Hello All,

I am modeling engine driven chiller in eQUEST for multifamily residential building which has Natural Gas as fuel.
I have entered HIR at rated conditions into chiller property window in DD mode. Chiller is the only source for cooling in the model.
When i ran the simulation, i would get space cooling usage in winter months. I don't understand why am i getting space cooling during winter months.
Do anybody has any idea ?

Thanks,
Vipul
