Example Embodiment
[0026] Example 1: In the refrigerant cycle system of A above, the membrane evaporation separation device 14 has a permeability of 1*10 -2 --5*10 -4 L / min.cm 2 .Pa sintered metal hollow tube separation membrane and a copper shell encapsulating the metal hollow tube separation membrane. The cavity between the shell and the metal hollow tube separation membrane is a refrigerant evaporation chamber. The two ends of the device are directly equipped with refrigerant liquid inlet and outlet ports.
Example Embodiment
[0027] Example 2: In the refrigerant cycle system of A above, the membrane evaporation separation device 14 has a permeability of 1*10 -2 --5*10 -4L / min.cm 2 .Pa ceramic tube separation membrane and a copper shell encapsulating the ceramic tube separation membrane. The cavity between the shell and the ceramic tube separation membrane is a refrigerant evaporation chamber. At both ends of the separation membrane, direct cooling is installed The agent liquid enters and discharges from the outlet.
Example Embodiment
