Heat transfer process in the central air conditioning system?
The central air conditioning mainly by air conditioning compressor suction cold coal gas from the evaporator in the normal temperature and low pressure compressed into cold coal gas of high temperature and high pressure, sufficient heat exchange with cooling water in the condenser, cooling water absorbs heat, cold coal by using tower fan cooling pump to the cooling tower with the spray cooling water to heat exchange, Lin will heat released into the atmosphere; Then after cooling into cold coal low temperature and low pressure liquid, the regulator in the evaporator heat absorption of frozen water, into the normal temperature, low pressure cold coal gas to air conditioning compressor, single cycle finished cold coal; Cold and chilled water for coal in the process of evaporation heat is absorbed, becomes lower temperature of cold water, through the frozen pump to the end of the air conditioning equipment (fan coil) with indoor air heat exchange, aim to reduce indoor air temperature
Heat energy into evaporator heat transfer to the refrigerant, refrigerant sent refrigerant compressor after gasification pressure again after ascending temperature, refrigerant entering the condenser, the heat transfer in the condenser to the indoor heat carrier of water, water is heated by the water pump into the room after using, enhance room temperature or bathing, refrigerant and cooling liquid, then through expansion valve step-down cool to go back to the evaporator absorbs heat from the heat source to send.
