| 简介 |
PURPOSE : A heat pump type thermo-hygrostat for cold climate area is provided to improve the efficiency of operation in a low temperature environment.CONSTITUTION : A compressor compresses refrigerant to the refrigerant of high pressure and high temperature. An outdoor heat exchanger(200) is located in an outdoor unit(10) and performs heat-exchange with outdoor unit. The expansion valve for cooling decreases the temperature of refrigerant. An air supply part is located on an indoor unit(20) to be supplied to the indoor. An indoor heat exchanger(400) performs heat exchange. A medium pressure generator is connected with a first expansion heating valve and diversifies the refrigerant of medium temperature high-pressure to medium pressure refrigerant. A second expansion heating valve varies the medium refrigerant to the refrigerant of low temperature and pressure. A re-heating device and reheater heat the air supply passing through the indoor heat exchanger. A humidifier performs humidification of the air passing through the re-heating device. A plurality of conduit lines and valve constitutes a cooling cycle or a heating cycle by interlinking elements.COPYRIGHT KIPO 2011 |
