METHODS AND DEVICES TO PREVENT FLUID MIGRATION IN A REFRIGERATION SYSTEM DURING AN OFF CYCLE

摘要

Embodiments to prevent Off Cycle fluid migration in a refrigeration system are described. The embodiments described herein allow a fluid, such as oil from a crankcase sump of a compressor of the refrigeration system, to flow into an anti-fluid migration apparatus positioned in-line along a suction line of the refrigeration system. The fluid can be accumulated in the anti-fluid migration apparatus. The accumulated fluid may form a fluid flow barrier to prevent Off cycle refrigerant migration in the suction line.

1. A refrigeration system comprising:
a container of the refrigeration system configured to contain a fluid with a fluid level plane when the refrigeration system is in an Off cycle of the refrigeration system; a refrigerant line; a trap positioned in-line along the refrigerant line, the trap including a flow passage, at least a section of which is positioned lower than the fluid level plane in the container; and a conduit in fluid communication with the flow passage and the container; wherein the conduit is configured to allow fluid communication between the container and the flow passage of the trap when the refrigeration system is in an off cycle.
