PROBLEM TO BE SOLVED: To provide an air conditioner capable of preventing freezing an outdoor side heat exchanger during heating operation. SOLUTION: A refrigerating cycle is provided, comprised by sequentially connecting a compressor 1, a four-way valve 2, an indoor side heat exchanger 3, a pressure reducer 4, and the outdoor side heat exchanger 5. A receiver tank 6 is provided for passing a coolant in a high temperature high pressure state before being compressed by the compressor 1 and supplied to indoor heating. The receiver tank 6 is arranged on the outdoor side heat exchanger 5, heat of the receiver tank 6 passing the coolant in the high temperature high pressure state is used to prevent freezing of fins and tubes of the outdoor side heat exchanger 5, and heating performance can be secured.
