A study for the optimization of the ground thermal response in hybrid geothermal heat pump systems is presented. The design difficulty with hybrid geothermal heat pump systems is inherently an optimization problem that is best solved with a short time-step system simulation method. Many parameters can be optimized, and there is no unique expression of the optimization objective function. In this study, the optimization problem is defined as balancing the annual thermal loads on the ground by minimizing the borehole heat exchanger length and supplemental equipment size. The supplemental equipment examined in this research work has been limited to flat plate solar thermal collectors for heating-dominated applications and direct-contact evaporative cooling towers in cooling- dominated applications. Optimal control and operating strategies for the annual thermal load balance in the ground are discussed. Sensitivity analyses are conducted for the assessment of differential temperature control strategy impacting the magnitude of the ground heat transfer, and the supplemental equipment design.Units: SI
