The heat-absorbing coating of long-term air-dried solar energy will also attenuate, and the heat-absorbing effect will be reduced after a long time.

The advantage of using copper coil is antifreeze, the copper coil is placed in the water tank and connected to the collector, and the antifreeze is installed inside, which is a double-circuit system.
Here's how to add it:
1. Determine the minimum air temperature for the local area, and on the basis of the minimum temperature, float down 5 10 and choose antifreeze. If the local minimum temperature is -15, choose the freezing point of antifreeze, which cannot be higher than -20, so as not to cause the antifreeze to become viscous and affect the use of extreme weather. >>>More
Hello, "Black Porcelain Old Man" reminds you: the wall-mounted solar medium is made of heat conduction fluid, the basic component is propylene glycol, which is similar to the performance of antifreeze (ethylene glycol) added by automobiles, but it is not corroded, and the freezing point is lower, and it will not have an adverse effect on the heat conduction copper tube and heat collector plate. However, because it is a split type, there is heat loss in the process of heat conduction and heat exchange, and its thermal efficiency is not high, if you use water every day, it can rarely reach 60 degrees.
