LA AEROTERMIA COMO ALTERNATIVA A LA CONTRIBUCIÓN SOLAR PARA AGUA CALIENTE SANITARIA (ACS) EN EDIFICACIÓN TERCIARIA

Abstract

Aerothermy is considered as a source of renewable energy that harnesses the energy contained in the air for other uses, such as hot water production, heating and cooling of buildings. Aerothermy is based on technologies that take advantage of air temperature for its transformation into energy, with a reduced percentage of electric energy consumption for its operation. The Technical Building Code (TBC), currently in force in Spain for the design of new buildings, in its Basic Document HE: Energy Saving, chapter 4 requires for the buildings a minimum solar contribution for the production of domestic hot water (DHW). This contribution depends on the location and total demand of DHW of the building. In turn, the DB-HE 4 allows that the solar contribution for the generation of DHW can be supplied by the use of renewable energies. This paper presents, through a case study, the technical, normative and economic feasibility of aerothermy as an alternative for the generation of DHW by thermal solar panels in tertiary building.
