1. When air is released by the air separator, the air return valve of the air separator is placed in the normally open state to reduce the pressure of the air separator to the suction pressure, and the other valves should be closed.
2. Properly open the mixed gas intake valve to allow the mixed gas in the industrial chiller refrigeration system to enter the air separator.
3. Micro-opening the liquid supply valve to allow the refrigerant to throttle into the air separator to vaporize and absorb heat, and to cool the mixed gas.
4. Connect the rubber hose for the air valve connection so that one end is inserted into the water in the water container. When the refrigerant in the mixed gas is cooled to ammonia, the bottom of the air separator is frosted, and the air valve can be slightly opened to discharge the air through the water container. If the bubble rises in the water, it has a circular shape and no volume change. If the water does not rise, the water temperature does not rise, and the air is released. In this case, the opening of the air release valve should be appropriate.
5. The refrigerant in the mixed gas is gradually condensed into a refrigerant liquid and stored in the bottom. The liquid level height can be seen from the frosting condition of the outer casing. When the liquid level reaches 12, the liquid supply throttle valve is closed and the liquid return throttle valve is opened. The bottom refrigerant liquid is returned to the air separator to cool the mixed gas. After the frost layer of the bottom layer is about to melt, close the liquid return throttle valve to open the liquid supply throttle valve.
6. When stopping the air release, first close the air valve to prevent the refrigerant from leaking out, and then close the liquid supply throttle valve and the mixed gas intake valve. In order to prevent the pressure in the air ventilator from rising, the return air valve should not be closed.
