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.
