Abstract :
Ground coupled heat pumps are growing strongly due to its high energy performance, low power consumption and contribution to reduction in CO2 emissions. The ground heat exchanger sizing is a critical factor for the optimal system operation. Current methods for measure the thermal conductivity of soil, are expensive and do not allow to take advantage of the thermal behaviour of different geological layers, groundwater or dynamic features.
