is also an important selling point of optical panel products

TCL's move did not receive a positive response from the industry and market that year, but it provided a development idea for household air conditioner products. In the following years, some air conditioner factories successively launched their own series of light panel air conditioners. Light panel air conditioners from LG, Samsung, Sharp, Midea, Chunlan, Yongle and other factories were launched sporadically in 2003, and in 2004 This phenomenon intensified every year, and by 2005 it became a trend. Judging from the new products launched by various factories in 2006, air conditioners with light panels have become dominant.

Compared with grille panels, light panel products pay more attention to the fashion and modern appearance. The leap from grille panels to light panels is not only an improvement in appearance, but also a change in product technology. The top air inlet and bottom air outlet of the light panel cabinet machine has replaced the original front air inlet and bottom air outlet circulating air path, and the side air inlet or air inlet opening and closing design of the light panel cabinet machine has gradually become different from the original traditional bottom air inlet and top outlet. The air circulation path is completely consistent with the design trend of main cabinet products.

4. The sudden rise of color panels

In the domestic air-conditioning market, introducing color into the design of air-conditioning panels and forming a traditional style is a pioneering work of Korean brands Samsung and LG. In 2002, the colorful panels of Samsung's new air-conditioning cabinet "Style" series of the year made the entire air-conditioning industry shine. Especially under the "white" cover of other brands without exception, Samsung's color panel cabinets The machine is particularly eye-catching.

In the following years, both Samsung and LG launched new home air conditioners with color panels. Meanwhile, other factories began to follow suit. By 2005, most factories had color panel products on the market; moreover, the color types of panels began to become more colorful, and many of the color panel products are classics, such as Haier's color screen dual new style, Gree's Tianli, Zhigao's Huahaoyueyuan, TCL's Junlan series and Heidina series, etc.

In 2006, the factory became more bold and bold in the development and promotion of color panel products. Galanz even applied for a patent for color panel air conditioners; and judging from the new products now on the market, single white products Very few. Home air conditioners are changing in the opposite direction from traditional white appliances.

The technological development of household air conditioning products has always been controversial. The three major technological development trends of frequency conversion, energy saving and environmental protection lack the market foundation to support their large-scale breakthrough in the current industry environment. In other words, It is difficult for household air conditioning products to create new demands through revolutionary technological innovation. On the contrary, changes in product appearance brought about by fine-tuning of technology are becoming an irresistible trend, and the reason why this trend can become a reality is consistent with the changes in people's living environment and aesthetic concepts in the new era; Moreover, , for factories, the cost of changing the appearance of products is not very high. However, it needs to be reminded that from the perspective of the technological development trend of household air conditioners, changes in appearance are not the mainstream of technological development. It is just an improvement in technology. More importantly, in recent years, the quality problems of air conditioning products have become more and more serious. The more serious it is. [Edit this paragraph] Instructions for use: Residents consume a lot of electricity in summer, mostly due to the use of air conditioners. Energy saving of air conditioners can be said to be an important means of energy saving for home appliances. Experts suggest that during peak electricity consumption, if the air conditioner is set at the accustomed temperature, Increasing the temperature by 1℃ can save 10% of the power load; using the sleep function of the air conditioner can save 20% of the power. If the air-conditioning temperature of a 300-room hotel is increased by 1°C, the electricity problem of dozens of households will be solved. For every 1 kilowatt hour of electricity saved, 0.4 kilogram of standard coal, 4 liters of purified water, and 0.272 kilogram of carbon dust, 0.997 kilogram of carbon dioxide, and 0.03 kilogram of sulfur dioxide are saved. Not to mention saving electricity by starting with the "power-consuming" air conditioner, which not only saves energy, but also saves considerable money. Scientific experiments have proven that the indoor temperature that the human body feels comfortable is 24℃-28℃ in summer and 18℃-22℃ in winter.

When the relative air humidity is 50% and the temperature is 25°C, the human body feels most comfortable. You can refer to the following methods.

The first tip: Don’t blindly covet the low temperature of the air conditioner. Just set the air conditioner temperature appropriately, because when the air conditioner is cooling, increasing the set temperature by 2°C can save 20% of electricity. Experts say, For people who are sitting quietly or doing light labor, the acceptable indoor temperature is generally between 27℃-28℃, so at this time, you can set the air conditioner to sleep mode, which can also save electricity.

Second tip: Choose an air conditioner with moderate cooling power. An air conditioner with insufficient cooling power will not only fail to provide sufficient cooling effect, but also will shorten the service life of the air conditioner and increase the possibility of air conditioner failure due to long-term uninterrupted operation. So is it necessarily better to choose an air conditioner with greater cooling power? Not really. According to reports, if the cooling power of the air conditioner is too large, the thermostat of the air conditioner will switch on and off too frequently, resulting in increased wear and tear on the air conditioner compressor; at the same time, it will also cause an increase in the power consumption of the air conditioner.

Third tip: Close doors and windows when turning on the air conditioner. Do not open the door frequently in air-conditioned rooms to reduce the penetration of hot air. At the same time, for air conditioners and window air conditioners with ventilation function, if there is no odor in the room, the air door can be ventilated without opening the damper, which can save 5%-8% of energy. [Edit this paragraph] 5 steps for purchasing and installing air conditioners. 5 steps for purchasing and installing home central air conditioners

Step 1: Determine the host model

First of all, consider the area and orientation of the house to see if there is Large area glass windows are used to calculate the maximum simultaneous use factor of air conditioners. Generally speaking, in an ordinary home environment, the cooling capacity required for actual use is often not the combined cooling capacity of all rooms, but lower than the latter. The former only needs to reach about 60% to 70% of the latter. This saves investment and avoids unnecessary waste. The actual cooling capacity required in the room can be calculated by the following formula:

Actual cooling area = building area × house practicality rate × 65% (excluding non-cooling areas such as kitchens and bathrooms)

Actual required cooling capacity = actual cooling area A room or hall only needs one indoor unit or air outlet. If the living room is large or rectangular, you can add an additional indoor unit or air outlet. About one horse is required for every 12 square meters.

Step 3: Determine the layout of the air conditioner:

1. The location of the host should have good ventilation and heat dissipation to facilitate maintenance and repair. At the same time, the location should be as hidden as possible to avoid affecting the appearance of the house and noise impact. Indoor;

2. The location of the indoor unit should match the indoor decoration layout. It is usually hidden in the ceiling or on the top of a high cabinet. Generally, indoor units are ultra-thin and only require a height of about 25 centimeters to be placed. When installing, pay attention to good return air to circulate indoor air to ensure air conditioning effect and air quality.

Maintenance and cleaning of air conditioners are the main keys to air conditioning maintenance. It is beneficial to improve the cooling effect, shorten the cooling time, and save energy of the air conditioner. Extending the service life of air conditioners is an important part of rational use of air conditioners and strengthening standardized management. In the past, air conditioner users did not pay enough attention to the maintenance and cleaning of air conditioners. Now we should strengthen work in this field and promote the development of the air conditioning industry.

Maintenance before starting up

Usually, household air conditioners are shut down and deactivated in September, and are not turned on until May or June of the following year, and are deactivated for more than half a year. Therefore, before starting the air conditioner, a comprehensive "diagnosis" must be done to check whether there is any "fault" in the air conditioning equipment. Based on the inspection results, under the guidance of professional technicians, maintenance and cleaning work must be carried out. This maintenance and cleaning must be in place. Including the casing, body, and filter of the outdoor unit and indoor unit, and then start a trial run to observe the cooling speed and effect.

Maintenance during the startup process

After the air conditioner is turned on, the environmental conditions, climate conditions, startup hours, surrounding dust, air cleanliness, whether the room is clean and many other factors determine the startup process of the air conditioner. maintenance times. The environmental conditions are not good, the weather is hot, the air conditioner is old, the air conditioner is turned on for a long time, and the number of maintenance times during the startup process of the air conditioner increases, usually once every one and a half months. If the environmental conditions are good, the air conditioner is relatively new, there is less dust in the air, the air conditioner is turned on reasonably, and it is used alternately with the electric fan, the maintenance cycle can be appropriately extended, and the maintenance cycle can be 1-2 times from the air conditioner on to the air conditioner shutdown. Maintenance should be carried out seriously and carefully, leaving no dead ends. Comply with specifications, improve refrigeration speed and refrigeration effect, and achieve energy saving, freshness and comfort.

Maintenance after shutdown

When the weather gets warmer, the air conditioner is turned on, and when the weather gets cooler, the air conditioner is turned off. This is a year-round rule. Note that the outdoor unit and indoor unit should be thoroughly and carefully inspected before shutting down the air conditioner. Maintenance, maintenance, and cleaning must be carried out step by step and cannot be disconnected. Leak-prone parts should be tightened and inspected strictly. After completing the above steps, put on the air conditioner cover to prevent dust pollution, dripping and water ingress of the air conditioner. Keep it clean and ready for reuse next year. This will ensure cleanliness, save energy, and extend the life of your air conditioning equipment. High-quality split machines and cabinet machines of well-known brands must be protected to give full play to their energy-saving effects.

General air conditioning maintenance and maintenance

1. Remove debris from the vents to ensure normal ventilation. Observe whether the outdoor rack is loose, and clean whether there is any foreign matter in the outdoor ventilation grille. Also, keep vents clear and unobstructed.

2. Clean the surface of indoor and outdoor heat exchangers to improve the efficiency of the heat exchanger. When cleaning the indoor heat exchanger, you should carefully remove the panel, scrub it with a soft rag, and use a small brush to gently scrub the heat exchanger of the indoor unit. This will achieve the purpose of removing dust and harmful accumulations that can breed germs. However, please note that since the heat sink is made of very thin aluminum material, it is easy to deform after being stressed, so be careful when brushing.

3. Clean the dust on the filter screen.

When cleaning the filter, first cut off the power, then open the air inlet grille; take out the filter, clean the filter with water or a vacuum cleaner, the water temperature should not exceed 40 degrees, clean with a hot wet cloth or neutral detergent, and then wipe with a dry cloth Do not use pesticides or other chemical detergents to clean the filter.

4. Clean the dirt and accumulation in the drainage part. The drainage part is prone to deposits of dirt and must be thoroughly disinfected regularly to ensure smooth drainage and prevent bacterial growth.

5. Check others. Including power supply lines, plug boards, switches; check the condition of consumable parts, such as air guide rotating plates, sterilization and dehumidification, photocatalysts, etc., to ensure that the air conditioner is in good condition and without abnormalities.

Air conditioning maintenance during special periods

During the moderate temperature seasons from March to May and September to November, people generally leave the air conditioner in a non-working state. In seasons when the air conditioner is not in use, you should first cut off the power supply to the air conditioner, but it is best to keep it on once a month to prevent the lubricating oil in the machine from condensing due to long-term non-use. At the same time, in order to ensure the long-term high-speed operation of the air conditioner and the extension of its use mission, you must also pay attention to the proper maintenance of the air conditioner when suspending and starting to use the air conditioner.

1. After the use season is over. Before suspending the use of the air conditioner, set the air conditioner to the air supply state on a sunny day and turn it on for about half a day to make the inside of the air conditioner completely dry; at the same time, the dust filter, indoor unit, and outdoor unit should be cleaned.

2. Before the use season begins. Check whether there are any obstacles in the air inlet and outlet of the indoor and outdoor units to avoid reducing the working efficiency of the air conditioner; install a dust filter to avoid damage to the machine or cause malfunction due to dust entering the inside of the machine; use a dry cloth to clean the remote control. Do not use glass cleaners or chemical-containing cloths, and install two new batteries of the same model after cleaning. [Edit this paragraph] Cleaning method The cleaning of the air conditioner should include three parts. The first is the shell and exposed parts of the air conditioner, which are easily contaminated parts; the second is the cleaning of the filter, which is the most important part of the core; the third is the condenser and evaporator. The air conditioner part is relatively rare. It is combined with maintenance. It is equivalent to the cleaning of a small system. It is a relatively large "surgery". It often appears on old air conditioners or "special price machines" and "inferior air conditioners". This type of air conditioners is quite large. Some parts have no cleaning or repair value and will not be detailed.

Cleaning the outer casing and corresponding parts of the air conditioner is simple. Just add a little soap powder and detergent to clean water, or a special air conditioner cleaning fluid to clean a considerable part of the air conditioner, which meets the cleaning operation requirements. . As for the key part of cleaning the household air conditioner, it is the filter. First, open the indoor cover of the air conditioner, take out the filter, brush it with a clean filter brush to clean most of the dirt attached to the filter, and then soak it Soak the filter in a mixture containing special air conditioner cleaning fluid or homemade cleaning fluid or detergent and soap powder for 10-20 minutes, depending on how dirty the filter is. After soaking, gently brush the filter with a bottle brush. Make each filter hole clear and transparent, with no trace of dirt or blockage, then wipe it dry with a special cleaning cloth and check it is intact. After installing the filter into the body, check whether it is operating normally. If it is normal, the order can be signed and accepted, and the cleaning work is completed. Cleaning household air conditioners is beneficial to improve refrigeration efficiency; it is beneficial to improve refrigeration effects, it is beneficial to extend the life of household air conditioner equipment, it is beneficial to improve energy saving effects, it is beneficial to users' health, and the effect is healthier and more ideal than "healthy air conditioners".

Many years of practice in the air conditioning industry have proven that it is best to clean air conditioners 2-3 times a year. It is usually more reasonable to clean the air conditioner once before it is turned on, once during the period when the air conditioner is turned on, and once when the air conditioner is turned off. Sometimes when the air conditioner is shut down, after a major cleaning process such as maintenance, maintenance and cleaning, the air conditioner is put on the hood. When it is turned on next year, it will be relatively clean and the filter will be clean. At this time, the cleaning before the air conditioner is turned on is eliminated for one year. After cleaning twice, the effect is very good, saving labor and expenses, reducing operating costs, and not affecting the refrigeration effect. [Edit this paragraph] Precautions Precautions for the use of household air conditioners:

1. Be sure to clean the dust on the air conditioner filter before use.

2. Soak and disinfect the filter with disinfectant.

3. If possible, it is best to use a vacuum cleaner to remove dust from the indoor fan before use.

4. Open the windows for a quarter of an hour every day when you turn on the air conditioner. When using it for the first time, you should ventilate it for more time to allow the bacteria, mold and mites accumulated in the air conditioner to be dispersed as much as possible.

5. Disinfect air conditioning filters frequently.

6. Do not leave the air conditioner on indoors for too long. It is best to open windows frequently for ventilation to reduce the concentration of toxic gases in the room and inject fresh air regularly.

7. Pay attention to adjusting the indoor and outdoor temperature difference, which should generally not exceed 8 to 10 degrees Celsius.

8. Smoking is strictly prohibited in the room.

9. Be careful not to spray pesticides or volatile liquids on the air conditioner when it is running to avoid leakage of electricity and cause an accident.
