摘要
空气源CO2热泵在冬季运行时,由于外部环境温度低、空气湿度大等原因,往往会在蒸发器表面形成霜层,从而降低热泵运行效率,甚至影响热泵机组的正常运行,根据CO2热泵的实际应用,设计一种CO2热泵智能除霜方法,用于解决空气源CO2热泵低温、高湿环境下的除霜问题。
Air source CO2 heat pump running in winter, due to the external environment of low temperature, high air humidity and so on, often formation frost layer in the evaporator surface, thereby reducing the efficiency of the heat pump, and even affect the normal operation of the heat pump units, this paper will according to the practical application of the CO2 heat pump, design a CO2 heat pump intelligent defrosting method, is used to solve the CO2 air source heat pump defrost problem under the low temperature, high humidity environment.
