How to vent the industrial chiller of the 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 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.
3. Slightly open the liquid supply valve to throttle the refrigerant into the air separator to vaporize and absorb heat to cool the mixed gas.
4. Connect the rubber hose used for the air release valve interface and insert one end into the water in the water container. When the refrigerant in the mixed gas is cooled into ammonia liquid, frost will form on the bottom of the air separator. At this time, the air valve can be slightly opened to discharge the air through the water container. If the bubbles are round in the process of rising in the water and there is no volume change, the water is not turbid and the water temperature does not rise, then air is released. At this time, the opening of the air release valve should be appropriate.
5. The refrigerant in the mixed gas is gradually condensed into refrigerant liquid and accumulated at the bottom. The liquid level can be seen from the frosting of the shell. When the liquid level reaches 12, close the liquid supply throttle and open the liquid return throttle. The bottom refrigerant liquid is returned to the air separator to cool the mixed gas. When the bottom frost layer is about to melt, close the liquid return throttle valve and open the liquid supply throttle valve.
6. When stopping the air release, first close the air release valve to prevent the refrigerant from leaking out, and then close the liquid supply throttle valve and the mixed gas inlet valve. In order to prevent the pressure in the air release device from increasing, the return valve should not be closed.
