How all the cooling equipment in the world is heating up the planet

The transition to efficient cooling presents a compelling business opportunity. Not only do organisations have another way of reducing operational energy requirements but the cooling industry has another chance to innovate and grow. India has shown the ability to “leapfrog” when it comes to technology transitions. The mobile phone and LED revolutions have become legendary. Cooling presents a similar opportunity. India is one of the first countries in the world to introduce five-star rated room air-conditioners and is among the first developing countries to develop the new generation, climate-friendly refrigerant HFO-1234yf for air-conditioners to be used in cars for sale in Europe.

Energy Efficiency Services Limited (EESL), established in 2009 as a joint venture of four national public-sector undertakings, is looking to aggregate demand for super-efficient room ACs, leverage economies of scale and bring the initial cost of the super-efficient air-conditioner close to the units being sold in the market today. This is the same path EESL had taken to trigger the LED revolution.

Chillers are among the most intensive energy consuming equipment in large organisations. Therefore it’s not only important to ensure energy efficient and optimal performance, it is also critical to replace older chillers with the latest equipment available in the market today. The investment pays off in less than 2 years’ time. Mahindra and EESL has signed an agreement to install and service a tri-generation project of 803 kW capacity. Tri-generation engines use natural gas as the energy source, generate electricity and simultaneously address heating and cooling requirements. The system more than doubles energy conversion efficiency compared to existing systems.

While there are a number of superior cooling technologies available already, the search for better technologies continues. The Department of Science and Technology and other nodal ministries of the Government of India are supporting the Global Cooling Prize. The prize envisions a ‘5X solution’ – a cooling solution that has one-fifth of the climate impact of the commonly sold room AC units in the market today, taking into account both the electricity consumption and the global warming potential of the refrigerant used.

The Climate Group’s ‘Cooling Challenge’ has come at a most appropriate time. Many organisations around the world, including Godrej and Mahindra from India, have promptly signed up to the challenge as soon as it was announced. Cooling can be the next big thing in energy efficiency. Concerted action to increase cooling efficiency will go a long way in helping countries achieve Paris agreement commitments and will also help organisations move towards doubling energy efficiency. The heat is truly on better cooling!
