select a building of your choice ( must be at least 4 wallsand one roof ) like library, office and etc....
assume any information that could help you ( loads, internalload, directions, people, etc....
1- calculate the hourly total cooling load (total, sensible& latent) using RTS method for a selected public space. Theload will be due to all types of external sources (solar, roof,exposed walls, Ventilation (fresh air requirement) infiltration(using ACH) & internal sources (occupant's, lights &equipment's).
2- calculate the required air volume flow rate (m3/s,CFM).
3- To calculate the cooling load required (TR) suitable forthe load calculated & to give a cost estimate for themachine.
