So basically I've seen that in Persia as well as in other areas, people have been using ice pools and other means to produce ice in the desert.
Specifically ice pools used the fact that deserts have low humidity, as this would mean higher evaporative cooling efficiency as well as radiative cooling efficiency. At day time a wall would ensure that the pool is kept under a shadow for the majority of the day. At night the water filled pool would radiate the heat into space bringing temperatures of the water bellow zero degrees C.
Would it be possible to reproduce these effects in a city with temperatures of let's say 20 degrees Celsius? What about 10⁰C? Especially considering the fact that humidity is relatively average to an European country.
Could the efficiency be increased by insulating the "pool" like let's say an insulated tray can?
