Abstract:
A refrigeration apparatus is configured to start a defrosting operation for defrosting an outdoor heat exchanger 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 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 continues over a second set time. The performing of wasteful defrosting, in which a defrosting operation is started when no frost has formed on the outdoor heat exchanger, is prevented.

Claim (Index 1):
A refrigeration apparatus comprising:\n a refrigeration circuit capable of repeating a vapor-compression refrigeration cycle by channeling refrigerant sequentially through a compressor, an indoor heat exchanger, an expansion mechanism, and an outdoor heat exchanger; a first sensor capable of detecting an indoor heat exchanger temperature of the indoor heat exchanger; and a second sensor capable of detecting an outdoor heat exchanger temperature of the outdoor heat exchanger, wherein the refrigeration apparatus is configured to start a defrosting operation for defrosting the outdoor heat exchanger when a first necessary condition and a second necessary condition are met, the first necessary condition being that a state in which a continuous decrease of the indoor heat exchanger temperature is detected by the first sensor continues over a first set time, the second necessary condition being that a state in which a continuous decrease of the outdoor heat exchanger temperature is detected by the second sensor continues over a second set time, and the second necessary condition is determined to have been met when average values of sampling values of the outdoor heat exchanger temperature within respective predetermined sampling times, detected by the second sensor, continue to not increase for at least a predetermined number of times.
