[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a power-saving device and an air conditioner to increase the cooling capacity of the air conditioner.

[0009] In some embodiments, the energy-saving device includes: a housing with a liquid inlet; and a flow-guiding structure including an inlet and an outlet, the flow-guiding structure being located inside the housing, the inlet communicating with the liquid inlet, and the outlet opposite to the inner wall of the housing. The flow-guiding structure is used to reduce the concentration of the gas-liquid mixed refrigerant as it flows out from the outlet. When the gas-liquid mixed refrigerant flows out from the outlet of the flow-guiding structure, the flow-guiding structure can reduce the concentration of the gas-liquid mixed refrigerant, thereby causing the gas-liquid mixed refrigerant to flow upwards in a dispersed manner, thus better separating the gas and liquid. The better the separation effect of the gas-liquid refrigerant, that is, the more thoroughly the liquid and vapor are separated, the faster the air conditioner cools and the better the cooling effect. This improves the cooling effect of the air conditioner.

[0010] In some embodiments, the flow guiding structure includes: a first cylinder, the bottom of which is connected to the liquid inlet; and a second cylinder, the bottom of which is connected to the top of the first cylinder, the outlet of which faces the top wall of the housing, and the diameter of the second cylinder gradually increases from its bottom to its top. In this way, the gas-liquid mixed refrigerant flowing out from the top of the second cylinder (the outlet of the flow guiding structure) has its velocity appropriately reduced, thus reducing the concentration of the gas-liquid mixed refrigerant and causing it to flow upwards in a dispersed manner, resulting in better gas-liquid separation. On the other hand, the gas-liquid mixed refrigerant retains a certain velocity, allowing it to impact the top wall of the housing at high speed, separating the gas and liquid phases, thereby completing one gas-liquid separation.

[0011] In some embodiments, the height of the flow guiding structure is greater than or equal to half the internal height of the housing. This is because after the gas-liquid mixed refrigerant rushes out from the outlet of the flow guiding structure 120, the liquid refrigerant will fall back due to gravity. By adopting such a height for the flow guiding structure, all the liquid refrigerant can fall back, resulting in more complete gas-liquid separation.

[0012] In some embodiments, the flow guiding structure includes: a baffle that encloses the liquid inlet within its internal space; and a cover plate that covers the top of the baffle, wherein the cover plate is provided with multiple through holes. In this way, gaseous refrigerant can easily flow out from the through holes (outlets of the flow guiding structure) on the cover plate. The through holes can reduce the concentration of the gas-liquid mixed refrigerant, and the multiple holes disperse the gas-liquid mixed refrigerant, causing it to flow upwards in a dispersed manner. This not only improves the gas-liquid separation effect but also prevents the gas-liquid mixed refrigerant from being too concentrated and impacted too violently, which could cause small droplets to be sucked away by the supplementary gas at the top, resulting in liquid carryover during supplementary gas filling.

[0013] In some embodiments, the housing is further provided with a liquid outlet; the power-saving device further includes a baffle, disposed inside the housing and erected at the liquid outlet. Thus, the baffle can prevent eddies from forming inside the housing.

[0014] In some embodiments, the power-saving device further includes: a baffle structure, longitudinally disposed within the housing, dividing the internal space of the housing into a first region and a second region; wherein the housing is further provided with an air outlet and a liquid outlet, the air outlet and the liquid outlet being connected to the first region, the liquid inlet being connected to the second region, and the flow guiding structure being located in the second region; the gas-liquid mixed refrigerant ejected from the flow guiding structure completes a first gas-liquid separation, and then the gas-liquid mixed refrigerant undergoes a second gas-liquid separation through the baffle structure. Thus, when the gas-liquid mixed refrigerant is ejected from the second cylinder and impacts the top wall of the housing at high speed, or is ejected from the through-hole of the cover plate, a first gas-liquid separation is completed. Afterwards, the gas-liquid mixed refrigerant continues to pass through the baffle structure, and through reciprocating flow, the liquid refrigerant sinks to the bottom of the housing, while the gaseous refrigerant rises to the top of the housing. In this way, the baffle structure performs a second gas-liquid separation of the gas-liquid mixed refrigerant.

[0015] In some embodiments, the baffle structure includes: a plurality of longitudinally arranged baffles, with a predetermined distance between adjacent baffles to form a channel for the flow of a gas-liquid mixed refrigerant; gaps are provided between the top and bottom of the plurality of baffles and the top and bottom walls of the housing, so that the gas-liquid mixed refrigerant flows longitudinally along the channel and deflects back. Thus, by causing the gas-liquid mixed refrigerant to flow up and down repeatedly, the liquid refrigerant sinks to the bottom of the housing, while the gaseous refrigerant rises to the top of the housing.

[0016] In some embodiments, the power-saving device further includes a gas-liquid separator disposed within the housing and corresponding to the gas outlet of the housing, for further gas-liquid separation of the gas-liquid mixed refrigerant. The gas-liquid mixed refrigerant flowing out from the baffle structure enters the gas-liquid separator for a third gas-liquid separation. After the third gas-liquid separation, the refrigerant flows out of the power-saving device from the gas outlet of the housing, at which point the refrigerant is mostly in gaseous state.

[0017] In some embodiments, the gas-liquid separator is at a preset angle to the horizontal plane. This allows the filter screen of the gas-liquid separator to achieve the best filtration performance, making it easier for the filtered droplets to converge and reach a critical point, where they then drip down under the influence of gravity.

[0018] In some embodiments, the air conditioner includes the aforementioned power-saving device.

[0019] The energy-saving device and air conditioner provided in this disclosure can achieve the following technical effects:

[0020] The flow-guiding structure is located inside the casing and corresponds to the liquid inlet. When the external gas-liquid mixed refrigerant enters the economizer, it first enters the flow-guiding structure and is guided by it to flow out from the outlet. As the gas-liquid mixed refrigerant flows out from the outlet, the flow-guiding structure reduces the concentration of the gas-liquid mixed refrigerant, causing it to flow upwards in a dispersed manner, thus better separating the gas and liquid components. The better the separation effect of the gas-liquid refrigerant, that is, the more thoroughly the liquid and vapor are separated, the faster the air conditioner cools and the better the cooling effect. This improves the cooling efficiency of the air conditioner.

[0021] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0044] Combination Figure 1 As shown, this embodiment of the present disclosure provides a power-saving device 100, including: a housing 110 and a flow guiding structure 120. A liquid inlet 111 is provided at a first position at the bottom of the housing 110, and the liquid inlet 111 is connected to a liquid inlet pipe 116. A liquid outlet 112 is provided at a second position at the bottom of the housing 110, and the liquid outlet 112 is connected to a liquid outlet pipe 117. An air outlet 113 is provided at the top of the housing 110, and the air outlet 113 is connected to a suction pipe 118. The air outlet 113 and the liquid inlet 111 are spatially far apart; for example, the air outlet 113 is located at the upper left of the housing 110, and the liquid inlet 111 is located at the lower right of the housing 110, so that the gas-liquid mixed refrigerant can undergo sufficient gas-liquid separation during its movement from the liquid inlet 111 to the air outlet 113.

[0045] A flow guiding structure 120 is disposed inside the housing 110. The flow guiding structure 120 has an inlet and an outlet. The inlet of the flow guiding structure 120 is connected to the liquid inlet 111, and the outlet is opposite to the inner wall of the housing 110. The gas-liquid mixed refrigerant enters the energy-saving device 100 through the liquid inlet 111, and flows out through the outlet of the flow guiding structure 120 after being guided by it. When the gas-liquid mixed refrigerant flows out from the outlet of the flow guiding structure 120, the flow guiding structure 120 reduces the concentration of the gas-liquid mixed refrigerant, thereby causing the gas-liquid mixed refrigerant to disperse and rise to the inner wall of the housing 110, thus better separating the gas and liquid components.

[0046] The energy-saving device 100 provided in this embodiment has a flow-guiding structure 120 located inside the housing 110 and corresponding to the liquid inlet 111 of the housing 110. When external gas-liquid mixed refrigerant enters the energy-saving device 100, it first enters the flow-guiding structure 120 and flows out from the outlet of the flow-guiding structure 120 under the guidance of the flow-guiding structure 120. When the gas-liquid mixed refrigerant flows out from the outlet of the flow-guiding structure 120, the flow-guiding structure 120 can reduce the concentration of the gas-liquid mixed refrigerant, thereby causing the gas-liquid mixed refrigerant to flow upward in a dispersed manner, thus better separating the gas and liquid. The better the separation effect of the gas-liquid refrigerant, that is, the more thoroughly the liquid and vapor are separated, the faster the air conditioner cools and the better the cooling effect. In this way, the cooling effect of the air conditioner can be improved.

[0047] Optionally, the outlet of the flow guiding structure 120 adopts an open-ended variable-diameter form, that is, the cross-section of the outlet gradually increases along the direction of refrigerant movement (from bottom to top). The open-ended variable-diameter outlet can appropriately reduce the flow velocity of the gas-liquid mixed refrigerant, thereby reducing the concentration of the gas-liquid mixed refrigerant and causing the gas-liquid mixed refrigerant to flow upward in a dispersed manner, thus improving the gas-liquid separation effect of the gas-liquid mixed refrigerant.

[0048] Optionally, the outlet of the flow guiding structure 120 can be porous. A porous outlet can also reduce the concentration of the gas-liquid mixed refrigerant. The pores disperse the gas-liquid mixed refrigerant, causing it to flow upwards in a dispersed manner. This can not only improve the gas-liquid separation effect, but also prevent the gas-liquid mixed refrigerant from being too concentrated and impacted too violently, which could cause small droplets to be sucked away by the supplementary gas at the top, resulting in liquid carrying away with the supplementary gas.

[0049] Optionally, combined Figure 1As shown, the flow guiding structure 120 includes a first cylinder 121 and a second cylinder 122. The first cylinder 121 is a cylindrical body with a constant inner diameter. The bottom of the first cylinder 121 is connected to the liquid inlet 111. The second cylinder 122 is a conical body with an inner diameter that gradually increases from its bottom to its top, i.e., the second cylinder 122 is an inverted conical body. The inner diameter of the bottom of the second cylinder 122 is equal to the inner diameter of the first cylinder 121, and the bottom of the second cylinder 122 is connected to the top of the first cylinder 121 so that the second cylinder 122 and the first cylinder 121 are connected as one unit. The top of the second cylinder 122 faces the top wall of the shell 110. In this way, the velocity of the gas-liquid mixed refrigerant flowing out from the top of the second cylinder 122 (the outlet of the flow guiding structure 120) is appropriately reduced, thereby reducing the concentration of the gas-liquid mixed refrigerant and causing the gas-liquid mixed refrigerant to flow upward in a dispersed manner, resulting in better gas-liquid separation. On the other hand, the gas-liquid mixed refrigerant retains a certain velocity so that it can impact the top wall of the housing 110 at high speed, causing the gas and liquid phases to separate and completing one gas-liquid separation.

[0050] Optionally, after the gas-liquid mixed refrigerant rushes out from the outlet of the guide structure 120, the liquid refrigerant will fall back due to gravity. Based on this, the height H of the guide structure 120 within the shell 110 (the total height of the first cylinder 121 and the second cylinder 122) is greater than or equal to half the internal height of the shell 110. This ensures that all the liquid refrigerant falls back, resulting in more thorough gas-liquid separation.

[0051] Optionally, the first cylinder 121 and the second cylinder 122 are integrally formed to reduce the management of parts.

[0052] Optionally, the first cylinder 121 and the second cylinder 122 are detachably connected, for example by using flanges, clips, nuts and bolts, to facilitate the installation, inspection, maintenance and replacement of the first cylinder 121 and the second cylinder 122.

[0053] Optionally, combined Figure 2As shown, the flow guiding structure 120 includes a baffle 123 and a cover plate 124. The baffle 123 is a single-bend plate, thus having two sides. The baffle 123, together with the bottom wall and side walls of the housing 110, forms an internal space, thereby enclosing the liquid inlet 111 of the housing 110 within this internal space. Alternatively, the baffle 123 is a bend plate with three or more bends, which, after bending, forms a closed structure with its ends connected. Its bottom is connected to the bottom wall of the housing 110, enclosing the liquid inlet 111 of the housing 110 within the internal space of the baffle 123. Alternatively, the baffle 123 is a cylinder, whose bottom is connected to the bottom wall of the housing 110, enclosing the liquid inlet 111 of the housing 110 within the internal space of the baffle 123. In addition, the baffle 123 can also be a baffle of the shape of an arc plate, etc., which is not specifically limited in this embodiment.

[0054] Optionally, the bottom of the enclosure 123 is fixedly connected to the bottom wall of the housing 110 by welding.

[0055] Optionally, the bottom of the enclosure 123 is detachably connected to the bottom wall of the housing 110, for example, by means of flanges, clips, nuts and bolts, to facilitate the installation, inspection, maintenance and replacement of the enclosure 123.

[0056] A cover plate 124 is installed on top of the enclosure 123. Optionally, the cover plate 124 and the enclosure 123 are integrally formed or connected together by welding. Optionally, the cover plate 124 and the enclosure 123 are detachably connected together by flanges, clips, nuts, bolts, etc. Figures 3 to 5 As shown, the cover plate 124 is provided with multiple through holes 125. In this way, the gaseous refrigerant can easily flow out from the through holes 125 (the outlet of the flow guiding structure 120) on the cover plate 124. The through holes 125 can reduce the concentration of the gas-liquid mixed refrigerant. The multiple holes disperse the gas-liquid mixed refrigerant, so that the gas-liquid mixed refrigerant flows upward in a dispersed manner. This can not only improve the gas-liquid separation effect, but also prevent the gas-liquid mixed refrigerant from being too concentrated and impacted too violently, which would cause small droplets to be sucked away by the gas at the top, resulting in the problem of liquid being carried away by the gas.

[0057] Optionally, the through holes 125 are arranged in an array and regularly distributed on the cover plate 124 to improve the degree of dispersion of the gas-liquid mixed refrigerant, thereby improving the gas-liquid separation effect of the gas-liquid mixed refrigerant.

[0058] Optionally, the diameter of the through hole 125 is 5 mm.

[0059] Optionally, the number of through holes 125 can be calculated based on the required cooling capacity, and the flow rate of the gas-liquid mixed refrigerant passing through the through holes 125 can be controlled within 1.6 m / s.

[0060] Optionally, combined Figure 6 As shown, the flow guiding structure 120 includes a third cylinder 126 and a fourth cylinder 127. The third cylinder 126 is a cylindrical body with a constant inner diameter. The bottom of the third cylinder 126 is connected to the liquid inlet 111. The fourth cylinder 127 is a curved cylinder with a constant inner diameter. The inner diameter of the fourth cylinder 127 is equal to the inner diameter of the third cylinder 126, and the bottom of the fourth cylinder 127 is connected to the top of the third cylinder 126, so that the fourth cylinder 127 and the third cylinder 126 are connected as one unit. The outlet of the fourth cylinder 127 faces the side wall of the housing 110. In this way, the gas-liquid mixed refrigerant flowing out from the outlet of the fourth cylinder 127 (the outlet of the flow guiding structure 120) impacts the side wall of the housing 110 at high speed, thereby completing one gas-liquid separation. Optionally, the inner diameter of the outlet of the fourth cylinder 127 is less than or equal to the inner diameter of the liquid inlet 111. This allows the gas-liquid mixed refrigerant to impact the side wall of the shell 110 at a higher velocity, thereby improving the gas-liquid separation effect. Optionally, the fourth cylinder 127 is a bend, which can reduce the flow velocity of the gas-liquid mixed refrigerant, thereby reducing the concentration of the gas-liquid mixed refrigerant and thus improving the gas-liquid separation effect.

[0061] Optionally, the third cylinder 126 and the fourth cylinder 127 are integrally formed or connected by welding to reduce the management of parts.

[0062] Optionally, the third cylinder 126 and the fourth cylinder 127 are detachably connected, for example by using flanges, clips, nuts and bolts, to facilitate the installation, inspection, maintenance and replacement of the third cylinder 126 and the fourth cylinder 127.

[0063] Optionally, combined Figure 7 As shown, the power saver 100 also includes a baffle 130. The baffle 130 is disposed inside the housing 110 and erected at the liquid outlet 112 of the housing 110, that is, directly above the liquid outlet pipe 117. In this way, the baffle 130 can prevent eddies from being generated inside the housing 110.

[0064] Optionally, the baffle 130 is centrally located relative to the liquid outlet 112 of the housing 110 and parallel to the axis of the housing 110 (the housing 110 is a horizontally placed cylinder, and the axis of the housing 110 is parallel to the horizontal plane).

[0065] Optionally, the length of the baffle 130 is 2.5 to 3 times the inner diameter of the outlet 112 of the housing 110.

[0066] Optionally, the height of the baffle 130 is set according to the required liquid level of the refrigerant, generally one-quarter of the internal height of the housing 110.

[0067] Optionally, combined Figure 1 , Figure 2 and Figure 6 As shown, the power saver 100 also includes a baffle structure 140. The baffle structure 140 is longitudinally disposed within the housing 110, dividing the internal space of the housing 110 into a first region 114. Figure 1 The left-hand area shown) and the second area 115 ( Figure 1 (as shown in the right-hand region), and connects the air outlet 113 and liquid outlet 112 of the housing 110 to the first region 114, and connects the liquid inlet 111 of the housing 110 to the second region 115. Correspondingly, in order to connect with the liquid inlet 111 of the housing 110, the flow guiding structure 120 is also located in the second region 115.

[0068] When the gas-liquid mixed refrigerant is ejected from the second cylinder 122 and impacts the top wall of the shell 110 at high speed, or when it is ejected from the through hole 125 of the cover plate 124, a gas-liquid separation is completed. Afterwards, the gas-liquid mixed refrigerant continues to pass through the baffle structure 140. Through reciprocating flow, the liquid refrigerant sinks to the bottom of the shell 110, while the gaseous refrigerant rises to the top of the shell 110. Thus, the baffle structure 140 performs a secondary gas-liquid separation of the gas-liquid mixed refrigerant.

[0069] Optionally, the baffle structure 140 includes: a plurality of longitudinally arranged baffles, with a preset distance between adjacent baffles to form a channel for the flow of the gas-liquid mixed refrigerant. Figure 2 As shown, multiple baffles are fixed together by screws 146. Specifically, the screws 146 are transversely inserted through each baffle, and nuts 147 are connected to both ends of the screws 146. At the same time, gaps are left between the top and bottom of the baffle structure 140 (the top and bottom of each baffle) and the top and bottom walls of the housing 110, respectively, so as to allow the gas-liquid mixed refrigerant to flow longitudinally along each baffle and turn back.

[0070] Optionally, see again Figure 1 , Figure 2 and Figure 6The flow-deflecting structure 140 includes a first baffle plate 141, a second baffle plate 142, and a third baffle plate 143. The channel between the first baffle plate 141 and the second baffle plate 142 is the first channel 144, and the channel between the second baffle plate 142 and the third baffle plate 143 is the second channel 145. When the gas-liquid mixed refrigerant is ejected from the outlet of the flow-guiding structure 120 and completes one gas-liquid separation, it rises to the top of the shell 110, flows into the first channel 144 from the top of the first baffle plate 141 and sinks along the first channel 144, then enters the second channel from the bottom of the second baffle plate 142 and rises along the second channel 145, and finally flows out of the flow-deflecting structure 140 from the top of the third baffle plate 143. As the gas-liquid mixed refrigerant continuously flows back and forth within the flow-deflecting structure 140, the gaseous refrigerant rises more easily, and the liquid refrigerant sinks more easily, thereby achieving secondary gas-liquid separation of the gas-liquid mixed refrigerant.

[0071] Optionally, combined Figure 1 , Figure 2 and Figure 6 As shown, the energy-saving device 100 also includes a gas-liquid separator 150. The gas-liquid separator 150 is disposed within the housing 110 and corresponds to the gas outlet 113 of the housing 110. The gas-liquid mixed refrigerant flowing out from the baffle structure 140 enters the gas-liquid separator 150 for three gas-liquid separations. After the three gas-liquid separations, the refrigerant flows out of the energy-saving device 100 from the gas outlet 113 of the housing 110; at this point, the refrigerant is predominantly gaseous.

[0072] Optionally, the gas-liquid separator 150 is composed of multiple strands of metal wire mesh.

[0073] Optionally, combined Figure 7 As shown, the gas-liquid separator 150 forms a preset angle A with the horizontal plane. This allows the filter screen of the gas-liquid separator 150 to achieve the best filtration performance, making it easier for the filtered droplets to converge and reach the critical point, where they drip down under the influence of gravity.

[0074] Optionally, the preset included angle A is set to 10° to 15°.

[0075] Combination Figure 8 As shown, this embodiment of the present disclosure provides a refrigerant circulation system 200, which includes the aforementioned power saver 100.

[0076] The refrigerant circulation system 200 also includes: a compressor 210, a condenser 220, a first-stage orifice plate 230, a second-stage orifice plate 240, and an evaporator 250.
