To make a successful refrigerated display cabinet, it is necessary to make full and reasonable use of the unique space; Complete the practical function of displaying goods, beautiful and novel appearance, attract attention, and give people a good impression; Comply with merchant CI requirements. For a variety of display purposes of the refrigerator, the overall structure of the refrigerator is all detachable and removable parts, without using any glue materials, a screwdriver can complete the disassembly of the entire refrigerator, convenient disassembly, transportation, etc.

However, most of them are due to the longer use time of the refrigerator, resulting in aging or damage of parts, and the condensation in the refrigerator to form a loop, resulting in leakage of the refrigerator, in addition, the refrigerator in the handling of vibration caused by components collision, wire insulation layer damage may also cause leakage.

The phenomenon of leakage of temperature controller is: when the hand contacts the box, there is a numb inductance, but the compressor operation and the cooling in the box are normal. Because most of the thermostat of the island cabinet is installed on the inner wall, the temperature change in the cabinet will cause condensation around the thermostat. When condensate water flows into the thermostat, the resistance value between the thermostat electrical contact and the cabinet decreases, resulting in the cabinet being charged. We can eliminate these problems by regularly defrosting, often wiping the water in the refrigerator, preventing condensation from flowing into the thermostat and other measures. At the same time, pay attention to clean the temperature controller bakelite frame and the surrounding dirt, because the dirt will also produce leakage after moisture absorption.

Of course, we still need to often do a good job of single air refrigerator maintenance, so that there are fewer such problems, so that you get the best benefit.

The fault performance of moisture-proof wire leakage is that after the power is switched on, the start overload protection relay is frequently on and off, the compressor cannot be started, the cabinet is charged, and the numbness inductance is in contact with the hand, which is generally more common in the refrigerator with a long service life. At this time, we can use an insulating sleeve to cover the moisture-proof wire, and it is best to remove the old wire and replace it with a new rubber insulated wire.

The fault of compressor leakage is generally due to the long use time of the air cabinet around the island, which makes the insulation layer of the motor winding aging and falling off, causing leakage.

Check whether the insulation layer of the winding lead is damaged, resulting in bare steel wire and leakage caused by contact with the housing. If the above phenomenon exists, the damaged part can be wrapped with polyester film to avoid direct friction with the housing. If the insulating layer of the enameled wire is found to be off, it should be removed and re-dipped or the motor replaced.

4. After the induction leakage dual air refrigerator is started, if the cooling and control components in the cabinet are normal, but there is a numb electric feeling when touching the cabinet by hand, it indicates that there is induction leakage in the refrigerator. The reason for this is generally because the control line of the refrigerator compressor and the lighting line in the refrigerator are passed between the cabinet shell and the inner wall, if the wire insulation aging, the refrigerator has no reliable ground wire, when the hand touches the cabinet, it will produce numb inductance. If the neon bubble is lit up with the test pen, it indicates that there is a serious induced leakage in the refrigerator.
