Water temperature, the temperature of working media in collecting plate 10 of water tank 20 are obtained respectively.When the water temperature of water tank 20 is less than above-mentioned
First preset value, the water of water tank need to heat, when the temperature of working media and the difference of water temperature of water tank are changed when reaching first
During hot threshold value, controller manipulate the first solenoid valve 71 it is electric by open circulation, 72 dead electricity of second solenoid valve keep block circulation, on
The heating pipeline connection stated, working media can circulate in heating tube stream, and controller manipulates circulating pump 30 and electric must be activated, and adds
Being formed in pipe line makes the driving force of working media flow, and working media flows through heat exchanger 21 by way of heat exchange to heat storage
Water in water tank 20, until the temperature of the working media of collecting plate 10 and the difference of water temperature of water tank 20 reach the second heat exchange threshold value
When stop, or stop when the water temperature of water tank 20 reaches the first above-mentioned preset value, controller manipulates 71 dead electricity quilt of the first solenoid valve
Close and block circulation, second solenoid valve 72 to keep dead electricity to be blocked circulation, the heating pipeline is blocked circulation, controller behaviour
Vertical 30 dead electricity of circulating pump is stopped operating, and working media stops flowing.So far, complete once to heat the water in water tank
Process.The first heat exchange threshold value is more than the second heat exchange threshold value, for example, as a kind of optional scheme, wherein the first heat exchange
Threshold value can exchange heat threshold value using value as 10 DEG C, second can be using value as 3 DEG C.That is, when the working media in collecting plate
When the difference of temperature and the water temperature of water tank reaches 10 DEG C, above-mentioned heating pipeline circulation, circulating pump 30 is activated, working media stream
Logical heat exchanger heats the water in all water tanks；When the working media in collecting plate temperature and water tank water temperature difference be less than 3 DEG C
When, circulating pump 30 is stopped, and above-mentioned heating pipeline is blocked circulation, and working media does not circulate to heat water.Using temperature difference control
Mode processed, the run time that on the one hand can efficiently reduce circulating pump 30 save electric energy；Another aspect temperature difference is bigger, heat exchange

Electric-opening formed circulation, the heat dissipation pipeline formed circulation path, controller manipulate circulating pump 30 it is electric be activated,
Under the suction driving of circulating pump 30, working media flows through radiator 40 and air heat-exchange, the temperature of working media along heat dissipation pipeline
It is lowered, forms the relatively low working media of temperature, the relatively low working media of the temperature is back in collecting plate 10 through heat dissipation pipeline,
So circulation, stops when the temperature of the working media in collecting plate reaches three preset values, and controller manipulates second solenoid valve
72 dead electricity are closed blocking circulation, and the heat dissipation pipeline is blocked, and controller manipulates 30 dead electricity stop motion of circulating pump, work
Medium does not flow.So far, the process for once making working media radiate is completed, the temperature of working media is reduced to safe temperature range
It is interior, to avoid working media because high-temperature gasification forms high pressure in collecting plate, cause collecting plate to damage, or even explosion, favorably prolong
The service life of long collecting plate.Any that working media is allowed when 3rd preset value can be regarded as collecting plate normal work
Relatively low temperature value, in order to reduce the number of starts of circulating pump 30, to save electric energy, the 3rd preset value can value be slightly above the
The a certain value of one preset value, if for example, the first preset value value be 65 DEG C, the 3rd preset value can value be 75 DEG C.Thus, when
When water temperature reaches the first preset value, manipulating driving motor makes the minimum by luminous power of collecting plate, to make working media radiate, it is necessary to
The number of startup circulating pump 30 is few and its run time is greatly reduced, and favorably saves electric energy.
It should be noted that the water temperature in water tank 20 manipulates heating pipeline circulation heating less than the first above-mentioned preset value
During water, controller can also manipulate driving motor and rotate, adjust collecting plate by luminous power, make the light work(of collecting plate
Rate value reaches maximum, quickly to heat the water in water tank, the water temperature of water tank is reached the first preset value, particularly the winter
When it or cloudy day.
