Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings the control method of the water system 1 according to the embodiment of the present invention is described.
As shown in Figure 1, comprise gas heater 100 and multiple storage tank 400 with electric heater (not shown) according to the water system 1 of the embodiment of the present invention, the water inlet of multiple storage tank 400 is connected with the delivery port of gas heater 100 respectively.
As shown in Figure 2, comprise according to the control method of the water system 1 of the embodiment of the present invention:
The elementary hot water outlet temperature of setting water system 1 and whole level hot water outlet temperature.Wherein, the target temperature that described whole level hot water outlet temperature sets for user, described elementary hot water outlet temperature is the heating-up temperature of gas heater 100.The magnitude relationship of described elementary hot water outlet temperature and described whole level hot water outlet temperature can be determined according to actual conditions.Such as, the pipeline between gas heater 100 and storage tank 400 is longer, and thermal loss is comparatively large therebetween, then described elementary hot water outlet temperature can be more than or equal to described whole level hot water outlet temperature.Pipeline between gas heater 100 and storage tank 400 is shorter, and thermal loss is less therebetween, then described elementary hot water outlet temperature can be less than or equal to described whole level hot water outlet temperature.
With under water state, detect the water temperature in gas heater 100, and judge whether the water temperature in gas heater 100 is less than described elementary hot water outlet temperature.
If the water temperature in gas heater 100 is less than described elementary hot water outlet temperature, then controls gas heater 100 and start.If the water temperature in gas heater 100 is more than or equal to described elementary hot water outlet temperature, then controls gas heater 100 and stop.
Detect the water temperature in the storage tank 400 corresponding with using water spot (holding with the hot water effluent of water).And judge whether the water temperature in this storage tank 400 is less than described whole level hot water outlet temperature.
If the water temperature in this storage tank 400 is less than described whole level hot water outlet temperature, then controls the described electric heater corresponding with water spot and start.If the water temperature in this storage tank 400 is more than or equal to described whole level hot water outlet temperature, then controls the described electric heater corresponding with water spot and stop.
According to the control method of the water system 1 of the embodiment of the present invention, by detecting the water temperature in gas heater 100, the start and stop of gas heater 100 can be controlled according to the water temperature in gas heater 100, the water temperature in gas heater 100 is made to be heated to described elementary hot water outlet temperature, thus first time heating is carried out to cold water, because the efficiency of heating surface of gas heater 100 is higher, significantly can improve hot water effluent's speed of water system 1, realize instant-heating.
And, the hot water flowed out from gas heater 100 and the cold water between gas heater 100 and storage tank 400 in pipeline enter storage tank 400, neutralize with the hot water in storage tank 400, and be electrically heated the heating of device second time, water temperature in the storage tank 400 that further detection is corresponding with using water spot, the start and stop of electric heater in it are controlled according to the water temperature in this storage tank 400, make to be heated to described whole level hot water outlet temperature with by the water temperature in storage tank 400 corresponding to water spot, gas heater 100 and multiple storage tank 400 with electric heater is utilized to realize the complementary constant temperature of buffering, thus ensure hot water effluent's temperature constant, without cold water in pipeline.
In addition, by carrying out temperature detection to the water temperature in multiple storage tank 400, and control the start and stop of the electric heater in multiple storage tank 400, multiple storage tank 400 and gas heater 100 is utilized to carry out hot water supply to multiple water spot respectively, can realize multiplex water spot thus, large discharge supplies water, and the water temperature balance between each water spot does not interfere with each other.
Therefore, have according to the control method of the water system 1 of the embodiment of the present invention and can ensure effluent temperature constancy, improve hot water effluent speed, eliminate pipeline inner cold water, multiple water spot exported and the advantage such as flow is large.
Below with reference to the accompanying drawings the control method of the water system 1 according to the specific embodiment of the invention is described.
Described elementary hot water outlet temperature can equal described whole level hot water outlet temperature.That is, with under water state, when the water temperature in gas heater 100 is lower than described whole level hot water outlet temperature, gas heater 100 starts until by the water temp. heating in it to described whole level hot water outlet temperature, both can ensure leaving water temperature thus, can energy resource consumption be reduced again.
Described elementary hot water outlet temperature also can be the equipment maximum temperature of gas heater 100.Particularly, with under water state, gas heater 100 starts, and with described whole level hot water outlet temperature to the heating of equipment maximum temperature Variable power, both can ensure leaving water temperature thus, can improve hot water effluent's speed again.
Alternatively, with under water state, show the hot water outlet temperature of each storage tank 400, i.e. the water temperature of each water spot.The so not only convenient control to water system 1, and can realize by water spot water temperature visible.
In concrete examples more of the present invention, the pressure of the output hot water of regulating gas water heater 100, makes the heat outputting water of gas heater 100 enter multiple storage tank 400 with constant pressure respectively, thus uses the water outlet of water spot constant temperature and pressure.
Further, in order to improve the safety and reliability of water system 1, detecting the pressure in each storage tank 400, when the pressure in storage tank 400 is greater than predetermined safe pressure value, pressure release being carried out to the storage tank 400 of superpressure.Wherein, described predetermined safe pressure value can be arranged according to practical application and equipment requirement.
In specific embodiments more of the present invention, soft water and purified treatment are carried out to the cold water entered before gas heater 100.The water quality of cold water water outlet and hot water effluent can be improved on the one hand, the service life of gas heater 100 and multiple storage tank 400 and each pipeline can be improved on the other hand.
Advantageously, control the chilled water flow direction entered before gas heater 100, only allow the chilled water flow entered before gas heater 100 to flow towards gas heater 100.
Control the hot water direction between gas heater 100 and each storage tank 400, only allow the hot water between gas heater 100 and each storage tank 400 to flow to described storage tank 400 from gas heater 100.Like this can the correct flow direction in water route in assure feed water system 1, prevent water route adverse current.
