MECHANICAL SYSTEMS OF AL-OYOON HOSPITAL-NABLUS

Abstract

Al-oyoon  hospital, north of Nablus, located at the top of  the north mountain at Nablus-Aseera street. The hospital has four departments A,B,C and D. In this project, only the mechanical systems of department A and C are calculated , A and C department has four stores , each on has an area more than 2000 m2. In this project, there is many mechanical systems was designed, like: 1-      HVAC systems (heating, cooling, ventilation, fresh air, exhaust are systems). 2-      Potable water system (hot water supply and return, cold water supply). 3-      Drainage system. 4-      Venting system. 5-      Fire fighting system. 6-      Medical gases system.   HVAC SYSTEM:   Select inside design condition (Temperature, relative humidity).  Select outside design condition (Temperature, relative humidity). Select unconditioned temperature. Find over all heat transfer coefficient Uo for wall, ceiling, floor, door, windows, below grade.  Find area of wall, ceiling, floor, door, windows, below grade. Find Qs conduction. Find V inf , V vent  .  Find Qs, QL vent, inf. Find Q domestic hot water.  Find Q total and Q boiler.   The heating load calculation begins with the determination of heat loss through a variety of building envelope components and situations. 1-  Walls 2-  Roofs 3- Windows 4- Doors 5_ Basement Walls Basement Floors 6_ Infiltration Ventilation
