<p><P>PROBLEM TO BE SOLVED: To provide a vehicular air conditioner and a control method of the vehicular air conditioner for preventing reduction in heating efficiency even in heating operation when an outside air temperature is low. <P>SOLUTION: A heat pump type vehicular air conditioner 10A is characterized in that a refrigerant circuit has a compressor 11 for compressing a gas refrigerant, vehicle-inside heat exchangers 12 and 13 for exchanging heat between outside air or indoor air and the refrigerant, an orifice mechanism 15 for decompressing the refrigerant, a vehicle-outside heat exchanger 14 for exchanging heat between the outside air and the refrigerant and refrigerant flowing direction switching means 16A and 16B for selectively switching the refrigerant flowing direction, and the vehicle-outside heat exchanger 14 has an outside air introducing part 35 for introducing the outside air to the vehicle-outside heat exchanger and a flow rate limiting means 36 for limiting an inflow moisture quantity from the vehicle-outside, and the flow rate limiting means 36 limits an inflow moisture quantity from the vehicle-outside in a heating operation mode. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
