三、制冷剂管路的附件 1.液管 1.1 液体—吸气热交换器它是使液体制冷剂过冷而吸入气体过热的装置。下面叙述采用它的四个原因以及在每种用途中的最佳位置: 1.把液体制冷剂过冷用来补偿液管过分的压降,位置靠近冷凝器。在R22单级用途中,不推荐加液体-吸气热交换器,因为吸气的过热必须受到限制,以免压缩机受到过热。但是当它们被用在防止液体带进压缩机的地方,吸气的过热度应被限制在高于饱和温度11℃。设计成限制
Third, the refrigerant pipe fittings 1. Liquid pipe 1.1 Liquid - suction heat exchanger It is the liquid refrigerant is too cold and inhaled gas overheating device. Here are four reasons for using it and the best location for each application: 1. To subcool the liquid refrigerant to compensate for excessive pressure drop in the liquid pipe, close to the condenser. In R22 single-stage use, it is not recommended to add a liquid-suction heat exchanger as the inspiratory overheating must be limited to prevent the compressor from overheating. However, where they are used to prevent liquids from entering the compressor, the degree of superheat of the inspiratory air should be limited to 11 ° C above the saturation temperature. Designed to limit
