Convenience store refrigerators are essential items for chain convenience stores and shopping malls, suitable for refrigeration, preservation, frozen products or alcoholic beverages. So if the convenience store freezer is not cold, it will seriously endanger the food hygiene and safety inside the cabinet. So what exactly causes convenience store refrigerators to not be cold? Let's ask technical professionals together below. Analysis of the initial reasons:

1. The ultra-high pressure export buffer tube inside the refrigeration compressor is broken, or the screw that fixes this tube is loose, causing the air conditioning tube to not exhaust and the bottom pressure tube to not breathe. Therefore, although the refrigeration compressor is running, it does not cool.

2. The refrigeration unit leaked, and all the refrigerant ran out. Although the refrigeration compressor is running, there is no heat released by the refrigerant in the system software, so the ambient temperature inside the refrigerator does not drop.

3. Blockage in capillaries prevents refrigerant from entering the evaporator of the air conditioner to dissipate heat, and the ambient temperature inside the freezer does not decrease.

How to eliminate those common faults?

1. Cut open the shell, replace the cache tube, or tighten the screws.

2. First, identify the location of the system software leakage, perform welding, pressure measurement, and vacuum pumping, and then add refrigerant to a sufficient amount. Generally, the standard is based on the air conditioner evaporator being frosted or the ambient temperature inside the refrigerator exceeding the rated value.

3. Blockages in capillaries or air dryers can cause both the inlet and outlet to become hot, so they should be removed to eliminate them. If those are not the key reasons, it is very likely that there is a malfunction in the internal structure of the refrigerator, such as a lack of refrigerant or a broken refrigeration compressor.
