Wall mounted Heat Pump Air Condioner

It work in much the same way as your refrigerator, except there are two separate but integral parts to the system. There is an outside unit housing the compressor that is similar to the exterior back of your fridge. It draws warmth from the outside air in even the coldest of weather. That warmth is then transferred inside the home using a refrigerant process through a piping system powered by an indoor fan unit that is typically mounted to the wall. This is why the system is also often referred to as a heat pump rather then air conditioning. Both are in fact the same. Similarly, in summer the reverse happens. Warm air is drawn from the interior room and expelled by the outside unit.
