US Patent:

6901763, Jun 7, 2005

Filed:

Jun 24, 2003

Appl. No.:

10/602276

Inventors:

Stephen B. Memory - Kenosha WI, US
Jianmin Yin - Kenosha WI, US
Samuel J. Collier - Danville KY, US

Assignee:

Modine Manufacturing Company - Racine WI

International Classification:

F25B041/00

US Classification:

62113, 62503, 62513

Abstract:

The efficiency of refrigeration systems operating on the vapor compression cycle and employing suction line heat exchangers is increased by introducing refrigerant into the lower pressure side of the suction line heat exchanger at a quality less than 1 and introducing refrigerant that has passed through the low pressure side of the suction line heat exchanger into the compressor inlet at a quality that is equal to 1.

International Classification:

B61D 27/00

US Classification:

165 42

Abstract:

The present invention provides a heat exchange system for a vehicle. The heat exchange system can include a first heat exchange circuit supported by the vehicle and fluidly connecting a condenser, a compressor, an evaporator, and an expansion device, a module removably secured to the vehicle, the module housing a pump, and a second heat exchange circuit fluidly connecting a liquid-to-air heat exchanger, the pump, and the evaporator. The first exchange circuit can be operable to condition a first passenger space, and the second heat exchange circuit can be operable to condition a second passenger space spaced apart from the first passenger space.

F25B 7/00
F25B 27/00
F25D 17/00

US Classification:

62115, 62335, 62498, 622387, 62118

Abstract:

The present invention provides a refrigeration system including a first refrigerant circuit including a first heat exchanger for transferring heat from refrigerant, a second refrigerant circuit including a second heat exchanger for transferring heat to refrigerant, and a third refrigerant circuit. The third refrigerant circuit includes a compressor, a condenser connected to the first refrigerant circuit such that heat exchange can occur between the refrigerants of the first and refrigerant circuits, an expansion device, and an evaporator connected to the second refrigerant circuit such that heat exchange can occur between the refrigerant of the second and third refrigerant circuits. The refrigerant can travel along the third refrigerant circuit in a common direction during operation in both heating and cooling modes. Refrigerant can be prevented from moving between first, second, and third refrigerant circuits during operation in heating and cooling modes.
