Ventilation and dehumidification system and control method for villa basement

Abstract

The invention discloses a ventilation and dehumidification system for a villa basement and a method thereof. The ventilation and dehumidification system comprises a light well skylight, a light collecting column, a solar energy water-air heat collecting column, an unpowered air cap, a solar energy water storage tank, a fan and a dehumidifying pipeline system, wherein the light well skylight is arranged on a basement roof, the light collecting column is arranged on the basement roof, and the dehumidification pipeline system communicates with a basement and the basement roof; fixing glass is arranged on the lighting well skylight, and a hole is formed in the middle; the light collecting column is arranged above the hole, and the solar energy water-air heat collecting column is connected above the light collecting column; the air heat collecting column is a multilayer round column with good light transmission, the center of the air heat collecting column is a hollow round column, and water tanks, air boxes and heat collection coating vacuum tubes are sequentially arranged in the solar energy water-air heat collecting column from inside to outside; the diameters of the hole, the lightcollecting column and the solar energy water-air heat collecting column are the same with the diameter of the hollow cylinder; and the water tanks of the solar energy water-air heat collecting columnis connected with the solar water storage tank. The unpowered air cap is arranged above the hollow cylinder of the air heat collecting column. According to the ventilation and dehumidification system,the good ventilation and dehumidification functions of the villas basement are achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of ventilation and dehumidification, in particular to a ventilation and dehumidification system and a control method for a villa basement. 【Background technique】 [0002] In many areas of our country, the basements of villas that have been built are usually dark and humid without sunlight, and there are problems of poor ventilation and severe humidity in high temperature seasons, which affect the quality of life. To increase the living function of the basement, the problems of lighting, ventilation and dehumidification must be solved. [0003] Existing solutions are generally to arrange fixed glass and ventilation louvers daylight well skylights in the basement or to adopt ventilation windows. These methods and methods all use the thermal pressure formed by the temperature difference between indoor and outdoor, that is, the "chimney principle" to achieve ventilation and lighting. Although there are certai...

AI Technical Summary

Problems solved by technology

These methods and methods all use the thermal pressure formed by the temperature difference between indoor and outdoor, that is, the "chimney principle" to achieve ventilation and lighting. Although there are certain effects, there are problems such as waterproof, insufficient effective ventilation area, and insufficient air tightness. When the wind speed in the external environment is relatively high, it even forms a backflow phenomenon, which cannot effectively ventilate, and the dehumidification effect is not ideal, which does not meet the requirements of use.
