The advantages of water source heat pump units
(1) It belongs to renewable energy utilization technology. Water source heat pump (WSHP) is a heating and air-conditioning system which USES the solar energy stored in the earth water body as the heat and cold source for energy conversion. The available water bodies include groundwater or rivers, soil, surface rivers and lakes, and oceans. The surface soil and water is a huge solar collector, collected 47% of the solar radiation energy, 500 times more each year than humans use energy (underground water through the soil indirectly accept solar radiation energy), and it is a huge dynamic energy balance system, soil and water on the surface of the earth naturally to maintain the relative balance of the energy acceptance and divergence, which makes the use of stored in the almost limitless solar or can become possible. Therefore, the water source heat pump USES a clean renewable energy technology.
(2) High efficiency and energy saving. The water temperature available for the water source heat pump unit is 12-22℃ in winter, and the water temperature is higher than the ambient air temperature, so the evaporation temperature of the heat pump cycle is improved, and the energy efficiency ratio is also improved. In summer, the water body is 18-35℃, and the water body temperature is lower than the ambient air temperature, so the condensation temperature of refrigeration is reduced, which makes the cooling effect better than the air-cooled type and cooling tower type, and the unit efficiency is improved. The EPA estimates that well-designed water source heat pumps can save, on average, 30 to 40 percent of heating, cooling and air conditioning costs. (3) Stable and reliable operation. The temperature of water is relatively stable throughout the year, and its fluctuation range is far less than that of air. It is a good heat pump heat source and air conditioning cold source. The constant water temperature makes the operation of the heat pump unit more reliable and stable, and also ensures the high efficiency and economy of the system.
(4) Significant environmental benefits. The water source heat pump USES electricity, which is itself a clean energy source that emits no carbon dioxide and does not require a coal yard. The power consumption of the water source heat pump unit can be reduced by more than 30% compared with the air source heat pump and more than 70% compared with the electric heating. The refrigerant used in water source heat pump can be R22 or R134A, R407C, R410A and other alternative working medium. The operation of the water source heat pump unit is free from any pollution and can be built in the residential area. There is no burning, no smoke exhaust and no waste. There is no need to pile up the fuel waste site and no long-distance heat transfer.
(5) A multi-purpose machine. Water source heat pump system can provide heating, air conditioning and domestic hot water. One machine is multi-purpose. One set of system can replace the original two sets of boiler and air conditioning units or systems. Especially for buildings with heating and cooling requirements, water source heat pump has obvious advantages. It not only saves a lot of energy, but also can meet the requirements of heating and cooling with one set of equipment, reducing the initial investment of equipment. Water source heat pump can be used in hotels, shopping malls, office buildings, schools and other buildings.
(6) High degree of automation. Due to stable operating conditions, the water source heat pump unit can be designed with a simple system with fewer components, simple and reliable operation, and low maintenance cost. High degree of automatic control, long service life can reach more than 15 years, the machine room can realize unattended.
