Ghana has broken new ground with the installation of Africa's first eco-friendly air-conditioning chiller at the nearly Zero Emission Building in Accra. This pioneering system utilizes R290, a natural refrigerant, and is powered mainly by a photovoltaic system, exemplifying sustainable construction.
The project, part of the Sustainable Energy for Climate Protection initiative, was funded by Germany's BMZ and implemented by GIZ in collaboration with Ghana’s Ministry of Energy. The chiller boasts a 115 kW cooling capacity and is designed to reduce greenhouse gas emissions and improve energy efficiency, especially in tropical climates.
"The project demonstrates that R290 chillers operate safely and efficiently in Africa, reducing GHG emissions significantly," said Philipp Denzinger of GIZ Proklima.
Supported by GIZ Proklima and HEAT, with input from international and local experts, the chiller sets an example for future sustainable projects. Capacity building for local technicians ensures efficient long-term operation. The adoption of R290 chillers aligns with the Kigali amendment, aiming to phase out HFC chillers and contribute to Ghana's emission reduction targets, potentially cutting emissions by up to 60% in developing regions.
