Abstract
A refrigeration device (1) has a refrigerant circuit (1E) where a compressor (2), an outdoor heat exchanger (4), an expansion mechanism, an indoor heat exchanger (41) for air conditioning the inside of a room, and cooling heat exchangers (45, 51) for cooling the inside of a chamber are connected. The refrigerant circuit (1E) has a discharge side three-way switchover valve (101) for varying the flow rate of that portion of refrigerant discharged from the compressor (2) which is distributed to both the indoor heat exchanger (41) and the outdoor heat exchanger (4). The refrigeration device (1) has a distribution control section (82) for controlling the discharge side three-way switchover valve (101) to regulate the flow rate of the refrigerant that is distributed to both the indoor heat exchanger (41) and the outdoor heat exchanger (4) in order that the difference between an indoor air temperature and an outdoor air temperature is at a predetermined level in a second heating/refrigerating operation where both the indoor heat exchanger (41) and the outdoor heat exchanger (4) work as condensers.
