Abstract

La invención se refiere a un circuito mejorado para regular y controlar la presión de compresores de una disposición de aire acondicionado y a un métodopara regular dicha presión mediante dicho circuito. El circuito (200) es aplicable para control de la presión de descarga de compresores (120 A y B)para una disposición de aire acondicionado (100) multi-dividido con un ventilador unitario (115) instalado al aire libre, la disposición tienemúltiples compresores, (120 A y B) múltiples espiras evaporadoras (110), múltiples espiras condensadoras y un único ventilador instalado al aire libre.Los conjuntos de circuitos para la comparación (240) de las presiones, comparan las presiones de descarga de los compresores (120 A yB) con predeterminadosniveles de presión, de modo de generar una pluralidad de senales de estados de presión. El conjunto de circuitos de control (200) tiene entradas (210 A-B)para senales de encendido/apagado, y controla los estados de encendido/apagado de los compresores (120 A y B) de modo de generar una pluralidad de senales deestado de los compresores (120 A y B). El conjunto de circuitos (240) controla el ventilador (115) de acuerdo con ambos conjuntos de senales, en base a unesquema predeterminado de prioridades. El método comprende etapas de detección de presiones de descarga, comparación de presiones, se reaccionan senales deestados de compresiones y controlar el encendido y apagado.
