Heat recovery on CO2 systems in supermarkets.

Author(s) : REINHOLDT L., MADSEN C.

Summary

Supermarkets consume approximately 4% of the total amount of electricity used in Denmark (corresponding to approximately 1350 GWh/year). From that amount approximately 450 GWh is used annually solely for refrigeration and freezing purposes. With the use of transcritical CO2 systems in supermarkets heat recovery on refrigeration systems is becoming more attractive as it is possible to produce heat at high temperatures. This paper covers the investigation of the heat recovery possibilities on CO2 refrigeration systems with a view to reduce the energy consumption in supermarkets e.g. the energy used for air conditioning, hot water consumption, floor heating etc.
