A first blower for forced ventilation, a second blower for forced ventilation of outside air to the second ventilation path, and a control device for controlling the operation of each blower are provided, and this control device is provided for the compressor. When the load is low, the operation of the first and second blowers is stopped or only the second blower is operated, and when the load of the compressor is high, both the first and second blowers are operated. Status Oite is flowed into the compressor from the second condenser as usual outside air by the blower, also air-cooling the compressor by the outside air after cooling the condenser.

上を図ることができるようになるものである。When the load of the compressor becomes high after installation of the refrigerator or after defrosting, the first air blower is also operated to flow the outside air which has not passed through the condenser directly to the compressor, and the outside air having a low temperature strongly increases the temperature. It becomes possible to air-cool the compressor. This makes it possible to quickly eliminate the high load state of the compressor while minimizing the increase in power consumption, thereby improving the operating efficiency and the durability of the compressor.

Stop the operation or only operate the second blower, when it is high, so as to operate both the first and second blowers, quickly determine the state of the load applied to the compressor, The operation can be controlled accurately.
