[EnergyPlus_Support] Re: outside air temperature
Thank you , Dru,
Because I am testing a cooling mode for a certain equipment, I need
a fixed outdoor temperature 30DBC . Then can I use SummerDesignDay
in Day Type instead of WinterDesignDay to accomplish this task? OR
WinterDesignDay can handle any temperature I want, i.e, -10C or 30C?
"Whatever" means I can customize a value I like, does not it?
