What will be the future of home air conditioning?

by Amili R. SEO

With the increase in living standards and productivity, one of the major areas of energy consumption is air conditioning. Air conditioning has become a necessity in today’s times and it needs to be efficient – probably employing at least half if not a third as much energy as we use today.

Air conditioners are possibly the ideal climate change irony. More than 70 percent of the world’s population will reside in cities by 2050, and most of the urbanization is taking place in hot regions like India. If the megacities of the future are going to whine along competently, they’re unquestionably going to need air conditioning.

This clearly means that the demand for cooling is only going to surge in future. But at the same time, air conditioner manufacturers in India would have to get emissions under control while using a fraction of energy they do right away. At present, USA takes up more power for cooling than Africa does for all things.

Fortunately, technological answers are available, and they don’t all need to involve some decorative new device. The point is, humans were bringing smart ways to cool spaces without energy for epochs. It’s something the architects of tomorrow are increasingly paying attention to.

The interior space is found to stay 20 degrees cooler than external region thanks to older stepwell technology clubbed into the modern design. The stepwell, or baoli, is actually a pond of water enclosed by a descendant set of steps, and as the water evaporates the air around it cools.

There’s another way to cool a space without the need of energy. Other passive cooling systems are based on wind, water, and heat sinks in diverse ways to create interior micro-climates. These clever designs take advantage of whatever the local scenarios happen to be to optimize comfort and reduce energy consumption.

now, it’s time to go a bit technical with advancements in air conditioners in India.

· For a minimum of two decades, we will slowly switch to refrigerants with global warming potential (GWP) less than 150. At present, we make the use of refrigerants with GWP>3000

· A big portion of people in India still do not use refrigeration and air-conditioning, so the use is bound to rise in coming years.

· As we would start switching to renewable energy, the use of vapor absorption systems and vapor adsorption systems will surge.

India is one of the countries that have been roofed by the EU ratification of the Paris Climate Accord and perfectly so because it leads to 6.8% of Global Carbon Dioxide emissions (Source - Wikipedia). India is expected to have a concrete plan to bring down its carbon emission per unit GDP by 33–35% starting from 2005 to 2020. We are also supposed to augment our forest cover by 5 million hectares. We were supposed to generate 100 gigawatt from solar, 60 gigawatt out of wind, 10 gigawatt biomass and 5 gigawatt from small hydropower by the end of 2022.
