The Heating, Ventilation, Air Conditioning and Refrigeration (HVACR) Engineering Technology curriculum is a two-year, upper-division sequence leading to a bachelor of science degree. Instruction is aimed at developing expertise in system and controls design, retrofitting, testing and adjusting, system balancing and building operations with microcomputer controls. Students learn up-to-date methods of identifying and performing efficiency evaluations on different types of heating, ventilation and air conditioning systems found in commercial and industrial buildings. They also learn methods of adjusting and balancing equipment for maximum performance. In addition to classroom study, students perform energy and HVACR systems analysis for West Michigan businesses and industries. An energy systems laboratory includes equipment, computers and instrumentation found in commercial or industrial buildings. The lab includes a ten-ton variable air volume, four-zone system that controls cooling, heating and ventilation with computerized energy management. There also is a paid internship in the summer semester between the junior and senior year.
