Solar energy plays a very important role in our daily lives. For us, solar energy is a very important natural energy source, giving us great convenience in life. Solar water heaters are widely used, and solar cooling is also being gradually promoted. Solar DC Freezer is the application of solar energy in refrigeration.

Its basic principle is to collect solar radiant energy and convert it into heat energy through interaction with the matter for use. Currently, the most commonly used solar collectors include four types: flat plate collectors, evacuated tube collectors, ceramic solar collectors, and focused collectors (trough, dish, and tower).

China is rich in solar energy resources, and the prospects for solar energy utilization are broad. However, natural resources are not inexhaustible, so we must use resources rationally and care for the environment. I believe that with solar energy, China freezer can be better.
