filled bubbles. the lenses in these sheets are advertised to focus heat from the sun into the water and raise its temperature. do you think the lenses of such sheets do in fact direct more solar energy into the water?
No those can no longer via fact the whole component of the lenses isn't grater then the pool the whole image voltaic that falls on the pool maintains to be comparable, or perhaps much less via fact some gentle is absorbed in sheet. yet sheet can help in heating the water via fact it do no longer enable water to unfastened warmth via evaporation It acts as like a greenhouse shelter
yes, the radiant heat is collected in the airspace and the heat then moves from the plastic to the water. think of a car that has been setting(haha) in the sun with the windows up. when you get in the heat moves from the air in the car to your body. same process. question: will the heat leave the water faster than the water absorbs the heat?
If anything less solar energy is getting to the water as some of the energy will be wasted heating the cover itself. However the cover will keep in the heat of the pool as it is heated, so it does work, just not the way it's advertised to.
