Desarrollo de equipo para la realización de test de respuesta térmica del terreno (TRT) en instalaciones geotérmicas

Abstract

The use of the ground as heat source in

air-conditioning has become a renewable

energy resource increasingly booming since

it maintains a stable temperature in both

winter and summer, from a certain depth. For

the design of facilities that take advantage of

this resource is necessary to know the thermal

characteristics of the ground (conductivity,

diffusivity and undisturbed ground temperature,

etc.), from them the ground heat exchanger

(GHE) is dimensioned (depth, diameter and

number of boreholes).

In this sense, it has been developed and built

a system that allows make ground thermal

response tests (TRT), to obtain ground

characteristics mentioned above. This paper

describes the design of the equipment and the

computing software that obtains the required

results.
