Abstract

La modulacion de ancho del impulso se usa para controlar la velocidad de flujo a través de una válvula de solenoide de expansion en un sistema de refrigeracion. Un primer censor de temperatura está ubicado cerca de la entrada del evaporador, y un segundo censor de temperatura está dispuesto en un compartimiento que va a ser enfriado. Se incluye un controlador para controlar el ciclo de trabajo de la válvula de solenoide modulada por el ancho de pulsacion. El controlador recibe alimentaciones de los dos censores de temperatura, y controla el ciclo de trabajo de la válvula basándose en la diferencia de las dos temperaturas. El segundo censor de temperatura está ubicado preferiblemente en la pared posterior del compartimiento y puede estar adyacente a la entrada de aire del compartimiento, adyacente a la salida de aire del compartimiento, o entre la entrada de aire y la salida de aire.
