Hello everyone, today we are going to talk about an important topic in the ventilation system - why should we prevent condensation? Do you think that the ventilation system simply introduces fresh air into the home, and then everything is OK? In fact, there are many things to pay attention to!

First of all, the working principle of theventilation system is to filter and purify the outdoor air into the room, and at the same time discharge the dirty air indoors. During this process, if the cold outdoor air meets the warm indoor air, condensation will form on the contact surface.

Condensation may not sound like a big deal, but in fact, it is the “number one enemy” of your fresh air system!

Ⅰ The principle of condensation water generation

The main cause of condensation is when cooled solid surfaces (such as ventilation system pipes, equipment, etc.) come into contact with warm air, and the water vapor in the air condenses into water droplets on these cooled surfaces. This is especially common in ventilation systems, which need to continuously introduce cold outdoor air into the room. When the cold air meets the warm indoor air, condensation water is easily formed on the contact surface.

Ⅱ Hazards caused by condensation water

1. Equipment damage: If condensate water accumulates inside the pipes and equipment of the ventilation system for a long time, it may cause the equipment to rust and corrode, and even affect the normal operation of the equipment.

2. Deterioration of indoor environment: Condensed water may also seep from equipment or pipes and flow to indoor floors or walls, causing indoor moisture and mold, affecting indoor air quality and living environment.

Ⅲ Measures to prevent the generation of condensation water

1. Reasonable design and installation: When installing the ventilation system, ensure that the pipes and equipment have good insulation properties to reduce the direct contact between cold air and warm indoor air. For example, pipes can be wrapped with insulation to reduce heat loss and condensation.

2. Intelligent temperature adjustment: Some advanced fresh air systems are equipped with intelligent temperature control systems that can automatically adjust the air supply temperature according to the indoor and outdoor temperature difference to reduce the generation of condensation water.

3. Regular maintenance and inspection: Regular maintenance and inspection of the ventilation system timely discovery and treatment of condensation water accumulation problems, can effectively prevent damage to equipment and indoor environment caused by condensation water.
