Two, heat exchange circulation, hot water use pattern

1, the automatic temperature difference heat exchange, circulation, the emptying pattern: the vacuum heat collection pipe 25 on heat collector 12 absorbs solar energy, water in the metal heat exchanger tube 33 wherein boiled in a covered pot over a slow fire shine heating, the water at low temperature that produces in hot water and the heat collector water tank 20 is carried out the cold and hot exchange of gravity type, its temperature is risen, when rise to indoor water tank 1 in water temperature temperature difference when setting value, intelligent controller 28 is accepted each assembly action of signal command system that heat collector water tank temperature sensor 24 and water tank temperature sensor 27 send, automatically start temperature difference cycle heat exchange program (as hand-operated forced circulation time: press intelligent controller 28 cocycle keys): as Fig. 2, shown in Figure 3, circulation line control valve 7 is opened, water circulating pump 8 startings, the last water control valve of closing on the watering pipeline 34 cuts off watering pipelines 3, and band setting-out in the watering pipeline 3 or band press the running water can't the inlet chamber inner water tank; Indoor water tank 1 is air-breathing by the sealing breather valve 2 of upper end, the circulation watering pipeline 6 that water in the indoor water tank 1 was drained after the circulation by last time enters in the heat collector water tank 20, high-temperature water in the heat collector water tank 20 is ejected, the circulation drainage pipeline 13 that had been drained after the circulation through last time flows in the indoor water tank 1 through the drainage pipeline connector 45 of check-valves 14 by indoor water tank 1; As Fig. 4, shown in Figure 5, ponding pipe-line control valve 18 cuts out, cut off ponding discharge pipe 17, circulation line control valve 7 is opened, water circulating pump 8 startings, the last water control valve of closing on the watering pipeline 34 cuts off watering pipelines 3, and band setting-out in the watering pipeline 3 or band press the running water can't the inlet chamber inner water tank; Following water ponding discharge pipe 41 highway sections in non-return valve 42 left sides on the following water ponding discharge pipe 41 are cut off 6 connections to circulation drainage pipeline 13 directions of circulation watering pipeline by non-return valve 42 unidirectional checks; Indoor water tank 1 is air-breathing by the sealing breather valve 2 of upper end, can not enter ponding discharge pipe 17 during the circulation watering pipeline 6 of the water in the indoor water tank 1 by being drained after the circulation last time and can not enter circulation drainage pipeline 13 by water ponding discharge pipe 41 down; Can only enter in the heat collector water tank 20, high-temperature water in the heat collector water tank 20 is ejected the circulation drainage pipeline 13 that had been drained after the circulation through last time, flow in the indoor water tank 1 through the drainage pipeline connector 45 of check-valves 14 by indoor water tank 1, after this apparatus system cycle heat exchange and circulation line emptying, ponding pipe-line control valve 18 is opened, and opens ponding discharge pipe 17; As shown in Figure 6, circulation line control valve 7 is opened, water circulating pump 8 startings, and the last water control valve 4 of closing on the watering pipeline 3 cuts off watering pipelines 3, and band setting-out in the watering pipeline 3 or band pressure running water can't the inlet chamber inner water tanks; Indoor water tank 1 is air-breathing by the sealing breather valve 2 of upper end, the circulation watering pipeline 6 that water in the indoor water tank 1 was drained after the circulation by last time enters in the heat collector water tank 20, high-temperature water in the heat collector water tank 20 is ejected, and the circulation drainage pipeline 13 that had been drained after the circulation through last time flows in the indoor water tank 1 through the delivery port 35 of check-valves 14 by indoor water tank 1.

By above-mentioned cycle heat exchange, when the water in heat collector water tank 20 and the indoor water tank 1 drops to setting value through the temperature difference behind the cycle heat exchange, perhaps to default cycle heat exchange during the concluding time, intelligent controller 28 sends signal, each assembly auto-action of command system (or manually pressing intelligent controller 28 cocycle keys again), water circulating pump 8 stops.As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the water in the drainage pipeline 13 that circulates this moment relies on the nature drop through check-valves 14, flows in the indoor water tank 1 by the drainage pipeline connector on the indoor water tank 1 45; As shown in Figure 6, circulate this moment drainage pipeline 13 water rely on the nature drop through check-valves 14 by in the delivery port 35 flowed into chamber inner water tanks 1 of indoor water tank 1.

As Fig. 2, shown in Figure 6, water circulating pump 8 stops, circulation line control valve 7 time-delay closings (generally delaying time 0.3-2 minute), water in the circulation watering pipeline 6 relies on the nature drop through water circulating pump 8, circulation line control valve 7, in watering pipeline 3 inlet chamber inner water tanks 1, indoor water tank 1 is discharged the gas of inspiration in the cycle heat exchange process by the sealing breather valve 2 of upper end again; After the water emptying in the circulation watering pipeline 6, circulation line control valve 7 time-delay closings finish (generally delaying time 0.3-2 minute), close; As shown in Figure 3, water circulating pump 8 stops, circulation line control valve 7 closes; As Fig. 4, shown in Figure 5, the ponding pipe-line control valve 18 on the ponding discharge pipe 17 is opened and is delayed time, and still is in closed condition, cuts off ponding discharge pipe 17, and water circulating pump 8 stops, circulation line control valve 7 is closed; As Fig. 3, Fig. 4, shown in Figure 5, the water dependence nature drop in the circulation watering pipeline 6 can only be through emptying pipeline 15, emptying pipeline check-valves 16, watering pipeline 3, in indoor water tank water inlet 34 flowed into chamber inner water tanks 1; Indoor water tank 1 is discharged the gas of inspiration in the cycle heat exchange process by the sealing breather valve 2 of upper end again; After the water emptying in the circulation watering pipeline 6, Fig. 4, shown in Figure 5, ponding pipe-line control valve 18 delayed start-ups are moved to end (generally delaying time 0.3-2 minute), open ponding discharge pipe 17.

After systemic circulation heat exchange and heat exchanging pipe emptying, the water in heat collector water tank 20 and the indoor water tank 1 still keeps the state of filling with before the heat exchange circulation; Indoor water tank 1 is in atmospheric pressure state in this cycle heat exchange and heat exchanging pipe evacuation procedure; System finishes this device heat exchange circulation and heat exchange circulation back circulation line evacuation procedure successively repeatedly automatically by above-mentioned situation action, and water in the indoor water tank 1 is heated up, and finishes solar energy hot water process.

2, the discharge method of hot water use and swelling water: after this device cycle heat exchange and circulation line emptying, though the water in heat collector water tank 20 and the indoor water tank 1 still keeps the state of filling with before the heat exchange circulation, but the indoor water tank 1 of artesian condition before the cycle heat exchange is switched to the indoor water tank 1 of heat exchange circulation back atmospheric pressure state, a small amount of swelling water (A represents swelling water storage area in the utility model system among Fig. 1-Fig. 6) that in this process, can produce, as not discharging at once, this device is after repeatedly cycle heat exchange and circulation line emptying, can in circulation line, accumulate, make the water in the circulation line of indoor water tank 1 upper end can not realize thorough emptying.

As Fig. 2, shown in Figure 6, select check-valves 14 on the circulation drainage pipeline 13 for use less than the overcurrent latus rectum of circulation watering pipeline 6; Perhaps, on the circulation drainage pipeline, flow control valve is installed, during water emptying in circulation watering pipeline 6, the circulation drainage pipeline 13, before circulation line control valve 7 time-delay closings, (generally delayed time 0.52 minute), allow the water in the circulation watering pipeline 6 enter indoor water tank 1 earlier than the water in the circulation drainage pipeline 13, cause indoor water tank 1 because the swelling water that artesian condition produces with the switching of atmospheric pressure state only a quilt existed in the circulation drainage pipeline 13; As Fig. 3, Fig. 4, shown in Figure 5, cycle heat exchange finishes, water circulating pump 8 stops, circulation line control valve 7 is closed, the water in the drainage pipeline 13 of circulating this moment rely on the nature drop through check-valves 14 by in the drainage pipeline connector 45 flowed into chamber inner water tanks 1 of indoor water tank, water in the circulation watering pipeline 6 relies on the nature drop through emptying pipeline 15, emptying pipeline check-valves 16, watering pipeline 3, in indoor water tank water inlet 34 flowed into chamber inner water tanks 1; The swelling water that causes indoor water tank 1 to produce because of the switching of artesian condition and atmospheric pressure state is existed in circulation drainage pipeline 13 and the circulation watering pipeline 6; After the water emptying in Fig. 4, the circulation watering pipeline 6 shown in Figure 5, ponding pipe-line control valve 18 is opened time-delay and is finished (generally delaying time 0.3-2 minute), opens ponding discharge pipe 17.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, open mixed water valve 31 when hot water uses and go to the hot water end, if circulation drainage pipeline 13, there is swelling water in the circulation watering pipeline 6, water level is higher than delivery port 35 positions on indoor water tank 1 inner bag top so, open and mix water valve 31, the hot water of delivery port 35 upper ends of indoor water tank 1 and the water among the hot water outlet pipe 32 rely on nature drop gravity to flow out and mix water valve 31, make in the indoor water tank 1 of filling with water originally certain space has been arranged, this moment, sensor 10 (generally can be water flow sensing unit) or gauge tap 9 (generally can be near the switching regulator sensor) were though action, but 4 opening times of water control valve delayed time (delay time generally can be 1-3 second) are gone up in command system instruction, the expansion water yield that is higher than delivery port 35 positions on indoor water tank top in the circulation line flows in the indoor water tank 1 through the drainage pipeline connector 45 of indoor water tank 1 earlier, and perhaps the expansion water yield that has in (as shown in Figure 6) circulation drainage pipeline 13 directly flows out by hot water effluent's pipeline 32 and mixes water valve 31; As Fig. 2--shown in Figure 6, when the water level in the circulation line is reduced to about delivery port 35 positions of indoor water tank approximately, after promptly mixed water valve 31 is emitted the water yield of swelling water, last water control valve 4 delayed start-ups finish (delay time generally can be 13 seconds), open watering pipeline 3, band setting-out in the watering pipeline 3 or band are pressed running water jacking indoor water tank 1, through the delivery port 35 of indoor water tank 1 hot water are ejected by hot water effluent's pipeline 32 and mix water valve 31; As shown in Figure 5, open mixed water valve 31 when hot water uses and go to the hot water end, last water control valve 4 delayed start-ups finish (delay time generally can be 1-3 second), open watering pipeline 3, band setting-out in the watering pipeline 3 or band are pressed running water jacking indoor water tank 1, delivery port 35 through indoor water tank 1 ejects mixed water valve 31 with hot water by hot water effluent's pipeline 32, owing on hot water effluent's pipeline 32 and the outlet pipeline 49 that circulation watering pipeline 6 is connected pipeline check-valves 48 is housed, pipeline check-valves 48 cuts off the highway section check of the outlet pipeline 49 of circulation watering pipeline 6 directions, so the band setting-out that this moment, indoor water tank 1 ejected can not enter in the circulation watering pipeline 6.

Stop using hot water: close and mix water valve 31, sensor 10 (generally can be water flow sensing unit) or gauge tap 9 (generally can be) action near the switching regulator sensor, intelligent controller acknowledge(ment) signal commander goes up water control valve 4 and closes, and cuts off watering pipeline 3, finishes the hot water process of using; Indoor water tank 1 is in artesian condition in this process; Because in this process, the swelling water in circulation line is able to preferential discharging, avoided to realize because of the phenomenon that swelling water is accumulated in the circulation line generation of the normal emptying problem of circulation line;

At this device cycle heat exchange, hot water during the circulation line emptying uses: as Fig. 2, Fig. 3, shown in Figure 4, during the native system cycle heat exchange, water circulating pump 8 start with the water in the indoor water tank 1 extract out through last time cycle heat exchange the circulation watering pipeline of emptying enter heat collector water tank 20, high-temperature water in the heat collector water tank 20 is ejected through the drainage pipeline connector 45 inlet chamber inner water tanks 1 of circulation drainage pipeline by indoor water tank 1, indoor water tank 1 water level is lower than the delivery port 35 of indoor water tank in this process, use hot water to open when mixing water valve 31, mix 31 water that flow out in hot water effluent's pipeline 32 of water valve, though the sensor 10 on hot water effluent's pipeline 32 moves but goes up water control valve 4 in the systemic circulation heat exchange, can't open by system's control, can not open watering pipeline 3, the band setting-out can not the inlet chamber inner water tank 1 ejects hot water, so hot water can not use in this process; As shown in Figure 6, during the native system cycle heat exchange, water circulating pump 8 starts, with the water in the indoor water tank 1 extract out through last time cycle heat exchange the circulation watering pipeline 6 of emptying enter heat collector water tank 20, high-temperature water in the heat collector water tank 20 is ejected, pass through hot water effluent's pipeline 32 through circulation drainage pipeline 13, the delivery port 35 inlet chamber inner water tanks 1 of indoor water tank, use hot water this moment, open and mix water valve 31, high-temperature water in the heat collector water tank 20 directly flows out by hot water effluent's pipeline 32 through circulation drainage pipeline 13 and mixes water valve 31, though the sensor 10 on hot water effluent's pipeline 32 moves but goes up water control valve 4 in the systemic circulation heat exchange, can't open by system's control, can not open watering pipeline 3, the band setting-out can not inlet chamber inner water tank 1, the systemic circulation heat exchange, after emptying finishes, last water control valve 4 is accepted the system command delayed start-up, open watering pipeline 3, band setting-out inlet chamber inner water tank 1 is filled with water with indoor water tank 1, last water control valve 4 delayed start-ups finish to close, cut off watering pipeline 3, though the continuous use of hot water is arranged in this process, exists high-temperature water in the heat collector water tank 20 directly to flow out through hot water effluent's pipeline 32 and mix water valve 31 and scald people's problem and take place by circulation drainage pipeline 13; As shown in Figure 5, during the native system cycle heat exchange, water circulating pump 8 starts extracts the water in the indoor water tank 1 out, through last time cycle heat exchange the circulation watering pipeline 6 of emptying enter heat collector water tank 20, high-temperature water in the heat collector water tank 20 is ejected, through the drainage pipeline connector 45 inlet chamber inner water tanks 1 of circulation drainage pipeline 13 by indoor water tank 1, use hot water in this process, open mixed water valve, the water circulating pump 8 that starts, because there is hot water line's check-valves 47 outlet pipeline 49 and hot water effluent's pipeline 32 junctions that are connected with circulation watering pipeline 6 on hot water effluent's pipeline 32 of indoor water tank direction, hot water line's check-valves 47 cuts off the line segments check of hot water effluent's pipeline 32 to indoor water tank 1 direction, so be recycled the outlet pipeline 49 that hot water in the indoor water tank 1 that water pump 8 extracts out can only be through being connected with circulation watering pipeline 6, hot water effluent's pipeline 32 flows out and mixes water valve 31, because the mixed water valve 31 of outflow is still the hot water in the indoor water tank 1, when using hot water, in the continuous use that guarantees hot water, when having avoided cycle heat exchange, high-temperature water directly flows out through hot water effluent's pipeline 32 by circulation drainage pipeline 13 and mixes the generation that water valve is scalded people's problem in the heat collector water tank 20.

As Fig. 2, Fig. 3, shown in Figure 6, circulation line control valve 7 has interlock function with last water control valve 4, and promptly when this device cycle heat exchange, circulation line emptying ON cycle pipe-line control valve 7, last water control valve 4 can not be unlocked; And when water control valve 4 was opened on using hot water, circulation line control valve 7 can not be unlocked.

In Fig. 4, Fig. 5, having only ponding pipe-line control valve 18 to be in closed condition circulation line control valve 7 just can be unlocked, water circulating pump 8 could be started, and ponding pipe-line control valve 18 has interlock function with last water control valve 4, promptly in this device cycle heat exchange, circulation line emptying, when closing ponding pipe-line control valve 18, last water control valve 4 can not be unlocked; And using hot water, when last water control valve 4 was opened, ponding pipe-line control valve 18 can not be closed.

In Fig. 4, Fig. 5, safety, warning function: when the check-valves 14 on the circulation drainage pipeline 13 damages, when using hot water, band setting-out in the watering pipeline 3 or band are pressed running water jacking indoor water tank 1, delivery port 35 through indoor water tank passes through hot water effluent's pipeline 32 with hot water, and a part of water flows out through mixing water valve 31; The check-valves 14 that part water damages on drainage pipeline connector 45, circulation drainage pipeline 13 and the circulation drainage pipeline of indoor water tank, following water ponding discharge pipe 41, non-return valve 42, ponding discharge pipe 17 are disposed to floor drain 46; And when on the pipeline between watering pipeline 3 and the circulation watering pipeline 6 or the control valve on hot water effluent's pipeline 32 and the outlet pipeline 49 that circulation watering pipeline 6 is connected, during as circulation line control valve 7 or emptying pipeline check-valves 16 or 48 damages of pipeline check-valves, on using hot water or indoor water tank 1 during water, band setting-out in the watering pipeline 3 or band are pressed in the running water part jacking indoor water tank 1, and a part of water can emit to floor drain 46 by ponding discharge pipe 17 through circulation watering pipeline 6 through damaging control valve; The band setting-out of jacking indoor water tank 1 emits to floor drain 46 by ponding discharge pipe 17 through circulation watering pipeline 6 through hot water effluent's pipeline 32 of the delivery port 35 of indoor water tank 1 and lower end, outlet pipeline 49, the pipeline check-valves 48 that damages; When last water control valve 4 damages, band setting-out or band pressed running water also to enter circulation watering pipeline 6 and circulation drainage pipeline 13 by watering pipeline 3 inlet chamber inner water tanks 1 before systemic circulation heat exchange, purge routine finished, after systemic circulation heat exchange, purge routine finished, this part water can emit to floor drain 46 by ponding discharge pipe 17; When ponding pipe-line control valve 18 damaged, during the systemic circulation heat exchange, cycle heat exchange water can emit by ponding discharge pipe 17 through circulation watering pipeline 6; Therefore, the design of following water ponding discharge pipe 41 and ponding discharge pipe 17 has avoided being full of water in circulation drainage pipeline 13 that the damage because of the various control valve members of system causes, the circulation watering pipeline 6 can not realize normal emptying, causes the winter circulation line to freeze the generation of stifled problem; And, if the high temperature swelling water of solar thermal collector 12 generation high temperature expanding gas and trace discharges smoothly by the circulation drainage pipeline 13 of emptying, following water ponding discharge pipe 41, circulation watering pipeline 6 and ponding discharge pipe 17 and discharges, changed the history that solar thermal collector 12 in the past can only be breathed by breather valve, avoided solar thermal collector in the winter time breather valve freeze the stifled generation that produces the bloated booster of vapour, splits accidents such as courage because of steam distillation.Fault alarm 19 (generally can be water flow sensing unit) is housed on this apparatus system ponding discharge pipe 17, when system certain control valve member damage produce undesired current by the time in time report to the police, the control valve member of damage is safeguarded as early as possible.

As Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, after this device uses certain hour, indoor water tank 1 bottom can be opened normally closed hand-operated valve 26 if any the impurity of precipitation, open mixed water valve 31 and go to the hot water end, sensor 10 (generally can be water flow sensing unit) or gauge tap 9 (generally can be) action near the switching regulator sensor, water control valve 4 delayed start-ups are gone up in the command system instruction, band setting-out in the watering pipeline 3 or band are pressed running water jacking indoor water tank 1, delivery port 35 and drainage pipeline connector 45 through indoor water tank eject mixed water valve 31 with hot water by hot water effluent's pipeline 32 together, and the impurity of the precipitation in the indoor water tank can flow out thereupon.Close normally closed hand-operated valve 26, mix water valve 31, finish the blowdown process of indoor water tank.
