Sažetak:
When heat pumps are used in refurbishment of complex HVAC systems in buildings, high ratio of produced thermal energy and consumed electric energy must be achieved, while operating conditions of existing installations which are usually not renewed have to be maintained. The results of energy efficiency study for hospital complex situated in Rovinj (Croatia) have been presented in the paper. Possible heat pump systems suitable for renewal of the existing thermal energy supply system have been presented and analyzed. New concept has been proposed. Existing boiler room and distribution pipelines, including radiators and hot water boilers in buildings would remain unchanged as the backup system. VRF heat pump systems with water loop as the heat source and sink would be added. Eventual lack or surplus of thermal energy in water loop is exchanged with sea water or a first stage heat pump. The reconstruction enables achievement of higher comfort level with still acceptable investment in energetic infrastructure. Numerical simulation has resulted in significant improvements in energy consumption compared with the case of systems renewal using the present concept.
