Title:
Transcritical steamy compression system
Document Type and Number:
Japanese Patent JP6082059
Kind Code:
B2
Abstract:
To accommodate a transcritical vapor compression system with an operating envelope which covers a large range of heat source temperatures, a high side pressure is maintained at a level determined not only by operating conditions at the condenser but also at the evaporator. A control is provided to vary the expansion device in response to various combinations of refrigerant conditions sensed at both the condenser and the evaporator in order to maintain a desired high side pressure.
