The present invention relates to a kind of through type heater, has a heat exchanger that is used for the through-flow liquid of heating, described through type heater has the domestic water entrance and a domestic water outlet that is used for being connected the hot water line that are used for connecting the cold water pipeline, wherein, be provided with a temperature controlling device that is used for control or regulates liquid.
The invention still further relates to a kind of for the such method that has for the through type heater of the heat exchanger of the through-flow liquid of heating of operation.
Background technology
The through type heater for example is used for the heating household water.At this, water flows to the through type heater by the cold water pipeline, is heated by heat exchanger and is discharged from by the hot water line in through type heater inside.Heat exchanger can directly be heated or be heated by the secondary loop at this.The term domestic water is usually understood and is for example comprised drinking water.
For the normal operation of through type heater, need correctly connect hot water line and cold water pipeline, namely the cold water pipeline is connected on the domestic water entrance and the hot water line is connected in the domestic water outlet.Usually this timed unit is according to the heat input of the amount control heat exchanger of discharging, and the amount of this discharge detects by flow sensor.Yet only when the desirable through-flow direction by heat exchanger is held, namely the cold water pipeline is connected on the domestic water entrance and hot water line when being connected to the domestic water outlet and going up, and flow sensor is just worked satisfactorily.When the joint miss change, the mistake that may cause discharging liquid is measured.Also possible is that flow sensor is not exported any signal fully, namely can not obtain and whether discharge liquid.
In traditional through type heater, the cold water pipeline is necessary being connected for normal operation with hot water line correct in domestic water outlet on the domestic water entrance.The discharge of heated liquid, especially hot water can not realize when the joint miss change usually.
Summary of the invention
Task of the present invention is now, even if still can realize the operation of through type heater when the joint miss change.
Through type heater according to the feature of this task of the present invention by having claim 1 solves.Favourable expanded configuration is drawn by dependent claims.
By temperature sensor the layout on the domestic water entrance can with the through-flow direction of liquid by heat exchanger irrespectively, namely with the cold water pipeline be arranged on the domestic water outlet also be arranged on the domestic water entrance and correspondingly the hot water line be arranged on also to be arranged on the domestic water entrance in the domestic water outlet and irrespectively discharge through heated liquid.Variations in temperature on the domestic water entrance allows to release, and liquid is discharged from or draws.Such water vent is called as and draws.If temperature sensor shows that at this temperature on domestic water entrance rises, this means that so the hot water line is arranged on the domestic water entrance, namely heat exchanger is flow through at the through-flow direction from the domestic water outlet to the domestic water entrance.Therefore, the temperature controlling of the liquid of output or heat exchanger or adjusting are carried out according to the actual temperature that records at the domestic water entrance.Turn off normal operation at this---through-flow direction that normally operates in from the domestic water entrance to domestic water outlet is set---thereby the through type heater moves error running.
Usually in the domestic water outlet temperature sensor is set at this.During through-flow direction that the such temperature sensor in the domestic water outlet export when the hot water line correctly is connected with the cold water pipeline, from from the domestic water entrance to domestic water for detection of the actual temperature the hot water line and be used for control or adjusting thus and be delivered to heat on the liquid by heat exchanger.Further improve faulty identification by the temperature sensor in the domestic water outlet in this operation.It still is information in the domestic water outlet that the providing of the temperature in domestic water entrance and domestic water exit is connected the domestic water entrance about the cold water pipeline more reliablely.If the temperature of domestic water porch surpasses the temperature in domestic water exit, have the miss change of joint so, thereby the through type heater should move in error running.
Preferably on the domestic water entrance and/or in the domestic water outlet, a flow sensor is set.Such flow sensor exists in a lot of traditional through type heaters, wherein, obtains discharge rate by flow sensor, and this discharge rate is used for control and is delivered to heat on the liquid by heat exchanger.Such flow sensor is only reliable on through-flow direction usually at this, whether wherein, can be used for identification cold water pipeline equally according to the directional dependency of the through-flow sensor of the present invention correctly is connected on the domestic water entrance and whether the hot water line correctly is connected to the domestic water outlet.Flow sensor does not provide any signal if though the temperature of domestic water porch improves, namely do not send the signal of discharge, then there is the connection of tangible miss change, thereby the through type heater must move in error running, and wherein the adjusting of the liquid of Pai Chuing is carried out according to the temperature of domestic water porch.
In a kind of preferred expanded configuration, heat exchanger has a secondary loop with pump and thermal source, and they can be controlled by control device.To be brought in the heat exchanger and therefrom by the heat that thermal source produces by secondary loop and pump and be delivered on the liquid, thereby can discharge liquid heatedly.Thermal source can have different configurations at this, for example constitutes as gas burner or oil burner or as electrical heating elements.Can expect that also the secondary loop for example is constructed to the part of central heating system.
Preferred control device has a memory, wherein can store following state:
0: need to check,
1: normal operation,
2: error running,
Wherein, the state according to storage carries out the operation of through type heater.In order to store corresponding state, need a byte at this, this has advantage with respect to the storage in simple binary digit, namely more is not vulnerable to erroneous effects., store in memory at this: need to check in other words before the first start in the initialization first of through type heater.Guarantee thus, check at every turn after reconnecting: whether the hot water line correctly is connected to the domestic water outlet upward and whether the cold water pipeline correctly is connected on the domestic water entrance.If answer is sure, the through type heater is stored in the memory in normal work in service and this state so.Normally in service, can carry out different settings by the user, for example the through type heater moves in economic model or comfort mode.In economic model, in order to save energy, when not having liquid to be drawn, allow heat exchanger to cool off to a great extent.In error running, namely be connected on the domestic water entrance and cold water pipeline when being connected to domestic water outlet and going up as the hot water line, can not in economical operation, move on the contrary, because what should connect in error running reexamines, this closely just may when heat exchanger moves in a temperature range of operation.Other setting possibility by the user also may be limited in error running.
Preferred control device is designed in this wise, make the fluid of when the hot water line is connected on domestic water entrance heat to obtain and display demonstration error running when needed at the domestic water entrance, wherein, especially the temperature of heat exchanger is enhanced or keeps constant, perhaps is conditioned according to the temperature in the domestic water entrance.Even if when the miss change of joint, can realize enough operations of through type heater thus.By corresponding display is set, installation personnel can be found out and error cause removal faster.But except eliminating mistake, do not need to make the through type heater to stop.But can realize restricted operation.
This task requires the method for 6 feature to solve according to the present invention by having claim.
At this, obtain liquid by the through-flow direction of heat exchanger, wherein, realize that according to through-flow direction the actual temperature of liquid is to the adjusting of predetermined rated temperature.The through type heater not only can be the through-flow direction of the outlet from the domestic water entrance to domestic water, namely during correct connection the at hot water line and cold water pipeline but also can to the opposite through-flow direction of domestic water entrance, move exporting from domestic water.At this, can use different adjusting parameters according to through-flow direction.For example, rated temperature can be by predetermined regularly from the domestic water outlet to the through-flow direction of domestic water entrance, and rated temperature can change by the user the correct through-flow direction of the outlet from the domestic water entrance to domestic water, for example by selecting economic model.
Advantageously, through-flow direction is obtained to the temperature survey in domestic water exit and/or in conjunction with the flow sensor in domestic water entrance or the domestic water outlet by the temperature survey combination when needed to the domestic water porch.It is that the hot water line is connected to the sign on the domestic water entrance that the temperature of domestic water porch improves, and namely through-flow direction leads to the domestic water entrance from the domestic water outlet.Yet faulty identification can be more reliable in the following manner, namely also detects the temperature in domestic water exit.If the temperature of domestic water porch thinks the temperature in cuckoo domestic water exit and improve when discharging liquid, through-flow from the domestic water outlet to the domestic water entrance so obviously takes place.The flow sensor that depends on direction can be used to obtain through-flow direction equally.Yet for the actual temperature of the liquid of regulating discharge, also need to detect the temperature of domestic water porch.
Preferably measure a temperature T 1 and measure a temperature T 2 in the domestic water outlet at the domestic water entrance, wherein, when temperature T 2 is higher than temperature T 1, temperature T 2 is adjusted to rated temperature, and when temperature T 1 is higher than temperature T 2, temperature T 1 is adjusted to rated temperature.Namely not only detect the temperature of domestic water porch but also the temperature in detection domestic water exit.The basis of regulating is the detected temperatures of being heat in this poem, and it provides the situation about the through-flow direction of heat exchanger inside reliably.If the temperature T 2 in domestic water exit is greater than the temperature T 1 of domestic water porch, have normal operation so, and if the temperature T 1 of domestic water porch is higher than the temperature T 2 in domestic water exit, have error running so.On existing normal operation or error running to decide, control device can move in different patterns in other words by different programs.
At this particularly preferably, one of following three states of storage in a memory:
0: need to check,
1: normal operation,
2: error running,
Wherein, memory is set to " 0 " when the initialization of through type heater and/or when long downtime, wherein, especially repeats the inspection to through-flow direction in error running.In delivery state, namely before the initialization first or first start of through type heater, storage needs to check in memory.Therefore when first start, check, see whether hot water line and cold water pipeline correctly are connected.Reheat heat exchanger and detect the temperature of domestic water porch for this reason.Additionally detect when needed the domestic water exit temperature and with the temperature of domestic water porch relatively.Also can expect detect whether carry out the liquid discharge by flow sensor.If the temperature of domestic water porch is higher than the temperature in domestic water exit now, then in memory, to store, the through type heater is worked in error running.If rising, the temperature in domestic water exit surpasses the temperature of domestic water porch, storage so, and the through type heater is in normal work in service.In error running, only be limited reliably in this user's setting, wherein, for example this operates in the economic model and can not realize, thereby does not carry out the unnecessary cooling of heat exchanger.Stipulate in error running at this, carry out the inspection of upgrading periodically of through-flow direction.
Preferably in this temperature that in error running, keeps heat exchanger between temperature upper limit and lowest temperature.This can for example be undertaken by fuzzy the adjusting.
Preferably in error running, use ratio at normal high rated value in service.Guarantee thus, even if in cold water pipeline and hot water line's incorrect the connection, also the liquid of enough heat is discharged to the hot water line from heat exchanger.Improve faulty identification at the same time by the rated value that improves, because the raising of rated value causes the temperature of the increase when discharging liquid to improve.
Description of drawings
The present invention is described in detail by reference to the accompanying drawings according to a preferred embodiment below.Shown in it:
Fig. 1 illustrates the schematic diagram of through type heater; With
Fig. 2 illustrates possible method flow.
The specific embodiment
Through type heater 1 with heat exchanger 2 shown in Figure 1, wherein, heat exchanger 2 has a domestic water entrance 21 and a domestic water outlet 22.The heat energy that produces in thermal source 52 flows to heat exchanger 2 by a secondary loop 5.At this, heat energy from thermal source 52 to heat exchanger 2 transmission undertaken by liquid, especially water, it drives by pump 51.
When correct the installation, cold water pipeline 31 is arranged on the domestic water entrance 21 and a hot water line 32 is arranged in the domestic water outlet 22.Through-flow direction by heat exchanger 2 32 carries out from cold water pipeline 31 towards the hot water line then.At this, in heat exchanger 2, realize heat energy to the transmission of liquid, i.e. the heating of liquid, liquid is discharged hot water line 32 with being heated.Hypothesis below: make water as liquid, wherein, yet also can expect using other liquid.
Can be delivered to the heat energy of water by 4 adjustings of a control device by heat exchanger 2.Usually detect discharge rate at this by a flow sensor 8, wherein, control device determines must transmit how many heat in heat exchanger 2 according to discharge rate.The heat energy of bringing into by secondary loop 5 correspondingly is transferred then.When cooling water pipeline correctly is connected with the hot water line, namely export from the domestic water entrance to domestic water when carrying out when through-flow direction, a kind of such control device is worked satisfactorily.Can realize that by the adjusting of temperature sensor 7 adjusting of rated temperature, this temperature sensor are arranged in the domestic water outlet 22 at this.
On opposite through-flow direction, namely be connected in the domestic water outlet 22 and hot water line 32 when being connected on the domestic water entrance 21 when cold water pipeline 31 in wrong way, yet the flow sensor 8 no longer temperature sensor 7 in output signal and the domestic water outlet 22 only shows stationary temperature, the i.e. temperature of Shu Ru cold water all the time.Correspondingly at this moment can not realize the controlled discharge of hot water.
Stipulate now according to the present invention, at domestic water entrance 21 temperature sensor 6 is set.Such temperature sensor 6 namely detects pre-warmed water at domestic water entrance 21 in correct connection, namely during outlet 22 through-flow direction, have other monitoring function from domestic water entrance 21 to domestic water.For example in order to determine the water preheat of solar energy.In case the water temperature at domestic water entrance 21 places exports at domestic water more than the water temperature at 2 places, so straight flow heater 1 in other words its thermal source 52 be not activated.In addition, temperature sensor 6 can be used for by in advance adjusting, namely under the situation of considering the water inlet temperature, optimize the water temperature that domestic water exports 22 places.Yet it can realize through-flow direction reliable determines and the adjusting of the rated temperature of the liquid of output, even if when the hot water line is connected on the domestic water entrance 21, when namely straight flow heater 1 is flow through mistakenly.
When correct the connection, namely be connected on the domestic water entrance 21 and there is a kind of normal operation when being connected in the domestic water outlet 22 in hot water line 32 at cold water pipeline 31.When heat exchanger 2 moves in the opposite direction, namely be connected in the domestic water outlet 22 and hot water line 32 when being connected on the domestic water entrance 21 when cold water pipeline 31, there is a kind of error running.Can show in display 9 at this whether have error running, thereby for example by being identified immediately by installation personnel, whether hot water line 32 and cold water pipeline 31 correctly are connected on the heat exchanger 2.
A kind of possible flow process according to method of the present invention schematically is shown in Fig. 2.After installing first, namely when the load operation first of through type heater 1 or after long-time interrupt run, heat exchanger 2 at first is heated.When discharging hot water, detect the temperature at domestic water entrance 21 places.Thermal source 52 can provide more heat now when needed, wherein, at this moment detects the temperature at domestic water entrance 21 places continuously.The temperature at domestic water entrance 21 places compares with the temperature that detects after a while before thermal source 52 startings.When the temperature raising occurring, through-flow direction is 21 realizations from domestic water outlet 22 towards the domestic water entrance, namely have error running.Therefore go out to discharge hot water and the actual temperature at domestic water entrance 21 places is regulated at domestic water entrance 21.Although thermal source 52 provides heat energy to heat exchanger 2, if but the temperature at domestic water entrance 21 places descends, cold water pipeline 31 correctly is connected with hot water line 32 and realizes normally moving so, wherein hot water is discharged from domestic water outlet 22, is adjusted to rated temperature thereby domestic water exports the temperature at 22 places.
The heating of through type heater 1 when load running first irrespectively carried out at this and following situation, which pattern that is through type heater 1 is set, namely for example whether selected economic model, the heating of heat exchanger 2 is only carried out when needed in economic model.
If except the temperature detection at domestic water entrance 21 places, also carry out the temperature detection in the domestic water outlet 22 now, can determine through-flow direction more simply by the comparison of two temperature so.If domestic water exports the temperature at 22 places above the temperature at domestic water entrance 21 places during discharging liquid, the through type heater is positioned at normally in service so.If when the temperature at domestic water entrance 21 places exported the temperature rising at 22 places with respect to domestic water on the contrary, then through type heater 1 was arranged in error running.Faulty identification can additionally be improved by a flow sensor is set at this.
If do not cool off on domestic water entrance 21 when discharging liquid, namely occurrence temperature does not descend, and error running can be assumed to be so.
