Mechanical System For AL-Rehan Hospital Supervisor Students Dr. EYAD ASSAF Muhammad Shalan Muhammad Jitan JehaD Odeha JehaD Zuhd Objective The objective of this project is to design Conventional (HVAC) System (Fan coil units with chiller and Boiler ) for AL-Rehan Hospital. In addition with all recommended mechanical systems that should contain like (potable water, drainage, medical gases and fire fighting) systems. HVAC HVAC (heating, Ventilation, and Air conditioning) is the technology of indoor and automotive environmental comfort. HVAC system design is a major sub discipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Also the mechanical systems are to be introduced in our research including potable, drainage, firefighting and medical gases. Building Description Location Country: Palestine . City: Ramallah Region: Dahyet Al-Rehan. Elevation: 800 m above sea level. Latitude: 32 N. Wind’s speed in Ramallah is above 5 m/s. Al-Rehan Hospital consist of tenth floor ,four Basement Floor , Ground Floor and Five Up Floor and each Floor has approximately 1500 m^2 Inside and Outside Design Conditions Parameter Tin To Tun Tg Φin Φout Win Wout Winter 22 4.7 13 9.7 50% 70% 8.4 3.9 Summer 24 30 28 29 70% 52% 8.4 13.7 Overall Heat Transfer coefficient,Uoverall Overall heat transfer coefficient depends on the construction of the unit.
