Solid dehumidifier

Abstract

The invention discloses a solid dehumidifier, comprising: an upper air duct and a lower air duct, solid dehumidification modules are arranged in the upper air duct and the lower air duct; a fresh air assembly, the upper air duct and the lower air duct are connected to the fresh air assembly; a return air assembly, the upper air duct and The lower air passages are also connected with the return air assembly; the wind direction switching device is arranged at the air outlet of the upper air passage and the lower air passage. The fresh air component communicates with the lower air duct and makes the return air component communicate with the upper air duct. Applying the technical solution of the present invention, the wind direction switching device is used to switch the air duct and change the flow direction of the wind field, so as to realize the switching between the fresh air and the return air in the two-layer air duct, and then realize that the fresh air is dehumidified by the solid dehumidification module and then sent into the indoor space. The return air regenerates the dehumidified solid dehumidification module and discharges it to the outdoor space, so as to achieve the purpose of improving dehumidification and regeneration efficiency.

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
