Abstract

SE PRESENTA UN ACONDICIONADOR DE AIRE DEL TIPO DE LOS QUE TIENEN UNA BOMBA DE CALOR MULTICAMARA EN EL QUE SE CONECTAN UNA PLURALIDAD DE UNIDADES (2, 3, 4) PARA LAS HABITACIONES CONECTADAS A UNA UNIDAD DE FUENTE DE CALOR (1), LA REFRIGERACION Y EL CALENTAMIENTO PUEDEN EFECTUARSE SELECTIVAMENTE PARA CADA UNIDAD DE CADA HABITACION, Y PUEDE EFECTUARSE LA REFRIGERACION DE UNA HABITACION Y CALENTARSE DE FORMA SIMULTANEA OTRA, EN EL ACONDICIONADOR LA PRESION DE ALTO NIVEL O LA PRESION DE BAJO NIVEL SE CONTROLA DESDE UNA ALTURA DESCENDENTE SEGUN SE COMPARA CON EL TIEMPO DE FUNCIONAMIENTO NORMAL, MEJORANDOSE EL RENDIMIENTO DEL COMPRESOR (17). EN EL ACONDICIONADOR DE AIRE SE SUMINISTRA UN TERCER DETECTOR DE PRESION (48) PARA DETECTAR UNA ELEVACION EN LA PRESION ENTRE UN COMPRESOR (17) Y UNA VALVULA DE CAMBIO DE CUATRO VIAS (18), Y SE SUMINISTRA UN CIRCUITO DE CONTROL (49) PARA EFECTUAR UN CONTROL DE MANERA QUE, EN EL CASO DE QUE LA PRESION DENTRO DEL TUBO ESTE POR DEBAJO DE UN VALOR PREDETERMINADO, SE CIERREN UNA SEXTA (45) Y UNA SEPTIMA VALVULA (46), MIENTRAS QUE EN EL CASO DE QUE LA PRESION DENTRO DEL TUBO EXCEDA UN VALOR PREDETERMINADO, SE ABRAN LA SEXTA Y LA SEPTIMA VALVULA.
