Modeling and performance evaluation of fractured thermal energy storage (FTES)
(International Ground Source Heat Pump Association, 2022)
Fractured thermal energy storage (FTES) is an open-loop type system that uses hydraulically propagated horizontal fracture planes for storage and extraction of heat in low-permeability hard rock formations. Groundwater ...
Development of a topology optimization method for the design of ground heat exchangers
(International Ground Source Heat Pump Association, 2022)
A new method for sizing vertical ground heat exchangers is proposed using topology optimization to reduce the number of boreholes required to fulfill the cooling and heating demand. The ASHRAE sizing equation is adapted ...
Development and verification of control system for heat recovery ground source heat pump system
(International Ground Source Heat Pump Association, 2018)
An operation method and control system for heat recovery ground source heat pump (HR-GSHP) systems have been developed. By applying the operation method and control system, the heating and cooling output from the respective ...
Are shallow boreholes a suitable option for inter-seasonal ground heat storage for the small housing sector?
(International Ground Source Heat Pump Association, 2018)
In recent years, various researchers have studied the performance of Solar Assisted Ground Source Heat Pump (SAGSHP) systems using borehole heat exchangers. However, the research conducted has been limited to conventional ...
Case study on high-resolution monitoring network of groundwater heat pump system
(International Ground Source Heat Pump Association, 2022)
With the increasing installation of shallow geothermal energy, the importance of thermal impact prediction also increases in the system design stage. In nature, it is general that heterogeneity exists and it can affect the ...
Modelling and experimental validation of a novel co-axial spiral borehole heat exchanger
(International Ground Source Heat Pump Association, 2017)
In order to optimize the operation of a ground source heat pump (GSHP) system, the development of dynamic models that integrate all the system components is a key factor. Particularly, the modelling of the ground source ...
