Estimating the term…
A cryogenic refrigeration system has a control system that controls the operation of the refrigeration system and provides status information to the operator of the refrigeration system. The cryogenic refrigeration system includes one or more heater and at least one Joule-Thomson valve. The heaters are used to control the recondensing capacity of the refrigeration system and to heat the at least one Joule-Thomson valve and other points to melt away contaminants that may freeze at such points. The control system controls operation of the heaters. The control system also automates an initialization routine that utilizes the heaters to prevent blockage of the valves, and cools the refrigeration system down to a desired temperature. In addition, the control system shuts down the refrigeration system if the status information it monitors exceed a safe range.
A cryogenic refrigeration system, comprising:
In a cryogenic refrigeration system, a method of preventing blockage of a Joule-Thomson valve caused by freezing of contaminants, comprising the steps of:
A control system for controlling the operation of a cryogenic refrigeration system having a Joule-Thomson valve, comprising:
A control system for controlling the operation of a cryogenic refrigeration system comprising
A method of controlling operation of a cryogenic refrigeration system having Joule-Thomson valves and heaters for heating said Joule-Thomson valves, comprising the steps of:
A method of regulating the temperature of a cryogenic refrigeration system having a cryostat and a closed cycle refrigerator within a Joule-Thomson valve liquification system comprising the steps of:
