AHR 225 Commercial System Design

Lecture: 2 Lab: 3 Clinic: 0 Credits: 3

This course covers the principles of designing heating and cooling systems for commercial buildings. Emphasis is placed on commercial heat loss/gain calculations, applied psychrometrics, air-flow calculations, air distribution system design, and equipment selection. Upon completion, students should be able to calculate heat loss/gain, design and size air and water distribution systems, and select equipment.

Pre-requisite(s): AHR 211.
Course is typically offered in Spring.
Student Learning Outcomes (SLOs)
At completion of the course, the student should be able to do the following:

Calculate heat loss and heat gain for commercial structures according to ACCA Manual N.
Apply NC mechanical codes to commercial HVACR systems.
Determine proper heating and cooling equipment for building design loads according to ACCA Manual N.
Determine HTM for use in ACCA Manual N load calculations according to proper worksheets.
