Dr. Ali Asqar Tofiq, Manager of the Substance and Energy Research Center says his organization has made an ice maker which uses the solar energy for Iran’s hot climates.
"Using the thermodynamic cycle, the device uses the solar energy to produce cold,” Tofiq said.
Asserting that there is no moving part in the device, he said "That is why its maintenance is much easier than other solar refrigerators.”
"The design is based on the surface absorption. The device uses activated carbon as the absorbent and methanol as the mobile agent,” he further said.
Tofiq stated "The elimination of solar cells and use of activated carbon instead is the most prominent characteristic of this ice maker. As photovoltaic cells are not used in the device, it costs less than the existing devices which use the cells.”
