Temperature；When using first, need test along journey thermal loss data for using later；First by not up to heating-up temperature TPlusWater
Body enters storage tank, and when the first temperature sensor detects water temperature initial heating temperature T is reachedPlusWhen, water outlet of water heater stops row
Enter storage tank and arrange to water spot, remember that the moment is the 1st second initial time, now level sensor record water level h1；Take per second
It is analyzed by the water body of outlet pipe, it is T that setting water heater heating-up temperature is permanentPlus, detected the 1st second with water spot temperature sensor and arrived
Up to being T with the water temperature of water spotPlus 1, the water temperature of the 2nd second arrival water spot is TWith 2, the water temperature of the 3rd second arrival water spot is TWith 3, i-th
The second water temperature of arrival water spot is TUse i, and detection data is passed to into processor unit, processor unit is public according to heat Calculation
Formula Q=cm Δ T calculates the thermal loss of water body per second, as：
cmTPlus=Δ Q1+cmTWith 1
cmTPlus=Δ Q2+cmTWith 2
cmTPlus=Δ Q3+cmTWith 3
…
cmTPlus=Δ Qi+cmTUse i
As Δ QiWhen=0, TPlus=TWith, record data group：ΔQ1, Δ Q2, Δ Q3..., Δ Qi；
S2. operational phase：After primary data determines, begin to use water heater, water heater working, water outlet to start to warm up, first will
Not up to initial heating temperature TPlus 1Water body enter storage tank, reach initial heating when the first temperature sensor detects water temperature
Temperature TPlus 1When, water outlet of water heater stops entering storage tank and arranging to water spot, remembers the moment for initial time, now record storage
Water in Water Tanks position H1；
ΔQiThe thermal loss of water body per second corresponding equal to i-th second, processor unit is according to this data again by heat Calculation formula
Q=cm Δs T is calculated using i-th second heating-up temperature T during water heaterPlus i：
cmTPlus 1=Δ Q1+cmTWith
cmTPlus 2=Δ Q2+cmTWith
cmTPlus 3=Δ Q3+cmTWith
…
cmTPlus i=Δ Qi+cmTWith
Thus, can cause to use coolant-temperature gage TWithNot by being affected along journey thermal loss, keep constant with coolant-temperature gage；
Water temperature and data on flows in i-th second hot water pipe is detected respectively with temperature sensor at water spot and flow transducer, is transmitted
To processor unit, mixed water temperature T when processor unit is calculated i-th second according to heat Calculation formulaMixed i：
cmIt is mixedTMixed i=cmHeatTWith+cmIt is cold`TIt is cold`
mIt is mixed=mHeat+mIt is cold`
If now level sensor is detected and have in storage tank cold water, preferentially using cold water in storage tank, processor unit control
Controlling the water circulation pump is mixed into cold water in hot-water line, increases cold water flow Δ qStorage, flow-control at simultaneous processor unit control cold water pipe
Valve reduces cold water flow, reduces cold water flow Δ qIt is cold, Δ qStorage=Δ qIt is coldIt is scaled Water quality per second to be：
mStorage=mIt is cold`-mIt is cold
S3. empty stage：When water heater is stopped using, processor unit receives and is with the data on flows of water spot flow transducer
Zero, processor unit control pump working, water body in emptying outlet conduit, this part water body enters storage tank, so that next time mixes
Use during water.
8. it is according to claim 7 it is a kind of emptying cold water constant temperature and pressure hot water control device control method, its feature
It is, in step S3, when water heater is stopped using, everywhere with second temperature sensor detection water temperature data at water spot
TIn real time, processor unit will T everywhereIn real timeWith TWithDiffer from, take absolute value, i.e., | TWith-TIn real time|；If at least existed at one with water spot |
TWith-TIn real time| less than limit value, then the time inner treater unit is not emptied to outlet conduit, and water heater can fill in pipeline
Task again in the environment of full hot water；If respectively used at water spot | TWith-TIn real time| limit value is all higher than, then processor unit enters row
The empty stage；Wherein limit value be with the acceptable maximum fluctuation temperature difference of user under coolant-temperature gage, user can by processor unit from
Row is adjusted.
9. it is according to claim 7 it is a kind of emptying cold water constant temperature and pressure hot water control device control method, its feature
It is that storage tank inside clear height is L, L ＞ MAX { h2、H1、H2, i.e., storage tank inside clear height L must be more than h2、H1、H2Three
Maximum.
10. it is according to claim 9 it is a kind of emptying cold water constant temperature and pressure hot water control device control method, its feature
It is that, when level sensor detects water level H more than safety level, system stops to storage tank water-filling, now storage tank is only
Can water outlet, can not intake；The safety level is adjusted by user by processor unit.
