Ground source heat pump (GSHP) systems are globally recognized as one of the most promising generation technologies in terms of economic and energy savings. However, operative performances can be lower than expected. The reasons can be ascribed to: i) an incomplete technological development; b) a not-optimized sizing and control strategies. A comprehensive approach to the optimal sizing and control methodologies has been discussed in previous works: remarkable economic and energy savings can be achieved with an optimized synergy between geothermal source and back-up generators. Furthermore, additional technological developments are required to improve current GSHPs performance. As well known, GSHP systems involve different subsystems: ground source, ground-coupled heat exchangers, heat pump unit, and back-up generators: this work aims at identifying the one that mainly affects the overall efficiency.

Abstract
Ground source heat pump (GSHP) systems are globally recognized as one of the most promising generation technologies in terms of economic and energy savings. However, operative performances can be lower than expected. The reasons can be ascribed to: i) an incomplete technological development; b) a not-optimized sizing and control strategies. A comprehensive approach to the optimal sizing and control methodologies has been discussed in previous works: remarkable economic and energy savings can be achieved with an optimized synergy between geothermal source and back-up generators. Furthermore, additional technological developments are required to improve current GSHPs performance. As well known, GSHP systems involve different subsystems: ground source, ground-coupled heat exchangers, heat pump unit, and back-up generators: this work aims at identifying the one that mainly affects the overall efficiency.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
