The evaporator is provided with an inlet and an outlet; the condenser is provided with a condensation cavity, a gas inlet, a gas outlet and a liquid outlet; a molecular sieve membrane is disposed in the condensation cavity; one end of the first connecting pipe is connected to the outlet and the other end to the gas inlet; one end of the second connecting pipe is connected to the liquid outlet and the other end to the inlet; one end of the third connecting pipe is connected to the gas outlet and the other end to the inlet.

We claim: 
     
         1 . A refrigerating apparatus applied to an air conditioner, comprising:
 a refrigerant disposed in a pipeline of the refrigerating apparatus, the refrigerant comprising at least one of R600A, R417A, R410C or R407C;   a depressurization gas disposed in the pipeline of the refrigerating apparatus, the depressurization gas comprising at least one of hydrogen or helium;   an evaporator provided with an inlet and an outlet;   a condenser provided with a condensation cavity, a gas inlet, a gas outlet and a liquid outlet, wherein a molecular sieve membrane is disposed in the condensation cavity between the gas inlet and the gas outlet, and the molecular sieve membrane is configured to separate a mixed gas composed of the refrigerant and the depressurization gas;   a first connecting pipe having one end connected to the outlet and the other end to the gas inlet;   a second connecting pipe having one end connected to the liquid outlet and the other end to the inlet;   a third connecting pipe having one end connected to the gas outlet and the other end to the inlet;   a blower device communicated with the first connecting pipe and configured to introduce the mixed gas into the condensation cavity;   wherein the refrigerating apparatus has a system pressure set to be greater than a saturation pressure of the refrigerant at 40° C., and   a housing provided with a first installation space located at an inner side of a wall and a second installation space located at an outer side of the wall, the evaporator being installed in the first installation space, and the condenser being installed in the second installation space.   
     
     
         2 . The refrigerating apparatus according to  claim 1 , wherein a port of the third connecting pipe stretches into the second connecting pipe and protrudes beyond an inner wall of the second connecting pipe. 
     
     
         3 . The refrigerating apparatus according to  claim 1 , wherein the second connecting pipe comprises a liquid storage section comprising a plurality of U-shaped pipes. 
     
     
         4 . The refrigerating apparatus according to  claim 1 , wherein the refrigerating apparatus further comprises a heat dissipation device configured to dissipate heat from the condenser. 
     
     
         5 . The refrigerating apparatus according to  claim 1 , wherein the heat dissipation device comprises a cooling water pipe wound around the outside of the condenser. 
     
     
         6 . The refrigerating apparatus according to  claim 1 , wherein the system pressure of the refrigerating apparatus is set to be twice the saturation pressure of the refrigerant at 40° C. 
     
     
         7 . The refrigerating apparatus according to  claim 1 , wherein when the refrigerant is R600A, the system pressure of the refrigerating apparatus is set to 8 Bar. 
     
     
         8 . The refrigerating apparatus according to  claim 1 , wherein when the refrigerant is R417A, the system pressure of the refrigerating apparatus is set to 40 Bar. 
     
     
         9 . The refrigerating apparatus according to  claim 1 , wherein when the refrigerant is R4100, the system pressure of the refrigerating apparatus is set to 40 Bar. 
     
     
         10 . The refrigerating apparatus according to  claim 1 , wherein when the refrigerant is R407C, the system pressure of the refrigerating apparatus is set to 30 Bar.
