Description

Technical Field

[0001] The present invention relates to the field of air curtain systems, and particularly to a mosquito repellent and temperature regulating air curtain system for windows and its control method. Background Art

[0002] Most traditional air curtain systems are designed for indoor and outdoor entrances. They usually use vertically downward airflows to separate indoor and outdoor airflows, maintain indoor temperature, and disperse mosquitoes. However, building windows are also connected to indoor and outdoor airflows and also have the need to separate indoor and outdoor airflows and disperse mosquitoes. However, when traditional air curtain systems are applied to windows, the following problems will occur:

[0003] (1) Traditional air curtain systems adopt a vertically downward air flow pattern. For a small connecting opening when the window is opened, and for a horizontal sliding window, the vertical spacing of the window body is large, and the connecting opening is a vertical rectangle. It is very energy-consuming to maintain a high-speed air flow pattern by blowing from top to bottom. At the same time, when a traditional air curtain system is used for a window, the air curtain will cover the entire window frame opening of the horizontal sliding window. However, in the case of a horizontal sliding window, a large area of the window frame area is usually isolated by the window body, and the high-speed air curtain in this part is very energy-consuming. If the air curtain is further cooled or heated, the energy consumption of this part is even higher.

[0004] (2) Traditional air curtain systems usually adopt evaporative cooling. The device for the circulation process of the coolant used has a high cost and high production cost. The entire air curtain system is large in volume, while the installation space of traditional horizontal sliding windows is limited. The cost and space constraints greatly limit the adaptability of traditional air curtain machines in the field of window air curtains.

[0005] (3) Traditional air curtain systems usually only have one layer of air curtain or simply divide the air curtain air duct into two or more layers to form two or more layers of air curtains. The multi-layer air curtains are only for improving the effect of isolating mosquitoes or indoor and outdoor temperatures, and there is no functional division for the stratified air curtains to further improve the effect of isolating mosquitoes or regulating indoor and outdoor temperatures. Traditional air curtains cannot effectively match the opening and closing of windows and the opening distance of the window body. At the same time, some air curtain systems suck in outdoor air and blow it into the room. For example, in a kind of air curtain system described in CN103471200B, when it is installed on a window, the air curtain flows obliquely into the room. When mosquitoes enter the window opening, they may be drawn into the room, and the effect of isolating mosquitoes by opening the window is not good. Summary of the Invention

[0006] The purpose of the present invention is to provide a mosquito repellent and temperature regulating air curtain system for windows and its control method to solve the above problems.

[0007] The present invention is achieved by the following technical solutions:

[0008] Generally, a mosquito repellent and temperature regulating air curtain system for windows includes a microcontroller and an air curtain device controlled by the microcontroller. The air curtain device includes two sets of horizontal fans respectively arranged on two vertical sides of the window frame. The horizontal fans can generate a horizontally flowing air curtain. By horizontally arranging the horizontal fans on two vertical sides of the window frame, the opening and closing of the window can be used to control the start of the horizontal fans. That is, when the window is opened on one side, the horizontal fan on that side is started, and when the window is not opened, the corresponding horizontal fan is not opened. Compared with the traditional rough air curtain that covers the entire window frame, the present invention uses less air curtain to achieve the same effect, saving more energy. A flow splitting component is arranged at the air outlet of the horizontal fan. The flow splitting component divides the air outlet of the horizontal fan into an inner air duct close to the window frame side and an outer air duct far from the window frame side. The air duct opening of the inner air duct faces the inner side of the window. The inner air curtain generated by the inner air duct can flow into the room through the opened window. The opening of the outer air duct faces the outer side of the window. The outer air curtain generated by the outer air duct flows outside the window. By splitting the air curtain into an inner air curtain blowing into the room and an outer air curtain blowing horizontally outside the window, the inner air curtain blowing into the room can block the indoor temperature from overflowing to the outside, and at the same time, the outer air curtain can block mosquitoes outside. An opening and closing component is arranged on the outer air duct of the horizontal fan. The opening and closing component can close the air outlet of the outer air curtain. The horizontal fan is also provided with a cooling component. The cooling component first cools the air curtain through fog mixing and then through wet curtain volatilization. Through these two cooling means, in a limited space and cooling time, the temperature of the inhaled air can be quickly lowered by water mist and wet curtain, which is suitable for the narrow working space of the horizontal fan. The two sets of horizontal fans can generate an air curtain with any number of paths from one to four. When only one side of the window is opened and the outdoor temperature is extremely low (no mosquitoes outside), one side of the horizontal fan can be started and the outer air duct can be closed to form an air curtain with one path. When both sides of the window are opened, the indoor and outdoor temperatures are suitable, but the opening distance on one side is too small (for example, a crack is opened), and the opening distance on the other side is large. Then, on the side of the horizontal fan with a small opening distance, only the inner air duct can be used (the inner air curtain is not enough to enter the room and hits the side of the window. At the same time, the inner air duct is close to the high wind pressure, which is enough to repel insects and isolate the indoor and outdoor airflows). The other side uses a double air duct to form an air curtain with three paths. When one side is normally opened, both sides are normally opened, and the indoor and outdoor temperatures are suitable, two-path and four-path air curtains can be correspondingly formed. By flexibly setting the number of air curtain paths, it further fits the opening and closing of the window, saves energy, avoids the use of ineffective air curtains, and saves energy.

[0009] Further, the horizontal fans are vertically arranged along the edge of the window frame. The driving motors of the horizontal fans are arranged at the lower ends of the horizontal fans, and the impellers are arranged inside the casings of the horizontal fans. By vertically arranging the horizontal fans, the horizontal fans generate a horizontally flowing air curtain.

[0010] Preferably, an air filter cover is provided at the air inlet of the impeller of the cross-flow fan, and a wet curtain is further provided inside the air filter cover. The space between the air filter cover and the wet curtain forms a vertical cavity. By providing the air filter cover, the air inhaled by the cross-flow fan is filtered and cleaned. By further providing a layer of wet curtain inside the filter cover and forming a vertical cavity, a certain mixing space is provided for the mixing of water mist and filtered air.

[0011] Preferably, an electric control water mist nozzle is provided on the inner wall of the casing at the top of the vertical cavity. The electric control water mist nozzle can spray water mist downward. By providing the water mist nozzle at the top of the vertical cavity, the water mist fills the entire vertical cavity through the spraying pressure and gravity. At the same time, when the cross-flow fan starts, the vertical cavity is in a negative pressure relative to the outside of the air filter cover, and there is continuous air pressure outside the air filter cover, preventing the water mist from overflowing from the air filter cover. The air mixed with the water mist in the vertical cavity is cooled by the first water mist mixing. The water mist further flows inward through the negative pressure generated by the impeller and wets the wet curtain. The air after the first cooling passes through the wet curtain again and further volatilizes for the second wet curtain volatilization cooling. The air after the two coolings then flows out through the inner and outer air ducts to form inner and outer air curtains. Through the two-stage cooling design, the cross-flow fan can complete efficient cooling in a narrow space and a short time to form a cold air curtain.

[0012] Preferably, a heating component is provided on the side of the flow splitting component close to the inner air duct. The heating component is attached with a heat dissipation row on one side of the inner air duct. The heating component heats the inner air duct through the heat dissipation row. By splitting the air duct into a double air duct through the flow splitting component and setting a heating component at the air outlet of the inner air duct at the same time, the air flow passing through the inner air duct is heated at the air outlet of the air duct and then directly flows into the room, avoiding the waste caused by directly heating the air inside the cross-flow fan and flowing out from the outer air duct.

[0013] Preferably, the air outlets of the inner air duct and the outer air curtain are gradually contracted corresponding to the air inlets to compress the air flow generated by the impeller and increase the wind speed. The contraction amplitude of the inner air duct for the air flow is greater than that of the outer air duct. By making the contraction amplitude of the inner air duct greater than that of the outer air duct, the air pressure of the inner air duct is greater than that of the outer air duct. The mainstream horizontal sliding windows are usually in a suspended state on the outside. When there is an air curtain on the outside, the air pressure of the high-speed flowing air outside the window will be less than the air pressure inside the room, which is essentially different from the traditional curtain fan used at the door that blows towards the ground and then the air curtain diffuses indoors and outdoors. In order to prevent the indoor air from being pumped out and causing changes in the indoor temperature, setting an inner air duct that blows towards the room and increasing the air pressure of the inner air duct can effectively solve this problem. By regulating the temperature of the inner air duct through the heating component of the inner air duct and the cooling component of the cross-flow fan (the cooling component reduces the air curtains of both air ducts at the same time, and the heating component only heats the inner air curtain), it is possible to make the inner air duct flow out a cold air curtain or a hot air curtain according to needs, and further cooperate to adjust the indoor air temperature.

[0014] Preferably, a control method is implemented using the air curtain system of the present invention, and the steps are as follows:

[0015] Step 1: The microcontroller determines whether the current state is manual control or automatic control. When the current state is manual control, the microcontroller waits to receive an instruction and controls the horizontal fan to act according to the instruction. When the current state is automatic control, proceed to the next step. Through the settings of manual control and automatic control, it better meets the actual usage requirements in the air curtain field and can independently select the operation mode according to the user's economic adaptability, enabling the present invention to have good economic adaptability;

[0016] Step 2: The distance sensors arranged on both sides of the window frame by the microcontroller collect the window opening distance parameters, and the temperature sensors arranged indoors and outdoors by the microcontroller collect the indoor and outdoor temperature parameters. Then, the appropriate temperature parameters preset in the microcontroller and the preset mosquito activity threshold temperature are read. By collecting the necessary parameters, it provides data support for the next automatic action;

[0017] Step 3: According to the window opening distance parameters, indoor and outdoor temperature parameters, appropriate temperature parameters, and mosquito activity threshold temperature described in Step 2, the corresponding actions of the horizontal fan are adjusted. By using the parameters obtained in Step 2 to adjust the corresponding actions of the horizontal fan, the usage cost of the operator is reduced, and the scene adaptability of the present invention is improved.

[0018] Preferably, in the manual control state in Step 1, the instructions include

[0019] Instruction 1: Turn on or off any horizontal fan on either side of the horizontal of the window frame, and several subsequent instructions can be used to control any horizontal fan. Through this instruction, the operator can customize the turning on or off of the horizontal fan;

[0020] Instruction 2: The instruction for the wind force of the horizontal fan, which is achieved by the microcontroller controlling the rotation speed and power of the drive motor. Through this instruction, the rotation speed of the impeller of the horizontal fan is controlled, and then the flow rates of the inner and outer air curtains are controlled, so as to cooperate with the window opening distance. When the window opening distance is short, the wind speed is reduced, thereby saving energy;

[0021] Instruction 3: The cooling and heating instructions, which are achieved by the microcontroller controlling the injection of water mist by the electric control water mist nozzle and the shutdown of the heating component;

[0022] Instruction 4: The cooling and heating efficiency instructions. The cooling power parameter controls the cooling efficiency by changing the wind force of the horizontal fan and the flow rate of the electric control water mist nozzle, and the heating power parameter controls the heating efficiency by changing the wind force of the horizontal sewing machine and the power of the heating component;

[0023] Instruction 5: The opening and closing instruction of the outer air duct opening and closing component, which is achieved by the microcontroller controlling the electric drive device arranged at the end of the opening and closing component.

[0024] Preferably, the specific implementation steps of Step 3 are as follows:

[0025] Step 1: Judge the mosquito repelling situation through Step 1, and select to turn on the cross fan, turn off the cross fan, or turn off the cross fan as appropriate:

[0026] When the outdoor temperature is lower than the mosquito activity threshold temperature, the microcontroller turns on the cross fan on the opened side of the window, closes the outer air duct of the cross fan, and adjusts the air curtain flow rate of the cross fan according to the opening distance of the window. By closing the outer air duct, the air flow of the entire impeller enters the room through the inner air duct, reducing the ineffective energy consumption while increasing the air pressure in the inner air duct. Furthermore, the impeller speed can be appropriately reduced to further reduce energy consumption; the air curtain flows into the room through the inner air duct to prevent the indoor temperature from overflowing with the indoor air flow; the impeller speed is adjusted according to the opening distance of the window, thereby changing the air curtain flow rate, and the refined management saves the energy wasted by the rough management of the traditional air curtain machine;

[0027] When the outdoor temperature is higher than the mosquito activity threshold temperature, the microcontroller turns on the cross fan on the opened side of the window and opens the outer air duct of the cross fan, and adjusts the air curtain flow rate of the cross fan according to the opening distance of the window. By opening the outer air duct, the outer air curtain keeps flowing continuously, thereby effectively repelling mosquitoes;

[0028] Step 2: Further judge the temperature regulation situation through Step 2, and adjust the heating component or cooling component set corresponding to the cross fan. The temperature regulation further controls the actions corresponding to the cross fan started in Step 1:

[0029] The microcontroller judges the magnitude relationship between the indoor temperature and the suitable temperature.

[0030] When the indoor temperature is lower than the suitable temperature:

[0031] Further judge the magnitude relationship between the outdoor temperature and the suitable temperature:

[0032] When the outdoor temperature is lower than the suitable temperature, the microcontroller controls the heating component to heat the inner air duct of the cross fan. By heating the inner air duct through the heating component, hot air flows into the room through the inner air curtain when the window is opened, raising the indoor temperature and improving the indoor air quality;

[0033] When the indoor temperature is equal to the suitable temperature:

[0034] Further judge the magnitude relationship between the outdoor temperature and the suitable temperature:

[0035] When the outdoor temperature is lower than the suitable temperature, the microcontroller controls the heating component to heat the inner air duct of the cross fan;

[0036] When the outdoor temperature is higher than the suitable temperature, the microcontroller controls the electronically controlled water mist nozzle to spray water mist to cool the inner air curtain and the outer air curtain. By cooling the inner air curtain and the outer air curtain, the cold air of the inner air curtain is blown into the room, and the cold air of the outer air curtain drives away mosquitoes and at the same time blocks the outdoor hot air from pouring into the room, so that the opened window forms a cold air outlet;

[0037] When the indoor temperature is greater than the suitable temperature:

[0038] The microcontroller controls the electronically controlled water mist nozzle to spray water mist to cool the inner air curtain and the outer air curtain.

[0039] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0040] 1. By vertically arranging cross-flow fans on both sides of the window frame, the cross-flow fans on both sides of the window can select to drive the cross-flow fans to generate a transverse air curtain according to whether the two side window panes are opened. At the same time, the flow rate of the transverse air curtain can be adjusted corresponding to the opening distance of the window pane. When the opening distance of the window pane is small, the flow rate of the transverse air curtain of the cross-flow fan is correspondingly reduced. Compared with the traditional method of using a high-speed air curtain from top to bottom to ensure that the entire window is covered by the air curtain, the flexible adjustment of the present invention saves more energy;

[0041] 2. The vertically arranged cross-flow fan of the present invention is provided with an air filter cover, and a wet curtain is arranged inside the air filter cover. The gap between the wet curtain and the air filter cover forms a vertical cavity. An electronically controlled water mist nozzle is arranged inside the casing at the top of the vertical cavity. When the cross-flow fan starts and the temperature control component is started, the electronically controlled water mist nozzle sprays water mist into the vertical cavity. The water mist mixes with the inhaled air inside the vertical cavity to cool the air for the first time. The water mist and air mixture are attracted by the impeller and penetrate the wet curtain again. The water mist is absorbed by the wet curtain and wets the wet curtain. When the air penetrates the wet curtain, the moisture of the wet curtain further volatilizes and absorbs heat to cool the water mist again. Through the two-stage cooling setting, the cross-flow fan can complete efficient cooling with very low energy consumption in a short time and in a narrow space. The low-cost and small-space characteristics of the cooling component make the present invention have better adaptability in the field of window air curtains compared with traditional air curtains;

[0042] 3. The present invention adopts a diversion component to divide the wind duct of the horizontal fan into an inner duct and an outer duct, and generates an inner wind curtain and an outer wind curtain accordingly. The inner wind curtain is tilted horizontally to flow into the room to prevent the indoor temperature from overflowing to the outside. The outer wind curtain is tilted horizontally in accordance with the window and can effectively repel mosquitoes. At the same time, the contraction range from the air inlet to the air outlet of the inner duct is greater than that of the outer duct. This setting makes the wind pressure of the inner wind curtain greater than that of the outer wind curtain, effectively preventing the negative pressure formed by the outer wind curtain flowing outside the window relative to the room from affecting the indoor air (similar to the negative pressure outside the window sucking out the air in the airplane after the window is opened). At the same time, the heating component arranged for the inner duct is directly heated by the heat sink arranged at the inner duct opening, avoiding the waste of heat caused by the heating inside the horizontal fan to diffuse to the outer wind curtain, reducing the distance of the heated airflow flowing in the horizontal fan equipment, and reducing the heat loss in the equipment.

It should be noted that in this embodiment, the microcontroller 3 uses the STM32F105 interconnected single-chip microcomputer as the control brain. At the same time, temperature sensors are arranged on both the indoor and outdoor sides of the window frame 101 corresponding to the microcontroller 3 to read the indoor and outdoor temperatures.

It is worth mentioning that the microcontroller 3 is not within the scope of the distinguishing features of this embodiment based on the mature technical foundation, and the model of the microcontroller 3 and the arrangement position of the sensors are not limited by this embodiment.

[0055] Embodiment:

[0056] As Figures 1 to 9As shown, this embodiment includes a cross-flow horizontal fan 2 arranged on two vertical sides of an outdoor window frame 101 and a microcontroller 3 arranged on the indoor window frame 101. The horizontal fans 2 on both sides of the window frame 101 are arranged vertically, and an air filter cover 201 is arranged at the air inlet of the vertically arranged horizontal fan 2 casing. A layer of wet curtain 202 is arranged inside the air filter cover 201. The gap space between the wet curtain 202 and the air filter cover 201 forms a vertical cavity. An electrically controlled water mist nozzle is arranged on the top of the vertical cavity. The electrically controlled water mist nozzle is composed of a booster valve 2016 and a water mist nozzle 2013. The microcontroller 3. The control boost valve 2016 is used to shut off the connection between the control water pipe 2017 and the water mist nozzle 2013, and the water mist spray flow rate of the water mist nozzle 2013 is adjusted by controlling the boost valve 2016 valve; the impeller 203 of the horizontal fan 2 is arranged on the inner side of the wet curtain 202, and the impeller 203 of the horizontal fan 2 rotates to make the air pass through the air filter cover 201 first and then penetrate the wet curtain 202, and is accelerated by the impeller 203 to be ejected from the air duct of the horizontal fan 2. The air duct of the horizontal fan 2 is provided with a diversion component, which is composed of a diversion substrate 208 and a heating component. The diversion substrate 208 divides the air duct into two parts: The inner air duct 2015 near the window frame 101 and the outer air duct 2014 far away from the window frame 101, at the same time, the air inlet positions of the outer air duct 2014 and the inner air duct 2015 are gradually contracted relative to the air outlet position, and the contraction ratio of the inner air duct 2015 is greater than the contraction ratio of the outer air duct 2014. The back side of the substrate of the shunt substrate 208 close to the inner air duct 2015 side is fitted with a heating component, and the heating component includes an electric heating block, an electric heating wire 206 and a temperature insulation layer 207. The electric heating block is fitted with the back side, and a plurality of vertical wire holes are arranged inside the electric heating block, and the electric heating wire 206 passes through the back side of the substrate. The surface of the electric heating block is provided with a temperature insulating layer 207, which is used to reduce the temperature diffusion of the electric heating block. The shunting substrate 208 is provided with a heat sink 205 near the inner air duct 2015. The heat sink 205 absorbs the temperature of the heating block of the heating component and heats the airflow passing through the inner air duct 2015. The horizontal fan 2 forms two layers of wind curtains through the inner and outer air ducts separated by the shunting component. The wind curtain planes of the two layers of wind curtains form an angle, wherein the inner wind curtain formed by the inner air duct 2015 is tilted to blow indoors, and the outer wind curtain formed by the outer air duct 2014 is tilted away to form an outdoor wind curtain.The external air duct 2014 is provided with an opening and closing assembly corresponding to the external air duct 2014, and the opening and closing assembly is composed of a rotary plate 209 provided inside the external air duct 2014, a rope 2010, a twist shaft 2011 and a twist shaft motor 2018. The rotary plate 209 is vertically provided inside the external air duct 2014, and a rotating shaft is fixed on a vertical edge on one side. The rotating shaft is close to the side of the diversion substrate 208 of the external air duct 2014, and is connected to the casing of the upper and lower ends of the horizontal fan 2 in the vertical direction, and can rotate relative to the casing. A sliding shaft is fixed on the other side of the rotary plate 209, and the sliding shaft corresponds to the sliding shaft provided at the upper and lower ends of the horizontal fan 2. The guide sliding of the moving groove 2012 and the middle position of the sliding shaft are provided with multiple groups of ropes 2010, and the other end of the rope 2010 is connected to the rope shaft 2011 provided on the other side of the diversion substrate 208 of the outer air duct 2014. The rope shaft 2011 rotates, the rope 2010 winds and pulls the sliding shaft of the rotating plate 209 to complete the closing action. On the contrary, the rope 2010 is released, and the airflow flowing in the outer air duct 2014 pushes the rotating plate 209 away by itself; the horizontal fan motor 219 is provided at the bottom of the horizontal fan 2, and the horizontal fan motor 219 drives the impeller 203 to rotate. ;

[0057] Example under manual control:

[0058] When the single-side window 102 is opened, the horizontal fan 2 on that side is manually controlled to start. When the outside temperature is high (physiological overheating), the electrically controlled water mist nozzle of the horizontal fan 2 is turned on to fill the vertical cavity between the air filter cover 201 of the horizontal fan 2 and the wet curtain 202 with water mist. The water mist is highly mixed with the air sucked into the vertical cavity, and the sucked air is cooled down for the first time. The negative pressure generated by the impeller 203 of the horizontal fan 2 continuously sucks in the outside air, and the outside air suppresses the water mist from overflowing from the air filter cover 201 outside the vertical cavity, and suppresses the water mist. The mist penetrates the wet curtain 202. During the process of air penetrating the wet curtain 202, the moisture in the mist penetrates the wet curtain 202 and evaporates again, further cooling the air sucked in by the horizontal fan 2. The cooled cold air is blown out from the internal and external air ducts 2014. The cold air curtain blown out of the internal air duct 2015 tilts and flows into the room, improving the indoor temperature. The cold air curtain blown out of the external air duct 2014 tilts away from the window 102 to drive away mosquitoes. The internal and external cold air curtains form a cold air barrier relative to the indoor and outdoor as a whole, blocking the influence of the external temperature on the indoor.

[0059] When the single-side window 102 is opened, the horizontal fan 2 on that side is manually controlled to start, and the outside temperature is low (physiologically perceived as too cold, such as below zero in winter). At this moment, if the temperature is lower than the mosquito activity temperature threshold, the external air duct 2014 opening and closing component is controlled to close the external air duct 2014, so that the horizontal fan 2 only generates the inner wind curtain to reduce energy consumption, and the heating component is started to heat the inner wind curtain, so that a layer of heating barrier is formed indoors and outdoors on the side where the window 102 is opened;

[0060] When the single-sided window 102 is opened, manually control the horizontal fan 2 on that side to start. When the external temperature is suitable (physiologically perceived as comfortable), the outdoor air flow is poured into the room through the inner air duct 2015 of the horizontal fan 2, and the mosquitoes are dispelled by the air curtain through the outer air duct 2014;

[0061] When the double-sided window 102 is opened, turn on the horizontal fans 2 on both sides. When the opening distance of one side window 102 is extremely small (the inner air duct 2015 is not enough to enter the room and the air curtain hits the glass of the window 102), close the outer air duct 2014 of the horizontal fan 2 on that side. When the opening distance of the other side is larger, turn on the outer air curtain of the horizontal fan 2 to form a three-way air curtain to reduce energy consumption;

[0062] When the double-sided window 102 is opened, customize the control according to the operator's habit. It is worth mentioning that the heating component, the electric control water mist nozzle, and the flow rate of the horizontal fan 2 in the embodiment are respectively provided with three levels of heating power, two levels of flow rate, and three levels of wind speed. In the manual control mode, the operator adjusts according to actual needs. At the same time, the embodiment uses the microcontroller 3 directly operated on the inner side of the window frame 101 to control the horizontal fan 2, but it does not represent the possible iterative use of mobile wireless control in the later embodiment. The embodiment does not limit the manual control method.

[0063] Under the automatic control of the embodiment:

[0064] The operator presets the mosquito activity threshold temperature to 18 degrees Celsius, and the suitable temperature is 23 to 25 degrees Celsius

[0065] First step, the microcontroller 3 makes a judgment on mosquito dispelling:

[0066] When the outdoor temperature is lower than the mosquito activity threshold temperature, turn on the horizontal fan 2 on the opened side of the window 102 through the microcontroller 3 and close the outer air duct 2014 of the horizontal fan 2. At the same time, divide the horizontal distance of one side of the window 102 into three equal sections. When the opening distance of the window 102 is less than two sections, adjust the rotation speed of the impeller 203 of the horizontal fan 2 to low speed. When the opening distance of the window 102 is greater than two sections, adjust the rotation speed of the impeller 203 of the horizontal fan 2 to medium speed. It is worth mentioning that after closing the outer air duct 2014, the inner air duct 2015 still has a relatively high air pressure when the impeller 203 uses a low rotation speed;

[0067] When the outdoor temperature is higher than the mosquito activity threshold temperature, turn on the horizontal fan 2 on the opened side of the window 102 through the microcontroller 3 and open the outer air duct 2014 of the horizontal fan 2. At the same time, divide the horizontal distance of one side of the window 102 into three equal sections. When the opening distance of the window 102 is less than one section, adjust the rotation speed of the impeller 203 of the horizontal fan 2 to low speed. When the opening distance of the window 102 is greater than one section and less than two sections, adjust the rotation speed of the impeller 203 of the horizontal fan 2 to medium speed. When the distance of the window 102 is greater than two sections, adjust the rotation speed of the impeller 203 of the horizontal fan 2 to high speed;

[0068] In the second step, the microcontroller 3 makes a temperature regulation judgment, and the temperature regulation action corresponds to further action control of the cross-flow fan 2 started in the first step. The microcontroller 3 judges the magnitude relationship between the indoor temperature and the suitable temperature.

[0069] When the indoor temperature is lower than the suitable temperature:

[0070] Further judge the magnitude relationship between the outdoor temperature and the suitable temperature:

[0071] When the outdoor temperature is lower than the suitable temperature, the microcontroller 3 controls the heating component to heat the inner air duct 2015 of the cross-flow fan 2. When the outdoor temperature is lower than 0 °C, the heating component uses a high heating power (800 W). When the outdoor temperature is higher than 0 °C and lower than 18 °C, the heating component uses a medium heating power (500 W). When the outdoor temperature is higher than 18 °C and lower than 23 °C, the heating component uses a low heating power (300 W);

[0072] When the indoor temperature is equal to the suitable temperature:

[0073] Further judge the magnitude relationship between the outdoor temperature and the suitable temperature:

[0074] When the outdoor temperature is lower than the suitable temperature, the microcontroller 3 controls the heating component to heat the inner air duct 2015 of the cross-flow fan 2. When the outdoor temperature is lower than 0 °C, the heating component uses a high heating power. When the outdoor temperature is higher than 0 °C and lower than 18 °C, the heating component uses a medium heating power. When the outdoor temperature is higher than 18 °C and lower than 23 °C, the heating component uses a low heating power;

[0075] When the outdoor temperature is higher than the suitable temperature, the microcontroller 3 controls the electric control water mist nozzle to spray water mist to cool the air curtains of the inner and outer air ducts. When the outdoor temperature is higher than 25 and lower than 30 degrees, the valve flow rate of the pressure increasing valve 2016 is controlled for low-flow spraying. When the outdoor temperature is higher than 30 degrees, the valve of the pressure increasing valve 2016 is controlled for standard-flow spraying (the standard flow rate is greater than the low flow rate);

[0076] When the indoor temperature is higher than the suitable temperature:

[0077] The microcontroller 3 controls the electric control water mist nozzle to spray water mist and performs standard-flow spraying to cool the air curtains of the inner and outer air ducts and regulate the indoor temperature.
