Abstract
Un procedimiento de control de un sistema de aire acondicionado (1) que tiene un modo de refrigeración y un modo de refrigeración libre, que comprende: el funcionamiento del sistema de aire acondicionado en el modo de refrigeración que incluye: la circulación de un fluido de trabajo (36) y un refrigerante (34) a través de un evaporador (28) del sistema de aire acondicionado en comunicación fluida separada con el fluido de trabajo y el refrigerante; la circulación del refrigerante a través de un compresor (12); y el puenteo de una bomba de refrigerante (20); la medida, por medio de un primer sensor de temperatura (16), de una primera temperatura de aire ambiente exterior a un condensador (18); la medida, por medio de un segundo sensor de temperatura (26), de una segunda temperatura de dicho fluido de trabajo que sale de dicho evaporador; el cálculo de una diferencia entre dichas temperaturas primera y segunda; la comparación de dicha diferencia con un valor predeterminado; la determinación de una capacidad de refrigeración disponible para el funcionamiento del sistema de aire acondicionado en el modo de refrigeración libre; el funcionamiento del sistema de aire acondicionado en el modo de refrigeración libre, que incluye el puenteo del compresor, si dicha diferencia es mayor que o igual a dicho valor predeterminado y el sistema de aire acondicionado tiene la capacidad de refrigeración disponible; y el funcionamiento del sistema de aire acondicionado en el modo de refrigeración si dicha diferencia es menor que dicho valor predeterminado o el sistema de aire acondicionado no tiene la capacidad de refrigeración disponible; y el seguimiento continuo de la primera temperatura y la segunda temperatura para el cálculo de la diferencia, usándose el cálculo como un factor en la conmutación del sistema de aire acondicionado entre los modos refrigeración libre y refrigeración.
