Heat extraction distributed thermal response test: A methodological approach and in-situ experiment
(International Ground Source Heat Pump Association, 2017)
The Thermal Response Test (TRT) is a worldwide adopted in-situ methodology able to estimate the ground thermal conductivity and borehole thermal resistance. During the test the carrier-fluid exchanges a constant heat flux ...
Pulsated Thermal Response Test experiments and modelling for ground thermal property estimation
(International Ground Source Heat Pump Association, 2018)
The Thermal Response Test (TRT) is a well known experimental technique for estimating both the ground thermal conductivity and the effective borehole heat exchangers (BHE) resistance in ground coupled heat pump (GCHP) ...
Investigation on the effects of different time resolutions in the design and simulation of BHE fields
(International Ground Source Heat Pump Association, 2017)
The correct design of a field of Borehole Heat Exch angers (BHE) requires the knowledge of ground thermal properties, heat pump performance and building heating and cooling demand. The sequence o f heat pulses from (to) ...
Extending the Ashrae Tp8 method for vertical borefield design to uniform BHE temperature boundary conditions
(International Ground Source Heat Pump Association, 2018)
The Ashrae method is a fast algorithm for calculating the overall length of closed-loop borehole heat exchangers, considering the ground thermal response and the building thermal load profile. The method includes a corrective ...
Thermal Response Test experiments and modelling applied to shallow geothermal piles of different geometry
(International Ground Source Heat Pump Association, 2018)
Geothermal piles are structural elements that encountered interest in ground source heat pump (GCHP) applications thanks to the great potential in cost reduction compared to the traditional solutions based on borehole heat ...
