3.往复式制冷压缩机往复式制冷压缩机应用极为广泛,近年来在国标制冷机领域中仍然占有绝对的优势,但也受到旋转式机型的挑战。目前该型机器的主要研究动向仍然是力求提高其热效率。由于加工精度的提高,新材料的应用,机器向小型、轻量发展。为了节能,机器的能量调节档次增多,使之调节灵活。半封闭式压缩机可作到
Reciprocating refrigeration compressors Reciprocating refrigeration compressors are widely used in recent years in the field of GB refrigerators still occupy an absolute advantage, but also by the challenges of rotating models. At present, the main research trend of this type of machine is still trying to improve its thermal efficiency. Due to the improvement of machining accuracy, the application of new materials, the machine to small, lightweight development. In order to save energy, the energy of the machine to adjust the grade increase, make it flexible regulation. Semi-hermetic compressors are available
