Technical Field

The present application relates to an air purification system, and more particularly, to a system for regulating indoor carbon dioxide concentration through photosynthesis.

Background

Carbon dioxide, PM2.5, and Volatile Organic Compounds (VOCs) are three major causes of indoor air pollution, and most air cleaners are mainly used for processing PM2.5 and part of VOCs at present, but a processing mechanism capable of effectively reducing carbon dioxide is always absent. Furthermore, people are often unwilling to open windows because outdoor air is too cold, too hot, too dirty, or too noisy, resulting in elevated indoor carbon dioxide concentrations, which can be drowsy when the carbon dioxide concentration exceeds 1000ppm, and can be harmful to human health when left in an environment with carbon dioxide concentrations as high as 3000-.

Situations with too high a concentration of carbon dioxide are particularly common in offices and schools, where the concentration of carbon dioxide in offices is often as high as 2500ppm, and the concentration of carbon dioxide in classrooms may even be as high as 5000 ppm. Such a high carbon dioxide environment not only affects the efficiency of work and learning, but is also harmful to health.

Many people think that plants can be set up indoors to consume carbon dioxide exhaled by the human body, but often ignore two important factors: (one) the rate of carbon dioxide consumed by indoor planting often does not keep up with the rate of carbon dioxide production by a group of people; second, most landscape plants cannot be photosynthesized in an environment with a high carbon dioxide concentration, for example, over 1200ppm, and thus, once the indoor carbon dioxide concentration exceeds the concentration range in which photosynthesis can be performed by the plants, the plants do not contribute to the reduction of the indoor carbon dioxide concentration.

Disclosure of Invention

In view of the above, the main objective of the present application is to provide a carbon dioxide concentration adjustment system capable of dynamically adjusting the photosynthesis efficiency of plants so as to control the carbon dioxide concentration in a suitable range.

In order to achieve the above and other objects, the present application provides an active dynamic carbon dioxide concentration adjustment system for indoor planting, comprising a planting group, a plurality of light emitting devices with variable light intensity, a carbon dioxide detector and a controller, wherein the planting group is disposed in an indoor space, the light emitting device is used for emitting light to the planting group according to a control signal to enable the planting group to perform photosynthesis, the carbon dioxide detector is used for detecting the carbon dioxide concentration in the indoor space and emitting a concentration signal, the controller is in signal connection with the light emitting device and the carbon dioxide detector and is used for receiving the concentration signal and providing the control signal, and the controller dynamically adjusts the light intensity of the light emitting device according to the concentration signal to further dynamically adjust the photosynthesis efficiency of the planting group.

This application is through feeding back indoor carbon dioxide concentration to the controller to correspondingly, dynamically adjust light intensity, make photosynthesis efficiency can improve mutually when carbon dioxide concentration increases, thereby avoid or slow down indoor carbon dioxide concentration at least by a wide margin and exceed the target situation.

Detailed Description

Referring to fig. 1, an active type indoor dynamic carbon dioxide concentration adjusting system (hereinafter referred to as an adjusting system) for indoor planting according to a first embodiment of the present application is illustrated, which can be applied to an indoor space and is used to control the carbon dioxide concentration of the indoor space within a suitable range, such as below 1000ppm, or even below 600 ppm. The adjusting system comprises an implanting group 10, a plurality of light emitting devices 20 with variable light intensity, a carbon dioxide detector 30, a controller 40 and at least one fan 50.

The planting group 10 is disposed in the indoor space, and may be composed of a plurality of plants, which may include single plants or multiple plants. As a possible option, the plants in the plant group are for example landscape plants, including but not limited to azalea, ivy, malachite arrowroot, burley eupatorium herb, cyclamen, dendrobium, christmas red, hairyvein agrimonia, goldthread root, acerola, dolichos juba, oroxylum indicum and ficus virens; as a further possible option, the plants in the plant group are for example floating aquatic plants, vanilla plants or other edible plants. In a possible embodiment, the plant group is cultivated hydroponically. Each plant can only photosynthesize in a specific carbon dioxide concentration interval, for example, the suitable carbon dioxide concentration interval of the ivy is about 50-600ppm, and the ivy can not photosynthesize when the carbon dioxide concentration interval is exceeded; taking Christmas red as an example, the concentration range of carbon dioxide is about 100-1200ppm, and beyond this concentration range, Christmas red does not perform photosynthesis; thus, in a preferred set of plants, there are typically a plurality of plants having carbon dioxide concentration ranges with complementary characteristics. On the other hand, each plant has a specific light compensation point and a specific light saturation point, and when the light intensity reaches the light compensation point, the carbon dioxide consumed by photosynthesis of the plant and the carbon dioxide generated by respiration of the plant reach balance; when the light intensity reaches the light saturation point, the carbon dioxide consumed by the photosynthesis of the plant reaches the maximum, the light intensity is continuously increased, and the photosynthesis can not be increased any more; when the light intensity is between the light compensation point and the light saturation point, the greater the light intensity, the higher the carbon dioxide consumed by photosynthesis. In addition, the higher the carbon dioxide concentration, the higher the light saturation point of the plant may be. Generally, the light compensation point and the light saturation point of the negative plant are respectively lower than those of the positive plant, and the carbon dioxide consumption rate of the positive plant is generally higher than that of the negative plant in the environment with high light intensity; therefore, in a preferred planting group, plants with low optical compensation points are usually included to consume carbon dioxide even under low illumination, and plants with high optical saturation points and high maximum carbon dioxide consumption rates are usually included as the main plants for consuming excessive carbon dioxide in the room.

The light emitting devices 20 can emit light to the planting group 10 according to the control signal to enable the planting group to perform photosynthesis, the suitable light emitting devices 20 can be, but are not limited to, light emitting diodes, incandescent lamps, fluorescent lamps, high-pressure gas discharge lamps and neon lamps, and the emitted light is not limited to visible light, and may also include invisible light such as ultraviolet light, infrared light and the like. In a possible embodiment, a plurality of light emitting devices can be placed on the same base, but controlled by independent control signals, for example, a plurality of light emitting diodes which can be independently controlled to emit light are embedded on a substrate. In a possible embodiment, the color temperature value or the spectrum value of the light emitted by the respective light emitting device is a value predetermined by a user or a manufacturer, and the light intensity is adjustable, for example, when different currents are applied, the light emitting diode can emit light with different intensities, and the light emitting device with the adjustable light intensity can emit light with different intensities at different times according to the control signal.

The carbon dioxide detector 30 is installed indoors for detecting the concentration of carbon dioxide in the indoor space and sending out a concentration signal. The controller 40 is in signal communication with the carbon dioxide detector 30 and receives the concentration signal. In one possible embodiment, the carbon dioxide detector 30 detects the concentration of carbon dioxide at regular intervals and sends out a concentration signal, so that the controller 40 can determine the rate of increase or decrease of the concentration of carbon dioxide according to the concentration signals received at the last two times.

The controller 40 is further connected to the light emitting device 20 and provides a control signal, and particularly, the controller 40 can dynamically adjust the light intensity of the light emitting device 20 according to the concentration signal, thereby dynamically adjusting the photosynthesis efficiency of the planting group 10. For example, when the controller 40 determines the increasing rate of the carbon dioxide concentration according to the concentration signals received twice recently, the controller 40 further provides the control signal to enable the light emitting device 20 to increase the light intensity, so that the rate of the carbon dioxide consumed by the planting group 10 due to the photosynthesis is not less than the increasing rate of the carbon dioxide concentration, thereby avoiding or at least slowing down the increase of the carbon dioxide concentration in the room. On the other hand, when the controller 40 determines that the indoor carbon dioxide concentration is reduced, the light intensity can be reduced accordingly, and the photosynthesis efficiency of the plant rows is reduced, thereby saving power.

In order to accurately provide the control signal for regulating the photosynthesis efficiency of the plant group, the controller 40 may store various photosynthesis-related parameters of the plants, including, but not limited to, the relationship between the light intensity of each plant and the photosynthesis efficiency, the carbon dioxide concentration interval in which photosynthesis is possible for each plant, and the number of moles of oxygen generated per unit leaf area per unit time for each plant at a specific light intensity and carbon dioxide concentration, the space volume parameter of the indoor space, and the maximum number of people using the indoor space. On the other hand, the controller can calculate the maximum carbon dioxide concentration increase speed of the indoor space according to the space volume parameter and the maximum number of people using the space volume parameter, thereby providing the suggested information of the proper planting type and the number of the planting group 10, and can calculate the relational expression of the light intensity of the light emitting device 20 for the photosynthesis efficiency of the planting group 10 according to the stored parameters related to the photosynthesis, the planting type and the number of the planting type, thereby realizing the efficacy of dynamically adjusting the photosynthesis efficiency according to the concentration signal provided by the carbon dioxide detector 30.

The fan 50 blows air toward the planting group 10 to blow away oxygen generated by photosynthesis of the planting group, thereby preventing oxygen from being retained around the plants to affect photosynthesis efficiency. In a possible embodiment, the fan 50 is in signal communication with the controller 40, and the controller 40 is further operable to dynamically adjust the ability of the fan 50 to blow off oxygen by increasing or decreasing the speed of the fan 50 in response to the rate at which the carbon dioxide concentration increases or decreases. It should be noted that the controller 40 can be connected to the light emitting device 20, the carbon dioxide detector 30 and the fan 50 by wired or wireless signals.

In the foregoing embodiments, the planting group 10 illustratively contains only a single plant. In the embodiment shown in fig. 2, the planting group 10 is placed in a plurality of shelves, each of which can hold the same or different plants, and each of the plants has a light emitting device 20 thereon, so that in a possible embodiment, the light emitting devices 20 of each layer can be independently controlled, so that the light emitting devices 20 of different layers provide different light intensities.

Through above-mentioned design, this application can realize planting the group initiative ground, dynamically adjust indoor carbon dioxide concentration, let the carbon dioxide concentration of indoor space maintain at the scope of fit to let the user also can breathe the air like the forest in indoor. Other additional advantages of the present application include the ability to simultaneously purify multiple gaseous contaminants other than carbon dioxide through the plant, and improve aesthetics.
