Hi friends,

 

I am trying to model an Earth Air Tunnel (EAT) system that is being used in
a school for passive precooling.

During summer first the air is pre cooled using the EAT and then evaporative
cooling is done before being circulated into the zone.

During monsoon again precooling is done using EAT and then chillers are
being used for further cooling and dehumidification.

Does anyone have any idea as to how to calculate and incorporate the degree
of precooling that is achieved by the EAT into the eQuest model.

Any help would be greatly appreciated. Thanks
