从事制冷工作的人员都知道制冷装置中有空气存在,对制冷柳的运行极为不利。如制冷装置中有10%的空气存在,将使制冷机的能力下降10%,电量浪费10%,冷凝温度和蒸发温度升高,降温困难,给操作带来一些不利的影响。因此,在制冷操作中防止外界空气的串入或及时排除系统中的空气,是一项重要的工作。制冷装置中的空气怎样排出!从那里才能有效地排除,是值得研究和探讨的,笔者
Refrigerators are aware of the presence of air in the refrigeration unit and are extremely unfavorable to the operation of the refrigeration liu. If 10% of the air in the refrigeration unit is present, the capacity of the refrigerator will be reduced by 10%, the power consumption will be 10%, the condensing temperature and the evaporating temperature will increase, and the cooling will be difficult, which will bring some unfavorable effects on the operation. Therefore, it is an important task to prevent the intrusion of outside air during the refrigeration operation or to timely remove the air from the system. How to remove the air from the refrigeration unit and effectively remove it from it is worth to be studied and discussed.
