The air conditioner uses technology that turns solar heat into air conditioning with minimal electrical power use, thereby saving 90 percent of energy, said the company. The air conditioning system is powered by solar-heated water, water heated by surplus energy, or district heating water. The patented technology is able to create efficient cooling from solar heat with a combination of low-pressure turbines and water as a refrigerant. The system consists of two separate circuits. In principle, the driving circuit is the same as on a power plant. Heat creates steam that drives a turbine, but in this case the temperatures and pressure are lower; since the circuits operate under a vacuum, steam is allowed to be generated at low temperatures. The cooling circuit is a simple cooling process similar to that of a refrigerator, except here the media is water. To make water work as a refrigerant, the pressure is also very low in the cooling circuit. The surplus heat from the process, which is not reutilized in the system, can be used for other purposes such as heating water for household use.
