Abstract
An oil-lubricated cryocooler compressor that compresses a refrigerant gas of a cryocooler includes a liquid-cooled heat exchanger that cools the refrigerant gas and/or an oil through heat exchange with a coolant and a cooling controller that is configured to acquire a supply temperature of the coolant supplied to the liquid-cooled heat exchanger and to control a flow rate of the coolant of the liquid-cooled heat exchanger and/or an exhaust heat amount of the cryocooler compressor based on the acquired supply temperature of the coolant.
Claims9
An oil-lubricated cryocooler compressor that compresses a refrigerant gas of a cryocooler, the cryocooler compressor comprising:
- a liquid-cooled heat exchanger that cools the refrigerant gas and/or an oil through heat exchange with a coolant;
- and
- a cooling controller that is configured to acquire a supply temperature of the coolant supplied to the liquid-cooled heat exchanger and to control a flow rate of the coolant of the liquid-cooled heat exchanger and/or an exhaust heat amount of the cryocooler compressor based on the acquired supply temperature of the coolant.
An operation method of an oil-lubricated cryocooler compressor that compresses a refrigerant gas of a cryocooler, the cryocooler compressor including a liquid-cooled heat exchanger that cools the refrigerant gas and/or an oil through heat exchange with a coolant, the method comprising:
- acquiring a supply temperature of the coolant supplied to the liquid-cooled heat exchanger;
- and
- controlling a flow rate of the coolant of the liquid-cooled heat exchanger and/or an exhaust heat amount of the cryocooler compressor based on the acquired supply temperature of the coolant.
