This book contains the work which i carried out as my final year project, the main theme of the project was to design an air-conditioning system of a pharma products manufacturing area by using the design conditions as provided by the client. This design does not only focus on human comfort but also concentrates on the process comfort as Pharma Manufacturing is considered as a sensitive case. It helps me out in studying and researching of different topics and terms which i never studied before. The whole journey of completing the project will always be memorable for me as there were some ups and downs and i remember how i tackled with them. All in all Thanks to Almighty Allah for giving me the strength to complete the project and i pray for me and my fellow engineers for a better future ahead. Syed Muhammad Abdullah
