Eight characteristics of central water heater:
1, safety Because it is not directly heated by electric heating elements, it eliminates the potential safety hazard of electric leakage compared with electric water heaters; Compared with gas water heaters, there are no potential safety hazards such as gas leakage and carbon monoxide poisoning, and the safety performance is better.
2. Comfortable domestic central energy-saving water heater is regenerative, which automatically starts the heating function according to the temperature in the water tank, and the hot water supply is sufficient for 24 hours. Therefore, there will be no problem that multiple faucets can't use hot water at the same time like gas water heaters, and there will be no problem that the capacity of electric water heaters is small and many people need to wait for a bath. That is, it can be heated immediately, with large water output and stable outlet temperature, meeting all your expectations for hot water.
3, save money because its power consumption is only a quarter of the same amount of electric water heater, which is equivalent to using the same amount of hot water, using a household central energy-saving water heater, and the electricity bill is only a quarter of that of electric heating. Based on a family of four, the normal hot water consumption is about 200L/ day, the electric water heater is about 4 yuan/day, and the domestic central energy-saving water heater only needs about 1 yuan/day, which can save about 1 ten thousand yuan a year.
4, kitchen refrigeration This is the biggest advantage, ordinary water heaters (such as electric heating, gas water heaters, solar water heaters, etc. ) it is completely unnecessary to have a cooling function. If the kitchen needs extra cooling function, you need to buy kitchen air conditioner. Because there is oil smoke in the kitchen, it is a special environment, so the kitchen air conditioner is different from ordinary air conditioner and the price is much more expensive. (Generally, the price is more than 4,000 yuan)
5. Green gas water heater heats hot water by burning combustible gas, and at the same time emits a lot of harmful waste gas such as carbon dioxide and sulfur dioxide. The domestic central energy-saving water heater only transfers the heat in the surrounding air to the water, with zero emission and little impact on the environment. It is a real environment-friendly water heater.
6. Today, low-carbon fashion can reduce emissions, which has become the general trend. Energy saving and emission reduction is the most fashionable way of life. As mentioned above, the domestic central energy-saving water heater uses the inverse Carnot principle to transfer the energy in the air to the water instead of directly heating it with electric heating elements, so its energy efficiency can reach four times that of electric water heaters, that is, heating the same amount of hot water, and the power consumption is equivalent to one quarter of that of electric water heaters, which greatly saves the power consumption. 70% of China's electricity is generated by burning coal in thermal power plants. Saving electricity means reducing carbon emissions.
7. The intelligent control unit is controlled by a microcomputer to run automatically, and automatically starts and stops according to the water temperature of the water tank and the user's water consumption, without special personnel on duty.
8. Use durable world-renowned spare parts. The main engine adopts famous compressor and five-fold antirust technology. The shell is made of corrosion-resistant ultra-thick coated steel plate or stainless steel plate. The equipment has stable performance and its service life can reach 15 years.
Working principle of central water heater
A complete domestic central energy-saving water heater consists of two main parts: the water tank part and the hot water heating part. But in fact, these two parts are closely related and inseparable, and must work at the same time. Its internal structure is mainly composed of four core components: compressor, condenser, expansion valve and evaporator. The working flow is as follows: the compressor compresses the low-pressure refrigerant flowing back and turns it into high-temperature and high-pressure gas to be discharged. The refrigerant gas with high temperature and high pressure flows through the copper tube wound outside the water tank, and the heat is conducted into the water tank through the copper tube. The cooled refrigerant becomes liquid under the continuous action of pressure and enters the evaporator after passing through the expansion valve. Because of the sudden drop of evaporator pressure, liquid refrigerant quickly evaporates into gas and absorbs a lot of heat. At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, the energy in the air is absorbed by the evaporator, and the air temperature drops rapidly, turning into cold air and being discharged into the kitchen. Then the refrigerant that has absorbed certain energy flows back to the compressor and enters the next cycle. As can be seen from the above working principle, the working principle of domestic central energy-saving water heater is similar to that of air conditioner, and the inverse Carnot principle is applied. By absorbing a lot of low-temperature heat energy in the air, it is compressed by the compressor and turned into high-temperature heat energy, which is transmitted to the water tank to heat water. The whole process is a process of energy transfer (from air to water), not a process of energy conversion. Hot water is either heated by electric heating elements or heated by burning combustible gas.
Now, after Bian Xiao's introduction, everyone should have a general understanding of the brand and working principle of the central water heater! Compared with ordinary water heaters, the advantages of central water heaters are very obvious. This kind of water heater has large capacity, stable temperature and 24-hour hot water. Now this kind of water heater is widely used, and it is used in various hotels, guesthouses, villas and other places, so it has a wide range of uses.
