The circular flow of real-time traffic and circulation line control booster pump 208 is closed, wherein, circular flow is the normal stream of circulation line
Amount.So as to which the central hot water gas heater 200 can be utilized with the difference of hot water flow before and after 106 open and close of water spot to control
The start and stop of booster pump 208, realize the flame-out shutdown of water heater after the water of pass, realize Automatic-boosting hot water flow.
It should be noted that circular flow is the normal flow of circulation line, for a structure and the certain (example of connection relation
Such as duct length, pipe diameter size are certain) circulation line for, the normal flow of the circulation line be substantially it is certain, can
With by testing and calculating is obtained ahead of time.
Further, central hot water gas heater 200 at least has water-use model and i.e. two kinds of working statuses of heat pattern.
It is divided to two operating modes below, central hot water gas heater 200 is specifically described respectively：
1. water-use model
Controller 209 is additionally operable to be in water-use model and at least one water spot 106 in central hot water gas heater 200
In the state of opening, and real-time traffic meets to control booster pump 208 to start during relationship below with starting flow：
Q≦Q1,
Wherein, Q is real-time traffic, Q1To start flow.
That is, when user is opened with 106 hot water of water spot, when real-time traffic is less than or equal to opening for booster pump 208
Flow is moved, then controller 209 controls booster pump 208 to start, so as to be pressurized to hot water flow.
Controller 209 is additionally operable to be in water-use model in central hot water gas heater 200 and be in water spot 106 to close
In the state of, and real-time traffic meets to control booster pump 208 to close during relationship below with circular flow：
Q2-Δ≦Q≦Q2+ Δ,
Wherein, Q is real-time traffic, Q2For circular flow, Δ is circular flow regulated value.
It should be noted that circular flow regulated value obtains for pre-trial or calculate, its according to the difference of circulation line,
Accordingly it is adjusted.In addition, after booster pump 208 is closed, there is no water flow signal, central hot water combustion gas heat in Q=0, i.e. pipeline
Hydrophone 200 is flame-out to shut down, and supercharging terminates.
Controller 209 is additionally operable to after closed mode is switched to by opening with water spot 106, controls central hot water combustion gas
Water heater 200 switches to i.e. heat pattern by water-use model.It should be appreciated that terminated with water spot 106 in Guan Shuihou, water-use model, in
Centre hot water gas heater 200 is again introduced into i.e. heat pattern.
2. i.e. heat pattern
I.e. heat pattern is a kind of operating status of central hot water gas heater 200, and in such a mode, user opens any
Hot water can be used with water spot 106.
Controller 209 is additionally operable to start according to i.e. hot service condition, control booster pump 208.
That is, when central hot water gas heater 200 reaches i.e. hot service condition, controller 209 controls booster pump
208 start.Wherein, i.e., hot service condition is default service condition, it can be that the water temperature of foundation hot water is accordingly set, certainly
Can also be other specification or other set-up modes.
Controller 209 is additionally operable to be in i.e. heat pattern in central hot water gas heater 200 and be in water spot 106 to close
In the state of, and real-time traffic meets that the water in relationship below and circulation line reaches i.e. hot stop condition with circular flow
When control booster pump 208 close：
Q2-Δ≦Q≦Q2+ Δ,
Wherein, Q is real-time traffic, and Q2 is circular flow, and Δ is circular flow regulated value.
It should be noted that real-time traffic meets Q with circular flow2-Δ≦Q≦Q2+ Δ, central hot water gas heater
200 run heat pattern in sight, and when the water in circulation line reaches i.e. hot stop condition, controller 209 controls booster pump 208
Close.In addition, i.e. hot stop condition is default stop condition, it can be that the water temperature of foundation hot water is accordingly set, certainly
Can be other specification or other set-up modes.After booster pump 208 is closed, central hot water gas heater 200 is flame-out to shut down.
Controller 209 is additionally operable to be in i.e. heat pattern in central hot water gas heater 200 and be in water spot 106 to open
In the state of, and real-time traffic meets relationship below time control after supercharging with booster pump 208 with the hot water flow of water spot 106
Central hot water gas heater 200 processed is by being that heat pattern switches to water-use model：
Q3-δ≦Q≦Q3+ δ,
Wherein, Q is real-time traffic, Q3To use the hot water flow of water spot 106 after supercharging, δ is hot water flow regulated value.
It should be noted that hot water flow regulated value obtains for pre-trial or calculate, its according to the difference of circulation line,
Accordingly it is adjusted.In addition, unlatching is changed with real-time traffic Q during water spot 106 i.e. under heat pattern, work as Q3-δ≦Q≦Q3+δ
When, controller 209 controls central hot water gas heater 200 by being that heat pattern switches to water-use model.
In conclusion circulator 300 provided in this embodiment to water inlet due to that with booster pump 208, can play increasing
Pressure acts on, and lifts user's bathing experience, and need not set common water pump, reduces cost, and the circulator 300 is
One integrated modular construction, its is simple in structure, easy for installation, and in addition controller 209 can be according to flowing through water flow sensor
The startup and closing of the real-time traffic control booster pump 208 of 207 water, without manually starting booster pump 208, use is more square
Just, user experience is improved.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the present invention, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on, should be included within the scope of protection of this utility model.
