I: Experimental modeling [Elektronische Daten] [Yiqun Tang, Jie Zhou, Modan Zhang, Yuting Liu] With the development and exploitation of geothermal energy ground source heat pump (GSHP) systems are being utilized all over Shanghai due to its unique energy advantages. A model experiment is designed and carried out to simulate an alternately-running GSHP system in summer and winter. It aims to study the characteristics of thermal conductivity and moisture migration of saturated soft clay (Shanghai mucky clay) with respect to thermal balance during the operation of a GSHP system by a series of laboratory modeling experiments. Thermal conductivity is an essential thermo-physical parameter for designing a GSHP system and is calculated [1.3680W/(m°C)] rather than obtained via the expensive and time consuming in situ thermal response test. The value measured in laboratory experiments [1.1200W/(m°C)] by transient probes did not comply well with in situ data. The Thermal conduction and moisture migration characteristics of Shanghai mucky clay indicate it is a geo-material with good heat storage but poor heat release based on a comparison between summer and winter conditions. All results provide reference for further discussion regarding the environmental effect of thermal balance surrounding a GSHP system. They are essential and valuable for the development of GSHP systems in Shanghai.
