摘要： Provided is an air conditioner for a vehicle which can prevent the controls over cooling cycle and heating cycle from interfering with each other and thereby prevent hunting between the cooling and heating cycles even when a compressor is operated to perform the heating cycle in an overlapping temperature range where air cooling and air heating are both required. An air conditioner (4) for a vehicle includes a refrigerant circulation circuit (9b) for air heating to circulate a refrigerant, and a control unit (29) to selectively perform a normal air conditioning mode in which a normal cooling operation is feasible by circulating the refrigerant through a refrigerant circulation circuit (9a) for air cooling and an auxiliary heating mode in which an auxiliary heating operation is performed by circulating the refrigerant through the refrigerant circulating circuit (9b) for air heating.

摘要： Provided is a vehicle air conditioning device with a simple structure which can quickly raise the temperature of engine cooling water used for heating the air in a vehicle cabin in an engine start period in a low ambient temperature. The vehicle air conditioning device comprises the following elements integrally connected with each other: a first water heat exchanger (26) provided in the middle of a passage through which an engine cooling water flows from the water jacket of an engine (3) to a heater core (8a), a second water heat exchanger (27) provided in the middle of a passage through which the engine cooling water flows from the heater core (8a) to the water jacket of the engine (3), and a first external heat exchanger (18) for refrigerant condensation provided between the first and second water heat exchangers (26, 27). In the engine start period in a low ambient temperature, the engine cooling water flowing from the water jacket to the heater core (8a) is heated by heat released from the first external heat exchanger (18) to rise in temperature.

摘要： A ventilation load-reducing apparatus, which has a simple structure and is capable of further improving the efficiency of the heat recovery, and a vehicle air conditioner using the same are proposed. The ventilation load-reducing apparatus includes an inside air lead-out path 4 for ventilation which leads air of a vehicle-interior out of a vehicle from a rear side of the vehicle-interior, an outside air lead-in path 5 which leads outside air into a front side of the vehicle-interior, a ventilation heat recovery device 6 which recovers heat from the air led out through the inside air lead-out path 4, a recovered heat radiator 7 which releases the heat on the air led in through the outside air lead-in path 5, and a heat transmitter 8 which transmits the heat between the ventilation heat recovery device 6 and the recovered heat radiator 7. The ventilation load-reducing apparatus is independent of a refrigerant circulating system 9 of a vehicle air conditioner 2.
