Description
Technical field
The invention belongs to gas heater technical field more particularly to a kind of forced-ventilated gas water heater control methods.
Background technique
In northern area, winter cold is very long, and wind-force is generally larger, and night outdoor temperature is lower.Due to forced-ventilated gas
The smoke exhaust pipe of water heater leads to outdoor, and outdoor cold air is easy to enter in heat exchanger by smoke exhaust pipe.It is remaining in heat exchanger
Water freezes when being lower than 0 DEG C, leads to heat exchanger pipeline spalling.Existing gas heater is all largely anti-using electric heating
Freeze, electric heating assembly directly connects on the power line, control logic are as follows: a room temperature of connecting directly on electric heating part circuit is opened
The temperature controller on road, when the temperature of temperature controller drops to set temperature, temperature controller is connected electric heating assembly and is begun to warm up, and is heated to
The temperature of temperature controller disconnects temperature controller when rising to set temperature, electric heating assembly stops heating.Since electric heating assembly is obstructed
Master control borad control is crossed, is only controlled by temperature controller, user does not also know in the event of failure for electric heating assembly or temperature controller, only can be until heat
Just find that electrical heating antifreezing fails after the freezing house of hydrophone is soaked, the loss for causing user very big.In order to overcome these deficiencies, to strong
The control method of row's formula gas heater is developed.
