Proportioning valve in assembly 38 processed is adjusted to tolerance, so that leaving water temperature is consistent with design temperature.The hot water of generation is successively
By interior circulation hot-water line 37 and heat accumulation bucket water inlet pipe 32 be sent to inner bag 26, then water again from inner bag 17 to internal circulation pump 29 again
It is admitted to double pipe heat exchanger 44 to heat, until the temperature that water storage cylinder hygrosensor 30 is sensed in inner bag 26 reaches setting value
When, internal circulation pump 23 is shut down, and valve is closed, and stops burning.In the process, main controller 35 is carried out by each sensor
Monitoring, it is such as abnormal, then it can turn off source of the gas.
2) water state is used, water inlet manifold 15, total flow of inlet water sensor 16 and three-way pipe are passed sequentially through with cold water during water, always
Flow of inlet water sensor 16 is produced after signal, and internal circulation pump 23 does not start, and cold water is cold by being directly entered interior circulation after three-way pipe
Water pipe, enters back into after double pipe heat exchanger 44 is heated and enters inner bag 26.Water in inner bag 26 is then sent to by total hot-water outlet pipe 21
Use water spot.
In the process, main controller 35 is monitored by each sensor, such as abnormal, then can turn off source of the gas.
3) operation principle of heating
Whole heating system is a closed system, and when machine is in heating state, heating circulating pump 8 is started working, and is entered
Gas control assembly 39 opens air valve, under control of the controller 35, and whole combustion system is started working, and (now internal circulation pump is in and stopped
Only state).Water is drawn back by pump from fin sequentially enters heating return pipe 12 before pump, heating circulating pump 9, double pipe heat exchanger 44
After be heated, circulated again into radiator through heating outlet pipe 8.It is not up to when heating temperature detector 3 detects temperature
During design temperature, then whole heating system can continue great load and reach setting until heating temperature detector 3 detects temperature
During temperature, temperature-constant operation is done, in the process, internal circulation pump 23 is continued to run with, it is ensured that life water is flowing.But when user makes
During with starting insulation in domestic hot-water or water storage cylinder, then heating stops.
