在制冷系统中,使用蒸发器的目的是为了从周围环境中吸取和带走热量,它的移热能力与其内外的很多方面有关。这里仅论述一下如何对蒸发器进行除霜的方法。当蒸发器在冻结温度下运行时,霜层会越来越厚,严重地影响了蒸发器的工作效率,要想保持其工作效率,就必须对蒸发器进行除霜。在制冷系统中,有许多除霜方法,每种方法都各有其利弊,下面就以高压气体为除霜介质进行一下讨论。本文提到了几种常用的除霜 In refrigeration systems, the purpose of the evaporator is to draw and remove heat from the surrounding environment, and its ability to remove heat is related to many aspects of its internal and external aspects. Here only discusses how to defrost the evaporator method. When the evaporator is operating at a freezing temperature, the frost layer will get thicker and thicker, seriously affecting the efficiency of the evaporator. In order to maintain its working efficiency, the evaporator must be defrosted. There are many defrost methods in refrigeration systems, each of which has its own advantages and disadvantages, and is discussed below with high-pressure gas defrosting media. This article mentions several commonly used defrosting
