An air conditioning apparatus (301) includes a flow path switching valve (202). An outdoor heat exchanger (40) is divided into a first heat exchanger (40A) and a second heat exchanger (40B). During heating operation, a refrigerant supplied from an expansion valve (30) is diverted and supplied to the first heat exchanger (40A) and the second heat exchanger (40B). During the heating operation, the flow path switching valve (202) combines the flows of the refrigerants discharged from the first heat exchanger (40A) and the second heat exchanger (40B), and returns the resultant refrigerant to a refrigerant inlet of a compressor (10). A valve body (203) of the flow path switching valve (202) is configured such that three ports (B1, B2 and C) are internally communicated with one another while being isolated from an other single port (A) during the heating operation. The valve body (203) is configured such that two ports (A and B 1 or A and B2) are internally communicated with each other and other two ports (B2 and C or B 1 and C) are internally communicated with each other during defrosting operation of the first heat exchanger (40A) or the second heat exchanger (40B).
