ABSTRACT:
A thermoelectric refrigerant handling system that includes a chamber having an inlet path for receiving refrigerant from a source thereof and an outlet for delivering refrigerant in vapor phase. A thermoelectric element is operatively disposed between the chamber and the refrigerant inlet path, and is responsive to application of electrical energy for transferring heat from the inlet path to the chamber. In this way, heat is withdrawn from refrigerant at the inlet path and refrigerant is drawn into the inlet from the source, while heat is added to refrigerant in the chamber until the refrigerant is vaporized and driven by vapor pressure through the chamber outlet. A controller applies electrical energy to the thermoelectric element for transferring heat into the chamber to vaporize the refrigerant contained therein until the chamber is substantially empty of refrigerant, and then opens a valve to feed refrigerant from the inlet path to the chamber. In this way, refrigerant is drawn from the source through the inlet, and effectively pumped in vapor phase through the outlet of the chamber.
