Central air-conditioning water machines are widely used in some industrial fields. Central air-conditioning water machines are more energy-saving, more convenient, and save trouble and effort. The appearance of central air-conditioning water machines is relatively diverse. When we choose central air-conditioning water machines, the most important thing we pay attention to is the brand of the product. So let’s introduce to you the brands on the market that are worthy of consumers’ trust and have relatively reliable product quality. What are the top ten brands?

Recommended brands of central air-conditioning water machines

However, its equipment is large and the internal unit takes up a large space, so it is generally suitable for villas.

6. Mitsubishi Electric (Mitsubishi Electric and Mitsubishi Heavy Industries are both Mitsubishi brands, but they are very different in central air conditioning technology and market share. Mitsubishi Electric is assembled and produced in Shanghai). Mitsubishi Electric controls air conditioning. The core compressor technology has a beautiful design, but the noise of the internal unit is slightly greater than that of Hitachi and other central air conditioner internal units.

7. Gree (high-tech enterprise, 50 Asian companies, Chinese well-known trademark, Chinese famous brand, China's top 100 listed companies, Zhuhai Gree Electric Co., Ltd.), Gree is the industry leader in the field of ordinary split air conditioners The leader is slowly advancing the market in the field of central air conditioning. At present, the core compressor technology of domestic air conditioners is still in its initial stage of development.

8. Midea (Top Ten Brands of Central Air Conditioning, Midea Group’s Commitment, Professional Air Energy Central Hot Water, Central Air Conditioning, Guangdong Midea Commercial Air Conditioning Equipment Co., Ltd.), Midea and Gree are the leading brands in the entire air conditioning field Keep about the same pace.

Haier (a well-known trademark in China, a world-class home appliance brand, one of China's top 500 companies, the world's No. 1 white goods brand, one of China's most valuable brands, Haier Group Company), Haier air conditioners are small in size. Can be controlled directly by remote mobile phone.

10. LG (a famous Korean brand)’s control systems are all products with independent intellectual property rights, but other components are imported from well-known manufacturers. The appearance is compact and beautiful, and the product performance is stable and reliable.

The difference between central air-conditioning water machine and fluorine machine:

What are central air-conditioning water machine and fluorine machine:

Central air-conditioning water machine is what people often say Cold (hot) water unit, all indoor loads are borne by the hot and cold water unit. The fan coil unit in each room is connected to the hot and cold water unit through pipes, and relies on the hot and cold water provided to provide cooling and heating to the room. The water system has flexible layout, good independent adjustment and very high comfort, and can meet the needs of complex room types for dispersed use and independent operation of each room.

The central air-conditioning fluorine machine is what people often call a variable frequency one-to-multiple unit. It is a refrigerant-type air-conditioning system that uses a conveying refrigeration process. It can adjust the temperature of multiple rooms at the same time; in addition, the variable frequency compressor of the fluorine system outdoor unit can automatically adjust the working status of the compressor according to changes in indoor cooling and heating loads to meet the requirements of indoor cooling and heating loads, with accurate temperature control. It also saves electricity.

Comfort comparison:

The cooling (heat) carrier of the water machine is water, and its wind is very gentle, comparable to the spring breeze blowing on the face, very comfortable; and the water machine does not Taking away moisture from the indoor air and keeping the air moist, making people feel warm and pleasant. Comfort is the biggest highlight of the central air-conditioning water machine.

Fluorine machines use Freon or the new refrigerant R410A, which is a refrigerant. When used, it will take away indoor moisture, making the air drier and slightly less comfortable. However, brands such as Mitsubishi Heavy Industries, Samsung, and Daikin The refrigeration system used by major brands is R410A, which has a gentler air output and is much more comfortable than a split unit.

Energy-saving comparison:

Although the water machine uses fixed-frequency technology, the heat capacity of water is relatively large. The greater the usage rate, the more energy-saving it is. It is suitable for use in large-area houses.

The fluorine machine uses variable frequency technology, which has the advantages of high control accuracy, high efficiency and energy saving. Especially for users with small houses, its energy saving advantages are more prominent.

Reliability comparison:

The water machine adopts a dual-circuit design and multiple compressors. Even if one compressor circuit fails, it can still continue to work. Reliable scroll compressor, unit Long operating life and high reliability.

The fluorine machine has only one variable frequency compressor, and the controls of the outdoor unit and indoor unit are all connected. Once a certain unit fails, the entire system cannot be used.

Cooling heat speed:

Water has a larger heat capacity and is slower to heat up and cool down, so the cooling heat speed is not as fast as a fluorine machine.

The fluorine machine cools immediately when it is turned on, and it is very fast. It is very suitable for white-collar workers with a fast pace of urban life.

Heating effect in winter:

Water has strong adaptability. The heating range of the water machine can be -10℃? In addition, a wall-mounted boiler can be added to the water system for auxiliary heating. The heating effect in winter Better.

The fluorine machine has the disadvantage that traditional split machines have poor heating effect in winter. The heating effect is poor below -5℃. It is generally recommended to install floor heating or radiators for heating in winter.

When you buy a central air-conditioning water machine, you must look for the brand. In addition, because there are many fake and shoddy products on the market, in case you buy products with substandard quality, it is best to Purchase products in physical stores or official websites. In addition, because there are many models of central air-conditioning water machines and their prices are also different, it is best for everyone to understand all aspects of the product’s performance in advance to ensure that you are buying the product you want. Suitable for use and at the same time good quality and affordable.
