Problem Description:
What is installed in the wall-mounted solar water collector heating ? AVERAGE ?
Analysis:
Generally, solar energy is heated by directly using water to flow through the collector tube. Wall-mounted solar is no exception, but some solar uses other media to collect heat and then heat water through a heat exchanger. Most of it is filled with petroleum substances, which are easier to use due to their high boiling point. There is a bracket inside the wall-mounted solar panel. Solar wall mounts use thermal fluid whose basic component is propylene glycol, which has similar performance to antifreeze (ethylene glycol) added to cars. However, it does not corrode and has a lower freezing point.It will not have any adverse effects. on copper thermal tubes and heat collecting plates. However, because it is a split type, there is heat loss during the heat conduction and heat exchange processes, and its thermal efficiency is not high if the water is used daily, it can rarely reach 60 degrees.
