The closest thing to air conditioning that nature offers us.
Fan-coils are a type of heat or cold emitters that work with water as a heat transmission element, which end up emitting air for air conditioning. They consist of a battery or heat and cold exchanger.
The process is very simple, fan-coils use water as a refrigerant transmission element, that is, they receive hot or cold water from the aerothermal machine and recirculate it through internal tubes. Its fan drives air and passes it through the tubes where the water circulates, thus transferring its temperature. This air then passes through the room to be air-conditioned.
There are several types of fan-coils, some are anchored to the wall as if they were a traditional radiator and others are hidden on the false ceiling, distributing the air conditioning through grilles or diffusers.
