Abstract
Description
Technical Field
[0001] The utility model relates to the field of indoor air purification, and more specifically, to an indoor air purification device applied to an indoor unit of an air conditioner. Background Art
[0002] With the rapid growth of human energy consumption, the emissions of CO2 have also increased sharply, and the resulting global warming has also had a huge impact on the production and life of many countries. In order to slow down climate warming, countries have successively formulated medium- and long-term CO2 emission reduction plans, and carbon capture, utilization and storage (CCUS) is one of the key technologies for reducing carbon emissions.
[0003] In the process of carbon capture, there are two steps: adsorption and desorption of CO2. Adsorption refers to the use of adsorbents (such as liquid amines, solid amines, calcium-based adsorbents, etc.) to adsorb carbon dioxide from flue gas or air. The adsorption process is usually carried out at lower pressure and higher temperature. After the adsorbent is heated to a certain temperature, it contacts with flue gas or air to adsorb carbon dioxide. Desorption refers to the desorption and removal of the adsorbed carbon dioxide on the adsorbent. After the desorbed carbon dioxide is compressed and refrigerated, it is finally liquefied and stored. This process is usually called carbon dioxide stripping or regeneration.
[0004] In the process of adjusting the indoor temperature, traditional air conditioning systems consume a large amount of electric power resources, indirectly resulting in a large amount of carbon dioxide emissions. This problem not only aggravates the trend of global warming, but also causes a large amount of waste of redundant energy of air conditioners. Moreover, existing air conditioning systems often have difficulty in effectively dealing with high concentrations of carbon dioxide indoors, especially in crowded or poorly ventilated environments. High concentrations of carbon dioxide have been proven to affect human health, causing symptoms such as dullness, dizziness, and inattention, reducing work efficiency and quality of life. Although introducing fresh air is a way to improve indoor air quality, in many cases, such as in household environments or other scenarios with strict requirements for air quality, a large amount of air exchange will significantly increase the energy consumption of the air conditioning system. In addition, excessive introduction of fresh air will also bring additional operating pressure to air treatment facilities such as dust removal equipment and humidity control equipment, affecting the efficiency and stability of the overall system.
[0005] Although there are some technical devices that can directly capture carbon dioxide from the environment, these devices are generally large in volume, high in energy consumption, and expensive in cost, restricting their application in actual scenarios. Summary of the Utility Model

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0034] The present application proposes an indoor air purification device applied to an indoor unit of an air conditioner, which can effectively reduce the indoor carbon dioxide concentration, improve the indoor air quality, and the device has a small volume and low cost. The structure of the indoor air purification device is as shown in the attached Figures 1-3 drawing, and the specific scheme is as follows:
[0035] An indoor air purification device applied to an indoor unit of an air conditioner, the indoor air purification device 1 is connected to an external indoor unit 0 of an air conditioner, and the positional relationship between the indoor air purification device 1 and the external indoor unit 0 of an air conditioner is as shown in the attached Figure 4 drawing and the attached Figure 5 drawing. Among them, the indoor air purification device 1 includes a housing 5 and a fan 2, a heating module 44 and a gas treatment module 3 located inside the housing 5; the fan 2 forms an air duct, an air inlet 21 and an air outlet 22 inside the housing, the air inlet 21 is communicated with the indoor, and the air outlet 22 is respectively communicated with the indoor and the water outlet pipe of the indoor unit of the air conditioner. The heating module 44 and the gas treatment module 3 are both located on the air duct, and air can flow out of the air outlet 22 after passing through the heating module 44 and the gas treatment module 3 under the action of the fan 2. The heating module 44 and the gas treatment module 3 are located between the fan 2 and the air outlet 22.
[0036] Among them, the heating module 44 is close to the gas treatment module 3 and is used to heat the gas treatment module 3; an adsorbent is provided in the gas treatment module 3, which is used to adsorb carbon dioxide in indoor air through the adsorbent and desorb carbon dioxide in the adsorbent under heating conditions; the fan 2 is used to extract indoor air from the air inlet 21 and discharge it into the gas treatment module 3, and discharge the gas adsorbed by the gas treatment module 3 from the air outlet 22 into the indoor or discharge the carbon dioxide desorbed by the gas treatment module 3 from the air outlet 22 to the outside through the pipeline of the indoor unit of the air conditioner.
[0037] The complete process is as shown in the attached Figure 6 and the attached Figure 7 as follows: When running the adsorption, the indoor air is extracted by the blower 2 and enters the gas treatment module 3. The carbon dioxide in the extracted air is adsorbed by the adsorbent in the gas treatment module 3 to obtain low-carbon air with a lower carbon dioxide content. The low-carbon air is then discharged back into the room through the blower 2 to cyclically adsorb carbon dioxide and reduce the carbon dioxide concentration in the indoor air. When the adsorption has been carried out for a certain period of time or the adsorbent can no longer adsorb carbon dioxide, carbon dioxide desorption is required. When running the desorption, the indoor or outdoor air (when the air conditioner has a fresh air system) is extracted by the blower 2 and enters the gas treatment module 3, and the heating module 4 is turned on to heat the gas treatment module 3. When the temperature reaches a specific desorption temperature, the carbon dioxide desorbs from the adsorbent and mixes with the indoor air to form high-carbon air, which is discharged outdoors through the pipeline of the indoor unit 0 of the air conditioner. The adsorbent that has completed desorption can continue to be used for adsorption treatment to achieve recycling.
[0038] In this application, the indoor air purification device 1 is integrated on the indoor unit 0 of the air conditioner, and the pipeline of the indoor unit 0 of the air conditioner is required to transport carbon dioxide outdoors. The indoor air purification device 1 can be built into the indoor unit 0 of the air conditioner or attached to the outside of the indoor unit 0 of the air conditioner. The indoor unit 0 of the air conditioner, also known as the indoor unit, is the part of the air conditioning system responsible for processing and distributing cold and hot air and is usually located indoors. It is connected to the outdoor unit (or the external unit) through refrigerant pipelines, electrical lines, and drain pipes to jointly complete the functions of refrigeration, heating, and dehumidification of the air conditioning system. Preferably, the indoor unit 0 of the air conditioner includes a wall-mounted air conditioner indoor unit, a cabinet-type air conditioner indoor unit, or a ceiling-mounted air conditioner indoor unit. In some specific embodiments, the indoor unit 0 of the air conditioner is wall-mounted, and the indoor air purification device 1 is located on both sides or the upper side of the indoor unit 0 of the air conditioner. The attached Figure 4 shows the schematic positional relationship where the indoor air purification device 1 is located on the left side of the wall-mounted air conditioner indoor unit 0. The attached Figure 5 shows the schematic positional relationship where the indoor air purification device 1 is located on the right side of the wall-mounted air conditioner indoor unit 0.
[0039] The wall-mounted air conditioner indoor unit 0 is one of the most common types of air conditioners in current households and small office environments. It is usually installed on the wall and does not require a complex installation process. Compared with the central air conditioning system, the installation cost is relatively low. Due to its compact design, it does not occupy too much indoor space, especially suitable for small-sized apartments or rooms with limited space. The indoor air purification device 1 of the present application is small in volume and light in weight, and can be installed on the wall together with the air conditioner indoor unit 0 to minimize the occupation of indoor space. The wall-mounted air conditioner indoor unit 0 is usually connected to the outdoor unit through refrigerant pipes and electric wires. The outdoor unit is responsible for compressing the refrigerant and dissipating heat, and the two work together to complete the refrigeration or heating process. The indoor air purification device 1 of the present application only needs to discharge carbon dioxide gas through a pipe, and can add the function of carbon dioxide treatment to the air conditioner without changing the existing structure of the air conditioner. It can work either in combination with the air conditioning system or independently of the air conditioning system, and does not require complex system control.
[0040] Specifically, the fan 2 is responsible for extracting indoor air, discharging the gas after being processed by the gas treatment module 3 into the room, and discharging the desorbed carbon dioxide outdoors. By continuously circulating and processing the air, the indoor carbon dioxide concentration is reduced. Preferably, the fan 2 is a centrifugal fan 2, installed on one side of the gas treatment module 3, extracting indoor gas through the gas treatment module 3, and then discharging the gas from the air outlet 22 of the fan 2. In some specific embodiments, it further includes a control module, and the control module is electrically connected to the heating module 4, and / or the fan 2, and / or the gas treatment module 3, and controls the operation of the heating module 4, and / or the fan 2, and / or the gas treatment module 3 through the control module.
[0041] Preferably, the inlet surface size of the fan 2 is the same as the windward surface size of the gas treatment module 3, and they are attached together through a special sealing method to ensure the full use of the adsorbent in the gas treatment module 3. In addition, the gas treatment module 3 for adsorbing carbon dioxide and the centrifugal fan 2 can be integrated into the interior of the housing to form an integrated design.
[0042] Specifically, an adsorbent is provided in the gas treatment module 3 for adsorbing carbon dioxide in the gas through the adsorbent and desorbing the carbon dioxide in the adsorbent under heating conditions. The adsorbent is mainly used for adsorbing carbon dioxide. Preferably, the adsorbent is a solid amine. Utilizing the chemical properties of amine substances in the solid state to adsorb and capture carbon dioxide is an efficient and environmentally friendly carbon dioxide capture method. Solid amine materials usually have a high surface area and abundant amine groups, which can provide a large number of adsorption sites to achieve high-efficiency adsorption. Moreover, the energy consumption during the desorption of CO2 by solid amine adsorption and the regeneration of amine materials is lower, reducing energy consumption, being recyclable, and reducing the gas treatment cost. In addition, solid amine materials have good chemical stability and thermal stability, can maintain stable performance within a wide temperature range, are not easily volatile during the adsorption and desorption processes, reduce the potential environmental pollution of amine substances, and are suitable for indoor air purification.
[0043] In some specific embodiments, a framework is provided on the gas treatment module 3, and the adsorbent is coated, impregnated, or loaded on the framework. The framework can be a glass fiber framework, a metal framework, a high-temperature resistant plastic framework, etc. The solid amine is combined with the framework by means such as coating, impregnation, and loading. Selecting a solid amine with strong antioxidant properties as the adsorption material, carbon dioxide can be desorbed using air as the carrier gas at a temperature below 110 °C. Using air as the carrier gas can reduce the partial pressure of carbon dioxide and improve the desorption efficiency. After reaching a certain desorption temperature, the adsorbed solid amine will be desorbed. During desorption, the blower 2 continuously conveys indoor air, and the desorbed gas together with the carrier gas is discharged into the drain pipe of the indoor unit 0 of the air conditioner.
[0044] The adsorption and desorption of carbon dioxide by the adsorbent can be achieved by controlling the temperature. The heating module 4 can select an electric heating device to heat-treat the gas treatment module 3 using the built-in power supply. In some specific embodiments, the heating module 4 is internally provided with a honeycomb heating block or a fin-shaped heating block to accelerate heat transfer by increasing the surface contact area to improve the heat exchange efficiency.
[0045] In some specific embodiments, a multi-way valve is further included. The multi-way valve includes at least three valve ports. One valve port is connected to the air outlet 22 through a pipeline, one valve port is connected to the pipeline of the indoor unit 0 of the air conditioner through a pipeline, and one valve port is connected to the indoor through a pipeline. Exemplarily, if the drain pipe of the indoor unit 0 of the air conditioner discharges carbon dioxide, the multi-way valve is connected to the air outlet 22 of the indoor unit 0 of the air conditioner, the drain pipe of the indoor unit 0 of the air conditioner, and the indoor through pipelines respectively. The multi-way valve is equivalent to providing two output ports and one input port, and discharging the gas at the input port through one of the output ports. During adsorption, the gas enters the room; during desorption, the gas enters the pipeline of the indoor unit 0 of the air conditioner.
[0046] In some specific embodiments, the air outlet 22 is connected to the water outlet pipe of the indoor unit 0 of the air conditioner, and is used to discharge carbon dioxide through the water outlet pipe. The water outlet pipe of the indoor unit 0 of the air conditioner, also known as the condensate pipe or drain pipe, is an important part of the air conditioner system for discharging condensate water. When the air conditioner operates in the cooling mode, the evaporator coil of the indoor unit cools the air, and the moisture in the air condenses into water droplets when it meets the cold. These water droplets need to be discharged outdoors or into the sewer through the water outlet pipe to keep the indoor dry and the air conditioner running normally. The water outlet pipe is convenient for modification, and the modification will not affect the normal operation of the air conditioner.
[0047] The indoor air purification device 1 can operate only by time control, start desorption after adsorption is completed at a specific time, and start adsorption after desorption is completed at a specific time. The indoor carbon dioxide concentration can be reduced through multiple rapid adsorption-desorption cycles. It can also be controlled by adding a carbon dioxide sensor to collect data. For example, a carbon dioxide detector is set at the outlet of the fan 2 during adsorption. When the carbon dioxide concentration at the outlet is high, the adsorption can be stopped. In some specific embodiments, it further includes a gas sensor located at the air outlet 22 for detecting the carbon dioxide concentration at the air outlet 22; and / or, it further includes a temperature sensor located at the gas treatment module 3. The gas sensor can be used to detect the adsorption capacity of the adsorbent. During the adsorption process, when the gas sensor at the air outlet 22 detects a high carbon dioxide concentration in the gas at that place, it can be determined that the adsorption capacity of the adsorbent is poor at this time. It may be that the adsorption capacity of the adsorbent has reached saturation and desorption is required, or the adsorption performance of the adsorbent has deteriorated due to long-term use and needs to be replaced. The temperature sensor can be used to detect the temperature of the gas treatment module 3. The adsorbent performs adsorption and desorption at a specific temperature. As a feedback unit of the heating module 4, the temperature sensor can obtain the temperature information of the gas treatment module 3 in real time.
[0048] In some specific embodiments, both the gas treatment module 3 and the heating module 4 are in a disc shape, and the gas treatment module 3 and the heating module 4 are overlapped and distributed. The modular design enables users to set one or more gas treatment modules 3 and heating modules 4 according to different carbon dioxide treatment requirements. The gas treatment module 3 and the heating module 4 adopt a hollow structure design with extremely low working resistance (lower than 40 pa). A low-pressure silent fan 2 can achieve a large air volume, quickly adsorb carbon dioxide, and the equipment operation cost is very low. Figure 3 The structural schematic diagrams of the heating module 4 and the gas treatment module 3 are given. The gas treatment modules 3 are respectively arranged on both sides of the heating module 4, which can fully realize the heating of the gas treatment module 3, improve the heating efficiency, and reduce the heating cost.
[0049] In some specific embodiments, heat-generating areas are distributed on the outer surface of the indoor unit 0 of the air conditioner. The gas treatment module 3 is close to the heat-generating areas and is used for desorption by means of the heat generated by the indoor unit 0 of the air conditioner. For example, in order to drive the fan to operate and make it blow air over the evaporator, the motor and fan assembly in the indoor unit also generate heat, especially in the case of long-term continuous operation. Components such as the electronic control board, sensors, and relays in the indoor unit generate a certain amount of heat during operation. One side of the gas treatment module 3 is close to these heat-generating areas, and the other side is close to the heating module 4 to achieve full utilization of thermal energy.
[0050] The present utility model provides an indoor air purification device applied to the indoor unit of an air conditioner. The carbon capture technology is applied to indoor air purification, and carbon dioxide is discharged through the pipeline of the indoor unit of the air conditioner. It can effectively capture and process carbon dioxide in indoor air, reduce the indoor carbon dioxide concentration, improve the indoor air quality, and the device has a small volume and low cost, and can be integrated into the indoor unit of the air conditioner to expand the functionality of the air conditioner.
