We know that energy is the material basis for the existence and development of human society and the guarantee for human survival. The development of human society and the utilization of energy are inseparable. Among them, water source heat pump heating is one of the leading topics in the International Air Conditioning and Refrigeration Industry. It is the main form of renewable energy utilization such as solar energy and geothermal energy, and it is also a promising energy-saving and environment-friendly device and system. The working principle of water source heat pump is that the shallow water source on the Earth's surface absorbs the radiant energy of the sun entering the Earth, and the temperature of these water sources is generally very stable. The working principle of the water source heat pump unit is to transfer the heat in the building to the water source in summer. Due to the low temperature of the water source, the heat can be efficiently removed, while in winter, the energy is extracted from the water source, the heat pump principle uses air or water as refrigerant to raise the temperature and send it to the building. Usually, the water source heat pump consumes 1kW of the energy, and the user can get more than 4kW of the heat or cold. Water source heat pump uses water as heat source and cooling medium in both heating and cooling processes, I . e. switching working medium circuits to realize heating and cooling operation. Water, as the medium for heat pump heating and cooling processes, can be used if the following two conditions are met- First, the temperature of water is 7 °c ~ Between 30℃, the second is sufficient water. SOURCE water can be various industrial waste water, domestic water, seawater, rivers, river water, etc. , and even various industrial waste heat. Significant advantages of water source heat pump heating: 1. Environmental protection benefits are remarkable. Water source heat pump is a heating and air conditioning system that uses surface water as a cold and heat source for energy conversion. When heating, the boiler room system such as coal burning, gas and natural oil is omitted, and there is no combustion process, thus avoiding pollution such as smoke exhaust and sewage discharge; Cooling water tower is omitted during cooling, thus avoiding noise, mold pollution and water consumption of cooling tower. Therefore, water source heat pump uses a clean and renewable energy technology. The available water temperature of the high-efficiency water source heat pump unit is 12 ~ in winter ~ At 22℃, the water body temperature is higher than the ambient air temperature, so the evaporation temperature of the heat pump cycle increases and the energy efficiency ratio also increases. And the summer water body is 18 ~ At 35℃, the water body temperature is lower than the ambient air temperature, so the condensation temperature of refrigeration is reduced, making the cooling effect better than that of air-cooled and cooling tower types, and the unit efficiency is improved. According to EPA estimates, a well-designed and installed water source heat pump can save users by 30 ~ on average ~ 40% of the operating cost of heating, refrigeration and air conditioning. 2. The electric energy used by the energy-saving water source heat pump is itself a clean energy source, but when generating electricity, it consumes primary energy and leads to the emission of pollutants and carbon dioxide greenhouse gases. Compared with air source heat pump, a well-designed water source heat pump unit is equivalent to reducing power consumption by more than 30%, and compared with electric heating, it is equivalent to reducing power consumption by more than 70%. Therefore, while saving energy, the water source heat pump also reduces and reduces the pollution emissions and greenhouse effect generated in the process of primary energy consumption during power generation. 3. It has a wide range of applications and can be widely applied to central heating and cooling in hotels, office buildings, schools, commercial Villas, residential quarters, and other commercial and industrial building air conditioners, it can also be used in swimming pool, dairy processing, beer brewing, cold rolling forging, cold storage, indoor planting, constant temperature breeding and other industries. One machine can be used for cooling, heating and domestic hot water by using one set of equipment. For the air conditioning system, a heat pump provides two kinds of heat sources, which can save one-time investment. Its total investment is only 60% of that of the traditional air conditioning system, and it is easy to install and has less installation workload than other air conditioning systems, the installation period is short and it is easy to change the installation.
