Solid dehumidifier

Abstract

The invention discloses a solid dehumidifier which comprises an upper air flue, a lower air flue, a fresh air assembly, a return air assembly and a wind direction switch device. The upper air flue and the lower air flue are each internally provided with a solid dehumidifying module. The upper air flue and the lower air flue are connected with the return air assembly. The wind direction switch device is arranged on air openings of the upper air flue and the lower air flue. The wind direction switch device selectively enables the fresh air assembly to be communicated with the upper air flue or the lower air flue and enables the return air assembly to be communicated with the lower air flue or the upper air flue correspondingly. By the adoption of the technical scheme, air flue switch is achieved through the wind direction switch device, and the wind field flow direction is changed, so that fresh air and return air are switched in the two air flues, then fresh air is fed into the indoor space after being dehumidified through the solid dehumidifying module, the return air is exhausted to the outdoor space after carrying out regeneration on the dehumidified solid dehumidifying module, and the purpose of improving dehumidifying and regeneration efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a solid dehumidifier. Background technique [0002] Most of the solid dehumidifiers currently on the market use the dehumidification method of the rotary wheel. The rotary dehumidifier is mainly composed of a rotary wheel, a regenerative heater and a regenerative fan. The rotary wheel is made of a glass fiber board filled with special metals. It is rolled into a honeycomb-shaped round wheel, and then impregnated with silicate moisture-absorbing agent by means of advanced technology. [0003] The solid dehumidifier in the prior art generally makes the runner rotate slowly at a speed of 30 revolutions per hour. After the humid air to be treated is filtered by the air filter, it enters the honeycomb channel of the 3 / 4 runner, so the moisture in the air Dry air passing through the rotor is sent into the room for silicate absorption. While the runner absorbs moisture, part ...

AI Technical Summary

Problems solved by technology

[0005] 1. The volume is large and requires a high installation space;

[0006] 2. The weight of the runner is heavy, and the required drive motor power is high, which directly affects the efficiency and energy efficiency of the whole machine;

[0007] 3. There is radiation heat in the dehumidification and regeneration process, which directly affects the dehumidification and regeneration efficiency
