The composition of the freezer:

1. compressor 2. condenser 3. evaporator 4. drying filter 5. expansion throttle valve

After a long period of use, we have to regularly maintain and maintain the freezer to ensure that the freezer can operate normally without affecting the cooling effect and causing machine failure.

1. Maintenance and maintenance of the compressor

(1). Oil change: The unit must change the refrigeration oil once a year, or decide whether it needs to change oil in advance according to the actual situation or oil analysis.

(2). Oil change filter: When the oil pressure drops by 30% or the unit is operated for half a year, the oil filter is replaced. Also check for any metal shavings in the filter to confirm the internal wear of the unit.

(3). Fasten the slide valve: Check and tighten the pipe connection of the slide valve.

(4). Check the coil: Check the solenoid valve coil of the spool valve.

2. Maintenance and maintenance of the evaporator and condenser

(1). Check the flow of chilled water and cooling water.

(2). Check the water flow switch of chilled water and cooling water.

(3). Check the charge of the refrigerant.

(4). Check the screws of the evaporator and condenser water chamber and end cover. Confirm that there is no water leakage.
