Use of time longer supermarket freezer refrigeration systems are generally part of the accumulation of air, if this situation will not be resolved in time to increase the efficiency of the compressor, it will result in long-term accumulation of air cooling system failure. Here we will introduce detailed supermarket freezer refrigeration systems air discharge method.

Combination supermarket chest freezer

1. Close reservoir valve or the oil cooler of the valve.
2. Start the compressor, the low stage discharge refrigerant within the instrument or to the cold reservoir in.
3. When the low pressure section to stabilize vacuum compressor shut down.
4. The exhaust gas shutoff valve counter-clockwise to fully open state, unscrew the drain valve bypass valve orifice passage only Prather, air shutoff valve is rotated to the "three links" state.
5. The high-pressure gas discharged from the bypass passage hole, when the hand is feeling chilly or if you observe the oil droplets to immediately shut off the exhaust bypass valve hole passage, removal of air operation is complete.
6. The exhaust gas shutoff valve is rotated to the "three links" state, exhaust air supermarket freezer refrigeration system operation is complete.

If you could not find a single operation when operating the air drained, repeat the word until 1-2 before the air removal is completed in operation.
