is located.

The operation of the refrigeration system 1 configured as described above will be described below.

The above-mentioned refrigeration device 1 constitutes a refrigeration system in combination with another cooling device (not shown). When the high-temperature, high-pressure refrigerant gas compressed by the compressor 7 passes through the heat exchanger 4, it is cooled by the airflow generated by the 77 fan 6, which rotates by the drive of the blower 6, and becomes a room-temperature and high-pressure refrigerant liquid, which is then sent to the refrigeration system. Exit from 1 and head to the cooling device. In the cooling device, the refrigerant liquid is depressurized and evaporated to become a low-pressure refrigerant gas. At this time, the cooling device exerts its cooling effect by absorbing heat from the surrounding air. The low-pressure refrigerant gas discharged from the cooling device is returned to the refrigeration device 1 and compressed by the compressor 7, and the above cycle is repeated to form a refrigeration sile.

Problems that the invention aims to solve However, in the above configuration, the heat exchanger.

The blower and compressor each occupy space (capacity), and the problem is that the space occupied by the blower in particular has a large dead space, which has become an obstacle to saving space through miniaturization as required by industry.
