A recent engineering graduate working in the HVAC&R industry. This is an excellent course for anyone who needs a general overview of the principles of heat transfer and heating and cooling load calculation. Most plug loads operate at a fraction of their nameplate electrical load, so, as a result, produce significantly less heat load than engineers may use in their cooling load calculations based on those nameplate values, continues Friedman. by Brianna Crandall May 18, 2015The growing use of plug loads in buildings as well as insufficient data on how much energy they generate present a challenge to engineers and facilities managers in determining how to best cool a building, according to global building technology society ASHRAE. The updated values of typical heat gains. Chapter 18 of the ASHRAE Handbook Fundamentals, can give you some good directions for the calculations.
