Description

Technical Field

[0002] In modern living and working environments, air conditioners have become indispensable equipment, providing people with comfortable temperature and humidity conditions. However, in closed spaces, due to daily activities such as cooking and pet raising, various odor substances often accumulate in the indoor air. These odors not only affect the comfort of residents, but may also become a medium for the growth of microorganisms such as bacteria and mold, posing a threat to indoor air quality.

[0003] Traditionally, in order to deal with this problem, people have adopted a variety of air purification methods, such as activated carbon filtration, plasma purification, etc. These methods can remove odor substances in the air to a certain extent, but each has significant limitations. Although activated carbon filtration can effectively absorb some odors, its adsorption capacity is limited, and the filter element needs to be replaced regularly, which is costly and inconvenient to maintain. Plasma purification technology decomposes odor molecules by ionizing air to produce charged particles, but this process may produce byproducts such as ozone, causing secondary pollution to indoor air quality, and its purification efficiency is also limited by the type and concentration of odor. Therefore, how to remove indoor odors efficiently and economically in a closed environment has become a key issue that needs to be solved in the development of air conditioner technology.

[0094] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0095] One of the core concepts of the embodiments of the present invention is to clean the indoor odor by real-time monitoring of the odor information in the air and combining the physical properties of air conditioning condensation and frosting processes.

[0096] Reference Figure 1 , shows a flow chart of steps of an embodiment of a control method for an air conditioner of the present invention, which may specifically include the following steps:

[0097] Step 101, obtaining environmental odor data;

[0098] Before using the air conditioner to remove odors, you must first capture the odor and decide whether to turn on the air conditioner to remove odors based on the concentration of odor molecules in the air;

[0099] In one example, the odor concentration in indoor air can be detected by a metal oxide semiconductor sensor (MOS) with a detection range of 0-100 ppm (Parts Per Million), a resolution of 0.1 ppm, and a response time of ≤30 s.

[0100] Metal oxide semiconductor sensors use the adsorption of the measured gas to change the conductivity of the semiconductor and stimulate the alarm circuit by comparing the current change. Because of its very sensitive response, it is widely used in the field of measuring gas concentration. PPM is the abbreviation of Parts Per Million, which means "parts per million". It is used to indicate the trace concentration or proportion of a substance in the total.

[0101] The technology for realizing indoor air odor concentration detection may also be gas chromatography-mass spectrometry technology and electronic nose technology, and the sensor used may also be other electrochemical sensors or photoionization detectors and other devices, which are not limited in the embodiments of the present invention.

[0102] Step 102, when the environmental odor data meets the preset condensation condition, lowering the temperature of the evaporator of the air conditioner to a preset condensation temperature so that water vapor in the air forms a water film on the fins of the evaporator;

[0103] When the odor concentration in the air reaches the threshold specified by the business, the air conditioner begins the odor removal process. The first step is to control the air conditioner to enter the condensation state, and use the physical properties of the condensation process to do preliminary treatment of the odor; at the same time, the condensation stage is also a preparation for the next core step of odor removal, frosting.

[0104] The condensation process of the air conditioner refers to the process in which, during the operation of the air conditioner, the water vapor in the air condenses when it contacts the surface of the evaporator, forming water droplets or a water film because the surface temperature of the evaporator is lower than the dew point temperature of the ambient air. After the water film is formed, the adsorption and dissolution capacity of the water film can be used to absorb and dissolve odorous gases in the air, thereby achieving the purpose of purifying the air.

[0105] Step 103, obtaining environmental data after the temperature of the evaporator is reduced to a preset condensation temperature;

[0106] The environmental data of the air conditioner when it enters the condensation stage is obtained, so as to determine when to enter the next stage according to the environmental data.

[0107] Step 104, when the environmental data meets the preset frosting condition, lowering the temperature of the evaporator to a preset frosting temperature so that the water film on the fin condenses into frost;

[0108] As the temperature drops, the water film condensed on the evaporator is frozen into a frost layer. The physical properties of the frost layer determine that it is a porous solid structure with a large surface area and roughness. When air flows through the frost layer, odorous substances are captured by the pores of the frost layer based on the intermolecular forces.

[0109] In one example, during the frosting process, the working gear of the fan can be increased to speed up the air flow through the frost layer, further improving the deodorization effect.

[0110] Step 105, obtaining air conditioner data after the temperature of the evaporator is reduced to a preset frosting temperature;

[0111] During the frosting stage, it is necessary to continuously obtain the data of the air conditioner to determine the frosting progress of the air conditioner so that defrosting can be performed at the appropriate time.

[0112] Step 106, when the air conditioner data in the frosting stage meets the preset defrosting condition, raising the temperature of the evaporator to a preset defrosting temperature so that the frost on the fins melts into condensed water and is discharged;

[0113] When the thickness of the frost layer reaches the preset threshold, the defrosting process is started, and the electric auxiliary heating is turned on to increase the temperature and melt the frost layer into condensed water.

[0114] Step 107, after the frost melts into condensed water and is discharged, the temperature of the evaporator is adjusted to a temperature set by the user.

[0115] After the frost layer melts, the condensed water is discharged, taking away the odor molecules to prevent secondary pollution. The frosting and defrosting process can also achieve self-cleaning of the air conditioner evaporator, further preventing the generation of indoor odor and improving air circulation.

[0116] By acquiring environmental odor data in real time, the air conditioner enters the condensation stage when the environmental odor data meets the preset conditions, and the air conditioner enters the frosting stage when the environmental data in the condensation stage meets the preset conditions; the natural process of water vapor condensing and frosting on the evaporator fins can effectively adsorb and remove various odor substances such as cooking odors and pet odors in the air. This process not only does not require additional purification materials, but also has high removal efficiency, which can significantly improve indoor air quality and meet modern people's high requirements for fresh indoor air. Compared with traditional methods such as activated carbon filtration that require regular replacement of filter elements, odor removal is achieved by intelligently controlling the evaporator temperature, without the need for additional maintenance materials, which greatly reduces the maintenance cost of long-term use. It is completely based on physical processes and does not produce any harmful byproducts, ensuring the safety and health of indoor air.

[0117] Reference Figure 2, shows a flow chart of another control method of an air conditioner according to an embodiment of the present invention, which may specifically include the following steps:

[0118] Step 201, obtaining environmental odor data;

[0119] Before using the air conditioner to remove odors, you must first capture the odor and decide whether to turn on the air conditioner to remove odors based on the concentration of odor molecules in the air;

[0120] In one example, the odor concentration in indoor air can be detected by a metal oxide semiconductor sensor (MOS) with a detection range of 0-100 ppm (Parts Per Million), a resolution of 0.1 ppm, and a response time of ≤30 s.

[0121] Metal oxide semiconductor sensors use the adsorption of the measured gas to change the conductivity of the semiconductor and stimulate the alarm circuit by comparing the current change. Because of its very sensitive response, it is widely used in the field of measuring gas concentration. PPM is the abbreviation of Parts Per Million, which means "parts per million". It is used to indicate the trace concentration or proportion of a substance in the total.

[0122] The technology for realizing indoor air odor concentration detection may also be gas chromatography-mass spectrometry technology and electronic nose technology, and the sensor used may also be other electrochemical sensors or photoionization detectors and other devices, which are not limited in the embodiments of the present invention.

[0123] Step 202, when the environmental odor data meets the preset condensation condition, lowering the temperature of the evaporator of the air conditioner to a preset condensation temperature so that water vapor in the air forms a water film on the fins of the evaporator;

[0124] When the odor concentration in the air reaches the threshold specified by the business, the air conditioner begins the odor removal process. The first step is to control the air conditioner to enter the condensation state, and use the physical properties of the condensation process to do preliminary treatment of the odor; at the same time, the condensation stage is also a preparation for the next core step of odor removal, frosting.

[0125] The condensation process of the air conditioner refers to the process in which, during the operation of the air conditioner, the water vapor in the air condenses when it contacts the surface of the evaporator, forming water droplets or a water film because the surface temperature of the evaporator is lower than the dew point temperature of the ambient air. After the water film is formed, the adsorption and dissolution capacity of the water film can be used to absorb and dissolve odorous gases in the air, thereby achieving the purpose of purifying the air.

[0126] In one embodiment, the method further comprises:

[0127] If the environmental odor data does not meet the preset condensation condition, return to the step of obtaining the environmental odor data;

[0128] When the odor data does not meet the condensation conditions, the ambient odor concentration continues to be detected, thereby achieving intelligent cleaning and improving user satisfaction.

[0129] In one embodiment, the preset condensation condition includes a processing threshold, and step 202 includes the following sub-steps:

[0130] S11, when the environmental odor data is greater than or equal to the processing threshold, lowering the temperature of the evaporator of the air conditioner to a preset condensation temperature;

[0131] When the environmental odor data meets the processing threshold, the condensation stage is carried out.

[0132] The method further comprises:

[0133] When the environmental odor data is less than the processing threshold, return to the step of obtaining the environmental odor data.

[0134] When the odor data does not meet the preset processing threshold, the environmental odor concentration continues to be detected, thereby achieving intelligent cleaning and improving user satisfaction.

[0135] Step 203, obtaining environmental data after the temperature of the evaporator is reduced to a preset condensation temperature;

[0136] The environmental data of the air conditioner when it enters the condensation stage is obtained, so as to determine when to enter the next stage according to the environmental data.

[0137] Step 204, when the environmental data meets the preset frosting condition, lowering the temperature of the evaporator to a preset frosting temperature so that the water film on the fin condenses into frost;

[0138] As the temperature drops, the water film condensed on the evaporator is frozen into a frost layer. The physical properties of the frost layer determine that it is a porous solid structure with a large surface area and roughness. When air flows through the frost layer, odorous substances are captured by the pores of the frost layer based on the intermolecular forces.

[0139] In one example, during the frosting process, the working gear of the fan can be increased to speed up the air flow through the frost layer, further improving the deodorization effect.

[0140] In one embodiment, the method further comprises:

[0141] When the environmental data does not meet the preset frosting condition, the process returns to the step of obtaining the environmental data after the temperature of the evaporator is lowered to the preset condensation temperature.

[0142] When the environmental data does not meet the preset frosting condition, the step of obtaining the environmental data after the temperature of the evaporator is reduced to the preset condensation temperature is returned to achieve intelligent frosting of the air conditioner and further improve user satisfaction.

[0143] In one embodiment, the environmental data after the temperature of the evaporator is reduced to the preset condensation temperature includes the evaporator temperature, and the step 204 includes the following sub-steps:

[0144] Sub-step S21, obtaining the mapping relationship between temperature and tension and the mapping relationship between tension and thickness

[0145] Sub-step S22, determining the surface tension of the water film according to the evaporator temperature and the mapping relationship between the temperature and the tension;

[0146] Sub-step S23, determining the thickness of the water film according to the surface tension of the water film and the mapping relationship between the tension and the thickness;

[0147] Sub-step S24, when the thickness of the water film is greater than or equal to a preset thickness threshold, lowering the temperature of the evaporator to a preset frosting temperature;

[0148] The method further comprises:

[0149] When the surface thickness of the water film is less than the preset thickness threshold, the process returns to the step of obtaining the environmental data after the temperature of the evaporator is reduced to the preset condensation temperature.

[0150] Through experiments, the mapping relationship between temperature and water film tension is determined, and then the mapping relationship between water film tension and thickness is determined, making the treatment process more accurate. If the water film thickness does not meet the preset conditions, the data will continue to be monitored to make the water film thickness achieve the best odor removal effect.

[0151] In one embodiment, the method further comprises:

[0152] Acquiring environmental data after the temperature of the evaporator is reduced to a preset frosting temperature;

[0153] Determining the target parameter category and target value that need to be adjusted for the air conditioner according to the environmental data of the frosting stage and a preset frosting model;

[0154] The frosting process is the key process for air conditioner deodorization. The adjustment of the frosting rate directly affects the deodorization effect. The optimal frosting rate that meets the environmental data is obtained by combining the environmental data, and the control parameters of the air conditioner are given according to the rate to achieve precise control of the air conditioner.

[0155] The air conditioner is adjusted according to the target parameter category and the target value.

[0156] According to the parameters provided, the air conditioner is adjusted to make the odor removal process using the frosting process more accurate.

[0157] In one embodiment, the environmental data in the frosting stage includes temperature, humidity and odor data, and determining the target parameter category and target value that need to be adjusted for the air conditioner according to the environmental data in the frosting stage and a preset frosting model includes the following sub-steps:

[0158] Sub-step S31, determining the frosting wind speed and the operating frequency of the frosting compressor according to the temperature, humidity and odor data and the preset frosting model;

[0159] By inputting real-time temperature, humidity and odor data into the preset frost model, the air conditioner operating parameters that meet the current environmental conditions can be calculated more accurately.

[0160] In one example, the preset frosting model can be trained using historical laboratory data and a reinforcement learning algorithm, which can intelligently adjust the operating state of the air conditioner according to environmental changes.

[0161] In the framework of reinforcement learning, the model takes temperature, humidity and odor data as input variables, and frosting wind speed and compressor operating frequency as output variables, i.e., the model's actions. During the training process, the model will continuously try different actions and evaluate the quality of these actions based on, for example, the degree of reduction in odor data. Odor data can be regarded as a reward signal here, and the model will tend to choose those wind speed and compressor operating frequency combinations that can lead to lower odor data.

[0162] In this way, the model can learn how to adjust the operating parameters of the air conditioner under different environmental conditions to achieve the best deodorization effect. The application of this intelligent frosting model can improve the energy efficiency of the air conditioner and user comfort, while reducing unnecessary energy waste and environmental pollution.

[0163] Sub-step S32, determining the target parameter category and target value that need to be adjusted for the air conditioner according to the frosting wind speed and the frosting compressor operating frequency.

[0164] Step 205, obtaining air conditioner data after the temperature of the evaporator is reduced to a preset frosting temperature;

[0165] During the frosting stage, it is necessary to continuously obtain the data of the air conditioner to determine the frosting progress of the air conditioner so that defrosting can be performed at the appropriate time.

[0166] Step 206, when the air conditioner data in the frosting stage meets the preset defrosting condition, raising the temperature of the evaporator to a preset defrosting temperature so that the frost on the fins melts into condensed water and is discharged;

[0167] When the thickness of the frost layer reaches the preset threshold, the defrosting process is started, and the electric auxiliary heating is turned on to increase the temperature and melt the frost layer into condensed water.

[0168] In one embodiment, the air conditioner data after the temperature of the evaporator is reduced to the preset frosting temperature includes the current of the internal fan of the air conditioner; the step 206 includes the following sub-steps:

[0169] Sub-step S41, when the current of the internal fan of the air conditioner is greater than or equal to a preset defrost current threshold, raising the temperature of the evaporator to a preset defrost temperature.

[0170] Step 207, discharging the condensed water formed by melting the frost;

[0171] After the frost layer melts, the condensed water is discharged, taking away the odor molecules to prevent secondary pollution. The frosting and defrosting process can also achieve self-cleaning of the air conditioner evaporator, further preventing the generation of indoor odor and improving air circulation.

[0172] Step 208, obtaining the processed environmental odor data;

[0173] Step 209, when the processed environmental odor data is greater than or equal to the preset odor threshold, return to the step of lowering the temperature of the evaporator of the air conditioner to the preset condensation temperature when the environmental odor data meets the preset condensation condition, so that the water vapor in the air forms a water film on the fins of the evaporator;

[0174] Step 210, when the processed environmental odor data is not less than a preset odor threshold, adjusting the temperature of the evaporator to a temperature set by a user.

[0175] In one embodiment, after step 207, the method may also be:

[0176] Get the running time of this odor processing

[0177] If the odor processing operation time is less than the preset re-processing time threshold, return to the step of obtaining environmental odor data;

[0178] When the odor treatment operation time is greater than or equal to the preset time threshold, the temperature of the evaporator is adjusted to the temperature set by the user.

[0179] By dividing the conditions for stopping odor cleaning into time thresholds, indoor odor cleaning can be completed without delaying user use as much as possible.

[0180] By acquiring environmental odor data in real time, the air conditioner enters the condensation stage when the environmental odor data meets the preset conditions, and the air conditioner enters the frosting stage when the environmental data in the condensation stage meets the preset conditions; the natural process of water vapor condensing and frosting on the evaporator fins can effectively adsorb and remove various odor substances such as cooking odors and pet odors in the air. This process not only does not require additional purification materials, but also has high removal efficiency, which can significantly improve indoor air quality and meet modern people's high requirements for fresh indoor air. Compared with traditional methods such as activated carbon filtration that require regular replacement of filter elements, odor removal is achieved by intelligently controlling the evaporator temperature, without the need for additional maintenance materials, which greatly reduces the maintenance cost of long-term use. It is completely based on physical processes and does not produce any harmful byproducts, ensuring the safety and health of indoor air.

[0181] It should be noted that, for the sake of simplicity, the method embodiments are described as a series of action combinations, but those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.

[0182] Reference Figure 3 , shows a structural block diagram of an embodiment of a control device for an air conditioner of the present invention, which may specifically include the following modules:

[0183] The air conditioner odor detection module 301 is used to obtain environmental odor data;

[0184] Before using the air conditioner to remove odors, you must first capture the odor and decide whether to turn on the air conditioner to remove odors based on the concentration of odor molecules in the air;

[0185] In one example, the odor concentration in indoor air can be detected by a metal oxide semiconductor sensor (MOS) with a detection range of 0-100 ppm (Parts Per Million), a resolution of 0.1 ppm, and a response time of ≤30 s.

[0186] Metal oxide semiconductor sensors use the adsorption of the measured gas to change the conductivity of the semiconductor and stimulate the alarm circuit by comparing the current change. Because of its very sensitive response, it is widely used in the field of measuring gas concentration. PPM is the abbreviation of Parts Per Million, which means "parts per million". It is used to indicate the trace concentration or proportion of a substance in the total.

[0187] The technology for realizing indoor air odor concentration detection may also be gas chromatography-mass spectrometry technology and electronic nose technology, and the sensor used may also be other electrochemical sensors or photoionization detectors and other devices, which are not limited in the embodiments of the present invention.

[0188] The air conditioning condensation temperature control module 302 is used to reduce the temperature of the evaporator of the air conditioner to a preset condensation temperature when the environmental odor data meets the preset condensation condition, so that the water vapor in the air forms a water film on the fins of the evaporator;

[0189] When the odor concentration in the air reaches the threshold specified by the business, the air conditioner begins the odor removal process. The first step is to control the air conditioner to enter the condensation state, and use the physical properties of the condensation process to do preliminary treatment of the odor; at the same time, the condensation stage is also a preparation for the next core step of odor removal, frosting.

[0190] The condensation process of the air conditioner refers to the process in which, during the operation of the air conditioner, the water vapor in the air condenses when it contacts the surface of the evaporator, forming water droplets or a water film because the surface temperature of the evaporator is lower than the dew point temperature of the ambient air. After the water film is formed, the adsorption and dissolution capacity of the water film can be used to absorb and dissolve odorous gases in the air, thereby achieving the purpose of purifying the air.

[0191] A condensation environment detection module 303 is used to obtain environmental data after the temperature of the evaporator is reduced to a preset condensation temperature;

[0192] The environmental data of the air conditioner when it enters the condensation stage is obtained, so as to determine when to enter the next stage according to the environmental data.

[0193] The air conditioning frosting temperature control module 304 is used to reduce the temperature of the evaporator to a preset frosting temperature when the environmental data meets the preset frosting conditions, so that the water film on the fins condenses into frost;

[0194] As the temperature drops, the water film condensed on the evaporator is frozen into a frost layer. The physical properties of the frost layer determine that it is a porous solid structure with a large surface area and roughness. When air flows through the frost layer, odorous substances are captured by the pores of the frost layer based on the intermolecular forces.

[0195] A frosting data detection module 305, for obtaining air conditioner data after the temperature of the evaporator is reduced to a preset frosting temperature;

[0196] During the frosting stage, it is necessary to continuously obtain the data of the air conditioner to determine the frosting progress of the air conditioner so that defrosting can be performed at the appropriate time.

[0197] The air conditioner defrosting temperature control module 306 is used to increase the temperature of the evaporator to a preset defrosting temperature when the air conditioner data in the frosting stage meets the preset defrosting conditions, so that the frost on the fins melts into condensed water and is discharged;

[0198] When the thickness of the frost layer reaches the preset threshold, the defrosting process is started, and the electric auxiliary heating is turned on to increase the temperature and melt the frost layer into condensed water.

[0199] The odor treatment ending module 307 is used to adjust the temperature of the evaporator to the temperature set by the user after the frost melts into condensed water and is discharged.

[0200] After the frost layer melts, the condensed water is discharged, taking away the odor molecules to prevent secondary pollution. The frosting and defrosting process can also achieve self-cleaning of the air conditioner evaporator, further preventing the generation of indoor odor and improving air circulation.

[0201] Optionally, the device further comprises:

[0202] A frosting temperature detection submodule, used to obtain environmental data after the temperature of the evaporator drops to a preset frosting temperature;

[0203] A frosting data acquisition submodule, for determining the target parameter category and target value that need to be adjusted for the air conditioner according to the environmental data of the frosting stage and a preset frosting model;

[0204] The frosting process is the key process for air conditioner deodorization. The adjustment of the frosting rate directly affects the deodorization effect. The optimal frosting rate that meets the environmental data is obtained by combining the environmental data, and the control parameters of the air conditioner are given according to the rate to achieve precise control of the air conditioner.

[0205] The air conditioner frost adjustment submodule is used to adjust the air conditioner according to the target parameter category and the target value.

[0206] According to the parameters provided, the air conditioner is adjusted to make the odor removal process using the frosting process more accurate.

[0207] Optionally, the environmental data in the frosting stage includes temperature, humidity and odor data, and the air conditioner frosting adjustment submodule includes:

[0208] an air conditioning parameter determination unit, for determining a frosting wind speed and a frosting compressor operating frequency according to the temperature, humidity and odor data and the preset frosting model;

[0209] By inputting real-time temperature, humidity and odor data into the preset frost model, the air conditioner operating parameters that meet the current environmental conditions can be calculated more accurately.

[0210] In one example, the preset frosting model can be trained using historical laboratory data and a reinforcement learning algorithm, which can intelligently adjust the operating state of the air conditioner according to environmental changes.

[0211] In the framework of reinforcement learning, the model takes temperature, humidity and odor data as input variables, and frosting wind speed and compressor operating frequency as output variables, i.e., the model's actions. During the training process, the model will continuously try different actions and evaluate the quality of these actions based on, for example, the degree of reduction in odor data. Odor data can be regarded as a reward signal here, and the model will tend to choose those wind speed and compressor operating frequency combinations that can lead to lower odor data.

[0212] In this way, the model can learn how to adjust the operating parameters of the air conditioner under different environmental conditions to achieve the best deodorization effect. The application of this intelligent frosting model can improve the energy efficiency of air conditioners and user comfort, while reducing unnecessary energy waste and environmental pollution.

[0213] The frosting parameter determination subunit is used to determine the target parameter category and target value that need to be adjusted for the air conditioner according to the frosting wind speed and the frosting compressor working frequency.

[0224] The mapping relationship judgment unit is used to return to the step of obtaining the environmental data after the temperature of the evaporator is reduced to the preset condensation temperature when the thickness of the water film is less than the preset thickness threshold.

[0225] Through experiments, the mapping relationship between temperature and water film tension is determined, and then the mapping relationship between water film tension and thickness is determined, making the treatment process more accurate.
