Ventilation Systems
AIR WASHER
Ventilation system is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature by humidification and air washers to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives.
The intentional introduction of outdoor air is usually categorized as either mechanical ventilation, natural ventilation, or hybrid ventilation.
A well-designed supply system will consist of an air inlet section, filters, heating and/or cooling equipment, a fan, ducts, and register/grilles for distributing the air within the work space. The filters, heating and/or cooling equipment and fan are often combined into a complete unit called an air house or air supply unit. If part of the air supplied by a system is recirculated, a RETURN system is used to bring the air back to the air house.
Exhaust ventilation systems are classified in two generic groups:
- The GENERAL exhaust system
- The LOCAL exhaust system.
The general exhaust system can be used for heat control and/or removal of contaminants generated in a space by flushing out a given space with large quantities of air. When used for heat control, the air may be tempered and recycled. When used for contaminant control (the dilution system), enough outdoor air must be mixed with the contaminant so that the average concentration is reduced to a safe level. The contaminated air is then typically discharged to the atmosphere. A supply system is usually used in conjunction with a general exhaust system to replace the air exhausted.
