Abstract

A refrigeration device (100) is provided with a refrigerant circuit through which a refrigerant circulates. The refrigerant circuit includes a compressor (1), a heat source-side heat exchanger (2), an auxiliary heat exchanger (3), a first pressure reduction section (4), a utilization-side heat exchanger (5), a second pressure reduction section (6), and a flow passage switching section. The flow passage switching section switches between a first state and a second state. In the first state, the heat source-side heat exchanger (2) and the auxiliary heat exchanger (3) act as a first condenser, the utilization-side heat exchanger (5) acts as a first evaporator, and the refrigerant flows through the compressor (1), the first condenser, the first pressure reduction section (4), and the first evaporator, in that order. In the second state, the utilization-side heat exchanger (5) acts as a second condenser, the auxiliary heat exchanger (3) acts as a second evaporator, and the refrigerant flows through the compressor (1), the second condenser, the second pressure reduction section (6), and the second evaporator, in that order.
