定される。FIG. 3 shows a refrigeration cycle using a non-azeotropic mixed refrigerant,
The compressor 11, the condenser 12, the two gas-liquid separators 13, 14, the decompression device 15, and the cooler 16 are sequentially connected to form a closed loop, and the liquids separated by the gas-liquid separators 13 and 14 are separated. The refrigerant is decompressed by the thin tubes 17 and 18, and the cascade heat exchangers 19 and 20 for exchanging heat between the decompressed refrigerant and the return gas refrigerant from the cooler 16 and the gas refrigerant separated by the gas-liquid separators 13 and 14, respectively. It will be installed. In the cascade heat exchangers 19 and 20, the outer pipe 21 is used as a refrigerant supply passage from the compressor 11 as shown in FIG.
Further, it is a double-tube heat exchanger in which the inner tube 22 is formed in a coil shape using the refrigerant return passage from the cooler 16. The pitch P between the coils of the double tube heat exchangers 19 and 20 is set to be larger than the diameter D of the outer tube 21, and a space A is formed between adjacent outer tubes 21. Reference numeral 23 is a resin-made mounting stay having a large number of holes 23a formed at predetermined intervals as shown in FIG. 2, and is arranged on the inner peripheral side of the double pipe heat exchangers 19 and 20, and the holes 23a are A plurality of outer tubes 21 are secured to predetermined positions of the mounting stays 23 by flexible fastening members 24 (corresponding to cords made of synthetic resin in this embodiment). The mounting stay 23 is fixed to the bottom plate 5 of the refrigeration system.
