I am an engineering student asked to do an airconditioner audit of a given site as a project. I visited the site, which is an office/lab/storage bldg, and have gathered some information such as the number of a/c units, type and the name plate readings of the units. Now, I would like to know what exactly is to be performed in an airconditioner audit. Any help would be greatly appreciated. I could give you more information but right now I just want a start.
