The development of air source heat pump
The first generation: gas water heaters:
1. The effluent temperature and water pressure are greatly affected by climatic conditions, and it is not easy to adjust the water temperature.
2. High combustion energy consumption and a large amount of toxic waste gas are emitted, and the service life is low.
Second generation: electric water heater:
1. Mainly due to high energy consumption, it is easy to leak electricity and hurt people, and the water storage capacity is insufficient.
2, the water temperature is too high, the bladder scale is serious and the service life is short.
Third generation: solar water heaters:
1. In theory, it is the most energy-efficient, but considering the actual situation, the actual environment will often rain and cloudy, and the northern winter needs to be supplemented with electricity. It is quite a safety hazard for electric water heaters.
2. Because the general solar energy is the open system, the water pressure of the hot water is completely determined by the height difference.
3. The vacuum tube used in general solar energy is extremely easy to be broken and repaired, and the service life is low.
Fourth generation: air energy heat pump
In view of the high cost and high cost of the air energy heat pump, Finney has made unremitting efforts to develop an air energy heat pump in 2005. It works by absorbing the heat from the air (via refrigerant/refrigerant), releasing it into the water, circulating it to heat the water, and releasing the low-temperature air that loses a lot of energy to the kitchen or other places where it needs to be cooled, for kitchen or other Cooling needs. While the air loses energy and lowers the temperature, a large amount of water vapor is condensed, so that the released cold air humidity is greatly reduced, which is equivalent to having a dehumidifying effect. Therefore, the product integrates energy-saving central hot water, kitchen (toilet) refrigeration and partial dehumidification functions, greatly improving the cost performance and performance of the product. Providing conditions for more wealthy families to enjoy a high quality of life. It is understood that the working temperature of the air source heat pump is minus 10 to 40 degrees Celsius, while Hunan is a subtropical monsoon humid climate with an annual average temperature between 16 and 18 degrees Celsius. It is very suitable to use an air source heat pump central hot water unit. The use of this technology can effectively save energy, and its operating cost is only 1/4 of that of electric water heaters. For example, according to the existing electricity price and oil price, the same hot water is burned, and its operating cost is only 1/2 of that of the oil-fired boiler.
