Abstract

Un horno de calentamiento de aire de gas quemado tiene un fuelle de suministro de aire modulable y una válvula de gas modulable conectada operativamente al quemador intercambiador de calor de aire de combustion. Una secuencia de calibracion de un sistema de control a base de microprocesador se utilizar para determinar automáticamente la relacion precisa entre el ajuste de la válvula de gas y el calor real transferido por intercambiador de calor al aire que fluye a través del horno por la medicion del aumento de la temperatura del aire real a través del intercambiador de calor obtenidos utilizando ajustes de calibracion inicial del fuelle y la válvula de gas. El microprocesador utiliza los resultados de su secuencia de calibracion para establecer una correlacion de ajuste entre los ajustes del fuelle y la válvula de gas, los cuales el microprocesador utiliza subsiguientemente para ajustar las velocidades de flujo del fuelle y la válvula de gas en un forma que mantiene un aumento de la temperatura del aire generalmente constante, predeterminada a través del intercambiador de calor, mientras que el horno altera su velocidad de salida de calentamiento de aire total en respuesta a las demandas de calentamiento de cambio del espacio acondicionado servido por el horno.
