Heat Recovery Impact On Ecoefficiency Of Retail Refrigerating Units

Heating is a major CO2 source in the EU, with conventional methods producing substantial emissions. Supermarkets can reduce their impact by recovering heat from refrigeration systems.

This report explores heat recovery using R455A and R744 refrigerants in various climates. It shows that systems should use floating condenser pressure for efficiency, not increased pressure for heat recovery. Key findings:

· R455A saves more electricity than R744 in all climates
· Heat recovery can meet 100% of hot water and up to 69% of heating needs
· Dedicated heat pumps are more efficient than raising condensing pressure
