四温区温度可调制冷装置的制冷系统

A refigeration system with adjustable four-temperature-zone used in refrigeration unit

在深冷区、冷冻区、冰温区及冷藏区蒸发器两端并联单向电磁阀实现三级分流以控制和分配制冷量,实现四温区温度可调,形成多种组合节能运行模式或延伸功能,同时减少主机开停机次数达到节能目的。

In order to control and distribute cooling capacity, one -way solenoid valves were parallelly equipped to the evapo- rators in cryogenic, freezing,icy and refrigerating temperature zones to achieve mass flow rate distribution at three level. The te- peratures in four zones were designed to be ajustable, and then multiple energy - saving operation patterns or extended services could be obtained. Besides, the on - off times of compressor were reduced to conserve energy.
