Embodiment Construction

[0011]FIG. 1 depicts an exemplary embodiment of a refrigerant vapor compression system 10 suitable for use in a transport refrigeration system for refrigerating the air or other gaseous atmosphere within the temperature controlled cargo space of a truck, trailer, container or the like for transporting perishable / frozen goods. The refrigerant vapor compression system 10 is also suitable for use in conditioning air to be supplied to a climate controlled comfort zone within a residence, office building, hospital, school, restaurant or other facility. The refrigerant vapor compression system could also be employed in refrigerating air supplied to display cases, merchandisers, freezer cabinets, cold rooms or other perishable / frozen product storage areas in commercial establishments.

[0012]The refrigerant vapor compression system 10 is particularly adapted for operation in a transcritical cycle with a low critical temperature refrigerant, such as for example, but not limited to, carbon dio...

Abstract

A refrigeration system includes a compressor having a first stage (20a) and a second stage (20b); a motor (22) driving the compressor; a heat rejecting heat exchanger having a fan (44) drawing ambient fluid over the heat rejecting heat exchanger, the heat rejecting heat exchanger including an intercooler (43) and a gas cooler, the inter-cooler coupled to an outlet of the first stage and the gas cooler (41) coupled to an outlet of the second stage; a flash tank (70) coupled to an outlet of the gas cooler; a primary expansion device (55) coupled to an outlet of the flash tank; a heat absorbing heat exchanger (50) coupled to an outlet of the primary expansion device, an outlet of the heat absorbing heat exchanger coupled to the suction port of the first stage; and a controller (100) for implementing a pulldown mode, a control mode and a staging logic mode.

Description

BACKGROUND OF THE INVENTION[0001]Embodiments relate generally to refrigerant vapor compression systems and, more particularly, to temperature control logic for a refrigeration system.[0002]Refrigerant vapor compression systems are well known in the art and are commonly used for conditioning air to be supplied to a climate controlled comfort zone within a residence, office building, hospital, school, restaurant or other facility. Refrigerant vapor compression systems are also commonly used in refrigerating air supplied to display cases, merchandisers, freezer cabinets, cold rooms or other perishable / frozen product storage areas in commercial establishments.[0003]Refrigerant vapor compression systems are also commonly used in transport refrigeration systems for refrigerating air supplied to a temperature controlled cargo space of a truck, trailer, container or the like for transporting perishable / frozen items by truck, rail, ship or intermodal means. Refrigerant vapor compression syst...
