Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The refrigeration system of the embodiment includes a compressor, a condenser, a capillary tube 2, an evaporator and a liquid storage device 1, which are connected in sequence to form a refrigeration loop, wherein a refrigerant outlet of the liquid storage device 1 is connected with an air return port of the compressor through an air return pipe 3, and at least part of the capillary tube 2 is wound on the liquid storage device 1 and the air return pipe 3, as shown in fig. 1 and 2.
The refrigeration system of the present embodiment enables rational installation of the capillary tube 2 even if it is lengthened by partially winding the capillary tube 2 around the liquid reservoir 1. And, since the capillary tube 2 is wound around the liquid reservoir 1, it is possible to raise the return air temperature without increasing the length of the return air tube 3, avoiding the generation of condensation on the return air tube 3.
Specifically, capillary 2 of partial winding on reservoir 1 can carry out the heat transfer with reservoir 1 to reservoir 1 can retrieve the heat of capillary 2, guarantees to follow the gaseous temperature rise of reservoir 1 flow to the compressor, obtains the return-air temperature that satisfies the demands. Therefore, the refrigeration system of the present embodiment can obtain a return air temperature meeting the requirement without increasing the length of the return air pipe 3.
In order to keep the liquid storage device 1 always storing refrigerant and prevent the compressor from "starving" due to refrigerant backflow under certain conditions (for example, when the refrigeration system is switched from the freezing mode to the refrigerating mode), the embodiment preferably has the refrigerant outlet of the evaporator higher than the refrigerant inlet of the liquid storage device 1.
Further, a condensing agent outlet of the evaporator is connected with a condensing agent inlet of the liquid storage device 1 through a liquid storage device 1 air inlet pipe, and preferably, a buffering pipe section of the condensing agent is formed on the liquid storage device 1 air inlet pipe. Therefore, after the condensing agent passes through the buffer pipe section of the air inlet pipe of the liquid storage device 1 at a high speed, the flow speed of the condensing agent is reduced, so that the condensing agent is prevented from entering the liquid storage device 1 at a high speed, liquid is prevented from entering the compressor, and the gas-liquid separation effect of the liquid storage device 1 is effectively guaranteed.
Wherein the specific form of the buffer tube section is not limited. The buffer pipe section in fig. 2 is, for example, a bent pipe section 4 at the location of the condensate inlet of the reservoir 1. Of course, the curved tube section 4 in fig. 2 does not constitute a limitation of the cushioned tube section of the present application. For example, the buffer pipe section may also be a variable diameter pipe section with a suddenly increased cross-sectional size, or the buffer pipe section may also be a wave pipe section, etc.
It is worth mentioning that the curved pipe section 4 in fig. 2 can also be used for storing part of the refrigerant, so that the liquid storage capacity of the liquid storage device 1 is increased in a phase-change manner, and the problem of refrigerant storage under variable working conditions is solved.
In fig. 1 and 2, a middle section of a capillary tube 2 is wound around an outer wall of the liquid reservoir 1, and both ends of the capillary tube 2 are wound around a refrigerant inlet position of the evaporator and the air return pipe 3, respectively (not shown in the drawings). In this case, the fixed mounting requirement of the capillary 2 can be ensured. Further, the winding form of the capillary 2 can be adjusted according to the change of the length requirement of the capillary 2.
In fig. 1 and 2, the middle section of the capillary tube 2 is wound on the outer wall of the liquid reservoir 1 in a spiral manner. And, with the change of the length of the capillary 2, can realize the fixed mounting of the capillary 2 through adjusting the pitch. Of course, the manner in which the capillary tube 2 is wound on the outer wall of the reservoir 1 is not limited to a spiral manner, but it may be wound by any other feasible manner.
In this embodiment, when the refrigeration system is a parallel dual cycle system, that is, the evaporator includes a refrigeration evaporator and a freezing evaporator connected in parallel, in this case, it is preferable that a refrigerant inlet of the refrigeration evaporator is lower than a refrigerant inlet of the freezing evaporator.
In fig. 2, a parallel line connecting a refrigerating evaporator and a freezing evaporator, which are not shown in the figure, is shown.
Because the refrigeration system is under the refrigeration operating mode, the pressure of the refrigeration evaporator is higher than the pressure of the freezing evaporator under the freezing operating mode. Therefore, the refrigerant inlet of the refrigeration evaporator is lower than the refrigerant inlet of the freezing evaporator, and the refrigerant can be prevented from flowing into the freezing evaporator from the refrigeration evaporator when the refrigeration system is switched from freezing to refrigeration. Furthermore, the condensing agent inlet of the refrigeration evaporator is lower than that of the freezing evaporator, so that the problem of refrigeration delay caused by the fact that the condensing agent flows back to the freezing evaporator can be avoided.
And, when the refrigerant inlet of the refrigerating evaporator and the refrigerant inlet of the freezing evaporator are connected to the refrigerating circuit through a three-way pipe, the end of the capillary tube 2 may be wound at the three-way pipe. In this case, the capillary tube 2 can be supported at the position where the three-way pipe passes, so that the strength of the structure of the capillary tube 2 is ensured; furthermore, the capillary tube 2 may also be branched at a tee to be connected to the refrigeration evaporator and the freezing evaporator, respectively.
In this case, the capillary tube 2 includes a first capillary tube 2 and a second capillary tube 2, the first capillary tube 2 being connected in series with the refrigerating evaporator, and the second capillary tube 2 being connected in series with the freezing evaporator.
Wherein the first capillary 2 and the second capillary 2 are each wound on the reservoir 1 in a helical manner. Also, the first capillary tube 2 and the second capillary tube 2 may be mounted in parallel on the reservoir 1 in the same winding manner.
It should be noted that the refrigeration system of the present embodiment may be not only a parallel dual system, but also any other form disclosed in the prior art. For example, the refrigeration system of the present embodiment may be a single cycle system, a triple cycle system, or the like.
On the basis, the embodiment also provides a refrigerator, which comprises the refrigeration system.
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.
