PROBLEM TO BE SOLVED: To provide an air conditioning equipment for a vehicle wherein a refrigerant recovering operation is completed fast even when refrigerant piping of a refrigerating cycle is long, as is the case of a bus or the like, and heating is not interrupted either during the refrigerant recovering operation. SOLUTION: In the case when a refrigerant is recovered in a heating operation, a control circuit puts a cooling-heating selector valve 23 in a state of opening and a cooling-heating selector valve 24 in a state of closure, and puts a recovery selector valve 27 in the state of closure and an opening-closing solenoid valve 26 in the state of opening. The refrigerant stagnating in the refrigerating cycle is taken in an accumulator 20 through bypass piping 25 for recovering the refrigerant, so as to be recovered.
