The Effect of Fan Rear Circulation on Abnormal Overheating Protection after Shower Water Shutoff
This article mainly studies the effect of fan rear circulation on the overheating protection of plate-exchange gas-fired heating and hot water combi-boiler(hereinafter referred to as wall mounted boilers)after the shower water supply is cut off under abnormal conditions when the valves at the heating outlet and return outlet are closed.Experiments have shown that the wall mounted boiler,which operates according to the original fan rear circulation control logic,continuously increases the temperature of the extreme temperature controller and triggers machine overheating protection after the shower water is shut down.This article effectively reduces the maximum temperature of the extreme temperature controller after the water supply in the bathroom is stopped by adjusting the control logic of the fan rear circulation,and verifies the feasibility of the method through experiments.
