摘要： An air conditioning system (10) for a passenger compartment of a motor vehicle comprises a first heat exchanger (14) positionable outside the passenger compartment; a second heat exchanger (18) positionable inside the passenger compartment; an expansion device (16) positioned in a first fluid passage (22) between the heat exchangers; an electronically controlled variable stroke compressor (12) for pumping fluid into the second fluid passage and either in a first direction (X) or in a second direction (Y); reverse flow means (32) in the second fluid passage for controlling the direction of the flow of fluid; first sensing means (36) providing a first output signal indicative of the actual temperature of the air leaving the second heat exchanger; second sensing means (40) providing a second output signal indicative of the humidity of the air leaving the second heat exchanger; third sensing means (46) providing a third output signal indicative of the temperature of the air in the passenger compartment; and control means (26,30) electrically connected to the first, second and third sensing means and to the compressor for receiving the first, second, and third output signals, for determining a maximum temperature for the air leaving the second heat exchanger dependent on the second and third output signals, for comparing the determined maximum temperature to the actual temperature, and for controlling the stroke of the compressor to maintain the actual temperature at or below the determined maximum temperature during fluid flow in the second direction. Reduces the risk of unacceptable levels of hot saturated air reaching the passenger compartment.
