Abstract

HVAC systems used in living and industrial buildings should fulfil thermal comfort needs and indoor air quality.In Heating,Ventilation And Air conditioning (HVAC) sytem,there are two catogeries air conditioning system such as water cooled chiller and air cooled chiller used for building.Multiple systems can maintain greater comfort throughout the building while saving energy by allowing different zones of the buildings to be at different temperatures.The greatest savings come when a unit serving an unoccupied zone can be turned off. However now add zoning and think of how often that zone is being used and how much energy can be saved by turning off the heating and cooling to those zone when they are not being used.Without implementation of automatic damper in a HVAC system,the air will remain supplied to an unused room or an empty room.So,when this happen energy will be wastage.A trainer kit has been developed to investigate the problem.This energy waste can be reduced by using automatic damper.To achieve a better energy efficiency level,the motor blower fan must be controlled to make sure air flow rate for each room has occupant not affected when the damper is closed in unused rooms.Thus this study will focuses on the energy efficiency when using the automatic damper and controllable motor blower fan.Build 6 room and for size each room is 12in x 9in. Perspex is the material that will be used for build a trainer kit.Besides that,aluminium sheet metal also using for this trainer kit.The equipment used for build a trainer kit are Bending machine,Scissors Cutting aluminum sheets,perspex cutting blades.The data obtain will be nalyzed with the theoretically method.
