Description
Technical field
Novel energy-conserving anti-freeze solar hot water technical field.
Background technology
For psychro-environment solar water heating system, novel energy-conserving anti-freeze solar hot-water heating system is adjusted for present general temperature difference cyclic control system, changes timing, two kinds of controls of the temperature difference into; Improve heat collector with the high potential difference of heat storage water tank, the water of realizing collecting system down time is emptying smoothly.Circulating line, valve, circulating pump are optimized to layout, make not need or use heating tape on a small quantity and reach the antifreeze object of winter solar energy hot-water heating system.﹙ water tank does not need to lay emptying, heat accumulation automation at Ban Re Dai ﹚ solar water heating system night when indoor, makes solar water heating system be easier to the utilization and extention in market, has achieved solar water heating system and has not been afraid of the mythology freezing.
Along with solar energy is developed rapidly by people as clean energy resource, the utilization of solar water heating system is more and more extensive, traditional temperature difference forced circulation, direct air system are not that special requirement water tank has the discrepancy in elevation with heat collector, as long as connecting pipe, start circulating pump, just can under the sun, produce hot water.Antifreeze aspect winter starting low-temperature circulating, heating tape protection.Just operation seems good, but to after 2 or three years, the aging frost crack pipe of heating tape, electric energy expends in a large number, and people just find the failure of this solar water heating system, and energy-conserving product is not energy-conservation.For this present situation, the invention solves this problem, will greatly promote popularization and the utilization of this energy-conserving product of solar energy
.
Summary of the invention
For present market solar water heating system do not consider to save electric energy use heating tape antifreeze, expend heat energy pump circulation anti-freezing, and the best combination of not considering energy-conservation, thermal effect and building structure, blindly pursue the muddled construction status of benefit, the present invention is intended to solve not consuming energy, the antifreeze problem of solar water heating system under psychro-environment under not power consumption condition, solves the problem that matches with building and can increase the solar water heating system thermal efficiency.
The following technical scheme of the invention process realizes.
Overall plan is: adjust the control mode of solar thermal collection system, temp .-differential circulation is timing temperature difference loop control pattern; Heat collector is higher than storage tank certain distance, makes under solar thermal collector circulating line higher than cistern water level, utilizes nature emptying or force the antifreeze of emptying solution solar energy system and the problem that improves thermal-arrest thermal effect.
One, solar water heating system is modified, temp .-differential circulation is timing temperature difference loop control pattern.Adjust the control system of solar thermal collection system: traditional control system is temperature difference circulation, in system, be full of working-medium water, when heat storage water tank 13 forms a fixed difference difference with the sensor temperature of heat collector 14, start circulating pump, high-temperature water is headed into heat storage water tank 13 from heat collector, water at low temperature fills into heat collector 14, the thermal-arrest circulation of the heat collector that so moved in circles.Novel energy-conserving anti-freeze solar hot water device, the emptying system start by set date circulating pump while moving for morning, makes after system fills with water, to stop circulating pump, forwards temperature difference circulation pattern to.
When solar water heating system moves under special low temperature environment in the winter time, utilize emptying technology, the water of collecting system is under Action of Gravity Field, because heat storage water tank 13 cannot enter heat storage water tank 13 by total reflux with heat collector 14 discrepancy in elevation are little, now needing to start row's control pump 10, can setting-up time be 18: 50.﹙ is at heat collector during higher than the certain high potential difference of water tank, and thermal-arrest circulating line can be emptying smoothly, and the row's of establishing control pump 10 ﹚ do not pump into water tank by not emptying hot water, now stop circulating pump, and shut electromagnetic valve 5, can setting-up time be 19: 30.Arranging startup, the time out of service of control pump 10 will determine according to solar energy system water, and the model power that row's control pump 10 adopts is without too large, and the happy pump of German prestige of take is example, and PH-041E is just adaptive.The startup of row's control pump 10 also can adopt water flow switch to control, and after water total reflux is complete, water flow switch is closed automatically, and row's control pump 10 is out of service.Night, or daytime, outdoor temperature is lower than five degree, and temperature controller starts heating tape K.Because there is probe sensor malfunctioning, heating tape aging phenomenon, causes heating tape not start, and causes circulating pump and pipe fitting bursting by freezing thereof.We establish a heating tape L antifreeze while being no more than 2 mitron road more, and often opened its winter, with frost-cracking-preventing, reach dual antifreeze.When electricity failure at night; Can open valve 6, the antifreeze section of tubing water of heating tape is emptying.When daytime, solar energy system moved, have a power failure and surpass 5 hours, temperature, below 0 degree, can be opened valve 8, water in solar energy system flows to into heat storage water tank next time at Action of Gravity Field, close water outlet main valve valve 7, open emptying valve 6, emptying lower than the remaining water in water tank section of tubing.The draining of general emptying valve 6 is connected to roof drainage pipe nearby, in order to avoid flooring winter skids because of drained water from freezing.During detail design, heat storage water tank requires larger 2/10ths than initial design volume, to meet night solar energy system hot water return, stores.
Two,, in conjunction with building structure, construction aspect improves the height of heat collector as far as possible, makes it higher than heat storage water tank.If building structure is not suitable for, with angle bar or channel-section steel welding production platform, solar thermal collector is installed, make heat collector higher than heat storage water tank.The general heat collector of ﹙ is installed between water tank, elevator roofing, or heat storage water tank is placed in to index bed Ding Ceng ﹚.
Change storage tank with the discrepancy in elevation of heat collector: traditional solar water heating system, because environmental factor storage tank is with the not very requirement of the heat collector discrepancy in elevation, has heat collector higher than heat storage water tank, also have lower than water tank.Our novel energy-conserving anti-freeze solar hot-water heating system requires heat collector higher than water tank certain distance, make under solar thermal collector circulating line higher than cistern water level, and pipeline water outlet is to be not less than 1% gradient output, backwater returns to be not less than 1% gradient, make working-medium water in heat collecting and circulating system in thermal-arrest circulation end every day, all reflux and enter heat storage water tank.In construction, forbid to return slope, to prevent pipeline internal water accumulation, the winter low temperature weather spalling pipeline that freezes, causes unnecessary loss.
Inner circulating tube water supply line adopts the gradient descending output that is not less than 2%, reflux line refluxes to be not less than the mode of 2% the gradient, in output and input circulating line minimum point, establish threeway and add drain solenoid valve 2, the other air bleeding valve 3 of setting up of circulating pump, if emptying drain valve 6, in order to the remaining water of power failure emptying pipe.Water tank is when indoor, and interior circulation does not generally need antifreeze, need to establish heating tape antifreeze when outdoor, and temperature controller is controlled.General be antifreezely no more than 2 meters, should adopt and lay two meters of heating tapes, a temperature controller is controlled automatically, a manual control, and often open winter, reaches dual antifreeze.Be most market as user needs twenty four hours supplying hot water, must utilize cold-starting internal circulation pump to reach indoor water supply in 24 hours one of hot water effluent's pipeline set temperature sensor, internal recycle pipeline does not need to lay heating tape.In winter, circulating water supply system should adopt Timing water supply, regularly opens magnetic valve 2 emptying pipe waters night, prevents frost crack pipe.Water supply pipeline needs ribbon heater antifreeze at outdoor section, the same two heating tapes, the identical control mode of laying.
Three, summer, outdoor temperature was high, did not need to consider antifreeze problem, and the most energy-conservation mode is temperature difference loop control.This system comes controlled circulation pump to circulate by the water temperature of the heat collector port of export and the temperature difference of water tank bottom.When two place's temperature difference are lower than setting value, circulating pump stops, and when two place's temperature difference are higher than setting value, circulating pump starts, and the high-temperature water in heat collector is headed into heat storage water tank, and the water temperature of heat collector slowly reduces, and when the temperature difference is less than setting value, circulating pump stops.So go round and begin again, reach the object that solar water heating system is produced hot water.Night, the sun set, and regularly opened magnetic valve 5, and the hot water return of solar energy system increases thermal water utilization efficiency.When morning, the sun rose, start by set date circulating pump 11, till its system water is filled with, stops circulating pump 11, starts temperature difference circulation.Pay special attention to, heat storage water tank delivery port need be installed ball-and-seat, prevents that heat collector is emptying when having a power failure, excess Temperature, and circulating pump starts again, causes vacuum tube to burst.﹙ Ru figure Suo Shi ﹚
Circulating line, valve, circulating pump, magnetic valve are optimized and are laid, increase two-way bypass pipe, make it be beneficial to solar water heating system emptying smoothly, reduce once can not emptying pipeline section as far as possible, cancel or use less heating tape antifreeze, resolutely refuse to follow with pump that ring is anti-freezes ﹙ water tank lower than heat collector one deck, and be placed in indoorly, can cancel companion's heat band ﹚.
