Be example with Jinhua, Zhejiang city weather condition below, the energy-conservation situation of solar water heater and shower with long-acting recovery of residual heat of the present invention is used in contrast:
It is reported: " numeral that Jinhua information centre of meteorological observatory Wang Jianhua provides shows that nearly 30 years, annual fine number in city's was 206.5 days; Nearly 50 years, the annual sunshine-duration was 1954.2 hours.From sunshine condition, be fit to very much promote the use of solar energy." (information source: Jinhua daily paper
Http:// www.cheaa.com/News/Chanpin/ChuWei/2008/8/67231140201.htm l)
Doing one relatively with solar water heater under equal duration and the discharge condition: shower with long-acting recovery of residual heat of the present invention (5 ℃ of water inlet temperature) under the environmental condition of the harshest cold year moves 365 days, and 15 minutes/day, that is:
1/4 hour * 365 days=273.75KW/h of 3KW ÷
The power consumption of solar water heater:
365 days-206.5 days=158.5 days
1/4 hour * 158.5 days=475.5KW/h of 12KW ÷
Shower with long-acting recovery of residual heat year of the present invention is energy-conservation to be:
475.5KW/h-273.75KW/h＝201.75KW/h
That is to say that shower with long-acting recovery of residual heat of the present invention is than solar water heater year economize on electricity 201.75 degree
Through above-mentioned comparison, confirm that shower with long-acting recovery of residual heat of the present invention has than traditional energy-saving water heater (like solar heat exchanger) energy-saving advantages more.

Do further explain in the face of several key technologies of the present invention down:
One. the self-cleaning hair stripper:
The present invention is directed to the shower system specific (special) requirements; Well-designed self-cleaning hair stripper, this device filters wall 17, lamina tecti 18, hydraulic piston 19, back-moving spring 20, change-over panel 21, filter back water water storage flume 22, washer jet 23, formations such as fistulae 24 and drainpipe 25, sealing ring 26, jump ring 27, waste water filtering 28 down by " labyrinth " formula.
Its course of work is: after shower finishes, press stop key, and single-chip microcomputer delayed start-up solenoid purge valve 12, water pressure pushing hydraulic piston 19 is up; Drive filtration wall 1 and pack up downwards, the filtering thing is picked out, and washer jet 23 washes filtering thing 24 times rows of fistulae extremely down simultaneously; The filtering thing is discharged in change-over panel 21 conversion, and the time-delay cleaning valve that finishes is closed; Water pressure pushing liquid presses piston pole 19 resets with spring 20 pressure through washer jet 7 pressure releases, and process finishes.
Its characteristics are following:
Other solid matters that produce in chaeta that we produce when knowing people's bathing and the use very easily stop up devices such as heat exchanger, water pump, filtration system, and have designed the self-cleaning hair stripper among the present invention especially.The solid matters such as chaeta that produce in the filtering bathing in time of this stripper guarantee that waste heat waste water smoothness is not detained, treat bathing finish shut down after; Automatically control cleaning valve through single-chip microcomputer, utilize the pressure of running water, order about water pressure pushing hydraulic piston push rod and rise; Impel " labyrinth " formula to filter wall sinking prior art and generally adopt forms such as filter screen filter pulp, and the present invention is through narrow circuitous aquaporin, with labyrinth form guiding waste water stream; Be detained the filtering thing simultaneously, and do not allow waste water to be detained), open washer jet; The turnover plate type change-over panel that links is simultaneously accomplished the removing of foreign material such as hair automatically and is automatically reset.This stripper filtering chaeta is thorough, does not stop and is detained waste heat waste water, and cost of manufacture is low, and is convenient automatically, need not artificial the cleaning, can guarantee the operation that water heater is permanently effective, and its material corrosion can not take place with plastics and stainless steel spring making.
Two. spiral antiscale heat exchanger:
Spiral antiscale heat exchanger is very crucial parts among the present invention, adopts two long 8m, wide 8cm; The mirror face stainless steel material of thick 0.2-0.3mm; Parallel two row punchings become corrugated, and stainless steel strip edge and mid portion stamp out the bonding hole (as the cinefilm shape) of diameter 2-3mm, use the plastic strip bound edge of isometric thick 1mm, wide 10mm again; Mid portion is also dosed same plastic strip as brace rod simultaneously; Twine back supersonic welding hot pressing with spiral form and make the plastic strip welded seal, connect cold and hot side Inlet and outlet water joint again and form, this making can realize welding through ultrasonic technique.
Its characteristics are following:
1. heat exchange efficiency is high.The cold and hot matchmaker's wing passage of heat exchanger of the present invention cross section length and width ratio big (50mm/2mm), the big (0.8m of formed heat-transfer surface
2), heat-conducting approaches (0.2-0.3mm stainless steel), and logarithmic mean temperature difference (LMTD) is in 5 ℃.
As with 5 ℃ of the initial water temperatures of electrical heating, flow is 4.3L/min, 45 ℃ of output temperatures keep electrical power, be exactly to reclaim the back water temperature to have promoted 40 ℃.Specific heat of water appearance=4200J/kg ℃, the heating wire thermal efficiency is made as 100%
Calculate: P
160s * 4200J/kg ℃ * 40 ℃=12040W of=4.3kg ÷ (1W=1 Jiao/second)
Through calculating; We have known that 40 ℃ of needs 12040W of 4.3L/min heating keep the ability shower; And the present invention (its logarithmic mean temperature difference (LMTD) is in 5 ℃ after through spiral antiscale heat exchanger; Deduct 5 ℃ of shower losses so), the water temperature that advance heater this moment is 35 ℃, heater only need heat 10 ℃ can reach 45 ℃ of shower water temperatures
Calculate: P
260s * 4200J/kg ℃ * 10 ℃=3010W of=4.3kg ÷ (1W=1 Jiao/second)
P
1-P
2＝12040W-3010W＝9030W
Learn that through calculating spiral antiscale heat exchanger can recycle the waste heat of 9030W from waste water, and this system only need import the 3010W electrical power and can keep bathing, than general directly-heating type water heater (needing 12040W) economize on electricity 75%, its energy-saving effect highly significant.
2. non-scaling, can keep efficient state for a long time.Under general shower flow condition (4.3L/min), its cold and hot matchmaker's wing passage cross-sectional area little (2mm * 50mm), and heat-transfer surface is big, so its cold and hot matchmaker's flow velocity high (71.7cm/s).Add smooth surface (mirror face stainless steel material), heat medium temperature is the critical-temperature of scleroma dirt of water (be significantly less than 60 ℃) only below 40 ℃.General knowledge is told us, forms the fouling chief reason to be: rough surface, low, the overcritical fouling temperature of flow velocity etc.Therefore spiral antiscale heat exchanger of the present invention can not take place to stop up and lose efficacy because its unique design and structure have solved scale problems well, can guarantee to move efficiently for a long time.
Heat exchanger by above-mentioned technology is made not only has significant heat exchange efficiency, and has solved the fatal drawback that very easily forms the soft junction dirt because of the waste water quality difference well.Therefore the present invention has fundamentally solved the prior art scale problems, can guarantee permanently effective reliability service, complete ability industrialization aquatic products product, and technical performance is good, realizes its using value.
