Warmer weather in South China, only in summer cooling, the other most of all for the summer and cold winter, so take summer cooling and winter Heating . As the northern winter, cooled Heat Pump Can only be used for the transition season Heating And Boiler The use by the capacity constraints in urban areas, LiBr direct burning of fuel prices as oil prices rise, more fuel used in the past the use of lithium bromide units higher cost. Therefore, in recent years, able to use the rivers, lakes, sea, and urban native Sewage Areas, sewage Water Source Heat Pump Technology is increasingly popular.
In Beijing, the Northeast, Shanxi, Shandong and other places, there are many Project Using water source heat pump technology. Current owner and design unit to promote using this water source heat pump technology is the main driving force: 1, City Environmental protection Requirements do not allow to set the boiler room and chimney, no Environment Pollution; 2, can work simultaneously to solve the cold air conditioning, heat problems; 3, initial investment costs and operating expenses province; 4, winter heating efficiency of above 3.2. The driving force of the water source heat pump technology rapidly into the actual project, no doubt play an important role in promoting, to break the air conditioning and air-conditioning system in China too monotonous situation, play a better role in promoting.
Water source heat pump works As a phenomenon of nature, heat always flow from high temperature low temperature zone. As to who is promoted to higher from the lower, like the use of pumps, water source heat pump technology can be used to transfer heat from low temperature to high temperature. The principle of heat pump and refrigeration equipment and systems is the same as the composition and function of compression heat pump heat pump (cooling) system consists of the compressor, evaporator, condenser and the throttling device component. Compression and transmission compressor plays a low temperature low pressure refrigerant from office to office the role of high temperature and pressure, is the heat pump (cooling) system of the heart; evaporator is the cooling capacity output of the device, which allows the cooling liquid through the throttle into the evaporator, to absorb the heat by cooling medium to achieve the purpose of refrigeration; condenser is the heat output of the device, absorbing heat from the evaporator with the compressor power consumption of heat by the conversion of North cooling medium in the condenser removed, to heating of the purpose; throttling device throttling of refrigerant to play the role blood pressure, and adjust the refrigerant into the evaporator flow rate.
According to the second law of thermodynamics, water source heat pump compressor power consumption (energy) play a role not long, is constantly refrigerant absorbs heat from the low-temperature environment, and to high environmental heat, Week to loop back and forth to.
