Basic Electrical Engineering for HVAC Engineers
1. AC (alternating current) 2. DC (direct current) The selection of an energy source for equipment depends on its application, each having its own merits and demerits, but for an HVAC system or typical building services, we are concerned with AC voltage. Industrial AC voltage levels are roughly defined as LV (low voltage) and HV (high voltage) with
