Description

Technical Field

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

[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 under high ambient temperature conditions. As a key device for regulating indoor temperature, the performance of air conditioners directly affects the user's comfort and quality of life. However, under high temperature conditions, the operation of air conditioners faces a series of challenges.

[0003] On the one hand, in order to ensure the cooling effect of the air conditioner, users expect the compressor to maintain a high operating frequency. However, the increase in the compressor frequency will cause the temperature rise of its internal and surrounding components to exceed the standard, which will not only affect the life of the components, but may also trigger the protection mechanism, causing the compressor to reduce the frequency of operation, thereby reducing the cooling 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, its design needs to achieve efficient cooling effect under limited heat dissipation conditions, which is itself a complex and difficult problem.

[0004] In order to meet these challenges, existing integrated air conditioners use a variety of heat dissipation methods. For example, axial flow blades are used to spray water onto the condenser, and the evaporation of water absorbs heat to reduce the temperature of the condenser, thereby reducing the load on the outdoor unit. At the same time, heat sinks are usually installed on the electrical box to increase the heat exchange area between components and air and improve heat dissipation efficiency. Under normal working conditions, these measures can maintain the normal operation of the compressor frequency and ensure the cooling effect of the air conditioner.

[0005] However, when the outdoor temperature is extremely high, the effect of these heat dissipation methods becomes insufficient. Since the electrical box usually adopts a sealed structure, the heat taken away by the outdoor air through the heat sink is limited, and the temperature of the components cannot be effectively reduced. In order to avoid excessive temperature rise of the components, the compressor frequency has to be adjusted down to a lower level, which directly leads to a decrease in cooling capacity and cannot meet the cooling needs of users. At the same time, the effect of outdoor water evaporation and heat absorption is also limited, and the load of the outdoor unit cannot be effectively reduced, which further limits the increase in the compressor frequency.

[0006] In order to solve this problem, patent number CN114144030A proposes a new heat dissipation device and its control method. The device connects the heat dissipation pipe with the refrigerant circuit in the air-conditioning unit by setting a heat sink and a heat dissipation pipe, so that the low-temperature refrigerant circulates in the heat dissipation pipe and exchanges heat with the heat sink, thereby reducing the surface temperature of the components. This solution improves the heat dissipation effect to a certain extent and effectively dissipates the heat of the variable frequency electrical box. However, this method also has certain disadvantages, that is, directly using the refrigerant for heat dissipation will lose a part of the cold capacity, which will have an adverse effect on the overall cooling effect of the air conditioner. Summary of the invention

[0045] See also Figure 1-3 The present embodiment provides a multifunctional heat dissipation device, comprising: a shell 1, a water pumping component 2 and an atomizing component 3. The shell 1 is provided with a water inlet 11 and a mist outlet 12 for conveying mist toward the condenser 4 and the electrical box 5. The water pumping component 2 and the atomizing component 3 are installed in the shell 1. One end of the water pumping component 2 is arranged corresponding to the water inlet 11, and the other end of the water pumping component 2 is arranged corresponding to the input port of the atomizing component 3. The output port of the atomizing component 3 is arranged corresponding to the mist outlet 12, so that the water pumping component 2 draws the atomized liquid from the water inlet 11 and conveys it to the atomizing component 3 for atomization, and discharges it from the mist outlet 12.

[0046] When the pumping assembly 2 is started, it will suck the atomized liquid from the water inlet 11 and transport it to the atomizing assembly 3. In the atomizing assembly 3, the liquid is converted into fine droplets. The formed droplets are discharged through the mist outlet 12 and guided to the vicinity of the condenser 4 and the electrical box 5. After the droplets contact the surfaces of these heat sources, they evaporate quickly, absorb a large amount of heat, and reduce their temperature.

[0047] This embodiment effectively increases the contact area and improves the evaporation heat absorption efficiency by transporting the micron-sized particles generated by atomization to the electrical box 5 and the condenser 4, which can quickly reduce the temperature of the target area, thereby effectively solving the problems of heat dissipation difficulty of the electrical box 5 and excessive outdoor load under high temperature conditions.

[0048] In this embodiment, please refer to Figure 1-4 The shell 1 includes: a water storage chamber shell 13, an atomization chamber shell 14 and a mist chamber shell 15 which are connected in sequence, a water inlet 11 is arranged on the water storage chamber shell 13, a water storage chamber 131 connected with the water inlet 11 is arranged in the water storage chamber shell 13, a water pumping component 2 is installed in the water storage chamber 131, an atomization chamber 141 is arranged in the atomization chamber shell 14, an atomization component 3 is installed in the atomization chamber 141, a mist outlet 12 is arranged on the mist chamber shell 15, a mist chamber 151 connected with the mist outlet 12 is arranged in the mist chamber shell 15, and the water storage chamber 131, the atomization chamber 141 and the mist chamber 151 are connected in sequence.

[0049] The water storage chamber shell 13 is used to store water to be atomized. The water storage chamber 131 is equipped with a pumping assembly 2, which can extract water from the water inlet 11 and send it to the next stage. The atomization chamber shell 14 has a built-in atomization assembly 3, which converts the water sent from the water storage chamber 131 into fine droplets. This process can be completed by ultrasonic vibration, high-pressure nozzles, etc. The mist chamber shell 15 is used to collect and temporarily store the atomized water vapor. The mist is directed to the condenser 4 and the electrical box 5 and other areas that need to be cooled through the mist outlet 12.

[0050] In this embodiment, a water filling port 132 (such as Figure 2 As shown), the water replenishment port 132 is connected to the water storage chamber 131.

[0051] The design of the water supply port 132 enables the system to continuously obtain sufficient water, ensuring a long-term atomization cooling effect. At the same time, it avoids system interruption due to water shortage and improves the reliability and stability of the air conditioner in a high temperature environment. In addition, a 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 replenishment port 132 can be connected to an external water replenishment tank or a water replenishment pipe (not shown in the figure).

[0053] When choosing to use a water replenishment tank, the user can place the water replenishment tank at a suitable location near the air conditioner. The water replenishment tank usually has a water outlet, which is connected to the water replenishment 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 unimpeded water flow. During the connection process, the user only needs to insert one end of the hose or pipe into the water outlet of the water replenishment tank, connect the other end to the water replenishment port 132, and tighten the connecting nut or buckle to complete the connection of the water replenishment tank.

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

[0055] In this embodiment, a filtering structure 133 (such as Figure 2 shown).

[0056] The filter structure 133 can ensure that all water sources flowing into the water storage chamber shell 13 through the water inlet 11 must first pass through the filter structure 133. This design is intended to effectively intercept and remove impurities, particles or other potential pollutants in the water, thereby preventing the atomizer assembly 3 from being blocked.

[0057] The filter structure 133 may be a filter net, or may be other filter structures 133 such as a filter element.

[0058] In this embodiment, a mounting groove 134 (such as Figure 2 As shown), used to fix the control module 6 (as Figure 2 As shown), the control module 6 is used to control the entire atomization assembly 3 to run according to a set program.

[0059] The design of the assembly groove 134 fully considers the installation convenience and stability 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 to avoid shaking or falling off during operation. At the same time, the edge of the assembly groove 134 adopts a smooth transition treatment, which not only protects the control module 6 from physical damage, but also facilitates the user to perform installation and removal operations.

[0060] In this embodiment, the pumping component 2 is a pumping wheel, and its pumping end is embedded in the water inlet 11 to facilitate contact with more condensed water and improve pumping efficiency. The water storage chamber 131 has a certain volume for storing the atomized liquid sucked up by the pumping wheel.

[0061] The pumping wheel rotates at high speed to form a low-pressure area in the water storage chamber 131 , and the external atmospheric pressure presses the atomized liquid into the water storage chamber 131 through the water inlet 11 .

[0062] The pumping assembly 2 may also be an electric pump and a magnetic pump, or other devices or structures capable of pumping the atomized liquid from the water inlet 11 into the water storage chamber 131 .

[0063] The pumping wheel draws the atomized liquid from the water inlet 11 for atomization. If the atomized liquid near the water inlet 11 is insufficient, the pumping wheel will draw the atomized liquid from the water storage chamber 131 for atomization. If the atomized liquid in the water storage chamber 131 is insufficient, the water replenishing port 132 will open and replenish the atomized liquid to the water storage chamber 131 to meet the entire heat dissipation process.

[0064] In this embodiment, please refer to Figure 5 The atomizing chamber shell 14 is provided with a water inlet 142 which is in communication with the atomizing chamber 141 , and the water inlet 142 is arranged corresponding to the input port of the atomizing assembly 3 .

[0065] By directly connecting the water inlet 142 with the input port of the atomizing assembly 3, the intermediate links are reduced, the risk of waterway blockage or leakage is reduced, and the stable operation of the system is ensured. The direct connection between the water inlet 142 and the atomizing 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 shell 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 shell 14 and the atomizing assembly 3 are positioned.

[0067] In the atomizing chamber shell 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 convex structure of suitable shape protruding from the inner wall or outer wall of the atomizing chamber shell 14. Then, in the atomizing chamber shell 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 edge of the positioning hole 31 is smoothed to reduce friction during assembly and ensure the accuracy of positioning.

[0068] During the assembly process, the atomizer assembly 3 is aligned with the atomizer chamber housing 14 so that the positioning hole 31 and the positioning member 143 are aligned with each other. Then, the atomizer assembly 3 is gently pushed so that the positioning member 143 is smoothly inserted into the positioning hole 31. Once the positioning member 143 completely enters the positioning hole 31, the tight fit between the two will effectively prevent the atomizer assembly 3 from moving relative to the atomizer chamber housing 14, thereby achieving accurate positioning and a stable connection between the two.

[0069] Among them, the atomization component 3 can be an ultrasonic atomizer component, a compression atomizer component, or a mesh atomizer component. Preferably, the atomization component 3 is an ultrasonic atomizer component, which uses 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 component is small in size and 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 pipeline 7 (such as Figure 3 As shown), one end of the mist outlet pipe 7 is connected to the mist outlet port 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 arranged in the mist chamber shell 15 to divide the mist chamber 151 into a condenser mist chamber and an electrical box mist chamber. The condenser mist outlet port 121 is connected to the condenser mist chamber, and the electrical box mist outlet port 122 is connected to the electrical box mist chamber.

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

[0072] The mist dividing element 152 effectively divides the mist chamber 151 into two independent parts, ensuring that the mist delivered to the condenser 4 and the electrical box 5 will not interfere with each other. This not only improves the heat dissipation effect, but also enhances the overall performance and stability of the device.

[0073] Specifically, the mist dividing element 152 is a mist dividing baffle, and 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 an assembly slot 155 is arranged on the other. 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. When the mist dividing baffle is inserted into the assembly slot 155, the mist chamber 151 is divided into a condenser mist chamber and an electrical box mist chamber.

[0074] The height of the mist baffle is equal to the height from the plane of the top cover 153 to the plane of the bottom shell 154. This design enables the mist baffle to fit tightly inside the mist chamber shell 15, thereby preventing mist leakage. At the same time, the design of the assembly slot 155 enables the mist baffle to be firmly fixed on the mist chamber shell 15, thereby improving the stability and durability of the structure.

[0075] Preferably, the mist baffle and the top cover 153 are designed as an integrated whole; or, the mist baffle and the bottom shell 154 are designed as an integrated whole.

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

[0077] Furthermore, the bottom shell 154 is provided with a mist inlet 1541 to facilitate the introduction of the mist generated by the atomization assembly 3 into the mist chamber 151. The mist inlet 1541 is a cylindrical perforated 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 integrated with the bottom shell 154. The integrated 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, and is used to adjust and control the flow of the mist delivered to the condenser 4. The regulating valve can adjust the opening of the valve manually or automatically according to actual needs, so as to achieve precise control of the mist flow. This design helps to ensure that the mist delivered 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 according to the temperature of the electrical box 5 to adjust the flow of the mist delivered to the electrical box 5.

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

[0082] See also Figure 3 The present embodiment further provides a multifunctional heat dissipation system, including: a chassis 8, a condenser 4, an electrical box 5 and the multifunctional heat dissipation device of the above embodiment, wherein a water storage groove 81 is provided on the chassis 8, the water inlet 11 is provided corresponding to the water storage groove 81, and the mist outlet 12 is provided corresponding to the condenser 4 and the electrical box 5.

[0083] When the pumping component 2 is started, the condensed water (i.e., atomized liquid) in the water storage groove 81 enters the water storage chamber 131 through the water inlet 11, and the condensed water is extracted from the water storage chamber 131. The extracted condensed water is transported to the atomization chamber shell 14 through a pipeline. The atomization component 3 converts the condensed water into fine 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, and is transported to the electrical box 5 through the mist outlet pipeline 7 for evaporative cooling.

[0084] This embodiment effectively utilizes outdoor condensed water by setting a multifunctional heat dissipation device on the chassis 8, thereby improving the utilization rate of condensed water. At the same time, this system replaces the outdoor axial flow fan water ring structure, optimizes the fan blade structure, reduces mechanical friction and air turbulence, and eliminates the noise generated by water beating, solving the problem of poor noise experience. In addition, this system also replaces the traditional heat sink structure, has higher heat dissipation efficiency, and the electrical box 5 has a more compact structure, which can promote miniaturization design.

[0085] The water storage groove 81 is the lowest point of the water level of the chassis 8 and has a certain depth. The specific depth can be set to 10-15 mm and is used to collect condensed water on the outdoor side.

[0086] By setting the water storage groove 81 at the lowest point of the chassis 8, it can be ensured that all condensed water generated from the outdoor side can naturally flow to and gather there. This design prevents the condensed water from spreading disorderly on the chassis 8, reducing the risk of water stains and water accumulation. The water storage groove 81 has a certain depth (such as 10-15mm), which is sufficient to accommodate a certain amount of condensed water, thereby preventing water from overflowing the chassis 8, and further preventing water from penetrating into the building or causing other damage.

[0087] In this embodiment, the bottom plate 8 is provided with a liquid level detection device 82 at the position of the water storage groove 81. The liquid level detection device 82 is used to detect the liquid level of the condensed water in the water storage groove 81. When the liquid level detection device 82 detects that the liquid level of the condensed water is less than the predetermined liquid level, the system controls the pumping assembly 2 to pump the condensed 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 water inlet 11 is kept 5-8 mm away from the bottom of the water storage groove 81, effectively preventing bottom sediments and impurities from entering the system and reducing the risk of pipe blockage. By preventing sediments from entering the system, the stability and reliability of the system are improved, and the maintenance frequency and maintenance cost are reduced.

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

[0091] The atomized liquid, whether water mist or mist of other chemicals, may contain certain corrosiveness or conductivity. The shielding cover 51 can effectively isolate the atomized liquid and prevent it 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 extend 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, can quickly conduct the heat generated by the control mainboard 52, which is helpful for the heat dissipation and temperature control of the system, but also has high strength and corrosion resistance, can effectively resist the erosion of the atomized liquid, and ensure 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 the instruction of the user;

[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 temperature of the condenser and the electrical box does not reach the corresponding predetermined temperature, controlling the multifunctional heat dissipation device not to start the atomization mode;

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

[0102] This embodiment monitors the temperature of the condenser and the electrical box in real time and starts the atomization mode in time when the temperature reaches a predetermined value. This process can ensure that the heat dissipation device works when it is most needed, thereby improving the heat dissipation efficiency. This helps to protect electrical equipment from overheating damage and extend 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 relatively low, the temperature rise of the whole machine will not be too high, and there is no need to turn on the mist cooling.

[0106] If the preset environment lower limit temperature T0 ≤ current outdoor environment temperature T ≤ preset environment upper limit temperature T1, it means that the outdoor temperature is within the normal operating range. There is no need to turn on the mist cooling in the initial stage of startup operation. Whether to turn on the mist can be determined based on the temperature of the external tube and the mainboard during operation.

[0107] Determine whether to start atomization based on the temperature of the outer tube and the mainboard during operation. Specifically include: Real-time detection of the outer tube temperature T 外管 And controller mainboard temperature T 主板 Then determine the outer tube temperature T 外管 Is it ≤T2 (T2 represents a target threshold of the external tube temperature, which can be set to 50-60℃), and judge the controller mainboard temperature T 主板 Is it ≤T3 (T3 indicates a target threshold of the motherboard temperature, which can be set to 55-65℃). Generally speaking, after the machine is turned on, the outdoor pipe temperature rises faster, while the controller motherboard temperature rises slowly, and it normally takes about half an hour to gradually rise to a stable value. Therefore, after the machine is turned on, the outdoor pipe temperature can be used to determine whether the atomizer is turned on, so as to facilitate timely response. 外管 ≤T2, indicating that the whole machine is running normally, and there is no need to turn on atomization, so the atomizer does not start the atomization mode; if T 外管 >T2, indicating that the load is too heavy and atomization needs to be turned on for heat dissipation. The condenser regulating valve 1211 (i.e. Figure 8 The atomizing regulating valve 1 and regulating valve 1) in the control function f(P1) adjust the opening to control the amount of mist output to the condenser. 主板 ≤T3, indicating that the mainboard temperature is normal and no cooling is required. At this time, the electrical box regulating valve 1221 (i.e. Figure 8 The opening of the regulating valve 2 and the atomizing regulating valve 2) is 0, and then the temperature T of the controller mainboard is detected in real time. 主板 ; If the controller motherboard temperature T 主板 >T3, indicating that the temperature of the mainboard is high and needs to be cooled. At this time, the electrical box regulating valve 1221 used for heat dissipation of the electrical box adjusts the opening according to the control function f(P2) to control the amount of mist output to the electrical box.

[0108] Where, 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] Where:

[0114] k1, k2, k5 represent the current outdoor ambient temperature T, external pipe temperature T 外管 and controller motherboard temperature T 主板 The proportionality factor is set based on actual experimental data or system requirements;

[0115] w(T), w(T 外管 )、w(T 主板 ) represent the current outdoor ambient temperature T, external pipe temperature T 外管 and controller motherboard temperature T 主板 The weight function can select different weight coefficients in different temperature ranges;

[0116] ΔT, ΔT 外管 , ΔT 主板 Respectively represent the current outdoor ambient temperature T and external pipe temperature T 外管 and controller motherboard temperature T 主板 The rate of change uses the difference between the current temperature and the previous moment, which can be set to an interval of 1 minute;

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

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

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

[0120] If the current outdoor ambient temperature T> the preset ambient upper limit temperature T1, it means that the outdoor temperature is too high, and the atomizer (i.e., the multifunctional heat dissipation device) directly turns on the atomization mode by default to dissipate heat from the condenser and the electrical box, so as to reduce the startup load and avoid a sharp increase in the temperature of components. At this time, the condenser regulating valve 1211 and the electrical box regulating valve 1221 are adjusted to the maximum opening by default.

[0121] When the condenser regulating valve 1211 and the electrical box regulating valve 1221 are adjusted to the maximum opening and last for a predetermined time (for example, the predetermined time can be set to 10 minutes), the condenser regulating valve 1211 adjusts the opening according to the control function f(P1) to control the amount of mist output to the condenser, and determines the controller mainboard temperature T 主板 Whether ≤T3, then perform subsequent operations based on the judgment result.

[0122] This embodiment timely adjusts the opening of the regulating valve according to multiple real-time variables (such as temperature, load status, etc.) to control the output mist volume, which can avoid the hysteresis effect and reduce the inaccuracy of single factor control. At the same time, a regulation 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 scenarios and working conditions. Whether in high or low temperature environments, or under different load conditions, the system can automatically adjust the opening of the regulating valve to meet actual needs. This flexibility enables the system to maintain efficient operation 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 atomizing device, which means that the system can save more energy and improve energy efficiency during operation.

[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 at that time (such as temperature and humidity). Through data analysis, the correlation between the water replenishment demand and the environmental conditions is identified, such as the water replenishment demand increases in a high temperature and low humidity environment, and the water replenishment demand decreases in a 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 is compared with the historical data to predict the current water replenishment demand.

[0126] In some embodiments, when an abnormality or failure occurs in the water replenishment system, the system should be able to automatically send out an early warning signal and prompt the user to take appropriate measures.

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