Abstract

A refrigerating apparatus applied to a refrigerator is disclosed. The refrigerating apparatus includes a refrigerant, a depressurization gas, an evaporator, a condenser, a first connecting pipe, a second connecting pipe, a third connecting pipe, a blower device and a refrigerator body. 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.

First claim

We claim:

1. A refrigerating apparatus applied to a refrigerator, comprising:
a refrigerant disposed in a pipeline of the refrigerating apparatus, the refrigerant comprising at least one of R290, R32, R404A or R410A;
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 refrigerator body provided with a refrigerating chamber and a freezing chamber, wherein the evaporator is located at a position in the refrigerator body corresponding to the refrigerating chamber and the freezing chamber, the condenser is located at a lower part of the refrigerator body, and the blower device is located below the refrigerating chamber and the freezing chamber.

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 4 , 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 R290, the system pressure of the refrigerating apparatus is set to 28 Bar.

8. The refrigerating apparatus according to claim 1 , wherein when the refrigerant is R32, the system pressure of the refrigerating apparatus is set to 50 Bar.

9. The refrigerating apparatus according to claim 1 , wherein when the refrigerant is R404A, the system pressure of the refrigerating apparatus is set to 36 Bar.

10. The refrigerating apparatus according to claim 1 , wherein when the refrigerant is R410A, the system pressure of the refrigerating apparatus is set to 40 Bar.
