Anonymous users2024-01-23The balcony wall-mounted solar is different from the vacuum tube solar energy, and the balcony wall-mounted solar temperature is generally about 60 degrees, because the long-term high temperature is easy to produce scale.

It didn't matter.
You don't have hot water in the collector, you go with antifreeze. >>>More
The price of balcony wall-mounted solar energy is generally high, and the price of the brand is generally around 5000-8000 yuan. The collectors of wall-mounted solar energy do not go out of the tube (no pipe bursting, safe operation), and the operation mode of the water tank is under pressure, which is much higher than the cost of ordinary falling water solar energy. The selling price is also much higher.
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
I think the inside of the balcony is definitely not as sunny as the outside, so hanging the balcony wall solar inside the balcony will definitely affect the absorption efficiency of solar energy.
