REFRIGERANT FEEDER

Japanese Patent JP2005337510

A

To increase the heating efficiency of a liquid refrigerant by relatively reducing the size of a structure for filling a refrigerant container with a gas refrigerant.

This refrigerant feeder force-feeds the liquid refrigerant in the refrigerant container 1 by a force-feed pump 2 to supply the liquid refrigerant to a product 5 through a supply pipe 3. A return pipe 9 leading to the refrigerant container 1 after branching from the supply pipe 3 is installed on the downstream side of the force-feed pump 2. The liquid refrigerant flowing in the return pipe 9 is heated and evaporated by a heater contained in a refrigerant heating device 10, and the evaporated gas refrigerant is depressed by a pressure reducing valve contained in the device 10. A pressure gauge 11 measuring a refrigerant pressure in a header is installed in the header 8 installed in the supply pipe 3. A temperature sensor 12 detecting the temperature of the refrigerant container 1 is installed in the refrigerant container. A control panel 13 controls the heater 15 based on the detected refrigerant pressure and the temperature of the container.
