The invention relates to a method in which, in order to cool an air mass inside an enclosure having no walls and an inlet and outlet for air, the following steps are performed: moving the air mass by creating an airflow that passes through the entire enclosure, from the inlet to the outlet, so as to sweep the entire surface thereof increasing the time during which the airflow remains inside the enclosure by adding a twisting motion to the stream of air inside the enclosure in order to cause the airflow to move in a spiral inside the enclosure injecting a stream of water into the airflow moving in a spiral inside the enclosure, the entirety of said stream evaporating into the airflow, not only a portion thereof, while the airflow is inside the enclosure optimising water consumption according to the temperature, using a controller of the pumping unit spraying water, which is ejected under pressure through the opening of a nozzle that is small enough to form drops, the size of which 5 microns to 10 microns, causing the descending moist airflow, with the expansion model thereof, to come into contact with the animals in the stable and to cool said animals.Para enfriar una masa de aire se encuentra en un recinto sin paredes, con una entrada y salida del aire, se procede a - desplazar la masa de aire al provocar una corriente de aire que cruza todo el alojamiento desde la entrada hasta la salida, barriendo toda la superficie aumentar del tiempo de permanencia de la corriente de aire en el alojamiento por la introducción de un movimiento de torsión en el flujo de aire dentro del alojamiento para provocar que la corriente de aire se mueva en forma de espiral dentro de dicho alojamiento - inyectar un flujo de agua en el corriente de aire que se mueve en forma de espiral dentro del alojamiento, evaporándose la totalidad de dicho flujo en la corriente de aire y no parte, mientras que la corriente de aire se encuentra en el alojamiento - optimizar el consumo de agua en función d
