AIR CONDITIONING SYSTEM FOR VEHICLE

摘要

Provided are a heat-pump cooler (A) having a first circulation channel (1) and a heater circulator (B) having a second circulation channel (8). A water-cooling condenser (3) in the first circulation channel (1) is placed in the second circulation channel (8), and causes the first coolant to release its heat to the second coolant. The second circulation channel (8) includes a passage switching valve (14) for switching the passage between a passage passing a radiator (10) and a radiator bypass passage (13). During a heating operation, the passage switching valve (14) causes the second coolant to flow into the radiator bypass passage (13), and the air heated by a heater core (12) is introduced as air-conditioned air into the vehicle cabin. During a cooling operation, the passage switching valve (14) causes the second coolant to flow into the radiator (10), and the air cooled by an evaporator (6) is introduced as air-conditioned air into the vehicle cabin.
