Advantages of water source heat pump
The groundwater type water source heat pump unit takes the groundwater, collects the low-grade heat energy in the groundwater in winter, USES the heat pump system, consumes part of the electric energy, supplies the energy to the indoor heating; Take out indoor heat in summer, release to water, in order to achieve the purpose of summer air conditioning. The unit has the advantages of design standard, excellent selection, simple operation, safety and reliability. As water source heat pump technology USES shallow groundwater as the source of refrigeration and heating of air conditioning units, it has the following advantages:
(1) Water source heat pump (WSHP) is a heating and air conditioning system that USES groundwater as a heat and cold source for energy conversion. The boiler room system, such as coal burning, gas and natural oil, is saved during heating. There is no burning process, which avoids smoke emission pollution. The cooling water tower is eliminated during cooling, and the noise and mold pollution of the cooling tower are avoided. Do not produce any waste residue, waste water, waste gas and smoke, make the environment more beautiful. Solved the boiler dirty mess and waste discharge problem. At the same time, to solve the government restrictions on the use of small boilers.
(2) The water temperature available for the high-efficiency energy-saving water source heat pump unit is 8 ~ 30℃ in winter, and the water temperature is higher than the ambient air temperature, so the evaporation temperature of the heat pump cycle is increased, and the energy efficiency ratio is also improved. In summer, the water body is 10-35℃, and the water body temperature is lower than the ambient air temperature, so the cooling condensation temperature is reduced, which makes the cooling effect better than the cooling tower, and the unit efficiency is improved. The EPA estimates that well-designed water source heat pumps can save users, on average, 30 to 50 percent of their heating, cooling and air conditioning operating costs.
(3) The temperature of water body with stable and reliable operation 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. There are no difficult problems such as winter defrosting of air source heat pump. (4) One multi-purpose machine, wide application range of water source heat pump system can provide heating, air conditioning, sanitary hot water and other functions, one multi-purpose machine, one set of system can replace the original boiler and air conditioning two sets of devices or systems.
(5) Due to stable operating conditions, a simple system can be designed with fewer components, simple and reliable operation of the unit and low maintenance cost; High degree of automatic control, long service life can reach more than 20 years.
Water source heat pump system is a reliable, economical and energy - saving way of air conditioning. Moreover, the cost and machine room area of the air conditioning system are reduced because the water source heat pump replaces the water-cooled screw and the boiler (solving the problem of floating water in the cooling tower and serious pollution of the gas boiler). In addition, since the water source heat pump USES clean energy, the COP of the system is much higher than that of the water-cooled screw and boiler system, with obvious energy saving effect and operating cost much lower than that of the water-cooled screw and boiler system. Energy saving is environmental protection, in the electricity has entered the buyer's market, in the condition of rapid improvement in people's living conditions, water source heat pump will undoubtedly be a popular way of air conditioning.
