双级压缩机以其降温速度快、耗电省等特点正被广泛地采用。同双级压缩机配套的中间冷却器是维持双级压缩制冷循环正常工作的必要设备。中冷器安装着各类大小阀门十几个之多,修理阀门、更换填料需要停机。有时供液电磁阀因使用不当或质量等原因造成供液失控,引起压缩机二级吸气过潮,也需要停机处理。这样中冷器就不能工作了。一般双级压缩机制冷的中、小型冷 Two-stage compressor with its cooling speed, power consumption and other characteristics are being widely used. Intercooler with dual compressor is the necessary equipment to maintain the normal operation of the two-stage compression refrigeration cycle. Intercooler installed a variety of sizes of valves as many as a dozen, repair valves, replacement of packing need to shut down. Sometimes for liquid solenoid valve due to improper use or quality of liquid caused by uncontrolled, causing the compressor two inspiratory too much, but also need to stop processing. This intercooler will not work. General two-stage compressor cooling medium and small cold
