Description

Technical Field

[0001] The present invention relates to an air conditioning device, in particular to an air conditioning device which automatically controls temperature and humidity by using the principle of full water vaporization refrigeration, and belongs to the field of energy-saving technology and HVAC technology. Background Art

[0002] In addition to making people feel comfortable, air conditioning also needs to be used in industry or agriculture to obtain the corresponding temperature and humidity to adapt to production conditions. For example, in dry seasons, some factory workshops need to humidify the air to prevent the generation of static electricity. Large-scale farms also need to implement cooling and fresh air ventilation in summer. In the cultivation of edible fungi, air temperature and humidity have a great impact on the growth of edible fungi. In seasons or regions with poor climatic conditions, temperature and humidity often need to be controlled by artificial means. In the above scenarios, traditional compressor refrigeration air conditioners need to add humidifiers to assist because they do not have a humidification function. This requires high equipment investment costs and operating energy consumption costs, while traditional water curtain air conditioners have poor cooling effects and uncontrollable humidification. In the case where air conditioners are needed to ensure the quality of air temperature and humidity for a long time, it is difficult to use traditional air conditioning equipment alone.

[0003] The Chinese patent application "Air conditioning device using full water vaporization refrigeration" (2024115105847) adopts the technology of water vaporization refrigeration by molecular sieve honeycomb. This technology does not need to use compressor refrigeration. The power consumption of the entire device basically comes from the fan, which has a good energy-saving effect. However, it is still insufficient in fan energy saving when long-term large air volume operation is required. The main reason is that the internal air duct of the device of this technology has many bends, which increases the air duct resistance. A fan with slightly higher wind pressure needs to be used. The increase in wind pressure causes the fan operating power to increase accordingly. If the air conditioner is operated at 50,000m for a long time, 3 When the air volume is above 400 / h, the electricity consumed by the fan is a considerable expense.

[0004] Furthermore, the above technology does not take temperature and humidity control into consideration, which is an important function in an air conditioning device. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a water vaporization refrigeration air-conditioning device with automatic temperature and humidity control, which has the functions of large air volume and automatic temperature and humidity control.

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

[0007] A water vaporization refrigeration and air conditioning device with automatic temperature and humidity control comprises a shell, a fan, a honeycomb body of a combined structure, a sprayer and a temperature and humidity control device; the fan is arranged at the air inlet end or the air outlet end of the shell; the honeycomb body is a plurality of square honeycomb body units which are vertically assembled and arranged between the air inlet end and the air outlet end in the shell, and the airflow from the air inlet end to the air outlet end needs to flow through the honeycomb pores of the honeycomb body; the sprayer is arranged in front of the air inlet surface of the honeycomb body, and the water mist sprayed by the sprayer can reach the air inlet surface of all honeycomb bodies; the sensor electrically connected to the temperature and humidity control device is arranged at the air outlet end; the output end of the temperature and humidity control device is electrically connected to the control switch of the water supply device of the sprayer.

[0008] The present invention can further adopt the following improvement measures to solve the problem:

[0009] The further improvement measure is: the honeycomb unit is made by sintering zeolite molecular sieve material or carbon molecular sieve material or microporous ceramic material.

[0010] Further improvement measures are as follows: the honeycomb units are mounted on a bracket and stacked to form a wall-like structure, and the honeycomb is sealed from the inner wall of the shell.

[0011] Further improvement measures are as follows: the sprayer is connected to a water supply device; the water supply device of the sprayer is a water pump, and the control switch of the water supply device of the sprayer is the control switch of the water pump; or the water supply device of the sprayer is a water pipe, and the control switch of the water supply device of the sprayer is the switch of the solenoid valve on the water pipe.

[0012] Further improvement measures taken are: the sensor is a temperature sensor.

[0013] Further improvement measures taken are: the sensor is a temperature and humidity sensor.

[0014] A further improvement measure is as follows: the sprayer can be one or more.

[0015] Further improvement measures are as follows: the fan is arranged at the air inlet end or the air outlet end of the shell, and the number of the fans can be one or more.

[0016] Further improvement measures are as follows: the air inlet is located directly in front of the air inlet surface of the honeycomb body, the air inlet is straight, the air outlet is located directly in front of the air outlet surface of the honeycomb body, the air outlet is also straight, the internal air passage has no bends, and the air goes straight in and out under the drive of the fan.

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

[0018] 1. The present invention adopts a vertically assembled honeycomb structure, which is suitable for being placed on the wall side of a building. More honeycombs can be installed without occupying a large floor area and a sufficiently large wind flow area can be ensured. The air inlet end can directly take in outdoor fresh air, which is suitable for the design of a fresh air air conditioner with a large air volume.

[0019] 2. The present invention adopts a temperature and humidity control device to control the water spraying amount of the sprayer, thereby realizing automatic control of the air outlet temperature and humidity of the air conditioning device.

[0020] 3. The internal wind passage of the present invention has no bends, and the air goes straight in and out under the drive of the fan, which greatly reduces the wind duct resistance. An axial flow fan with large air volume, low air pressure and low energy consumption can be used to achieve energy saving while ensuring sufficient air volume.

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

[0022] 5. The present invention adopts a spraying method, and the water mist can be dispersed by wind power, which makes the honeycomb body more evenly moistened than the traditional spraying method, and also greatly reduces the excess water accumulation from the spraying flow. Compared with the technical solution of using tap water directly to supply water to the sprayer, it can greatly reduce the discharge of excess water to save water resources.

[0023] 6. The refrigeration process of the present invention does not require the compressor to work and thus saves energy. No chemical refrigerant is used and thus the pollution to the environment can be reduced.

[0024] 7. The sprayer of the present invention is equipped with an automatic water spray volume control device, which can control the water content of the honeycomb used for gasification refrigeration and humidification to always remain in a reasonable range. The refrigeration working mode with priority given to the control of the air outlet temperature or the humidification working mode with priority given to the control of the air outlet relative humidity can be selected. The temperature and humidity can also be controlled simultaneously within a certain working range, thereby ensuring the continuous stability of the entire refrigeration or humidification operation.

[0025] 8. The present invention has the advantages of simple structure, high reliability and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is described in detail below with reference to specific embodiments.

[0031] Example 1: Figure 1 , Figure 2 , Figure 3 As shown, a water vaporization refrigeration and air-conditioning device with automatic temperature and humidity control comprises a shell 1, a fan 8, a honeycomb body 2 of a combined structure, a sprayer 4 and a temperature and humidity control device 11; the fan 8 is arranged at the air inlet end 5 of the shell 1; the honeycomb body 2 of the combined structure is a plurality of square honeycomb unit units vertically combined and arranged between the air inlet end 5 and the air outlet end 6 in the shell 1, and the air flow from the air inlet end 5 to the air outlet end 6 needs to flow through the honeycomb pores of all the honeycomb bodies 2; the honeycomb body 2 has good water absorption and huge specific surface area; the sprayer 4 is arranged in front of the air inlet surface of the honeycomb body 2, and the water mist sprayed by the sprayer 4 can reach the air inlet surface of all the honeycomb bodies 2; the temperature and humidity control device 11 and its electrically connected sensor 12 are arranged 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 2 unit is made of sintered zeolite molecular sieve material, has a developed pore structure and a huge specific surface area, and has good water absorption and weather resistance.

[0033] In this example, the honeycomb body 2 units are installed on the bracket 3 and stacked to form a wall-like structure. The honeycomb body 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 sensor 12 connected to the temperature and humidity control device 11 is a temperature sensor, and the water spraying amount of the sprayer is controlled by the obtained temperature data to realize the cooling working mode with priority given to the air outlet temperature control.

[0036] In this example: the number of the sprayers 4 is multiple.

[0037] In this example: a connecting pipe 10 is provided below the honeycomb body 2 to connect the bottom of the air inlet end 5 and the bottom of the air outlet end 6, and a drain port 9 is provided at the bottom of the air outlet end 5, which can drain 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 arranged at the air inlet end 5 of the housing 1, and there are multiple fans.

[0039] In this example, an axial flow fan at the air inlet end is used to supply air. The fan is installed near the outdoor end to reduce indoor noise, and the heat generated by the fan motor during operation also enters the honeycomb body for cooling, thereby achieving a lower indoor temperature.

[0040] In this example, the air inlet is located in front of the air inlet surface of the honeycomb body 2, and the air inlet is straight. The air outlet is located 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 goes in and out directly under the drive of the fan.

[0041] Working principle: Figure 1-3 As shown, the working process of the present invention is as follows: start the fan and the sprayer, and the sprayer sprays water mist to the air inlet surface of the honeycomb body. Since the spraying direction is consistent with the air flow direction, the water mist enters the front honeycomb pores of the honeycomb body with the help of wind force and is absorbed. The excess or splashed water will flow down to the bottom of the honeycomb body and finally be discharged through the drain port. Driven by the fan, the external air enters from the air inlet end and passes through the honeycomb pores of the honeycomb body before being discharged, completing the cooling of the air passing through. During the whole process, the water content of the honeycomb body is controlled by the temperature and humidity control device to ensure the continuous stability of the whole refrigeration process.

[0042] Working principles of each stage in the refrigeration process of Example 1 of the present invention:

[0043] In the first stage, when the temperature at the air outlet reaches the upper limit, the sprayer starts, and the water mist contacts the air inlet surface of the honeycomb body with the wind. The moisture is absorbed by the pore wall of the front section of the honeycomb pore. In this process, the moisture does not undergo a phase change and remains in liquid form. The moisture carried by the continuing forward airflow is gradually absorbed by the honeycomb pore wall and becomes less and less. The moisture vaporization rate is low in this stage, and the latent heat effect has little effect on cooling the airflow. The main function of this stage is that the airflow transfers the liquid water it carries to the front section of the honeycomb pore wall of the honeycomb body and is absorbed by it.

[0044] In the second stage, the moisture absorbed by the front honeycomb pore wall is diffused through the capillary action formed by the developed microchannels inside the molecular sieve material. The function of this stage is to diffuse the moisture in the honeycomb body toward the air outlet direction of the honeycomb body.

[0045] The third stage: the moisture in the honeycomb body diffuses to the wall of the rear honeycomb channel and contacts the airflow again. Due to the huge specific surface area of ​​the zeolite material and the negative pressure generated by the gas flow in the honeycomb channel, the moisture in the honeycomb channel wall will be quickly vaporized. The latent heat absorption generated by the water vaporization phase change will cool the honeycomb channel wall. The role of this stage is to cool the rear honeycomb channel wall by vaporization of moisture.

[0046] The fourth stage: After the incoming airflow transfers the water mist in the front section of the honeycomb channel, it exchanges heat with the cooled honeycomb channel wall when passing through the rear section of the honeycomb channel. This stage completes the cooling of the airflow.

[0047] The fifth stage: when the temperature at the air outlet reaches the lower limit and the sprayer is closed, the honeycomb body still retains considerable moisture for a long time. In this stage, the whole or part of the honeycomb pores can maintain the refrigeration function of efficient water vaporization until the temperature reaches the upper limit (that is, the moisture in the honeycomb body is reduced to the valley value), and the next round of spraying is started and the cycle continues.

[0048] If the sprayer sprays too much or too little water on the honeycomb body, the refrigeration effect will be affected. If the spraying amount is too little, there will not be enough water to evaporate, which will reduce the refrigeration capacity. However, the spraying amount cannot be too large. On the one hand, too much water will waste water resources, and too much water may even cause liquid water to block the honeycomb pores. On the other hand, after the zeolite material is saturated with water, its surface will be covered by a water film formed by the surface tension of water, which reduces the efficient gasification effect brought about by the huge specific surface area of ​​the zeolite material. Therefore, during the refrigeration operation, the honeycomb body 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 of the air outlet 6 through the sensor 12. During operation, the water content of the honeycomb is negatively correlated with the temperature of the air outlet. When the temperature of the air outlet is at a low value, the corresponding water content of the honeycomb is high. The water vaporization rate during this period reaches a high level, which is a stage with good refrigeration efficiency. When the temperature of the air outlet is higher than the set limit, it means that the water content of the honeycomb is insufficient. At that time, it is necessary to start the sprayer to humidify the honeycomb. Therefore, the temperature and humidity control device starts and shuts down the water supply device of the sprayer according to the upper and lower limits set for the temperature of the air outlet, so as to ensure that the water content of the honeycomb is kept within a reasonable range and obtain an ideal refrigeration effect. The water spraying amount of the sprayer can be controlled by adjusting the flow control of the water supply throttle valve, or by using periodic interval spraying to control the water spraying amount. The intermittent spraying method is used to maintain the water content of the honeycomb within a certain range. As long as a reasonable proportion of water is accumulated in the honeycomb, it still has good conditions for water vaporization, and the refrigeration and humidification will not be affected during the stop of spraying.

[0049] Example 2: Figure 1 and Figure 4As shown, a water vaporization refrigeration and air-conditioning device with automatic temperature and humidity control comprises a shell 1, a fan 8, a honeycomb body 2 of a combined structure, a sprayer 4 and a temperature and humidity control device 11; the fan 8 is arranged at the air outlet 6 of the shell 1; the honeycomb body 2 of the combined structure is a combination of multiple square honeycomb body 2 units and is arranged between the air inlet 5 and the air outlet 6 in the shell 1, and the air flow from the air inlet 5 to the air outlet 6 needs to flow through the honeycomb pores of all the honeycomb bodies 2; the honeycomb body 2 has good water absorption and huge specific surface area; the sprayer 4 is arranged in front of the air inlet surface of the honeycomb body 2, and the water mist sprayed by the sprayer 4 can reach the air inlet surface of all the honeycomb bodies 2; the temperature and humidity control device 11 and its electrically connected sensor 12 are arranged at the air outlet 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.

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

[0051] In this example, the honeycomb body 2 units are installed on the bracket 3 and stacked to form a wall-like structure. The honeycomb body 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 sensor 12 connected to the temperature and humidity control device 11 is a temperature and humidity sensor, which controls the water spraying amount of the sprayer through the obtained relative humidity data, thereby realizing a humidification working mode with priority given to the relative humidity control of the air outlet.

[0054] In this example: the number of the sprayers 4 is multiple.

[0055] In this example: a connecting pipe 10 is provided below the honeycomb body 2 to connect the bottom of the air inlet end 5 and the bottom of the air outlet end 6, and a drain port 9 is provided at the bottom of the air outlet end 5, which can drain 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 arranged at the air outlet end 6 of the shell 1, the number of fans is one, and an axial flow fan arranged at the air outlet end is used for exhaust. Negative pressure exhaust can further reduce the turbulence of the air flow in the air duct and reduce the air 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 air supply.

[0057] Another difference between this example and Example 1 is that the sensor 12 connected to the temperature and humidity control device 11 is a temperature and humidity sensor, which can obtain the relative humidity value of the air outlet, so that it is convenient to directly control the relative humidity of the air outlet. The relative humidity value of the air outlet is positively correlated with the moisture content of the honeycomb body, so this example controls the water spraying amount of the sprayer by the relative humidity value to maintain the moisture content of the honeycomb body within a certain range, thereby achieving control of the relative humidity of the air outlet. Of course, in Example 2, the dry bulb temperature value in the temperature and humidity sensor can be selected for control, so that it is easy to switch from the humidification working mode with priority to the relative humidity control of the air outlet in Example 2 to the cooling working mode with priority to the air outlet temperature control in Example 1.

[0058] The working principle of each stage in the humidification process of Example 2 is basically the same as that of Example 1, except that Example 1 controls the water spraying amount of the sprayer by the temperature value of the air outlet to control the air outlet temperature within a certain range, while Example 2 controls the water spraying amount of the sprayer by the relative humidity value of the air outlet to control the relative humidity of the air outlet within a certain range.

[0059] The present invention also performs cooling during the humidification process, thereby realizing cooling and humidification at the same time. According to actual needs, a control mode with priority given to the outlet air temperature or the outlet air relative humidity can be selected, or a set value within the intersection of the two numerical ranges can be selected to realize automatic control of temperature and humidity at the same time.

[0060] From the analysis of the external structure and material properties of the honeycomb body in the above two embodiments, the honeycomb structure has a large wind spread area, and the materials used in the honeycomb body have extremely high specific surface area and dense open pores inside. The dense capillaries formed from the inside to the outside play an extremely important role in achieving rapid absorption, rapid transfer and diffusion, and rapid evaporation of water.

[0061] The present invention is different from the traditional water curtain air conditioner in terms of structure, refrigeration or humidification working principle and process, and the traditional water curtain air conditioner is difficult to achieve in terms of refrigeration performance and humidification performance.

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