Solar energy computer controller adopts existing product (as the product of Jiangsu sun rain company).
The intelligence control method of solar water heating system is as follows:
When A, initial normal condition, the sky shade motor does not start, not sunshade of sky shade;
B, manipulation solar energy computer controller are set time parameter:
At first be the selection and the setting of period classification: " the segmentation during date ", " segmentation during week ", " long-term formula of date ";
" the segmentation during date ", promptly in the middle of 1 year, control instruction from certain date to certain date (for example the specialty salesperson can help the user set the acquiescence duty according to regional climate characteristic--every year in such a month, and on such a day to which date, what cover in prop up thermal-collecting tubes);
" segmentation during week "; promptly in 7 days from the Monday to the Sunday, (for example, the user just comes to villa rustica each weekend the control instruction of some day or a few days; only need noon on noon Friday to Sunday and remove sky shade during this period of time, the same sunshade of other times is with the protection solar thermal collector).
" long-term formula of date ", the i.e. control instruction of set time in the middle of every day (for example, somewhere dust storm at night is big, may damage thermal-collecting tube, starts sky shade automatically in time in night every day to early morning and all hides solar thermal collector so set).
Next is to set at the start-stop hour: assigning to xx point xx minute from xx point xx needs sunshade during this period of time.
" startupoptions immediately ", i.e. sunshade immediately or remove the switch option of sky shade can't be carried out fixed cycle operator to sky shade.For example when suffering that suddenly hail attacks, the user starts sky shade immediately.
C, the thermal-collecting tube that needs are hidden hide the gear setting; The thermal-collecting tube quantity that set to need hides (as, can block the unit as one by per 5 thermal-collecting tubes, then the solar thermal collector of one 20 arm can be divided into 4 unit, stepper motor can 4 gears of relative set);
D, then sets the highest water temperature T 2max of water tank and minimum water temperature T 2min; Set temperature T 1 and the temperature difference numerical value Δ T=T1-T2=Y between the water tank water temperature T 2 (user can select numerical value Y between 5--20 degree centigrade) in the solar thermal collector; Affirmation also is provided with parameter more than the storage.
E, manipulation computer controller carry out automation control according to above setting:
At first, judge whether that according to the built-in time system of computer needs start sunshade function: when period and hour all meet setup parameter, electric motor starting, the thermal-collecting tube of covering set position quantity; Like this, by " period and hour " input instruction, sky shade is carried out timing, quantitatively control.
Then, identification and analysis temperature data: when T2＜T2min and difference DELTA T＜Y, electric motor starting removes sky shade; When T2 〉=T2max and difference DELTA T 〉=Y, electric motor starting hides whole heat collectors.
By the fully automatic operation of solar energy computer controller control solar water heating system, hardware support kit equipment such as parameter control circulating pump, magnetic valve and auxiliary electrical heating that can be default according to time and temperature etc.
Function of use one: the user can set that (the water tank maximum temperature value is big more by the computer controller to the water tank maximum temperature, the heat of storage is many more, but the water tank water temperature is too high not only dangerous but also scale easily, can allow the user freely select this water tank maximum temperature value between the 60-90 degree); When the water tank water temperature reaches the maximum temperature of setting, if the cause computer controller temperature in the solar thermal collector relatively again--temperature in the heat collector exceeds certain setting value (such as the temperature difference more than 10 degrees centigrade) than water tank water temperature, the supply that extraneous solar energy so just is described has obviously exceeded demand, and at this time the computer controller starts sky shade automatically and comes sunshade; If the temperature in the heat collector close with the water tank water temperature (such as the temperature difference in 10 degrees centigrade) even lower, then the solar energy in the explanation external world is not many especially, (distance of water tank and solar thermal collector is far away more to consider thermal loss in the heat transfer process again, the heat-insulating property of water pipe is low more, thermal loss is big more), just the overheated problem of water tank can not occur, also just there is no need to start the sunshade function of sky shade.
Same reason, the user can set the minimum (such as 50 degrees centigrade) of a water tank water temperature by the computer controller, dropped to when the water tank water temperature below the minimum temperature of this setting, this moment the computer controller to compare in the solar thermal collector temperature--if the temperature in the heat collector is less than certain setting value (such as 70 degrees centigrade), the supply that extraneous solar energy then is described is not enough really, should remove sky shade automatically, to enlarge collector power.
Function of use two: the computer controller is surveyed water tank and solar thermal collector temperature inside by temperature-sensing probe, and start some function according to temperature value, such as when being higher than 10 degrees centigrade of water tank water temperatures at the solar energy heating actuator temperature, automatically start water pump and realize heat exchange, with the water in the heating water tank; After the water tank water temperature reaches the maximum temperature of setting, stop pump working, (these functions are that the basic function that the pressure-bearing type solar heat water system all has is produced in the split on the market to stop solar thermal collector and water tank to carry out heat exchange.The developer of solar energy computer controller can increase expanding function according to client's needs).
In addition, the development angle of successively decreasing from technology innovation and production cost, single-chip microcomputer in the solar energy computer controller need be reserved USB or other I/O interfaces, connects the internet, and the user can be in case of emergency by digital terminal equipment networking straighforward operations such as Ji Suanji PDA or mobile phones; Perhaps entrust professional institution (such as the solar water heater after-sale service department) according to the weather condition Remote, hide heat collector such as remote control when attacked by hail or strong wind.Can also be connected solar energy computer controller with meteorological testers such as " automatic weather stations ", can obtain the folding that data such as wind and rain and solar radiation are controlled sky shade automatically by automatic weather station; Can also when raining heavily, open puggaree automatically, so that by rain-out cleaning puggaree surface.
