Abstract

Performance data for a horizontal "Slinky" GSHP system in South Dakota was collected to evaluate the overall performance of on a daily, monthly, and seasonal basis. The results of the performance check, analysis of input energy, and electrical cost and energy breakdown showed that the system was operating within it's [sic] design conditions. The analysis of the soil/pipe overall heat transfer coefficient showed a significant difference between the means of the heat transfer coefficients of frozen and unfrozen soils for the entire heating season as well as on a month-to-month basis. The analysis of run fraction verses loop length and heat transfer rates indicated that the steady-state run fraction value currently being used in the ground loop design equation should possibly be replaced with a run fraction factor which is a function of the run fraction.
