Abstract

Se describe un método para controlar una unidad de eyector de capacidad variable (7) dispuesta en un sistema de refrigeración (1). Se genera una señal de control de eyector para la unidad de eyector (7) con base en una temperatura obtenida y una presión obtenida de refrigerante que deja un intercambiador de calor que rechaza calor (3), o sobre la base de una señal de control de válvula de alta presión para controlar un grado de apertura de una válvula de alta presión (6) dispuesta fluidamente en paralelo con la unidad de eyector (7). La señal de control de eyector indica si la capacidad de la unidad de eyector (7) debe aumentar, disminuir o mantenerse. La capacidad de la unidad de eyector (7) es controlada de conformidad con la señal de control de eyector generada. Se reduce el consumo de energía del sistema de refrigeración (1), mientras la presión del refrigerante que deja el intercambiador de calor que rechaza calor (3) se mantiene en un nivel aceptable.
