OG&E Ground Source Heat Exchanger Study

A ground-source heat pump research project has been carried out at the Hope Crossing (Habitat for Humanity) site in Oklahoma City, OK. OG&E is coordinating the project and has gathered many collaborators to participate in the project. The following documents explain the background of the project and some preliminary results.

The Group is constituted of faculty, students and staff of the OSU College of Engineering Architecture and Technology (CEAT) with interest in building and environmental thermal systems. Individual faculty are members of the School of Mechanical and Aerospace Engineering (MAE) or Mechanical Engineering Technology (MET).

Simulation of Ground Source Heat Pump Systems

Sponsor:  U.S. Department of Energy

Investigators:  J.D. Spitler, S.J. Rees

Students: C. Yavuzturk, A. Chiasson, M. Ramamurthy, H. Jin

Description:  For several years, we have been developing models for ground loop heat exchangers, heat pumps, and other related components. These models are aimed at being used in component-based modular simulation environments such as TRNSYS or HVACSIM+. The ground loop heat exchanger model is capable of accounting for short (1 hour or less) time-step effects, while also accounting for very long-term (30 years+) borehole interactions.
Much of this work was funded by the U.S. Department of Energy. Six-page summaries of work done in 1998 and 1999 are available.

Evaluation of the Effects of Groundwater Flow on Closed Loop Ground Source Heat Pump Systems

Sponsor:  U.S. Department of Energy

Investigators:  J.D. Spitler, S.J. Rees

Students:  A. Chiasson

Description:  Aquifer flows are widely thought to have a beneficial effect on closed loop ground source heat pump systems. However, there has been little, if any work done to quantify the effects of the groundwater flow. We performed a study of the effects of groundwater flow on both in situ ground properties estimation and on the operation of the ground loop heat exchanger. The results are soon to be submitted for publication. This work is funded by the U.S. Department of Energy. A six page summary of work done in 1998 is available here.
