Abstract

SE DESCRIBE UN SISTEMA DE REFRIGERACION QUE INCORPORA APARATOS PARA IMPEDIR EL SOBRECALENTAMIENTO DEL COMPRESOR (10,10'') ALIMENTANDO LIQUIDO REFRIGERANTE SELECTIVAMENTE DESDE LA SALIDA DEL CONDENSADOR (16,16'') AL COMPRESOR (10,10''). EN UNA VERSION EL FLUIDO REFRIGERANTE DESDE EL CONDENSADOR (16) SE INYECTA EN LA TOBERA DE SUCCION (52) DEL COMPRESOR (10). EN OTRA VERSION ESTE FLUIDO SE INYECTA DIRECTAMENTE EN LA CAMARA O CAMARAS DE COMPRESION (88,90). SE PROPORCIONAN MEDIOS DE CONTROL QUE INCLUYEN UN SENSOR DE TEMPERATURA (32,70,112) SITUADO DENTRO DE LA CAMARA DE DESCARGA DEL COMPRESOR (58,114) Y MEDIOS DE VALVULA (38,100,102) QUE RESPONDEN A ESTOS PARA CONTROLAR EL FLUJO DE LIQUIDO REFRIGERANTE A LA TOBERA DE SUCCION (52) O CAMARA DE COMPRESION (88,90).
