[0028] In this embodiment, a method for determining the operating parameters of an air conditioner running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Purifying air conditioners are generally equipped with pollutant detection devices and corresponding pollutant purification devices. The pollutant detection device detects the concentration of pollutants and determines whether purification is needed. Finally, the pollutant purification device purifies the room.

[0030] Existing pollutant purification devices generally include ultraviolet (UVC), high-efficiency air filters (HEPA), ion purification, and high temperature. UVC is harmful to the human body, HEPA filters require regular replacement, ion purification requires an external discharge device, and high-temperature sterilization solutions can only treat the evaporator surface. In short, existing solutions still have various shortcomings.

[0031] Wet dust removal is a traditional technology that uses water as a purification medium to remove pollutants. In recent years, many air conditioner manufacturers have also experimented with using water to purify filters or air inside air conditioners, such as Midea's dual water washing technology (water-washing filters) and Haier's centrifugal waterfall washing technology (water-washing air). However, these technologies still involve the issue of adding water and lack effective solutions for discharging polluted liquids after washing, limiting their widespread application.

[0032] In one embodiment, the air conditioner does not require any additional purification devices. Instead, it leverages its inherent humidity regulation advantages, using water vapor as a medium to improve the binding ability of indoor pollutants and water vapor by rationally adjusting the indoor temperature and humidity, thereby increasing sedimentation purification while improving the airflow tracking of pollutants. Furthermore, based on the type and concentration of pollutants, the optimal liquid film thickness on the heat exchanger surface is adjusted through dehumidification and condensation, allowing the air conditioner heat exchanger to maintain optimal pollutant enrichment and purification capabilities. Pollutants are ultimately concentrated on the evaporator and then discharged to the outside through condensed water. At the same time, the evaporator's self-cleaning function and high-temperature drying function are combined to further treat pollutants remaining on the evaporator. This effectively purifies indoor air by leveraging the advantages of the air conditioner without the need for other operations such as wastewater treatment, creating a smart and healthy living environment for consumers.

[0033] Indoor pollutants, especially microorganisms like bacteria and viruses, cannot exist independently in indoor air. They typically exist as aerosols or attached to carriers such as particulate matter. Particulate pollutants in indoor air can also serve as condensation nuclei for water vapor, causing it to condense into droplets, increasing their diameter (mass) and even causing them to settle. This is the principle behind wet dust removal. Furthermore, particulate matter and moisture in indoor air can also form aggregates due to surface tension and other factors. Therefore, moisture is a key carrier of indoor pollutants.

[0034] As a crucial component of air conditioners, heat exchangers are undoubtedly susceptible to dust accumulation. However, in essence, dust accumulation on the heat exchanger surface is actually the deposition of airborne particles onto the heat exchanger surface. While dust accumulation on the heat exchanger surface does lead to significant degradation of air conditioner performance, from another perspective, the heat exchanger is also a highly effective device for collecting and purifying dust and other particulate pollutants, acting as a high-efficiency filter like a HEPA filter. By optimizing the heat exchanger's pollutant collection capacity and addressing heat exchanger cleanliness issues, indoor air purification can be achieved.

[0035] The indoor unit of the air conditioner has an air inlet, an internal fan and an air outlet; an environmental parameter detection unit and an air quality detection unit are arranged in the air duct connected to the air inlet and the air outlet; the air conditioner also has a humidity adjustment unit.

[0036] The above environmental parameter detection unit is used to detect the indoor environmental temperature and humidity, and includes a temperature sensor, a humidity sensor, a temperature and humidity sensor, etc. The above air quality detection unit is used to detect the types and concentrations of indoor pollutants, and includes particulate pollutant detection sensors such as PM2.5 and PM0.3, gaseous pollutant detection sensors such as formaldehyde, VOC, and peculiar smell, and harmful microorganism concentration detection sensors such as bacteria and viruses, etc. The above humidity adjustment unit is used to adjust the indoor humidity, and includes a dehumidification module and an auxiliary humidification module realized by the air conditioner itself. The auxiliary humidification is realized by technologies such as a humidification water tank or fresh air humidification.

[0037] Figure 2 is a flowchart of a method for determining the operating parameters of an air conditioner according to an embodiment of the present application. As Figure 2 shown, the method includes the following steps:

[0038] Step S101, obtain the types of pollutants and the concentrations of the above pollutants in a predetermined space, and the pollutants in the above predetermined space are the pollutants in the air in the predetermined space where the indoor unit of the air conditioner is located;

[0039] Among them, the types of the above pollutants include particulate pollutants C such as PM2.5 and PM0.3, gaseous pollutant concentrations P such as formaldehyde, VOC, and peculiar smell, and harmful microorganism concentrations M such as bacteria and viruses, etc.

[0040] Judge whether purification is required according to the pollutant concentration situation. Specifically, when C < C0 and P < P0 and M < M0, it indicates that the indoor air is clean and air purification is not required, and the judgment is negative, and the air conditioner operates normally. The above normal operation means that the air conditioner executes common functions such as refrigeration and heating based on the user's instructions. Among them, C0 is the judgment standard value of the particulate pollutant concentration, preferably 0 < C0 ≤ 0.035mg / m 3 . P0 is the judgment standard value of the gaseous pollutant concentration, preferably 0 < P0 ≤ 0.03mg / m 3 . M0 is the judgment standard value of the microorganism pollutant concentration, preferably 0 < M0 ≤ 1000CFU / m 3 . When C0 ≥ C or P0 ≥ P or M0 ≥ M, it indicates that the indoor air is dirty and purification is required, and the judgment is positive, and the air conditioner operates in the purification mode and executes the next step.

[0041] In order to better achieve the self-cleaning effect, the above method also includes: adjusting the humidity in the above-mentioned predetermined space and the water vapor condensation diameter in the air in the above-mentioned predetermined space according to the type of the above-mentioned pollutants and the concentration of the above-mentioned pollutants, so that the humidity in the above-mentioned predetermined space is within a first preset range, and the above-mentioned water vapor condensation diameter is within a second preset range. Specifically, the temperature T and humidity RH in the above-mentioned predetermined space are mainly adjusted by the air conditioner itself. When the air conditioner adjustment cannot meet the humidity control requirements, an additional water tank or a fresh air humidification module is used to control the humidity. The temperature and humidity are related to the type of pollutant and the currently detected concentration, wherein the range of the temperature T in the above-mentioned predetermined space is: 20≤T≤30℃, the above-mentioned first preset range is 65%≤RH≤75%, and the above-mentioned second preset range is d<5um.

[0042] To ensure that the water vapor has a good entrainment capacity and that as many pollutants as possible are carried into the heat exchanger by the water vapor, the air conditioner is controlled to maintain the current environmental parameters for a certain period of time t1. The value of t1 is related to the current temperature, humidity, and pollutant concentration, and is preferably 5≤t1≤15min.

[0043] Step S103, obtaining the air volume of the indoor unit of the air conditioner;

[0044] The specific implementation steps of step S103 are as follows:

[0045] Step S1031, determining the wind speed of the indoor unit of the air conditioner according to the rotation speed of the indoor fan of the indoor unit of the air conditioner;

[0046] Step S1032: determining the air volume of the indoor unit of the air conditioner according to the wind speed of the indoor unit of the air conditioner.

[0047] The wind speed v of the air conditioner indoor unit is related to the air volume W of the air conditioner indoor unit and is controlled by the internal fan speed r of the air conditioner indoor unit, that is, v = f4(r). Preferably, the internal fan speed of the air conditioner indoor unit is the value that maximizes the product of the air conditioner filtration efficiency and the air volume of the air conditioner.

[0048] Step S105, determining the operating time of the air purification mode of the indoor unit of the air conditioner based on the type of the above-mentioned pollutants, the concentration of the above-mentioned pollutants and the air volume of the indoor unit of the above-mentioned air conditioner, wherein the removal rate of the above-mentioned pollutants is proportional to the operating time of the above-mentioned air purification mode, the removal rate of the above-mentioned pollutants is the amount of the above-mentioned pollutants removed per unit time, and the concentration of the above-mentioned pollutants is proportional to the operating time of the above-mentioned air purification mode.

[0049] The specific implementation steps of step S105 are as follows:

[0050] Step S1051, determining a condensate film thickness based at least on the type of the pollutant, wherein the condensate film thickness is the thickness of the condensate carrying the pollutant and adhering to the surface of the heat exchanger, the heat exchanger being installed in the indoor unit of the air conditioner;

[0051] The types of pollutants mentioned above include particle size distribution, water solubility of gaseous pollutants, and microbial species. Different pollutant types, due to differences in mass, shape, and size, have different filtration and deposition mechanisms on the heat exchanger, resulting in different condensate film thicknesses for optimal filtration. The optimal condensate film thickness for these different pollutants can be determined through experimental data, preferably with a value of <0.15 mm. For more specific information, refer to Table 1 for determining the optimal condensate film thickness.

[0052] Table 1. Relationship between pollutant type and optimal condensate film thickness

[0053]

[0054]

[0055] Exemplarily, the thickness of the condensate film is determined at least according to the type of the above-mentioned pollutants, including: in the case where the type of the above-mentioned pollutants is a particulate pollutant, according to the diameter of the above-mentioned particulate pollutant, a first preset thickness interval is determined, and then the tube temperature of the above-mentioned heat exchanger is adjusted by adjusting the compressor frequency of the above-mentioned air conditioner indoor unit, the opening of the electronic expansion valve of the above-mentioned air conditioner indoor unit and the number of revolutions of the internal fan of the above-mentioned air conditioner indoor unit, and the tube temperature of the above-mentioned heat exchanger is adjusted so that the thickness of the above-mentioned condensate film is within the above-mentioned first preset thickness interval; in the case where the type of the above-mentioned pollutants is a gaseous pollutant, according to the solubility of the above-mentioned gaseous pollutant, a second preset thickness interval is determined, and then the tube temperature of the above-mentioned air conditioner indoor unit is adjusted. The heat exchanger tube temperature is adjusted by adjusting the compressor frequency, the opening of the electronic expansion valve of the air conditioner indoor unit, and the speed of the internal fan of the air conditioner indoor unit. The condensate film thickness is kept within the second preset thickness range by adjusting the heat exchanger tube temperature. If the pollutant is a microbial pollutant, a third preset thickness range is determined based on the genus of the microbial pollutant. The heat exchanger tube temperature is then adjusted by adjusting the compressor frequency, the opening of the electronic expansion valve of the air conditioner indoor unit, and the speed of the internal fan of the air conditioner indoor unit. The condensate film thickness is kept within the third preset thickness range by adjusting the heat exchanger tube temperature. The first preset thickness range is [0.08, 0.20] mm, the second preset thickness range is [0.13, 0.25] mm, and the third preset thickness range is [0.05, 0.17] mm.

[0056] It should be noted that since the air volume of the air conditioner indoor unit is determined based on the speed of the indoor fan of the air conditioner indoor unit, the air volume of the air conditioner indoor unit changes accordingly when the speed of the indoor fan of the air conditioner indoor unit is adjusted. The air volume of the air conditioner indoor unit in step S105 is the air volume obtained after adjusting the speed of the indoor fan of the air conditioner indoor unit. Specifically, the optimal condensate film thickness is first determined based on the type and concentration of the pollutant. Then, the compressor frequency of the air conditioner indoor unit, the opening of the electronic expansion valve of the air conditioner indoor unit, and the speed of the indoor fan of the air conditioner indoor unit are adjusted to adjust the pipe temperature of the heat exchanger. By adjusting the pipe temperature of the heat exchanger, the condensate film thickness approaches the optimal condensate film thickness. Then, the filtration efficiency is determined based on the condensate film thickness. The air volume of the air conditioner indoor unit is determined based on the adjusted speed of the indoor fan of the air conditioner indoor unit. Finally, the operating time of the air purification mode of the air conditioner indoor unit is determined based on the pollutant concentration, the condensate film thickness, and the air volume of the air conditioner indoor unit. The best filtering effect can be achieved by adjusting various parameters so that the condensate film thickness approaches the optimal condensate film thickness.

[0057] After determining the optimal condensate film thickness based on the type and concentration of pollutants, adjust the air conditioner's operating parameters to make the actual condensate film thickness approach the optimal value. The specific steps are as follows:

[0058] Step S201, obtaining the temperature and humidity in the predetermined space;

[0059] Step S202: determining the saturation temperature of the indoor unit of the air conditioner according to the temperature and humidity in the predetermined space; wherein the determination is specifically made according to a standard psychrometric chart.

[0060] Step S203, determining the thickness of the condensate film according to the tube temperature of the heat exchanger and the saturation temperature of the air conditioner. w And the saturation temperature T of the indoor unit of the above air conditioner s The difference is adjusted and controlled, that is, δ=f2(T s -T w ). In particular, δ=k2(T s -T w ) a , k2 is a constant, which characterizes the speed of condensation of moist air on the surface of the heat exchanger driven by temperature difference.

[0061] According to the optimal condensation liquid film thickness, the various operating parameters of the above-mentioned air conditioner are adjusted to a more optimal state, that is, the number of revolutions of the internal fan of the above-mentioned air conditioner indoor unit is determined, and the wind speed and air volume of the above-mentioned air conditioner indoor unit are determined accordingly, thereby realizing a dynamic adjustment.

[0062] Step S1052 : Determine the filtration efficiency of the air conditioner indoor unit based on the condensate film thickness. Specifically, the filtration efficiency E is related to the condensate film thickness δ, i.e., E = f1(δ). Here, E = k1δ, where k1 is a constant representing the relationship between film thickness and filtration efficiency, which is affected by the type of pollutant.

[0063] Step S1053: determining the operating time of the air purification mode of the indoor unit of the air conditioner according to the filtering efficiency, the concentration of the pollutants and the air volume of the indoor unit of the air conditioner.

[0064] Determining the operating time of the air purification mode of the air conditioner indoor unit according to the filtration efficiency, the concentration of the pollutants, and the air volume of the air conditioner indoor unit includes:

[0065] A mapping relationship is constructed to represent the mapping relationship between the filtration efficiency, the concentration of the pollutants, the air volume of the air conditioner indoor unit, and the operating time of the purification mode. Specifically, the operating time t2 of the purification mode is related to the concentration C of the pollutants, the air volume W of the air conditioner indoor unit, and the filtration efficiency E(δ) at a corresponding liquid film thickness, that is, t2 = f3(C, W, E(δ)). In particular, t2 = k3C / WE(δ), where k3 is a constant.

[0066] The operation time of the purification mode is determined according to the mapping relationship, the filtration efficiency, the concentration of the pollutants and the air volume of the indoor unit of the air conditioner.

[0067] Specifically, under certain temperature and humidity conditions, the air conditioner's compressor frequency is controlled to p, the electronic expansion valve opening to y, and the internal fan speed to r. The purification mode is then continued for the specified operating time. During this time, pollutants in the air are concentrated on the heat exchanger during air circulation and discharged outdoors along with condensed water, purifying the indoor air. Furthermore, the air conditioner is controlled to execute an evaporator self-cleaning program to further thoroughly remove any remaining pollutants. This evaporator self-cleaning program includes common processes such as condensation, frosting, defrosting, and drying.

[0068] Among them, the specific process of purification mode is as follows Figure 3 As shown, after the air conditioner is powered on, it detects and determines the indoor pollutant concentration and determines whether purification is needed. The indoor environmental parameters (for example, humidity parameters) are adjusted based on the pollutant type and concentration. Then, the air conditioner purification parameters are determined based on the pollutant type and concentration. Finally, the air conditioner is controlled to run the purification mode according to the corresponding parameters. Finally, the purification mode is ended and the air conditioner operates normally.

[0069] In one example, Figure 4As shown, when the indoor environmental parameters meet the conditions (for example, the humidity parameters are high enough), the steps of adjusting the indoor environmental parameters and determining the air conditioner purification parameters can be omitted. The air conditioner can be directly controlled to run the purification mode according to the corresponding parameters, and finally the purification mode is ended and the air conditioner operates normally.

[0070] The method for determining the operating parameters of the air conditioner of the present application first obtains the type of pollutants in a predetermined space and the concentration of the pollutants, wherein the pollutants in the predetermined space are the pollutants in the air in the predetermined space where the air conditioner indoor unit is located; then obtains the air volume of the air conditioner indoor unit; finally, based on the type of pollutants, the concentration of the pollutants and the air volume of the air conditioner indoor unit, determines the operating time of the air purification mode of the air conditioner indoor unit, wherein the removal rate of the pollutants is proportional to the operating time of the air purification mode, the removal rate of the pollutants is the amount of pollutants removed per unit time, and the concentration of the pollutants is proportional to the operating time of the air purification mode. The present application adjusts the operating parameters of the air conditioner by the type and concentration of the pollutants, thereby realizing dynamic adjustment of the operating time of the purification mode of the air conditioner, and avoiding the problem of the air purification mode of the air conditioner having a fixed operating time, which is time-consuming and power-consuming.
