Top AC manufacturer Gree wins 2021 Global Cooling Prize

Air conditioning giant Gree has been named joint winner of the Global Cooling Prize, a ground-breaking innovation competition designed to develop a climate-friendly residential cooling solution. Gree shared the prize with Daikin India.

Gree, the world’s largest manufacturer of residential air conditioners, worked with Beijing-based Tsinghua University to develop a hybrid solution with three modes – vapour compression refrigeration, direct evaporative cooling, and ventilation – switching between each or operating them in parallel depending on external temperatures and environmental conditions.

Gree’s ‘Zero Carbon Source’ cooling technology exploits 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.”

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%.”

Gree 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 Global Cooling Prize, which is backed by entrepreneur Sir Richard Branson, is rallying a global coalition of leaders to solve the critical climate threat that comes from growing demand for residential air conditioning.

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.
