Below is a small sample of our exam prep questions:

(1)  Using the duct size calculator provided, and based on the effect of compression of the flexible duct on the air flow efficiency, what would be the approximate CFM air quantity given the following variables?

      • 15% compression
      • 10-inch flexible duct
      • 0.1 friction loss.

ADI Duct Size Calculator – 200 CFM

(2)  Understanding the refrigerating effect of melting ice and changing state to water, calculate the amount to heat in BTUs given a five (5) pound block of ice that is frozen stable at 32 degrees F, and is to be heated to a hot temperature of 82 degrees F. How many BTUs would be required?          

Modern Refrigeration and Air Conditioning – “refrigerating effect of ice”. Steps to solve are shown below:

      • Step_1: Not a required step, as the block is not below freezing temperature of 32.
      • Step_2: BTU = Weight of Ice x Latent heat of fusion of Ice = 5 pounds x 144 BTUs/pound = 720 BTUs.
      • Step_3: BTU = Weight of Water x Specific Heat of Water x Temperature change = 5 pounds x 1.0 x 50 degrees F (82-32) = 250 BTUs.
      • Step_4: Finally, sum of the sub-totals = 720 + 250 = 970 BTUs

(3)  Incandescent lights produce a significant larger amount of heat than LED (light emitting diodes) lights. A 20 W LED produces 68 Btu/hr. How many Btu’s does a 100 W incandescent light produce per hour?

      • Modern Refrigeration and Air Conditioning 2017 – 50.1.2, Heat from Lights is 1 W = 3.41 Btu/hr. Therefore, calculate the load = 100-watt x 3.41 Btu/hr = 341 Btu per hour
