On rainy daysyou can use solar energy to take a bath, but it is still not recommended.
During thunderstorms, it is recommended not to use electrical appliances or solar water heaters for bathing, as you are concerned that lightning protection facilities may not be perfect and can cause lightning. However, current transmission lines, including many household appliances or equipment, have good lightning protection designs, so there is no problem in normal use.
Of course, if you can use it, it's good to be patient. If the lightning protection installations prove to be defective, an accident may occur.
Since the birth of life on earth, it has mainly relied on the energy of thermal radiation provided by the sun. Since ancient times, humans have also knownalally use sunlight to dry objects and use it as a method. to prepare food, such as making salt and drying salted fish.
Working principle:
Sunlight passes through the first glass layer of the heat-absorbing tube and shines on the black heat-absorbing layer of the tube. second layer of glass. Thermal absorption of light energy, because the two layers of glass are vacuum insulated, heat transfer will be greatly reduced (radiant heat transfer still exists, but there is no heat conduction and convection thermal), and most of the heat can only be transferred to the glass tube. The water inside heats the water inside the glass tube.
The heated water becomes lighter and flows upward along the heating surface of the glass tube into the insulated water storage bucket. Water at relatively high temperaturet bass in the bucket enters the glass tube along the backlit surface of the glass. tube for replenishment. In this continuous cycle, heat conservation. The water in the water storage barrel is continuously heated to achieve the hot water target.
