This is a 2-hour long lecture-lab combination class. Some of the time will be spent lecturing using academic course materials. The rest of the time will be spent in a lab setting practicing the application of skills learned in theory. This class covers installation practices, energy auditing, and heating loss/gain on structures. The class will discuss and calculate load on forced air heating and cooling systems and determine required equipment for specific buildings. The course includes classroom, homework, and some computer lab and building location work. Study will encompass the age-old questions. How big is big enough? How does one properly determine heating and cooling system size? With the energy efficient equipment that is available to us today in the HVAC industry, there comes the responsibility to size the equipment to the building energy loss or gain. Why size it correctly? Customer comfort, equipment life span, and trouble-free energy efficient performance are a few of the many good reasons. This course will provide a working knowledge of the basics necessary to see HVAC system installation from sizing, planning and layout, selecting equipment, material list, to the completed balanced forced air system. This class may require participation in several field trips for further understanding of the profession. Prerequisites: 1st year curriculum in HVAC/R or equivalent and REFG 231.(S)
