ГАЗОРЕГУЛИРУЮЩИЙ МОДУЛЬ

Устройство для регулирования потока газа, которое обеспечивает простоту обслуживания, производимого вручную. В частности, включение и выключение производятся одним движением. Для этого на корпусе расположен соединенный с электронным контроллером микровыключатель, который переключается при производимом вручную перемещении толкателя, расположенного по оси предохранительного клапана зажигания и основного клапана. В результате электронный контроллер получает электрический сигнал, вследствие чего при выключенном состоянии устройства для регулирования потока газа происходит его активация и тем самым зажигание потока газа, идущего через открытый предохранительный клапан зажигания, тогда как в уже включенном состоянии устройства для регулирования потока газа, напротив, происходит прерывание тока удержания, идущего на термоэлектрический клапан предохранителя зажигания, и тем самым дезактивация устройства для регулирования потока газа. Устройство для регулирования потока газа пригодно для зажигания ...

APPARATUS FOR REGULATING HEATER CYCLES TO IMPROVE FORCED-AIR HEATING SYSTEM EFFICIENCY

A method and apparatus of regulating cycles of a burner in a forced air heating system. A control unit uses a sensor at an output of a heat exchanger to make measurements of a temperature of air output from the heat exchanger. The control unit observes temperature measurements, after the burner has turned on. It initializes a confirmation interval when two consecutive temperature measurements are the same, if the temperature is the same at an end of the confirmation interval. The invention interrupts firing of the burner for an interrupt interval. The interrupt interval is insufficient to allow the heat exchanger to cool below a temperature useful for heating below which the circulation fan would shut off.
