HVACR 122 Fundamentals of Load Calculations

This course introduces you to residential load calculations. This is a method to determine the heating and cooling Btu/h loads of structures prior to installing HVAC/R systems to meet those loads. The required text is the Air Conditioning Contractors of America (ACCA) Manual J, 8th Abridged Edition (MJ8-AE). The manual provides thorough instructions for estimating heat loss and heat gain for residential structures and helps to simplify complicated procedures that are often used on a variety of home applications. This course will provide instruction for completing load calculations by hand, which is necessary prior to attempting any computerized load program. We will focus on following the concepts of MJ8-AE while simplifying the methodology emphasized in the manual even further. We will utilize a “simple” residential structure and follow the steps to calculate both heat loss and heat gain for its location and outdoor design temperatures. We will also cover residential equipment selection focused on the heating and cooling equipment Btu/h loads of a structure. This course is shared in the following six modules:

• Module 1: Fundamentals of Load Calculations
• Module 2: Heat Loss of a Structure
• Module 3: Heat Gain of a Structure
• Module 4: Example Heat Loss and Heat Gain Calculation
• Module 5: Fundamentals of Equipment Selection
• Module 6: Regional Load Calculation Exercises
