Optimising a supermarket refrigeration system with heat recovery to minimise operational costs.
Number: 0561
Author(s) : STEUER D., JOSEFSSON F., ARIAS J., SAWALHA S.
Summary
This work is a case study of a small supermarket located on the ground floor of a residential building in Stockholm. The supermarket has a CO2 refrigeration system with de-superheaters for heat recovery and water-cooled condensers/gas coolers using municipal water. The heat recovery system is connected both to the supermarket and to the residential building. This study evaluates the existing refrigeration system with field measurements data and investigates different system configurations and control strategies to minimise the operational costs from electricity and municipal water use. The results of the study demonstrate that the operational costs are reduced by 29 % in the existing solution, compared with no heat recovery, and that the costs can be reduced by further 31 % with a control strategy optimised for maximisation of heat recovery.
