  The indoor fan of the unit drives air circulation within the room.

  During this process, indoor air flows through the air-conditioning evaporator, transferring heat to the refrigerant.

  The refrigerant is transported via system piping to the outdoor unit, where the condenser dissipates the heat into the outdoor environment.
