In the diagram, composition graphs 1 describes.
First, in the opening and closing of controller (3) Controlling solenoid valve, cold water is in water-heater water tank, then utilizes solar energy heating.
Then, then according to Fig. 4, system is divided into two works:
Hot water temperature T in solar water heater (1) is measured by sensor (2).
If 1 this water temperature T is higher than design temperature T in controller
0time (45 DEG C), auxiliary heater (9) does not work:
(1) water temperature T of getting off from solar water heater (1) measured by temperature sensor (14)
1, and by controller (3) and design temperature T
0compare.If T
1lower than T
0then three-way magnetic valve (15) changes flow direction, make current direction storage tank (13), utilize cold water pipes caliber to reduce produced suction effect, the water in storage tank (13) is back in cold water pipe by one way stop peturn valve (12) and mixes with it.If T
1higher than T
0, then temperature control valve (TCV) (6) is directly flowed to.
(2) when hot water and cold water are after temperature control valve (TCV) (6) fully mixing, by temperature sensor (5), T is detected as to delivery port water flow temperature
2.If T
2higher than user's design temperature T
3,then Driving Stepping Motor increases cold water pipe valve opening and reduces hot-water line valve opening.If T
2lower than T
3, then reduce cold valves aperture and increase hot-water line valve opening, realize the adjustment of water flow size by adjust flux control valve 7, and the adjustment of leaving water temperature and flow is independent of each other simultaneously.
If 2 solar water heaters (1) interior water temperature T is lower than design temperature T
0time, auxiliary heater (9) works.
(1) water temperature T of getting off from solar water heater (1) measured by temperature sensor (14)
1, and compared by controller (3) and coolant-temperature gage T in solar energy.If T
1lower than T, then three-way magnetic valve (15) changes flow direction storage tank (13) and is back in cold water pipe.If T
1higher than T, then three-way magnetic valve (15) is changed the direction of a stream of water, and after making it flow to auxiliary heater (9) heating, then flows to temperature control valve (TCV) (6).
(2) when hot water and cold water are after temperature control valve (TCV) (6) fully mixing, by temperature sensor (5), T is detected as to delivery port water flow temperature
2.If T
2higher than user's design temperature T
3, then Driving Stepping Motor increases cold water pipe valve opening and reduces hot-water line valve opening.If T
2lower than T
3, then reduce cold valves aperture and increase hot-water line valve opening, realize the adjustment of water flow size simultaneously by adjust flux control valve 7.
In above two flow processs, the cold water in hot-water line is finally back in cold water pipe through storage tank (13) and one way stop peturn valve (12), solves because " hot standby " causes water resource waste problem; Auxiliary heater (9) heating design again, makes it heat the hot water that solar energy flows down again, and comparatively electric energy saved by other auxiliary heaters; Temperature compensated flow designs, and solves the problem that the low water flow caused of setting height(from bottom) is little, and improves user and to take a shower comfort level; Controller (3) control step motor actuation temperature control valve (6) and flow control valve (7), realize the adjustment of leaving water temperature and flow, and separate, optimizes existing thermostatic control system.
