Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning, in particular to a multifunctional heat dissipation device, system, control method and air conditioner. BACKGROUND

[0002] In modern life, with the trend of global warming, high-temperature weather is becoming more frequent, and users' performance requirements for air conditioners are also increasing, especially in high ambient temperature conditions. As a key device for adjusting indoor temperature, the performance of the air conditioner directly affects the comfort and quality of life of users. However, under high-temperature working conditions, the operation of the air conditioner faces a series of challenges.

[0003] On the one hand, in order to ensure the refrigeration effect of the air conditioner, the user expects the compressor to maintain a high operating frequency. However, the increase of the compressor frequency will cause the temperature rise of the internal and surrounding components to exceed the standard, which not only affects the service life of the components, but also may trigger the protection mechanism, causing the compressor to operate at a lower frequency, thereby reducing the refrigerating capacity. On the other hand, as the ambient temperature rises, the load of the outdoor unit increases significantly, which further limits the upward space of the compressor frequency. For the integrated air conditioner, it is a complex and difficult problem to achieve high-efficiency refrigeration under limited heat dissipation conditions.

[0004] In order to cope with these challenges, the existing integrated air conditioner adopts a variety of heat dissipation means. For example, water is sprayed onto the condenser by using axial flow fan blades, and the heat is absorbed by the evaporation of water to reduce the temperature of the condenser, thereby reducing the load of the outdoor unit. At the same time, the electrical box is usually equipped with heat dissipation fins to increase the heat exchange area between the components and the air, and to improve the heat dissipation efficiency. Under normal working conditions, these measures can maintain the normal operation of the compressor frequency and ensure the refrigeration effect of the air conditioner.

[0005] However, when the outdoor temperature is extremely high, the effect of these heat dissipation means is limited. Since the electrical box usually adopts a sealed structure, the heat carried away by the air through the heat dissipation fins is limited, and the temperature of the components cannot be effectively reduced. In order to avoid the temperature rise of the components exceeding the standard, the compressor frequency has to be lowered to a lower level, which directly leads to a decrease in refrigerating capacity and cannot meet the user's refrigeration demand. At the same time, the effect of water evaporation heat absorption outside is also limited, which cannot effectively reduce the load of the outdoor unit, further limiting the increase of the compressor frequency.

[0006] To solve this problem, Patent No. CN114144030A proposes a new heat dissipation device and its control method. The device is connected to the refrigerant circuit in the air conditioning unit by setting up the heat dissipation fin and the heat dissipation pipe, making the low-temperature refrigerant flow in the heat dissipation pipe and exchange heat with the heat dissipation fin, thereby reducing the surface temperature of the components. This solution improves the heat dissipation effect to some extent and effectively cools the frequency converter box. However, this method also has certain drawbacks, i.e., directly using refrigerant for heat dissipation will lose part of the cooling capacity, which will adversely affect the overall refrigeration effect of the air conditioner.

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the scope of protection of the present application.

[0042] It should be understood that the terms “include” and “contain” as used in the present specification and the appended claims indicate the presence of described features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or collections thereof.

[0043] It should also be understood that the terms used in the present specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the present specification and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0044] It should be further understood that the term "and / or" as used herein in the specification and in the claims, unless otherwise specified, is used to associate one or more of the items listed together, and all possible combinations of these items. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the application, as claimed.

[0045] Referring to Figures 1-3 The embodiment provides a multifunctional heat dissipation device, which comprises a shell 1, a water pumping assembly 2 and an atomization assembly 3. The shell 1 is provided with a water inlet 11 and a mist outlet 12 for sending mist to a condenser 4 and an electrical box 5. The water pumping assembly 2 and the atomization assembly 3 are installed in the shell 1. One end of the water pumping assembly 2 corresponds to the water inlet 11, the other end of the water pumping assembly 2 corresponds to an input port of the atomization assembly 3, and an output port of the atomization assembly 3 corresponds to the mist outlet 12, so that the water pumping assembly 2 pumps atomized liquid from the water inlet 11 into the atomization assembly 3 for atomization and then discharges the atomized liquid from the mist outlet 12.

[0046] When the water pumping assembly 2 is started, it sucks atomized liquid from the water inlet 11 and transports the atomized liquid to the atomization assembly 3. In the atomization assembly 3, the liquid is converted into fine mist droplets. The formed mist droplets are discharged through the mist outlet 12 and guided to the vicinity of the condenser 4 and the electrical box 5. The mist droplets evaporate rapidly after contacting the surfaces of these heat sources and absorb a large amount of heat, thereby reducing the temperature.

[0047] In the embodiment, micron-level particles generated by atomization are sent to the electrical box 5 and the condenser 4, so that the contact area is effectively increased, the evaporation heat absorption efficiency is improved, the temperature of the target area can be quickly reduced, and the problems of difficult heat dissipation of the electrical box 5 and heavy outdoor load under high-temperature working conditions can be effectively solved.

[0048] In the embodiment, referring to Figures 1-4 The shell 1 comprises a water storage cavity shell 13, an atomization cavity shell 14 and a mist cavity shell 15 which are sequentially communicated. The water inlet 11 is arranged on the water storage cavity shell 13. The water storage cavity shell 13 is provided with a water storage cavity 131 which is communicated with the water inlet 11. The water pumping assembly 2 is installed in the water storage cavity 131. The atomization cavity shell 14 is provided with an atomization cavity 141. The atomization assembly 3 is installed in the atomization cavity 141. The mist outlet 12 is arranged on the mist cavity shell 15. The mist cavity shell 15 is provided with a mist cavity 151 which is communicated with the mist outlet 12. The water storage cavity 131, the atomization cavity 141 and the mist cavity 151 are sequentially communicated.

[0049] The water storage cavity 13 is used to store water to be atomized. The water pump assembly 2 is installed in the water storage cavity 131 to pump water from the water inlet 11 to the next stage. The atomization cavity 14 is provided with the atomization assembly 3 to convert the water from the water storage cavity 131 into fine mist. This process can be achieved by ultrasonic vibration, high-pressure nozzle, etc. The mist cavity 15 is used to collect and temporarily store the atomized water vapor. The mist is guided to the condenser 4 and the electrical box 5, etc. by the mist outlet 12.

[0050] In this embodiment, the water storage cavity 13 is provided with a water supplement port 132 (as shown in Figure 2 The water supplement port 132 is in communication with the water storage cavity 131.

[0051] The design of the water supplement port 132 enables the system to continuously obtain sufficient water source, ensuring long-term atomization cooling effect. At the same time, it avoids the interruption of the system caused by water shortage, improves the reliability and stability of the air conditioner in high temperature environment. In addition, stable water supply supports efficient atomization cooling, which helps to improve the overall energy efficiency ratio of the air conditioning system.

[0052] Preferably, the water supplement port 132 can be externally connected to a water supplement tank or a water supplement pipe (not shown in the figure).

[0053] When the water supplement tank is selected, the user can place the water supplement tank in a suitable position near the air conditioner. The water supplement tank usually has a water outlet connected to the water supplement port 132 through a hose or pipe. The length and diameter of the hose or pipe can be customized according to actual needs to ensure smooth water flow. During connection, the user only needs to insert one end of the hose or pipe into the water outlet of the water supplement tank, connect the other end to the water supplement port 132, and tighten the connecting nut or buckle to complete the connection of the water supplement tank.

[0054] When the water supplement pipe is selected, the user can directly connect the water supplement pipe to the water supplement port 132. The water supplement pipe is usually a pipe directly drawn from a water source (such as a faucet, a water tank, etc.). Its diameter and length can also be customized according to actual needs. During connection, the user only needs to connect one end of the water supplement pipe to the water source, insert the other end into the water supplement port 132, and tighten the connecting nut or buckle to complete the connection of the water supplement pipe.

[0055] In this embodiment, the water storage cavity 13 is provided with a filter structure 133 (as shown in Figure 2 The filter structure 133 is located at the position corresponding to the water inlet 11.

[0056] The filtering structure 133 can ensure that all water sources flowing into the water storage cavity shell 13 through the water inlet 11 must first pass through the filtering structure 133. This design aims to effectively intercept and remove impurities, particulate matter or other potential contaminants in the water, thereby avoiding clogging of the atomization assembly 3.

[0057] The filtering structure 133 can be a filter screen or a filter cartridge or other filtering structure 133.

[0058] In this embodiment, the side wall of the water storage cavity shell 13 is provided with an assembly groove 134 (as shown in Figure 2 The control module 6 (as shown in Figure 2 is used to control the entire atomization assembly 3 to operate according to a set program.

[0059] The design of the assembly groove 134 fully considers the convenience and stability of the installation of the control module 6. Its shape is similar to that of the control module 6 to ensure that the control module 6 can be tightly and firmly embedded therein, avoiding shaking or falling off during operation. At the same time, the edges of the assembly groove 134 are treated with smooth transition, which not only protects the control module 6 from physical damage, but also facilitates the installation and disassembly operations of the user.

[0060] In this embodiment, the water pumping assembly 2 is a water pumping runner, which is embedded in the water inlet 11 at the water pumping end, so as to contact more condensed water and improve the water pumping efficiency. The water storage cavity 131 has a certain volume for accumulating the atomized liquid pumped up by the water pumping runner.

[0061] The water pumping runner forms a low-pressure area in the water storage cavity 131 through high-speed rotation, and the atmospheric pressure presses the atomized liquid into the water storage cavity 131 through the water inlet 11.

[0062] The water pumping assembly 2 can also be an electric water pump and a magnetic water pump, or other devices or structures that can pump the atomized liquid from the water inlet 11 to the water storage cavity 131.

[0063] The water pumping runner atomizes the atomized liquid pumped by the water inlet 11. If there is insufficient atomized liquid near the water inlet 11, the water pumping runner will pump the atomized liquid from the water storage cavity 131 for atomization. If there is insufficient atomized liquid in the water storage cavity 131, the water inlet 132 will be opened and the water storage cavity 131 will be supplemented with atomized liquid to meet the entire cooling process.

[0064] In this embodiment, please refer to Figure 5 The water inlet 142 is provided on the atomization cavity shell 14 and communicates with the atomization cavity 141. The water inlet 142 is provided corresponding to the input port of the atomization assembly 3.

[0065] By directly connecting the water inlet 142 to the input port of the atomizer assembly 3, intermediate links are eliminated, reducing the risk of waterway blockage or leakage, and ensuring stable operation of the system. The direct connection between the water inlet 142 and the atomizer assembly 3 simplifies the waterway structure, reduces the use of pipes, and makes the entire system more compact and simple.

[0066] One of the atomizing chamber housing 14 and the atomizing assembly 3 is provided with a positioning member 143 , and the other is provided with a positioning hole 31 . When the positioning member 143 is inserted into the positioning hole 31 , the atomizing chamber housing 14 and the atomizing assembly 3 are positioned.

[0067] In the atomizing chamber housing 14 and the atomizing assembly 3, one of them is selected to be designed with a positioning member 143. The positioning member 143 can be a small cylinder, a pin or other appropriately shaped protruding structure protruding from the inner wall or outer wall of the atomizing chamber housing 14. Next, in the atomizing chamber housing 14 and the atomizing assembly 3, another one is selected to be designed with a positioning hole 31. The shape, size and depth of the positioning hole 31 match the positioning member 143 so that the positioning member 143 can be smoothly and firmly inserted therein. The edges of the positioning hole 31 are smoothed to reduce friction during assembly while ensuring the accuracy of positioning.

[0068] During assembly, align the atomizer assembly 3 with the atomizer chamber housing 14 so that the positioning hole 31 is aligned with the positioning member 143. Then, gently push the atomizer assembly 3 to allow the positioning member 143 to smoothly insert into the positioning hole 31. Once the positioning member 143 is fully inserted into the positioning hole 31, the tight fit between the two effectively prevents the atomizer assembly 3 from moving relative to the atomizer chamber housing 14, thereby achieving precise positioning and a secure connection between the two.

[0069] The atomizing assembly 3 can be an ultrasonic atomizer assembly, a compression atomizer assembly, or a mesh atomizer assembly. Preferably, the atomizing assembly 3 is an ultrasonic atomizer assembly, which utilizes the principle of ultrasonic vibration to break water or other liquids into tiny droplets through high-frequency vibration. This atomization method has the advantages of high atomization efficiency, uniform and fine droplets, and low noise. At the same time, the ultrasonic atomizer assembly is relatively small in size, which can reduce the volume of the product.

[0070] In this embodiment, please refer to Figure 4 The mist outlet 12 includes: a condenser mist outlet 121 and an electrical box mist outlet 122, and the multifunctional heat dissipation device also includes a mist outlet pipe 7 (such as Figure 3 As shown), one end of the mist outlet pipe 7 is connected to the mist outlet 122 of the electrical box, and the other end of the mist outlet pipe 7 is arranged toward the electrical box 5. A mist dividing piece 152 is provided in the mist cavity shell 15 to divide the mist cavity 151 into a condenser mist cavity and an electrical box mist cavity. The condenser mist outlet 121 is communicated with the condenser mist cavity, and the electrical box mist outlet 122 is communicated with the electrical box mist cavity.

[0071] When the condenser 4 needs to be cooled, the mist in the condenser mist chamber will be output from the condenser mist outlet 121 to the outdoor, and then circulated and dispersed to the condenser 4 through the negative pressure generated by the rotation of the outdoor axial flow fan blade, and then blown to the outdoor after evaporative heat absorption, so as to reduce the temperature of the condenser 4, thereby effectively solving the problem of excessive outdoor load under high temperature working conditions. When the electrical box 5 needs to be cooled, the mist in the electrical box mist chamber will be output from the electrical box mist outlet 122 to the mist outlet pipeline 7, and then output to the electrical box 5 through the mist outlet pipeline 7 to evaporate and absorb heat, so as to reduce the temperature of the components in the electrical box 5.

[0072] The arrangement of the mist dividing member 152 effectively divides the mist chamber 151 into two independent parts, ensuring that the mist supplied to the condenser 4 and the electrical box 5 does not interfere with each other. This not only improves the cooling effect, but also enhances the overall performance and stability of the equipment.

[0073] Specifically, the mist dividing member 152 is a mist dividing baffle, the mist chamber shell 15 includes a top cover 153 and a bottom shell 154, the mist dividing baffle is arranged on one of the top cover 153 and the bottom shell 154, and the other one is provided with a assembly clamping groove 155, the height of the mist dividing baffle is equal to the height from the plane of the top cover 153 to the plane of the bottom shell 154, and when the mist dividing baffle is inserted into the assembly clamping groove 155, the mist chamber 151 is divided into a condenser mist chamber and an electrical box mist chamber.

[0074] The height of the mist dividing baffle is equal to the height from the plane of the top cover 153 to the plane of the bottom shell 154, which enables the mist dividing baffle to closely fit inside the mist chamber shell 15, avoiding mist leakage. At the same time, the design of the assembly clamping groove 155 enables the mist dividing baffle to be firmly fixed on the mist chamber shell 15, improving the stability and durability of the structure.

[0075] Preferably, the mist dividing baffle is designed in one piece with the top cover 153, or the mist dividing baffle is designed in one piece with the bottom shell 154.

[0076] The one-piece design can enhance the structural strength of the entire mist chamber shell 15. The one-piece design also simplifies the manufacturing process, reduces the number of assembly steps and required parts. This helps to improve production efficiency, reduce costs, and reduce the failure rate caused by assembly errors.

[0077] Further, the bottom shell 154 is provided with a mist inlet 1541 to facilitate the introduction of mist generated by the atomizing assembly 3 into the mist chamber 151. The mist inlet 1541 is a cylindrical hole structure extending downward from the bottom shell 154, and its depth can be set to 8-10 mm.

[0078] Preferably, the mist inlet 1541 is designed in one piece with the bottom shell 154. The one-piece design can enhance the structural strength of the entire bottom shell 154.

[0079] In this embodiment, the condenser mist outlet 121 and the electrical box mist outlet 122 are respectively provided with a condenser regulating valve 1211 and an electrical box regulating valve 1221.

[0080] The condenser regulating valve 1211 is installed at the condenser mist outlet 121 for regulating and controlling the flow of mist to the condenser 4. The regulating valve can adjust the opening of the valve according to actual needs, manually or automatically, to achieve precise control of the mist flow. This design helps to ensure that the mist to the condenser 4 can be output according to the temperature of the condenser 4. The electrical box regulating valve 1221 is similar to the condenser regulating valve 1211, and can control the opening to regulate the flow of mist to the electrical box 5 according to the temperature of the electrical box 5.

[0081] In this embodiment, the mist outlet pipeline 7 is made of plastic or sponge with good heat preservation performance. Both materials have good heat preservation performance, which can effectively reduce the heat loss of the mist during transportation, thereby ensuring that the mist maintains stable temperature and state during transportation.

[0082] Please refer to Figure 3 , the embodiment also provides a multifunctional heat dissipation system, comprising: a chassis 8, a condenser 4, an electrical box 5 and the multifunctional heat dissipation device of the above embodiment, the chassis 8 is provided with a water storage groove 81, the water inlet 11 is arranged corresponding to the water storage groove 81, and the mist outlet 12 is arranged corresponding to the condenser 4 and the electrical box 5.

[0083] When the water pumping assembly 2 is started, the condensate water (i.e. atomizing liquid) in the water storage groove 81 enters the water storage chamber 131 through the water inlet 11, and the condensate water is extracted from the water storage chamber 131. The extracted condensate water is transported to the atomizing cavity 14 through the pipeline. The atomizing assembly 3 converts the condensate water into fine mist droplets. The mist enters the condenser mist chamber and the electrical box mist chamber respectively. The mist in the condenser mist chamber is discharged through the condenser mist outlet 121, covering the condenser 4 for evaporative cooling. The mist in the electrical box mist chamber is discharged through the electrical box mist outlet 122, transported to the electrical box 5 through the mist outlet pipeline 7, and subjected to evaporative cooling.

[0084] In this embodiment, the multifunctional heat dissipation device is arranged on the chassis 8, effectively utilizing outdoor condensate water and improving the utilization rate of condensate water. At the same time, the system replaces the outdoor axial flow fan blade water circle structure, optimizes the fan blade structure, reduces mechanical friction and air turbulence, eliminates the noise generated by the water, solves the problem of poor noise experience. In addition, the system also replaces the traditional heat dissipation fin structure, has higher heat dissipation efficiency, and the electrical box 5 structure is more compact, which can promote miniaturization design.

[0085] The water storage groove 81 is the lowest point of the water level of the base plate 8 and has a certain depth, which can be set to 10-15 mm, for collecting the condensate water on the outdoor side.

[0086] By setting the water storage groove 81 at the lowest point of the base plate 8, it can be ensured that all the condensate water generated from the outdoor side can flow naturally and collect here. This design avoids the disordered diffusion of condensate water on the base plate 8, reducing the risk of water stains and water accumulation. The water storage groove 81 has a certain depth (such as 10-15 mm), which is sufficient to contain a certain amount of condensate water, thereby preventing water from overflowing the base plate 8 and further avoiding water from seeping into the building interior or causing other damage.

[0087] In this embodiment, the liquid level detection device 82 is arranged at the position of the water storage groove 81 of the base plate 8. The liquid level detection device 82 is used to detect the liquid level of the condensate water in the water storage groove 81. When the liquid level detection device 82 detects that the liquid level of the condensate water is less than a predetermined liquid level, the system controls the water pumping assembly 2 to pump the condensate water from the water storage chamber 131.

[0088] In this embodiment, the water inlet 11 is arranged corresponding to the water storage groove 81 and has a certain distance from the bottom of the water storage groove 81. Specifically, the distance between the water inlet 11 and the bottom of the water storage groove 81 can be set to 5-8 mm.

[0089] The distance between the water inlet 11 and the bottom of the water storage groove 81 is 5-8 mm, which effectively prevents the deposition of sediment and impurities into the system and reduces the risk of pipe blockage. By avoiding the deposition of sediment into the system, the stability and reliability of the system are improved, and the frequency and cost of maintenance are reduced.

[0090] In this embodiment, please refer to Figure 6 , a shielding cover 51 is arranged in the electrical box 5 to separate the control mainboard 52 in the electrical box 5 from the atomized liquid after atomization.

[0091] The atomized liquid, whether it is water mist or mist of other chemicals, may contain certain corrosive or conductive properties. The presence of the shielding cover 51 can effectively isolate these atomized liquids, preventing them from directly contacting the control mainboard 52, thereby avoiding the risk of short circuit, corrosion or damage to the mainboard. This can ensure the normal operation of the electrical box 5 and prolong its service life.

[0092] The shielding cover 51 is made of metal or plastic with good thermal conductivity.

[0093] Metal or plastic not only has good thermal conductivity, which can quickly conduct the heat generated by the control mainboard 52, helping to dissipate heat and control temperature in the system, but also has high strength and corrosion resistance, which can effectively resist the erosion of atomized liquid, ensuring the stability and reliability of long-term use.

[0094] In this embodiment, a plurality of air outlet grilles 53 are provided on the electrical box 5 , and the width of the air outlet grilles 53 can be set to 3-5 mm. After absorbing the heat of the components, the mist vaporizes and is discharged through the air outlet grilles 53 , thereby taking away the heat generated in the electrical box 5 .

[0095] See also Figure 7 and Figure 8 This embodiment also provides a control method for a multifunctional heat dissipation system, including:

[0096] S101: determining whether the instruction is a cooling instruction based on a user instruction;

[0097] If the instruction is a cooling instruction, step S102 is executed; if the instruction is not a cooling instruction, step S105 is executed.

[0098] S102: Determine whether the temperature of the condenser or the electrical box reaches a corresponding predetermined temperature;

[0099] S103: If the temperature of the condenser or the electrical box reaches a corresponding predetermined temperature, controlling the multifunctional heat dissipation device to start a misting mode;

[0100] S104: If the temperatures of the condenser and the electrical box do not reach the corresponding predetermined temperatures, controlling the multifunctional heat dissipation device to not start the atomization mode;

[0101] S105: Control the multi-functional heat dissipation device to not start the atomization mode.

[0102] This embodiment monitors the temperature of the condenser and electrical box in real time and activates the atomization mode promptly when the temperature reaches a predetermined value. This process ensures that the heat dissipation device functions when it is most needed, thereby improving heat dissipation efficiency. This helps protect electrical equipment from overheating and prolongs its service life.

[0103] In some embodiments, when the user turns on the machine, it is detected whether the current mode is the cooling mode;

[0104] If the current mode is cooling mode, the current outdoor ambient temperature T is detected in real time. Then, it is determined whether the current outdoor ambient temperature T is less than or equal to the preset ambient upper limit temperature T1, and whether the current outdoor ambient temperature T is greater than or equal to the preset ambient lower limit temperature T0.

[0105] If the current outdoor ambient temperature T is less than the preset lower limit temperature T0, it means that the outdoor temperature is low and the operating temperature of the whole machine will not rise too high, so there is no need to turn on the mist cooling.

[0106] If the preset environment lower limit temperature T0≤ the current outdoor environment temperature T≤ the preset environment upper limit temperature T1, it indicates that the outdoor temperature is in the normal operation range, and the atomization is not needed to be started in the initial stage of the operation, and whether the atomization is started can be determined according to the temperature of the outer tube and the mainboard in the operation process.

[0107] Whether the atomization is started according to the temperature of the outer tube and the mainboard in the operation process specifically includes: detecting the outer tube temperature T 外管 and the mainboard temperature T 主板 of the controller in real time, then judging whether the outer tube temperature T 外管 is ≤T2 (T2 represents a target threshold value of the outer tube temperature, which can be specifically set to 50-60℃), and judging whether the mainboard temperature T 主板 of the controller is ≤T3 (T3 represents a target threshold value of the mainboard temperature, which can be specifically set to 55-65℃). Generally, after the operation is started, the outdoor tube temperature rises faster, while the mainboard temperature of the controller rises slowly, and it will gradually rise to a stable value in about half an hour, so whether the atomizer is started is determined by the size of the outdoor tube temperature after the operation is started, which is convenient for timely response. If T 外管 ≤T2, it indicates that the operation load of the whole machine is normal, and the atomization does not need to be started, so the atomizer does not start the atomization mode; if T 外管 >T2, it indicates that the load is too heavy, and the atomization needs to be started for heat dissipation, wherein the condenser adjusting valve 1211 (i.e. the atomization adjusting valve 1 and the adjusting valve 1 in Figure 8 ) adjusts the opening degree according to the control function f(P1) to control the amount of mist output to the condenser. If the mainboard temperature T 主板 of the controller is ≤T3, it indicates that the mainboard temperature is normal, and the temperature does not need to be lowered, at this time, the electric appliance box adjusting valve 1221 (i.e. the adjusting valve 2 and the atomization adjusting valve 2 in Figure 8 ) has an opening degree of 0, then the mainboard temperature T 主板 of the controller is detected in real time; if the mainboard temperature T 主板 of the controller is >T3, it indicates that the mainboard temperature is high, and the temperature needs to be lowered, at this time, the electric appliance box adjusting valve 1221 for heat dissipation of the electric appliance box adjusts the opening degree according to the control function f(P2) to control the amount of mist output to the electric appliance box.

[0108] Wherein, f(P1)=k1w(T)·T+k2w(T 外管 )·T 外管 +k3ΔT+k4ΔT 外管 +P0

[0109] ΔT=T(t)-T(t-1)

[0110] ΔT 外管 =T 外管 (t)-T 外管 ​​(t-1)

[0111] f(P2) = k1w(T) · T + k5w(T 主板 ) · T 主板 + k3ΔT + k6ΔT 主板 + P0

[0112] ΔT 主板 = T 主板 (t) - T 主板 (t-1)

[0113] In the formula:

[0114] k1, k2, k5 respectively represent the proportional coefficient of the current outdoor environment temperature T, the outer pipe temperature T 外管 and the controller mainboard temperature T 主板 , which is set based on actual experimental data or system requirements;

[0115] w(T), w(T 外管 ), w(T 主板 ) respectively represent the weight function of the current outdoor environment temperature T, the outer pipe temperature T 外管 and the controller mainboard temperature T 主板 , which can be selected with different weight coefficients in different temperature ranges;

[0116] ΔT, ΔT 外管 , ΔT 主板 respectively represent the change rate of the current outdoor environment temperature T, the outer pipe temperature T 外管 and the controller mainboard temperature T 主板 , which uses the difference between the current temperature and the previous time, which can be set to an interval of 1 min;

[0117] k3, k4, k6 respectively represent the proportional coefficient of ΔT, ΔT 外管 , ΔT 主板 temperature change rate, which is set based on actual experimental data or system requirements;

[0118] P0 represents the initial opening degree of the atomization regulating valve;

[0119] T ( t ) represents the current outdoor environment temperature detected at time t; T ( t-1 ) represents the current outdoor environment temperature detected at time t-1; T 外管 (t) represents the outer pipe temperature detected at time t; T 外管 (t-1) represents the outer pipe temperature detected at time t-1; T 主板 (t) represents the controller mainboard temperature detected at time t; T 主板(t-1) represents the controller mainboard temperature detected at time t-1.

[0120] If the current outdoor environment temperature T > preset environment upper limit temperature T1, it indicates that the outdoor temperature is too high, and the atomizer (i.e., the multifunctional heat dissipation device) defaults to directly start the atomization mode to dissipate heat for the condenser and the electrical box, so as to reduce the start-up operation load and avoid sharp increase of the temperature rise of the components. At this time, the condenser regulating valve 1211 and the electrical box regulating valve 1221 are defaulted to be adjusted to the maximum opening.

[0121] After the condenser regulating valve 1211 and the electrical box regulating valve 1221 are adjusted to the maximum opening and continue for a predetermined time (for example, the predetermined time can be set to 10 min), the condenser regulating valve 1211 adjusts the opening control output to the amount of mist output to the condenser according to the control function f(P1), and judges whether the controller mainboard temperature T 主板 ≤ T3, and then performs subsequent operations according to the judgment result.

[0122] In this embodiment, the opening of the regulating valve is adjusted in real time according to multiple real-time variables (such as temperature, load state, etc.), so as to control the output amount of mist, which can avoid the hysteresis effect and reduce the inaccuracy of single factor control. At the same time, a regulating function is introduced, which combines the temperature range weight and the temperature change rate to improve the control accuracy. In this way, the system can realize dynamic adjustment of temperature control, thereby improving the stability and reliability of the entire system.

[0123] Through the above method, the system can adapt to different scenes and working conditions. Whether in high-temperature or low-temperature environment, or in different load states, the system can automatically adjust the opening of the regulating valve to meet the actual demand. This flexibility enables the system to maintain high efficiency in various complex environments.

[0124] At the same time, the system can reduce unnecessary consumption of condensed water by precisely controlling the opening of the atomization device. This means that the system can be more energy-efficient during operation, improving energy utilization efficiency.

[0125] In some embodiments, the water replenishment records of the equipment in the past period of time are collected and analyzed, including the water replenishment time, water replenishment speed, water replenishment amount, and the environmental conditions (such as temperature and humidity) at that time. Through data analysis, the correlation between water replenishment demand and environmental conditions is identified, such as increased water replenishment demand in high-temperature and low-humidity environment, and reduced water replenishment demand in low-temperature and high-humidity environment. The temperature and humidity of the environment where the equipment is located are monitored in real time. The real-time data are compared with the historical data to predict the current water replenishment demand.

[0126] In some embodiments, when the water replenishment system appears abnormal or fails, the system should be able to automatically issue a warning signal and prompt the user to take corresponding measures.

[0127] For example, when the water level sensor fails or the water replenishing port is blocked, the system should be able to automatically close the water replenishing function and notify the user to check and repair.

[0128] The embodiment also provides an air conditioner comprising the multifunctional heat dissipation system.
