The advantage of cooling and heating with air conditioners:
The major advantage of a split air conditioner compared to a cooling or heating system is the complete independence with which a room can be cooled, while a second room is heated with the same system. This offers a lot of flexibility and efficiency in the use of the air conditioning.
During cooling, heat is extracted from the room. A system with heat recovery brings this absorbed heat to a distribution box where the heat is first usefully distributed to other rooms or even to the underfloor heating or hot water before being discharged outside, as with 'normal' split systems. This means that the heat energy initially remains "in the house" and is used optimally.
Despite the fact that the heating function of a split air conditioner performs just as well as an air/water heat pump, this aspect is rarely mentioned. This is remarkable, given the great potential of the heat pump in a split air conditioner to heat spaces efficiently.
It is important to mention that an air conditioning indoor unit must be installed in every room, which may result in the installation of air conditioning gutters. Although this is not always aesthetically pleasing, it does offer the possibility of efficient cooling and heating in different rooms.
All in all, a split air conditioner offers many advantages, such as the ability to cool and heat independently in different rooms, the efficient use of heat energy and the good performance of the heat pump. It is a versatile system that is definitely worth considering when choosing a cooling or heating system for a room.
