Higher than in the attemperater 11 during water temperature predetermined value, to the upper flow of heat collector branch pipe 232, it is responsible for through the heat collector
231 flow into the circulating water pipelines 23, and the hot water in the circulating water pipeline 23 injects the attemperater 11, the insulation water
Cold water in case 11 then flows into the circulating water pipeline 23, and the cold water supplement in the circulating water pipeline 23 injects the heat collector
Supervisor 231, the cold water supplement that the heat collector is responsible in 231 are injected in the heat collector branch pipe 232, form Model for Thermo Stratified Flows and follow
Ring.
Further, the outdoor temperature sensor 32 and the outdoor optical sensor 33, the outdoor are provided with outdoor
Temperature sensor 32, the outdoor optical sensor 33 and optical sensor 22 is equal in the heat collector in the heat collector 21
It is connected to the controller 31.The controller 31 sets snow removing function on temperature value as 5 DEG C, is sensed in the outdoor temperature
When device 32 detects temperature value less than 5 DEG C, it is determined as winter.The controller 31 detects the illuminance of the outdoor optical sensor 33
Value, when the illuminance value of the outdoor optical sensor 33 is less than the first outdoor preset value, is determined as night, the solar energy heating
The normal work of device 100；The illuminance value of the outdoor optical sensor 33 is outdoor to be fine higher than during preset value, judging outside second Room
It and have sunlight, the normal work of solar energy heat collector 100；The illuminance value of the outdoor optical sensor 33 is between described
When between the first outdoor preset value and the outer preset value of the second Room, judge outdoor for cloudy without sunlight.The controller 31 is visited
Survey the illuminance value of optical sensor 22 in the heat collector, the illuminance value that optical sensor 22 detects in the heat collector is less than pre-
If during illuminance value, the controller 31 judges the array heat collector by snow cover, startup snow removing program.
For the first outdoor preset value set as 10000lux, the outer preset value of second Room is 50000lux.
Further, the attemperater component 10 also includes described described the temperature inside the box inside attemperater 11
Sensor 17, level sensor 18 and electric heating tube 16, the mouth of pipe of water inlet pipe 12 are provided with entering water electromagnetic valve 15, the water inlet
Magnetic valve 15 is connected with the controller 31 and controlled by the controller 31.The controller 31 passes through the level sensor
Water level in the 18 detection attemperaters 11, when the water level in the attemperater 11 is less than 20%, enter water power described in startup
Magnet valve 15, it is the moisturizing of attemperater 11；The controller 31 detects the insulation by the temperature inside the box sensor 17
Water temperature in water tank 11, when water level is less than 45 DEG C in the attemperater 11, starts the electric heating tube 16 and heat.
The controller 31 starts the heat-collecting pump 14, makes the hot water in the attemperater 11 through the circulating water pipeline
23 are back to the heat collector 21, and the heat of hot water is sent to the thermal-arrest fin, the thermal-arrest by the heat collector branch pipe 232
Air heat-exchange between heat and the glass cover-plate that device fin is obtained, the glass cover-plate inside and outside is exchanged heat, make described
Accumulated snow on glass cover-plate absorbs heat and melted.Water after heat exchange cools down is in the case where the pressure of the heat-collecting pump 14 promotes, backflow
To the attemperater 11, water temperature remains above or during equal to 45 DEG C in the attemperater 11, continues on through the circulating water pipeline
23 are back to the heat collector 21, if be less than 45 DEG C, after the electric heating tube 16 heating, then by the note of heat-collecting pump 14
Enter the circulating water pipeline 23, until the accumulated snow on the heat collector 21 all melts.The controller 31 monitors the thermal-arrest
When the illuminance value that optical sensor 22 detects in device is consistent with the illuminance value that the outdoor optical sensor 33 detects, the control
Device 31 exits snow removing program, into normal operating conditions.
In the program that removes the snow, due on the heat collector 21 covered with the glass cover-plate, by glass transmission rate and room
The influence of the environmental conditions such as outer dust, the illuminance value that the controller 31 is monitored by optical sensor 22 in the heat collector are led to
Often error be present between the illuminance value of reality, the error amount of the solar energy heat collector 100 can be according to external environment
Change be configured, be generally set between 5% to 10%.
For example, step-up error value is 5% in the controller 31, if optical sensor 22 detects in the heat collector
Illuminance value is compared with the illuminance value that the outdoor optical sensor 33 detects, and optical sensor 22 detects in the heat collector
Illuminance value and the illuminance value that detects of the outdoor optical sensor 33 between difference be less than or equal to the outdoor optical
The 5% of the illuminance value that sensor 33 detects, then it is assumed that the illumination that the heat collector 21 receives is consistent with outdoor illuminance,
Complete snow removing；If what the illuminance value that optical sensor 22 detects in the heat collector detected with the outdoor optical sensor 33
5% of difference higher than the illuminance value that the outdoor optical sensor 33 detects between illuminance value, then it is assumed that the heat collector
21 illumination received are less than outdoor illuminance, and snow removing does not complete.
The illuminance mentioned in the present embodiment is consistent or temperature is consistent, refers to the allowed band in setting in error amount
It is interior.For example, the error amount of illuminance value, between 5% to 10%, the error amount of temperature value is between 2% to 5%.
Fig. 3, Fig. 4 and Fig. 5 are referred to, a kind of controlling party of solar energy automatic snow provided in an embodiment of the present invention is shown
Method, it uses the above-mentioned solar energy heat collector 100 with automatic snow function, and the control method comprises the following steps：
