Title: Hot gas defrost refrigeration system
Inventor: LAMMERT PAUL F
IPC: F25D21/06
Filed: 1991-02-25
Abstract: A hot gas defrost refrigeration sys-tem has a compressor, a condenser, and an evaporator, interconnected by fluid passage means and incorporating valve means to cause refrigerant to flow se-quentially through the compressor, con-denser, and evaporator to the compressor during the refrigeration cycle. Refriger-ant flow during the defrost cycle is from compressor to evaporator through the condenser to the compressor. The refri-geration system includes defrost passage means, including valve means, connect-ing the evaporator outlet to the condenser inlet and connecting the condenser outlet to the compressor inlet. A vessel is pro-vided which combines the functions of receiver during refrigeration and super-heater during defrost. During refrigera-tion liquid refrigerant flows from the condenser through the superheater/re-ceiver to the evaporator. During defrost, the defrost passage means directs vapo-rous refrigerant from the evaporator through the superheater/receiver to the compressor. The compressor discharge passage to the evaporator includes a superheat passage in heat exchange relationship with the superheater for transferring heat from com-pressor discharge refrigerant to compressor suction refrigerant during the defrost cycle. The condenser is utilized as a reevapora-tor during defrost and the superheater/receiver exchanges heat between compressor inlet and suction refrigerant to enhance sys-tem operation during the defrost cycle.
