1. Close the outlet valve of the accumulator or the outlet valve of the condenser;

2. Start the compressor and collect the refrigerant in the low-pressure section into the condenser or accumulator;

3. After the low pressure system pressure drops to a stable vacuum state, the machine will stop;

4. Loosen the screw plug of the bypass hole of the exhaust shut-off valve and turn it about half a turn. Block the exhaust airflow with the palm of your hand. When the hand feels cold air and oil stains on your hand, it means that the air has been basically exhausted. Tighten the screw plug, reverse the exhaust valve stem, and close the bypass hole.

5. It should be noted that the time of each deflation should not be too long, and it can be performed continuously for 2 to 3 times to avoid wasting refrigerant. If there is a backup shut-off valve on the top of the condenser or accumulator, the air can also be discharged directly from the valve.

2. Operation steps of venting industrial chiller of refrigerant refrigeration system

1. When using an air separator to discharge air, place the return valve of the air separator in a normally open state to reduce the pressure of the air separator to the suction pressure, and all other valves should be closed.

2. Properly open the mixed gas inlet valve to allow the mixed gas in the chiller refrigeration system to enter the air separator.
