The air separator is connected to a suction pipe industrial chiller system with low evaporation temperature, inlet evaporative load is stable in the loop and sent to the gas-liquid separator tube, to prevent the air in the discharge process due to improper operation caused wide liquid throttling refrigeration compressor, wet compression produced or cylinder accident. For example, food storage generally has three evaporation temperature loop, namely for frozen food processing for frozen food cold storage system, -33 C -28 C -15 C system and for the system of ice, ice storage and storage of fresh food. In the three loop evaporation temperature is the lowest -33 C system, but due to seasonal freezing processing is very strong, this is not the year evaporation loop, so the non condensable gas exhaust pipe is not connected to the loop system -28 C low temperature and annual work, should be pumping pipe access this system.
Because of the large number of equipments, the air emission becomes more and more complicated and the labor intensity is large. Therefore, the automatic air separator also shows a unique advantage, automatic air separator is a vertical air separator with automatic control components. It is the working principle of high pressure liquid in liquid ammonia through the solenoid valve, evaporation chiller cooling coil into the air separator by thermal expansion throttling after Fujian in saturated gas from the exhaust pipe to discharge, and the liquid supply coil by thermal expansion to 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 When the temperature is up to 8 DEG C, the temperature controller moves, so that the electromagnetic valve is closed. Automatic air separator and stop by the compressor control. As long as the operation of the compressor of the solenoid valve open, began to work; the compressor stops, the solenoid valve is closed automatically stop working air separator at low temperatures, in order to avoid the loss of cooling capacity, the shell shall be insulated. In order to ensure that the condensate in the air separator shell smoothly enters the high pressure liquid storage device, the installation position must be higher than the upper surface of the upper surface of the liquid storage tank body 600mm above.
