Revision history [back]

Hi, guys! Since I asked a question and got solved last time, I learned a lot more about eneergyplus, but now i meet a new question and need your help. I try to expand the area of DOE Reference Retail Building and add a real HVAC system to simulate like a actual project. But i found the cooling load is very very low after simulation and figure out the reason. In Zone Sensible Cooling, the Calculated Design Load and User Design Load in one large zone is all zero, while other zones is normal. I think the low cooling load is because it didn't calculate this missing zone, but I don't know why it is missed (I check all settings before and is the same as other zones). Then I found that the User Design Air Flow of this zone is very high (41.513 m3/s). And I observe that there seems be a relationship between this value and Design Load per Area (the air flow rate is bigger, the Design Load per Area is lower, so maybe big air flow rate will cause low or even zero load?). Im sorry I cannot upload pict or file because I dont have enough points. Hope you can discuss with me and guide me how to solve it.
