A Novel Integrated Frozen Soil Thermal Energy Storage and Ground-Source Heat Pump System
MetadataShow full item record
In this paper, a novel integrated frozen soil thermal energy storage and ground-source heat pump (IFSTS&GSHP) system in which the GHE can act as both cold thermal energy storage device and heat exchanger for GSHP is first presented. The IFSTS&GSHP system can serve as cold energy thermal storage at night, produce chilled water in the daytime in summer and provide hot water for heating in winter. This is followed by its schematic and characteristic description. Then the various operation modes of such system according to different operational strategies are demonstrated in sequence. The system, firstly seen in open literature, is energy-saving, environmental-friendly and promising in the field of air-conditioning systems, and will help solve the problems currently existing with the GSHP system and ITES air conditioning system.
