Abstract

Una instalación de refrigeración de compresores múltiples en que los compresores están conectados en paralelo para retirar vapor de agente frigorífico desde un manantial de aspiración común, caracterizada por la mejora que comprende un sistema de control de la presión de aspiración para regular el funcionamiento cíclico de conexión .desconexión de dichos compresores, incluyendo medios de interruptores que responden a la presión y que tienen ajustes de alta y baja presión previamente seleccionados para poner en marcha y detener los compresores en un orden sucesivo previamente determinado, con el fin de mantener la presión de aspiración en el sistema dentro de un margen previamente determinado, y medios de acción retardada que conectan los medios de interruptores de presión con el manantial de aspiración, comprendiendo medios restrictores para restringir la circulación de agente frigorífico y retardar una comunicación concomitante con presión de vapor desde el manantial de aspiración a los medios de interruptores de presión y medios de circulación unidireccionales para proporcionar circulación no restringida de agente frigorífico y comunicación concomitante con presión de vapor desde los medios de interruptores de presión al manantial de aspiración.
