REFRIGERATING DEVICE

Japanese Patent JP3858918

B2

PROBLEM TO BE SOLVED: To provide a refrigerating device capable of refrigerating inside of the device with only a required cooling heat exchanger and capable of adjusting refrigerating capacity of each cooling heat exchanger respectively, in the refrigerating device provided with a plurality of cooling heat exchangers in a refrigerant circuit serially.
SOLUTION: First and second cooling heat exchangers 131, 141 for respectively cooling inside of the device and first and second expansion mechanisms 132, 142 for respective cooling heat exchangers 131, 141 are provided in the refrigerant circuit 20. In addition, a bypass tube 133 with an end connected to a flow-in end of the first expansion mechanism 132 and the other end connected between the first cooling heat exchanger 131 and the second expansion mechanism 142 is provided in the refrigerant circuit 20. During normal operation, refrigerant is distributed in the first and the second cooling heat exchangers 131, 141 and cooling capacity of the respective cooling heat exchangers 131, 141 is adjusted by the first and the second expansion mechanisms 132, 142. When it is not necessary to cool the first cooling heat exchanger 131, the refrigerant is distributed to the second cooling heat exchanger 141 through the bypass tube 133 and cooling capacity of the second cooling heat exchanger 141 is adjusted by the second expansion mechanism 142.
