Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning condensation adsorption, and particularly to an allergen purification method and system based on the air-conditioning condensation adsorption principle. Background Art

[0002] With the increasingly prominent air quality problems in the modern urban environment, more and more people are troubled by seasonal allergies. Especially during the high pollen season in spring and autumn, symptoms such as allergic asthma and rhinitis occur frequently. For people with severe pollen allergies, long-term ventilation is often not advisable, and the air quality in enclosed spaces will decline, leading to an increased health risk.

[0003] In addition, even when the doors and windows are closed, allergens such as pollen and dust mites may still be brought into the room by occupants through clothing, hair, etc. and deposited in areas such as bedding, sofas, and carpets, becoming a hidden source of indoor allergic reactions. Therefore, an allergen purification method and system based on the air-conditioning condensation adsorption principle are proposed. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide an allergen purification method and system based on the air-conditioning condensation adsorption principle, which solves the problem of a large amount of allergens such as pollen and dust mites deposited indoors.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An allergen purification system based on the air-conditioning condensation adsorption principle, comprising: a central control unit, a user control terminal, a desensitization mode trigger module, a fresh air volume control module, a wind speed adjustment module, a compressor frequency conversion control module, a particulate matter concentration detection module, and a temperature detection module;

[0007] The output end of the user control terminal is electrically connected to the input end of the central control unit, the output end of the desensitization mode trigger module is electrically connected to the input end of the central control unit, the output end of the particulate matter concentration detection module is electrically connected to the input end of the central control unit, the output end of the temperature detection module is electrically connected to the input end of the central control unit, the output end of the central control unit is electrically connected to the input end of the fresh air volume control module, the output end of the central control unit is electrically connected to the input end of the wind speed adjustment module, and the output end of the central control unit is electrically connected to the input end of the compressor frequency conversion control module.

[0008] Preferably, the central control unit is the core of the system control. The desensitization mode trigger module is used to receive the desensitization instruction issued by the user or the system policy. The user control end is the manual input interface. The central control unit receives the feedback signal of the indoor temperature transmitted by the temperature sensor, and issues control instructions to the wind speed adjustment module, the fresh air volume control module and the compressor frequency conversion module, so as to realize various collaborative control operations in the desensitization mode. The control process is clear and the feedback path is clear, which has the potential for engineering implementation and industrial transformation.

[0009] Preferably, it further includes: an indoor unit of the air conditioner. A condensation fin is installed inside the indoor unit of the air conditioner. A refrigerant pipe is installed inside the indoor unit of the air conditioner. One end of the refrigerant pipe extends outside the indoor unit of the air conditioner. An outdoor unit of the air conditioner is installed at the end of the refrigerant pipe away from the indoor unit of the air conditioner. A drain pipe is fixedly connected inside the indoor unit of the air conditioner, and one end of the drain pipe extends outside the indoor unit of the air conditioner. A first fresh air duct is installed inside the indoor unit of the air conditioner. A drawer-type fresh air filter box is installed inside the indoor unit of the air conditioner. One end of the first fresh air duct is fixedly connected to the drawer-type fresh air filter box. A second fresh air duct is fixedly connected to the side of the drawer-type fresh air filter box away from the first fresh air duct, and one end of the second fresh air duct extends outside the indoor unit of the air conditioner. An air inlet part of the air conditioner is arranged above the indoor unit of the air conditioner, and an air outlet part of the air conditioner is arranged below the indoor unit of the air conditioner. Through the unique condensation adsorption principle, it can effectively adsorb allergen particles such as pollen, dust mites, and mold spores in the air. Utilizing the continuously maintained low temperature state on the surface of the condenser, it promotes water vapor to condense into water droplets and adsorb particulate matter. Compared with the traditional filter screen filtering method, there is no need to frequently replace the filter screen, which greatly improves the removal efficiency of allergens and provides a cleaner and healthier indoor air environment for allergic people.

[0010] Preferably, it includes the following steps:

[0011] S1: After the desensitization operation mode of the air conditioner is turned on, the system automatically conducts self-checks on each component, including checking whether the indoor unit of the air conditioner, the outdoor unit of the air conditioner, the temperature detection module, the particulate matter concentration detection module, the air damper of the fresh air duct, and the drainage system are working properly. At the same time, it reads the desensitization parameters preset by the user, such as the difference between the target temperature of the condenser and the room temperature, the fresh air ratio, the operation duration, etc. If the user does not set them, the system default values are adopted. The target temperature of the condenser is lower than the room temperature, and the fresh air ratio is set to 15%-25%;

[0012] S2: The indoor temperature detection module is used to collect the indoor environmental temperature in real time, and the particulate matter concentration detection module detects the concentration of allergen particles such as pollen, dust mites, and mold spores in the indoor air, and transmits the collected data to the central control unit;

[0013] S3: Based on the collected indoor temperature and combined with the temperature difference value preset by the user or defaulted by the system, the central control unit accurately sets the target temperature of the condenser to ensure that the condenser temperature is 2 - 5°C lower than the room temperature, creating conditions for water vapor condensation;

[0014] S4: Through the compressor variable - frequency control module and the central control unit, according to the real - time difference between the indoor temperature and the condenser temperature, dynamically adjust the operating frequency and power of the compressor. When the condenser temperature is higher than the target temperature, increase the compressor power and operating frequency to enhance the refrigeration effect. When the condenser temperature approaches or reaches the target temperature, reduce the compressor power and operating frequency to maintain the condenser temperature stable within the set range, enabling the condenser to continuously operate at a low temperature and prompting the water vapor in the air to condense into condensation beads on the surface of the condenser;

[0015] S5: The fan adjustment module adjusts the operating wind speed of the fan to the medium - low wind speed range, and the wind speed is specifically set to the specific wind speed values corresponding to gears 1 - 3 to avoid the resuspension of particulate matter in the air due to too high a wind speed, and at the same time enable the air to have sufficient residence time on the surface of the condenser, enhancing the contact probability between particulate pollutants in the air and the condensation beads;

[0016] S6: According to the preset fresh - air ratio, the central control unit controls the opening degree of the damper in the fresh - air channel to introduce external fresh air, and through the air - duct design, forces the fresh air to flow through the area near the condenser before entering the room, improving the contact efficiency between particulate pollutants in the fresh air and the condensed water. During the process of introducing fresh air, the replaceable drawer - type filter equipped in the fresh - air channel preliminarily filters the fresh air to remove larger - particle pollutants;

[0017] S7: When the indoor air or the introduced fresh air contacts the surface of the condenser, particulate pollutants such as pollen, dust mites, and mold spores suspended in the air are adsorbed by the condensation beads. As the condensation beads continuously aggregate and grow, the condensation beads adsorbed with particulate matter slide down along the condenser fins to the drainage tray under the action of gravity;

[0018] S8: The drainage tray discharges the collected condensed water containing particulate matter to the outside through the drainage pipe. The drainage pipe is set with a certain slope, and the slope is 3° - 5°, to ensure that the condensed water can be discharged smoothly and prevent water accumulation from causing bacterial growth and odor generation;

[0019] S9. During the desensitization operation, the central control unit continuously receives the data fed back by the temperature detection module and the particulate matter concentration detection module. According to the changes in indoor temperature, the temperature fluctuation of the condenser, and the change in the concentration of indoor allergen particles, it adjusts the operating frequency of the compressor, the wind speed of the fan, and the fresh air ratio in real time to ensure the stability and efficiency of the desensitization effect. When the indoor particulate matter concentration is relatively high, the fresh air ratio is appropriately increased and the fan wind speed is reduced. At this time, the air conditioner continuously operates to discharge the indoor air, and by increasing the fresh air ratio, the outdoor air is replaced with the indoor air, thereby quickly reducing the indoor particulate matter concentration and diluting the content of indoor allergens. At the same time, the drawer-type fresh air filter box inside the air conditioner effectively filters the air entering the room to prevent outdoor allergens from entering the room. When the indoor temperature changes greatly, the refrigeration intensity of the compressor is adjusted in a timely manner;

[0020] S10. The system determines whether the desensitization operation mode has ended according to the preset operation duration or the user's manual instruction. If the preset duration is reached or the user manually stops, the central control unit controls components such as the compressor, the fan, and the fresh air duct damper to stop operating. At the same time, it records the relevant data of this desensitization operation, such as the operation duration, the power consumption, and the removed particulate matter concentration, etc., for the user to query and analyze.

[0021] Preferably, this method is applicable to wall-mounted, floor-standing, and central air-conditioning systems. By making adaptability adjustments to the air ducts, condensation structures, and control systems of different types of air-conditioning systems, the desensitization function is realized.

[0022] Preferably, for wall-mounted air conditioners, the air duct design can be optimized to make the air flow through the condenser better. For floor-standing air conditioners, the area of the condenser can be increased to improve the desensitization efficiency. For central air-conditioning systems, centralized control and unified management of the desensitization operation of multiple indoor units can be realized.

[0023] Preferably, the desensitization operation mode includes controlling the compressor to operate at a low load or in a variable-frequency manner. The compressor power is reduced to 30%-60% of the normal refrigeration power, the wind speed is reduced to reduce the resuspension of particulate matter, and the condenser is maintained to work continuously.

[0024] Preferably, the desensitization mode can be set by the user through the air-conditioning control panel or the remote control terminal, and can also be started regularly or automatically triggered by the particulate matter concentration detection module. The user can conveniently turn on or off the desensitization mode, set the operation parameters, and view the indoor air quality and the desensitization operation status in real time at any location through the mobile phone APP, and continuously and stably operate for at least 30 minutes or more to realize the gradual adsorption and export of particulate matter such as pollen in the air.

[0025] Preferably, the surface structure of the condenser includes a hydrophilic coating or surface micro-protrusions, which are used to enhance the uniformity of water droplet distribution and the particle adsorption ability.

[0026] Preferably, the fresh air duct is arranged near the condenser to increase the contact probability between particulate pollutants in the air and condensed water.

[0027] The technical effects and advantages of an allergen purification method and system based on the air-conditioning condensation adsorption principle of the present invention are as follows:

[0028] 1. This invention realizes an active desensitization process without a high-efficiency filter, reducing the equipment maintenance frequency and consumable costs.

[0029] 2. This invention replaces major structural modifications with optimized operation strategies, has strong adaptability, and is convenient for rapid integration into the air-conditioning system.

[0030] 3. This invention realizes a low-energy-consumption and sustainable particulate discharge process by dynamically controlling the condensation temperature difference and wind speed.

[0031] 4. This invention can carry out all-weather purification operation for high-sensitivity areas such as bedrooms, baby rooms, and allergic people.

[0032] 5. This invention has a clear control process and a clear feedback path, and has the potential for engineering implementation and industrial transformation.

[0033] 6. Through the unique condensation adsorption principle, this invention can effectively adsorb allergen particles such as pollen, dust mites, and mold spores in the air. By utilizing the continuously maintained low temperature state on the surface of the condenser, water vapor is condensed into water droplets and adsorbs particulate matter. Compared with the traditional filter screen filtration method, it is not necessary to frequently replace the filter screen, greatly improving the removal efficiency of allergens and providing a cleaner and healthier indoor air environment for allergic people.

A refrigerant pipe 3 is installed inside the indoor unit 2 of the air conditioner. One end of the refrigerant pipe 3 extends outside the indoor unit 2 of the air conditioner. An outdoor unit 1 of the air conditioner is installed at the end of the refrigerant pipe 3 away from the indoor unit 2 of the air conditioner. A drain pipe 4 is fixedly connected inside the indoor unit 2 of the air conditioner, and one end of the drain pipe 4 extends outside the indoor unit 2 of the air conditioner. A first fresh air duct 7 is installed inside the indoor unit 2 of the air conditioner. A drawer-type fresh air filter box 8 is installed inside the indoor unit 2 of the air conditioner. One end of the first fresh air duct 7 is fixedly connected to the drawer-type fresh air filter box 8. A second fresh air duct 10 is fixedly connected to the side of the drawer-type fresh air filter box 8 away from the first fresh air duct 7, and one end of the second fresh air duct 10 extends outside the indoor unit 2 of the air conditioner. An air inlet part 5 of the air conditioner is arranged above the indoor unit 2 of the air conditioner. An air outlet part 6 of the air conditioner is arranged below the indoor unit 2 of the air conditioner. Through the unique condensation adsorption principle, it can effectively adsorb allergen particles such as pollen, dust mites, and mold spores in the air. Utilizing the continuously maintained low temperature state on the surface of the condenser, it promotes water vapor to condense into water droplets and adsorb particulate matter. Compared with the traditional filter screen filtration method, there is no need to frequently replace the filter screen, greatly improving the removal efficiency of allergens and providing a cleaner and healthier indoor air environment for allergic people.

[0045] Specifically, it includes the following steps:

[0046] S1: After the desensitization operation mode of the air conditioner is turned on, the system automatically conducts self-checks on each component, including checking whether the indoor unit 2 of the air conditioner, the outdoor unit 1 of the air conditioner, the temperature detection module, the particulate matter concentration detection module, the air damper of the fresh air duct, and the drainage system are working properly. At the same time, it reads the desensitization parameters preset by the user, such as the difference between the target temperature of the condenser and the room temperature, the fresh air ratio, the operation duration, etc. If the user does not set them, the system default values are adopted. The target temperature of the condenser is lower than the room temperature, and the fresh air ratio is set to 15%-25%.

[0047] S2: Use the indoor temperature detection module to continuously collect the indoor environmental temperature, and the particulate matter concentration detection module to detect the concentration of allergen particles such as pollen, dust mites, and mold spores in the indoor air, and transmit the collected data to the central control unit.

[0048] S3: Based on the collected indoor temperature and combined with the temperature difference value preset by the user or the system default, the central control unit accurately sets the target temperature of the condenser to ensure that the condenser temperature is 2 - 5°C lower than the room temperature, creating conditions for water vapor condensation;

[0049] S4: Through the compressor variable frequency control module and the central control unit, according to the real-time difference between the indoor temperature and the condenser temperature, dynamically adjust the operating frequency and power of the compressor. When the condenser temperature is higher than the target temperature, increase the compressor power and operating frequency to enhance the refrigeration effect. When the condenser temperature approaches or reaches the target temperature, reduce the compressor power and operating frequency to maintain the condenser temperature stable within the set range, enabling the condenser to continuously operate at a low temperature state, promoting the condensation of water vapor in the air on the surface of the condenser to form condensed water droplets;

[0050] S5: The fan adjustment module adjusts the operating wind speed of the fan to the medium - low wind speed range, and the wind speed is specifically set to the specific wind speed values corresponding to gears 1 - 3 to avoid the resuspension of particulate matter in the air due to too high a wind speed, and at the same time ensure that the air has sufficient residence time on the surface of the condenser, enhancing the contact probability between particulate pollutants in the air and condensed water droplets;

[0051] S6: According to the preset fresh air ratio, the central control unit controls the opening degree of the damper in the fresh air passage to introduce external fresh air, and through the air duct design, forces the fresh air to flow through the area near the condenser before entering the room, improving the contact efficiency between particulate pollutants in the fresh air and condensed water. During the process of introducing fresh air, the replaceable drawer - type filter equipped in the fresh air passage preliminarily filters the fresh air to remove pollutants with larger particles;

[0052] S7: When the indoor air or the introduced fresh air contacts the surface of the condenser, particulate pollutants such as pollen, dust mites, and mold spores suspended in the air are adsorbed by the condensed water droplets. As the condensed water droplets continuously aggregate and increase in size, the condensed water droplets adsorbed with particulate matter slide down along the condenser fins to the drain tray under the action of gravity;

[0053] S8: The drain tray discharges the collected condensed water containing particulate matter to the outside through the drain pipe 4. The drain pipe 4 is set with a certain slope, and the slope is 3° - 5°, to ensure that the condensed water can be discharged smoothly, preventing water accumulation from causing bacterial growth and odor generation;

[0054] S9. During the desensitization operation, the central control unit continuously receives the data feedback from the temperature detection module and the particulate matter concentration detection module. According to the changes in indoor temperature, condenser temperature fluctuations, and the concentration of indoor allergen particles, it adjusts the operating frequency of the compressor, the wind speed of the fan, and the fresh air ratio in real time to ensure the stability and efficiency of the desensitization effect. When the indoor particulate matter concentration is high, the fresh air ratio is appropriately increased and the fan wind speed is reduced. At this time, the air conditioner continuously operates to exhaust the indoor air, and by increasing the fresh air ratio, the outdoor air is replaced with the indoor air, thereby quickly reducing the indoor particulate matter concentration and diluting the content of indoor allergens. At the same time, the drawer-type fresh air filter box 8 inside the air conditioner effectively filters the air entering the room to prevent outdoor allergens from entering the room. When the indoor temperature changes greatly, the refrigeration intensity of the compressor is adjusted in a timely manner;

[0055] S10. The system determines whether the desensitization operation mode ends according to the preset operation duration or the user's manual instruction. If the preset duration is reached or the user manually stops, the central control unit controls components such as the compressor, the fan, and the fresh air duct damper to stop operating. At the same time, it records the relevant data of this desensitization operation, such as the operation duration, power consumption, and removed particulate matter concentration, for the user to query and analyze.

[0056] Specifically, this method is applicable to wall-mounted, floor-standing, and central air-conditioning systems. By making adaptive adjustments to the air ducts, condensation structures, and control systems of different types of air-conditioning systems, the desensitization function is realized. For wall-mounted air conditioners, the air duct design can be optimized to make the air flow through the condenser better. For floor-standing air conditioners, the area of the condenser can be increased to improve the desensitization efficiency. For central air-conditioning systems, centralized control and unified management of the desensitization operation of multiple indoor units can be achieved.

[0057] Specifically, the desensitization operation mode includes controlling the compressor to operate at a low load or in a variable-frequency manner. The compressor power is reduced to 30%-60% of the normal refrigeration power, the wind speed is reduced to reduce particulate matter resuspension, and the condenser is maintained to work continuously. All-weather purification operation can be carried out for highly sensitive areas such as bedrooms, baby rooms, and allergic people.

[0058] Specifically, the desensitization mode can be set by the user through the air conditioner control panel or the remote control terminal, or it can be started regularly or automatically triggered by the particulate matter concentration detection module. The user can conveniently turn on or off the desensitization mode, set the operation parameters, and view the indoor air quality and desensitization operation status in real time at any location through the mobile phone APP, and continuously and stably operate for at least 30 minutes or more to gradually adsorb and export particulate matter such as pollen in the air. By dynamically controlling the condensation temperature difference and the wind speed, a low-energy-consumption and sustainable particulate matter discharge process is realized.

[0059] Specifically, the fresh air passage is arranged near the condenser to increase the contact probability between particulate pollutants in the air and condensed water. The surface structure of the condenser includes a hydrophilic coating or surface micro-protrusions, which are used to enhance the uniformity of water droplet distribution and the particle adsorption capacity.

At this time, the air conditioner continues to run to exhaust the indoor air, and by increasing the fresh air ratio, the outdoor air is replaced with the indoor air, thereby quickly reducing the indoor particle concentration and diluting the indoor allergen content. At the same time, the drawer-type fresh air filter box (8) inside the air conditioner effectively filters the air entering the room to prevent outdoor allergens from entering the room. When the indoor temperature changes greatly, the refrigeration intensity of the compressor is adjusted in time; S10. The system determines whether the desensitization operation mode has ended based on the preset operating time or the user's manual instruction. If the preset time is reached or the user manually stops it, the central control unit controls the compressor, fan, fresh air duct damper and other components to stop running, and records the relevant data of this desensitization operation, such as operating time, power consumption, concentration of removed particles, etc., for user query and analysis.
