在制冷系统中,制冷剂(制冷工质)不断循环,通过本身的状态变化来实现制冷。目前制冷剂种类繁多,但大部分制冷剂,对大气臭氧层造成一定破坏,继而产生温室效应。随着社会科学技术的发展,现在人们普遍采用新型“绿色”制冷剂R600a替代以往的制冷剂,由于R600a制冷系统技术含量要求很高,下面就它的特性、制冷原理、操作维修工艺及注意事项做详细介绍。
In a refrigeration system, the refrigerant (refrigerant) circulates continuously, and the refrigeration is realized by the change of its own state. At present, there are many types of refrigerants, but most refrigerants cause certain damage to the atmospheric ozone layer, which in turn causes the greenhouse effect. With the development of social science and technology, people now generally adopt the new “green” refrigerant R600a instead of the previous refrigerant. Due to the high technical requirements of the R600a refrigeration system, its characteristics, refrigeration principle, operation and maintenance technology and Precautions to do a detailed introduction.
