Multi-year validation of a residential ground-source heat pump system with vertical closed-loop heat exchanger.

Number: pap. 393

Author(s) : MINEA V.

Summary

This paper presents the long-term design validation of a vertical closed-loop ground-coupled heat exchanger installed in a Canadian low-energy house. The house’s HVAC system integrates a brine-to-air geothermal heat pump as the house main heating and cooling system, electricity and heat generation from photovoltaic & thermal panels, passive solar energy storage and various heat-recovery devices. The paper focuses on the thermal behavior of the vertical ground-coupled heat exchanger during 5 consecutive winters. The results show that the ground entirely recovered its thermal capacity from one heating season to another. This may alleviate the common belief of long-term excessive cooling and/or freezing of ground in heating dominated climates.
