There are two components to a Mini-Split Heat Pump system. It has an outdoor compressor/condenser, and an indoor air-handling unit. The conduit of the Heat Pump houses the power cable, refrigerant tubing, suction tubing, and a condensate drain, links the outdoor and indoor units. The handling unit of the Heat Pump is connected to one outdoor unit. The number of unit Heat Pump units also depends on how much heating or cooling is required for the building or each zone.
