This prototype, designed by a team of engineering students at San Jose State University, aims to make ice with energy exclusively from the sun. Its operation is summarized in the following paragraph:
“It uses a coolant that evaporates when exposed to the sun. The vapor passes through tubes that come into contact with an absorbent material, which cools down as the sun sets. Once the temperature of the absorbent material drops to 40 °, the refrigerant becomes liquid again and its temperature quickly drops below zero due to the pressure difference. Just put a little water outside the evaporator to get ice. “
This technology can also be used for the manufacture of air conditioners.
