The air separator suction pipe should be connected to the industrial chiller system in the low evaporation temperature, evaporation loop load is stable and sent to a gas-liquid separation equipment of the air inlet pipe to prevent in air discharge process for liquid throttle wide improper operation, leading to the refrigeration compressor wet compression or shock cylinder accident. For example, food storage generally have three evaporation temperature loop, namely for frozen food processing - 33 degrees Celsius system, for frozen food cold storage - 28 DEG C system and used for ice making, ice storage and fresh food storage of - 15 DEG C system. In the three loop evaporation temperature minimum is 33 degrees Celsius system, but due to the freezing processing seasonal very strong. The evaporation loop and not perennial of, so non condensable gas pumping pipe cannot access the loop - 28 DEG C system low temperature and perennial work should be pumping tracheal this system.
In large scale ammonia refrigeration equipment due to more equipment, air emissions becomes very cumbersome, labor intensity is large. Therefore, the automatic air separator also shows the unique advantages, automatic air separator is the use of vertical air separator with automatic components. Its working principle is a high pressure liquid storage of liquid ammonia through the electromagnetic valve, through the thermal expansion of Fujian throttling into air separator of chiller cooling coil heat absorption and evaporation, saturated gas from the exhaust pipe exhaust, and coil for the liquid volume by thermal expansion reading control. The barrel of mixed gas continuously into the air separator, which is condensed into liquid ammonia and ammonia by gravity flow back into the reservoir, non condensable gas accumulation in the upper barrel body, and the aggregate amount of non condensable gas increased "pressure is gradually increased, enter the amount of mixed gas will decrease that is to say, to reduce the amount of ammonia, the ammonia liquid coil in the continuous evaporation refrigeration, cooling capacity will be used to absorb ammonia condensation, not dirty gas to absorb heat" caused by non condensable gas temperature decreases, when the temperature dropped to -12 DEG C, the temperature controller is arranged on the action of the air separator the electromagnetic power on the Fujian, non condensable gas discharge system, the air separator pressure decreases in condensing temperature under the mixed gas influx of air separator to increase the temperature, when the temperature A 8 degree rise to a temperature controller action 'so that the solenoid valve is closed, the first purge process will end. Automatic air separator and stop the compressor control. As long as the operation of the compressor electromagnetic valve open, began to work; stopping the compressor, electromagnetic valve closed stop automatic air separator at low temperature work, in order to avoid the loss of cooling capacity and the shell should be to conduct heat treatment. In order to ensure that the condensate liquid in the air separator is smoothly into the high pressure reservoir, its installation position must be higher than 600mm above the surface of the tank body.
