HVACR 401: HEAT PUMPS sets itself apart from other books on the market with its emphasis on the service technician perspective, instead of the design engineer viewpoint. The book begins with a review of the refrigeration cycle in comfort conditioning, and gradually progresses to more in-depth topics, including electrical schematics, maintenance, geothermal heat pumps, and troubleshooting case studies. With content that has been closely reviewed and revised in conjunction with the most respected national organizations in the HVACR industry (ACCA, PHCC, and RSES), this will prove to be a valuable learning tool that offers a wide range of critical concepts, presented in a clear, straightforward manner that facilitates comprehension and encourages you to apply the information as you learn it.
