【摘要】 通过对混合工质的研究、空调压缩机的改装、油分离器以及节流制冷器的设计,研制了一台闭合循环节流制冷机。由于采用了油润滑压缩机,因而该制冷机具有高可靠性;由于该制冷机的制冷部件(J-T制冷器)与运动部件(压缩机)采用柔性连接,因而该制冷机提供了低振动的冷源。更多还原

【Abstract】 A closed J-T refrigerator has been developed, This refrigerator consists of a normal oil-lubricated air-condition compressor, an oil-separator and a J-T cooler, And it works with mixed refrigerant,As the cold finger is connected to the compressor with flexible construct and the refrigerator works with new efficient and unique mixed refrigerant,this refrigerator can provide efficient refrigeration with low noise and low vibration,This paper discusses how to develop the unique refrigerator and introduces several tests on this refrigerator.更多还原
