Description

Design method of green plant humidifying system with self-adjusting function
Technical Field
The invention relates to the technical field of green plant humidification, in particular to a design method of a green plant humidification system with a self-adjusting function.
Background
In recent years, people live in the air and are in contact with the air at all times. As one of the main media for exchanging substances with the outside, high quality air has become an important content for people's fine living needs. Humidity is one of the key parameters of air quality, and directly influences subjective feeling of people. When the relative humidity is 50% -60%, the human body feels most comfortable. In addition, excessive or insufficient air humidity is harmful to human health. When the humidity is too high, the secretion of the pineal hormone in the human body is large, which inhibits the concentration of the thyroxine and the adrenaline, and the human body feels that the semen is not extracted and the people are cachectic and malaise. When the humidity is too small, the evaporation is accelerated, and the dry air easily takes away the moisture of the human body, so that the human skin is dry and cracked, and the mucous membranes of the oral cavity and the nasal cavity are stimulated, thereby causing the symptoms of thirst, dry cough, hoarseness, laryngalgia and the like.
In order to adjust the air humidity, an atomization humidifier and an air conditioner dehumidifier are commonly used at present. Although the machine equipment can quickly realize the humidification and dehumidification effects on local air, the atomization humidification and air conditioning dehumidification are limited by considering the factors of space, time efficiency, energy consumption, green and low carbon in the process, ecological and environmental protection and the like.
Due to the effects of light absorption, covering and shielding and transpiration, the plants have the functions of cooling and humidifying. However, the related application research at present only considers the cooling and humidifying functions of vegetation in large-scale greening, and how to design the vegetation into a controllable system with a clear humidifying function is short of technologies and processes with feasibility. The humidification function of a humidifier is combined with the beautifying and purifying functions of green plants, but the humidification function is realized by atomizing humidification or spraying gas-liquid contact, and the green plants do not become core components for realizing the humidification function in the design systems. In particular, when green root-impregnated water (water for plant cultivation) is used as humidification source water, there is a potential problem of microbial contamination and the like.
The green plant arrangement is used for landscape design, and the greening condition of the environment can be improved. The large amount of greenery and highly wetted surfaces, while creating a particular visual perception, can easily lead to improper and unregulated moisture, which can be a negative factor affecting the human living environment.

the plant selection refers to selecting plants with transpiration, the plants with transpiration selected in the embodiment are plants with leafiness, and the plants with specific transpiration selected by the green plant humidifying system with the self-regulating function are one plant or a plurality of plants which are planted in a mixed mode. Under the condition of a green plant humidifying system, when the air temperature is 20 ℃ and the relative humidity is 20%, the average transpiration rate M of the leaves is required to be more than or equal to 20 g.m-2·h-1. The average transpiration rate of leaves of a plant can be estimated by measuring the instantaneous transpiration rate of leaves at different positions in different time periods according to the following formula:

wherein M is the average transpiration rate g.m of the blades-2·h-1(ii) a e is the measured instantaneous transpiration rate mmol.m of the leaf-2·S-1(ii) a n is the number of measurements.
Further, secondary control is plant leaf size control, which means controlling the total initial leaf area of the selected plant and further controlling by trimming the plant. The selected plants in the green plant humidifying system are trimmed by controlling the total leaf area of the selected plants, so that the total leaf area in the green plant humidifying system is adapted to the humidifying requirement of the space in which the green plant humidifying system is located.
Therefore, under the condition of the green plant humidifying system, the numerical value of the plant leaf scale coefficient S is determined according to the condition of the average transpiration rate M of the leaves of the selected plant.

The total surface area of the leaves of the plants can be calculated by randomly counting the surface area of the leaves of the plants in a local range and then converting the total surface area of the leaves of the whole plants.
Further, the water supply regulation in the embodiment means that the total moisture evaporation capacity of the green plant humidifying system is regulated by controlling the mode and the quantity of water supply. Aiming at a specific space, under the condition that the total scale A of plant leaves in a green plant humidifying system is determined, the humidifying degree of the environment where the plant root system is located is adjusted by controlling water supply, and the total water transpiration of the green plant humidifying system can be adjusted and controlled on the basis of the average transpiration rate M value of the leaves; the wetting degree and the total sprinkling amount of the plant leaves can be adjusted by sprinkling water to the plant leaves and controlling the sprinkling speed and the sprinkling time, so that the water evaporation amount of the green plant humidifying system can be quickly adjusted. Through the water supply regulation, three-level control of air humidity can be realized.
Under the condition that the water absorption capacity of the root is balanced with the evaporation water capacity of the leaf surface, the water supply rate of the root can be estimated according to the following formula,

wherein W is the root water supply rate g.h-1(ii) a A is the total scale m of the plant leaves2(ii) a M is the average transpiration rate of the blades g.m-2·h-1(ii) a and a is the proportion of the transpiration water amount of the blades to the water supply amount of the roots.
In the case of complete evaporation, the leaf spray rate can be estimated as follows,

wherein W' is the average watering rate g.h-1(ii) a V is the volume m of the space where the green plant humidifying system is positioned3

It should be noted that, the green plant humidifying system with the self-regulating function can be designed by selecting plants, and by controlling the scale of the leaves, the selected plants in the green plant humidifying system can be trimmed, so that the total surface area of the leaves in the green plant humidifying system is adapted to the humidifying requirement of the space where the leaves are located, and secondary control of air humidity can be realized. The green plant humidifying system with the self-adjusting function in the embodiment can be provided with a humidity monitoring instrument and a water supply/sprinkling automatic control valve pipeline so as to realize the automatic control of three-level control of air humidity.
Aiming at the space condition that the air humidity needs to be regulated and controlled, the air humidification with the self-adjusting function can be realized while greening and beautifying the space through the green plant humidification system which is reasonably designed. For the space with little fluctuation of air humidity, the balance of moisture in the air can be realized by the design method of primary control and secondary control in the embodiment, and the stability of the air humidity is kept. For the space with large air humidity fluctuation, on the basis of the design of primary control and secondary control of the invention, the quick supplement of moisture in the air can be realized by a three-level control method, and the quick adjustment of the air humidity can be kept.
