S440, the room using pressure difference less than default threshold pressure are used as the second room.
Specifically, pressure difference to be more than to the room of default threshold pressure as behind the first room, pressure difference is less than pre-
If the room of threshold pressure is used as the second room.
S450, the sub-control valve opening in first room is controlled to be maximum and control second room point control valve
Close, control the pump work at total oral siphon in the room, carry out automatically cleaning.
Specifically, because the first room is the room that pressure difference is more than default threshold pressure, illustrating the pipeline in the first room
Block, single-chip microcomputer control blocks the water intaking valve and outlet valve standard-sized sheet of pipeline, the water intaking valve and outlet valve contract fully of remaining pipes.Control
Global cycle pump 303 processed is started working, it is necessary to illustrate, it is the circuit for placing the control system in ground heating system not simultaneously close off
Overload and pipeline pressure increase the infringement caused to pipeline each several part suddenly.As shown in figure 3, by the judgement to pressure difference,
Belong to the first room assuming that judged result is room 1, room 2, room 3, room 4 belong to the second room, therefore, control master control
Point control valve in valve 305 and room 1 is opened, and point control valve of point control valve in room 2, point control valve in room 3 and room 4 is closed

In the embodiment of the present invention, the room by the way that pressure difference to be less than to default threshold pressure controls institute as the second room
State the sub-control valve opening in the first room to close for maximum and control second room point control valve, control the room
Circulation pump work at total oral siphon starts automatically cleaning, when the pressure difference in first room decreases below the default pressure
During threshold value, automatically cleaning terminates.Self-cleaning purpose is realized by the valve opening for point control valve for controlling each room.
Example IV
Fig. 5 is a kind of flow chart of the clean method for ground heating system that the embodiment of the present invention four is provided.The present embodiment is upper
State and be optimized on the basis of embodiment, this method specifically includes following steps：
S510, the temperature for gathering each room.
Wherein, temperature sensor refers to that temperature can be experienced and is converted into the sensor of usable output signal, in each room
Temperature sensor is equipped with, temperature sensor is by each regional temperature information transmission to single-chip microcomputer.Exemplary, temperature sensor can
To be built up in apart from the position on one meter six or so of floor.
S520, judge whether the temperature reaches preset temperature threshold value, each room is carried out according to the judged result
Mark, temperature is reached the room of preset temperature threshold value, as the 3rd room, temperature is not up to the room of preset temperature threshold value
It is used as the 4th room.
Specifically, preset temperature threshold value is pre-sets according to the demand of user, the preset temperature threshold value can be 22 DEG C.
Each room is identified according to judged result, the room that temperature reaches preset temperature threshold value is labeled as the 3rd room, will
The room that temperature is not up to preset temperature threshold value is labeled as the 4th room.Exemplary, if the temperature in certain room is 16 DEG C, it is less than
22 DEG C of temperature threshold, then be labeled as the 4th room by the room；If the temperature in certain room is 26 DEG C, higher than 22 DEG C of temperature threshold,
The room is then labeled as the 3rd room.
S530, control reduce the water-carrying capacity of the 3rd room oral siphon, increase the current of the 4th room oral siphon
Amount.
Specifically, being the warm water less than 60 DEG C due to entering the water in room, the temperature in room and the water-carrying capacity of oral siphon are in
Positive correlation, the water-carrying capacity increase of oral siphon, the temperature in room increases, and the water-carrying capacity of oral siphon is reduced, the temperature reduction in room.Institute
So that control reduces the water-carrying capacity of the 3rd room oral siphon, reduces the temperature in the 3rd room to preset temperature threshold value, increases by the 4th room
Between oral siphon water-carrying capacity, improve the temperature in the 4th room to preset temperature threshold value.
In the embodiment of the present invention, by gathering the temperature in each room, and by the temperature in each room and preset temperature threshold
Value is compared, and temperature being reached to, temperature, as the 3rd room, is not up to preset temperature threshold value by the room of preset temperature threshold value
Room be used as the 4th room, control reduces the water-carrying capacity of the 3rd room oral siphon, increases the 4th room oral siphon
Water-carrying capacity.Solve and the problem of room temperature that subregion temperature control causes is uneven in temperature is unable in ground heating system, realize logical
Cross and control the inflow in each room that the temperature in each room is adjusted.
On the basis of above-mentioned technical proposal, " control reduces the water-carrying capacity of the 3rd room oral siphon, increases described the
The water-carrying capacity of four room oral siphons " can be optimized for " by reducing the aperture of the room point control valve, reducing the oral siphon
Water-carrying capacity；By increasing the aperture of the room point control valve, increase the water-carrying capacity of the oral siphon ".
Specifically, when temperature is not up to preset temperature threshold value, single-chip microcomputer controls the valve opening of the water intaking valve in the room
Increase or decrease the water-carrying capacity of oral siphon.When needing to increase the water-carrying capacity of oral siphon, the aperture of point control valve in adjustment room
To maximum, single-chip microcomputer process is closed when reaching preset temperature threshold value, until indoor temperature is improved to preset temperature threshold value；Work as needs
When reducing the water-carrying capacity of oral siphon, the aperture of point control valve in adjustment room is minimum, and monolithic is closed when reaching preset temperature threshold value
Machine stroke, until indoor temperature is reduced to preset temperature threshold value.The valve opening by controlling point control valve is realized come controlling stream
Speed, and then the purpose that temperature is adjusted.
Exemplary, in the effect of the circulating pump of each subscriber household water inlet, in addition to assisting to complete self-cleaning function,
It can also when needed be opened by control system, accelerate the flow velocity of hot water in ground heating system, realize the fast lifting of temperature.
