Water source heat pump air conditioning system is energy efficiency ratio (COP) maximum cooling and heating mode, theoretical calculations can be reached 7, the actual operation of 4 to 6.Water source heat pump units available water temperature in winter is 12 ~ 22 ℃, water temperature than the ambient air temperature is high, so the heat pump cycle of evaporation temperature rises, energy efficiency is also improved. The summer water temperature is 18 ~ 35 ℃, water temperature than the ambient air temperature is low, so the refrigeration condensing temperature decreases, so the cooling effect is better than air-cooled and the cooling tower to improve plant operation efficiency. Water source heat pump's power consumption 1kW.h, the user can get 4.3 ~ 5.0kW.h 5.4 ~ 6.2kW.h heat or cold energy. Compared with air source heat pump, the operating efficiency of 20 to 60% higher, the operating cost of only 40 regular central air-conditioning to 60%.Water source heat pump uses the Earth's water resources as the storage of solar energy and heat sources, the energy conversion of heating and air conditioning systems. One can use water, including groundwater or river, the surface part of the rivers and lakes, and oceans. Surface soil and water is not only a huge solar collector, collecting 47% of the solar radiation energy, than the human annual use of energy, 500 times more (the ground water through the soil indirect sun's radiant energy), and is a great dynamic energy balance system, the surface of the soil and natural water bodies to receive and maintain the energy balance of the relative divergence. This allows the use of storage in which virtually unlimited solar energy or geothermal energy possible. Therefore, water source heat pump is clean use of a renewable energy technology.

To surface water as a heat source, its release heat or absorb heat, do not consume water, not its cause pollution; eliminating the boiler room and its subsidiary coal yards, oil storage rooms, cooling towers and other facilities, large size room area conventional air conditioning system, saving construction space is also conducive to building beautiful.Water source heat pump in heating eliminates the need for coal, gas, oil boiler system, however, no combustion process, to avoid the smoke, sewage and other pollution; cooling while eliminating the need for cooling towers, cooling towers to avoid the noise, mold contamination and water consumption. Therefore, water source heat pump unit operating without any pollution, no burning, no smoke, no waste, wastewater, waste gas and dust, no urban heat island effect, very friendly to the environment, is an ideal green environmental protection product.Water source heat pump heating system, air conditioning, but also for domestic hot water, use of a machine, a system can replace the original boiler plus air-conditioning of the two devices or systems. Especially for simultaneously heating and cooling requirements of buildings, water source heat pump has obvious advantages. Not only saves a lot of energy, and uses a set of equipment can meet the requirements of heating and cooling, reducing initial equipment investment. The total investment amounted to only 60% of the traditional air-conditioning system, and easy to install, installation less than traditional air conditioning systems, installation time is short, change the installation is also easy.Water source heat pump can be used in hotels, shopping malls, office buildings, schools and other buildings, a small water source heat pump is more suitable for villas, residential heating, cooling.

Water temperature is relatively stable throughout the year, far less than its range of fluctuation of air changes in water temperature more constant, which makes the heat pump more reliable, stable, and also to ensure the system's efficiency and economy;-wide computer control, automatic high. Because the system is simple, parts unit less stable and therefore low maintenance costs, long service life.Country attaches great importance to the development and utilization of renewable energy, "China Renewable Energy Law" was January 1, 2006 shall come into operation; the same time, "Long-term Scientific and Technological Development Plan", again to develop and large-scale application of new energy and renewable energy as a priority the development of energy sector themes. National legislation and development strategies from the height of the development and application of renewable energy to be strongly promoted.Recently, the State Ministry of Finance, Ministry of Construction, issued a document "on the promotion of renewable energy in building applications opinions" and "renewable energy management of special funds for construction applications Interim Measures," clearly states that "Eleventh Five-Year" period, renewable energy applications area ratio of total new building area more than 25% by 2020, renewable energy applications will occupy the new building area of ??more than 50% ratio, which is the development of water source heat pump provides a good environment and a strong impetus.
