Design And Drafting of Hvac, Central Air Conditioning System For An Office Building

Abstract

The objective of this project is to design HVAC system for beverage industry. Firstly, the requirements and Design Basic Report (DBR) of the HVAC system are defined. DBR gives a clear picture of filtration level, required conditions, Cost-effectiveness, Energy conservation, Fire safety, Indoor air quality (IAQ) and Ease of maintenance. Air Flow diagram makes you understand the Air Handling Unit (AHU) zoning for the HVAC system. Beverage industry zoning areas include pulp cutting, blending and homogenizer, filler, anteroom, CIP room and pasteurization. Design calculation provides the data for recirculation and 100% fresh air supply and return system. Processing line is having sequence process rooms and each room have its own individual cooling load calculations. Design calculation gives the value of Tonnage of refrigerant, CFM and Dehumidification capacity of the system. Ducting layout issue the best routing for the site installation to distribute the air from the supply and return system. It includes the details of Damper, Ducting, Duct Insulation and Instrumentation to use in the facility. Supply and return system placement are also covered in this layout drawing and the Bill of Quantity is prepared.
