green cooling initiative: Best practice example

Success story: CO2/ammonia cascade systems

Research and Training Platform using natural refrigerants with particular emphasis being laid on the use of CO2 as refrigerant.

A research and training platform using CO2 as refrigerant has been installed at the Université des Mascareignes in Mauritius. This project has been financed through the HPMP (HCFC Phase Out Management Plan) for Mauritius through the Ministry of Environment.

The system has been designed to operate in three different modes: Ammonia in direction expansion, a Cascade CO2 operation with Ammonia Cooling the CO2 and CO2 in transcritical mode. The system is completely instrumented with temperature and pressure sensors as well as flow meters to enable trainees to do different kinds of manipulations.
