Abstract
A refrigeration system, wherein without providing a drier for removing the moisture entering the cycle, stable operation of the refrigeration system is made possible by setting the balanced moisture concentration of the refrigerant during operation to less than 350 ppm by relatively selecting the moisture permeations of the lines upstream and downstream of the compressor and by using a refrigerant with a higher saturated moisture concentration. Further, as the lubricating oil circulating in the freezing circuit mixed in the refrigerant, use is made of one with a saturated moisture concentration higher than that of the refrigerant.
