Many people still associate air conditioners mainly with cooling during hot summer days. However, modern air conditioning systems are complete climate solutions that provide cooling, heating, dehumidification and air filtration.
How does an air conditioner work?
An air conditioner operates using a refrigeration cycle. Heat is absorbed from indoor air and transferred outside through a closed loop containing refrigerant.
The indoor unit extracts heat from the room while the outdoor unit releases it outside. Modern inverter technology continuously adjusts system performance to maintain stable temperatures and improve efficiency.
Cooling, heating and dehumidifying
Most modern systems include a heat pump function, allowing them to heat rooms efficiently during colder periods.
They also remove excess humidity from indoor air and filter dust and allergens, contributing to a healthier indoor environment.
Choosing the right capacity
- 2.5 kW – small bedroom or office
- 3.5 kW – living room or medium space
- 5.0 kW or more – large spaces or commercial rooms
Besides floor area, insulation level, window size and internal heat loads influence the required capacity.
Single split vs multi-split systems
A single split system connects one indoor unit to one outdoor unit and is typically used for a single room.
Multi-split systems allow multiple indoor units to connect to one outdoor unit, making them suitable for homes or small offices with several rooms.
Installation requirements
Air conditioning systems contain refrigerants and are therefore subject to the European F-gas regulation. Installation and maintenance must be carried out by certified refrigeration technicians.
Maintenance and performance
Regular maintenance ensures optimal efficiency and prevents performance loss. During professional servicing, filters, refrigerant circuits and electrical connections are inspected.
