122 HVAC/R Systems Load Calculations

122 HVAC/R Systems Load Calculations

Credits: 18
Estimated Length: 18 hour(s)
Due: 60 day(s) from enrollment date.

You will need the required text: ACCA Manual J, 8th Abridged Edition (MJ8-AE). This 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. Course 122 provides instruction for completing load calculations by hand, which is necessary before attempting any computerized load program. We focus on following the concepts of MJ8-AE while further simplifying the methodology emphasized in the manual. Students 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. This course also covers residential equipment selection focused on the heating and cooling equipment Btu/h loads of a structure. This course is recognized for 18 hours of continuing education (CEHs) applicable to NATE recertification.
