Abstract
Uncomfortable air temperatures in an air conditioned vehicle immediately following start up of the air conditioning system or when the air conditioning system compressor is being driven at low speeds are avoided in a cooling system including a blower (22) for blowing air into a compartment (10). An air/liquid heat exchanger (30) is located at the outlet (34) of the blower (22) for cooling air received from the blower (22). The system includes a compressor (50), an expansion device (58), a condenser (54) and a liquid/refrigerant evaporator (64) for expanding refrigerant and cooling a liquid coolant which is circulated through a thermal storage device (92) and the heat exchanger (30) by a pump (86). Upon system start up, or when the compressor (50) is being driven at low speed, the coolant is cooled by the thermal storage device (92) to provide a means of cooling air from the blower (22). At all other times, the coolant is cooled by expansion of refrigerant within the evaporator (64) to not only provide a coolant for use in the heat exchanger (30), but a coolant for recharging the thermal storage device (92) as well.
