ABSTRACT:
A control system for a refrigeration unit incorporating a pressurized liquid gas reservoir is disclosed. The control system is self-contained and suitable for use in the transportation of food in containers. The improvement of the present system is that it avoids overshoot problems in feeding liquid gas coolant to the container. The system includes a gas line from a liquified gas reservoir, a first gas pressure actuated three-way valve, a second gas pressure three-way valve, a first restricting means which provides a time delay for switching the second three-way valve from being connected to the gas line to vent and a second restricting means which provides a second time delay for switching the second three-way valve from vent to the gas line. A temperature sensing control is also incorporated in another embodiment of the invention.
