Similarly, the refrigerant in the refrigeration system is not limited to carbon dioxide, and as long as the refrigerant pressure of any refrigeration system is higher under the operating condition, the liquid storage assembly of the refrigeration system of the embodiment of the invention can be adopted for refrigerant injection.
Referring to fig. 1, a liquid storage assembly of a refrigeration system according to an embodiment of the invention includes:
a liquid storage container 1;
filling the container 2;
the first pipeline is communicated with the liquid storage container 1 and the filling container 2;
a second pipe 33 having a first end formed with a filling port 5 and a second end communicating with the filling container 2;
a third pipe 34 having a first end formed with a discharge port 6 and a second end communicating with the filling container 2;
of the first, second and third pipes 33, 34, at least the first pipe is provided with a valve.
This refrigerating system's stock solution subassembly still is provided with filling container 2 except stock solution container 1, and fills filling container 2 through first pipeline intercommunication stock solution container 1, and then through the switching of controlling the valve on the first pipeline, can control stock solution container 1 and fill the intercommunication or the disconnection between the container 2. When need pour into the refrigerant into to refrigerating system, even if refrigerating system is in the running state, also can be through breaking off first pipeline for fill equipment not directly pour into the refrigerant into in the middle of refrigerating system's the refrigeration circuit, but in the middle of filling the container 2 with the refrigerant injection earlier, avoid the refrigerant to pour into the problem that the refrigerant can't continue to pour into because of refrigeration circuit pressure is too high in the middle of the process into. After the refrigerant is injected, the first pipe may be turned on, so that the refrigerant in the filling container 2 enters the refrigeration circuit through the liquid storage container 1.
The structure and material of the filling container 2 have no special requirements, and the storage requirement of the refrigerant can be met. For example, the filling container 2 may be made of the same material as the liquid storage container 1, and the filling container 2 may have the same shape as the liquid storage container 1 but may have a smaller size than the liquid storage container 1. In addition, the liquid storage container 1, i.e. the liquid storage device in the refrigeration system, is generally disposed at the inlet of the compressor, but may be disposed at any other feasible position according to the rules of the refrigeration system in the prior art. For another example, the filling container 2 may be different in shape, material, and size from the liquid storage container 1.
Because the liquid refrigerant and the gaseous refrigerant exist simultaneously during the refrigerant injection process, in order to facilitate the refrigerant to enter the liquid storage container 1 from the filling container 2, the first pipeline includes the first liquid pipe 31 and the first air pipe 32, valves are disposed on the first liquid pipe 31 and the first air pipe 32, and the valves are a pipe valve 42 disposed on the first air pipe 32 and a pipe valve 41 disposed on the first liquid pipe 31. Wherein, the air pipe valve 42 and the liquid pipe valve 41 can be both switch valves. When the refrigerant is injected into the liquid storage container 1 from the filling container 2, the switch valves (the liquid pipe valve 41 and the gas pipe valve 42) on the first liquid pipe 31 and the first gas pipe 32 can be opened simultaneously, so that the air pressure in the filling container 2 is equal to the air pressure in the liquid storage container 1, and the refrigerant in the filling container 2 can enter the liquid storage container 1. Of course, the valves on the first liquid pipe 31 and the first gas pipe 32 may be adjustable valves.
According to the embodiment of the invention, the lowest liquid level of the filling container 2 is not lower than the highest liquid level of the liquid storage container 1, so that the refrigerant can enter the liquid storage container 1 from the filling container 2 under the action of gravity, a driving unit (such as a driving pump) is not required to be additionally arranged, the manufacturing cost of a liquid storage assembly is saved, and the structure of a refrigerating system is simplified. When stock solution container 1 had the conventional operation liquid level, also can make to fill the minimum liquid level of filling container 2 and be not less than stock solution container 1's conventional operation liquid level, and then guarantee that after the refrigerant fills the notes, the liquid level in the middle of stock solution container 1 can reach its self conventional operation liquid level.
According to an embodiment of the present invention, a first end of the first liquid pipe 31 is connected to the bottom of the filling container 2, and a second end of the first liquid pipe 31 is connected to the top of the liquid storage container 1. At this time, the refrigerant in the filling container 2 may enter the liquid storage container 1 through the first liquid pipe 31 by gravity. And, with reference to fig. 1, the length of the first liquid pipe 31 is the shortest, so that the pipeline arrangement is convenient, and the cost is saved. Certainly, the second end of the first liquid pipe 31 may also be connected to the bottom of the liquid storage container 1, so that the refrigerant enters the liquid storage container 1 from the bottom of the liquid storage container 1, and the noise problem when the second end of the first liquid pipe 31 is connected to the top of the liquid storage container 1 is avoided.
According to the embodiment of the invention, the first end of the first air pipe 32 is connected with the top of the filling container 2, and the second end of the first air pipe 32 is connected with the top of the liquid storage container 1, so that the circulation of the gaseous refrigerant between the top of the filling container 2 and the top of the liquid storage container 1 is facilitated, and the balance of the air pressure between the filling container 2 and the liquid storage container 1 is ensured.
According to the embodiment of the present invention, a valve is also disposed in the second pipe 33, and the valve is a filling valve 43, so that the filling valve 43 is opened, the filling device is communicated with the second pipe 33, the refrigerant is filled into the second pipe 33 through the filling device, and the refrigerant enters the filling container 2 along the second pipe 33.
According to an embodiment of the invention, the third conduit 34 is provided with a valve, which is a blow-off valve 44. The function of the bleed valve 44 is mainly embodied in the following links: first, before the refrigerant is injected into the filling container 2, the third pipe 34 may be communicated with a vacuum-pumping device, the bleeding valve 44 is opened, so as to perform a vacuum-pumping operation on the filling container 2, and when a vacuum environment is formed inside the filling container 2, the bleeding valve 44 is closed, and the refrigerant is injected into the filling container 2 through the filling device. Secondly, as the refrigerant enters the filling container 2, the pressure in the filling container 2 is also changed, and the opening degree of the bleeding valve 44 can be adjusted to achieve the purpose of adjusting the pressure in the filling container 2. When the refrigerant in the filling container 2 is completely filled, the bleed valve 44 may be closed.
Wherein the fill valve 43 and the bleed valve 44 may be provided simultaneously. The fill valve 43 and the bleed valve 44 cooperate as follows: first, the fill valve 43 is closed and the purge valve 44 is opened, and the fill container 2 is vacuumized through the third pipe 34; then, the relief valve 44 is closed, the filling valve 43 is opened, and the refrigerant is filled into the filling container 2 through the second pipeline 33; then, as the pressure in the charging container 2 changes, the opening degree of the purge valve 44 is adjusted; finally, after the refrigerant charging is completed, the charging valve 43 and the discharging valve 44 are closed.
Further, after the "closing the filling valve 43 and the bleeding valve 44" is completed, the on-off valves on the first liquid pipe 31 and the first gas pipe 32 may be opened, so that the filled liquid refrigerant flows from the filling container 2 to the liquid storage container 1 through the first liquid pipe 31, and the filling is completed. As the air pressure between the fill container 2 and the reservoir 1 equilibrates, the air valve 42 on the first air line 32 may be closed.
The type of the on-off valve is not limited, and may be, for example, a stop valve, an electromagnetic valve, an electrically operated valve, or the on-off valve may be replaced by a regulating valve, but the on-off effect of the regulating valve is inferior to that of the on-off valve.
It is worth mentioning that the lengths of the second pipe 33 and the third pipe 34 are not limited, for example, the lengths of the second pipe 33 and the third pipe 34 may be very small, and then: the second conduit 33, i.e. the filling tube segment formed on the filling container 2, and having a length corresponding to the thickness of the filling container 2; the third conduit 34 is also a liquid storage tube section formed on the liquid storage container 1, and the length of the liquid storage tube section corresponds to the thickness of the liquid storage container 1. That is, when the lengths of the second and third pipes 33 and 34 are very small, no apparent pipe structure is seen at this time.
According to an embodiment of the present invention, the liquid storage assembly of the refrigeration system further comprises a first pressure sensor 71 for detecting the pressure of the refrigerant in the charging container 2. The opening of the bleed valve 44 is adjusted based on the pressure of the fill container 2 measured by the first pressure sensor 71 to ensure that the fill process is performed smoothly.
According to an embodiment of the present invention, the liquid storage assembly of the refrigeration system further includes a second pressure sensor 72 for detecting the pressure of the refrigerant in the liquid storage container 1. The pressure of the refrigerant in the refrigeration system can be detected in real time by the second pressure sensor 72, so as to control the charging process of the refrigerant.
Here, the specific type of the first pressure sensor 71 and the second pressure sensor 72 is not limited, and may be, for example, a semiconductor piezoelectric impedance diffusion pressure sensor, or may also be an electrostatic capacity type pressure sensor or the like.
According to an embodiment of the invention, a refrigeration system is further provided, and the refrigeration system comprises a refrigeration circuit formed by communicating an evaporator, a throttling device and a condenser, and a liquid storage assembly of the refrigeration system is arranged in the refrigeration circuit. Wherein, the stock solution subassembly generally sets up the low reaches at the condenser, and then guarantees that the liquid refrigerant after the condenser can be saved through the stock solution subassembly. The flow of the refrigerant in the refrigeration loop can be adjusted through the arrangement of the liquid storage assembly.
Wherein, because stock solution subassembly is including stock solution container 1 still including filling the fill container 2, and then this refrigerating system can also carry out the filling of refrigerant at any time, guarantees refrigerating system's refrigeration effect.
According to the refrigeration system of the embodiment of the invention, when the refrigeration system comprises the liquid pipe valve 41, the air pipe valve 42, the filling valve 43 and the relief valve 44 at the same time, the filling valve 43, the relief valve 44 and the air pipe valve 42 can be closed, only the liquid pipe valve 41 is opened, and the filling container 2 and the liquid storage container 1 are communicated into a whole through the first liquid pipe 31 when the refrigeration system is in normal operation.
The refrigeration system according to the embodiment of the present invention further includes a vacuum pumping assembly, which is communicated with the third pipe 34, so that a vacuum state in the filling container 2 can be ensured.
The above embodiments are merely illustrative of the present invention and are not to be construed as limiting the invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and the technical solution of the present invention is covered by the claims of the present invention.
