In this video we will be learning how to calculate the cooling load for a cold room. We start at the basics first to understand the purpose of a cold room and then move on to understand the heat sources that form the cooling load and then we finish the video by using a worked example for a simplified cooling load calculation.

    Medium temperature refrigeration maintaining box temperature of 35 to 38F degrees have evaporator fan motors that run 24hrs per day when set point is satisfied and compressor is off to help defrost evaporator and for air circulation.

    Hey Paul,

    Could you do a video on residential load calcs and go more in depth on radiation heating. I'd love to learn more of the math and standards behind doing something similar to a manual J without dedicated software.

    Thanks for your informative videos!

    At the time stamp 5:48 your calculation for walls and roof are off. When you add up the walls and roof you get 118m sq not 113m sq. It is only a difference of .97Wh/d when you figure the equation. Would that small of a difference make any issues arise down the line?
