Working Principle

1.The collector applies the fourth generation of solar collector---heat pipe vacuum collector to transfer the solar power to heat energy.

2. When the temperature of TC(the temperature of the collector) is higher than that of TR(the temperature of the water tank), the controlling device will start the circulating pump.

3. The circulating pump makes the working medium liquid circulate in the system. 

4. The heat is transferred from the solar collector to the water tank by the heat exchanger

5. During the working process of the circulating pump, when the temperature difference is less than a set point, the circulating pump will stop.

6. When TR (the temperature of the water tank) reaches the highest of set point, the controlling device will close the circulating pump. 

7. The electrical heating device will automatically make the temperature of the above part of water tank stay at the set points.
