A solar-powered AC unit that could cut utility bills

Spanish inventors have created a highly energy-efficient Air conditioning unit.
The air conditioning unit’s heat pump spins, using centrifugal forces to dramatically improve the heat and mass transfer inside the unit, making it more efficient, leading to reduced utility bills.
The solar-powered model uses natural refrigerants that are harmless to the ozone layer and the unit operates without cooling towers.
Ac units used in US schools and businesses are routinely damaged by thieves keen to steal its copper, which costs $2.75 a pound. The US will be pleased to hear that although the Rotartica looks similar to standard units used in the country, the invention has no copper inside it. The machine was made in Spain for a coastal environment and has a steel outdoor coil.
A small camera inside the ac unit allows US researchers and Rotartica‘s inventors to monitor the unit’s performance from a computer screen 24 hours a day, seven days a week.
Researchers expect the Rotartica unit will be available for purchase in the US within two years.
