本人在进行冰柜修理工作中发现,冰柜故障多数是热力膨胀阀冰堵或脏堵,导致冰柜不能降温。要彻底排除这一类故障,只能是先对冰柜制冷系统进行彻底清洗排污,然后再进行日常修理,这样才能行之有效。然而目前生产的冰柜,这样做很不方便,不但要把系统中的制冷剂放掉,而且喇叭口接头处易造成泄漏或损坏,(图1所示),对此,我在其中增加了两只三通阀(如图2所示)。这种制冷系统为修理人员有效地解决了对系统进行清洗排污难的问题,具体优点以列表形式进行对比。
I was in the freezer repair work found that the majority of freezer failure is the thermal expansion valve ice blocking or dirty block, leading to freezer can not cool. To completely eliminate this type of failure, only the first freezer refrigeration system to thoroughly clean the sewage, and then carry out routine repairs, so as to be effective. However, the current production of freezers, which is very inconvenient, not only to let go of the refrigerant in the system, but also at the bell mouth joints can cause leakage or damage, (Figure 1), which, I added two Only three-way valve (shown in Figure 2). This refrigeration system for the repair staff to effectively solve the system cleaning difficult sewage problems, the specific advantages of a list of forms of comparison.
