In summer, many merchants will use the chest freezer, and some merchants who know it well will often defrost or deice it, but most of the time, merchants will use sharp weapons to deice it. This method can easily damage the evaporator without knowing it. When it is started again, the water will be sucked in by the pipeline rupture of the evaporator, which will cause serious ice blockage in the refrigeration system. Then the China Chest Freezer Factory will come and talk to you about how to deal with the following matters.
Many merchants replace the refrigerating oil by themselves. Basically, the glass injector is used by the merchants to inject the dehydrated refrigerating oil into the dried compressor through the process pipe. The transparent plastic (structure: synthetic resin, plasticizer, stabilizer and pigment) rubber hose is sleeved on the process pipe of the compressor in the cabinet and inserted into the prepared dehydrated refrigerating oil. The compressor is started and the refrigerating oil is sucked by itself.
However, many merchants don't know that air can't enter every operation when filling, and all ports need to be sealed with rubber plugs before all components in the wind cabinet are connected into a refrigeration system. Remove the air return pipe, capillary tube, evaporator, condenser (type: heat exchange equipment) and compressor, and bake them in an oven at 120℃ for 8h. After naturally cooling to room temperature in the oven, blow them off with high-pressure nitrogen, but before baking (explanation: baking things with fire), the compressor should pour out the refrigerant oil through the suction pipe or process pipe.
Merchants who have dismantled the capillary in the cabinet know that its return pipe is the most difficult to dismantle, but we can bake it back and forth with a blowtorch (explanation: bake something with a dry fire), heat it evenly, and blow it off with nitrogen.
