Abstract
With the intention of reducing power consumption and noise, there is provided a binary refrigeration unit which can be started even by a compressor equipped with a small-torque and compact motor. The binary refrigeration unit is constructed in such a manner that an evaporatorof a high-temperature side refrigerant circuit H and a condenserof a low-temperature side refrigerant circuit L are disposed side by side, a refrigerant of the low-temperature side refrigerant circuit L is cooled to be condensed at the condenserby vaporization heat of a refrigerant of the high-temperature side refrigerant circuit H evaporated by the evaporator, the condensed refrigerant of the low-temperature side refrigerant circuit L is evaporated at an evaporator, and accordingly a low temperature much lower than a low temperature obtained by the evaporatoris obtained by the evaporator. A refrigerant tankis connected to a low-pressure side which is a suction side of a compressorof the high-temperature side refrigerant circuit H through a connecting pipeby interposing a capillary tube
