GreenCape, with the support of the City of Cape Town has published an energy efficiency themed case study.
This case study looks at how Pick ‘n Pay Ceres’, through support from Energy Partners Refrigeration, was able to reduce average refrigeration energy consumption by ~35%. This was achieved through the installation of a new efficient refrigeration system, provided
on a shared savings model.
The specific technical solution selected was a proven air-cooled, direct expansion multiplex rack configuration, with design evaporation temperatures of -10C for the medium temperature loads and -32C for low temperature.
Some of the key business benefits achieved included:
- Improved refrigeration system reliability, resulting in reduced stock losses and avoidance of reputational damage.
- Reduction of average refrigeration electricity consumption by 35%.
- Overall reduction in cost per refrigeration-hour of 30%.
- Ability to apply capital in other areas.
- Lower environmental impact from reduced energy consumption and refrigerant leakage.
- Reduced overhead requirements due to outsourcedmonitoring and maintenance.
