High temperature heat pump hot water unit in the main components are compressors, evaporators, condensers, expansion valves, etc., and filled with environmentally friendly refrigeration.
High temperature heat pump unit output hot water temperature than ordinary heat pump production of hot water temperature, with the ordinary heat pump working principle is the same, but the production of hot water is more powerful.
At work, through a small amount of high electrical energy input, the vaporization of the refrigerant is compressed, so that its temperature and pressure rise, high-temperature high-pressure refrigerant flow human condenser, heat transfer to the water around the condenser, the cooling refrigerant condensed into a high-pressure liquid left condenser, through the expansion valve rapid pressure relief. Some liquid refrigerants become gases, causing the remaining refrigerant to quickly become cold, forming a mixture of cryogenic liquids and gases leaving the expansion valve; After entering the evaporator, this cryogenic mixture absorbs heat from the environment in the evaporator, evaporates the liquid part of the refrigerant and moves backwards to the low pressure end of the compressor. In this way, the continuous circulation of a large number of low-temperature low-grade thermal energy in the environment, to achieve low-temperature thermal energy to high thermal energy, so that in the hot water storage box to obtain 50 ℃ 80 ℃ of domestic hot water, for life and production use.
