Abstract
An air conditioner for a vehicle comprises a refrigerating cycle including a compressor, a condenser, an undercooling heat exchanger, an expansion valve, an evaporator disposed in an air duct. The air conditioner further comprises a heater core arranged at a downstream of the evaporator to pass the conditioned air therethrough, and an air-mix door for use in adjusting air flow to be passed through the heater core. The undercooling heat exchanger is disposed at the downstream of the evaporator within the air duct, and is supplied with the conditioned air when the conditioned air is sent to the heater core when the air-mix door is opened.
Claims5
An air conditioner for a vehicle comprising:
- a refrigerating cycle including a compressor compressing a gasified refrigerant into a compressed refrigerant, a condenser condensing said compressed refrigerant into a liquid refrigerant, an undercooling heat exchanger undercooling said liquid refrigerant into a cold liquid refrigerant, an expansion means for expanding said cold liquid refrigerant into an expanded refrigerant, an evaporator evaporating said expanded refrigerant, said evaporator being disposed in an air duct, said undercooling heat exchanger being disposed at the downstream of said evaporator within said air duct;
- and
- a control means for controlling said refrigerating cycle so as to supply to said undercooling heat exchanger with said conditioned air.
