It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air-conditioning system to offset the heat load of the indoor environment. The heating system provides the required heat for the air-conditioning system to offset the cooling and heating load of the indoor environment. It is mainly used to adjust the temperature and humidity in large buildings or houses to provide a comfortable indoor environment and help evenly distribute cold and hot air in a large space.

[0003] After retrieval, the text of the patent number "CN218120116U" mentions that "the utility model relates to the technical field of central air conditioners, and discloses a dual-mode subcooling structure for a central air conditioner, including a first heat exchanger. The compressor is fixedly connected to a second four-way reversing valve through a pipeline. One end of the second four-way reversing valve away from the compressor is provided with a first heat exchanger.

The unit can achieve subcooling of high-temperature liquid and superheating of low-temperature gas in both the refrigeration and heating modes, ensuring that the unit has good performance in both dual modes and effectively solving the problem of low energy efficiency of the unit." When in use, through the cooperation among the first four-way reversing valve, the second four-way reversing valve, the compressor and the plate heat exchanger, and by using the installation of the four-way reversing valve, the function of mutually switching and operating the refrigeration and heating modes of the central air conditioner is realized, effectively solving the problem of low energy efficiency of the unit. The unit can achieve subcooling of high-temperature liquid and superheating of low-temperature gas in both the refrigeration and heating modes, ensuring that the unit has good performance in both dual modes. However, the way of using it for refrigeration is relatively single, lacking multiple modes to adapt to different refrigeration requirements.

[0004] Therefore, we provide a dual-mode subcooling structure for a central air conditioner to solve the above problems. Content of the Utility Model

[0005] This application provides a dual-mode subcooling structure for a central air conditioner, which solves the problem that the way of using it for refrigeration is relatively single and lacks multiple modes to adapt to different refrigeration requirements.

[0006] This application provides a dual-mode subcooling structure for a central air conditioner, including a main body and a conversion mechanism. The conversion mechanism is arranged on the outer side of the main body;

[0007] The conversion mechanism includes a working component installed inside the main body. An adjusting component is installed at the top end of the working component, a connecting component is installed at the bottom end of the working component, a subcooling component is installed on one side of the adjusting component, and a cooling component is arranged outside the subcooling component.

[0008] Preferably, the working component includes a disc-shaped pipe installed inside the main body. An indoor fan is arranged on one side of the disc-shaped pipe, and ventilation slots are formed on both sides of the main body.

[0009] Preferably, the adjusting component includes a bifurcated pipe arranged at the top end of the disc-shaped pipe, and a regulating valve is installed outside the bifurcated pipe.

[0010] Preferably, the connecting component includes a connecting pipe fixed at the bottom end of the disc-shaped pipe, and connecting valves are installed at both ends of the connecting pipe.

[0011] Preferably, the subcooling component includes a booster pump whose pipe is connected to one end of the regulating valve, and a heat exchange pipe is installed at the bottom end of the booster pump.

[0012] Preferably, the cooling component includes a heat exchange box fixed outside the heat exchange pipe, and a refrigerating machine is connected to one side of the heat exchange box through a pipe.

[0014] As can be seen from the above technical solutions, the present application provides a dual-mode subcooling structure for a central air conditioner. When in use, first, under the requirement of low energy consumption, open the regulating valve and the connecting valve on the side of the cooling component, start the indoor fan to rotate reversely, drive the hot air to flow towards the disc-shaped pipe for heat exchange, inject the hot water in the disc-shaped pipe into the cooling box through the water pump, and then the cooling fan enhances the cooling efficiency of the hot water in the cooling box. This mode has low energy consumption and weak cooling capacity. Then, when it is necessary to switch to a more forced cooling mode, open the regulating valve and the connecting valve on the side of the subcooling component, drive the coolant in the heat exchange pipe to flow through the bifurcated pipe through the booster pump, enter the disc-shaped pipe, cool the air inside the main body, and blow out cold air through the indoor fan. The refrigerating machine cools the heat exchange box through a pipe to make the cooling cycle. This mode has high energy consumption and strong cooling capacity, and completes the switching and use of the cooling mode.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. Switch the cooling mode through the conversion mechanism to adapt to different environmental requirements. The coil-type tube is connected to different cooling systems through the opening and closing of the regulating valve and the connecting valve on the same side. The booster pump drives the coolant of the heat exchange tube to flow through the bifurcated pipes and enter the coil-type tube to cool the air inside the main body. The indoor fan blows out the cold air. The refrigerator cools the heat exchange box through the pipe to make the cooling cycle. This mode has high energy consumption and strong cooling capacity.

[0017] 2. The indoor fan rotates in reverse to drive the hot air to flow to the coil-type tube for heat exchange. The hot water from the coil-type tube is injected into the cooling box through the water pump. The cooling fan enhances the cooling efficiency of the hot water in the cooling box. This mode has low energy consumption and weak cooling capacity.

[0018] In summary, the present application can switch the refrigeration mode through the conversion mechanism to adapt to different environmental requirements, and can control excessive energy consumption and save energy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] See Figures 1-4 Figures 1-4 , a dual-mode subcooling structure for a central air conditioner, including a main body 1 and a conversion mechanism 2. The conversion mechanism 2 is arranged outside the main body 1, and the refrigeration mode is switched through the conversion mechanism 2 to adapt to different environmental requirements;

[0027] The conversion mechanism 2 includes a working component 21 installed inside the main body 1. The working component 21 directly exchanges indoor heat to complete heat exchange. An adjustment component 22 is installed at the top of the working component 21 to control the conversion of the refrigeration mode. A connection component 23 is installed at the bottom of the working component 21 to form a cycle through the connection component 23. A subcooling component 24 is installed on one side of the adjustment component 22 to complete efficient heat conversion. A cooling component 25 is arranged outside the subcooling component 24 to complete efficient refrigeration.

[0028] In the present utility model, the working component 21 includes a disk-shaped pipe 211 installed inside the main body 1, which directly exchanges heat with indoor air through the disk-shaped pipe 211. An indoor fan 212 is arranged on one side of the disk-shaped pipe 211 to strengthen air circulation. Ventilation slots 213 are opened on both sides of the main body 1 to facilitate air circulation and isolate certain sundries through the ventilation slots 213.

[0029] In the present utility model, the adjustment component 22 includes a bifurcated pipe 221 arranged at the top of the disk-shaped pipe 211, which provides a multi-directional flow guiding function. A regulating valve 222 is installed outside the bifurcated pipe 221 to control the flow guiding direction of the bifurcated pipe 221.

[0030] In the present utility model, the connection component 23 includes a connection pipe 231 fixed at the bottom of the disk-shaped pipe 211, which forms a circulation structure with other components through the connection pipe 231. Connection valves 232 are installed at both ends of the connection pipe 231 to control the flow guiding direction of the connection pipe 231.

[0031] In the present utility model, the subcooling component 24 includes a booster pump 241 whose pipeline is connected to one end of the regulating valve 222. The booster pump 241 drives the coolant in the heat exchange pipe 242 to flow. The heat exchange pipe 242 is installed at the bottom of the booster pump 241, and the coolant is circulated and cooled through the heat exchange pipe 242.

[0032] In the present utility model, the cooling component 25 includes a heat exchange box 251 fixed outside the heat exchange pipe 242. The cooling medium in the heat exchange box 251 cools the coolant in the heat exchange pipe 242. A refrigerating machine 252 is pipeline-connected to one side of the heat exchange box 251 to provide a refrigerating function.

[0033] In some embodiments, a cooling component 3 is installed at the other end of the regulating valve 222 to provide another cooling mode. The cooling component 3 includes a water pump 31 whose pipeline is connected to the other end of the regulating valve 222. The hot water in the disk-shaped pipe 211 is injected into the cooling tank 32 by the water pump 31. The bottom end of the water pump 31 is fixedly connected to the cooling tank 32, and the cooling tank 32 stores the hot water for heat dissipation. A cooling fan 33 is arranged on one side of the water pump 31, and the cooling fan 33 enhances the cooling efficiency of the hot water in the cooling tank 32.

[0034] As can be seen from the above technical solutions, during use, first, under the requirement of low energy consumption, the regulating valve 222 and the connecting valve 232 on one side of the cooling component 3 are opened, and the indoor fan 212 is started to rotate reversely to drive the hot air to flow towards the disk-shaped pipe 211 for heat exchange. The hot water in the disk-shaped pipe 211 is injected into the cooling tank 32 by the water pump 31. Then, the cooling fan 33 enhances the cooling efficiency of the hot water in the cooling tank 32. This mode has low energy consumption and weak cooling capacity. When a stronger cooling mode needs to be switched later, the regulating valve 222 and the connecting valve 232 on one side of the subcooling component 24 are opened, and the coolant in the heat exchange pipe 242 is driven to flow through the bifurcated pipeline 221 by the booster pump 241 and enters the disk-shaped pipe 211 to cool the air inside the main body 1. The cold air is blown out through the indoor fan 212. The refrigerating machine 252 cools the heat exchange tank 251 through the pipeline to make the cooling cycle. This mode has high energy consumption and strong cooling capacity, and the switching use of the cooling mode is completed.
