Description

The recirculation shower system
Technical field
The present invention relates to a kind of recirculation shower system.Particularly, the present invention relates to a kind of recirculation shower system, the energy in this recirculation shower system transmits in recirculation circuit by one or more heat pumps.
Background technology
The recirculating system of known water is used for many application.For example, shower is arranged in shower water be recycled, thereby uses water still less.The recirculation shower is mainly used in the portable and movable application, for example is used for ship and camper.For example, US4,828,709 have described a kind of recirculation shower system that is used on ship and the station wagon.Recirculating water system moves water, and this water is from the non-tap water supply on ship or the vehicle (non-mains water supply), and this recirculating water system comprises the holding vessel of filter, water heater and fresh water and used water.
Many places in the world, the water supply anxiety, and taked the supply of some measures with assurance water, and the regular incentive citizen of government reduce the use amount of water.
In domestic. applications, the problem of using the recirculation shower to bring is that any water that requires to mix with running water must satisfy the regulation of the purity rubric of water, and does not satisfy the purity rubric of water from the waste water of shower ejection.
Normally used domestic shower is divided into two classes, i.e. electric shower-bath and mixing shower.
Usually, electric shower-bath is pump up water from cold main water supply only, and as required water is heated to required temperature.Therefore, such shower can not exhaust hot water and stable water temperature can be provided.They also have such advantage, and promptly they are easy to install relatively, because they do not need specific piping facility, only need cold feed.
Available peak power is 7.5kW to 11.5kW from the standard household electric power of 240 volts (for example in Australia and whole Europe) power supply, and this has limited and can be used for power that the water through the bath heating device is heated.In order to obtain enough the shower of heat, be necessary to limit the flow velocity of water, be restricted to maximum rate usually and be 5 and rise to 6 Liter Per Minutes.Obviously, be to serve as to sacrifice just can realize higher flow velocity under lower temperature only with the shower water that is provided.Some places in the world, because available peak power is lower than 7kW, therefore make this problem become more serious, for example in some zones of China, available peak power is 3kW, and this finally makes electric shower-bath because the water flow velocity that heated is extremely low and unavailable.
Mix by the water that uses valve from hot water and cold feed, to take out, mix shower and reached required water temperature.Mixing shower not only needs the hot water supply but also needs cold feed, therefore obviously needs thermal water source, for example hot-water cylinder or combination boiler or multiple spot water heater.Therefore, mix shower and need more complicated piping facility than electric shower-bath.In addition, if it is discontinuous to supply water, for example because there are other people drawing hot water, then the temperature of shower will change.
Yet, mix shower and can realize higher water flow velocity than electric shower-bath, and more cheap than electric shower-bath.
Powerful shower is to mix a kind of modification of shower and comprise a pump.
WO2006/131743 has solved some above-mentioned problems by a kind of shower system that recycles is provided, wherein the water in the shower is collected in the shower pallet (shower tray), recycle by pump, and purify, filter then, drive at electricity and carry out pasteurization in the heater, mix with cold fresh tap water and carry back shower head by hydrocyclone, repeat this circulation then.
Yet although this system reaches 70% than traditional shower is energy-conservation with water saving, it has many shortcomings, comprising:
It is the shower of 10 liters of/minute water that heater need provide flow velocity up to the power of 9kW.In developed country, this will need directly to be connected to from fuse/circuit breaker box the power source special supply of the 240v and the 40Amps of shower.This is very expensive and install and to have destructiveness.In developing country, this has bigger power than the power that is fed to the house via domestic power supply, and making shower system is infeasible in those countries.
The recirculation percentage of the water that this system realized depends on the environment water temperature of the cold water of being supplied; The cold water of input is warm more, and the water that can recycle is then few more.In very hot country in summer, this means that recirculation percentage can reduce to from 70% and have only 50%.
Overcome these weakness will make original shower economize on water more, more energy-conservation, more cheap and be easier to install, operation gets up more cheaply, and can use for the people more than millions of.
Summary of the invention
In one form, although need not be unique form or be actually the wideest form, the present invention relates to a kind of recirculation shower system, this recirculation shower system comprises: shower head and shower pallet, loop, this loop configuration used water that becomes to be used to collect from the shower pallet, and making the used water of at least a portion be recycled to shower head for further use, this loop comprises at least one heat pump so that carry out heat exchange between the water of relatively hot and cold relatively water.
In another form of the present invention, a kind of recirculation shower system is provided, this recirculation shower system comprises: shower head and shower pallet, loop, this loop configuration used water that becomes to be used to collect from the shower pallet, and making the used water of at least a portion be recycled to shower head for further use, this loop comprises: cyclone hydraulic separators; Be positioned at the filter in separator downstream; Be positioned at the heat exchanger in filter downstream; At least one heat pump is used for carrying out heat exchange between the water of relatively hot and cold relatively water; Heating unit is used for when described recirculation water is heated this recirculation water being remained to pasturisation temp; And blending tank, be used for relatively hot being mixed with relative cold water in described shower head upstream.
(a plurality of) heat pump that uses in system of the present invention is a conventional heat pump as known in the art.Heat pump is the system that heat is sent to another position from a position.Using two kinds of common example of heat pump is refrigerator and air-conditioning.Heat pump is by coming work with the gas pump around the sealing system by two positions.Allow gas to expand at the primary importance place, this makes primary importance cooling and anything draw heat around it.Gas is compressed at second place place, and this produces heat, and this position is gone in heat radiation subsequently.Therefore, the heat that obtains from primary importance moves to second place place.The temperature at primary importance place reduces, and the temperature at second place place raises.
Drive that the required energy of heat pump only need compress and the circulating heat pump loop in gas.This makes heat pump extremely effective, because for being used for for every Joule energy of driving pump, system will make 3 to 6 joules heat energy move to the second place from primary importance.
Therefore, in fact the heat pump with 3 kilowatts of inputs will move the heat energy of (output) 9 kilowatts to 18 kilowatts.
The liquid of Shi Yonging can be any liquid that uses in egr mode in the present invention, and in this egr mode, liquid need heat and/or cool off for use.
With reference to the form of the invention described above, by transmit existing energy effectively in system, energy recirculating system of the present invention has reduced energy requirement, thereby has produced the system that a kind of needs minimum (if any) additional heat energy is input to system.
Heat pump is provided with by this way, makes all to have cooling circuit in the waste water outflow of input of the cold water of system and system, and have heating circuit in the position of the electric heater of original design.
Thereby, this system:
Remove heat energy from the cold water input, control and reduction are fed to the temperature of intrasystem fresh cold water, and make water recirculation percentage maximize.
From the waste water of delivering to sewer, remove energy, thereby reduced energy dissipation.
To be transferred to heating unit from the energy of cold water input and waste water output.
In order to make the present invention be easier to understand and implement,, only one or more preferred embodiments are described by example now with reference to accompanying drawing.
Description of drawings
Fig. 1 is the schematic diagram that the present invention recycles shower system.
The specific embodiment
Provide the present invention use in recirculation shower system (for example described in the WO2006/131743) one detailed, non-limiting instance.
With reference to Fig. 1, in shower system of the present invention, running water (1) is introduced in the system via the water pipe that passes hydraulic jump (3) (2), and is pumped through the cold water inlet (5) of shower mixer (6) by pump (4), and wherein hydraulic jump (3) has prevented that water from turning back to the running water from system.This blender is regulated the cold relatively current and the current of relatively hot, till mixed flow reaches the required temperature of shower.This will discuss in more detail below.
Mixing water is transported to bypass valve (7) from blender, and this bypass valve (7) can guide shower water:
Enter shower head (22) by pipeline or flexible pipe (21), or
Enter bypass loop (8).
When shower was opened, bypass valve was set to lead water to bypass loop (8) automatically, water was shifted away from shower head (22), so that before not reaching predetermined temperature and user and also not pressing start button, do not make water.If this has prevented during temperature is set or any type of water waste of user when not using shower immediately after opening shower.
When bypass valve was set to that water is directed to shower head, shower water was collected in the shower pallet (23) that inlet nozzle (24) is housed, and nozzle (24) is connected to water pipe (25), and water pipe (25) is connected to recirculation circuit pump (27) by water pipe (26).In order to prevent that recirculation circuit is blocked, the inlet (24) that leads to recirculation circuit is covered by filter screen or the net similar to employed design in the mineral spring outdoor bathing place.
When bypass valve was set to carry out bypass, water was transferred to recirculation pump (27) via water pipe (8) and (26).
Recirculation pump (27) is delivered to hydrocyclone (10) by water pipe (9) with water pump.The purposes of hydrocyclone is dual:
Remove the suspended solid less than 2mm from shower water, this has prolonged the life-span of filter (14).Hydrocyclone is by making water rotation carrying out work; Force anyly than the outside of the heavy particle separation of water to hydrocyclone, particles settling is to the bottom there, and by underflow (underflow) (11), in the outlet of the bottom of hydrocyclone they are taken away.Forcing, the water of cleaning upwards enters overflow (overflow) (13) by the vortex finder (vortex finder) that is in the hydrocyclone top.Hydrocyclone is transported to underflow with 30% water usually, and 70% water is transported to overflow.
Owing to reduced by 30% recirculation volume, hydrocyclone must need to introduce again new cold running water.The introducing of cold water allows the water of recirculation to be heated above the required temperature of shower, because cold water can reduce the temperature of the hot water in the blender.Therefore, this allows the water " overheated (overheated) " of recirculation to reach 72 ℃ pasteurizing temperature, and this is enough to kill Legionella (Legionella) and other pathogen.
Water enters filter (14) from hydrocyclone overflow (13), and filter (14) is removed chlorine, any residual particles of not removing as yet and any shampoo and the soap in the water.
Water enters heat exchanger (16) from filter (14) by water pipe (15).Heat exchanger comprises two loops:
" cold " loop, from filter (14) lead to thermoregulator (17) and heating unit (18) and
" heat " loop turns back to shower mixer (6) from heating unit (18) and thermoregulator (17) by water pipe (19).
The function of heat exchanger is to improve the temperature of the water that flows to heating unit, and this has reduced the live load that may be present in the heater in the heating unit, and another function is that the temperature that will flow to the water of blender is reduced to the more approaching temperature that is suitable for carrying out shower.
The current that come automatic heat-exchanger (16) are through temperature and flow regulator (17), the temperature and the flow of this temperature and flow regulator (17) monitoring water, at least be enough to water is carried out pasteurization (72 ℃) with the temperature of guaranteeing to reach, but be lower than the level that can cause excess pressure in the heating unit by heating unit.
In WO2006/131743, heating unit comprises the thermal resistance heater.In the present invention, this hot loop by heat pump A (32) and heat pump B (31) replaces or replenishes.Container and two hot loop combinations are to form point of heat transfer (34), wherein, thermal-arrest point (30) and thermal-arrest point (33) hydrocyclone underflow (11) on the heat energy locating collect of heat pump A﹠B on cold inlet loop is transported in the recirculation shower water, is used for water temperature is risen to 72 ℃.
From heating unit/point of heat transfer, the hot shower water of recirculation turns back to the heat inlet (20) of shower mixer (6) via water pipe (19) by the hot loop of heat exchanger (16).In blender (6), temperature sensor (29) is monitored the temperature of cold inlet (5) and heat inlet (20), information is sent to CPU (28), and this CPU (28) is adjusted flow to locate to provide the water of required shower temperature at shower head (22).
Hydrocyclone (10) is removed heavier particle and is shunted from water, make carry major part not about 30% current of dissolved solid leave by underflow (11).This part water still leaves the energy that the form with heat from original shower exists.Usually, the temperature of this water is about 40 ℃.This water is fed among the recuperation of heat jar A (33).Heat pump A (32) is transported to pasteurization unit (34) with the residual amount of energy of the water among the recuperation of heat jar A (33).In case energy reclaims, just be discharged to drainpipe (12) from the cooling water of recuperation of heat jar A (33).
Water from the surplus of hydrocyclone (10) cleans at this moment, and discharges by the top of hydrocyclone overflow (13).
Then, clean water is transferred into filter (14), and in its cleaning that visually becomes of there, and chlorine is removed.
At this moment, water is visually clarified, but must carry out 15 seconds sterilization under 72 ℃ temperature.
Therefore, at carbon filter (14) afterwards, water enters heat exchanger (16).Heat exchanger is increased to about 55 ℃ with water temperature from about 41 ℃.This has just reduced the required energy input that reaches pasturisation temp, and has increased the efficient of shower.
Simultaneously, fresh cold water is pumped among the recuperation of heat jar B (30).The energy that reclaims from this jar by heat pump B (31) also is fed in the pasteurization unit (34).The energy that is provided to pasteurization unit (34) by heat pump A (32) and B (31) should be in most of the cases to be enough to make the enough energy that do not need heating element heater in pasteurization unit (34).This is the aspect of the present invention bigger and significant conserve energy and cost.
In system of the present invention, heat pump A and B can replace with the single heat pump with 2 loops.
In mixer unit (6), the hot water of recirculation and cold fresh tap water are mixed, have temperature required shower to provide.Fresh water has also replaced the amount of the water of loss from the underflow of hydrocyclone (10) (11).
At the mixer unit of flowing through (6) afterwards, water is by bypass valve, and water can turn to (park mode) or be diverted to shower head (22) around shower in bypass valve, and the energy of system of the present invention and water circulation continue to carry out as mentioned above.
Describing the present invention substantially, the more details of some energy calculating aspects of relevant this embodiment of the present invention will be discussed below with reference to figure 1.
Thermodynamics and energy calculate
About the recuperation of heat jar A (33) that is used for the hydrocyclone underflow and the recuperation of heat jar B (30) of the cold water that is used to enter the mouth, the water of cold water inlet and down spilling water must be able to flow, but their temperature can be reduced to very near freezing point.Therefore, in any one of this two jars, any heat that surpasses 1 ℃ all can be considered " surplus " heat.
The energy content of " surplus " heat depends on the environment temperature of water, but supposes that shower is in inside, house, and the environment water temperature should be similar to the temperature in house itself so, and therefore, when the shower first start, the environment water temperature should be about 20 ℃.
If each jar holds 5 liters, this means that the every premium on currency in the recuperation of heat jar has the heat energy of " standby " 19 ℃.Specific heat of water is 4.2KJ/L, this means that per 5 liters of recuperation of heat jars comprise " standby " energy of 399KJ.Therefore, two recuperation of heat jars of combination hold the energy of 798KJ altogether, and this energy can reclaim by heat pump.
The requirement of the pasteurization of recirculation water again is owing to the water in the pasteurization unit need keep 15 seconds down at 72 ℃, so the size of pasteurization jar must be 1/4 (15 seconds is 1/4 minute) of 1 minute flow velocity.Flow velocity is 7L/min (flow velocity at supposition shower head place is that 10L/min and recirculation fraction (recirculation fraction) are 70%).Therefore, pasteurization unit (34) hold at least 1.75 liters with needs.For illustrative purposes, this has increased to 2 liters.
When system started, the water temperature in the pasteurization unit was assumed to be 20 ℃ equally, and in order to reach pasturisation temp, needs was increased to 72 ℃: i.e. the raising of 52 ℃/L.Required for this reason energy will be 2.0L * 4.2KJ/L * 52 ℃=436.8KJ.Should numeral and recuperation of heat jar A (30) and B (33) in " surplus " energy relatively, should " surplus " energy for the temperature that makes the pasteurization unit is increased to 72 ℃, be more than sufficient.
About heat pump A (31) and B (32), maintain 72 ℃ in order to make pasteurization unit (34) at run duration, heat pump A (31) and B (32) need and can carry enough energy to be under 72 ℃ with the flow of keeping it to pasteurization unit (34).Flow velocity is that 7.0L/min and temperature required maximum value added are 20 ℃.This needs the constant input of 7.0L/min * 20 ℃ * 4.2KJ/L=588KJ/min.This converts 35 to, 280KJ/h or 9.8 kilowatt-hours.CoP as for 3.0, this needs that about 3.3 kilowatts energy input is arranged in the heat pump, so that keep the operation of shower.
When starting, the energy that is transported to pasteurization unit (34) from recuperation of heat jar A (33) and B (30) is 436.8KJ, reaches 72 ℃.This need carry 218.4KJ from each recuperation of heat jar.This will make the temperature in each jar reduce by 10.4 ℃.
If be 9.8 kilowatts or 588KJ per minute to the maximum,, need the 436.8KJ/588KJ of a minute or 45 seconds so in order to reach pasturisation temp from the heat of heat pump output.
Suppose that the environment water temperature is 20 ℃ when beginning, the temperature of each recuperation of heat jar when shower starts is 10 ℃.At run duration, the flow by each recuperation of heat jar is 3L.This has 10 liters flow and 70% recirculation fraction with regard to hypothesis at the shower head place.Flow by each recuperation of heat jar equates, because the water that flows to from trunk line must equal to deliver to by the hydrocyclone underflow water of sewer.
The shower run duration is cold goes into current and is in 10 ℃ in order to keep, and the heat energy that draws from recuperation of heat jar B (30) must equal to be input to heat energy the jar by fresh running water.Suppose that the environment water temperature is 20 ℃, every premium on currency to jar introduce 42KJ (1Lx10 ℃ * 4.2KJ/ ℃/L).When the flow by jar is 3L/min, input will be 126KJ/min, and this is transported to pasteurization unit (34) and is 10 ℃ with the input temp of keeping from recuperation of heat jar B (30) to mixer unit (6).
Suppose heat pump during steady-state operation with maximum capacity work, then heat pump carries 588KJ/min to pasteurization unit (34).If 126KJ from recuperation of heat jar B (30), will draw the surplus of 462KJ/min from recuperation of heat jar A (33) so.
The water that enters recuperation of heat jar A (33) will have 41 ℃ temperature (shower temperature in this example is that 45 ℃ and known temperature losses in shower are 4 ℃), and water will flow with the speed of 3 liters of per minutes.Therefore, from this jar draw 462KJ/min will reduce temperature (462KJ/min/3.0L/min/4.2KJ/ ℃/L)=36.6 ℃, and therefore the water among the recuperation of heat jar A (33) will reduce to 5 ℃.
From above clearly as seen, the introducing of heat pump has been got rid of the use electronic component used water has been heated to pasturisation temp.This is very favorable, because compare with current available recirculation shower, the required energy consumption of shower of the present invention has further reduced by 65%.This has just produced the shower that a kind of use is less than traditional shower energy 10%.In addition, even under hot weather, heat pump also allows the water temperature that controls environment, and this makes the water yield that can recycle maximize.Equally, these pumps also allow to remove used heat from waste water to be abandoned under the situation of not introducing water once more.
Run through whole specification, its purpose is to illustrate preferred embodiment of the present invention, and is not the specific collection that limits the present invention to any one embodiment or feature.
In this manual, unless context has needs in addition, term " comprise (comprising) " and as " comprises " and versions such as " comprising " be interpreted as and refer to the group that comprises described integral body or integral body or step, but do not get rid of any other integral body or whole group.
