Zistboom:Researchers at Tehrans Materials and Energy Research Center have designed and developed a solar ice-making machine.

Announcing the above, Dr. Ali Asghar Tofiq, the head of Materials and Energy Research Center, said researchers have created an ice-making machine that uses the heat from sunlight to power a chemical reaction, Mehr News Agency reported.

He also said the heat exchanger is filled with a liquid refrigerant material, adding that the convex reflective panel focuses light and heat energy from the sun onto the piping that aporizes the refrigerant.

"When the sun goes down, however, the vapor goes through massive heat loss due to pressure differences and about five kilograms of ice are produced, he said.

Tofiq further said the refrigerant rapidly cools, due to its unique properties, which makes it perfect for typical temperature ranges in warm climates.

There are no moving parts in the device to wear out and it can produce ice off the grid and also offers a kind of food storage.

"The lower cost of the device is also another advantage over other photovoltaic devices, as it does not use such photovoltaic cells, he said.

Tofiq noted that the ice-maker is applicable in far-flung areas and when disasters happen.
