Fan Coils are indoor air conditioning units for cooling and heating that are connected to a water circuit and serve as the system for transferring thermal energy within the building's spaces. Their operation is based on the forced circulation of air by a fan. With the help of the fan, heat is distributed in the space, unlike simple radiators that do so through convection.

The main advantages of using fan coils are:

• In combination with a heat pump, we can achieve heating and cooling with a single system.
• Increased efficiency in heating and cooling, even at very low or high temperatures.
• The electricity consumption is minimal and proportional to the speed of the fans.
• Easy installation.
• Ability for autonomy per air-conditioned space.
