This paper summarizes a case study of an innovativeground-source heat pump (GSHP) system that uses floodedmines as a heat source and heat sink. This GSHP systemprovides space conditioning to an existing 56,000 ft² (5203m²)research facility, in conjunction with existing space heatingand space cooling systems. Heat transfer performance andoverall efficiency of the GSHP system were analyzed using theavailable measured data from January through July 2014. Theperformance analysis identified some issues with using minewater for cooling and the integration of the GSHP system withthe existing steam heating system. Recommendations weremade to improve the control and operation of the GSHPsystem. These recommendations, in conjunction with the availablemeasured data, were used to predict the annual energy useof the system. Finally, the energy and cost savings and CO2emission reduction potential of the GSHP system were estimatedby comparing them with a baseline scenario. This casestudy provides insights into the performance of and potentialissues with the mine-water-source heat pump system, which isrelatively underexplored compared to other GSHP systemdesigns and configurations.
