Three, summary of the invention
The device that domestic hot-water's draining energy is recycled, be that hot water draining recuperator is arranged on the drainpipe of cleaners and polishes or on the arterial drainage, the tube side of this recuperator is a drainage channel, shell side is a cold water channel, cold water and hot water draining reverse flow are carried out sufficient heat exchange thereby make between cold water, hot water.
Be the hot water drainage channel in the tube side, so tube side design satisfies the slope requirement and the flow area requirement of draining, satisfy the abundant heat exchange needs of gravity current fluid simultaneously.Shell side is a cold water channel, so shell side design satisfies the flow area requirement of cold water, satisfies the heat transfer requirement of cold water simultaneously.
According to above-mentioned requirements, characteristics in conjunction with the plumbing technology, designed washbowl with vertical mount type, horizontal mount type heat exchanger, kitchen sink (basin) straight line mount type, vertical mount type, horizontal mount type heat exchanger, bathtub or shower house mount type heat exchanger, arterial drainage mount type heat exchanger.Its structural representation is seen accompanying drawing 1-4.The arterial drainage type heat exchanger is applicable to the public place that uses hot water, as bathhouse, bath center, amusement on water center and swimming pool etc.
Hot water draining after the heat exchange cooling enters sewer.Cold water after heat exchange heats up, part return and use after heater heats again, and part is mixed directly use of back with hot water, and this has just constituted the hot again instant energy way of recycling of hot water draining.This mode and device have reduced the energy consumption and the hot water supply amount of heater, thereby realize purpose of energy saving.Cold water after heat exchange heats up all returns heater and heats the back use again, and this has just constituted the energy of the pattern of fever again way of recycling of hot water draining.This mode has reduced the energy consumption of heater, thereby realizes purpose of energy saving.Cold water after heat exchange heats up all mixes the back directly to be used with hot water, and this has just constituted the instant energy way of recycling of hot water draining.This mode has reduced the hot water supply amount, thereby realizes purpose of energy saving.In conjunction with the characteristics of plumbing technology, designed system's pie graph of three kinds of energy ways of recycling that washbowl, kitchen sink (basin), bathtub or shower house, arterial drainage use, see accompanying drawing 5-8.
Three kinds of energy ways of recycling respectively have characteristics, are applicable to different situations.When selecting for use, should produce the mode of hot water in conjunction with the supply water temperature of hot water, the occupation mode of hot water, the installation site of energy recycle device is determined with the relation with water spot position, heater locations.The hot water supply water temperature can be divided three classes: be the water heater of representative class with the gas heater, its hot water supply water temperature is generally about 40 ℃; With electric heater, solar heat device is the water heater of representative class, and its hot water supply water temperature can reach 85 ℃; General about 60 ℃ of central authorities' hot-water heating system hot water supply water temperature.With hot water draining and cold water heat transfer mean temperature difference is example for 7 ℃, and the different retracting devices of different-energy way of recycling, reached at the heat recovery rate of different hot water supply water temperatures are calculated, and sees attached list 1.
From subordinate list 1 as can be seen: the heat recovery rate of hot again instant energy way of recycling is the highest, can reach 43%, 48%, 30% respectively to the heat recovery rate of bathtub, washbowl, arterial drainage.This be because, when selecting this mode for use, by the cool water quantity maximum of heat exchanger, cold water temperature rise minimum, hot water or cold water's heat transfer temperature difference maximum, thereby heat output maximum.And its heat recovery rate and supply water temperature are irrelevant, and this is because no matter how the hot water supply water temperature changes, the cool water quantity by heat exchanger all equals its water consumption.The heat recovery rate of pattern of fever energy way of recycling improves near the hot water serviceability temperature more with the hot water supply water temperature again, when this connects the hot water serviceability temperature more because of the hot water supply water temperature, cool water quantity by heat exchanger is just big more, the cold water temperature rise is just more little, hot water or cold water's heat transfer temperature difference is just big more, thereby heat output is just big more.The heat recovery rate of instant energy way of recycling improves with the rising of hot water supply water temperature, when this raises because of the hot water supply water temperature, the mixed proportion of cold water is just big more, the cool water quantity that uses is just big more, cool water quantity by heat exchanger is big more, the cold water temperature rise is just more little, and hot water or cold water's heat transfer temperature difference is just big more, thereby heat output is just big more; Otherwise heat is returned rate and is reduced, and when the hot water supply water temperature equaled the hot water serviceability temperature, its heat rate of returning was zero, need not mix cold water this moment and use, and the cool water quantity by heat exchange is zero, does not realize that energy reclaims.As seen it is crucial correctly selecting the recuperation of heat mode.
