Description

A kind of brand-new displacement heat exchange solar water heater
Technical field
The utility model relates to a kind of efficient Fast heating water temp to predetermined temperature, the separated type solar water heater that utilizes automatically controlled energy replacement hot water through cold water itself to store in the memory-type attemperater.
Background technology
Along with people's is to the more and more attention of environmental protection cause; The popularity rate of solar water heater is also increasingly high, but some shortcomings and shortcoming have in use also progressively appearred in solar water heater, greatly influence the enthusiasm that people use solar water heater; Solar water heater such as present family expenses; Because two big parts in the solar water heater system, heat collector and memory-type water tank adopt parallel architecture, and promptly heat collector has two pipes to be connected with inner water tank; No matter therefore use in what season, just at first need fill it up with water tank to cold water.Shine through shining of the sun then, utilize Natural Circulation to come the water in the slow heating water tank; The part solar water heater adopts two circulations, is exactly the medium that adds in the heat collector beyond dewatering, and heat medium through the water in the built-in heat exchange body heat-exchanging water tank in the water tank, reduces collecting efficiency and brings potential safety hazard.And the water temperature in the water tank is not controlled, implication, and the water temperature in the summer water tank might reach 100 degree, and winter, water temperature then possibly have only the twenty or thirty degree.
Can design a kind of solar water heater of brand-new heat exchange mode; Fully rely on the self-energy of running water to realize heating fast and heat exchange, and the temperature of the hot water in water tank can be according to requirements set, whatsoever season; As long as behind the design temperature; Water temperature in the water tank just keeps this temperature, simultaneously whole the setting conveniently succinctly, and system installs simple and reliable.System's water does not adopt other any medium, and it is antifreeze that the while also solves explosion-proof winter in summer.
Summary of the invention
A kind of brand-new displacement heat exchange solar water heater is invented in order to overcome the above problems, and the utility model solves the technical scheme that its technical problem adopted and is: whole system comprises memory-type attemperater, heat collector, controller, magnetic valve, level sensor or altitude valve, cooling-water temperature sensor and connects the pipeline and the connecting line of each several part; Heat collector and memory-type attemperater adopt method connected in series, and flowing through and flow in the heat collector earlier behind the magnetic valve in the water route, in heat collector, is heated to predetermined temperature; Controller detects water temperature to predetermined value, starts the respective electrical magnet valve, makes running water flow into heat collector once more; Pressure through running water itself is replaced already heated hot water in the heat collector in the memory-type attemperater; After displacement was accomplished, controller detected water temperature and is lower than predetermined value, closes corresponding solenoid valve; The cold water of newly coming in only can be in heat collector, till so back and forth the hot water in the memory-type attemperater is filled it up with.That is to say that the solar water heater system of the utility model, heat collector are after being heated to design temperature to the low capacity running water, just to replace hot water in the water tank, continue this process and fill hot water up to water tank, the hot water temperature in the water tank be confirm controlled; Rather than picture solar water heater in the market, pile water tank to cold water earlier, through heat collector slowly heating again, the thermal efficiency is low then, and the hot water in the water tank is uncontrollable.The heat exchange of the solar water heater system of the utility model mainly is to realize through the hot water in the cold water displacement heat collector; And the kinetic energy of displacement comes from the pressure of running water itself; Through controller control magnetic valve; The speed of this displacement heat exchange is very quick, considerably beyond the speed of water tank Natural Circulation heat exchange.After hot water had been expired in the water tank, this replacement process stopped at once.
Wherein the memory-type attemperater is a kind of non-press-bearing water tank, has shell, heat-insulation layer, inner bag to constitute, and has water inlet, delivery port, ventilation mouth, auxiliary electrical heating gate, and level sensor and cooling-water temperature sensor.The memory-type attemperater is a separate component, and is easier for installation rationally with respect to the roof solar water heater of integral type, and it is outdoor better than being placed on to be placed on indoor then heat insulation effect.And the volume of water tank, horizontal selection of still placing vertically are convenient.Other satellite interface is left as required in the water tank.
Wherein heat collector can be the heat collector that vacuum tube and header constitute, and also can be flat-plate collector; Heat collector has cold water inlet, hot water outlet; Near the inner hot water outlet of heat collector, place a temperature sensor; The electric satellite interface that also has with electric assistant heating has air emptying function, also has an interface that exhaust-valve is installed at corresponding site.This heat collector can pressure-bearing also pressure-bearing not, the pressure-bearing heat collector has different with the control magnetic valve process of non-pressure-bearing heat collector on controller.Because heat collector is mounted in outdoor; Need to consider heat collector local antifreeze in cold, the present invention's correspondence heat collector and relevant connection pipeline antifreeze is for the heat collector with header structure; Two kinds of designs are arranged; The first then starts electric heater through auxiliary electrical heating mouth according to detecting too low might the freezing of water temperature, promptly adopts the heat-preserving anti-freezing method; It two is through row's control valve is installed at corresponding site, and when low water temperature, the water of find time header and corresponding pipeline promptly adopts anhydrous freeze proofing.Then can only adopt anhydrous freeze proofing for flat plate collector.
Magnetic valve wherein, generally can install two is entering water electromagnetic valve and displacement magnetic valve; System also can unite two into one entering water electromagnetic valve and displacement magnetic valve; Comprehensively becoming a magnetic valve with dual-use function, that a magnetic valve only is installed is just passable; Both differences are that the control mode of controller has difference, simultaneously also need whether pressure-bearing decides according to heat collector.
Sensor wherein, a level sensor and two temperature sensors, level sensor is placed in the memory-type attemperater, mainly is the water level that detects in the water tank, also can adopt the altitude valve of machinery to replace; Two temperature sensors, one is placed in the heat collector hot water exit, and one is placed in the water tank.Controller can constantly receive the data from level sensor and temperature sensor, judges that the water level in the water tank is full, and controller then sends closes the entering water electromagnetic valve instruction, thereby stops the action of cold water displacement hot water; Hot water needs only a use in the water tank, and then controller receives the new data of level sensor, and controller control entering water electromagnetic valve door is opened, and can proceed the action of cold water displacement hot water; But whether really replacing the action power to make decision also needs controller to read the water temperature data on the temperature sensor in the heat collector; Water temperature in the heat collector arrives predetermined value; Controller starts the displacement magnetic valve, waits until that always water temperature reaches predetermined value otherwise still close the displacement magnetic valve.
Controller wherein, this controller are the control centres of whole solar water heater, and this controller can receive the data of multiple sensor, also can control a plurality of magnetic valves, and the button of Presentation Function and operation is arranged, and can control the switch of several big electric currents.
Because the memory-type attemperater in the utility model is the water tank of non-pressure-bearing; And the utility model therefore for the water outlet that makes hot water has pressure, need be installed a water outlet pressurization control valve at the delivery port of water tank for the not restriction of height of the installation site of water tank; This valve adopts frame for movement; Utilize the pressure of running water itself to drive the hot water in the water tank, make that discharge pressure is equal to the pressure of running water in the water tank, owing to sneak into the water temperature that running water can reduce water outlet; But because the hot water in the water tank is constant temperature hot water, the cold water of sneaking into just makes the water outlet water temperature reach the water temperature of having a bath.Also can an automatically controlled force (forcing) pump be installed at the delivery port of water tank accomplishes.
The order that solar water heater water route of the utility model and pipeline are connected when adopting level sensor is, running water is connected to entering water electromagnetic valve through water pipe, and the other end of entering water electromagnetic valve is connected to the cold water inlet of heat collector through water pipe; The hot water outlet of heat collector is installed a displacement magnetic valve; The other end of displacement magnetic valve is connected to the water inlet of memory-type attemperater through water pipe, or the hot water outlet of heat collector is not installed any magnetic valve is connected to the memory-type attemperater through water pipe water inlet.
Solar water heater water route of the utility model and pipeline are connected and adopt the order of altitude valve to be; Running water connects altitude valve through water pipe; Altitude valve connects entering water electromagnetic valve through water pipe; The other end of entering water electromagnetic valve is connected to the cold water inlet of heat collector through water pipe, and the hot water outlet of heat collector is directly linked the water inlet of memory-type attemperater through water pipe; Or running water connects altitude valve through water pipe; Altitude valve is directly connected to the cold water inlet of heat collector through water pipe; The hot water outlet of heat collector connects a displacement magnetic valve, and the other end of displacement magnetic valve is connected to the water inlet of memory-type attemperater through water pipe.The delivery port of water tank is installed a water outlet pressurization control valve or automatically controlled pressure pump, and the other end connects the hot water pipeline hot-water supply.According to the length of pipeline and the position of installation, section of tubing need install heat-insulation layer additional.Generally all insulation need be installed at the piping outside the house.
The memory-type attemperater and the heat collector of indication in the utility model, the relative position that both install is very convenient flexibly, and the relative position that heat collector is installed can be lower than the position of memory-type attemperater, also can be higher than the position of memory-type attemperater.Suggestion from the heat insulation effect of memory-type attemperater; Attemperater is placed in indoor; Another main Consideration is should flow into the memory-type attemperater as much as possible fast from the hot water that heat collector is replaced to be incubated, and can not be trapped in dissipated heat in the pipeline.
Heat collector in the utility model; Can join a memory-type attemperater by a heat collector; Also can join a memory-type attemperater by a plurality of heat collectors, can be between a plurality of heat collectors through connected in series, connection also can walk abreast; No matter be connected in series or parallel the connection between a plurality of heat collectors, it is connected in series connecting being connected in the utility model between later heat collector and the memory-type attemperater.
Heat collector and memory-type attemperater are two separate components separately in the utility model; Both are connected through external water pipe; Connected in series; Have only one to be connected pipeline between heat collector and the memory-type attemperater in logic, the water that gets into the memory-type attemperater through heat collector all is the hot water that in heat collector, is heated to predetermined temperature, and no external force intervention cold water or the water that in heat collector, is not added to predetermined temperature are can not enter into the memory-type attemperater.The solar water heater that this kind connects framework can also can very conveniently be applied in engineering solar water heater market so that be used in family.Though the separated type solar water heater is also arranged in the market; But be parallel-connection structure between heat collector and the water tank; Have two tube connectors to link to each other with inner water tank, and be the water in the heating water tank progressively, the water in solar thermal collector is started working in the water tank can't constant temperature.

The specific embodiment
Explain that at first the heat collector shown in this accompanying drawing all adopts vacuum tube to add the pattern of header, the flat-plate collector connected mode connected mode of accompanying drawing therewith is identical.The explanation of drawing no longer one by one thus.
Among Fig. 1; The relative heat collector in installation site (202) height of memory-type attemperater (201); This relative mounting positions has a large amount of uses at present in split balcony formula solar water heater; Flow to by water and describe the connection between the each several part, and understand the course of work that how to realize cold water displacement hot water.At first; Running water pipe is connected to running water water inlet (314); Running water inlet (314) is connected to an end of an entering water electromagnetic valve (203) through water pipe; Level sensor (305) in the complete controlled device of the switch of this entering water electromagnetic valve (203) (206) control, memory-type attemperater (201) detect water completely then controller (206) start-up control close entering water electromagnetic valve (203), otherwise then open entering water electromagnetic valve (203); The other end of entering water electromagnetic valve (203) connects the heat collector water inlet (310) of heat collector (202) through water pipe; Running water just flows in the header (315) of heat collector (202), and arrives heat collector delivery port (311), and controller this moment (206) can be through reading the data of heat collector cooling-water temperature sensor (316); These data are exactly the temperature of the water of current heat collector (202) the inside; If water temperature reaches the temperature that presets, controller (206) control displacement magnetic valve (204) valve is just fetched boiling water and just can be flow through displacement magnetic valve (204), otherwise the valve closing current are by obstructed.In view of the above, the running water that flowed into just now in heat collector (202) header (315) rests in the heat collector (202).
The vacuum heat collection pipe (313) of heat collector (202) is under shining of the sun shone; Constantly heat the running water of heat collector (202) header (315) inner bag, because the water of heat collector header (315) inner bag and few generally has only several liters; Therefore in a short period of time; The temperature of the water of heat collector header (315) inner bag just reaches predetermined temperature at once, after controller (206) collects these data, and the unlatching of controller (206) control displacement magnetic valve (204) valve; Displacement magnetic valve (204) valve open; Running water flows again, and the water in force heat collector (202) header (315) of the running water of newly coming in itself flows to heat collector delivery port (311), through displacement magnetic valve (204); The other end of displacement magnetic valve (204) is connected with water tank water inlet (301) through water pipe, and hot water just flow in the memory-type attemperater (201) and preserves.Why be that flow of hot water is gone into water tank at this moment, and cold water can not flow into water tank, key is that the running water promotion water of newly coming in flows to heat collector delivery port (311); But after the hot water of front all flows out heat collector; The temperature of the running water of newly coming in is low, and in this process, controller (206) is constantly gathered the data of heat collector cooling-water temperature sensor (316); When flowing to heat collector cooling-water temperature sensor (316); Because the low valve closing that makes that controller (206) control displacement magnetic valve (204) is interior of water temperature, running water is no longer mobile, and hot water gets in the memory-type attemperater (201) and is incubated storage; The cold water of newly coming in then rests in the heat collector (202), waits for the heating of heat collector (202).A process of front is exactly the complete procedure that the cold water of newly coming in is replaced the hot water in the heat collector; This process so moves in circles; This replacement process continues until in the memory-type attemperater (201) fills hot water; Controller (206) collects the information of level sensor (305) full water, and controller (206) cuts out entering water electromagnetic valve (203) running water and no longer flows into, and stops this displacement action.
Stop after this displacement action; Heat collector (202) is in two states, and is a kind of because heat collector (202) absorbs heat, and makes the water temperature in the header (315) be higher than displacement magnetic valve (204) unlatching temperature always; Then replace magnetic valve (204) valve open; Water in heat collector this moment (202) and the water UNICOM in the memory-type attemperater (201), beginning Natural Circulation heat transfer process makes that the water in the memory-type attemperater (201) is kept constant temperature.Another kind of state; The water temperature of heat collector (202) is lower than the unlatching temperature of displacement magnetic valve (204) all the time; Displacement magnetic valve (204) cuts out; Better keep the water temperature in the water tank, above certainly action all is to judge after controller (206) is constantly gathered heat collector cooling-water temperature sensor (316), and control displacement magnetic valve (204) is accomplished automatically then.
Through above replacement process, the temperature of the water of memory-type attemperater (201) is a definite temperature.The method of this displacement heat exchange, the speed of the water temperature that generation needs adopt the method for displacement heat exchange simultaneously considerably beyond the speed of the Natural Circulation heat exchange of using in a large number at present; The water temperature that produces is complete confirmable temperature; So no matter summer or winter, as long as no matter sunshine-duration length can produce hot water, the temperature of hot water is that what to confirm is controlled; Difference is that the short hot water amount who produces of sunshine-duration is few, and the sunshine-duration, the long hot water amount who produces was just many.Therefore the hot water in the water tank is full availability.
The use of hot water in the memory-type attemperater (201); Because the memory-type attemperater (201) of the utility model indication is non-press-bearing water tank; The hot water itself that water outlet of water tank (302) is located does not out have big pressure; In order to increase the discharge pressure of hot water, locate to connect a water outlet pressurizing valve (205) at water outlet of water tank (302), this valve relies on the pressure of running water itself to drive the hot water in the water tank; Make and locate to produce the mixed hot water of similar tap water pressure at pressurization delivery port (306); Because this valve has a rational hot and cold water proportioning, adds that the water temperature in the memory-type attemperater (201) is a definite value, the pressurization mixing water that therefore comes out has a suitable water temperature to use.If must come out high-temperature water certainly, then locate to install an automatically controlled force (forcing) pump (208) and get final product at water outlet of water tank (302).
Among Fig. 2; The installation site of memory-type attemperater (201) will be hanged down with respect to heat collector (202); This kind installation method is applied on roof, the engineering many at the separated type solar water heater at present; Be installed in the roof to heat collector (202) exactly, and memory-type attemperater (201) is placed on indoor.This method of attachment and operation principle and front are described close; In order to describe the course of work and the operation principle that the utility model adopts single magnetic valve; Displacement magnetic valve of no use (204) in this diagram that is to say that whole system only uses entering water electromagnetic valve (203).The course of work and the working mechanism that this framework adopts an entering water electromagnetic valve (203) below described.
At first to make the whole system operational excellence; Two kinds of operating mechanisms are arranged; Parametric method between fixing in the time of first kind: when bringing into use in this system; Need test entering water electromagnetic valve (203) to open the time of valve and the relation of flow of inlet water; Say to know exactly entering water electromagnetic valve (203) opens how long inflow is just filled water to heat collector (202) inner bag, and this time parameter can set according to the heat collector different specifications in advance generally speaking exactly in controller (206), need only in the erecting bed and select the heat collector (202) of corresponding specification just can directly call this parameter.
Controller (206) has had entering water electromagnetic valve (203) opening time parameter; System brings into operation, and controller (206) is gathered the data of level sensor (305) earlier, and the water level in the water tank is discontented; Call the time parameter of entering water electromagnetic valve (203); Open entering water electromagnetic valve (203) according to time parameter, running water flow in heat collector (202) inner bag, and the running water of coming in is just filled heat collector; Entering water electromagnetic valve (203) is opened the time to closing entering water electromagnetic valve (203), stops into water.Running water is in heat collector (202); Constantly heat ground water in the heat collector through the heat collecting vacuum pipe (313) in the heat collector (202); This process middle controller (206) is constantly gathered the water temperature data of heat collector cooling-water temperature sensor (316), in case the water temperature data that collect reach predetermined temperature, controller (206) calls the time parameter of entering water electromagnetic valve (203) once more; Open entering water electromagnetic valve (203) according to time parameter; Running water flows through entering water electromagnetic valve (203) once more and gets in the heat collector (202), and the running water of newly coming in, the energy of dependence running water itself flow into original hot water in heat collector in the memory-type attemperater (201) through water pipe and store; When the running water of newly coming in just all pushes water tank to hot water all in the heat collector; The time parameter of opening of entering water electromagnetic valve (203) arrives, and controller (206) cuts out entering water electromagnetic valve (203), and running water stops to flow.More than be exactly that system adopts in single electromagnetic valve controlling system, the process of a complete cold water displacement hot water, this process is so reciprocal, up to controller (206) collects the full data of water through level sensor (305) till, stops replacement process.
Second kind; Instant collection in worksite control method; Principle is exactly that entering water electromagnetic valve (203) is opened and carried out the replacement process kind; Controller (206) is constantly gathered the data of the cooling-water temperature sensor (316) in the heat collector (202), is lower than setting value in case collect water temperature, and then controller (206) control entering water electromagnetic valve (203) is closed and stopped displacement work.The detailed process details is no longer described.It should be noted that in addition owing to long through water pipe, hot water is trapped in the water pipe for a long time to the general distance of the water tank water inlet (301) of memory-type attemperater (201) from heat collector delivery port (311).
The method of work and the process that adopt two magnetic valves and a magnetic valve in the system have below been described respectively; In fact the described framework of the utility model; No matter be that Fig. 1 illustrates or Fig. 2 signal, can adopt a magnetic valve or two magnetic valves simultaneously, adopt the course of work of two magnetic valves identical with Fig. 1; Adopt the course of work of a magnetic valve identical with Fig. 2; Uniquely different be, when adopting a magnetic valve, the heat collector that is connected (202) can be pressure-bearing also can be non-pressure-bearing; And when adopting the work of two magnetic valves, the general requirement of the heat collector that is connected (202) is pressure-bearing.
In diagram, no matter be in memory-type attemperater (201) or the heat collector (202), an electric satellite interface is all arranged, the auxiliary electrical heating gate (304) of memory-type attemperater (201).The major function of this auxiliary electrical heating gate (304) has two, and when sunlight was not enough, the hot water that needs surpassed the hot water in the water tank, and then can adopting meets an urgent need adds cold water to water tank, starts electric heating function; Another, the hot water of trunkful in the water tank is not owing to there is the sun for a long time, and water temperature descends, and then can adopt electric heating function that water in the water tank is heated.The header electrical heating auxiliary ports (312) of heat collector (202); The major function of this auxiliary ports is: the demand of hot water surpasses the volume of water tank, needs continuously hot-water supply, then can open this function; Accelerate to heat speed, more hot water amount is provided with this; The optional function of another one is that the water temperature in the heat collector is low excessively, for preventing the generation of freezing phenomenon, starts this function.
