Problems solved by technology

[0005] (1) When dehumidifying the condensing dehumidification system, the air temperature must drop below the dew point temperature, which requires the system to have a very low evaporation temperature, which will result in low system efficiency and increased energy consumption. The temperature needs to be lowered below 0°C, which may cause frosting on the evaporator
[0006] (2) The dehumidification of the solid dehumidification system will be accompanied by a large amount of heat of adsorption, which makes the fresh air temperature higher and the dehumidification performance lower; and after the solid dehumidification material is saturated with moisture, the existing solid dehumidification system cannot regenerate it, making the Decreased dehumidification performance of solid dehumidification system

Embodiment 1

[0049] Such as figure 1 and figure 2 As shown, this embodiment provides a dehumidification system for dehumidifying the fresh air introduced into the room, so as to achieve the purpose of dehumidifying buildings that need to be dehumidified. Specifically, the dehumidification system in this embodiment includes at least one air duct; wherein, the air duct includes: a solid dehumidification module 11 , a fresh air channel and a return air channel. Wherein, one end of the fresh air passage is provided with a fresh air inlet 121 for allowing cooled fresh air to enter the fresh air passage, and the other end is provided with a fresh air outlet 122 . One end of the return air channel is provided with a return air inlet 131 for allowing heated return air to enter the return air channel, and the other end is provided with a return air outlet 132 . Among them, the fresh air passage passes through the solid dehumidification module 11, so that the solid dehumidification module 11 perf...

Embodiment 2

[0059] This embodiment provides a dehumidification system. Compared with the previous embodiment, the dehumidification system in this embodiment further includes a refrigeration system, and there are at least two air ducts. Among them, the refrigeration system is connected to the fresh air inlet of the fresh air channel in each air duct, and is used to cool down the fresh air; the refrigeration system is connected to the return air inlet of the return air channel in each air duct, and is used to heat up the return air .

[0060] Preferably, if figure 1 and figure 2 As shown, the refrigeration system in this embodiment includes a compressor 21, a condenser 23, and an evaporator 22; wherein, the condenser 23 and the evaporator 22 are connected to the compressor 21, and the evaporator 22 communicates with the fresh air inlet 121 of the fresh air channel , used to cool down the fresh air; the condenser 22 communicates with the return air inlet 131 of the return air passage, and...

Embodiment 3

[0065] This embodiment provides a dehumidification system, compared with the above embodiment, such as image 3 As shown, the dehumidification system in this embodiment has two air ducts; one of the air ducts is the upper air duct 1, and the other air duct is the lower air duct 2.

[0066] Such as image 3 As shown, preferably, the fresh air passages, return air passages and solid dehumidification modules 11 in the upper air duct 1 and the lower air duct 2 are arranged correspondingly up and down. This embodiment is set in such a way that when the solid dehumidification module 11 in the upper air duct 1 dehumidifies the fresh air, the return air in the lower air duct 2 regenerates the solid dehumidification module in the lower air duct; When the solid dehumidification module dehumidifies fresh air, the return air in the upper air duct 1 regenerates the solid dehumidification module 11 in the upper air duct.

[0067] Preferably, the switching between the fresh air and return ...

Abstract

The invention discloses a dehumidification system and a dehumidification method. The dehumidification system is characterized by comprising at least one air way, wherein each air way comprises a solid dehumidification module, a fresh air channel and an air return channel. One end of the fresh air channel is provided with an air inlet for entering cooled fresh air into the fresh air channel, and the other end is provided with an air outlet; one end of the air return channel is provided with an air inlet for entering the heated returned air into the air return channel, and the other end is provided with an air outlet; the fresh air channel passes through the solid dehumidification module, so that the solid dehumidification module dehumidifies the fresh air flowing through the fresh air channel; and the air return module passes through the solid dehumidification module, so that the returned air flowing through the air return channel regenerates the solid dehumidification module. The invention is mainly used for providing the dehumidification system and the dehumidification method having good dehumidification performance and high dehumidification efficiency.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to the technical field of dehumidification, and in particular to a dehumidification system and a dehumidification method. Background technique [0002] Air relative humidity is a key factor affecting the production and living environment. Among them, when the relative air humidity exceeds 75%, the corrosion rate of machinery equipment and steel products tends to rise linearly, causing losses to production and material storage; in addition, people living in humid environments are prone to diseases such as arthritis. Therefore, air dehumidification has become an indispensable part in the control of humid industrial and living building environments. [0003] At present, the commonly used dehumidification systems mainly include condensation dehumidification systems or solid dehumidification systems. Among them, the condensing dehumidification system lowers the air temperature ...
