Feasibility of using ground source heat pumps in heating and cooling of residential buildings.

Number: No 326

Author(s) : KOOHI-FAYEGH S.

Summary

In many building types, heating and cooling demands are often unbalanced and using a single ground source heat pump (GSHP) to meet both heating and cooling demands introduces various options to designers in sizing the ground heat exchangers coupled to the heat pumps. Due such unbalanced heating and cooling demands, use of ground source heat pumps may not be feasible, or not financially feasible if coupled with a supplementary system. In this study, the impact of heating and cooling demands typical of a residential building on the feasibility of use of ground source heat pumps is studied. A typical residential building block in Ontario, Canada is modeled in eQuest 3.65. Simulation results of the models for space heating and cooling demand are used in RETScreen to arrive at a combination of technologies that may be able to provide heating and cooling to the buildings. Comparison of the approximate cost estimations for the various design options show the importance of employing customized coupling strategies in order to take maximum advantage of ground source heat pump systems and promoting their financial feasibility.
