An air dehumidifier using plant root water absorption character

Abstract

An air dehumidifier using plant root water absorption character includes an air-dehumidification box and plants planted on the air dehumidification box. The air dehumidification box is divided into an upper space, a middle space and a lower space by an upper air grid plate and a lower air grid plate, a damp air inlet is provided at the upper part or upside of the upper space, and soilless culture substrate with an activated carbon structure is incorporated in the middle space between the two air grid plates, and a dry air outlet is provided at the lower part or lower side of the lower space. The plant is planted on the air dehumidification box in a state that the trunk of the plant perforates through the top board, upper space and the upper air grid plate of the air dehumidification box, and the root system part of the plant is entirely buried in the soilless culture substrates. This invention is an air dehumidifier which does not consume energy in the dehumidification side. Compared with the prior art, the invention not only saves a great amount of operating costs; but also further reduces other forms of environmental pollution due to its characteristics of no need of energy consumption.

Description

technical field [0001] The invention belongs to the technical fields of building environment and equipment engineering and heating, ventilation and air conditioning, and in particular relates to an air dehumidification device. Background technique [0002] In order to make the air quality in the building meet the hygienic requirements, it is necessary to deliver outdoor fresh air—fresh air—to the room. The summer outdoor air in hot and humid areas not only has a higher temperature, but also contains a large amount of water vapor. This kind of air with excessive moisture content will not only make people feel uncomfortable, but even be harmful to human health. Therefore, not only must the collected outdoor fresh air be cooled, but also dehumidified. [0003] As far as dehumidification technology is concerned, there are freezing dehumidification method, solid adsorption dehumidification method, liquid absorption dehumidification method and so on in the prior art. Although t...

AI Technical Summary

Problems solved by technology

For example, the dew point of freezing and dehumidification cannot reach low humidity due to the limitation of freezing water temperature, and the humidity control ability is limited, and the surface cooler of the freezing and dehumidification method is operated in wet conditions, which is easy to breed bacteria and viruses, resulting in a decline in indoor air quality

Solid adsorption dehumidification, the running process of the runner is dynamic, the mixing loss is large, the efficiency is low, and the latent heat released during the dehumidification process increases the temperature of the desiccant and reduces the moisture absorption capacity

The coefficient of performance of the dehumidifier and regenerator of liquid dehumidification is not high, and the physical properties of the dehumidification solution limit the further improvement of the system COP

In addition to their own characteristics, they also have a common shortcoming, that is, they all consume a lot of energy, which will cause another form of pollution to the environment.
