Thermal influence of neighbouring GSHP installations: Relevance of heat load temporal resolution
(International Ground Source Heat Pump Association, 2018)In densely populated areas where many ground source heat pump (GSHP) systems are present, it becomes important to consider the thermal influence of neighbouring GSHP installations while designing these systems. This question ... -
Near-instant g-function construction with artificial neural networks
(International Ground Source Heat Pump Association, 2018)A g-function is a useful tool that simplifies the calculations of heat exchanges in a ground-coupled heat pump system. In this work, we show how an artificial neural network can be trained to construct a g-function with ... -
Full-scale model to predict borehole fluid temperature with groundwater advection
(International Ground Source Heat Pump Association, 2018)Ground source heat pump (GSHP) system is one of the major techniques that utilize shallow geothermal energy and borehole heat exchangers (BHEs) is the key component in GSHP system. Although most proposed analytical models ... -
G-functions for bore fields with mixed parallel and series connections considering axial fluid temperature variations
(International Ground Source Heat Pump Association, 2018)A semi-analytical method based on the finite line source (FLS) solution is presented to evaluate thermal response factors for geothermal bore fields with mixed series and parallel connections between boreholes. Each borehole ... -
Upgrade of the B2G dynamic geothermal heat exchanger model: Optimal location of the ground nodes
(International Ground Source Heat Pump Association, 2018)In order to optimize the design and operation of a ground source heat pump system, the modeling of the Borehole Heat Exchanger (BHE) and its coupling to the heat pump operation becomes crucial. This becomes key for those ... -
Seasonal performance assessment of a dual source heat pump system for heating, cooling and domestic hot water production
(International Ground Source Heat Pump Association, 2018)In order to contribute to a global CO2 emissions reduction in 2020, the increase in the use of highly efficient heat pumps for heating, cooling and domestic hot water production in buildings is very recommendable. In this ... -
Randomly fractal approach to calculate the thermal conductivity of moist soil
(International Ground Source Heat Pump Association, 2018)Ground coupled heat pump (GCHP) is an energy saving technology that uses the shallow geothermal energy for the building heating and refrigeration systems. An optimized design of ground heat exchangers (GHEs) is the key to ... -
Ates system monitoring project, first measurement and performance evaluation: Case study in Sweden
(International Ground Source Heat Pump Association, 2018)Performance of Aquifer Thermal Energy Storage (ATES) systems for seasonal thermal storage depends on the temperature of the extracted/injected groundwater, water pumping rates and the hydrogeological conditions of the ... -
Hybrid model for generating short-time g-functions
(International Ground Source Heat Pump Association, 2018)A hybrid numerical/analytical approach is proposed to predict short-time g-functions. Transient heat transfer in the borehole is solved numerically while ground heat transfer is evaluated analytically using the infinite ...
