Abstract

A refrigeration apparatus based on a molecular sieve, including a first molecular sieve device, a second molecular sieve device, a reversing valve, and a balancing valve, wherein an air flow alternately passes through the first molecular sieve device and the second molecular sieve device through the reversing valve, and then flows back through the balancing valve, so that the first molecular sieve device and the second molecular sieve device are regenerated. The first molecular sieve device and the second molecular sieve device are capable of separating a refrigerant from a depressurization gas, and the refrigerant is condensed after reaching a certain concentration to become a liquid refrigerant, and then enters an evaporator again for refrigeration.

First claim

We claim:

a reversing valve is provided with a first air inlet interface, a first air outlet interface, and a second air outlet interface;
a second storage tank is provided with a first air inlet interface, a second air inlet interface, and a first air outlet interface;
a first molecular sieve device is provided with a first interface and a second interface;
a second molecular sieve device is provided with a first interface and a second interface;
one end of the first blowing device is communicated with the outlet through a first connecting pipe, and the other end of the first blowing device is communicated with the first air inlet interface of the first storage tank through a second connecting pipe;

a second blowing device comprising a ventilator; the second blowing device is communicated with the first air outlet interface of the first storage tank through a third connecting pipe and is communicated with the first air inlet interface of the reversing valve through a fourth connecting pipe;
the liquid outlet is communicated with the inlet through a fifth connecting pipe; the first air outlet interface of the reversing valve is communicated with the first interface of the first molecular sieve device through a sixth connecting pipe, and the sixth connecting pipe is provided with the first valve for being communicated with the first storage tank; the second air outlet interface of the reversing valve is communicated with the first interface of the second molecular sieve device through a seventh connecting pipe, and the seventh connecting pipe is provided with the second valve for being communicated with the first storage tank; the second interface of the first molecular sieve device is communicated with the first air inlet interface of the second storage tank through an eighth connecting pipe, and the eighth connecting pipe is provided with a first one-way valve allowing an air flow to flow from the second interface of the first molecular sieve device to the first air inlet interface of the second storage tank; the second interface of the second molecular sieve device is communicated with the second air inlet interface of the second storage tank through a ninth connecting pipe, and the ninth connecting pipe is provided with a second one-way valve allowing the air flow to flow from the second interface of the second molecular sieve device to the second air inlet interface of the second storage tank; the first air outlet interface of the second storage tank is communicated with the inlet through a tenth connecting pipe; and one end of the balancing valve is communicated with the second interface of the first molecular sieve device through an eleventh connecting pipe, and the other end of the balancing valve is communicated with the first interface of the second molecular sieve device through a twelfth connecting pipe.

2. The refrigeration apparatus based on the molecular sieve according to claim 1 , wherein the first air inlet interface of the first storage tank is located at a top portion of the first storage tank.

3. The refrigeration apparatus based on the molecular sieve according to claim 2 , wherein the first air outlet interface of the first storage tank is located at an upper portion of the first storage tank and is located below the first air inlet interface of the first storage tank.

4. The refrigeration apparatus based on the molecular sieve according to claim 1 , wherein the liquid outlet is located at a bottom portion of the first storage tank.

5. The refrigeration apparatus based on the molecular sieve according to claim 1 , wherein the fifth connecting pipe comprises a liquid storage section, and the liquid storage section comprises a plurality of U-shaped pipes.

6. The refrigeration apparatus based on the molecular sieve according to claim 1 , wherein the first valve and/or the second valve are electronic valves.
