Benefits

The conventional vapour compression air conditioning system was invented more than 100 years ago. Today, air conditioning is considered a necessity in many places, including homes, commercial and industrial premises, as evidenced by the worldwide growth in the number of air conditioners, be it Room Air Conditioners (window type, split type and multi-systems) and Commercial Air Conditioners (medium/large-sized split type, remote condenser type, single packaged and VRF systems including unitary type and unitary type heat pumps).

The problems with conventional air conditioning systems are their high energy consumption, usage of HCFC/CFC chemical refrigerants under pressure and susceptible to leaking and causing ozone depletion and greenhouse effect and the throwing of heat to the outside ambient, resulting in global warming. As an illustration, assuming outside ambient air temperature is 32°C and inside air-con temperature is 25°C, conventional air-con will throw out heat of about 45°C at the external compressor. Whereas NUScool air-conditioner will cool the inside room temperature to the desired 25°C (or lower if desired) while expelling working air of about 28°C, which is still cooler than the 32°C outside ambient temperature.

NUScool air conditioners use our patented dehumidification technology and patented dew-point indirect evaporative cooler to provide dry and cool air, without using compressors nor HCFC/CFC refrigerants and do not throw out heat to the ambient. The eco-friendly and high energy efficiency ratio of NUScool air conditioners result in up to 40% lower energy consumption than conventional vapour compression air conditioners.

Applications

Studies have shown that typically 50% of total energy consumption in buildings is attributed to Heating, Ventilation and Air Conditioning (HVAC), of which 55% of HVAC energy is consumed by chillers of conventional air conditioners. Converting to high energy efficient NUScool air conditioners will significantly reduce energy consumption in residential, commercial and industrial buildings and also fight climate change.
