The supermarket freezer turns off the power of the freezer after the business is closed to save electricity. That is, in order to save energy, more electricity is consumed when it is open for business the next day. Opening the freezer frequently without waiting for the freezer to start for a period of time will increase the probability of freezer failure, so know the freezer's uptime and cooling time.

(1) The supermarket freezer starts for a period of time, and starts after about 4-5 minutes. Evaporator frosting is fine. This situation is completely normal. Hourly downtime is undetermined due to freezer restrictions. 2-6 downtimes per hour are generally considered normal. The above situation is normal, but somewhat more. The situation can be improved by installing a plastic tube in the capillary temperature detection section of the thermostat to increase thermal resistance. If the curtain cabinet freezes faster, you can remove the thermostat and adjust the upper limit of the temperature control.

(2) After the supermarket freezer is started, it will stop for a few seconds to tens of seconds, and start after a few minutes. It will stop by itself, repeat work, and start frequently. And the freezer can't be cooled. This state is mostly due to partial damage to the winding insulation, resulting in a short circuit in the turn, but it is not enough to break the fuse. Followed by mechanical defects and wear of cooperative surfaces, increased compressor power, and increased current. If the current exceeds the specified value, the starting relay cannot be released normally after being absorbed, so the current is more than 5 times larger than the normal operating current, and the thermal maintenance relay will actively maintain and cut off the circuit for about 10 seconds, reactivate after a few minutes, and start frequently.

In addition to ice plugs, refrigerant leaks, the problem should be dirty plugs. In repairs, the fleece sewn tube is cut to 5-10em and the compressor is filled with nitrogen or freon steam for comfort. If uncomfortable, replace the capillary. The replacement capillary should be as equal as possible to the original tube standard, length. Refrigerator, showroom refrigerant leakage problem, if not completely leaked, it can be refrigerated. The effect is low, the evaporator is partially frosted or frosted, and the condenser shows some warmth.

After the businessman understands the principle of opening and closing of refrigerators in supermarkets, how much do they know about refrigerators? In fact, the principle of other commercial freezers is almost the same, so we can't lose more power in pursuit of instant power. It is also very troublesome in supermarket freezers, because the freezer is out of time and will delay a lot of things, so we need to use the freezer objectively .
