The inflow temperature of gas heater 10 is detected by the hot inflow temperature sensor of combustion.
Inflow temperature such as gas heater 10 subtracts predetermined lowest temperature more than or equal to design temperature and appreciated, then controls combustion gas
Water heater 10 is closed.Inflow temperature such as gas heater 10 be less than the design temperature subtract as described in predetermined lowest temperature appreciation, then
Control gas heater 10 starts.
Wherein, the design temperature is the temperature of user's setting, and it is gas heater 10 that the predetermined lowest temperature, which is appreciated,
Lowest temperature rise, by adding the predetermined lowest temperature in the relatively inflow temperature of gas heater 10 and the design temperature
Appreciate, can fully improve the utilization rate of the energy.
The water temperature of electric heater 40 is detected by the electric heating temperature sensor.
Water temperature such as electric heater 40 is less than or equal to the design temperature, then control electric heater 40 starts and by electric heating
The water temperature heating of hydrophone 40 to the design temperature adds predetermined reserved value, and improves the target temperature of gas heater 10 to improve
The power of gas heater 10.Water temperature such as electric heater 40 is more than the design temperature, then control electric heater 40 is closed, and
The target temperature of gas heater 10 is reduced to reduce the power of gas heater 10.Pass through the water temperature in relatively electric heater 40
The predetermined reserved value is added during with the design temperature, the frequent starting of electric heater 40 can be prevented.
Pass through the water temperature of the terminal hot water temperature sensor detection terminal hot water water end (W.E.) 63.
Terminal hot water with the water temperature of water end (W.E.) 63 is less than the design temperature, then the aperture of reduction Cold water tap 61 and/or
Increase the aperture of hot-water valve 62.The design temperature as described in being more than with the water temperature of water end (W.E.) 63 terminal hot water, then increase Cold water tap
61 aperture and/or the aperture for reducing hot-water valve 62.The design temperature as described in being equal to the water temperature of water end (W.E.) 63 terminal hot water, then
Maintain the aperture of Cold water tap 61 and hot-water valve 62 constant.

The water temperature of 10 inflow temperature, the water temperature of electric heater 40 and terminal hot water water end (W.E.) 63, control gas heater 10 and electric heating
The keying of hydrophone 40 and the aperture of power and Cold water tap 61 and hot-water valve 62, can be in hot water effluent's terminal adjusting water outlet
Temperature, so as to realize that constant temperature exports.
Specifically, it is 2 DEG C that the predetermined lowest temperature, which is appreciated, and the predetermined reserved value is 2 DEG C.
In some specific embodiments of the present invention, as shown in figure 3, combustion electricity complementary thermal water system according to embodiments of the present invention
The temprature control method of system 1 also includes：
As after the scheduled time terminal hot water with the water temperature of water end (W.E.) 63 still less than the design temperature, then control gas and hot water
Device 10 and electric heater 40 start, and the lifting of the target temperature of gas heater 10 and electric heater 40 is made a reservation for into upper tone pitch.Such as
Terminal hot water then controls electric heater 40 to close with the water temperature of water end (W.E.) 63 still above the design temperature after the scheduled time
Close, and the target temperature of gas heater 10 is reduced into predetermined lower tone pitch.
Thus, when mixed water adjusts the regulating power of source device 60 can not adjust actual leaving water temperature to design temperature, lead to
Control gas heater 10 and electric heater 40 are crossed, to ensure that final hot water outlet temperature can reach design temperature.
Specifically, the scheduled time is 5 seconds, and the predetermined upper tone pitch is 2 DEG C, and the predetermined lower tone pitch is 2 DEG C.
In some specific examples of the present invention, as shown in figure 3, combustion electricity complementary hot-water system according to embodiments of the present invention
1 temprature control method also includes：
Terminal hot water controls electric hot water with the water temperature of water end (W.E.) 63 still above the design temperature after the scheduled time as described in

Alternatively, as shown in figure 3, when the inflow temperature of gas heater 10 is more than the design temperature, or and cold valves
When the connected cold water of door 61 is more than the design temperature with the water temperature of water end (W.E.) 31, gas heater 10 and electric heater 40 is controlled to close
Close and by the alarm equipment alarm, so as to prevent user to be burned.
Below with reference to the accompanying drawings the flow control methods of the description electric complementary hot-water system 1 of combustion according to embodiments of the present invention.
As shown in figure 4, the flow control methods of the electric complementary hot-water system 1 of combustion according to embodiments of the present invention include：
In the case where ensureing constant-temperature effluent (final outflow water range of temperature is within 2 DEG C), pass through terminal heat
The flow of water flow sensor detection terminal hot water water end (W.E.) 63.
When terminal hot water with the flow value added of water end (W.E.) 63 in predetermined amount of flow constant interval when, then control gas heater
10 target temperature reduces the predetermined hot temperature adjustment value of combustion, and the target temperature of control electric heater 40 reduces predetermined electric heating temperature and adjusted

Hot temperature adjustment value, increase the aperture of Cold water tap 61 and the aperture of hot-water valve 62.
The flow control methods of the electric complementary hot-water system 1 of combustion according to embodiments of the present invention, pass through temperature and cold and hot pipeline
Pressure regulation terminal water flow, so as to be further ensured that constant current output in the case where ensureing constant temperature output, and need not set
Flow-rate adjustment motor-driven valve is put, precision is higher, and cost is lower.
Specifically, the predetermined amount of flow constant interval is 1-2L/MIN, and the predetermined hot temperature adjustment value of combustion is 1 DEG C,
The predetermined electric heating temperature adjustment value is 1 DEG C.
In other words, when terminal hot water increases below 1L/MIN with the flow of water end (W.E.) 63, ignore, when terminal hot water is used
During the flow increase 1-2L/MIN of water end (W.E.) 63, calculated by 2L/MIN, the flow of terminal hot water water end (W.E.) 63 often increases 2L/MIN, then fires
The target temperature of gas water heater 10 and electric heater 40 just reduces by 1 DEG C, and reduces the aperture of Cold water tap 61 and increase hot water valve
The aperture of door 62.
When terminal hot water reduces below 1L/MIN with the flow of water end (W.E.) 63, ignore, when terminal hot water water end (W.E.) 63
Flow reduce 1-2L/MIN when, calculated by 2L/MIN, the flow of terminal hot water water end (W.E.) 63 often reduces 2L/MIN, then gas and hot water
The target temperature of device 10 and electric heater 40 just lifts 1 DEG C, and increases the aperture of Cold water tap 61 and the aperture of hot-water valve 62.
In some specific embodiments of the present invention, as shown in figure 4, combustion electricity complementary thermal water system according to embodiments of the present invention
The flow control methods of system 1 also include：
As when terminal hot water is not equal to setting flow all the time with the flow of water end (W.E.) 63 in the scheduled time, then passed through the alarm
Device is alarmed and recommends constant flow rate setting value with the flow of water end (W.E.) 63 according to terminal hot water in the scheduled time.
Wherein, the output flow for setting flow and being set as user, and the recommendation constant flow rate setting value is system
Recommend the output flow of setting to user according to reality output flow.
Alternatively, the scheduled time is 30 seconds.
