Assessment of the gradient of an objective function by analytical derivation for optimization-based design of ground-coupled heat pump systems
Dusseault, Bernard; Pasquier, Philippe; Marcotte, Denis (International Ground Source Heat Pump Association, 2017)Optimization-based design of ground heat exchangers requires derivation of the objective function with respect to the design parameters, which is usually done through finite-differentiation of the cost or utility function. ... -
Column experiments to anticipate clogging of standing column wells
Cerclet, Leo; Courcelles, Benoit; Pasquier, Philippe (International Ground Source Heat Pump Association, 2022)Standing column wells are a promising solution to reduce the environmental footprint of building energy consumption. Nevertheless, as in other open-loop wells, they can be affected by clogging processes if detrimental ... -
Control strategy evaluation framework for ground source heat pumps using standing column wells
Tonellato, Giulio; Kummert, Michael; Candanedo, Jose A.; Beaudry, Gabrielle; Pasquier, Philippe (International Ground Source Heat Pump Association, 2022)Standing column wells (SCWs) are efficient ground heat exchangers (GHEs) that have a significant cost saving potential. Recent developments have shown that they can also adapt successfully to cold climates despite previous ... -
Dynamic simulation of ground source heat pump systems with nonstationary convolutions
Beaudry, Gabrielle; Pasquier, Philippe (International Ground Source Heat Pump Association, 2022)Advective processes related to groundwater motion and flow rates have a significant impact on the thermal performance of ground source heat pump systems. Including these elements during the design phase, however, remains ... -
Forecasting hydraulic head changes in injection wells using LSTM network
Rose, Christopher; Pasquier, Philippe; Nguyen, Alain; Beaudry, Gabrielle (International Ground Source Heat Pump Association, 2022)Monitoring of well's specific capacity is commonly used to plan maintenance of injection wells in open-loop GSHP and standing column well systems. However, this method does not consider the effect of temperature on hydraulic ... -
Investigation of thermo-hydro-geochemical processes in a standing column well intersected by a fracture
Eppner, Fanny; Pasquier, Philippe; Baudron, Paul (International Ground Source Heat Pump Association, 2017)Local thermal and chemical conditions may favor minerals' scaling which can cause undesirable operational problems to standing column well systems. Precipitation may reduce heat exchange in the well and the heat exchanger ... -
Stationary and non-stationary deconvolution to recover long-term transfer functions
Dion, Gabriel; Pasquier, Philippe; Marcotte, Denis; Beaudry, Gabrielle (International Ground Source Heat Pump Association, 2022)To design a ground heat exchanger, simulations are frequently used. One way to perform simulations is to use the well-known g-functions to obtain the ground temperature. These functions are usually obtained by analytical ... -
Uncertainty assessment of the hydraulics properties surrounding a standing column well with a thermal response test
Jacques, Louis; Pasquier, Philippe (International Ground Source Heat Pump Association, 2022)The standing column well (SCW) is known for being a highly efficient ground heat exchanger as it relies on both conduction and advection heat transfer processes. Therefore, the interpretation of a thermal response test ...
