Title:
AIR CONDITIONER FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2011/070779
Kind Code:
A1
Abstract:
Provided is an air conditioner for vehicles, wherein it is possible to reduce the number of parts and assembly steps and to occupy less space by integrally configuring the plurality of parts used to configure a refrigerant circuit. A refrigerant circuit (1) is provided with a cold storage internal heat exchanger (10) having: a high-pressure refrigerant storage unit (11) through which the high-pressure refrigerant on the downstream side of a condenser (3) flows; a low-pressure refrigerant storage unit (12) through which the low-pressure refrigerant on the downstream side of an evaporator (5) flows; and a heat storage material housing unit (13) which houses a heat storage material therein. The cold storage internal heat exchanger (10): exchanges the heat between the high-pressure refrigerant in the high-pressure refrigerant storage unit (11) and the low-pressure refrigerant in the low-pressure refrigerant storage unit (12); cools the cold storage material stored in the cold storage material housing unit (13) by means of the low-pressure refrigerant in the low-pressure refrigerant storage unit (12) when a compressor (2) is activated; cools, by means of the cold storage material housed in the cold storage material housing unit (13), the high-pressure refrigerant in the high-pressure refrigerant storage unit (11) after the heat of the high-pressure refrigerant was exchanged with the low-pressure refrigerant in the low-pressure refrigerant storage unit (12); and cools the low-pressure refrigerant in the low-pressure refrigerant storage unit (12) by means of the cold storage material housed in the cold storage material housing unit (13) when the compressor (2) is stopped.
