Abstract
An air conditioning apparatus includes a flow path switching valve. An outdoor heat exchanger is divided into a first heat exchanger and a second heat exchanger. During heating operation, a refrigerant is diverted and supplied to the first heat exchanger and the second heat exchanger. During the heating operation, the flow path switching valve combines the flows of the refrigerants discharged from the first heat exchanger and the second heat exchanger, and returns the resultant refrigerant to a refrigerant inlet of a compressor. Three ports of the flow path switching valve are internally communicated with one another while being isolated from an other single port during the heating operation. Two ports of the flow path switching valve are internally communicated with each other and other two ports are internally communicated with each other during defrosting operation of the first heat exchanger or the second heat exchanger.
