A new type of air-conditioned space using a radiant cooling/heating system with application in regions known for high differences in temperature throughout the day, has been studied. The effects of the number and position of the pipes within the walls have been analyzed using the finite element method (FEM). The results have shown that the number of the tubes has higher effect, approximately 30.5%. Furthermore, the location of the pipes in the inner surface of the wall has the effect of about 14.3%. In addition, the equation to predict the working fluid temperature within the pipes has been developed with about 89% accuracy.
