一、两个蒸发温度合用一个中间冷却器及其优点采用氨双级压缩制冷的冷藏库,对中间冷却器的布置有下列三种做法: 1.每台(组合式双级压缩机为每套)氨双级压缩机布置一个中间冷却器。这种做法的优点是:只要在压缩机低压缸吸入和中间冷却器蛇形管出液管上装设旁通阀,就能打二个蒸发温度中任意一个蒸发温度,因此操作比较方便,见图1。这种做法的缺点是:由于中 First, the two evaporation temperature combined with an intercooler and its advantages Ammonia two-stage compression refrigeration refrigerator, the intercooler arrangement has the following three practices: 1. Each (combined two-stage compressor for each set ) Ammonia bi-stage compressors are equipped with an intercooler. The advantage of this method is that it is convenient to operate any one of the two evaporation temperatures as long as the bypass valve is installed in the compressor low pressure cylinder suction and the intercooler serpentine outlet pipe. 1. The disadvantage of this approach is: due to
