Some comments about the use of GHP in Alentejo (Portugal)

In this work we advocate the use of geothermal pumps to cool the isolated houses that can be observed in the plain of Alentejo. Passive cooling of the houses, made for centuries, becomes insufficient when it aims to promote tourism in the region. The climatic characteristics of the region and the relatively high values of the thermal conductivity of the ground favour this type of use. The available land around the houses provide places where you can drill or make trenches to put the pipes under the surface . Some values of pipe lengths were obtained using values appropriate for the region. The need to try to preserve the shape of the typical houses of the region discourages the use of solar panels placed on the roofs. The length and time of use of the equipment is another factor to take into account in the analysis of the costs.
