hi everyone: I have been puzzled that increased energy consumption due to changing zone max supply temprature.for example. there are 3 months(12/1/2)heating at 95F(zone max supply temprature),but ony one month when at 88F. in my opinion, value of supply air temp just to be used to determin air flow. which will lead to changing in fan energy consumption. and from the sim file, I also see the alteration of capacity of heating device. maybe this change lead to a smaller heating load. but i don't understand how it do? who can give me some explain for this. any words will be appreciated. thans!
