High efficient heat exchanging district, center, shown in 5.3 among Fig. 5, the section of this sectional view is the center of heat exchange jar; The heat exchange that crosses of life moisturizing and two strands of current of circulating hot water; Heat exchange efficiency is the highest, because the resistance of liquid in the tank body, makes under the effect of hydraulic pressure at the back of water resistance that two strands of current that arrive the position, center receive direction of advance and current itself; Water flow section is long-pending to become big; Along with near under separately the delivery port and mouth of pipe action of negative pressure, water flow section is long-pending to diminish again gradually, returns to suitable with the caliber of water inlet pipe.
A end poor efficiency heat transfer zone, shown in 5.4 among Fig. 5, the section of this sectional view is identical with the operating mode of B end poor efficiency heat transfer zone.
A holds invalid heat transfer zone, and shown in 5.5 among Fig. 5, the section of this sectional view holds the operating mode of invalid heat transfer zone identical with B.
The cross-section analysis method further specifies, and the pressure-bearing heat accumulating type heat exchange jar with symmetrical balance formula air deflector is than common pressure-bearing heat accumulating type heat exchange jar, and the area of the heat exchange that crosses more greatly, longer heat exchange zone and heat transfer process, higher heat exchange efficiency are arranged.
The result of above-mentioned two kinds of analyses can clearly see; Pressure-bearing heat accumulating type heat exchange jar with symmetrical balance formula air deflector is than common pressure-bearing heat accumulating type heat exchange jar; Under the condition in equal length useful storage district; The length of its effective heat transfer zone is respectively 1073.7mm and 435.3mm, differs 2.47 times, and quite the former has increased by 2.47 times than the latter's heat exchange area; The heat exchange that crosses of the former maximum 80 strands of weeps; The latter has only the heat exchange that crosses of two big strands of current; The former is 10 times of the latter at the average equivalent heat exchange area of effective heat transfer zone; If the big strand current heat of the latter concentrate, heat transfer temperature difference is big, utilize jar in liquid convert as latter's equivalence heat exchange area as various heat exchange factors of converting such as heat transferring mediums; The result is that the pressure-bearing heat accumulating type heat exchange jar with symmetrical balance formula air deflector also should maintain 5 times advantage than the actual heat exchange area of common pressure-bearing heat accumulating type heat exchange jar.
Remove above-mentioned analysis advantage, the pressure-bearing heat accumulating type heat exchange jar with symmetrical balance formula air deflector also has when the decline of heat exchange jar useful storage section length, and its effective heat transfer zone length descends and do not follow the decline ratio of useful storage section length.
Example 1: heat exchange jar useful storage section length is 3500mm, and effectively heat transfer zone length is 1074mm, and effectively heat transfer zone length is 30.68% of useful storage section length.
Example 2: heat exchange jar useful storage section length shortens to 2500mm, and effectively heat transfer zone length is 862mm, and effectively heat transfer zone length is 34.38% of useful storage section length, and obviously the lifting of this ratio value helps the maintenance of heat exchange efficiency; If compare with the data of example 1, then useful storage section length phase ratio 1 is to have descended 28.57%, but effectively the length of heat transfer zone has only descended 19.72%, and rate of descent is 69.02%.
Example 3: the effective section length of heat exchange jar retaining shortens to 2000mm, and effectively heat transfer zone length is 685mm, and effectively heat transfer zone length is 34.25% of useful storage section length, and obviously this ratio value is similar with example 2; If compare with the data of example 1, then useful storage section length phase ratio 1 is to have descended 42.86%, but effectively the length of heat transfer zone has only descended 36.2%, and rate of descent is 84.46%.
The clear demonstration of above-mentioned analysis; When the length of heat exchange jar shortens with 25.87% and 34.25% amplitude; The length rate of descent of its effective heat transfer zone is respectively 69.02% and 84.46%; This index has disclosed limited application scenario, space, uses this pressure-bearing heat accumulating type heat exchange jar with symmetrical balance formula air deflector, still can obtain higher heat exchange effect.Conversely; The length of keeping the heat exchange jar is constant, but when increasing the diameter of heat exchange jar, owing to can increase the diameter of symmetrical balance formula water diversion disk synchronously; Therefore just can increase the quantity of balanced type mozzle, finally can increase heat exchange area whereby and improve heat exchange efficiency.
The operating mode of embodiment is isolated heat exchange with the condensed water of water-water heat pump with the life moisturizing through plate type heat exchanger earlier, and then through pressure-bearing heat accumulating type heat exchange jar, is adopted life moisturizing and circulating hot water reverse heat-exchange, produces 55 ℃～57 ℃ domestic hot-water.Because the heat of water-water heat pump is from condensed water, its highest temperature also has only 60 ℃, and the operating mode of standard is 5 ℃ of Inlet and outlet water temperature difference; But flow is very big; The flow of specified 1230kw heating capacity is 211 tons/hour, therefore can't use the heat exchanger as that type high temp low discharge of volumetric heat exchanger, owing to adopted the enclosed water system; Rate of water make-up just equals use amount; For adopting motor-driven water-water heat pump to use in this type systematic, be easy to be absorbed in the unfavorable operating mode of frequent starting, just avoid as far as possible or reduce the operating mode that frequency changes startup occurring so must have suitable heat storage capacity.
And the maximum problem of the practical effect of common pressure-bearing heat accumulating type heat exchange jar is that heat exchange efficiency is low; Heat transfer temperature difference (is just protected shutdown when being lower than 1.5 ℃ of water-water heat pumps) all the time between 3.2 ℃～1.5 ℃ in heat transfer process; And hot water supply water temperature unsettled fluctuation of short time between 53 ℃～57 ℃; All these data are all pointed to the deficiency that this kind heat exchange mode exists, and therefore, it is just necessary to assurance heat exchange efficiency, assurance hot water quality to improve the heat exchange effect of improving this heat exchange jar.
Through in pressure-bearing heat accumulating type heat exchanger, installing symmetrical balance formula deflector additional; Shunting action by AB two ends symmetrical balance formula water diversion disk and balanced type mozzle; And belong to the drainage at the tubaeform receipts mouth of a river in water route separately; Be implemented in the identical heat exchange jar,, become the reverse heat exchange that crosses of 160 strands of weeps by the reverse heat exchange that crosses of two strands of big current; Heat exchange efficiency significantly improves, the even distributed degrees of delivery port heat is significantly improved; Finally be reflected under the same demand environment, the temperature difference in the heat transfer process remains on (leaving water temperature is shut down greater than 57 ℃ of water-water heat pumps, rather than the temperature difference is lower than 1.5 ℃ overvoltage protection shutdown) between 4.2 ℃～3.1 ℃.The delivery port temperature remains on and keeps long steady working condition (the high-temperature steam valve that is lower than 53 ℃ of volumetric heat exchangers is opened by steam and heated) between 57 ℃～54 ℃; The decline of outlet temperature is due to rate of water make-up increase and backwater amount add up; Its downward trend is stable slowly, and water-water heat pump starts when being lower than 54 ℃ when dropping to.
The present invention adopts hotel, hotel, the apartment of enclosed water system applicable to all; Adopt the reducing energy consumption of heat pump heat recovery application technology and other all kinds of Waste Heat Recovery application technologies; And the enclosed water system in newly-built hotel, hotel, apartment, adopt heat pump heat recovery application technology and other all kinds of Waste Heat Recovery application technologies.
