Box window wall units consist of a single package air conditioner that is installed through a wall or in a window space. Box window wall units achieve heating and cooling by a refrigeration process, using R32 refrigerant, where the cool coil extracts heat from the air and dissipates that heat into the air through the hot coil.
In cooling mode the cool coil is inside the home, and the hot coil is outside. In heating mode the hot coil is inside and the cool coil is outside. This is known as “reverse cycle” or “heat pump” heating and cooling.
