摘要
采用风冷冷凝器的大型制冷系统在冬季运行时,由于冷凝器所处的环境温度较低,会导致冷凝压力过低,从而影响到正常供液和系统的正常工作。这可以通过减小传热温差、减小有效冷凝面积、减小冷凝风量以及热气旁通的方法进行改善和解决。
when a large refrigeration system with air- cooled condenser runs in winter, since the ambient temperature is low, the condensing pressure of the system will be unusual low, affects the system feeding and operation.Thls problem can be solved by reducing the temperature difference of heat - transfer, the effective area of the condenser, and the volume of the air and/or hot gas by - pass.
