Refrigeration appliance with compressor operation - has several evaporators deiced on normal operation without influencing other evaporators

摘要

The refrigeration appliance, such as refrigerator or deep freezer has compressor operated refrigerating system. Two series connected evaporators are provided in the refrigerator circuit which may have compensation vessel between second evaporator and the compressor. The first evaporator is deiced without any thermal effect on second evaporator. The condenser (28) and the throttle (31) are bypassed by a pipe (39) with valve (40) closed on normal operation. The connecting pipe (33) between two evaporators (14, 18) has stop valve (34) which is open on normal operation. The connecting pipe (33) between two evaporators (14, 18) has stop valve (34) which is open on normal operation. The second throttle (42) is connected in parallel to this stop valve. A third throttle and third evaporator can be connected in parallel to the first evaporator (14) and first throttle (31).
