Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
With reference to figure 3, as shown in Figure 3, a kind of user side distribution of the present invention stores hot water supply system, comprise the circulating water supply system formed with total water tank 20 of thermal source 10, the water supply line 40 being provided with heat-exchanger pump 30, user side water equipment 50 and circulation pipe 60, user side water equipment 50 is equipped with back pressure transfiguration boiler 70, and back pressure transfiguration boiler 70 is communicated with water supply line 40 by water supply arm 41; Circulation pipe 60 is communicated with filling pipe 90, filling pipe 90 is provided with check-valves 80; The back pressure transfiguration boiler 70 of each user side water equipment 50 is equipped with moisturizing limit switch 75, and each moisturizing limit switch 75 is connected by moisturizing limit signal line 100 and is connected to heat-exchanger pump 30;
Connected by the moisturizing limit switch 75 of the back pressure transfiguration boiler 70 on loop, then the moisturizing limit switch 75 (see figure tetra-) of any one user side back pressure transfiguration boiler 70 sends signal and all runs starting heat-exchanger pump 30 the moisturizing process entering user side back pressure transfiguration boiler 70.Can pressure reduction be produced between feed pipe 40 and circulation pipe 60 this moment, under the effect of pressure of supply water, first circulation pipe 60 and total water tank 20 be pushed back to the cold water stored in water supply network (comprising feed pipe 40 and water supply arm 41).After the cold water of water supply network is emptying, be full of hot water in pipe network, the temperature control three-way valve of back pressure transfiguration boiler 70 is switched to water compensating state, and hot water is full of to hot water the moisturizing of each user side back pressure transfiguration boiler 70 by pipe network.After water-filling terminates, in water supply network, hot water flow is reduced to zero, and the pressure of feed pipe 40 sends termination of pumping signal by raising further, controls heat-exchanger pump 30 automatically out of service.
When user side water equipment 50 uses hot water, in the hot-water cavity 71 of back pressure transfiguration boiler 70, hot water flows out, and under back pressure effect, hot-water cavity 71 volume of back pressure transfiguration boiler 70 gradually reduces.When the hot-water cavity 71 of any one back pressure transfiguration boiler 70 reduces to set volume, moisturizing limit switch 75 sends moisturizing signal and enters above-mentioned moisturizing process till all user sides water tank 70 is full of.
With reference to figure 4, back pressure transfiguration boiler 70 comprises a thermal-insulating body, there is adiabatic partition 73 that casing is divided into hot-water cavity 71 and back pressure cavity 72 in casing, the top of hot-water cavity 71 is provided with moisturizing limit switch 75, hot-water cavity 71 side is provided with the hot water outlet pipe 78 be communicated with user side water equipment 50, opposite side is provided with water inlet pipe 77, and water inlet pipe 77 is communicated with water supply arm 41 by temperature control three-way valve 79; Back pressure cavity 72 is communicated with circulation pipe 60 by pressure-equalizing pipe 710, and pressure-equalizing pipe 710 is connected to temperature control three-way valve 79 by bypass line 711; Upper limit centring ring 74 is also provided with in hot-water cavity 71.
After moisturizing limit switch 75 sends signal, hot water used in system pump 30 starts, feed pipe 40 pressure raises, at this moment because water temperature is low, the port conducting that temperature control three-way valve 79 is connected with water supply arm 41 and bypass pipe 711, the cold water in water supply network flows into circulation pipe 60 by bypass pipe 711 and pressure-equalizing pipe 710.After cold water is emptying, water temperature raises, and temperature control three-way valve 79 action makes bypass close, water supply arm 41 and water inlet pipe 77 conducting, and hot water flows into hot-water cavity 71 to being full of.In water filling process, exhausted heat insulation disconnected 73 under the promotion of upper and lower two ends pressure reduction, and be moved downward to bottom gradually, moisturizing terminates.After moisturizing terminates, in feed pipe 40, hot water flow drops to zero, and heat-exchanger pump 30 is in idling conditions, and motor current declines, and produces termination of pumping signal, and heat supply water pump stops.
With reference to figure 5, hot water effluent, 78 are connected with a temperature control heating pipe 76, temperature control heating 76 pipe comprises a lagging casing 761, the side of lagging casing 761 is provided with delivery port 765 and is communicated with hot water outlet pipe 78, the opposite side of lagging casing 761 is provided with water inlet 764, is provided with temperature control heating element 762 and temperature element 763 in lagging casing.
When hot water water temperature is normal, tubulose temperature control heating element 762 is in off-position.When the long period do not use hot water in case to cause in case, hot water temperature is lower than lowest set temperature time, the current flowing through tubulose temperature control heating element 762 from water inlet 764 can cool temperature element 763 makes tubulose temperature control heating element 762 circuit turn-on, and current are heated; If without the need to using hot water constantly, in pipe, water does not flow, and the hot water at temperature element 763 place can be warming up to the design temperature upper limit very soon, sends power-off signal.Tubulose temperature control heating element 762 only water temperature too low and when having current to flow in temperature control heating pipe 76 work.
Present invention achieves a kind of novel energy-saving and water-saving hot water supply system.Compared with prior art the present invention is by storing the distribution of part hot water nearby at wetting system 50 place, user side, greatly reduces the hot water circuit time of circulation pipe network, reduces heat consumption and the water pump power consumption of circulation pipe network in hot water transmission & distribution process.The energy consumption qualitative analysis of the present invention and technical scheme one is as follows: to technical scheme one, because hot water must not stop circulation during use in circulation pipe network, pipe network is in radiating state all the time, its heat-exchanger pump 30 power consumption and pipe network heat dissipation stream all can be considered constant, pipe network heat dissipation stream curve A in Fig. 6 represents, heat-exchanger pump power consumption curve C in Fig. 7 represents; The present invention only water supply network water temperature in moisturizing phase pipe is in normally, moisturizing terminates hot water in Posterior circle pipe network and no longer flows, water temperature drops to environment temperature gradually, another because of the lossless heat of circulation pipe 60, thus its pipe network heat dissipation stream is roughly the half of technical scheme one during moisturizing, reduces to zero gradually during non-moisturizing with the water temperature drop in feed pipe.Therefore, pipe network heat dissipation stream curve B in Fig. 6 represents, water circulating pump power consumption pulse curve D in Fig. 7 represents.Thus can find out compared with technical scheme one, the present invention reduces pipe network energy consumption and water pump power consumption aspect has significant advantage.
The explanation of above example just understands core concept of the present invention for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
