Abstract: A system and method includes a thermoelectric device in heat-transfer relation with a working fluid flowing through a vapor compression circuit. Heat is transferred from the working fluid to a first fluid medium and then from the first fluid medium to a second fluid medium.

Abstract: A scroll compressor an orbiting scroll member including a second end plate, a second wrap extending from the second end plate and meshingly engaged with the first wrap to form a suction pocket in fluid communication with a suction pressure region of the compressor, intermediate compression pockets, and a discharge pocket in fluid communication with the discharge passage. An auxiliary passage is in fluid communication with one of the intermediate compression pockets to provide pressurized fluid to the chamber to deflect the first end plate and the first wrap axially toward the orbiting scroll member.

Abstract: Scrolls made from injection molding processes are disclosed. The scroll components have a tip seal groove defined within an involute portion of the scroll. Bearing and tip seal engaging plates are integrally molded within base members of the scroll.

Abstract: A system and method includes a vapor compression circuit having a source of waste heat. A thermoelectric device is positioned in heat-transfer relation to the source of waste heat and generates an electric current that powers a load.

Abstract: A system and method includes a vapor-compression circuit having a working fluid flowing therethrough, a thermoelectric device positioned in a heat-transfer relation with the working fluid, and a power supply providing current to the thermoelectric device to generate a heat flow through the thermoelectric device.

Abstract: A scroll type compressor has both a high pressure lubricant sump and a low pressure lubricant sump. Lubricant from the low pressure lubricant sump is supplied to the various bearings, thrust surfaces and other moving components of the compressor. It is then rested in such a way that it can absorb heat from the motor windings thus maintaining the operating temperature of the motor. Lubricant from the high pressure sump is supplied to the moving compression chambers defined by the scrolls at a point intermediate suction and discharge. The lubricant supplied from the high pressure sump is first cooled and then used to cool the low pressure sump prior to being supplied to the moving compression chambers. The compressed gas is routed through two lubricant separators and a gas cooler prior to being supplied for its intended use.
