Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a high-efficiency refrigeration system. Background Art

[0002] The refrigeration system uses a compressor to compress the refrigerant and guide the refrigerant through corresponding pipes (such as copper pipes) into the condenser and evaporator for heat exchange.

[0003] Traditional refrigeration systems mainly use the heat exchange principle of condensers or evaporators for heating or cooling. This process can only achieve cooling or heating alone, and will cause some energy waste when cooling or heating alone. For example, the heat pump system for hot water production uses the principle that the high-temperature and high-pressure gaseous refrigerant with large heat in the condenser in the refrigerant circulation system needs to dissipate heat and liquefy. The condenser is placed in a heat exchange terminal (such as a water storage container) and uses water at room temperature to absorb heat to obtain hot water, and then the hot water is transported to the required place through a pipeline, such as domestic hot water for bathing, washing dishes, etc. On the contrary, when there is a demand for cold water, the evaporator is placed in a heat exchange terminal (such as a water storage container) and the heat in the normal temperature or high temperature water is used to gasify the low-temperature and low-pressure liquid refrigerant. In this process, the refrigerant absorbs the heat in the water to obtain cold water, and then the cold water is transported to the required place through a pipeline, such as equipment cooling water.

[0004] However, in the technology of related refrigeration systems, the condenser and evaporator are generally fin structures or micro-channel aluminum row structures, and the condenser and evaporator require a large accommodation space, which causes the overall volume of the refrigeration system to be larger, and increases the installation space required for the refrigeration system, thereby increasing the accessories cost and installation cost of the refrigeration system.

[0005] Moreover, the length of the conduits (such as copper tubes) in the relevant refrigeration systems is too long, which causes great resistance to the flow of the refrigerant, resulting in low working efficiency of the refrigeration system. At the same time, longer pipelines are easily damaged by external forces, and there is also a risk of leakage at various joints. Especially when the operating pressure of the refrigeration system is high, the risk of leakage of the refrigerant (such as R410a, CO2, etc.) in the operating pipeline is greater, and there is even a risk of explosion. Utility Model Content

In addition, since the length of the conduit is shortened, the refrigerant filling amount in the refrigeration system can be reduced and the running path of the refrigerant can be shortened. The reduction in the refrigerant filling amount and the shortening of the running path can improve the working efficiency of the refrigeration system and reduce the risk of damage and leakage of the refrigeration pipeline.

[0033] In order to facilitate the understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the relevant drawings.

[0034] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to another element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention pertains. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] Combine the following Figures 1 to 4 It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0037] See also Figures 1 to 4 An embodiment of the utility model provides a high-efficiency refrigeration system, which includes a compressor 100, a first high-efficiency heat exchanger 200, a second high-efficiency heat exchanger 300 and an expansion valve 400.

[0038] The compressor 100, the first high-efficiency heat exchanger 200, the expansion valve 400 and the second high-efficiency heat exchanger 300 are connected in series in sequence, and the second high-efficiency heat exchanger 300 is connected to the compressor 100 to form a heat exchange circulation loop.

[0039] The first high-efficiency heat exchanger 200 is disposed on the compressor 100 and forms an integrated structure with the compressor 100 ; the second high-efficiency heat exchanger 300 is also disposed on the compressor 100 and forms an integrated structure with the compressor 100 .

[0040] Specifically, the high-efficiency refrigeration system further includes a plurality of conduits 500 , and the conduits 500 include a first conduit 510 , a second conduit 520 , a third conduit 530 and a fourth conduit 540 .

[0041] Combination Figure 4The first high-efficiency heat exchanger 200 is connected to the compressor 100 using a first conduit 510, the expansion valve 400 is connected to the first high-efficiency heat exchanger 200 using a second conduit 520, the second high-efficiency heat exchanger 300 is connected to the expansion valve 400 using a third conduit 530, and the compressor 100 is connected to the second high-efficiency heat exchanger 300 using a fourth conduit 540 to form a heat exchange circulation loop.

[0042] Combination Figure 2 When the first high-efficiency heat exchanger 200 is a condenser, the second high-efficiency heat exchanger 300 is an evaporator. The refrigerant of the refrigeration system flows out of the compressor 100, passes through the condenser, the expansion valve, and the evaporator in sequence, and finally flows back to the compressor 100. The condenser includes a first inlet 210 and a first outlet 220. The first inlet 210 and the first outlet 220 can be externally connected to a first heat exchange terminal (for example, an air conditioner outdoor unit). When the external heat exchange medium (for example, water) flows through the condenser, the air conditioner outdoor unit can achieve heat dissipation. The evaporator includes a second inlet 310 and a second outlet 320. The second inlet 310 and the second outlet 320 can be externally connected to a second heat exchange terminal (for example, an air conditioner indoor unit). When the external heat exchange medium (for example, water) flows through the evaporator, the air conditioner indoor unit can achieve refrigeration.

[0043] It can be understood that the high-efficiency refrigeration system provided by the embodiment of the utility model, by arranging the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 on the compressor 100, the two high-efficiency heat exchangers respectively form an integrated structure with the compressor 100, so that the overall volume of the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 after being connected to the compressor 100 is reduced, thereby reducing the overall volume of the refrigeration system and reducing the accessories cost and installation cost of the refrigeration system; at the same time, since the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 respectively form an integrated structure with the compressor 100, the length of the conduit 500 connecting the two high-efficiency heat exchangers and the compressor 100 can be greatly shortened, and the installation space required for the conduit 500 can also be reduced, which can further reduce the overall volume of the refrigeration system and reduce the installation cost. In addition, since the length of the conduit 500 is shortened, the refrigerant filling amount in the refrigeration system can be reduced and the running path of the refrigerant can be shortened. The reduction in the refrigerant filling amount and the shortening of the running path can improve the working efficiency of the refrigeration system and reduce the risk of damage and leakage of the refrigeration pipeline.

[0044] Combination Figure 1 and Figure 2 In some embodiments of the present invention, the compressor 100 includes a fixing bracket 110 , which is disposed on the top of the compressor 100 , and the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 are fixed on the fixing bracket 110 .

[0045] Specifically, the fixing bracket 110 includes a first fixing plate 111 and a second fixing plate 112. The first fixing plate 111 is fixed to the top of the compressor 100. A clamping space is formed between the first fixing plate 111 and the second fixing plate 112. The first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 are fixed in the clamping space. The first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 are arranged on the top of the compressor 100, which can make the structure of the refrigeration system simpler and save manufacturing costs while reducing the volume.

[0046] See also Figure 3 In some embodiments of the present invention, the expansion valve 400, the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 are located on the same plane. This can reduce the space occupied by the expansion valve 400, the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 along the axial direction of the compressor 100, and further reduce the overall volume of the high-efficiency refrigeration system.

[0047] Of course, in other embodiments of the present invention, the expansion valve 400, the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 can also be arranged on the side wall of the compressor 100, so that the radial space of the compressor 100 can be fully utilized, while also shortening the axial space of the compressor 100.

[0048] Specifically, the first high-efficiency heat exchanger 200 is connected to the compressor 100 using the first conduit 510, the second high-efficiency heat exchanger 300 is connected to the compressor 100 using the fourth conduit 540, the expansion valve 400 is connected to the first high-efficiency heat exchanger 200 using the second conduit 520, and the expansion valve 400 is connected to the second high-efficiency heat exchanger 300 using the third conduit 530. Among them, the first conduit 510, the second conduit 520, the third conduit 530 and the fourth conduit 540 are all hard conduits, such as hard copper pipes. The use of hard conduits can stably fix the expansion valve 400, the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 on the side wall of the compressor 100 without the need for additional brackets, which can save costs.

[0049] Furthermore, in order to minimize the space between the expansion valve 400, the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 in the radial direction of the compressor 100, the expansion valve 400, the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 are arranged in a circle with the axis of the compressor 100 as the center.

[0050] In addition, the expansion valve 400 is also disposed between the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300 to fully utilize the space between the first high-efficiency heat exchanger 200 and the second high-efficiency heat exchanger 300, thereby reducing the overall volume of the high-efficiency refrigeration system and reducing installation costs.
