である。According to the present invention, compared to the gas pressure in the refrigerant gas return pipe that is sucked into the compressor via the evaporator,
This method takes advantage of the fact that the gas pressure in the pipes of the refrigerant gas injection circuit is always high, and the high proportion is roughly proportional to the size of the load on the refrigeration equipment.The motor placed in the refrigerant gas injection circuit The refrigerant gas injection circuit is driven by the gas pressure flowing toward the compressor, so there is no need for any electric power to drive the motor, and the motor rotation speed, that is, the fan rotation speed, is controlled by the refrigerant gas injection circuit according to the load of the refrigeration equipment. Since this corresponds to the difference between the gas pressure inside the refrigerant gas return pipe and the gas pressure inside the refrigerant gas return pipe, it is possible to prevent the generation of noise caused by unnecessarily high speed rotation.

A refrigeration circuit 5 in which the refrigerant flows from the air to the condenser 2, from the gas-liquid separator 3 to the evaporator 4 and to the compressor 1.
, the refrigerant gas enters the refrigerant gas return vibrator from the evaporator 4 and is sucked into the compressor 1 via the compressor vibrator 7.

る。C. A motor 11 is disposed in the refrigerant gas injection circuit 8 described above and is driven to rotate by the refrigerant gas flowing in the circuit 8 toward the compressor 1.
is used as a driving source for the cooling fan 12 of the condenser 2.

＜、シかもその高圧の割合は冷凍装置の負荷の大きさに
概ね比例するので。In general, the refrigerant gas pressure in the refrigerant gas injection circuit 8 is higher than the refrigerant gas pressure in the refrigerant gas return valve 6, but the proportion of the high pressure is roughly proportional to the size of the load on the refrigeration system. Because I do.

１２も低速回転となるものである。When the load on the refrigeration system is large and the cooling capacity of the condenser 2 is also required to be large, the refrigerant gas pressure in the refrigerant gas injection circuit 8 becomes significantly higher than the refrigerant gas pressure in the refrigerant gas return vibro.
The cooling fan 12 is rotated at high speed, and when the load on the refrigeration system is small, the refrigerant gas pressure in the refrigerant gas injection circuit 8 is low, and the difference between the refrigerant gas pressure and the refrigerant gas pressure in the refrigerant gas return vibro is small. Therefore, the motor 11 and cooling fan 12 also rotate at low speed.
