Abstract
METODO DE CONTROL DE LA PULSACION Y CAPACIDAD DE UN COMPRESOR CENTRIFUGO EN UN SISTEMA DE REFRIGERACION. CONSISTE EN DETECTAR LAS TEMPERATURAS DE CONDENSACION Y EVAPORACION DEL REFRIGERANTE CON SENDOS TERMISTORES (56 Y 58), GENERANDO AMBOS DOS SEÑALES DE LINEA QUE AL SER COMBINADAS EN UN AMPLIFICADOR DIFERENCIAL (59) PROPORCIONAN UNA NUEVA SEÑAL QUE ESTA RELACIONADA CON EL NUMERO DE MACH MINIMO MO PARA PALETAS DE AMPLIA ABERTURA (PRV). LA ABERTURA DE LAS PALETAS DEL COMPRESOR ES VARIADA EN FUNCION DE LOS VALORES QUE TOME EL NUMERO DE MACH MINIMO MO.
