Abstract

Un procedimiento para controlar una pluralidad de máquinas frigoríficas (2) de un sistema de climatización (1) que comprende medios de convección (3) conectados a las máquinas frigoríficas (2) a través de un circuito de servicio (4), que comprende un conducto de suministro (5) dentro del cual el fluido de servicio fluye desde las máquinas frigoríficas (2) hasta los medios de convección (3), un conducto de retorno (6) dentro del cual el fluido de servicio fluye en sentido contrario y un conducto de desviación (9) que conecta un punto (5a) del conducto de suministro (5) y un punto (6a) del conducto de retorno (6); estando caracterizado el procedimiento porque comprende: - medir, mediante medios de detección de temperatura (12-14), una primera temperatura (TDLV) del fluido de servicio en el conducto de suministro (5) aguas arriba del conducto de desviación (9), una segunda temperatura (TRET) del fluido de servicio en el conducto de retorno (6), y una tercera temperatura (TLIN) del fluido de servicio en el conducto de suministro (5) aguas abajo del conducto de desviación (9); - determinar una estimación de la carga térmica (PLE) del circuito de servicio (4) en función de dichas primera, segunda y tercera temperaturas (TDLV, TRET, TLIN); - determinar estados de funcionamiento (STi) y relaciones de carga parcial (PLRi) a fijar para las máquinas frigoríficas (2) para permitir que las máquinas frigoríficas (2) proporcionen una capacidad de enfriamiento global que satisfaga la carga térmica estimada con un consumo mínimo de potencia eléctrica; y - controlar el encendido y el funcionamiento de carga parcial de las máquinas frigoríficas (2) en función de los estados de funcionamiento (STi) respectivos y las relaciones de carga parcial (PLRi).
