Sustainable Cooling Technologies – Natural Refrigerant Air Conditioning
The participants are made aware of the environmental, spatial and structural implications of using this
Technology, in comparing the conventional HVAC systems for building design. The participants are made
to realize that these are already commercially available and implementable technologies, further emphasizing
that they are sustainable technologies and not alternative technologies. The environmental benefits of using this technology as it replaces f-gases, along with different safety implications and application constraints are also covered.
Unitary and Centralized systems are focused upon, with a special module on R-290 based refrigerant technology. The need to leapfrog to natural refrigerants is also highlighted. The issues with usage of carbon dioxide as a natural refrigerant and lack of commercial application examples are also delved into.
