Description

Technical Field

[0001] This utility model relates to the field of absorption air conditioning, and in particular to an absorption air conditioning heat absorption device. Background Technology

[0002] In an absorption air conditioner, the heart of the unit is the generator-absorber assembly, which consumes heat energy (such as steam, hot water, or gas flames) to complete a process similar to "compression." The absorption components work by utilizing changes in the concentration of an internal lithium bromide solution to absorb or release heat, thus achieving heat transfer.

[0003] The current absorption components include a cavity for containing the lithium bromide solution and a recovery pipe for inputting the lithium bromide solution. After entering the cavity, the vapor comes into contact with the lithium bromide solution and is absorbed. However, the contact surface between the two is basically the entire surface of the lithium bromide solution, resulting in low absorption efficiency and slow heat absorption, which in turn affects the heat transfer efficiency of the heat exchange tube.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this invention is to provide an absorption-type air conditioning heat absorption device that changes the center of the mixing process between lithium bromide solution and steam from the traditional bottom liquid surface mixing to the mixing during the dripping process, and changes the traditional liquid surface contact to the contact of several liquid droplet surfaces, which greatly increases the mixing area between lithium bromide solution and steam, improves the mixing efficiency, and further improves the cooling efficiency.

[0006] To achieve the above objectives, this utility model provides an absorption-type air conditioning heat absorption device, comprising: a shell having an internal chamber filled with a lithium bromide solution; a steam inlet on the side wall of the shell; a heat exchange tube installed in the chamber; a heat exchange medium flowing inside the heat exchange tube; a solution recovery component installed in the chamber, including several conduits extending along a first direction and support members connected to the ends of the conduits, the conduits being connected to a solution input pipe; a release port communicating with the interior of the conduits being provided on the outer wall of the conduits; and a solution outlet located at the bottom of the shell.

[0007] According to the present invention, the support member of the absorption-type air conditioning heat absorption device is a disc-shaped structure; the top disc surface of the support member is connected to the shell through a bracket, and the bottom disc surface is connected to the end of the conduit.

[0008] According to the present invention, the heat absorption device for an absorptive air conditioner has a rotating structure with a high center and low periphery on the top plate of the support member.

[0009] According to the present invention, the support member is hollow inside, and its internal space is connected to the internal space of several conduits; the support member is connected to the solution input pipe.

[0010] According to the present invention, the heat exchange tube of the absorption-type air conditioning heat absorption device is a spiral coil; the central axis of the spiral coil is parallel to the first direction.

[0011] According to the present invention, the axial direction of the spiral coil and the extension direction of the duct are both vertical.

[0013] According to the present invention, in the absorption-type air conditioning heat absorption device, the cross-sectional diameter of the duct decreases sequentially from top to bottom.

[0014] This utility model provides an absorption-type air conditioning heat absorption device, comprising: a shell with an internal chamber; the shell is a tank structure filled with lithium bromide solution; a steam inlet is provided on the side wall of the shell. A heat exchange tube is installed inside the chamber; a heat exchange medium, such as water or other media, flows inside the heat exchange tube; the heat exchange tube partially extends outside the shell and connects to other equipment, such as an evaporator.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0020] See Figure 1 This utility model provides an absorption-type air conditioning heat absorption device, which includes: The shell 1 has an internal chamber; the shell 1 is a tank structure and is filled with lithium bromide solution; a steam inlet is provided on the side wall of the shell 1.

[0021] Heat exchange tube 2 is installed in the chamber; heat exchange medium, such as water or other medium, flows inside the heat exchange tube; the heat exchange tube 2 extends partially outside the shell 1 and is connected to other equipment, such as an evaporator.

[0022] The solution recovery component 3 is installed in the chamber and includes several conduits 31 extending along a first direction and support members 32 connected to the ends of the conduits 31. The interior of the several conduits 31 is connected to a solution input pipe 33. The outer wall of the conduits 31 is provided with a release port that connects to the interior of the conduits 31.

[0023] See Figure 2 The solution outlet 4 is located at the bottom of the shell 1, and the lithium bromide solution is discharged from the equipment through the solution outlet 4. The solution outlet 4 is connected to the pump body 5 and the auxiliary heat exchanger 6 through a pipe, and one of the interfaces of the auxiliary heat exchanger is connected to the solution input pipe 33.

[0024] During operation, the steam released by the evaporator enters the absorption equipment through the steam inlet. The lithium bromide solution inside the shell 1 absorbs the steam and simultaneously absorbs the heat inside the shell 1. At the same time, the heat of the heat exchange medium flowing in the heat exchange tube 2 is also absorbed by the lithium bromide solution, the temperature of the heat exchange medium in the heat exchange tube 2 decreases, and the lithium bromide solution changes from a high concentration state to a low concentration state.

[0025] A low-concentration lithium bromide solution is pumped by pump body 5 to auxiliary heat exchanger 6. Auxiliary heat exchanger 6 heats the low-concentration lithium bromide solution through internal heat exchange tube 2, thereby evaporating the internal water and reducing the concentration. The lithium bromide solution changes from a low-concentration state to a high-concentration state, and then is reintroduced into the shell 1 through solution input pipe 33.

[0026] Based on the above, in order to improve the fusion efficiency of steam with lithium bromide solution after entering shell 1.

[0027] This application uses a solution recovery component 3 to solve the above problems. When a high-concentration lithium bromide solution is reintroduced into the equipment through the solution input pipe 33, it is dispersed into the conduit 31 and further drips from the release port.

[0028] During the dripping process, the high-concentration lithium bromide solution is remixed with the vapor to become a low-concentration lithium bromide solution, which eventually collects at the bottom of the casing 1. This application, through the above structure, changes the focus of the mixing process between the lithium bromide solution and vapor from the traditional bottom-surface mixing (mixing with vapor only after collecting at the bottom of the casing 1) to mixing during the dripping process. It also changes the traditional surface contact to contact between several droplets, greatly increasing the mixing area between the lithium bromide solution and vapor, improving mixing efficiency, and further enhancing cooling efficiency.

[0029] In some embodiments of this application, the support member 32 is a disc-shaped structure; the top disc surface of the support member 32 is connected to the housing 1 via a bracket, and the bottom disc surface is connected to the end of the conduit 31. To ensure a stable connection between the support member 32 and the conduit 31, the support member 32 is set in a disc shape, which can have a larger supporting surface and ensure stable support for multiple conduits 31.

[0030] In some embodiments of this application, the support member 32 has a rotating structure with a high center and low edges on its top surface. The support member 32 of this application has a better flow guiding effect, allowing water droplets condensed on its top surface to slide off under gravity.

[0031] In some embodiments of this application, the support member 32 is hollow inside, and its internal space communicates with the internal space of a plurality of conduits 31; the support member 32 is connected to the solution inlet pipe 33. The support member 32 acts as a distributor, which can perform liquid diversion. At this time, only a single solution inlet pipe 33 needs to be connected to the support member 32, and the support member 32 can disperse the lithium bromide solution into multiple conduits 31.

[0032] In some embodiments of this application, the heat exchange tube 2 is a spiral coil. To achieve a reasonable structural distribution and compact structure, the central axis of the spiral coil is parallel to the first direction. Using a spiral coil can increase the contact area between the heat exchange tube 2 and the internal space of the shell 1, thus achieving sufficient heat exchange. Preferably, the central axis of the spiral coil and the extension direction of the conduit 31 are both vertical. The spiral coil is disposed close to the inner wall of the shell 1 and surrounds a placement space inside; several conduits 31 are disposed within the placement space.

[0033] In some embodiments of this application, the cross-sectional diameter of the conduit 31 decreases sequentially from top to bottom, which facilitates the dripping of droplets under the action of gravity and prevents droplets flowing out of the release port from flowing along the outer wall of the pipe, thereby affecting the contact between the solution droplets and the vapor.

[0034] In summary, this utility model provides an absorption-type air conditioning heat absorption device, comprising: a shell with an internal chamber; the shell is a tank structure filled with lithium bromide solution; a steam inlet is provided on the side wall of the shell. A heat exchange tube is installed inside the chamber; a heat exchange medium, such as water or other media, flows inside the heat exchange tube; the heat exchange tube partially extends outside the shell and connects to other equipment, such as an evaporator. A solution recovery component is installed inside the chamber, including several conduits extending in a first direction and support members connected to the ends of the conduits; the conduits are internally connected to a solution input pipe; a release port communicating with the interior of the conduits is provided on the outer wall of the conduits. A solution outlet is located at the bottom of the shell; the lithium bromide solution is discharged from the device through the solution outlet; the solution outlet is connected to a pump and an auxiliary heat exchanger via a pipe, and one interface of the auxiliary heat exchanger is connected to the solution input pipe. During operation, steam released by the evaporator enters the absorption device through the steam inlet. The lithium bromide solution inside the shell absorbs the steam, simultaneously absorbing heat from the shell's interior. At the same time, the heat of the heat exchange medium flowing through the heat exchange tubes is also absorbed by the lithium bromide solution, causing the temperature of the heat exchange medium inside the tubes to decrease, and the lithium bromide solution to transition from a high-concentration state to a low-concentration state. This invention changes the core of the mixing process between the lithium bromide solution and steam from the traditional bottom-level mixing to mixing during the dripping process, and from traditional surface contact to contact between multiple droplets, greatly increasing the mixing area between the lithium bromide solution and steam, improving mixing efficiency, and further enhancing cooling efficiency.

[0035] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
