車両用ヒートポンプ装置
Document Type and Number:
Japanese Patent JP4211186
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To favorably perform defrosting for an exterior heat exchanger by effectively restraining heat radiation to running wind even during running of a vehicle in defrosting the exterior heat exchanger. SOLUTION: In a heating mode in which the exterior heat exchanger 9 serves as an evaporator, the refrigerant evaporating pressure is lowered on the refrigerant outlet side of the exterior heat exchanger 9, so that the refrigerant evaporating temperature drops. Therefore, frosting is caused on the refrigerant outlet side of the exterior heat exchanger 9. At the rise of the heating mode, the refrigerant is let flow from the leeward heat exchanging part 92 of the exterior heat exchanger 9 to the windward heat exchanging part 91, and in defrosting during running, a high pressure side refrigerant is let flow into the leeward heat exchanging part 92 only. Thus, the windward heat exchanging part 91 fulfils the action of intercepting running wind, thereby favorably defrosting the leeward heat exchanging part 92.
