Heat Pump Air Flow Diagram

A versatile heating and cooling system a heat pump can both heat and cool a home by extracting heat energy from the surrounding environment and moving it to another location. Click back and forth between buttons 2 and 3 and note how the discharge from the compressor is diverted to different coils in each mode.
