Selecting Ventilation System in Comfort Environments

A quick selection guide of ventilation system in comfort environments

The cooling capacity of an air-condition system is often determinant for selecting the type and the principle,  and the capacity is often limited by comfort requirements.

Maximum capacities for displacement and mixing systems in different kind of buildings are roughly indicated below.

The heat load in typical rooms are influenced by the use of lights, heat emission from machines like computers, the number of people and the sun radiation through windows and other building elements. The heat load is typically very dynamic and for larger building and systems some kind of computerized tools are helpful in the designing process.

Heat loads in some typical rooms are indicated below:  

Typical rooms and heat loadsHeat Load
(W/m2)
Normal offices without automatic 0 - 30
Normal offices with automatic 30 - 50
Conference rooms 20 - 75
Data rooms > 60
Guest rooms, normal standard 0 - 25
Guest rooms, high standard 25 - 50
Patients rooms 0 - 20
Treatment rooms 20 - 60
Intensive rooms > 50
Conference rooms 20 - 75
Theater, cinema 40 - 60
Restaurants 30 - 70
Class rooms 20 - 50
Food 20 - 40
Normal 30 - 60
