Abstract: PROBLEM TO BE SOLVED: To solve the problem of delaying in warming-up of an engine by constituting so as to supply cooling water passing through an oil cooler to the engine even at low temperature starting time in a known cooling system for cooling the oil cooler by using a radiator for cooling the engine.
SOLUTION: A refrigerating cycle 11 is operated at low temperature starting time of the engine 1; heat is exchanged by a condenser 5 between a high temperature-high pressure refrigerant forcibly sent from a compressor 12 and the cooling water circularly supplied to the engine 1; and the engine 1 can early be warmed up by effectively using heat conventionally thrown away in the atmosphere from the condenser by quickly raising a temperature of the cooling water supplied to the engine 1. Since the cooling water having a low temperature and having large latent heat and the refrigerant exchange heat in the condenser 5, refrigerant condensing capacity of the condenser 5 is enhanced so that early cooling and early dehumidification can be performed.

Abstract: PROBLEM TO BE SOLVED: To minimize a mounting space in vehicle of a cold storage type air conditioner for a vehicle.
SOLUTION: A liquid refrigerant tank section 10a is integrally formed on the lower portion of a tank member 10. A cold storage heat exchanger 11 is placed in the upper internal portion of the tank member 10. A liquid refrigerant circulating pump 15 is placed underneath the cold storage heat exchanger 11 in the tank member 10. When a compressor is operated, a cold storage material 11a' of the cold storage heat exchanger 11 is cooled down by a low-pressure refrigerant which is depressurized by an expansion valve 7, and the low-pressure refrigerant is flowed into an evaporator through an outlet pipe 14. When the compressor is stopped after a vehicle engine stop, cooling refrigerant of the liquid refrigerant tank section 10a is introduced into the evaporator by the liquid refrigerant circulating pump 15, and is cooled down and condensed by cold/heat storage of the cold storage material 11a' by introducing a gaseous-phase refrigerant which is evaporated by the evaporator into the cold storage heat exchanger 11.

Abstract: PROBLEM TO BE SOLVED: To minimize refrigerant leakage with an inexpensive means.
SOLUTION: Pressure of back pressure chambers 71g and 71h is reduced by suction pressure of a compressor to open the refrigerant inlet side and refrigerant outlet side of an evaporator, and, in stopping the compressor, a first coil spring 76 and a second coil spring 77 mechanically close the refrigerant inlet side and refrigerant outlet side of the evaporator 40. Thus, the refrigerant leakage can be minimized by the inexpensive means. The refrigerant inlet side and refrigerant outlet side of the evaporator are closed during the stopping of the compressor. Therefore, even if refrigerant leakage occurs when an ignition switch is broken over a long time such as in night parking and power is not supplied to a refrigerant leakage sensor and an ECU, a lot of refrigerants can be prevented from filling a room.
