DLP-CH-T105: Word Document in the field of Central Heating Heating Theory & Heating Techniques Different Types of Ventilation

The document provides a brief description of ventilation and its different types. Ventilation is the process of bringing outdoor air into a building or room and distributing it within the space. Its primary purpose is to provide healthy air for people to breathe by diluting and removing pollutants.

The document identifies three basic elements of building ventilation:

Ventilation rate: The amount and quality of outdoor air provided to the space.

Airflow direction: The overall movement of air within the building, from clean zones to dirty zones.

Air distribution or airflow pattern: Efficient delivery of outdoor air to all parts of the space and effective removal of airborne pollutants generated within the space.

The document categorizes ventilation into five types:

Natural Ventilation: Relies on natural forces like wind and thermal buoyancy to drive outdoor air through openings in the building. Factors such as climate, human behavior, and building design influence its effectiveness.
