The operation principle of a kind of solar water heater control device that mutually can switch with other water heater of the present invention is as follows: shown in Figure 3, during use, first can by the water level in the preset setting solar water heater water tank 17 of controller 10 and water temperature (being usually set as 55 degree), by the preset setting return water temperature of controller 10 (being usually set as 35 degree), by controller 10 preset setting hot water effluent temperature (being usually set as 46 degree), controller 10 shows water level and water temperature after receiving the signal that water-temperature water-level sensor 14 brings.
When the water level in water tank 17 is lower than the water level set, can select two kinds of water feeding modes, a kind of water feeding mode is: controller 10 exports control signal and opens water solenoid valve 9, and upper water is just intake through water return pipeline 4 by cold water watering pipeline 3 in water tank 17; When the water level that water-temperature water-level sensor 14 detects in water tank 17 is in a high position, after controller 10 receives the signal that water-temperature water-level sensor 14 brings, export control signal and close and close water solenoid valve 9, just stop intaking in water tank 17.Another kind of water feeding mode is: when the water level in water tank 17 is lower than the water level set, controller 10 exports control signal and opens branch's magnetic valve 18, and upper water is just intake through hot water line 2 by cold water watering pipeline 3 in water tank 17; When the water level that water-temperature water-level sensor 14 detects in water tank 17 is in a high position, after controller 10 receives the signal that water-temperature water-level sensor 14 brings, export control signal close fork magnetic valve 18, just stop intaking in water tank 17.
When sunny, water temperature in water tank 17 is generally not less than the temperature of setting, during use, fetch boiling water leading 12, at once tap 12 is closed after tap 12 there are flowing out, now, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, export control signal startup water pump 6 to work, export control signal simultaneously and open backwater motor-driven valve 8, hot water line 2 and water return pipeline 4 is made to form circulation waterway, the cold water in hot water line 2 is allowed to be circulated back in water tank 17 as early as possible, in the process, when the temperature of return water temperature sensor 5 mensuration is higher than the return water temperature set, controller 10 switches off the pump 6 and backwater motor-driven valve 8, water stops circulation.Now, then tap 12 of fetching boiling water, just normally can use hot water.
When sunlight is inadequate, water temperature in water tank 17 can lower than the temperature of setting, now can select two kinds of occupation modes, one is: during use, fetch boiling water leading 12, at once tap 12 is closed after tap 12 there are flowing out, now, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, export control signal startup water pump 6 to work, export control signal simultaneously and open backwater motor-driven valve 8, close and often open hot water electromagnetic valve 13, open normally closed hot water electromagnetic valve 16, then other water heater 32 is started, the cold water in hot water line 2 is allowed first to be circulated back in water tank 17, when the temperature that return water temperature sensor 5 measures is consistent with the water temperature in water tank 17, controller 10 switches off the pump 6 and backwater motor-driven valve 8, water stops circulation.Now, fetch boiling water leading 12 again, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, output control signal startup water pump 6 works (or enough not needing also can not start water pump 6 during pressurization at pressure), closedown is often opened hot water electromagnetic valve 13, opened normally closed hot water electromagnetic valve 16, cold water becomes hot water after the heating of other water heater 32, just normally can use hot water.Another kind of occupation mode is: when sunlight is inadequate, water temperature in water tank 17 can lower than the temperature of setting, during use, first start electrical heating 19, temperature in heating water tank 17 is to the temperature 55 DEG C of setting, then leading 12 are fetched boiling water, at once tap 12 is closed after tap 12 there are flowing out, now, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, export control signal startup water pump 6 to work, export control signal simultaneously and open backwater motor-driven valve 8, the cold water in hot water line 2 is allowed first to be circulated back in water tank 17, when the temperature that return water temperature sensor 5 measures is higher than the return water temperature set, controller 10 switches off the pump 6 and backwater motor-driven valve 8, water stops circulation.Now, fetch boiling water leading 12 again, water flow signal transducer 7 detects in hot water line 2 to be had water flow and sends signal, after controller 10 receives the signal that water flow signal transducer 7 brings, export control signal startup water pump 6 to work (or enough not needing also can not start water pump 6 during pressurization at pressure), just normally can use hot water.In addition, in the winter of cold, in order to prevent water tank 17 to be damaged by frost, also can start electrical heating 19 when needed, the water in suitable heating water tank 17.
A kind of solar water heater control device that mutually can switch with other water heater of the present invention can control the switching of solar water heater and other water heater automatically, simple, convenient, reliable.
