Description

Technical Field

[0001] This utility model relates to an air conditioning device, specifically an air conditioning device that automatically controls temperature and humidity using the principle of water vaporization refrigeration, belonging to the fields of energy-saving technology and HVAC technology. Background Technology

[0002] Besides providing comfort to people, air conditioning is also used in industrial and agricultural applications to achieve appropriate temperature and humidity levels to suit production conditions. For example, in dry seasons, some factory workshops need humidification to prevent static electricity; large-scale farms require cooling and fresh air exchange in summer; and in edible mushroom cultivation, air temperature and humidity significantly impact growth, often requiring artificial control in seasons or regions with unfavorable climates. In these scenarios, traditional compressor-based air conditioners lack humidification capabilities, necessitating the addition of humidifiers, which incurs high equipment investment and energy costs. Traditional water curtain air conditioners offer poor cooling and uncontrollable humidification. For situations requiring long-term air conditioning to maintain optimal temperature and humidity, traditional air conditioning equipment alone is insufficient.

[0003] Chinese patent application "Air Conditioning Device Utilizing Water Vaporization Refrigeration" (2024115105847) employs molecular sieve honeycomb technology for water vaporization refrigeration. This technology eliminates the need for a compressor, with the entire device's power consumption primarily coming from the fan, resulting in good energy savings. However, for long-term, high-volume operation, there are still shortcomings in fan energy efficiency. This is mainly because the device's internal air ducts have many bends, increasing airflow resistance and requiring a fan with slightly higher air pressure. The increased air pressure necessitates a corresponding increase in fan power. If the air conditioner operates at 50,000 m³ / h for extended periods... 3 When the air volume is above / h, the electricity cost consumed by the fan is a considerable expense.

[0004] Furthermore, the above technologies do not take temperature and humidity control into account, which is an important function of air conditioning units. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a water vaporization refrigeration air conditioning device with automatic temperature and humidity control. This air conditioning device has the functions of large air volume and automatic temperature and humidity control.

[0006] The present invention can adopt the following technical solution:

[0007] A water vaporization refrigeration air conditioning device with automatic temperature and humidity control includes a housing, a fan, a honeycomb structure, a sprayer, and a temperature and humidity control device. The fan is located at the air inlet or air outlet of the housing. The honeycomb structure consists of multiple square honeycomb units vertically assembled and located between the air inlet and air outlet within the housing. The airflow from the air inlet to the air outlet needs to pass through the honeycomb channels of the honeycomb structure. The sprayer is located in front of the air inlet surface of the honeycomb structure, and the water mist sprayed by the sprayer can reach the air inlet surface of all the honeycomb structures. The temperature and humidity control device has an electrically connected sensor located at the air outlet. The output terminal of the temperature and humidity control device is electrically connected to the control switch of the water supply device of the sprayer.

[0008] The following improvements can be further implemented to solve the problem of this utility model:

[0009] Further improvements include: the honeycomb unit is sintered from zeolite molecular sieve material, carbon molecular sieve material, or microporous ceramic material.

[0010] Further improvements include: the honeycomb units are mounted on a support and stacked to form a wall-like structure, with a seal between the honeycomb units and the inner wall of the shell.

[0011] Further improvements include: the sprayer is connected to a water supply device; the water supply device for the sprayer is a water pump, and the control switch for the water supply device is the control switch for the water pump; or the water supply device for the sprayer is a tap water pipe, and the control switch for the water supply device is the switch of a solenoid valve on the tap water pipe.

[0012] Further improvements were made by using a temperature sensor.

[0013] Further improvements were made by using a temperature and humidity sensor.

[0014] A further improvement is that the sprayer can be one or more.

[0015] Further improvements include: the fan is located at the air inlet or air outlet of the casing, and the number of fans can be one or more.

[0016] Further improvements were made as follows: the air inlet is located directly in front of the air inlet surface of the honeycomb structure, and the air inlet is straight through; the air outlet is located directly in front of the air outlet surface of the honeycomb structure, and the air outlet is also straight through; the internal air passage has no bends, and the air enters and exits straight through under the drive of the fan.

[0017] The above technical solution has the following technical effects:

[0018] 1. This utility model adopts a vertically combined honeycomb structure, which is suitable for placing this utility model on the side of a building against the wall. It can install more honeycomb cells without occupying a large floor area and ensure a sufficiently large air passage area. The air inlet can directly draw in fresh outdoor air, which is suitable for the design of a fresh air air conditioner with ultra-large air volume.

[0019] 2. This utility model uses a temperature and humidity control device to control the amount of water sprayed by the sprayer, thereby realizing automatic control of the air temperature and humidity of the air conditioner.

[0020] 3. The internal air passage of this utility model has no bends, and the air enters and exits straight under the drive of the fan, which greatly reduces the air passage resistance. A large-volume, low-pressure, and low-energy-consumption axial flow fan can be used to achieve energy saving while ensuring sufficient air volume.

[0021] 4. Compared with water curtain air conditioners, the honeycomb molecular sieve material used in this utility model for heat exchange and refrigeration has a stronger capillary moisture diffusion capacity than the honeycomb paper used in water curtain air conditioners. It also has a huge specific surface area, which increases the contact area between water and air, and can greatly improve the rate of water evaporation. The transfer of a large amount of latent heat of water evaporation can greatly increase the refrigeration efficiency and humidification capacity.

[0022] 5. This utility model adopts a spray method, and the water mist can be dispersed by the wind. It is more uniform in wetting the honeycomb body than the traditional spraying method, and also greatly reduces the excess water flowing down from the spray. Compared with the technical solution of using tap water to directly supply water to the sprayer, it can significantly reduce the amount of excess water discharged to save water resources.

[0023] 6. The refrigeration process of this utility model does not require the compressor to work, thus saving energy. It does not use chemical refrigerants, which reduces environmental pollution.

[0024] 7. The sprayer of this utility model is equipped with an automatic water spray volume control device, which can control the moisture content of the honeycomb used for vaporization refrigeration and humidification to always keep it within a reasonable range. It can select a refrigeration working mode that prioritizes the control of the outlet air temperature or a humidification working mode that prioritizes the control of the outlet air relative humidity. It can also implement simultaneous temperature and humidity control within a certain working range, ensuring the continuous and stable operation of the entire refrigeration or humidification process.

[0025] 8. This utility model has a simple structure and the advantages of high reliability and long service life. Attached Figure Description

[0030] The present invention will now be described in detail with reference to specific embodiments.

[0031] Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, a water vaporization refrigeration air conditioning device with automatic temperature and humidity control includes a housing 1, a fan 8, a honeycomb structure 2 with combined structure, a sprayer 4, and a temperature and humidity control device 11. The fan 8 is located at the air inlet end 5 of the housing 1. The honeycomb structure 2 consists of multiple square honeycomb units vertically combined and located between the air inlet end 5 and the air outlet end 6 inside the housing 1. The airflow from the air inlet end 5 to the air outlet end 6 needs to flow through the honeycomb channels of all the honeycomb cells 2. The honeycomb cells 2 have good water absorption and a large specific surface area. The sprayer 4 is located in front of the air inlet surface of the honeycomb cells 2, and the water mist sprayed by the sprayer 4 can reach the air inlet surface of all the honeycomb cells 2. The temperature and humidity control device 11 is electrically connected to a sensor 12 located at the air outlet end 6. The output end of the temperature and humidity control device 11 is electrically connected to the control switch of the water supply device of the sprayer 4.

[0032] In this example: the honeycomb cell 2 unit is made of zeolite molecular sieve material by sintering, which has a well-developed pore structure and a huge specific surface area, and has good water absorption and weather resistance.

[0033] In this example: the honeycomb 2 unit is installed on the bracket 3 and stacked to form a wall-like structure, and the honeycomb 2 of the combined structure is sealed with the inner wall of the shell 1.

[0034] In this example: the sprayer 4 is connected to a water supply device, the water supply device of the sprayer 4 is a water pump, and the control switch of the water supply device of the sprayer 4 is the control switch of the water pump; or the water supply device of the sprayer 4 is a tap water pipe, and the control switch of the water supply device of the sprayer 4 is the switch of the solenoid valve on the tap water pipe.

[0035] In this example: the temperature and humidity control device 11 is connected to a temperature sensor 12, which controls the amount of water sprayed by the sprayer by obtaining the temperature data, so as to realize a cooling working mode that prioritizes the control of the outlet air temperature.

[0036] In this example: there are multiple sprayers 4.

[0037] In this example: The honeycomb body 2 is provided with a connecting pipe 10 below which connects the bottom of the air inlet end 5 and the air outlet end 6 to each other, and a drain outlet 9 is provided at the bottom of the air outlet end 5. The drain outlet 9 can drain away the water accumulated at the bottom of the air inlet end 5 and the air outlet end 6 together.

[0038] In this example: the fan 8 is located at the air inlet end 5 of the housing 1, and there are multiple fans.

[0039] This example uses an axial flow fan located at the air inlet. Installing the fan near the outside reduces indoor noise, and the heat generated by the fan motor also enters the honeycomb structure for cooling, resulting in a lower indoor temperature.

[0040] In this example: the air inlet is located directly in front of the air inlet surface of the honeycomb body 2, and the air inlet is straight. The air outlet is located directly in front of the air outlet surface of the honeycomb body 2, and the air outlet is also straight. The internal air passage has no bends, and the air enters and exits straight under the drive of the fan.

[0041] Working principle: such as Figure 1-3 As shown, the working process of this utility model is as follows: The fan and sprayer are started. The sprayer sprays water mist onto the air inlet surface of the honeycomb structure. Because the spray direction is consistent with the airflow direction, the water mist enters the front honeycomb channels of the honeycomb structure with the help of the wind and is absorbed. Excess or splashed water flows down to the bottom of the honeycomb structure and is finally discharged through the drain outlet. Driven by the fan, external air enters from the air inlet end, passes through the honeycomb channels of the honeycomb structure, and is discharged, completing the cooling of the flowing air. Throughout the process, the moisture content of the honeycomb structure is controlled by a temperature and humidity control device to ensure the continuous stability of the entire cooling process.

[0042] The working principle of each stage in the refrigeration process of Embodiment 1 of this utility model:

[0043] In the first stage, the sprayer is activated when the temperature at the air outlet reaches the upper limit. The water mist comes into contact with the air inlet surface of the honeycomb structure with the wind. The water is absorbed by the pore wall at the front of the honeycomb channel. During this process, the water does not undergo a phase change and remains in a liquid state. As the airflow continues to move forward, the water carried by it is gradually absorbed by the honeycomb channel wall and becomes less and less. In this stage, the water vaporization rate is low and the latent heat effect has a small cooling effect on the airflow. The main function of this stage is for the airflow to transfer the liquid water it carries to the front honeycomb channel wall of the honeycomb structure and be absorbed by it.

[0044] In the second stage, the water absorbed by the front honeycomb channel wall is diffused through the capillary action formed by the well-developed microchannels inside the molecular sieve material. The purpose of this stage is to allow the water inside the honeycomb to diffuse in the direction of air outlet.

[0045] The third stage: After the water in the honeycomb diffuses to the rear honeycomb channel wall, it comes into contact with the airflow again. Due to the huge specific surface area of ​​the zeolite material, coupled with the negative pressure generated by the gas flow in the honeycomb channel, the water in the honeycomb channel wall will quickly vaporize. The latent heat generated by the water vaporization phase change will cool down the honeycomb channel wall. The role of this stage is to cool the rear honeycomb channel wall by water vaporization.

[0046] Fourth stage: After the incoming airflow transfers the water mist at the front of the honeycomb channel, it exchanges heat with the cooled honeycomb channel wall as it passes through the rear of the honeycomb channel. This stage completes the cooling of the airflow.

[0047] Fifth stage: When the temperature at the air outlet reaches the lower limit and the sprayer is turned off, a considerable amount of moisture is still retained in the honeycomb for a considerable period of time. During this stage, the entire or part of the honeycomb channel can maintain the cooling function of efficient water vaporization until the temperature reaches the upper limit (i.e., the moisture in the honeycomb is reduced to the trough), at which point the next round of spraying is started and the cycle continues.

[0048] Too much or too little water sprayed onto the honeycomb structure by the sprayer will affect the cooling effect. If the water spray is too little, insufficient water evaporation will reduce the cooling capacity. However, the water spray should not be too much either. On the one hand, excessive water spray will waste water resources, and on the other hand, liquid water may even clog the honeycomb channels. Furthermore, once the zeolite material is saturated with water, its surface will be covered by a water film formed by the surface tension of the water, reducing the efficient vaporization effect brought about by the large specific surface area of ​​the zeolite material. Therefore, during the cooling operation, the honeycomb structure should neither be too dry nor too saturated with water. This problem is solved by the temperature and humidity control device 11, which measures the temperature at the air outlet 6 using the sensor 12. During operation, the moisture content of the honeycomb cells is negatively correlated with the temperature at the air outlet. When the outlet temperature is low, the corresponding moisture content of the honeycomb cells is high, and the water vaporization rate reaches a high level, resulting in better cooling efficiency. When the outlet temperature exceeds the set limit, it indicates insufficient moisture content in the honeycomb cells, requiring the sprayer to be activated for humidification. Therefore, the temperature and humidity control device controls the start and stop of the sprayer's water supply based on the upper and lower limits set for the outlet temperature, ensuring the moisture content of the honeycomb cells remains within a reasonable range for optimal cooling. The spray volume can be controlled by adjusting the flow rate of the water supply throttle valve or by using intermittent spraying. This intermittent spraying maintains the moisture content of the honeycomb cells within a certain range, ensuring good conditions for water vaporization as long as a reasonable proportion of moisture remains within the cells. The cooling and humidification processes will not be affected when spraying stops.

[0049] Example 2: Figure 1 and Figure 4As shown, a water vaporization refrigeration air conditioning device with automatic temperature and humidity control includes a housing 1, a fan 8, a honeycomb structure 2 with combined structure, a sprayer 4, and a temperature and humidity control device 11. The fan 8 is located at the air outlet 6 of the housing 1. The honeycomb structure 2 consists of multiple square honeycomb cells 2 combined and located between the air inlet 5 and the air outlet 6 inside the housing 1. The airflow from the air inlet 5 to the air outlet 6 needs to flow through the honeycomb channels of all the honeycomb cells 2. The honeycomb cells 2 have good water absorption and a large specific surface area. The sprayer 4 is located in front of the air inlet surface of the honeycomb cells 2, and the water mist sprayed by the sprayer 4 can reach the air inlet surface of all the honeycomb cells 2. The temperature and humidity control device 11 is electrically connected to a sensor 12 located at the air outlet 6. The output terminal of the temperature and humidity control device 11 is electrically connected to the control switch of the water supply device of the sprayer 4.

[0050] In this example: the honeycomb 2 is made of microporous ceramic material by sintering, which has a well-developed pore structure and a huge specific surface area, and has good water absorption and weather resistance;

[0051] In this example: the honeycomb 2 unit is installed on the bracket 3 and stacked to form a wall-like structure, and the honeycomb 2 of the combined structure is sealed with the inner wall of the shell 1.

[0052] In this example: the sprayer 4 is connected to a water supply device, the water supply device of the sprayer 4 is a water pump, and the control switch of the water supply device of the sprayer 4 is the control switch of the water pump; or the water supply device of the sprayer 4 is a tap water pipe, and the control switch of the water supply device of the sprayer 4 is the switch of the solenoid valve on the tap water pipe.

[0053] In this example: the temperature and humidity control device 11 is connected to a temperature and humidity sensor 12, which controls the amount of water sprayed by the sprayer by obtaining relative humidity data, so as to realize a humidification working mode that prioritizes the control of the relative humidity of the air outlet.

[0054] In this example: there are multiple sprayers 4.

[0055] In this example: The honeycomb body 2 is provided with a connecting pipe 10 below which connects the bottom of the air inlet end 5 and the air outlet end 6 to each other, and a drain outlet 9 is provided at the bottom of the air outlet end 5. The drain outlet 9 can drain away the water accumulated at the bottom of the air inlet end 5 and the air outlet end 6 together.

[0056] The difference between this example and Example 1 is that the fan 8 is located at the air outlet 6 of the housing 1, and there is only one fan. An axial flow fan located at the air outlet is used for exhaust. Negative pressure exhaust can further reduce the turbulence of airflow in the duct and reduce the duct resistance. Under the same fan power, negative pressure exhaust can obtain a larger air volume and a longer air outlet range than positive pressure exhaust.

[0057] Another difference between this example and Example 1 is that the temperature and humidity control device 11 is connected to a temperature and humidity sensor 12, which can obtain the relative humidity value at the air outlet, thus facilitating direct control of the relative humidity of the air outlet. Since the relative humidity value at the air outlet is positively correlated with the moisture content of the honeycomb structure, this example controls the amount of water sprayed by the sprayer to maintain the moisture content of the honeycomb structure within a certain range, thereby controlling the relative humidity of the air outlet. Of course, in Example 2, the dry-bulb temperature value from the temperature and humidity sensor can be selected for control, easily switching from the humidification mode (prioritizing relative humidity control) of Example 2 to the cooling mode (prioritizing temperature control) of Example 1.

[0058] The working principle of each stage of the humidification process in Example 2 is basically the same as that in Example 1. However, in Example 1, the spray volume of the sprayer is controlled by the temperature value at the air outlet to control the air outlet temperature within a certain range, while in Example 2, the spray volume of the sprayer is controlled by the relative humidity value at the air outlet to control the relative humidity of the air outlet within a certain range.

[0059] This invention simultaneously cools during the humidification process, achieving simultaneous cooling and humidification. Depending on actual needs, a control mode prioritizing either the outlet air temperature or the outlet relative humidity can be selected, or a set value within the intersection of the two values ​​can be selected to achieve simultaneous automatic control of temperature and humidity.

[0060] Analysis of the external structure and material properties of the honeycomb structure in the two embodiments above shows that the honeycomb structure has a large air-expanding area. The materials used in the honeycomb structure have extremely high specific surface area and dense, open pores inside. The dense capillaries formed from the inside out play an extremely important role in realizing the functions of rapid absorption, rapid transfer and diffusion, and rapid evaporation of moisture.

[0061] This invention differs from traditional water curtain air conditioners in its structure, as well as its cooling or humidifying working principle and process. It is difficult for traditional water curtain air conditioners to match its cooling and humidifying performance.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
