Air conditioning giant Gree has been named grand winner of the 2021 Global Cooling Prize (GCP), a ground-breaking innovation competition designed to develop a climate-friendly residential cooling solution.

Gree is represented in the UK by Klima-Therm. Its ‘Zero Carbon Source’ cooling technology integrates advanced vapour compression refrigeration, photovoltaic direct-driven, evaporative cooling and ventilation using renewable energy and free cooling sources.

The company explained: “The vapour compression refrigeration system… uses an ingenious compressor with a low global warming potential refrigerant in conjunction with improved design of evaporator and evaporative condenser to more effectively control indoor temperature and relative humidity.

“Furthermore, the photovoltaic direct-driven technology further lowers the overall grid electricity consumption. This climate-adaptive residential air conditioner has five times lower climate impact than today’s conventional air conditioners.”

It added: “Gree’s cooling solution highlights how the upper efficiency limit of today’s predominant technology—vapor compression technology—can be largely expanded through smart, hybrid design.

Ms Dong Mingzhu, chair and president of Gree Electric Appliances, said: “Gree is a diversified technological global industrial group that has expanded its business to household consumer goods and industrial equipment, and it insists on continuous innovation and R&D to improve people’s lives.

“The climate-friendly air conditioning technology awarded the Grand Winner at the Global Cooling Prize will reduce the carbon emission impact of existing air conditioners by 80%.”

The GCP is committed to developing breakthrough innovative cooling technologies that have five times less climate impact than standard air conditioning units available on the market toda.

It was launched in 2018 by Rocky Mountain Institute, the government of India and Mission Innovation, a global initiative working to accelerate the development of clean energy.

Gree, the world’s largest manufacturer of residential air conditioners, has more than 570 laboratories, 8,000 R&D engineers, 52 research centres, 20,000 technology patents including over 6,000 invention patents.

Gree is dedicated to producing pioneering products and a comprehensive range of air conditioning solutions. All its systems are designed to provide the highest energy efficiency class on the market.

The competition offers up to $3 million in prize money and is designed to incentivise the development of a residential cooling solution that will have at least five times less climate impact than standard currently available residential/ room air conditioners units.
