Air curtain cabinets are widely used in large supermarkets, convenience stores, fresh stores and fruit stores. Do you know how to maintain the air curtain cabinet? Here we summarize a few suggestions on how to maintain the air curtain cabinet.

1. The compressor and radiator of the air curtain cabinet should be cleaned regularly. The compressor configured for the air curtain cabinet has relatively large power and more heat dissipation. Since the heat dissipation effect is crucial to the stable operation of the compressor, it is best for the operator to clean it regularly once a month. We can use the brush to clean the dust and flocculent attached to the radiator.
2. During proofing time, the staff remember to pull down the curtain of the air curtain cabinet. Air curtain cabinets are equipped with hidden night curtains. After the store or supermarket operation, the staff pull down the curtain, which can minimize the loss of cold air in the freezer, so that the compressor downtime is long, the startup time is short, and the energy saving is saved.
3. Regularly clean the air curtain cabinet drain.

 

During the operation of the air curtain cabinet, it is inevitable that dust and foreign bodies will enter the suction vent. After a long time of operation, they will accumulate under the bottom plate, and foreign bodies will block the condensate drain. The condensate can not be discharged, and the dust will be blocked at the bottom of the air curtain cabinet, which will cause water seepage or overflow at the bottom of the cabinet. So we have to clean the drains regularly every month.

 

4. The goods placed on the bottom layer can not block the suction vents; The goods placed on the upper layer should not be piled too high to avoid blocking the back outlet. The cooling principle of the air curtain cabinet is that the air flow from the bottom suction tuyere to the back and top outlet to achieve a cold air heat exchange cycle. If the suction is blocked (or the outlet is blocked), it will hinder the air heat transfer cycle and affect the cooling effect.

 

Non-professionals shall not set the thermostat without permission.

The temperature controller is the automatic temperature control program of the air curtain cabinet, which includes the upper starting temperature, the lower stopping temperature, the upper and lower temperature difference, the defrosting time, the defrosting interval and so on. In general, factory Settings are the most reasonable and stable data. If the data is arbitrarily changed in order to lower the temperature, it will cause the compressor to not stop, the evaporator ice blocking and so on.

 

6. In order to safely start the air curtain cabinet, the temperature controller delays the start of the compressor. Every time the air curtain cabinet power switch is opened, the compressor does not start working immediately, but the compressor starts after a delay of three minutes. During the delay time, the snowflake sign on the upper left corner of the thermostat has been flashing; Three minutes later, the delay time is up, the snowflake sign is no longer blinking, and it becomes a steady state. At this time, the sound of the relay “snap” can be heard, and the compressor starts the cooling operation.

 

7. During daily use, the thermostat will shut down the compressor every four hours and allow the evaporator to automatically frost. Each defrosting time is 10 minutes. During defrosting time, the snowflake mark at the lower right corner of the thermostat disappears and the snowflake mark appears at the lower left corner. During the defrosting time, the temperature controller shows that the temperature rises to about 15 degrees, which is a normal phenomenon.

 

8. The rainy summer air has high humidity. The air curtain cabinet back outlet and top outlet will appear small water beads, which is a normal condensation phenomenon. We wipe it with a clean rag, and the condensation will soon disappear.

 

9. The compressor of the air curtain cabinet of the integrated machine is at the bottom of the machine, and the compressor has more heat dissipation. In order to ensure the normal operation of the compressor, the back of the air curtain cabinet must be 20-30 cm away from the wall, so as to facilitate circulation and heat dissipation. Otherwise, the compressor thermal protection will be caused, resulting in the compressor does not start. If the compressor does not start, we need to stop for 2 to 3 hours, wait for the compressor to cool down, find the red button reset key on the pressure controller next to the compressor, reset the pressure controller, and the compressor can restart.
