"Heat pump" is a reference of the term "pump" is derived. In the natural environment, Going with the flow, heat transfer to the low position. Pump to pump water from the lower to the height advantage. The heat pump can be low level heat energy "pumping" (exchange of passes) to provide access to high-temperature place. In our country, "HVAC terminology standards (GB50155-92)" in the "heat pump" explained that "to achieve the evaporator and the condenser function of converting the refrigerator"; in the "New International Dictionary refrigeration (New International Dictionary of Refrigeration ) "in the" heat pump "explained that" the heat released by the condenser to heat the cooling system. " Can be seen, the heat pump is essentially the same with the refrigerator, just in different operating conditions. Its working principle is, by power driven compressor, the working fluid (eg, R22) recurring cycle of movement during the physical phase transition, respectively, in the evaporator absorbs heat in the gasification, liquefaction in the condenser heat, the heat exchange constantly delivery, and through the valve to switch the unit to achieve heating (or cooling) function. In this process, the heat pump compressor requires a certain quantity of high power drives, the evaporator heat absorption is low, but the heat output of the high heat energy is available in quantity is its high consumption of energy and the the sum of absorption of low energy. Heat output power to input power ratio as heat pump coefficient of performance, that is, the value of COP (Coefficient of Performance). There are many heat pump to heat water as heat source and water source heat pump is called the medium heat. Water source heat pump coefficient of performance (ie, COP) higher than theair source heat pump, system performance and stability.Water source heat pump project is a systematic project, generally by the water system, water source heat pump system and the end of the room cooling system consists of three parts. Among them, the water system including water, water structures, pipe network and water treatment equipment.Water system, water, water temperature, water quality and supply stability effects of water source heat pump system is running an important factor.

Water source heat pump applications, the principles of the water system requirements are: adequate water, moderate temperature, the water is suitable, water stability. Specifically, the source of water, should be sufficient enough to meet the heating load or cooling the user load. Such as water shortage, the unit's heating capacity and cooling capacity will be reduced, reaching less than user requirements. Water temperature should be moderate, the conditions required for plant operation. For example, Tongfang GHP-type water source heat pump heating system operating conditions, the water temperature should be 12-22 ℃; in the refrigeration operating conditions, the water temperature should be 18-30 ℃. Water quality, should be suitable for the system unit, piping and valves of the material, and will not cause serious corrosion damage. Water supply water system to ensure higher rates of long-term reliability of water supply capabilities, to ensure the long-term water source heat pump central air conditioning system and stable operation.
