Humidity of Underground Space

Humidity in the underground space has always been a problem. This article will analyze the causes of moisture in the basement and the solution to solve this issue.

Basement moisture-proofing is all about removing excessive moisture from the air. There are mainly these reasons for the high moisture content in the basement air.

Low temperature

The temperature of basement walls and floors is generally lower. Especially during the rainy season, the humid air cannot be expelled quickly after entering the basement, and it will condense into droplets when it’s connected with the low-temperature walls or proofs. Hot and humid outdoor air that contacts the walls in spring and summer will also form droplets.

Rain infiltration

Rain’s dropping into the soil and building damages can also result in damp basements.

Groundwater infiltration

In areas where groundwater resources are abundant or buildings near rivers and lakes, the water on basement walls will seep. Basement walls and baseboards are buried in the ground and are exposed to moisture for long periods of time.

Desiccant is a relatively simple way to dehumidify the basement.

Installing floor heating is also an effective way to keep moisture out of the basement. But it affects the temperature in the basement.

A portable dehumidifier is much more convenient than the above two. However, its dehumidification area is rather small and it can be quite noisy. It also has an disadvantage that it requires to be emptied manually.

All of these common dehumidification methods can solve the problem of basement humidity in a certain and limited way. The most appropriate method of dehumidification is to use a fresh air dehumidification system. This system can cover the entire basement, and also dehumidify and ventilate according to the needs of different weather conditions. It also has the function of purifying air during dehumidification, so that air in the basement is fresh with the right humidity level.

The fresh air dehumidification system adopts desiccant rotors as core component. The desiccant rotors don't make much noise when working and they don't affect the ambient temperature.

Puresci is a company that focuses on desiccant rotors. The PSL series we developed is very suitable for a fresh air conditioning system. This series of rotors can dehumidify in a low-temperature environment and save energy consumption.
