ENERGIEEINSPARUNG BEI DER RAUMHEIZUNG IM MIT OEFFENTLICHEN MITTELN GEFOERDERTEN MEHRFAMILIENHAUSBEREICH UNTER EINSATZ VON MONOVALENTEN ELEKTRISCHEN WAERMEPUMPEN MIT WAERMEQUELLE LUFT
The interaction between the heat pump and the building to be heated is very important for the performance of the total system and should be studied. VEW, Germany is investigating this interaction in two existing apartment buildings where electrical heat pumps with air as a heat source have been installed, which use existing radiators for the distribution of heat. The operation of the heat pumps is monovalent and with an outdoor temperature of -12 degrees C the heat is delivered at 48 degrees C. The two apartment buildings have 36 and 44 dwellings respectively and are heated with 4 and 5 heat pumps of 50 kW. A heat storage system has been installed to avoid operation of the electrical heat pumps at peak hours. It was found that the control of this system is difficult but not impossible; a more sophisticated control system is required. The influence of the lay out on the performance is very large. The seasonally averaged COP was 2-2.2.
