不凝性氣體對鹽水機制冷循環(huán)的影響及處理對策：這兒所說的不凝性氣體，是指在冷凝壓力下不能冷凝為液體的氣體。不凝性氣體通常積存于工業(yè)冷水機冷凝器和貯液器上部，因為它不能通過冷凝器或貯液器內(nèi)的液體有些的液封往下傳遞。
The effect of non condensing gas on the refrigeration cycle of brine machine and the treatment strategy: the non condensing gas mentioned here refers to the gas which can not be condensed into liquid under the pressure of condensation. Non condensable gases are usually stored in the industrial chiller and the upper reservoir, because it can not through the condenser or the reservoir liquid inside some of the liquid seal is passed down.
不凝性氣體的存在將使冷凝器內(nèi)冷凝面積削減，冷凝壓力升高，致使制冷壓縮機排氣壓力、溫度升高，壓縮比功添加，制冷系數(shù)降低，制冷量削減。那么鹽水機制冷體系中不凝性氣體來源于哪里呢？這兒舉例說明，比方說在體系檢修時帶入的空氣，有些潤滑油、制冷劑發(fā)生的分化，制冷壓縮機負壓時低壓有些滲透進來的空氣等。
The presence of non condensing gas will reduce the condensation area of the condenser, the condensation pressure is increased, the exhaust pressure of the refrigeration compressor, the temperature is increased, the compression ratio is increased, the coefficient of refrigeration is decreased, and the cooling capacity is reduced. So where is the non condensing gas from the salt water chiller system? Here for example, for example, when the system is brought into the air, some of the oil, refrigerant differentiation, refrigeration compressor when the pressure of low pressure some penetration into the air, etc..
而咱們在實踐應用中，是能夠采納一些相應的措施削減不凝性氣體的影響：
In practical application, we can adopt some measures to reduce the effect of non condensing gas:
1、比方小型分體式鹽水機在設備時，靠室外機內(nèi)原有的制冷劑壓力掃除銜接管路中的不凝性氣體；
1, for example, small split type brine machine in the equipment, by the outside of the original refrigerant pressure to eliminate the convergence of the pipeline in the non condensing gas;
2、給工業(yè)冷水機制冷體系沖灌制冷劑之前，必須先進行抽真空處理；
Before the 2, industrial chiller refrigeration system to make refrigerant must be washed, vacuum treatment;
3、給中、大型冷庫制冷體系中加裝空氣分離器，定時由空氣分離器掃除不凝性氣體；
3, to the medium and large cold storage refrigeration system installation of air separator, the timing of the air separator to remove non condensing gas;
4、在一些中央空調(diào)體系中，因為運用的鹽水機是在高真空度下作業(yè)，如溴化鋰吸收式制冷機、運用R123的離心式制冷機等，因而，在體系中加裝抽氣設備，及時抽出鹽水機中的不凝性氣體，保持制冷體系的高正空度。
In 4, some of the central air-conditioning system, because the saline water machine is the use of homework in high vacuum condition, such as the use of R123 type lithium bromide absorption refrigerating machine, centrifugal refrigeration machine, therefore, pumping equipment installed in the system, timely extraction of non condensable gas in the saline water machine, the refrigeration system to keep high empty.
