Exhausting System

Proper design of the exhaust air system matching the supply air system can result in the following benefits:

 

 
 
 
A positive pressure workspace helps prevent the entry of dusts and particles.
 
An effective internal air flow pattern free of air short-circuiting.
 
An optimum air circulation through push-pull strategy that complements the supply and exhaust air systems
  For optimal evaporative cooling performance, a constantly ventilated environment is of key importance. This is particularly applicable to closed and semi-closed workplace design with harmful discharge from heavy duty equipment and machinery. The exhaust system works to maximize airflow circulation in such workplace by way of wall exhaust, roof exhaust or ducted exhaust. Exhaust air system forms a vital component of Open Space Cooling when the workspace is not open but semi-enclosed or enclosed. The supply air must be exhausted to satisfy the basic requirement of open space cooling in that, an air change is created and humidity build-up is controlled. Several exhaust air system approaches are available with each satisfying different workspace conditions. Different kinds of exhuast fans are suitable for different workspace environment  
 

Designing the exhaust system for maximum air change and optimal circulation for user comfort
Exhaust system's effectiveness highly depends on the type of exhaust outlets, 

the outlet size and location.
