[TRNSYS-users] Cooling load calculation



Hello Everyone,

 

I have made a simple cooling load calculation model in TRNSYS v16 and similar setup in E-quest. There is vast variation in cooling load when I put into outdoor air in the room.

In TRNSYS I used 2800 sqft area building having 150 person occupancy and according to ASHRAE 62 (ventilation rate procedure) I calculated 1150 CFM outdoor air as fresh air. When I taking no outdoor air the cooling load is about 10 ton but when I put outdoor air through ventilation (2.46 ACH) the cooling load increases and reached at 42 ton.

 

And in E-quest it increase only 1 ton.

 Can anyone help me to find out the reason?

I attached bui. File and tpf file.

 

Regards

 

Mayank
