Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, specifically relating to a water-cooled solution temperature-regulating air conditioning unit. Background Technology

[0002] Solution-based temperature-controlled air conditioning units are an environmental control technology based on direct heat and humidity exchange between a salt solution and air. It originated from the need for an energy-saving and environmentally friendly alternative to traditional refrigerant-based air conditioning. Traditional air conditioning relies on compressor cooling and condensation dehumidification, which suffers from high energy consumption, susceptibility to mold growth, and limited control precision. Solution-based temperature control technology, by adjusting the solution concentration and temperature, can independently and precisely control the temperature and humidity of the air, avoiding the waste of reheat energy. Combined with heat pump technology to achieve solution regeneration, it significantly improves energy efficiency.

[0003] However, a significant problem exists in the actual operation of widely used water-cooled solution-based temperature control air conditioning units: the solution circulating inside the unit continuously evaporates and is lost during operation, leading to a gradual decrease in the total solution volume. Actual measurements show that a standard water-cooled solution-based temperature control air conditioning unit requires an average of over 10 liters of distilled or deionized water to maintain normal operation during 24 hours of continuous operation. Currently, the common method of water replenishment in the industry is for operators to manually open the water valve after the unit is shut down. This manual water replenishment method is not only inefficient, but more importantly, as the solution continues to evaporate, the relative concentration of the solute in the solution continuously increases, triggering a series of adverse physicochemical changes: the solution viscosity increases significantly, reducing fluidity; the boiling point rises abnormally, affecting heat exchange efficiency; the freezing point drops abnormally; the electrical conductivity of the solution also changes significantly; and, more seriously, the corrosiveness of the solution to metal components increases dramatically. These changes in properties caused by concentration variations can severely affect the stability of the solution, leading to a decrease in the heat exchange efficiency and temperature regulation performance of the air conditioning unit, and ultimately affecting the operation and service life of the entire air conditioning system.

[0010] Preferably, the top of the casing is provided with a fresh air outlet, a dehumidifier fan connection port, an exhaust port, and a regenerator fan connection port.

The first exhaust chamber is located at the bottom of the fresh air outlet, the first air inlet chamber is located at the bottom of the dehumidifier fan connection port, the second exhaust chamber is located at the bottom of the exhaust port, and the second air inlet chamber is located at the bottom of the regenerator fan connection port.

[0011] Preferably, a first packed tower is installed in the first exhaust chamber, a first heat exchanger is installed in the first air inlet chamber, a second packed tower is installed in the second exhaust chamber, and a second heat exchanger is installed in the second air inlet chamber.

[0012] Preferably, a first solution pump and a second solution pump are respectively installed at the bottom of the inner cavity.

[0014] In the above technical solution, the compressor is connected in sequence to the first heat exchanger, the third heat exchanger, the fourth heat exchanger and the second heat exchanger.

[0015] The water-cooled solution-based temperature-regulating air conditioning unit of this utility model has the following advantages compared with the prior art:

[0016] 1. This water-cooled solution-based temperature-regulating air conditioning unit employs an intelligent water level control system. The system pre-fills the water storage tank with an appropriate amount of water, and then uses high-precision level sensors to monitor internal water level changes in real time. When the water level drops to a preset warning height, the level sensors immediately feed the information back to the central control system. The system then issues a command to de-energize the electromagnet, causing the float tank to fall smoothly under gravity. At this time, water from the storage tank flows smoothly into the solution tank through the replenishment pipe, accurately replenishing the solution tank to the preset height range. This effectively avoids the problem of excessively high solution concentration due to low water levels, ensuring the stability of system operation.

[0017] 2. This water-cooled solution-based temperature-regulating air conditioning unit employs a dual heat exchange system design. A third heat exchanger is installed at the bottom of the first water tank, and a fourth heat exchanger is installed at the bottom of the second water tank, forming a complete temperature regulation system. The first heat exchanger heats the water in the first water tank to a preset temperature, while the second heat exchanger cools the water in the second water tank to a suitable temperature. Through precise temperature control, the water temperature in the first water tank is kept highly consistent with the temperature of the solution in the first solution tank, and the water temperature in the second water tank is matched with the temperature of the solution in the second solution tank. This design effectively avoids changes in lithium chloride solubility caused by water temperature fluctuations, ensuring the stability of the solution concentration and thus improving the system's temperature regulation efficiency.

[0018] 3. This water-cooled solution-based temperature-regulating air conditioning unit is equipped with multiple safety protection devices. When the water level rises to the set position, the level sensor immediately detects the change, and the control system energizes the electromagnet. As the level float gradually moves to the bottom of the casing, the electromagnet and magnet generate a strong attraction force, completely sealing and blocking the water supply pipe, thus cutting off the water supply channel. This dual protection mechanism not only prevents the solution concentration from becoming too low due to excessive water replenishment, ensuring that the solution always maintains optimal moisture absorption and regeneration performance, but also effectively avoids equipment damage and potential safety hazards caused by solution overflow, greatly improving the system's safety and reliability.

[0024] The following are specific implementation cases and appendices. Figures 1-4 This utility model provides a further description, but it is not limited to these embodiments. This utility model provides a technical solution: a water-cooled solution-based temperature-regulating air conditioning unit, comprising: a casing 1, the front of which is designed as an openable structure with a hinged door for easy operation, allowing for full opening for internal maintenance. The interior of the casing 1 is precision-machined, featuring a large-volume central cavity 2 that extends through the entire casing body. At the bottom inner edge of the casing 1, a first solution tank 8 and a second solution tank 9 are symmetrically arranged, with identical specifications and arranged parallel to each other. A water storage tank 3 is fixedly installed at the center of the bottom inner edge of the central cavity 2. The water storage tank 3 is filled with water through an external inlet pipe and is stably supported by four evenly distributed support columns. The height of the support columns can be adjusted as needed to raise the water storage tank 3. The bottom of the water storage tank 3 is designed as a diversion structure, connecting to two independent water tank units: a first replenishment tank 4 and a second replenishment tank 5. The first water supply tank 4 is connected to the first solution tank 8 via the first water supply pipe 6, and the second water supply tank 5 is connected to the second solution tank 9 via the second water supply pipe 7. A first liquid level float 14 is slidably connected to the inner wall of the first solution tank 8; similarly, a second liquid level float 15 is slidably connected to the inner wall of the second solution tank 9. Both floats are made of lightweight buoyancy material. The main function of the first liquid level float 14 is to automatically rise and block the first water supply pipe 6 from continuing to supply water when the liquid level in the first solution tank 8 reaches a preset height, preventing excessive water supply. The second liquid level float 15 performs the same function; when the liquid level in the second solution tank 9 reaches a set value, it will promptly block the water supply channel of the second water supply pipe 7, ensuring that the liquid levels in both solution tanks are always kept within a safe range.

[0025] As a preferred embodiment, the bottom of the first water supply pipe 6 is further fixedly installed with a first base shell 10 via a flange connection. The first base shell 10 is made of 304 stainless steel, has a square structure, and extends downwards into the interior space of the first solution tank 8. Similarly, the bottom of the second water supply pipe 7 is also installed with a second base shell 11 using the same connection method. The second base shell 11 is also made of corrosion-resistant 304 stainless steel, and its structural design is similar to that of the first base shell 10, extending downwards through the interior cavity of the second solution tank 9. The extended portions of both base shells maintain an appropriate distance from the inner wall of the solution tank to ensure smooth solution flow.

[0026] As a preferred embodiment, a first sliding rod 12 is vertically installed on the inner wall of the first solution tank 8. This first sliding rod 12 is arranged vertically to ensure it remains perpendicular to the horizontal plane (90 degrees). The corresponding first liquid level float 14 is smoothly connected to the first sliding rod 12 via a precision-machined sliding mechanism. Similarly, a second sliding rod 13 is also vertically fixed to the inner wall of the second solution tank 9. This second sliding rod 13 is also strictly vertically installed. The corresponding second liquid level float 15 is connected to the second sliding rod 13 via a sliding connection mechanism of the same specifications, forming a stable sliding fit. Both sliding rod systems are made of high-quality stainless steel to ensure that they will not corrode or deform during long-term use in a solution environment, thus guaranteeing the accuracy and reliability of liquid level monitoring.

[0027] As a preferred embodiment, the first liquid level float 14 is further composed of several key components, including a first float 141, a first arc-shaped component 142, a first magnet 143, and a first sleeve block 144. The first float 141 serves as the main structure, with the first arc-shaped component 142 fixedly mounted at its top center. This arc-shaped component is specially designed to perfectly fit the opening of the first bottom shell 10. First magnets 143 are symmetrically mounted at the four corners of the top of the first float 141, arranged in a rectangular array. Furthermore, a first sleeve block 144 is provided on one outer wall of the first float 141. This sleeve block has internal grooves that allow for sliding engagement with the first sliding rod 12, ensuring stable and reliable vertical movement of the float. The main function of the first arc-shaped component 142 is to completely seal the opening of the first bottom shell 10 when the float rises, creating a sealed state. Correspondingly, electromagnet devices are precisely installed at the four corners of the bottom of the first bottom shell 10. These electromagnets are energized and de-energized via a power control system. Of particular note is that each first magnet 143 is precisely aligned vertically with its corresponding electromagnet. A high-precision first liquid level sensor 16 is also installed on the inner wall of the first solution tank 8. This sensor can monitor changes in the liquid level in the tank in real time. When the first liquid level sensor 16 detects that the water level in the solution tank is below a preset safety threshold, the control system immediately cuts off the power supply to the electromagnet, causing it to lose its magnetism and thus releasing the attraction force on the first magnet 143, resulting in the first liquid level float 14 descending smoothly under gravity.

[0028] As a preferred embodiment, the second liquid level float 15 is further composed of several key components, including a second float 151, a second arc-shaped component 152, a second magnet 153, and a second sleeve block 154. The second float 151 serves as the main structure, with the second arc-shaped component 152 fixedly mounted at its top center. This arc-shaped component is precisely designed to perfectly fit the opening of the second bottom shell 11. At each of the four corners of the top of the second float 151, a second magnet 153 is installed, symmetrically distributed to ensure uniform force distribution. Furthermore, a second sleeve block 154, made of wear-resistant material, is provided on one side of the second float 151, allowing it to slide smoothly on the second slide rod 13. The main function of the second arc-shaped component 152 is to effectively seal the opening of the second bottom shell 11 when the float rises, preventing liquid leakage. It is worth noting that electromagnets are also installed at the four corners of the bottom of the second bottom shell 11. These electromagnets are powered by a dedicated power supply line and control circuit, and their positions correspond perfectly with the second magnet 153 in the vertical direction, ensuring the accuracy of the magnetic force. A high-precision second liquid level sensor 17 is installed on the inner wall of the second solution tank 9. This sensor can monitor changes in the liquid level in the tank in real time. When the second liquid level sensor 17 detects that the liquid level in the solution tank is lower than the preset safety warning line, the control system will immediately activate the protection mechanism, cutting off the power supply circuit of the electromagnet and causing it to lose its magnetism. This operation will immediately release the electromagnet from the magnetic attraction of the second magnet 153. Under the action of gravity, the entire second liquid level float 15 will sink smoothly and slowly along the second slide bar 13, ensuring the safety and reliability of the system operation.

[0029] As a preferred embodiment, the first solution tank 8 and the second solution tank 9 are further interconnected via a permeable membrane 18. This permeable membrane 18 is made of a selectively permeable material with specific pore size and permeation characteristics. During operation, the main function of the permeable membrane 18 is to allow water molecules in the second solution tank 9 to permeate unidirectionally into the first solution tank 8 under the influence of osmotic pressure difference, while effectively blocking the passage of other solute molecules. This design achieves controllable water transfer between the two solution tanks, ensuring that the first solution tank 8 can continuously receive water replenishment from the second solution tank 9, while maintaining a relatively stable solution concentration in both tanks. The selective permeation characteristics of the permeable membrane 18 are key to the directional water transfer achieved by this system.

[0030] As a preferred option, the top area of ​​the chassis 1 is meticulously designed with four functional ventilation interfaces: a fresh air outlet 22 for discharging treated fresh air, a dehumidifier fan connection port 23 specifically for connecting to dehumidification equipment, an exhaust vent 24 for discharging internal recirculated air, and a regenerator fan connection port 25 for connecting to the air regeneration system. Within the internal structure of the chassis 1, four airflow channels are carefully arranged: the first exhaust chamber 26 is located directly below the fresh air outlet 22, forming a vertical airflow path; the first intake chamber 27 is located at the bottom of the dehumidifier fan connection port 23, ensuring smooth passage of dehumidifying airflow; the first exhaust chamber 26 communicates with the first intake chamber 27; the second exhaust chamber 31 corresponds vertically to the top exhaust vent 24, forming a complete exhaust system; and the second intake chamber 32 is located directly below the regenerator fan connection port 25, providing a dedicated channel for regeneration airflow. Of particular note is that the opening position of the first solution tank 8 has been precisely calculated and is located directly below the second exhaust chamber 31, forming a corresponding structural relationship between the upper and lower parts. The second exhaust chamber 31 and the second air inlet chamber 32 are connected. Similarly, the opening of the second solution tank 9 has also been carefully designed and is located directly below the first exhaust chamber 26 to ensure that the airflow and liquid processing of the entire system can operate in a coordinated manner.

[0031] As a preferred option, further in the structural design of the air handling system, the first exhaust chamber 26 serves as the main channel for air exhaust, and a first packed tower 28 is carefully installed inside to ensure sufficient contact and reaction between air and solution. Simultaneously, the first inlet chamber 27 serves as the inlet channel for fresh air, and a first heat exchanger 29 is installed inside to regulate the temperature of the air entering the system. On the other side of the system, the second exhaust chamber 31 also serves as a waste gas exhaust channel, and a second packed tower 33 is installed inside, with a structure similar to the first packed tower 28 but operating independently. Correspondingly, the second inlet chamber 32 houses a second heat exchanger 34, forming a symmetrical arrangement with the first heat exchanger 29 to jointly ensure the uniformity of system temperature control. This symmetrical design not only improves the system's processing efficiency but also enhances the stability and reliability of the equipment.

[0032] As a preferred embodiment, two key solution delivery devices are symmetrically installed in the bottom area of ​​the central cavity 2: a first solution pump 19 and a second solution pump 20. The first solution pump 19 is connected to the first solution tank 8 via a piping system and is specifically responsible for drawing the required solution from the first solution tank 8; while the second solution pump 20 is connected to the second solution tank 9 and its main function is to draw a specific solution from the second solution tank 9. In the upper structure of the equipment, the top of the first packed tower 28 is equipped with a first water spray pipe 30, which is used to evenly distribute the liquid; similarly, the top of the second packed tower 33 is also equipped with a corresponding second water spray pipe 35 to ensure that the liquid can be sprayed evenly. It is worth noting that the output piping system of the second solution pump 20 adopts a special design, first undergoing heat exchange through the first heat exchanger 29 before connecting to the first water spray pipe 30; while the output piping of the first solution pump 19 first undergoes temperature regulation through the second heat exchanger 34, ultimately forming a complete liquid delivery loop with the second water spray pipe 35. This cross-connected piping design enables heat exchange and recycling of the two solution systems.

[0033] As a preferred embodiment, a compressor 21 is fixedly installed at the top of the water storage tank 3. This compressor is the core component of the entire system. A third heat exchanger 401 is located at the bottom of the first water supply tank 4. The installation position of this heat exchanger is carefully designed to completely surround the outside of the first water supply pipe 6, ensuring sufficient heat exchange. Similarly, a fourth heat exchanger 501 is installed at the bottom of the second water supply tank 5. This heat exchanger also adopts a surrounding design, tightly wrapping around the outside of the second water supply pipe 7. The water storage tank 3 and the first water supply tank 4 are connected through a first drain pipe 301, while the water storage tank 3 and the second water supply tank 5 are connected through a second drain pipe 302. The heat exchange network of the entire system is driven by the compressor 21, sequentially connecting the first heat exchanger 29, the third heat exchanger 401, the fourth heat exchanger 501, and the second heat exchanger 34, forming a complete thermodynamic circulation loop. In this cycle, compressor 21 first heats the first heat exchanger 29 and the third heat exchanger 401 to raise their temperature. The air, after being processed by the third heat exchanger 401, flows through a cooler and then enters the fourth heat exchanger 501 for further processing. This design allows the fourth heat exchanger 501 and the second heat exchanger 34 to effectively cool down, ultimately achieving a high degree of matching between the makeup water temperature and the internal temperature of the solution tank, thus completely avoiding various problems that may arise from excessive temperature differences.

[0034] The solution tank, level sensor, permeable membrane, solution pump, compressor, heat exchanger, and magnet in this case are existing technologies. Any solution tank, level sensor, permeable membrane, solution pump, compressor, heat exchanger, and magnet that meet the requirements of this case are acceptable.

[0035] The specific types or circuit structures of the controllers for the electrical components mentioned in this application, as well as the circuit connection relationships between the electrical components and the accurate coordinated control of multiple power components, are all prior art. Therefore, the above content will not be elaborated upon in this application.

[0036] Working Principle: All electrical components described in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions before use. Before use, system preparation is required. First, completely fill the water storage tank 3 with clean water to ensure sufficient water volume. Then, fill the first water replenishment tank 4 through the first drain pipe 301, and simultaneously fill the second water replenishment tank 5 through the second drain pipe 302. After preparation, activate the electromagnet device installed at the bottom of the first base shell 10. This electromagnet generates a strong magnetic force, firmly attracting the first magnet 143. This causes the first liquid level float 14 to adhere tightly to the bottom of the first base shell 10, while the first arc-shaped component 142 is precisely inserted into the opening at the bottom of the first base shell 10, forming a seal. The same operation applies to the second bottom shell 11. After the electromagnet at its bottom is activated, the electromagnet will attract the second magnet 153, causing the second liquid level float 15 to be tightly attached to the bottom of the second bottom shell 11. The second arc-shaped piece 152 will also be inserted into the opening at the bottom of the second bottom shell 11, thereby effectively preventing water from leaking out.

[0037] When the system is in operation, compressor 21 is started first. After compressor 21 starts running, it simultaneously heats the second heat exchanger 34 and the third heat exchanger 401. The high-temperature gas generated by heating is cooled by the refrigerator and then discharged into the first heat exchanger 29 and the fourth heat exchanger 501, respectively. At the same time, the dehumidifier draws the high-temperature and high-humidity outdoor air into the first air inlet chamber 27 and the first air outlet chamber 26. The second solution pump 20 pumps the lithium chloride solution stored in the second solution tank 9 into the first heat exchanger 29. After cooling, the solution is sent to the first water spray pipe 30 to spray the first packed tower 28 evenly. This process achieves a second solution shower purification of the air, which can effectively kill viruses, bacteria and other harmful microorganisms in the air. The solution after being cooled and dehumidified by compressor 21 can not only reduce the air temperature, but also absorb gaseous water molecules in the air, and finally discharge the low-temperature dry fresh air out of the system. On the other hand, the regenerator sends the dry air into the second air inlet chamber 32 and the second air outlet chamber 31. The first solution pump 19 pumps the lithium chloride solution from the first solution tank 8 into the second heat exchanger 34. After being heated, the solution is sent to the second spray pipe 35 to spray the second packed tower 33. This solution shower process achieves heat recovery and also kills viruses and bacteria in the air. After being heated by the compressor 21, the second heat exchanger 34 heats the solution to about 45 degrees Celsius, achieving the separation and release of gaseous water molecules in the solution within the second packed tower 33.

[0038] As the system continues to operate, the low-concentration solution in the second solution tank 9 will permeate water molecules into the first solution tank 8 through the permeation membrane 18, causing the water levels in both tanks to gradually decrease. When the water level drops to the monitoring position of the first liquid level sensor 16 and the second liquid level sensor 17, these two sensors will feed back the water level information to the electromagnet control system in real time. Upon receiving the signal, the control system will immediately cut off the power to the electromagnet, causing the first liquid level float 14 and the second liquid level float 15 to slide down the liquid surface under the action of gravity. At this time, the water heated by the third heat exchanger 401 in the first water replenishment tank 4 will automatically flow into the first solution tank 8, while the water cooled by the fourth heat exchanger 501 in the second water replenishment tank 5 will also flow into the second solution tank 9, achieving rapid water replenishment and effectively preventing the stability decrease caused by the increase in solution concentration. As the water replenishment process proceeds, the water level will gradually rise, and when the water level reaches the set height, the electromagnet will be energized again. When the first magnet 143 and the second magnet 153 re-fit tightly with the electromagnets on both sides, the bottom openings of the first bottom shell 10 and the second bottom shell 11 will be re-sealed, the water replenishment process will stop, and the system will return to normal operation.
