Water-based Air Conditioner cools without harmful Chemicals

A team of researchers from the National University
of Singapore (NUS) has pioneered a new water-based air-conditioning system that cools air to
as low as 18 degrees Celsius without the use of energy-intensive compressors and environmentally
harmful chemical refrigerants. This game-changing technology could potentially
replace the century-old air-cooling principle that is still being used in our modern-day
air-conditioners. Suitable for both indoor and outdoor use,
the novel system is portable and it can also be customised for all types of weather conditions. The research 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 per cent less
electricity than current compressor-based air-conditioners used in homes and commercial
buildings. This translates into more than 40 per cent
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. To add another feather to its eco-friendliness
cap, the novel system generates potable drinking water while it cools ambient air.

  • Looks awesome!

  • Hi Rajamanickam. Good info. I made an in depth review of this technology and its feasibility on my channel. Thanks!

  • To claim being world's first due point evaporative cooler, NUS R&D team needs to settle this priority with Maisotsenko Cycle coolers by Coolerado (15 years on international market) and a few other followers worldwide. NUS is about a few years (if not a whole decade) behind Valeriy Maisotsenko with his technologies using desiccants instead of rotors for dehumidification, heat recovery, water from air, 90% energy saving and plenty other implementations of thermodynamic Maisotsenko Cycle besides climate equipment.

  • Good inventions

  • as low as 18 celsius degree? but at which conditions had you conducted the experiments? And these conditions are common in humid climate in Singapore? I believe that these conditions don't exist. This prototype only works well, as it cooperate with a conventional AC, or with desccicant

  • Copycat from NREL’s study that has been published in April/2012 (Eric Kozubal, Jason Woods, Ron Judkoff). NUS’s paper has to be recalled !

  • In this system we need to give water as an input for continuous cooling effect??

  • the water is consumed?
