Abstract
The invention discloses a kind of hot water Supply Method applied to solar water heater, comprise the following steps：The hot water that solar water heater is heated to certain temperature is stored in boiler A, and hot water is maintained in the range of design temperature in boiler；B, the hot water amount in current boiler is detected；C, according to the estimated water consumption in historical water usage estimated following certain time；D, the hot water amount of such as current boiler is not less than estimated water consumption, step A is then performed, the hot water amount of such as current boiler is less than estimated water consumption, then starts electric heater unit, increase the hot water amount in boiler, until the hot water amount in boiler is not less than estimated water consumption.The present invention predicts the estimated water consumption in following certain time according to historical water usage, and water consumption storage hot water, ensure that hot water is in liberal supply on the estimation, without interim heat hot water, save the stand-by period, the supply of hot water is more intelligent, and use is more convenient.
Description
Technical field
The present invention relates to hot water to supply field, more particularly to a kind of hot water Supply Method applied to solar water heater.
Background technology
At present, for environmental protection and energy saving, many families are supplied water using solar water heater, especially in rural area, using more
Generally.But at present solar water heater using when there are problems with：When solar irradiation is insufficient, it is necessary to which pre-cooling is electric
Heating devices heat hot water, otherwise uses without hot water, and is required to be manually operated every time, and use is extremely inconvenient, and cannot basis
The hot water amount for needing selection to heat, causes the waste of the energy.
The content of the invention
For overcome the deficiencies in the prior art and there are the problem of, the present invention provide a kind of heat applied to solar water heater
Water supplying method, it is ensured that the storage of hot water, can use hot water immediately.
The present invention is achieved by the following technical solutions：
A kind of hot water Supply Method applied to solar water heater, comprises the following steps：A, solar water heater is heated to
The hot water of certain temperature is stored in boiler, and when hot water temperature is less than setting value in boiler, hot water is pumped into boiler
Circulating-heating is carried out in solar water heater so that hot water is maintained in the range of design temperature in boiler；B, the current heat of detection
Hot water amount in water tank；C, according to the estimated water consumption in historical water usage estimated following certain time；D, such as current hot water
The hot water amount of case then performs step A, such as the hot water amount of current boiler not less than the estimated water consumption in following certain time
Less than the estimated water consumption in following certain time, then start electric heater unit, increase the hot water amount in boiler, until heat
Hot water amount in water tank is not less than the estimated water consumption in following certain time.
Historical water usage refers in the last week the average value of water consumption in section while daily in the step C.
When the following certain time is set as that 0.5-2 is small.
The desired temperature of hot water is 45 ° -60 ° in the boiler.
Hot water temperature is detected by temperature sensor in the boiler, and temperature sensor is equipped with two, respectively positioned at heat
The both ends of water tank.
Beneficial effects of the present invention：The estimated water consumption in following certain time, root are predicted according to historical water usage
It is expected that water consumption stores hot water, it ensure that hot water is in liberal supply, without interim heat hot water, saved the stand-by period, hot water
Supply it is more intelligent, use is more convenient.
Embodiment
For the ease of the understanding of those skilled in the art, present invention work is further retouched in detail below in conjunction with specific embodiment
State.
A kind of hot water Supply Method applied to solar water heater, comprises the following steps：A, solar water heater is added
The hot water of heat to certain temperature is stored in boiler, when hot water temperature is less than setting value in boiler, hot water in boiler
It is pumped into solar water heater and carries out circulating-heating so that hot water is maintained in the range of design temperature in boiler, this can be protected
Hot water temperature in card boiler can directly use all the time, and the desired temperature of hot water is 45 ° -60 ° in boiler；B, detect
Hot water amount in current boiler；C, used according to the estimated water consumption in historical water usage estimated following certain time, history
Water refers in the last week the average value of water consumption in section while daily, this may be such that pre- in estimated following certain time
Meter water consumption is with actual next water consumption more closely, when next certain time is set as that 0.5-2 is small；D, such as current hot water
The hot water amount of case then performs step A, such as the hot water amount of current boiler not less than the estimated water consumption in following certain time
Less than the estimated water consumption in following certain time, then start electric heater unit, increase the hot water amount in boiler, until heat
Hot water amount in water tank is not less than the estimated water consumption in following certain time.
Further, hot water temperature is detected by temperature sensor in boiler, and temperature sensor is equipped with two, respectively position
In the both ends of boiler.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on, should all be included in the protection scope of the present invention.
