Evaluation of our solar water heater PPT, part three: expansion and extension

The use of solar heating in our country has developed rapidly and the energy saving effect is obvious. In the energy consumption structure of buildings, 75% of the energy is used for building heating and hot water supply. Combining solar energy utilization with building energy-saving technology can reduce energy consumption and environmental pollution, and is an important way to save building energy.

Mirage, referred to as mirage, is a natural phenomenon formed by the refraction and reflection of light. It is a virtual image formed by the refraction of light reflected by objects on the earth through the atmosphere.
