Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air conditioning, in particular to a novel air conditioning evaporation system. Background Art
[0002] Existing evaporators utilize liquid refrigerant to absorb heat from the copper tubes and fins through instantaneous evaporation. This instantaneous heat absorption can transfer heat to temperatures below 0 degrees Celsius. Air conditioning creates cold air by using an electronic fan to blow air through the evaporator, utilizing the heat absorption of the copper tubes and fins inside the evaporator to absorb the heat from the air, thereby producing cold air. The evaporator's cooling air is generally around 10 degrees Celsius, while the evaporator surface is around 0 degrees Celsius (manufactured internally below 0 degrees Celsius). 0 degrees Celsius prevents ice from forming on the evaporator surface, but it does produce a lot of condensation. With an evaporator surface temperature of 0 degrees Celsius and the cold air blown out at around 10 degrees Celsius, there's still significant room for lowering the temperature, but this cannot be conducted through air. This temperature gap results in a waste of cooling resources. Utility Model Content

[0019] The present invention will be further described and explained below in conjunction with specific embodiments and accompanying drawings:
[0020] Please refer to Figure 1 and Figure 2 A new type of air-conditioning evaporation system includes a first chassis 10 and an insulated water tank 20. The front and rear sides of the first chassis 10 are open. An evaporator 12 is provided at the opening on the front side of the first chassis 10. A first fan 11 is provided in the first chassis 10. The output end of the first fan 11 is set toward the evaporator 12. A pipe row group 13 is provided between the first fan 11 and the evaporator 12. The pipe row group 13 and the evaporator 12 are close to each other on one side. A first water pump 14 is provided between the pipe row group 13 and the insulated water tank 20. A first water inlet 131 and a first water outlet 132 are provided on the pipe row group 13. The first water inlet 131 is connected to the output end of the first water pump 14 through a first insulation pipe 15. The input end of the first water pump 14 is connected to the insulated water tank 20. The first water outlet 132 is connected to the insulated water tank 20 through a second insulation pipe 16.
[0021] In the above scheme, the evaporator 12 is connected to the high-pressure liquid pipeline of the air conditioner, and the high-pressure liquid refrigerant in the narrow pipeline is sprayed into the evaporator 12, causing the refrigerant to change in space. The high-pressure liquid refrigerant instantly expands and becomes a low-pressure gaseous refrigerant. During this physical change, the refrigerant will absorb a lot of heat through the evaporator 12, thereby making the evaporator 12 and the tube group 13 that are close to each other become very cold. At the same time, the first fan 11 blows air toward the tube group 13 and the evaporator 12, and the cold tube group 13 and the evaporator 12 contact with the air for heat exchange, thereby generating cold air. At the same time, the first water pump 14 draws water from the insulated water tank 20 into the tube group 13 for water circulation. The heat exchange capacity of water is higher than that of air. During the water circulation process, the water will exchange heat with the cold tube group 13, thereby forming cold water flowing into the insulated water tank 20, storing cold energy, and not affecting the generation of cold air, thereby avoiding waste of cold source. When there is sufficient cold water stored in the insulated water tank 20, the injection of the refrigerant can be suspended. Through the circulation of the cold water, heat exchange is carried out with the adjacent tube group 13 and the evaporator 12, so that the tube group 13 and the evaporator 12 become cold, and cooperate with the first fan 11 to generate cold air, thereby saving energy.
[0022] Please refer to Figure 2The evaporator 12 includes a hollow first frame 121, which is provided with a refrigerant interface 122. A plurality of first flat tubes 123 are evenly spaced within the first frame 121 and are in communication with the first frame 121. The tube array 13 includes a hollow second frame 133, with a first water inlet 131 and a first water outlet 132 both located within the second frame 133. The second frame 133 and the first frame 121 are adjacent to each other. Second flat tubes 134 are located within the second frame 133 at positions corresponding to the first flat tubes 123. The plurality of second flat tubes 134 are in communication with the second frame 133 and are adjacent to each other. Furthermore, the second frame 133 and the first frame 121 have the same shape, and the second flat tubes 134 and the first flat tubes 123 have the same shape. The first flat tubes 123 are provided with first fin rows 124.
[0023] In the above scheme, refrigerant is injected from refrigerant port 122 into multiple parallel first flat tubes 123, causing a spatial change in the refrigerant. The high-pressure liquid refrigerant instantly expands and becomes a low-pressure gaseous refrigerant. During this physical change, the refrigerant absorbs a large amount of heat through the first flat tubes 123, causing the first frame 121, the first flat tubes 123, the second frame 133, the second flat tubes 134, and the first fin row 124 to become very cold. This, in conjunction with the first fan 11, generates cold air and the water circulation system produces cold water. The provision of the first fin row 124 increases the contact area between the evaporator 12 and the air, improving heat exchange efficiency. Furthermore, the identically shaped first frame 121 and second frame 133, and the first flat tubes 123 and second flat tubes 134, increase the contact area and enhance heat transfer.
[0024] Please refer to Figure 4 A heater 21 is provided in the thermal insulation water tank 20 .
[0025] In the above solution, the heater 21 can heat the water in the thermal water tank 20. In cold weather, hot water can be circulated to generate warm air in conjunction with the first fan 11. In this embodiment, the heater 21 is a spiral structure, which can increase the contact area with the water and improve the heating efficiency.
[0026] Please refer to Figure 1 and Figure 3, and also includes a second chassis 30, the front and rear sides of the second chassis 30 are open, a heat exchanger 32 is provided at the front opening of the second chassis 30, a second fan 31 is provided in the second chassis 30, the output end of the second fan 31 is arranged toward the heat exchanger 32, a second water pump 33 is provided between the heat exchanger 32 and the insulated water tank 20, a second water inlet 322 and a second water outlet 323 are provided on the heat exchanger 32, the second water inlet 322 is connected to the output end of the second water pump 33 through a third insulation pipe 34, the input end of the second water pump 33 is connected to the insulated water tank 20, and the second water outlet 323 is connected to the insulated water tank 20 through a fourth insulation pipe 35.
[0027] In this solution, the second housing 30 can be placed elsewhere. The second water pump 33 circulates cold water between the heat exchanger 32 and the insulated water tank 20, and the second fan 31 generates cold air, allowing the same air conditioner to be used in multiple scenarios. Specifically, the third and fourth insulated tubes 34, 35 are both detachable and can be selected in length based on specific usage scenarios to meet diverse needs.
[0028] In addition, the setting of the second chassis 30 also has a new purpose. Starting the first water pump 14 and the second water pump 33 at the same time will cause the water inside the heat exchanger 32 and the tube array 13 to mix with each other inside the insulated water tank 20, thereby achieving temperature synchronization between different areas. For example, if the first chassis 10 is set indoors and the second chassis 30 is moved outdoors, temperature synchronization of the two scenes can be achieved.
[0029] Please refer to Figure 3 The heat exchanger 32 includes a third flat tube 321, which is serpentine-shaped. The second water inlet 322 is provided at one end of the third flat tube 321, and the second water outlet 323 is provided at the other end of the third flat tube 321. Furthermore, a plurality of second fin rows 324 are provided at intervals on the third flat tube 321.
[0030] In the above solution, the serpentine third flat tube 321 cooperates with the second fin row 324 to effectively increase the contact area between the heat exchanger 32 and the air, thereby improving the heat exchange efficiency and ensuring the generation of cold air.
[0031] The utility model provides a novel air-conditioning evaporation system, in which the evaporator is connected to the high-pressure liquid pipeline of the air conditioner, and the high-pressure liquid refrigerant in the narrow pipeline is sprayed into the evaporator, causing the refrigerant to change in space, and the high-pressure liquid refrigerant instantly expands and becomes a low-pressure gaseous refrigerant. During this physical change, the refrigerant will absorb a lot of heat through the evaporator, thereby making the evaporator and the tube group that are close to each other become very cold, and at the same time, a first fan blows air toward the tube group and the evaporator, and the cold tube group and evaporator are in contact with the air for heat exchange, thereby generating cold air, and at the same time, a first water pump draws water from the insulated water tank into the tube group for water circulation. The heat exchange capacity of water is higher than that of air. During the water circulation process, water will exchange heat with the cold tube group, thereby forming cold water that flows into the insulated water tank, stores cold energy, does not affect the generation of cold air, and avoids waste of cold source. When there is sufficient cold water stored in the insulated water tank, the injection of refrigerant can be suspended. The cold water circulates and exchanges heat with the adjacent tube group and evaporator, making the tube group and evaporator cold, and cooperates with the first fan to generate cold air, thereby saving energy.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
