Industrial chiller air into the refrigeration system how to do?Issuing time:2021-12-29 16:13 In the daily operation of industrial chiller, air is prone to enter the refrigeration system. Because the low temperature in the refrigeration system will not condense the air with liquid, but will affect the heat dissipation of the condenser, leading to the increase of condensation pressure, and causing the normal operation of the industrial chiller. Therefore, the air in the industrial chiller needs to be discharged in order to maintain the normal operation of the industrial chiller. The correct way is to close the reservoir outlet valve or condenser outlet valve; Start the compressor, the refrigerant in the low pressure section into the condenser or liquid storage device; Stop the machine when the low pressure system pressure drops to a stable vacuum state; Loosen the bypass hole plug of the exhaust stop valve, turn around half a circle, and the exhaust valvestem makes the valve into a three-way shape, so that the high pressure gas escapes from the bypass hole. Block the exhaust air flow with the palm of your hand. When the hand feels cool and there is oil mark on it, it means that the air has been basically exhausted. Tighten the screw plug, reverse the exhaust valve stem, and close the bypass hole. It should be noted that each time the industrial chiller should not be too long, and it can be carried out for 2 to 3 times continuously to avoid wasting refrigerant. If the condenser or reservoir is equipped with a spare stop valve at the top, air can be released directly from the valve. |
