Summary

In the scope of a demonstration project, an absorption resorption refrigeration system (RRS) has been further developed from the functional to the prototype status. The RRS was integrated into the heating, cooling and refrigeration structure of a supermarket. The main purpose of the integration was the increase in the annual efficiency of the Cogeneration plant (CHP) and the reduction of electrical energy consumption of the cooling system in the A/C level (3°C to 9°C) and medium temperature refrigeration (-6°C to 6°C). To distribute the cooling capacity a secondary refrigerant cycle is used, which allows additional R290 refrigeration units. A PCM cold storage unit was installed to further increase the flexibility of the generation of power, heating and cooling capacity. The implementation of the RRS is presented and the achieved cooling capacities are discussed depending on selected boundary conditions.
