Abstract

Un acondicionador de aire (1) que comprende: un radiador (16) configurado para hacer que la radiación de calor se realice con respecto al aire de un refrigerante supercrítico durante la operación de calefacción; un ciclo de refrigeración que incluye el radiador; y un controlador (4) configurado para controlar la temperatura ambiente dentro de una habitación que es un objetivo de acondicionador de aire al causar una presión lateral de alta presión del ciclo de refrigeración que incluye el radiador (16) y una temperatura de salida de refrigerante del radiador (16) para alcanzar los valores objetivo respectivos que se han establecido de antemano, caracterizado por que: el controlador (4) está configurado para aumentar o disminuir el valor objetivo de la presión lateral de alta presión cuando se ha reconocido un exceso o una deficiencia de la capacidad de operación de calefacción por la temperatura ambiente a pesar de la presión lateral de alta presión y la temperatura de salida del refrigerante habiendo alcanzado los valores objetivo, y en el que el controlador (4) está configurado además para aumentar el valor objetivo de la presión lateral de alta presión cuando ha transcurrido una cantidad predeterminada de tiempo sin que la temperatura ambiente alcance una temperatura de ajuste.
