FAST COOL DOWN CRYOGENIC REFRIGERATOR

摘要

The present invention is a compressor ; Expanders ; Gas storage tanks; Interconnecting gas line; And a control system comprising a cryogenic refrigeration relates to a system for minimizing the cooling time of the mass body (mass). The output of the compressor is maintained in the vicinity of its maximum volume by maintaining a constant high pressure and low pressure while cooling the vicinity of the gas from the gas storage tank and the injection and discharge to maintain near constant high pressure , the low pressure in order to maintain a near constant speed of the expander is controlled , and characterized in that there is no gas bypass between high and low pressure . ;
