Technical field
The invention belongs to heating, hot water supply field, specifically relate to the supply control method for heat of the auxiliary heating of a kind of solar heating and water heater.
Background technology
Solar thermal collector is converted into heat energy to solar energy luminous energy, sunny slope by heat collector is subjected to solar radiation and the temperature height, the opaco temperature is low, and water just produces temperature difference reaction in the pipe, the principle of utilizing hot water come-up cold water to sink, make the water generates microcirculation and reach required hot water, use to satisfy the hot water of people in life, production.Solar energy heat distribution system by heat collector, heat storage water tank, heat transmission equipment, water heater, warmer and related accessories form, belong to sole user's type heating system.At present, solar energy heat distribution system trends towards the centralized control model development of multi-user's type, therefore, the supply control method for heat of unique user can not adapt to current demand, particularly when overcast and rainy, because the solar-heating deficiency, the water heater heating schedule plays an important role, design is unreasonable if water heater adds thermal control program, then can influence the actual use experience of user.
Summary of the invention
In order to solve the problem that prior art exists, the invention provides a kind of solar energy and gas water-heating furnace and organically combine and reasonable, the centralized supply control method for heat of workflow, to satisfy the big used in amounts summation of user comfort.
In order to realize above purpose, technical scheme of the present invention is as follows: solar heating water heater centralized Control method, comprise the summer mode that is used for the domestic hot-water, the water heater controller is start earlier, and if any the auxiliary heating signal of bathroom, Centralized Controller sends signal instruction, three-way solenoid valve is in connected state, carry out ignition procedure, warm water is heated to 70～90 degree, up to removing the bathroom signal.
Further, as do not have bathroom and assist heating signal, then enter the winter mode that is used for heating for residential area, the water heater controller is start earlier, Centralized Controller sends signal instruction, three-way solenoid valve is in connected state, if heating temperature T4 is higher than user's design temperature Tc value, the heating water pump operation, if heating temperature T4 is lower than the difference of user's design temperature Tc when spending less than 10～20, then carry out ignition procedure, when the difference that is higher than user's design temperature Tc to heating temperature T4 to be heated was spent greater than 5～10, the heating water pump cut out.
The scope of described user's design temperature Tc is 30～60 degree.
Has hydraulic pressure open failure alarm signal before the described three-way solenoid valve connected state.
The execution of described water heater water pump closing motion is by closing the gas signal controlling.
Described water heater water pump cut out after delaying time at least 2 minutes or 3 minutes.
The signal that described water heater starting mode of pump was received according to the water heater controller after 20 seconds makes to judge back selection heating program or auxiliary heating schedule.
The auxiliary heating signal of bathroom under the described summer mode remove or winter mode under have the purging signal that bathroom standby signal or water heater blower fan have and be disengaged, then bathroom is handled holding state.
In the winter time under the pattern, by the break-make of constant indoor temperature signal controlling hydraulic signal.
In the auxiliary heating process of bathroom, if arriving 80 degree backs, warm water continues to surpass 50 minutes or 55 minutes or 60 minutes, stop the auxiliary heating of bathroom automatically.
Compared with prior art, supply control method for heat of the present invention is applicable to the centralized Control of multi-user's type, i.e. each user's heat supply is controlled by the Centralized Controller centralized Control, therefore, on heating function, the heating of solar energy assisted gas heating hot water stove; On domestic hot-water's function, gas-heating water heater assisted solar system provides the domestic hot-water, and by unified intelligent controller both is connected together, and has reached and has had complementary functions.

Fig. 2 is an application schematic diagram of the present invention.
Below, with accompanying drawing the present invention is described in further detail in conjunction with specific embodiments.
The specific embodiment
As shown in Figure 1, the present invention is a kind of supply control method for heat in conjunction with solar energy and water heater, its control method is as follows: comprise the summer mode that is used for the domestic hot-water, the water heater controller is start earlier, and if any the auxiliary heating signal of bathroom, Centralized Controller sends signal instruction, three-way solenoid valve is in connected state, carry out ignition procedure, warm water is heated to 80 degree, up to removing the bathroom signal; As do not have bathroom and assist heating signal, then enter the winter mode that is used for heating for residential area, the water heater controller is start earlier, Centralized Controller sends signal instruction, three-way solenoid valve is in connected state, the signal that the water heater starting mode of pump was received according to the water heater controller after 20 seconds makes to judge back selection heating program or auxiliary heating schedule, if heating temperature T4 is higher than user's design temperature Tc value, the heating water pump operation, if heating temperature T4 is lower than the difference of user's design temperature Tc when spending less than 15, then carry out ignition procedure, when the difference that is higher than user's design temperature Tc to heating temperature T4 to be heated was spent greater than 7, the heating water pump cut out.
The scope of user's design temperature Tc is 30～60 degree, is set at 60 degree such as user's design temperature Tc.Have hydraulic pressure open failure alarm signal before the three-way solenoid valve connected state,, then report to the police if hydraulic pressure switch disconnects.The execution of water heater water pump closing motion is by closing the gas signal controlling.The time-delay of water heater water pump was just closed after 3 minutes, and late release can utilize the waste heat of internal system more.
The auxiliary heating signal of bathroom under the summer mode remove or winter mode under have the purging signal that bathroom standby signal or water heater blower fan have and be disengaged, then bathroom is handled holding state.In the winter time under the pattern, by the break-make of constant indoor temperature signal controlling hydraulic signal.
In the auxiliary heating process of bathroom, if arriving 80 degree backs, hot water continues to surpass 60 minutes, stop the auxiliary heating of bathroom automatically.The step of " 60 minutes " avoids using hot water of a specified duration excessively, just avoids the inside, bathroom flue gas too much to cause people's anoxic shock of bathing simultaneously.
