How to Achieve Efficient Dehumidification?

Our house is full of moisture due to wind, rain or other reasons. And we want to reasonably control the building humidity, in order to make our human living environment more comfortable, healthy and safe.

Dehumidification of buildings

It is a very troublesome process to control the relative humidity in the building correctly. This means that you may need to install a desiccant system in your building to ensure a dry indoor environment. At the same time, in humid climate, the building may be more humid. In addition to the dry type of building materials, dehumidification machines are also needed to keep the whole environment dry. This is very important for cities in the tropics.

For the use of compressor dehumidifier or desiccant dehumidifier is a very complex problem. There is no doubt that in order to save energy and energy consumption, keeping building walls dry can effectively save building materials and save a lot of maintenance costs. So when you buy a commercial dehumidifier, don't give up because of its price, because it will help you save more money.

Specific strategies for humidity control

1. Except for special circumstances, it is forbidden to use fossil fuel and electric power for humidification above 30% relative humidity and dehumidification below 60% relative humidity. And inside the building, you can also place some small desiccant dehumidifiers to help the building become dry and warm.

2. When a special building space needs to maintain a specific humidity, if at least 10% humidity is needed, then you need to put the dehumidifier in the indoor space. The frequency of dehumidifier is about once a week to protect the building and maintain humidity.

3. When setting a specific humidity level, the standard is that at least 75% of the thermal energy comes from the solar energy generated on site, and dehumidification control should be carried out regularly.

The above methods are helpful to create a more effective dehumidification system. However, they do not involve the type of the system itself. In this regard, in the past 20 years of research, by using a dedicated outdoor air system to separate heat and moisture energy, dehumidification can be effectively maximized.

In essence, dedicated outdoor space systems are designed to accurately manage air ventilation in buildings using 100% fresh outdoor air. These systems decouple the air conditioning process and deal with the ventilation and humidity energy and other energy separately. At the same time, the potential energy component of the system is usually one of two devices (or a combination of them). A cooling coil used to lower the air temperature, condense the water, or a desiccant wheel absorbs the water from the incoming air, all of which are to maximize the solution to the related problems.

The control of relative humidity is also regulated by law. This is because the relative humidity in the building has a great impact on health, safety and comfort. However, controlling humidity can take a lot of energy, which brings a lot of problems to architects trying to maximize sustainability. In addition, there is a lot of evidence that the best way to achieve efficient dehumidification of buildings is to use the relevant systems to deal with various energy consumption separately.
