Thank you to everyone that posted a reply to my question! It looks like I'll be spending a little more time with my ASHRAE books than I first thought.
Does anyone know where I can get a Psychometric Wheel? I've always used a chart because time usually isn't a factor like during the test.
Thanks again.
I believe most states require all reference material brought into the examination room to be "permanently bound." No loose items are permitted, but items secured in a three-ring binder (no opening of the rings of course) are okay. (Check your state for exact rules.) I'm not sure how this will work with the wheel...
Print out the ASHRAE Psych. Chart #1 on 11x17" paper and work your practice problems using that. You will have sufficient time to solve psychrometric problems using this type of chart on the actual test.
