摘要： PROBLEM TO BE SOLVED: To provide refrigeration cycle equipment able to make a secondary refrigerant circuit effectively function when heating operation.SOLUTION: In a primary refrigerant circuit 12, a first expansion valve 23, a third heat exchanger 24 and a second expansion valve 25 are incorporated in this order in a refrigerant pathway 17 between a first heat exchanger 18 and a second heat exchanger 19. A second refrigerant in a secondary refrigerant circuit 13 absorbs heat from a first refrigerant in the third heat exchanger 24 when heating operation. Even if the secondary refrigerant circuit 13 operates in a similar fashion after switching from a refrigerated air conditioning operation to a heating operation as when the refrigerated air conditioning operation is performed, it is prevented that an efficiency of the first heat exchanger deteriorates due to excessive lowering beyond an intended temperature, of an evaporation temperature of the first heat exchanger serving as an evaporator, the excessive lowering may be being caused by action of the third heat exchanger.
