Summary of the invention
According to the present invention, it is proposed that a kind of Straight-through heater, there is one for heating through-flow liquid The heat exchanger of body, described heat exchanger has one for the domestic water inlet connecting cold water pipeline With one for connecting the domestic water outlet of hot water line, wherein, it is provided with one for controlling or adjusting The control device of the temperature of joint liquid, wherein, arranges a temperature sensing on this domestic water inlet Device, wherein, described control device is configured to by the temperature sensor on this domestic water inlet The detection temperature when hot water is discharged and detect this domestic water inlet and be in the temperature in moment after a while, Additionally, this control device is configured to identify in the case of at this domestic water inlet, temperature raises Liquid exports to the through-flow direction of this domestic water inlet from this domestic water, and regulates this life subsequently Apply flexibly the temperature at water inlet.
According to the present invention, it is also proposed that a kind of for running according to the through type described in technique scheme The method of heater, this Straight-through heater have one for the heat exchanger heating through-flow liquid, Wherein, obtain the liquid through-flow direction by heat exchanger, wherein, realize liquid according to through-flow direction Actual temperature to the regulation of predetermined rated temperature.
The task of the present invention now, even if still being able to realize Straight-through heater when joint miss change Run.
According to this task of the present invention by having the Straight-through heater solution of feature in technique scheme Certainly.Favourable expanded configuration is drawn by the description below.
Can be with liquid by heat exchanger by temperature sensor layout on domestic water inlet Through-flow direction independently, i.e. with cold water pipeline is arranged on domestic water outlet and is also provided in domestic water On entrance and correspondingly hot water line is arranged on domestic water inlet and is also provided in domestic water and goes out Heated liquid is independently discharged on mouth.Variations in temperature on domestic water inlet allows to release, liquid Body is discharged or draws.Such water vent is referred to as drawing.If temperature sensor here it is shown that life Apply flexibly the temperature on water inlet to rise, then it means that hot water line is arranged on domestic water inlet On, i.e. heat exchanger is being flow through to the through-flow direction of domestic water inlet from domestic water outlet.Cause This, the liquid of output or the control of the temperature of heat exchanger or regulation are surveyed according on domestic water inlet The actual temperature obtained is carried out.Turn off at this properly functioning from domestic water inlet to It is set thus Straight-through heater is transported in error running on the through-flow direction of domestic water outlet OK.
Generally at this, temperature sensor is set in domestic water outlet.In domestic water outlet Such temperature sensor is when hot water line and cold water pipeline correctly connect, from domestic water inlet For detecting the actual temperature in hot water line and thus using when the through-flow direction of domestic water outlet In the heat controlled or regulation is delivered on liquid by heat exchanger.The temperature exported by domestic water Degree sensor runs at this and improves wrong identification further.Domestic water inlet and domestic water exit The comparison of temperature provide reliablely and be connected to domestic water inlet about cold water pipeline and still give birth to Apply flexibly the information on water out.If the temperature at domestic water inlet exceedes domestic water exit Temperature, then there is the miss change of joint, thus Straight-through heater should run in error running.
Preferably a flow sensing is set on domestic water inlet and/or in domestic water outlet Device.Such flow transducer exists in the most traditional Straight-through heater, wherein, by stream Quantity sensor obtains output, and this output is for controlling the heat being delivered on liquid by heat exchanger Amount.Such flow transducer is only the most reliable, wherein, according to the present invention on through-flow direction at this It is raw that the directional dependency of through-flow sensor can be equally used for identifying whether cold water pipeline is correctly connected to Apply flexibly on water inlet and whether hot water line is correctly connected in domestic water outlet.Although if Temperature at domestic water inlet improves but flow transducer does not provide any signal, does not the most send out Go out the signal discharged, then there is the connection of obvious miss change, thus Straight-through heater must be in mistake Running in operation, the regulation of the liquid wherein discharged is carried out according to the temperature at domestic water inlet.
In the preferred expanded configuration of one, heat exchanger has a secondary with pump and thermal source and returns Road, they can control by controlling device.The torrid zone that will be produced by thermal source by secondary loop and pump Enter in heat exchanger and be delivered to therefrom on liquid such that it is able to adding thermally drain.Heat Source can have different configurations at this, such as, as gas burner or oil burner or add as electricity Thermal element is constituted.It is also recognized that secondary loop is such as configured to the part of central heating system.
Preferably control device and there is a memorizer, wherein can store following state:
0: need to check,
1: properly functioning,
2: error running,
Wherein, the operation of Straight-through heater is carried out according to the state of storage.In order to store corresponding shape State, needs a byte at this, and this has the advantage that relative to the storage in simple binary digit, I.e. it is less susceptible to erroneous effects.Straight-through heater the first start in other words of initialization first it Before, store in memory at this: need to check.Therefore ensure that, laggard reconnect every time Row checks: hot water line whether be correctly connected to that domestic water outlet is upper and cold water pipeline the most just Really it is connected on domestic water inlet.If answer is affirmative, then Straight-through heater is just Work in often running and this state is stored in memorizer.In properly functioning, pass through user Different settings, such as Straight-through heater can be carried out run in economic model or comfort mode. In order to save energy in economic model, when not having liquid to be drawn, it is allowed to heat exchanger is the biggest Cool down in degree.In error running, i.e. it is connected on domestic water inlet and cold as hot water line When water lines is connected in domestic water outlet, can not run in economical operation on the contrary, because in mistake Should be attached in running reexamines by mistake, and this is only when heat exchanger is at a temperature range of operation It is only possible to during middle operation.It is likely in error running be limited by other setting probability of user System.
Preferably control device to be designed in this wise so that when hot water line is connected on domestic water inlet The liquid of intermittent fever can obtain on domestic water inlet and a display display mistake is transported when needed OK, wherein, the especially temperature of heat exchanger is enhanced or keeps constant, or according to domestic water Temperature in entrance is conditioned.Even if being thus capable of Straight-through heater when the miss change of joint Enough operations.By arranging corresponding display, installation personnel can be found out faster and eliminate Error reason.But it is in addition to eliminate outside mistake, it is not necessary to make Straight-through heater stop.But it is permissible Realize restricted operation.
This task is solved by the method with feature in preceding solution according to the present invention.
Here, obtain the liquid through-flow direction by heat exchanger, wherein, realize according to through-flow direction The actual temperature of liquid is to the regulation of predetermined rated temperature.Straight-through heater not only can be from life Apply flexibly water inlet in the through-flow direction that domestic water exports, i.e. at hot water line and cold water pipeline just When really connecting and can transport in the contrary through-flow direction of domestic water inlet from domestic water outlet OK.Here, different regulation parameters can be used according to through-flow direction.Such as, rated temperature is permissible Exporting in the through-flow direction of domestic water inlet by the most predetermined from domestic water, and specified Temperature can changed by user in the correct through-flow direction that domestic water exports from domestic water inlet Become, such as by selecting economic model.
Advantageously, through-flow direction is right by combining the temperature survey at domestic water inlet when needed The temperature survey in domestic water exit and/or combine in domestic water inlet or domestic water outlet Flow transducer is obtained.It is that hot water line is connected to domestic water that temperature at domestic water inlet improves Mark on entrance, i.e. through-flow direction lead to domestic water inlet from domestic water outlet.But mistake Identification can be the most more reliable, the most also detects the temperature in domestic water exit.If it is raw Apply flexibly the temperature when drain relative to domestic water exit of the temperature at water inlet to improve, that Obviously occur from through-flow to domestic water inlet of domestic water outlet.Depend on that the flow in direction passes Sensor is equally used for obtaining through-flow direction.But in order to regulate the actual temperature of the liquid of discharge, It is also required to detect the temperature at domestic water inlet.
On domestic water inlet, preferably measure temperature T1 and measure in domestic water outlet One temperature T2, wherein, when temperature T2 is higher than temperature T1, is adjusted to specified temperature by temperature T2 Degree, and when temperature T1 is higher than temperature T2, temperature T1 is adjusted to rated temperature.The most not only examine Survey the temperature at domestic water inlet and detect the temperature in domestic water exit.The basis of regulation exists This this hottest detection temperature, it reliably provides the through-flow direction about internal heat exchanger Situation.If temperature T2 in domestic water exit is more than temperature T1 at domestic water inlet, that Exist properly functioning, and if temperature T1 at domestic water inlet is higher than domestic water exit Temperature T2, then there is error running.Depending on there is properly functioning or error running, control dress Put and can be run in different patterns in other words by different programs.
At this it is particularly preferred that store one of three below state in a memorizer:
0: need to check,
1: properly functioning,
2: error running,
Wherein, when Straight-through heater initializes and/or when longer downtime, memorizer is set to Position is " 0 ", wherein, especially repeats the inspection to through-flow direction in error running.At delivery shape In state, i.e. before the initialization first or first start of Straight-through heater, store in memory Need to check.Therefore check when first start, see that hot water line and cold water pipeline are the most correct Be connected.Add heat-heat exchanger for this and detect the temperature at domestic water inlet.When needed Additionally detect the temperature in domestic water exit and compare with the temperature at domestic water inlet.Also It is contemplated that detect whether to carry out liquid discharge by flow transducer.If domestic water inlet now The temperature at place, higher than the temperature in domestic water exit, stores, Straight-through heater the most in memory Error running works.If the temperature in domestic water exit is increased beyond at domestic water inlet Temperature, then storage, Straight-through heater is in properly functioning middle work.In error running, This user sets and is the most reliably limited, and wherein, such as can not realize during this operates in economic model, Thus do not carry out the unnecessary cooling of heat exchanger.Specify in error running at this, carry out through-flow direction The inspection updated periodically.
Preferably keep in error running at this temperature of heat exchanger temperature upper limit and lowest temperature it Between.This can such as be carried out by Fuzzy tuning.
Preferably use ratio at properly functioning middle high rated value in error running.Thereby guarantee that, even if The liquid of enough heat is also arranged by the incorrect connection of cold water pipeline and hot water line from heat exchanger Go out to hot water line.Wrong identification is improved at the same time by the rated value improved, because rated value Improve and cause the temperature of the increase when drain to improve.
Accompanying drawing explanation
The present invention combines accompanying drawing below with respect to a preferred embodiment and is described in detail.There is shown:
Fig. 1 illustrates the schematic diagram of Straight-through heater;With
Fig. 2 illustrates possible method flow.
Detailed description of the invention
Figure 1 illustrates a Straight-through heater 1 with heat exchanger 2, wherein, heat exchanger 2 have a domestic water inlet 21 and a domestic water outlet 22.Thermal source 52 produces Heat energy flows to heat exchanger 2 by a secondary loop 5.Here, heat energy is handed over from thermal source 52 to heat The transmission of parallel operation 2 is carried out by liquid, especially water, and it is driven by pump 51.
When correctly installing, a cold water pipeline 31 is arranged on domestic water inlet 21 and one Hot water line 32 is arranged in domestic water outlet 22.By the through-flow direction of heat exchanger 2 then Carry out towards hot water line 32 from cold water pipeline 31.Here, realize in heat exchanger 2 heat energy to The heating of the transmission of liquid, i.e. liquid, liquid is discharged on hot water line 32 heatedly.Below Assume: use water as liquid, wherein, however it is also recognized that the liquid using other.
The heat energy of water can be delivered to by heat exchanger 2 control device 4 by one and regulate.Generally at this Detect output by a flow transducer 8, wherein, control device and determine in heat according to output Exchanger 2 must transmit how much heat.The heat energy brought into by secondary loop 5 is the most defeated Send.When cooling water pipeline and hot water line correctly connect, i.e. when through-flow direction is from domestic water inlet To domestic water outlet carry out time, a kind of such control device functions satisfactorily.By temperature The regulation of sensor 7 can realize the regulation of rated temperature at this, and this temperature sensor is arranged on life With on water out 22.
On contrary through-flow direction, i.e. when in wrong way cold water pipeline 31 be connected to domestic water In outlet 22 and time hot water line 32 is connected on domestic water inlet 21, flow transducer 8 is right And the temperature sensor 7 that no longer output signal and domestic water export on 22 the most only shows constant Temperature, the temperature of the cold water i.e. inputted.The most at this moment the controlled discharge of hot water can not be realized.
Specify now according to the present invention, domestic water inlet 21 arranges a temperature sensor 6. Such temperature sensor 6 is in correct connection, i.e. from the outlet of domestic water inlet 21 to domestic water 22 through-flow direction time, there is other control function, on domestic water inlet 21, i.e. detect pre-add The water of heat.Such as in order to determine that the water of solar energy preheats.Once the water temperature at domestic water inlet 21 exists Domestic water exports more than the water temperature at 2, then straight flow heater 1 its thermal source 52 in other words is not swashed Live.Additionally, temperature sensor 6 may be used for by regulation in advance, i.e. considering water inlet temperature In the case of optimize domestic water export the water temperature at 22.But it is capable of the reliable of through-flow direction The regulation of the rated temperature of the liquid determined and export, even if hot water line is connected to domestic water inlet Time on 21, when i.e. straight flow heater 1 is flow through mistakenly.
When correctly connecting, i.e. it is connected on domestic water inlet 21 and hot water at cold water pipeline 31 Pipeline 32 exists a kind of properly functioning when being connected in domestic water outlet 22.When heat exchanger 2 exists When contrary side runs up, i.e. it is connected in domestic water outlet 22 and heat when cold water pipeline 31 When water lines 32 is connected on domestic water inlet 21, there is a kind of error running.At this in display Device 9 can show, if there is error running, thus such as by being identified immediately by installation personnel, Whether hot water line 32 and cold water pipeline 31 are correctly connected on heat exchanger 2.
Schematically illustrate a kind of possible flow process of the method according to the present invention in fig. 2.Pacify first After dress, i.e. when the load operation first of Straight-through heater 1 or after long-time interrupt run, Heat exchanger 2 is initially heated.The temperature at domestic water inlet 21 is detected when discharging hot water.? When needing, thermal source 52 can provide more heat now, and wherein, detection domestic water enters the most continuously Temperature at mouth 21.Before thermal source 52 starts temperature at domestic water inlet 21 with detect after a while Temperature compare.When occurring that temperature improves, through-flow direction is used towards life from domestic water outlet 22 Water inlet 21 realizes, and i.e. there is error running.Therefore go out to discharge hot water also at domestic water inlet 21 And the actual temperature at domestic water inlet 21 is adjusted.Although thermal source 52 provides heat energy to arrive heat Exchanger 2, but if the temperature at domestic water inlet 21 declines, then cold water pipeline 31 and heat Water lines 32 is properly connected and realizes properly functioning, and wherein hot water exports 22 at domestic water It is discharged, thus the temperature that domestic water exports at 22 is adjusted to rated temperature.
The Straight-through heater 1 heating when load running first is independently carried out with situations below at this, I.e. which pattern of Straight-through heater 1 is set, i.e. for example whether have selected economic model, at warp In Ji pattern, the heating of heat exchanger 2 is carried out the most when needed.
If being also carried out now domestic water outlet in addition to the temperature detection at domestic water inlet 21 Temperature detection on 22, then determine through-flow direction simply by the comparison of two temperature is comparable. If domestic water exports the temperature at 22 and exceedes at domestic water inlet 21 during drain Temperature, then Straight-through heater be positioned at properly functioning in.If the temperature at domestic water inlet 21 When exporting the temperature rising at 22 relative to domestic water on the contrary, then Straight-through heater 1 is positioned at mistake In operation.Wrong identification can be at this additionally by arranging a flow transducer improvement.
