Warnings on Lab-4 HVAC

Hello everyone,
A few announcements about spots in the Lab where you need to be careful.

1. We were discussing units for L-4 during the Sec-61. There's a typo in units for Emission RATE ECO2/V (both in the PDF and XLS Quest1 cell I13. The correct unit is ppm/(h*ppl) - makes sense to have 1/h for a rate. In the Sec-61 class we thought a typo was in I29, and we were wrong. I just corrected the BbLearn template, as of Thu 4/23 20:09.
2. If you like to make a unit analysis, remember that kwh is a jargon for kW*h, a unit of energy. My PECO bill also uses kWh, no multiplication operator inside!
3. EER is a Coefficient Of Performance, it compares Energy vs. Energy. In the industry it is often used unitless, but the 'unit' for it is BTU/(W*h) - Energy/Energy. Keep it in mind when you see it in the cell I20 of Quest2. You will need to use EER in your calcs!!! In addition to the Lab there's a good chance the Final Assessment will have a question about EER.
4. With that said simply follow the PDF instruction and you will get it done all correct.
5. BIG WARNING Quest3: in the columns answer what you are asked, read the columns' heading WORD-TO-WORD and answer what is asked there. The cost of a wrong answer there could be  easily 15 pts!

Good luck and remember you have ALL the data and parameters in the PDF, Quests' themselves ("Please determine ...") and the Gray Blocks.
