The invention discloses a power control method for a fuel gas heating water heater. The power control method comprises the steps that the maximum power of hot water and the maximum power of heating are set; and the fuel gas heating water heater is controlled according to the working condition, the set maximum power of the hot water and the set maximum power of heating. According to the power control method for the fuel gas heating water heater, on the basis that existing hardware equipment of the fuel gas heating water heater is not changed, the maximum power of the hot water and the maximum power of heating are separately set, hot water supplying and heating supplying are independently controlled, and the segmented burning technology is combined, so that the control power during heating working is low, and the work performance of the fuel gas heating water heater is ensured; the control power is high when the hot water is supplied, and a working curve is extended so that the fuel gas heating water heater can supply a larger amount of water flow and the higher water temperature; the equipment performance of the fuel gas heating water heater can be fully utilized, the hardware configuration and energy consumption of the fuel gas heating water heater are reduced on the basis of meeting user heating and hot water supplying requirements, and the effects of energy saving and emission reduction are achieved.
Description
Technical field
Present invention relates particularly to the Poewr control method of a kind of gas-heating water heater.
Background technology
Along with development and the raising of people's living standard of economic technology, family heating has had become as one of selection of increasing urbanite.Gas-heating water heater can supply the advantage of domestic hot water and heating hot water with it simultaneously, has had become as one of preferred unit of family heating.
Existing gas-heating water heater is provided with a power bracket when dispatching from the factory, no matter heating state or hot water conditions, its output is all in the range of this.But during gas-heating water heater type selecting, majority of case is all that hot water power is more than heating power.If being as the criterion with heating power, it is impossible to meet the comfortable hot water demand of big flow, in the case of basis water temperature is relatively low the most in the winter time.So for guaranteeing to meet hot water demand, it is forced to hot water power during type selecting and is as the criterion and determines peak power output.But in the case, when especially heating power is much smaller compared with hot water power, under heating duty, gas-heating water heater can frequent start-stop.
The use frequency of the gas heater low and continuous use time is short, and the maximum combustion intensity of its single fire row is typically at more than 3kW；And gas-heating water heater uses frequency high and uses the time long continuously, for ensureing its useful life longevity, the maximum combustion intensity relatively gas heater of single fire row decreases, generally 2kW.And with maximum heat water-horse power as reference during type selecting, and hot water demand uses the time shorter, therefore water heater works long hours in small-power state, and the performance causing the parts such as gas-heating water heater burner, heat exchanger is superfluous.Popularizing especially as energy saving building, heating power is reducing；And user pursues, and flow is big, comfort level is high hot water is experienced, hot water power is strengthening, and the powerful situation of heating small-power, hot water is increasing, and also causes gas-heating water heater performance surplus situation in aggravation.
Summary of the invention
It is an object of the invention to provide a kind of equipment performance that can make full use of gas-heating water heater, the Poewr control method of gas-heating water heater energy-saving and cost-reducing on the basis of meeting user heating and hot water supply.
The Poewr control method of this gas-heating water heater that the present invention provides, comprises the steps:
S1., two power, respectively P are setmax1And Pmax2, with Pmax1For hot water peak power, with Pmax2For heating peak power, and Pmin<
Pmax2< Pmax1<Pmax；Wherein PminFor gas heating stove minimum power, PmaxPower can be provided for gas heating stove maximum；
S2. gas-heating water heater is according to operating mode, the hot water peak power arranged according to step S1 and heating peak power, is controlled gas-heating water heater:
With [Pmin, Pmax2] it is between power control zone, the heating operation to gas-heating water heater is controlled；
With [Pmin, Pmax1] it is between power control zone, the hot water supply operation to gas-heating water heater is controlled.
Hot water peak power described in step S1, the relation of heating peak power are 1 ＜ Pmax1/Pmax2＜ 1.5.
The hot water to gas-heating water heater described in step S2 is supplied operation and is controlled, and is controlled the hot water supply operation of gas-heating water heater for combining sectional combustion technology.
Described sectional combustion technology is two-part sectional combustion technology.
The ratio of the segmentation/standard-sized sheet of described two-part sectional combustion technology is 0.5.
Described in step S1, hot water peak power and heating peak power are set, for being configured on the control panel of gas-heating water heater or operation display.
The Poewr control method of this gas-heating water heater that the present invention provides, on the basis of the hardware device not changing existing gas-heating water heater, by being provided separately hot water peak power and heating peak power, and independently hot water supply and heating supply are controlled, and combine sectional combustion technology, when gas-heating water heater heating works, control power relatively low, can preferably ensure the service behaviour of gas-heating water heater, and when gas-heating water heater hot-water supply, greatly extend gas-heating water heater at hot water for seasonable service behaviour, make gas-heating water heater can provide bigger discharge and higher water temperature；The present invention can make full use of the equipment performance of gas-heating water heater, reduces hardware configuration and the energy consumption of gas-heating water heater, energy-saving and emission-reduction on the basis of meeting user heating and hot water supply.
Accompanying drawing explanation
Fig. 1 is the inventive method flow chart.
Fig. 2 is the water yield-water temperature curve figure of the present invention.
Detailed description of the invention
It is illustrated in figure 1 the method flow diagram of the present invention: the Poewr control method of this gas-heating water heater that the present invention provides, comprises the steps:
S1. two power, respectively P are set on the control panel or operation display of gas-heating water heatermax1And Pmax2, with Pmax1For hot water peak power, with Pmax2For heating peak power, and Pmin<
Pmax2< Pmax1<Pmax；Wherein PminFor gas heating stove minimum power, PmaxPower can be provided for gas heating stove maximum；1 ＜ P can be chosenmax1/Pmax2＜ 1.5；
S2. gas-heating water heater is according to operating mode, the hot water peak power arranged according to step S1 and heating peak power, is controlled gas-heating water heater:
With [Pmin, Pmax2] it is between power control zone, the heating operation to gas-heating water heater is controlled；
With [Pmin, Pmax1] it is between power control zone, in conjunction with two-part sectional combustion technology, the ratio of the segmentation/standard-sized sheet set is as 0.5, and the hot water supply operation to gas-heating water heater is controlled.
It is illustrated in figure 2 the water yield-water temperature curve figure of the present invention: T in figure0For hot water minimum temperature；T1For hot water maximum temperature；L1Flow is started for water heater minimum；L2The maximum stream flow allowed for water heater；It can be seen that the gas-heating water heater of non-sectional combustion can provide the temperature rise of hot water and range of flow to be region II, after using sectional combustion technology, adding region I, solution basis water temperature in summer is higher, and the problem that when discharge is less, hot water temperature is the highest；After using the control method of the present invention, add region III, solve winter basis water temperature relatively low, it is impossible to the problem that the comfortable hot water of big flow is provided, it is ensured that have that flow is suitable, the hot water of temperature pleasant a summer in winter.
