Abstract (en)
[origin: EP3339761A1] The performing of wasteful defrosting, in which a defrosting operation is started when no frost has formed on the outdoor heat exchanger, is prevented. The refrigeration apparatus of the present invention is configured to start a defrosting operation for defrosting an outdoor heat exchanger (13) not only when a first necessary condition is met, which is that a state in which a continuous decrease of an indoor heat exchanger temperature is detected by an indoor heat exchanger temperature sensor (33) continues over a first set time, but also when a second necessary condition is met, which is that a state in which a continuous decrease of an outdoor heat exchanger temperature is detected by an outdoor heat exchanger temperature sensor (23) continues over a second set time.
