摘要： Provided is an outdoor unit of a refrigeration apparatus which can suppress a reduction in the total quantity of air passing through the outdoor heat exchanger, which is ensured by a plurality of outdoor fans, when the total blow rate of the fans is lowered. The outdoor unit comprises an outdoor heat exchanger (23), a first outdoor fan (28a) and a second outdoor fan (28b) for generating an air flow passing through the outdoor heat exchanger (23), and a fan controller. The fan controller transitions from a first operating state in which the first outdoor fan (28a) and the second outdoor fan (28b) operate, to a second operating state in which the first outdoor fan (28a) continues to operate and the power supply to the second outdoor fan (28b) is cut off, during low blow rate demand in which a low blow rate is desired. The fan controller, after transitioning to the second operating state, performs fan on/off control for turning the power supply to the first outdoor fan (28a) and the second outdoor fan (28b) on and off on the basis of a timer, observation of an electric current value relating to fan motors, or observation of the fan rotational speeds.

摘要： To provide, at a low cost, a refrigeration device in which an appropriate oil concentration or oil viscosity can be readily maintained with regards to lubricating oil in a compressor and in which a cut in standby power can be achieved. The compressor (40) compresses a refrigerant circulating between an indoor heat exchanger (21) and an outdoor heat exchanger (31). A crank case heater (46) heats the lubricating oil in the compressor (40). A control device (50) controls the crank case heater (46). The control device (50) controls the crank case heater (46) so that the oil temperature of the lubricating oil in the compressor (40) reaches an oil temperature target value obtained by adding an oil temperature offset value to the saturation temperature of the refrigerant in the compressor (40).
