OBJECTIVE To study the factor of Indoor Air Quality specified for 300

beds hospital.

To design the filtration system for the system based onthe type of building project.

To determine the cooling load and design the coolingcapacity includes installation of system.

To master the e-Quest software simulation for design the

building.

To understand the ANSYS CFD simulation for betterunderstanding and getting the accurate result of realitycondition.

E-Quest LOADCALCULATION For the energy analysis, the e-Quest software is used to

determine the cooling load and cooling capacity on thesystems, it is a sophisticated, yet easy to use buildingenergy use analysis tool which provides professional-level

results with an affordable level of effort.

ANSYS CFD ANSYS FLUENT software contains the broad physical

modeling capabilities needed to model flow, turbulence,heat transfer, and reactions for industrial applicationsranging from air flow over an aircraft wing to combustionin a furnace, from bubble columns to oil platforms, fromblood flow to semiconductor manufacturing, and fromclean room design to wastewater treatment plants.

Special models that give the software the ability to modelin-cylinder combustion, aeroacoustics, turbomachinery,and multiphase systems have served to broaden itsreach.

CONCLUSION

Designing a HVAC system for a Hospital isnt an easy jobto do. We need to follow all the standard and requirementthat has been establish in order to achieve the correctdesign referring to the ventilation system, filtration,piping and etc. Most of them consume a lot of time and

concentration.
