Ilmastointi, commonly known as air conditioning, is a system designed to regulate the temperature and humidity of indoor spaces. Its primary function is to cool the air, but modern systems also often provide heating, ventilation, and air purification capabilities. The process typically involves a refrigeration cycle where a refrigerant is used to absorb heat from the indoor air and then release it outside.

The basic components of an air conditioning system include an evaporator coil, a compressor, a condenser coil, and an expansion valve. The evaporator coil is located inside the building, where it absorbs heat from the air passing over it. This cooled air is then circulated back into the room. The compressor then pressurizes the refrigerant, increasing its temperature. The hot refrigerant flows to the condenser coil, usually located outdoors, where it releases heat to the outside air. Finally, the expansion valve reduces the pressure of the refrigerant, cooling it down before it returns to the evaporator coil to repeat the cycle.

Air conditioning systems are vital for comfort in many climates, improving indoor air quality by filtering out dust, pollen, and other pollutants. They can also help to reduce humidity, which can prevent the growth of mold and mildew. The energy efficiency of air conditioning units has improved significantly over the years, with newer models consuming less electricity. Regular maintenance, such as cleaning filters and checking refrigerant levels, is crucial for optimal performance and longevity of the system.
