Abstract
A refrigeration apparatus () is provided with a refrigerant circuit (E) along which are connected a compressor (), an outdoor heat exchanger (), an expansion mechanism, an indoor heat exchanger () for providing room air conditioning, and a cooling heat exchanger () for providing storage compartment cooling. The refrigerant circuit (E) includes a discharge side three way switch valve () for varying the flow rate of a portion of the refrigerant which is discharged out of the compressor () and then distributed to the indoor heat exchanger () and the outdoor heat exchanger () during a heat recovery operation mode in which the indoor heat exchanger () and the outdoor heat exchanger () operate as condensers. As a result of such arrangement, even when the amount of heat obtained in the cooling heat exchanger () exceeds the amount of heat required in the indoor heat exchanger (), surplus heat is discharged without excessive decrease in the discharge pressure of the compressor ().
