Discussion on Water Source Heat Pump Refrigeration Heating Technology

1. Heat Pump Principle The heat pump unit heats by heating the heat released by the condenser in the air conditioning system and absorbs heat from the low temperature energy sources in the surrounding environment (river, lake, industrial and domestic sewage, groundwater, soil, etc.) Then released to the required area, to achieve the purpose of heating. With the use of refrigerator, a machine cold heating, energy saving and environmental protection, but also economical and practical.

2. Foreground heat pump technology in the United States as of 1985, the national installation of a total of 14000 units, has so far installed 400000 units. In 1998 heat pump air conditioning accounted for 19% of commercial buildings in the United States, of which about 30% of new construction. This shows that a cheap environmentally friendly low-energy products is how much popular. In China, heat pump technology is in the ascendant and is rapidly developing. There are already several hundred heat pump units in operation in the country. According to China's national conditions, a large population, limited energy, heat pump technology in line with national sustainable development strategy, so the development of broad prospects.

1) Environmental Protection and Energy Saving Utilize the shallow water in the underground to make cold and heat sources, eliminating the pollution caused by coal, gas and fuel; eliminating the need for boiler rooms and cooling towers to save land area and avoiding the cooling tower noise and mold Pollution, in line with environmental requirements.

2) The initial investment is only 1/2 ~ 2/3 less than other central air-conditioners (eliminating the cost of boiler room and cooling tower and increasing drilling costs).

3) Energy-saving Economical energy utilization rate is increased. When 1KW of electric energy is input, the energy of cooling or heating of 4.4KW-6KW can be obtained, and the operating cost can be saved by 1/2 to 1/3 of that of the conventional mode.

4) Reliable operation The operation of the unit is stable and hardly affected by the weather and the ambient temperature. The main components of the unit less maintenance is simple, the host operating life of up to 15 years.

5) Flexible and safe use of water source heat pump Heating to the building in winter, cooling to the building in summer, and domestic hot water supply throughout the year, truly "one machine with dual" and improve the utilization of equipment. Unit can be flexibly placed anywhere, saving space. There are many options available at the end of the system. No coal storage, storage tanks and other health and safety hazards. In considering the air conditioning program, the following points should be paid attention to:

(1) With the least investment, get the best quality products;

(2) reliable performance, stand the test of practice, not easy to fail, low maintenance costs;

(3) make use of long, easy to control.

4. Conclusion It goes without saying that the many advantages of heat pump systems make them the best first to users.
