Detailed Implementation
[0017] To more clearly illustrate the overall concept of the present invention, a detailed description will be provided below with reference to the accompanying drawings and examples. Example 1:
[0018] Please see Figures 1 to 9 This invention provides a technical solution: a central air conditioning cooling capacity balanced distribution energy-saving device, comprising: The first tube 1 has an inlet 2 and a second tube 3 connected to its two ends respectively, and the second tube 3 has a diversion hole 301. The turbulence-disrupting component 9 is disposed inside the first tube 1 to turbulent the refrigerant entering the first tube 1, thereby mixing the gas and liquid phases. Cleaning component 4 is disposed inside the diversion hole 301 and is used to clean the inside of the diversion hole 301; The inlet 2 is connected to the second pipe 3 through the first pipe 1. The refrigerant enters the interior of the first pipe 1 through the inlet 2 and is disturbed and mixed by the turbulence component 9 inside the first pipe 1. Then it is evenly discharged through the diversion hole 301. The cleaning component 4 is designed to clean the dust adhering to the inner wall of the diversion hole 301, preventing dust or impurities from changing the thickness of the inner wall of the diversion hole 301 and thus affecting the flow rate of the gas flowing through the diversion hole 301. Example 2:
[0019] like Figures 2-3 As shown, the central air conditioning cooling capacity equalization and energy-saving device disclosed in Embodiment 2 of the present invention has a structure that is basically the same as that in Embodiment 1, except that: The first tube body 1 has a cavity 101 and a connecting cavity 102 formed inside, and the cavity 101 and the cavity 102 are connected. The liquid inlet 2 is screwed into the connecting cavity 102, and the second tube 3 is screwed into the cavity 101; A spiral plate 5 is provided inside the end of the liquid inlet 2 away from the first tube body 1. The distance between the outer wall and the inner wall of the spiral plate 5 is greater than the inner diameter of the liquid inlet 2. A through hole is opened on the rear surface of the spiral plate 5. The inlet 2 is provided with at least one set of liquefaction plates 6, which are located at the end of the spiral plate 5 facing the cavity 101. An annular guide plate 7 is provided inside the liquid inlet 2 at one end facing the cavity 101. A through hole 8 is provided at the end of the guide plate 7. The liquid inlet 2 is connected to the first tube 1 through the through hole 8. The inner diameter of the through hole 8 is smaller than the inner diameter of the liquid inlet 2; A spiral plate 5 is installed inside the liquid inlet 2. The spiral plate 5 enables the refrigerant to change from a straight flow to a rotating flow in the liquid inlet 2. The rotating flow realizes a variety of physical effects such as centrifugation, shearing, and turbulence, which work together to ultimately achieve a gas-liquid mixing effect. The through holes on the spiral plate 5 can cut air bubbles, making the gas-liquid mixing more uniform. The design of the guide plate 7 and the through hole 8 allows the refrigerant to flow from the large channel to the small channel, changing the flow efficiency and making the gas and liquid mix better. Example 3:
[0020] like Figures 3-6 As shown, the central air conditioning cooling capacity equalization and energy-saving device disclosed in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiment 2, except that: An installation plate 10 is provided inside the cavity 101, and the installation plate 10 is located between the liquid inlet 2 and the second tube 3; The turbulence assembly 9 includes a second rotating shaft 901, one end of which is fitted with a limiting ring 905.

One end of the abutting rod 911 away from the shelf 908 passes through the limiting ring 905 and is connected to the lower end of the second limiting groove 912. When the refrigerant flows through the through hole 8, the pressure increases, which drives the turbulence component 9 to rotate. The flexible guide cloth 903 on the turbulence component 9 is set at an angle, which can change the direction of gas-liquid mixing flow and increase the mixing effect. The positions of each second connecting rod 904 can be changed by the cooperation of the electric telescopic mechanism 907 and the abutment rod 911, thereby changing the tilt angle of the corresponding flexible guide cloth 903, and thus changing the gas-liquid two-phase flow time and the mixing time. Example 4:
[0021] like Figures 7-9 As shown, the central air conditioning cooling capacity equalization and energy-saving device disclosed in Embodiment 4 of the present invention has a structure that is basically the same as that in Embodiment 3, except that: Multiple sets of diversion holes 301 are provided, and the multiple sets of diversion holes 301 are evenly spaced apart. The cleaning component 4 includes a second collar 402 installed on the inner wall of each of the diversion holes 301. The inner wall of the second collar 402 is provided with a first limiting groove 403. Multiple sets of circumferentially distributed sliders 404 are rotatably arranged inside the first limiting groove 403. The cleaning component 4 also includes a first rotating shaft 401 disposed at the center of each of the diversion holes 301, the outer surface of the first rotating shaft 401 being connected to the end of each of the sliders 404 away from the second collar 402; Both ends of the first rotating shaft 401 are provided with a first guide plate 406, and multiple sets of the first guide plate 406 are provided, and the multiple sets of the first guide plate 406 are distributed in a circle. A support rod 405 is provided on the outer surface of the first rotating shaft 401 at the end position of each of the first guide plates 406, and the end of each first guide plate 406 is connected to the corresponding support rod 405.

The end of the first rotating shaft 401 at the center position is connected to the lower end of the limiting ring 905; The cleaning component 4 can rotate inside the diversion hole 301 through the limiting ring 905 to clean the impurities adhering to the inner wall of the diversion hole 301, prevent impurities from adhering to the inner wall of the diversion hole 301, causing different inner diameters of each diversion hole 301, affecting the flow rate of the refrigerant, and achieving uniform flow rate in each diversion hole 301. The first guide plate 406 is inclined to guide the gas-liquid two-phase flow and further enhance the mixing of gas and liquid.
[0022] Specifically, this scheme involves connecting the inlet 2 and the second pipe 3 through the first pipe 1. The refrigerant enters the interior of the first pipe 1 through the inlet 2. A spiral plate 5 is installed inside the inlet 2. The spiral plate 5 transforms the refrigerant flow from straight flow to rotating flow in the inlet 2. The rotating flow achieves various physical effects such as centrifugation, shearing, and turbulence, which work synergistically to ultimately achieve gas-liquid mixing. The through holes on the spiral plate 5 can cut air bubbles, making the gas-liquid mixing more uniform. The arrangement of the guide plate 7 and the through hole 8 allows the refrigerant to flow from the large channel to the small channel, changing the flow efficiency and making the gas and liquid more mixed. At the same time, the pressure increases when passing through, pushing the turbulence component 9 to rotate. The flexible guide cloth 903 on the turbulence component 9 is set at an angle, which can change the direction of gas-liquid mixing flow and increase the mixing effect. When the limiting ring 905 rotates, it drives the cleaning component 4 to rotate inside the diversion hole 301, cleaning the impurities adhering to the inner wall of the diversion hole 301, preventing impurities from adhering to the inner wall of the diversion hole 301, causing different inner diameters of each diversion hole 301, affecting the flow rate of the refrigerant, and achieving uniform flow in each diversion hole 301.
