Freezer With Heated Floor And Refrigeration System Therefor
US Patent:
5584190, Dec 17, 1996
Filed:
Sep 25, 1995
Appl. No.:
8/533616
Inventors:
Ronald A. Cole - Champaign IL
International Classification:
F25B 2700, F25D 1300
US Classification:
62260
Abstract:
A freezer box comprising an enclosure resting on soil, the soil having a tendency to freeze from the cooling effect of the freezer positioned above. Pipes, through which a warm fluid flows, thereby being cooled, buried under the freezer enclosure for warming and preventing the freezing of the sub-freezer soil. A refrigeration system having a condenser for receiving refrigerant vapor and condensing it to a warm liquid. An evaporator for producing cooling by evaporating the liquid refrigerant condensed by a condenser. A pipe for conveying the flow of warm liquid refrigerant from the condenser to the evaporator and a heat exchanger positioned to exchange heat between the flow of cool fluid, having warmed the soil under the freezer, and the flow of warm liquid refrigerant enroute through the pipe from the condenser to the evaporator, thereby warming the flow of fluid and cooling the flow of liquid refrigerant.

International Classification:
F25B 4302
US Classification:
62 84
Abstract:
The invention resides in improvements to refrigeration systems which rely on circulation of refrigerant gas through compression and expansion phases, and thereby discharging heat from a fluid to be cooled. The invention includes a subcooler (38) in the refrigerant loop, downstream of the refrigerant condenser (34) and a gas trap (36) between the condenser (34) and the subcooler (38), that assures temperature drop in the subcooler (38). The invention also comprehends a shut-off valve (44) between the compressor and the heat source heat exchanger (28). The invention further includes a high capacity-to-volume oil to air heat exchanger (48), for cooling the lubricating oil in the oil loop (26). Preferred refrigerant is ammonia. Incorporating the above improvements into refrigeration systems enables an overall reduction in system sizing.
