1.2 TEMA DE LA ESTADÍA “Programa de Mantenimiento de Equipos del Hospital AIR ”
1.3 ANTECEDENTES Desde el principio de los tiempos, el hombre siempre ha sentido la necesidad de mantener sus equipos y maquinarias, aún las más rudimentarias herramientas o aparatos. La mayoría de las fallas que se experimentaban eran el resultado del abuso y la falta de conocimientos de los mismos y esto sigue sucediendo en la actualidad. Al principio solo se hacía mantenimiento cuando ya era imposible seguir usando el equipo. En el caso de la empresa donde se desarrolla la estadía, el Hospital AIR desde sus inicios se creó el departamento de Mantenimiento, esto con el objetivo de supervisar las áreas y las instalaciones de la empresa para brindar un servicio a cada uno de los elementos para que su funcionamiento sea de calidad y estén en optimas condiciones, sin embrago el área de mantenimiento solo ha realizado un mantenimiento correctivo, el cual se realiza en el momento de la falla es por eso que el proyecto de la estadía se apega a las necesidades del departamento, de llevar una organización y un desarrollo del mantenimiento a las instalaciones y en especial en el área de aires acondicionados, de esa manera agregar el mantenimiento preventivo ya que hasta el momento estos no se usan dentro del departamento.

CAPITULO II: MARCO TEÓRICO 2.1 COMPRESORES: FUNCIONAMIENTO Según Edward G. Pita en su libro “Principios y Sistemas de Refrigeración” la principal función de un
compresor de refrigeración es aumentar la presión de evaporación, hasta la presión a la cual el gas puede ser condensado. La función principal del compresor (el aumento de presión) produce algunas funciones secundarias, si bien son necesarias. La elevada presión de descarga proporciona la energía necesaria para hacer que el refrigerante circule a través de la tubería y del equipo, venciendo la resistencia de fricción. Además, el gran diferencial de presión creado motiva la expansión súbita en el dispositivo de control de flujo, causando una caída de temperatura. 2
2.2 COMPRESORES HERMÉTICOS El compresor de tipo hermético es aquel en el cual el compresor y el motor están integrados en un eje, y contenidos ambos en una caja sellada se llada a presión. Los compresores de tipo herméticos se fabrican ya sea completamente hermético o semihermético (también se les llama herméticos desarmables). El

2.3 SELLOS DE LOS COMPRESORES En los compresores abiertos, diseñados para operar a bajas velocidades, un empaque suave alrededor del eje constituía un sello apropiado para evitar fugas de gas. Los compresores modernos están diseñados para operar a altas velocidades, de modo que se necesita un compresor más pequeño para una capacidad dada, reduciéndose los costos. El empaque suave se desgastaría rápidamente trabajando en estas condiciones. Los sellos mecánicos se utilizan en todos los compresores modernos. La característica esencial estriba en que dos superficies duras, una estacionaria y otra en movimiento de rotación se ajustan apropiadamente para formar un sello a prueba de fugas. El sello rotatorio tiene un anillo de carbón fijo al eje; la superficie frontal de este anillo se mantiene en contacto contra un anillo estacionario, mediante un resorte. Existen otros diseños de sellos mecánicos, pero el sello rotatorio es uno de los más usados, debido a su bajo costo y confiabilidad. 4
2.4 VÁLVULAS En los compresores reciprocantes de refrigeración se utilizan dos tipos de válvulas de succión y descarga. Uno de ellos el tipo de aleta, de lengüeta o flexible. Consiste lámina delgada de acero

2.5 SISTEMA DE LUBRICACIÓN El sistema de lubricación del compresor puede ser del tipo de lubricación por chapoteo, de alimentación forzada o de una combinación de ambos. En el tipo de chapoteo, la biela tiene una cucharilla en su extremo inferior, la cual recoge aceite del carter y lo salpica en las superficies de desgaste. El sistema de alimentación forzada tiene una bomba de aceite que obliga al aceite a desplazarse hacia los cojinetes a través de orificios practicados en el cigüeñal. 6
2.6 ACCESORIOS Junto con el compresor, generalmente se ofrecen algunos accesorios para ser utilizados cuando sea necesario, los cuales se instalan por separado. Entre estos accesorios se encuentran:
Silenciadores. Se utilizan en las líneas de succión o descargar para disminuir el ruido que
producen las pulsaciones del gas. En el caso
de las pequeñas unidades herméticas,
invariablemente son parte integral de las m ismas.
Manómetros para medir la presión de succión, descarga y del aceite. Se utiliza para
comprobar el funcionamiento.
Resortes aisladores de la vibración. El compresor va montado en resortes, para disminuir las

2.7 FACTORES QUE AFECTAN EL FUNCIONAMIENTO DEL COMPRESOR Velocidad del compresor. La capacidad de un compresor se incrementa al aumentar su velocidad. Esta es la razón por la cual los compresores modernos se diseñan para trabajar a altas velocidades, de manera que se pueden utilizar compresores más pequeños. La potencia requerida aumenta con la velocidad de una proporción ligeramente mayor que la capacidad. Esto es, hay una ligera pérdida de la eficiencia de la energía a altas velocidades.
Presión de succión. La capacidad del compresor se reduce a medida que la presión de succión disminuye. Esto puede ser por dos razones. La primera es que al disminuir la presión aumenta el volumen especifico del gas el desplazamiento del compresor es constante; esto es, maneja un flujo volumétrico fijo de gas. El resultado es que el compresor maneja una cantidad menor de flujo másico del refrigerante, a un volumen específico más bajo, y por los tanto, disminuye la capacidad de refrigeración. El segundo efecto que tiene el cambio de presión de succión sobre la capacidad, lo ocasiona el gas a alta presión que permanece en el volumen de tolerancia. A presiones de succión más bajas, este gas se expande todavía más en la carrera de succión, acortando así el tiempo disponible para la admisión del nuevo gas.

2.8 EVAPORADOR: FUNCIONAMIENTO El evaporador constituye (junto con el condensador) un ejemplo del tipo de equipo conocido como cambiador de calor. Tiene como objetivo proveer una transferencia continúa y eficiente de calor desde el medio que desea enfriar puede ser un gas, un líquido, o un sólido. El aire y al agua son sustancias que comúnmente se enfrían con los evaporadores. El los evaporadores más comunes el refrigerante fluye por los tubos, mientras que el aire que se desea enfriar fluye por el exterior de los mismos. A estos tubos, construidos a menudos en forma de serpentines, se les llama la superficie de transferencia de calor. Por sencillez, la explicación que se presenta a continuación de la función del evaporador, se refiere a este dispositivo en particular. No obstante, es preciso enterarse de que existen muchas otras disposiciones y construcciones de evaporadores, y que el método de

Las superficies tubulares de transferencia de calor se pueden se pueden subclasificar de tubo liso y tubo con aletas. Se utilizan las aletas en los tubos o tuberías con el fin de aumentar el área superficial,
aumentando así la transferencia de calor por unidad de longitud de tubo. A la superficie comprometida por las aletas se le llama superficie secundaria, y a la superficie desprovista de aletas (tubo) se le llama superficie primaria.11

2.10 SERPENTÍN DE EXPANSIÓN DIRECTA Este tipo de evaporador se utiliza para enfriar el aire, tanto en el intervalo de temperaturas que cubre el aire acondicionado como para temperaturas más bajas. Se trata de evaporar el tipo de expansión seca, en el cual una mezcla de líquido y vapor se alimenta por los tubos, sin que haya recirculación de líquido. El dispositivo de control de flujo es por lo general una válvula de expansión termostática o tubo capilar. La forma más común es la de un serpentín plano, con tubos rectos y curvas de retorno, provisto del número requerido de hileras. Esta disposición se utiliza en unidades de manejo de aire que utilizan la convección forzada mediante un ventilador.13

2.12 FUNCIÓN Y OPERACIÓN DEL CONDENSADOR El objeto del condensador en el sistema de refrigeración es remover calor del vapor refrigerante que sale del compresor (o del generador en un sistema de absorción), de manera que el refrigerante se condense en su estado líquido. Entonces será capaz de lograr un efecto de refrigeración por evaporación. El condensador es un cambiador de calor, lo mismo que el evaporador. En el condensador, el calor se transfiere del refrigerante a un medio de enfriamiento, ya sea el aire o el agua. Como sucede en cualquier transferencia de calor, el medio enfriador debe estar a una temperatura más baja que el refrigerante.16

2.13 CONDENSADORES ENFRIADOS POR AIRE El condensador enfriado por aire generalmente se construye de tubos con aletas dispuestas en hileras de serpentines. El refrigerante fluye por los tubos y el aire fluye en dirección cruzada entre los mismos. Las aletas se utilizan debido al bajo coeficiente de transferencia de calor en el lado del aire. Los condensadores pequeños enfriados por aire, no tienen ventiladores, depende de la convección natural del aire caliente para que esta fluya. Se tiene como ejemplo el condensador utilizado a menudo en los refrigeradores domésticos. La tubería de los mismos se fabrica por lo común de acero, con aletas de alambre también de acero, cu yo costo es inferior al del cobre. 18 Se permita utilizar acero, debido a que a este condensador se le mantiene bajo techo, y no está sujeto
