Abstract

UN APARATO DE ACONDICIONAMIENTO DE AIRE COMPRENDE UNA VALVULA (2) DE CONMUTACION PARA CAMBIAR LA DIRECCION DEL FLUJO DE REFRIGERANTE DESCARGADO DESDE UN COMPRESOR (1) PARA REALIZAR LA OPERACION DE ENFRIAMIENTO, LA OPERACION DE CALENTAMIENTO, O LA OPERACION DE ELIMINACION DE ESCARCHA; UN INTERCAMBIADOR DE CALOR (3) CON EL EXTERIOR PARA RECIBIR EL REFRIGERANTE ALIMENTADO POR EL COMPRESOR (1) A TRAVES DE LA VALVULA (2) DE CONMUTACION PARA REALIZAR EL INTERCAMBIO DE CALOR DEL REFRIGERANTE AL AIRE QUE RESULTA CALENTADO; UNA PUERTA DE ENTRADA (7) INTERCAMBIADORA DE CALOR REALIZANDO EL INTERCAMBIO DEL CALOR DEL REFRIGERANTE CON UN FLUIDO QUE RESULTA CALENTADO; UN SEPARADOR DE ACEITE (10) EL CUAL ESTA DISPUESTO EN EL LUGAR DE DESCARGA DEL REFRIGERANTE CONECTADA A LA VALVULA (2) DE CONMUTACION Y A LA PUERTA DE DESCARGA DEL COMPRESOR (1) PARA SEPARAR EL REFRIGERANTE Y EL ACEITE DE LA MAQUINA REFRIGERANTE LOS CUALES SON SEPARADOS DEL COMPRESOR (1); UN PRIMER Y UN SEGUNDO ACUMULADORES (9,13) LOS CUALES ESTAN CONECTADOS EN SERIE EN EL PUNTO DE ENTRADA DEL REFRIGERANTE EN LA PIPA CONECTANDO LA VALVULA (2) Y LA PUERTA DE ENTRADA DEL COMPRESOR (1); UN PRIMER PASO (11) DE DOS VIAS CONMUTADAS PARA CONECTAR EL SEPARADOR (10) DEL ACEITE Y EL SEGUNDO ACUMULADOR (13) A TRAVES DE UNA VALVULA SOLENOIDE (12); Y UN SEGUNDO PASO (14) DE DOBLE VIA CONMUTADA PARA CONECTAR EL SEPARADOR DE ACEITE (10) Y LA PUERTA DE ENTRADA DEL COMPRESOR (1) A TRAVES DE UN DISPOSITIVO (15) DE MEDIDA. COMO RESULTADO, EL ACEITE DE LA MAQUINA REFRIGERANTE VUELVE AL COMPRESOR (1) A TRAVES DEL PRIMER PASO (11) O DEL PRIMERO Y SEGUNDO PASOS (11,14) PARA PREVENIR QUE EL COMPRESOR (1) FALLE DEBIDO A LA ESCASEZ DEL ACEITE DE LA MAQUINA REFRIGERANTE.FIG 1.
