CLAIMS

1. A throttling and distributing component, comprising:

a main body extending from a first end to a second end, wherein a fluid enters the main body from the first end;

a regulator having a valve rod, wherein the valve rod passes through the second end and extends into the main body;

one or more openings disposed on a sidewall of the main body, each opening being in fluid communication with a plurality of branches extending from the main body respectively; and

a piston attached to the valve rod,

wherein the regulator is configured to adjust the position of the piston in the main body by using the valve rod, so as to selectively cover at least a part of each opening.

2. The throttling and distributing component according to claim 1, wherein the regulator is a stepper motor.

3. The throttling and distributing component according to claim 1 , wherein the opening is disposed near the second end.

4. The throttling and distributing component according to claim 3, wherein downstream parts of the plurality of branches extend in parallel relative to the main body, and upstream parts of the plurality of branches extend perpendicularly from the main body.

5. The throttling and distributing component according to claim 4, wherein the opening is a rectangular opening.

6. The throttling and distributing component according to claim 1, wherein the opening has an oval or circular shape.

7. The throttling and distributing component according to claim 1, wherein the opening has a hyperbolic or parabolic shape.

8. The throttling and distributing component according to claim 1, wherein the piston and the main body jointly define a cavity, the cavity being configured to receive a refrigerant that keeps in a liquid state in the cavity.

9. The throttling and distributing component according to claim 8, wherein in a process that the refrigerant enters the branch through the opening, at least a part of the refrigerant is gasified into a gaseous state, such that the refrigerant entering the branch keeps in two phases of gas and liquid.

10. A refrigerating system, comprising:

a condenser;

the throttling and distributing component according to any of claims 1 to 9 located downstream of the condenser, wherein an output end of the condenser is in fluid communication with the first end of the main body;

a plurality of evaporators or a plurality of evaporator passages located downstream of the throttling and distributing component and in fluid communication with the plurality of branches; and

a controller electrically connected to the regulator and configured to adjust the position of the piston by using the regulator.
