The modern commercial or office building consists of the HVAC system which is Heating, Ventilation, Air-conditioned. In this report, we’ll going to identify the purpose and goals of HVAC system, describe HVAC types, describe HVAC parts and describe how this part works together or its working cycle. outsides to air-conditioning there are ventilation systems like ceiling fan, fresh air supply and exhaust fan where ceiling fan is used is used to ventilate the air with rotating blades and exhaust fan is used to displace the inside air to the outside environment, fresh air supply is used to displace the inside air to the outside environment by supplying fresh air from the outside air. And also the design of duct by using the heat load calculations based on that how much amount of air to be carried out to gain the required cooling inside the area is determined and also creating the comfortable zone for the humans.
