Ozone Day: Natural Refrigerants can pave the way for a green future: Ravichandran Purushothaman

On the occasion of Ozone Day, Danfoss India spreads awareness on what it takes to make the shift from artificial to natural refrigerants

Danfoss India_Logo On the occasion of Ozone Day,  time has come to retrospect one  major challenge faced by the  refrigeration and air conditioning  industry worldwide which is the on-going pressure to accept Low Global Warming Potential (GWP) Refrigerants that have lesser impact on the environment.

In the process of adhering to the guidelines set by the Montreal Protocol, developed countries widely use R410a refrigerant in air-conditioning as R22 has been phased out. However there are concerns over R410a’s higher GWP of 2100 Vs 1810 of R22. A safer alternative is CO2 which is favourable due to thermo physical properties.

Developments in CO2 technology have surprised many in the industry, and have, in some cases, disproved the notion that CO2 is thermodynamically unsuitable as a refrigerant. Rather, CO2’s favourable thermo physical properties support the use of the refrigerant. In certain applications, CO2 offers heat recovery capabilities, which can decrease emissions and energy bills by reducing heating costs.

Companies in India especially those which export to the EU should be aware of the F-gas regulation, especially the timelines and the bans it defines. Not all bans have yet to be clearly defined, but, despite most sectorial bans being some years away, the market is expected to begin reacting very soon.

“There is a need to create awareness about  this regulation among India Inc. We need to  closely monitor how this law is interpreted  into actual market solutions and if rightly  done, natural refrigerants can pave the way  for a green future”, said Mr. Ravichandran  Purushothaman, President, Danfoss India.

More than a decade ago, Danfoss developed a method of evaluating the business risk of low-GWP solutions, taking into account all factors within technology, safety and cost.

Danfoss Refrigeration and Air-conditioning Controls Division has understood the need for developing environment friendly components and solutions. Automatic Controls portfolio from Danfoss includes Thermostatic Expansion Valves, Solenoid Valves, Ball Valves, Check Valves, Sight Glass and Filter Driers, for commercial air conditioning applications. There is a need for companies to stay committed to research and develop products for low-GWP refrigerants, both natural and synthetic, to fulfil customers’ needs for practical and safe solutions without compromising on energy efficiency.
