<p><P>PROBLEM TO BE SOLVED: To provide a vehicle air conditioner that properly adjusts the amount of absorbed heat in an outdoor heat exchanger to obtain proper amount of heat dissipation in a heat radiator in heating mode and dehumidification/heating mode, and proper amount of heat absorption in a heat absorbing unit. <P>SOLUTION: During the heating mode, a predetermined value A is set as a target super heat SHt. During the dehumidification mode, a value calculated on the basis of the outdoor temperature Tam and a target temperature Tet of a heat absorbing unit 14 is set as the target super heat SHt. The opening degree of a first expansion valve 27a is controlled on the basis of the above target super heat SHt and a super heat SH of refrigerant calculated on the basis of a pressure P of the refrigerant in the outdoor heat exchanger 22 and the temperature Thex of the refrigerant flowing out of the outdoor heat exchanger 22. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
