A new water-based air-conditioning system cools air to as low as 18 degrees Celsius (about 64 degrees Fahrenheit) without using energy-intensive compressors and environmentally harmful chemical refrigerants.
This technology could potentially replace the century-old air-cooling principle that is still used in modern-day air-conditioners. Suitable for both indoor and outdoor use, the new system is portable and can be customized for all types of weather conditions.
The team’s novel air-conditioning system is cost-effective to produce, and it is also more eco-friendly and sustainable.
The system consumes about 40 percent less electricity than current compressor-based air-conditioners used in homes and commercial buildings. This translates into more than 40 percent reduction in carbon emissions. In addition, it adopts a water-based cooling technology instead of using chemical refrigerants such as chlorofluorocarbon and hydrochlorofluorocarbon for cooling, thus making it safer and more environmentally-friendly.
The system also generates potable drinking water while it cools ambient air.
