Embodiment Construction

[0017] see now figure 1 , which depicts an exemplary embodiment of a refrigerant vapor compression system 10 suitable for use in a transport refrigeration system to refrigerate trucks, trailers, containers, or the like for transporting perishable / frozen goods Temperature controls the air or other gaseous atmosphere within the cargo space. The refrigerant vapor compression system 10 is also suitable for conditioning air supplied to a climate-controlled comfort zone within a residence, office building, hospital, school, restaurant, or other facility. Refrigerant vapor compression systems may also be used to refrigerate the air supplied to display cases, showcases, freezers, cold rooms, or other perishable / frozen product storage areas in commercial establishments.

[0018] The refrigerant vapor compression system 10 is particularly suited to operate in a transcritical cycle utilizing a low critical temperature refrigerant such as, but not limited to, carbon dioxide. It should b...

Abstract

A refrigerant vapor compression system includes a hot gas bypass line establishing refrigerant vapor flow communication between the compression device and the refrigerant heat absorption heat exchanger, and bypassing the refrigerant heat rejection heat exchanger and the primary expansion device. A refrigerant vapor flow control device is interdisposed in the hot gas bypass line. The flow control device has at least a first open position in which refrigerant vapor flow may pass through the hot gas bypass line and a closed position in which refrigerant vapor flow may not pass through the hot gas bypass line.
