Discussion on water source heat pump refrigeration heating technology
2. The prospective heat pump technology in the United States as of 1985, a total of 14,000 installations nationwide, has installed 400,000 units. In 1998, heat pump air conditioners accounted for 19% of commercial buildings in the United States, of which 30% were new buildings. This shows how an inexpensive, environmentally friendly, low-energy product is so popular. In China, heat pump technology is in the ascendant and is developing rapidly. There are hundreds of heat pump units in operation throughout the country. According to China's national conditions, with a large population and limited energy, heat pump technology is in line with the national sustainable development strategy, so the development prospects are broad.
3. advantage
1)Environmental protection and energy saving Use underground shallow water as a source of cold and heat, eliminating the pollution caused by coal, gas and fuel; eliminating the boiler room and cooling tower, saving land, and avoiding the noise and mold of the cooling tower Pollution, in line with environmental requirements.
2) The initial investment is only 1/2~2/3 of other central air conditioners (the cost of boiler room and cooling tower is saved, and the cost of drilling is increased).
3) Energy-saving economy 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 1/2~1/3 compared with the conventional method.
4) The operation of the reliable unit is stable and almost independent of weather and ambient temperature. The main components of the unit are few, the maintenance is simple, and the operating life of the main engine can reach more than 15 years.
5) Flexible and safe use of water source heat pump to heat buildings in winter, to cool buildings in summer, and to supply domestic hot water throughout the year, truly "one machine and two use", improving the utilization rate of equipment. The unit can be flexibly placed anywhere to save space. There are also many options at the end of the system. There are no health and safety hazards such as coal storage and oil storage tanks. When considering air conditioning solutions, the following points should be taken into account:
(1) With a small investment of zui, we get good quality products;
(2) The performance is reliable, can withstand the practice test, is not easy to malfunction, and the maintenance cost is low;
(3) The use is long and easy to handle.
4. Conclusion It goes without saying that the many advantages of the heat pump system will make it the first user.
