The Air Conditioning Contractors of America says its heat pump manual gives HVAC contractors a one-stop reference guide for residential- and small-commercial heat pump systems. The 69-page book highlights basic principles, equipment, installation, operation, applications and system design with a series of step-by-step examples and design calculation.

Topics include: equipment selection, sizing and operating costs; air-to-air, water-to-air, air-to-water, water-to-water, fossil fuel hybrid, earth coupled and reclaim water loop equipment; multi-zone, split-coil heat pump systems; variable-air-volume heat pump systems; heat pump operating cycles and controls; efficiency descriptors; thermal and economic balance points; supplementary and emergency heat; heat sources and heat sinks.
