Abstract

UN ACONDICIONADOR DE AIRE EN QUE, CUANDO SE ACCIONA UN PRIMER COMPRESOR 1, 201 Y SE DETIENE UN SEGUNDO COMPRESOR 2, 202, EL LIQUIDO REFRIGERANTE NO FLUYE AL SEGUNDO COMPRESOR NI SIQUIERA EN UN ESTADO DE SUCCION DE VAPOR HUMEDO, NI TIENE LUGAR UN DESCENSO DEL ACEITE LUBRICANTE EN EL SEGUNDO COMPRESOR NI UN DESCENSO DE SU CONCENTRACION, NI TAMPOCO SE ROMPE EL SEGUNDO COMPRESOR DEBIDO A UNA LUBRICACION DEFECTUOSA CUANDO SE ARRANCA EL SEGUNDO COMPRESOR. EL ACONDICIONADOR DE AIRE NO CAE EN UNA ESCASEZ DE GASTO INUTIL LAS CAPACIDADES DE REFRIGERACION Y CALENTAMIENTO CUANDO EL ACONDICIONADOR DE AIRE NO SE ENCUENTRA EN UN ESTADO DE SUCCION DE VAPOR HUMEDO DEBIDO A QUE DETECTA BIEN LA PRESENCIA O AUSENCIA DEL ESTADO DE SUCCION DE VAPOR HUMEDO. EL PRIMER COMPRESOR Y EL SEGUNDO COMPRESOR SE ENCUENTRAN CONECTADOS ENTRE SI MEDIANTE UNA TUBERIA IGUALADORA 3, 203. HAY UN PASO DE COMUNICACION 28 QUE CONECTA UN TUBO DE DESCARGA 6 Y UN TUBO DE SUCCION 8 DEL SEGUNDO COMPRESOR 2 ENTRE SI.
