A split air conditioner is will generally have an indoor component (evaporator) and an outdoor component (condenser).
When the compressor runs, the evaporator will get cold and the condenser will get hot.
A heat pump also has a indoor and outdoor components, along with a new item called a reversing valve. The reversing valve allows the system to switch which component is the evaporator and which is the condenser.
When the compressor runs and the reversing valve is enabled, the evaporator is inside and you get cold air.
When the compressor runs and the reversing valve is disabled, the condenser is inside and you get hot air.
