The present invention discloses a system. The system includes a climate condition determination module that is configured to determine a climate condition associated with a vehicle based upon an external air temperature or a dew point temperature. The system also includes a compressor operational state control module that is configured to control a plurality of operational states of a variable displacement compressor of a heating, ventilation and air conditioning system within the vehicle. The compressor operational state control module is configured to cause the variable displacement compressor to selectively transition from a variable displacement operational state to a fixed displacement-like operational state when the climate condition exceeds a climate threshold to cause an evaporatorof the heating, ventilation and air conditioning system to provide evaporator air having an air temperature corresponding to a target evaporator air temperature. 公开了种系统。该系统包括气候条件确定模块，该气候条件确定模块配置为基于外部空气温度或露点温度来确定与车辆相关联的气候条件。该
