The latter might be the case if the borehole has become too short e.g. due to system changes or if it affected by other boreholes in the vicinity. TRNSYS simulations have been conducted in order to analyse the advantages in different systems for dwellings. In Sweden, interest in the combination of ground-source heat pumps and solar collectors has steadily increased in the residential sector in recent years. Several systems from different contractors are available on the Swedish market. Article by Elisabeth Kjellson, Sweden Source: IEA Heat Pump Centre Newsletter 25(2007)4 p. 23-25 | |
