Abstract
When the air blowing amount of a bloweris large, a high pressure is controlled so as to be increased higher than when the air blowing amount by the bloweris small. By this construction, refrigerant noise is drowned out by air noise and is made difficult to hear. In addition, in general, as a high heating capability is required when the air blowing amount is large and, on the contrary, a high heating capability is not required when the air blowing amount is small, in the event that the high pressure is controlled based on the air blowing amount, the noise attributed to the refrigerant noise, that is felt by the occupants when heating is performed using the hot gas, can be reduced without damaging the sense of being heated.
