Abstract
An air conditioning system, a vehicle and a method of controlling the vehicle with a vehicle air conditioning system are provided. The vehicle air conditioning system has a refrigeration circuit having a compressor, a condenser, and an evaporator in sequential fluid communication, with a valve assembly and a battery chiller positioned for parallel flow with the evaporator. A cooling circuit in the vehicle has a chiller. A controller is configured to, in response to a temperature of the evaporator being less than a first predetermined value and the compressor operating at a predetermined speed, open the valve assembly to divert a portion of refrigerant through the chiller and away from the evaporator. The refrigerant may be diverted, for example, to raise the temperature of the evaporator and/or prevent cycling of the compressor.
