Revision history [back]

Dear Everyone I am dealing with few energy models for LEED which contains Air Curtain. This device works only to prevent cold air infiltration when doors are open. Usualy I had one or two air curtains in a few store buildings so their energy use weren`t big comparing to whole energy use. In that case I modeled them using their maximum capacity and simple shedule ( 80% capacity in peak building load in winter time and 40% in other hours in building time operation). The problem exist in my new model - KFC restaurant. Air curtains using this schedule use too much energy - 2x more than central heating. It seems unrealistic and I have no idea how to model them accurately. I use the same technique for both Baseline and Proposed case. I use Carrier HAP software.

I am looking forward for any help
