[0002] Air conditioners are widely used in various places as air conditioning devices. At present, air conditioners are generally equipped with compressors, condensers, evaporators and other components, and the purpose of air conditioning is achieved by using refrigerants. During the operation of the air conditioner, the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant. The gaseous refrigerant from the compressor flows through the condenser, cools down and reduces the pressure. The condenser discharges heat through the cooling water system. The refrigerant continues to flow through the throttling device and becomes a low-temperature and low-pressure liquid, flows through the evaporator, absorbs heat, and is compressed again.

[0003] During the operation of the air conditioner, the refrigerant in the compressor needs to be cooled by heat exchange to ensure the stable operation of the air conditioner. The condensation of the refrigerant in the traditional steam compressor depends on the ambient temperature, resulting in a lower cooling effect of the whole machine when the ambient temperature is high. In low-carbon energy-saving air conditioners, the cooling water cooled by the circulating water system is heat exchanged with the refrigerant in the compressor through a heat exchanger, which has a better cooling effect.

[0047] During the operation of the air conditioner, the refrigerant in the compressor needs to be cooled by heat exchange to ensure the stable operation of the air conditioner. The condensation of the refrigerant in the traditional steam compressor depends on the ambient temperature, resulting in a lower cooling effect of the whole machine when the ambient temperature is high. In low-carbon energy-saving air conditioners, the cooling water cooled by the circulating water system is heat exchanged with the refrigerant in the compressor through a heat exchanger, which has a better cooling effect.

[0048] In the related technologies, the circulating water systems of existing low-carbon energy-saving air conditioners have technical problems such as uneven water supply, the need for manual disassembly and cleaning of the water supply system, and easy blockage of the circulating pipelines, especially the water distribution pipelines.

[0049] An embodiment of the present application provides a low-carbon energy-saving air conditioning circulating liquid supply system, including a heat exchanger, a circulating liquid return pipe, a liquid separator, a heat dissipation device, a first container and a liquid pump. The heat exchanger is used to exchange heat with the refrigerant in the compressor, and one end of the circulating liquid return pipe is connected to the liquid outlet of the heat exchanger. The liquid separator includes a plurality of liquid separator tanks, the other end of the circulating liquid return pipe is connected to the liquid separator tank, and the liquid supply distances from the circulating liquid return pipe to at least two liquid separator tanks are the same. The heat dissipation device is connected to the liquid separator tank for cooling the liquid flowing out of the liquid separator tank. The first container is connected to the heat dissipation device for holding the liquid cooled by the heat dissipation device. One end of the liquid pump is connected to the first container, and the other end is connected to the liquid inlet of the heat exchanger, for pumping the liquid in the first container to the heat exchanger.

[0050] The low-carbon and energy-saving air-conditioning circulating liquid system provided in the embodiment of the present application has the same liquid supply distance between the circulating liquid return pipe and each liquid distribution tank, which can achieve equidistant and uniform liquid supply to improve the cooling effect of liquid such as water, thereby ensuring the energy efficiency of the low-carbon and energy-saving air-conditioning.

[0051] The present application is described below with reference to specific embodiments in conjunction with the accompanying drawings.

[0052] First, as Figure 1 As shown, some embodiments of the present application provide a low-carbon energy-saving air conditioning circulating liquid system, which includes a heat exchanger (not shown in the figure), a circulating liquid return pipe 11, a liquid separator 12, a heat dissipation device (not shown in the figure), a first container (not shown in the figure) and a liquid pump 14. The heat exchanger is used to exchange heat with the refrigerant in the compressor, and one end of the circulating liquid return pipe 11 is connected to the liquid outlet of the heat exchanger. The liquid separator 12 includes a plurality of liquid separators 121, and the other end of the circulating liquid return pipe 11 is connected to the liquid separator 121, and the liquid supply distance from the circulating liquid return pipe 11 to at least two liquid separators 121 is the same. The heat dissipation device is connected to the liquid separator 121, and is used to cool the liquid flowing out of the liquid separator 121. The first container is connected to the heat dissipation device, and is used to hold the liquid cooled by the heat dissipation device. One end of the liquid pump 14 is connected to the first container, and the other end is connected to the liquid inlet of the heat exchanger, and is used to pump the liquid in the first container to the heat exchanger.

[0053] In some embodiments, the heat exchanger may be a tubular heat exchanger or a plate heat exchanger, etc., and those skilled in the art may select and set it according to the needs of the specific application scenario. In some embodiments, the heat dissipation device may be a wet curtain, a heat dissipation fin tube, etc., and those skilled in the art may select and set it according to the needs of the specific application scenario. It should be noted that the structure of the heat dissipation structure and the setting of the heat exchanger belong to conventional settings in the field and will not be repeated here.

[0054] like Figures 1 to 3 As shown, in some embodiments, the circulating liquid return pipe 11 includes a circulating liquid return main pipe 111 and a plurality of liquid return branch pipes 112. One end of the circulating liquid return main pipe 111 is connected to the liquid inlet pipe 13. One end of the plurality of liquid return branch pipes 112 is connected to the other end of the circulating liquid return main pipe 111, and the other end of each liquid return branch pipe 112 is respectively connected to a liquid distribution tank 121, and the liquid supply distance from each liquid return branch pipe 112 to each liquid distribution tank 121 is the same.

[0055] like Figures 1 to 3 As shown, in some embodiments, the heat exchanger (not shown) is connected to the liquid inlet pipe 13 through the circulating liquid system outlet 17. The liquid inlet pipe 13 is connected to the circulating liquid return main pipe 111 through a flexible joint 18, which is convenient for installation and maintenance and replacement. A joint is provided at the end of the circulating liquid return main pipe 111, and the liquid return branch pipe 112 is connected to the circulating liquid return main pipe 111 through the joint.

[0056] In some embodiments, the material of the circulating liquid return pipe 11 is plastic, which is light, cheap, and easy to shape. Of course, the present application does not limit the material of the circulating liquid return pipe 11, and it can also be other materials, such as metal, carbon fiber or composite material.

[0057] In this way, the liquid supply distance between each liquid return branch pipe 112 and each liquid distribution tank 121 is the same, and the liquid supply can be evenly distributed to achieve uniform distribution of liquid such as water, ensure the water pressure balance of the circulating liquid system, and ensure the cooling effect of water. At the same time, it is beneficial to improve the refrigeration effect of low-carbon energy-saving air conditioners and reduce electricity consumption.

[0058] like Figure 2 and Figure 3 As shown, in some embodiments, the number of the liquid distribution tank 121 and the number of the liquid return branch pipe 112 are both 4. A five-way joint 113 is provided at the other end of the circulating liquid return main pipe 111, and each liquid return branch pipe 112 is connected to the circulating liquid return main pipe 111 through four joints distributed in a cross shape at the top of the five-way joint 113.

[0059] Of course, the number of liquid distribution tanks 121 and liquid return branches 112 can also be set to other numbers, such as 2 or 3, etc., and those skilled in the art can choose to set according to the needs of the application scenario, and this application does not limit this. The top of the five-way connector 113 can be set to other forms according to the needs of the application scenario, such as an "x" shape, and this application does not limit this.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments, the other end of each liquid return branch pipe 112 is provided with a three-way joint 114, and the three-way joint 114 is connected to the liquid separation tank 121. In this way, it is conducive to the smooth entry of water into the liquid separation tank 121. Of course, the other end of each liquid return branch pipe 112 may not be provided with a three-way joint 114, or may be provided with a joint of other forms, and the present application is not limited to this.

[0061] like Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the top of the liquid separation tank 121 is open. The liquid separation tank 121 includes: a first side wall 1211, a second side wall 1213, a third side wall 1213, a fourth side wall 1215 and a bottom plate 1216. The first side wall 1211 is arranged along the first direction, and a plurality of liquid separation ports 1212 are arranged on the first side wall 1211. The second side wall 1213 is arranged along the second direction, and the second side wall 1213 is connected to the first end of the first side wall 1211. The third side wall 1213 is arranged opposite to the second side wall 1213 and is connected to the second end of the first side wall 1211. The fourth side wall 1215 is arranged opposite to the first side wall 1211 and its two ends are connected to the second side wall 1213 and the third side wall 1213 respectively. The bottom plate 1216 is connected to the bottoms of the first side wall 1211, the second side wall 1213, the third side wall 1213 and the fourth side wall 1215. The first direction and the second direction have an angle, and the first direction is the length direction of the liquid separation groove 121. In some embodiments, the first direction and the second direction are perpendicular to the liquid separation groove 121. Of course, the first direction and the second direction may also have other angles.

[0062] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the plurality of liquid dispensing ports 1212 on the first side wall 1211 are evenly distributed along the first direction. In some embodiments, the first side wall 1211 is provided with a plurality of rows of liquid dispensing ports 1212 along the first direction. In some embodiments, the first side wall 1211 is provided with two rows of liquid dispensing ports 1212 along the first direction, and the two rows of liquid dispensing ports 1212 are respectively located at the top and the bottom of the first side wall 1211.

[0063] In this way, liquid separation (e.g., water separation) can be performed uniformly and smoothly at the same time through the two rows of liquid separation ports 1212 at the top and bottom of the first side wall 1211 of the liquid separation tank 121. Moreover, uniform water supply and water separation further ensure that the water pressure of the circulating liquid system is stable, which is beneficial to improving the refrigeration effect of the low-carbon energy-saving air conditioner and reducing power consumption. In addition, the design of multiple layers of liquid separation ports 1212, and the provision of multiple liquid separation ports 1212 on each layer, is beneficial to maintaining the sustainability of water circulation when there are impurities or partial blockages in the liquid separation ports 1212, avoiding electrical failures caused by blockages of the liquid separation ports 1212, and ensuring the safe operation of the low-carbon energy-saving air conditioner. In addition, the top of the liquid separation tank 121 is open, the structure is simple, easy to clean, and not easy to clog.

[0064] Of course, the number of rows of the liquid separation ports 1212 can also be other numbers, such as 3 rows, 4 rows or 5 rows, etc., and the present application does not limit this. The number of liquid separation ports 1212 can be selected and set as needed, and the present application does not limit this. In addition, the present application does not limit the shape of the liquid separation ports 1212, and those skilled in the art can choose to set it as needed. In addition, the liquid separation ports 1212 can also be set on the second side wall 1213, the third side wall 1213 or the fourth side wall 1215 as needed.

[0065] In some embodiments, the top of the first side wall 1211 is lower than the top of the fourth side wall 1215. In some embodiments, the tops of the second side wall 1213 and the third side wall 1213 are inclined surfaces. In this way, it is possible to ensure that water flows out from one side of the first side wall 1211, and to prevent water from flowing out from one side of the fourth side wall 1215 to cause pollution or equipment failure. Of course, the tops of the second side wall 1213 and the third side wall 1213 can also be set to other structures according to the needs of the application scenario.

[0066] In some embodiments, a sewage outlet 1217 is provided on the bottom plate 1216. Thus, the dirt in the liquid separation tank 121 can be conveniently discharged through the sewage outlet 1217 to avoid clogging of the liquid separation outlet 1212.

[0067] Of course, the bottom plate 1216 may not be provided with the sewage outlet 1217. In addition, the present application does not limit the number of the sewage outlets 1217, which may be one or other numbers, and those skilled in the art may select and set them as needed.

[0068] like Figure 4 and Figure 5 As shown, in some embodiments, the liquid separation tank 121 further includes a step plate 1218 and a support plate 1219. The step plate 1218 is connected to the bottom of the first side wall 1211, the second side wall 1213, and the third side wall 1213 and the bottom plate 1216.

[0069] like Figure 4 and Figure 5 As shown, in some embodiments, the liquid separation tank 121 further includes a support plate 1219. The support plate 1219 is connected between the step plate 1218 and the bottom plate 1216, and the support plate 1219, the bottom plate 1216, the second side wall 1213 and the third side wall 1213 enclose a receiving space. The step plate 1218 is arranged parallel to the bottom plate, and the height of the step plate 1218 is higher than the height of the bottom plate 1216, and the support plate 1219 is arranged vertically.

[0070] In this way, a holding space can be formed at the bottom of the liquid separation tank 121 to store a certain amount of water and ensure a stable water supply.

[0071] Of course, according to the needs of the application scenario, the step plate 1218 and / or the support plate 1219 may not be provided. Alternatively, the step plate 1218 and the support plate 1219 may also be provided along other directions.

[0072] In some embodiments, the low-carbon energy-saving air conditioning circulating fluid system 1 is also provided with an automatic cleaning system (not shown in the figure) for automatically and regularly cleaning the low-carbon energy-saving air conditioning circulating fluid system 1. In this way, the low-carbon energy-saving air conditioning circulating fluid system 1 can be avoided from being frequently disassembled, and the low-carbon energy-saving air conditioning circulating fluid system 1 can be cleaned conveniently and quickly. At the same time, it is ensured that the impurities in the low-carbon energy-saving air conditioning circulating fluid system 1 are cleaned in time to improve the circulating water efficiency, thereby ensuring the operating efficiency of the low-carbon energy-saving air conditioner.

[0073] like Figure 1 As shown, in some embodiments, the low-carbon energy-saving air conditioning circulating fluid system 1 is further provided with a fan 19 , which is arranged on the top of the liquid separator 12 and can dissipate the heat of the water in the liquid separator 12 .

[0074] It should be noted that the structure of the automatic cleaning system and other structures of the low-carbon energy-saving air-conditioning circulating fluid system 1 are conventional settings in the art and will not be described in detail here.

[0075] Based on the same inventive concept, in a second aspect, an embodiment of the present application further provides a low-carbon energy-saving air conditioner, which is provided with the low-carbon energy-saving air conditioner circulating fluid system 1 in the embodiment of the first aspect mentioned above.

[0076] The low-carbon energy-saving air conditioner of the present application has the corresponding technical effects of the above-mentioned low-carbon energy-saving air conditioner circulating fluid system 1, which will not be described in detail here. It should be noted that other structures of the low-carbon energy-saving air conditioner are conventional settings in the field, which will not be described in detail here.

[0077] Combine the following Figures 1 to 5 , the working principle of the low-carbon energy-saving air conditioning circulating liquid system 1 of the present application is described. During the operation of the low-carbon energy-saving air conditioner, water enters the circulating liquid system outlet 17 through the liquid outlet of the heat exchanger, and then enters the liquid inlet pipe 13, and enters the circulating liquid return main pipe 111 through the liquid inlet pipe 13. The water in the circulating liquid return main pipe 111 enters each liquid return branch pipe 112 through the five-way joint 113, and enters the liquid separation tank 121 through the three-way joint 114 at the end of the liquid return branch pipe 112. The water entering the liquid separation tank 121 enters the heat dissipation device through each liquid separation port 1212 for heat dissipation, and is then collected in the first container. The water in the first container is pumped to the liquid outlet pipe 15 by the liquid pump 14, and enters the heat exchanger through the circulating liquid system outlet 16.

[0078] The low-carbon energy-saving air conditioning circulating liquid system 1 and the low-carbon energy-saving air conditioning provided by the embodiment of the present application have the same liquid supply distance between the circulating liquid return pipe 11 and each liquid separation tank 121, which can realize equidistant and uniform liquid supply, so as to achieve uniform distribution of liquid such as water, and improve the cooling effect of liquid such as water, thereby ensuring the energy efficiency of the low-carbon energy-saving air conditioning. At the same time, the liquid separation tank 121 is open and the first side wall 1211 of the liquid separation tank 121 is provided with a multi-layer liquid separation port 1212, which is conducive to avoiding waterway blockage, or in the state where the liquid separation port 1212 has impurities or partial blockage, to ensure continuous and stable water circulation, thereby avoiding electrical failures caused by blockage of the liquid separation port 1212, etc., and ensuring the safe operation of the low-carbon energy-saving air conditioning. In addition, the top of the liquid separation tank 121 is open, the structure is simple, easy to clean, and not easy to block. In addition, an automatic cleaning system is also provided in the low-carbon energy-saving air conditioning circulating liquid system 1, which is convenient for automatic and timed cleaning of the low-carbon energy-saving air conditioning circulating liquid system 1.
