答复: [EnergyPlus_Support] air con ditioning load





but the room is on the 2nd floor, and the room below is not using air conditioner.

 

Should I still set outside condition as ground.

 

Regards,

 

Joey

Floor slab against ground should have boundry condition set to ground, not outside. Outside surfaces are exposed to sun and wind. 

 

Try that.

Hi everyone,

I`ve got a problem while calculating air conditioning load for a typical building.
Generally, the problem is when I set 'outside boundary condition' of roof and floor from 'surface' to 'outdoor' AC load of winter increases as expected. However,the AC load of summer decreases other than 'increase'. After all, while all set 'outdoor', AC load of winter is larger than that of summer. This is very wired. Can anybody explain for me? Or there is something wrong with my configuration. Thanks very much!

Joey
