Abstract
A packaged, pumped liquid, recirculating refrigeration system with charges of 10 lbs or less of refrigerant per ton of refrigeration capacity. The compressor and related components are situated in a pre-packaged modular machine room, and in which the condenser is mounted on the machine room and the evaporator is close coupled to the pre-packaged modular machine room. Prior art large receiver vessels may be replaced with a single or dual phase cyclonic separator also housed in the pre-packaged modular machine room.
Claims6
A refrigeration system comprising:
- a refrigerant condenser;
- and
- a transportable pre-fabricated modular refrigeration machine room sized to allow entry of a technician therein for servicing, said transportable pre-fabricated modular refrigeration machine room containing:
- a vapor/liquid separation structure configured to be connected to an outlet of an evaporator via refrigerant line;
- a refrigerant compressor connected to an outlet of said vapor/liquid separation structure via refrigerant line and connected to an inlet of said condenser via refrigerant line;
- a collection vessel connected to an outlet of said refrigerant condenser via refrigerant line;
- refrigerant line connecting an outlet of said collection vessel to an inlet of said vapor/liquid separation structure;
- wherein said vapor/liquid separation structure has an outlet that is configured to be connected via refrigerant line to an inlet of an evaporator;
- said refrigeration system further comprising refrigerant in an amount of less than six pounds of refrigerant per ton of refrigeration capacity.
