Abstract
Disclosed is a low-temperature regenerative type refrigerator installed in a low temperature environment, in which a cooling water flow rate controller for adjusting the flow rate of cooling water automatically in accordance with the temperature of gas fed to an expansion unit from a compressor, is provided in a water cooling type cooler for cooling the compressor, to keep the temperature of the gas discharged from the compressor high to the extent of not deteriorating the function of a seal due to shrinkage or not causing convection or deflecting flow in a regenerator, whereby it is made possible to prevent the deterioration in the cooling efficiency of the regenerator which is caused by a lowering of the ambient temperature in the refrigerator installed place, and hence possible to prevent the deterioration of the refrigerating capacity as the entire refrigerator.
