- Enfriamiento de un edificio de oficinas con un intercambiador de calor tierra-aire (ESHX) de gran diámetro: resultados de monitoreo para condiciones de verano calurosas y secasPublication . Duarte, Rogério; Gomes, Maria Glória; Rodrigues, Antonio Moret Rodrigues; Pimentel, FernandoLos intercambiadores de calor tierra-aire permiten amortiguar las oscilaciones de temperatura del aire exterior y enfriar edificios ubicados en climas cálidos y secos con muy pocos recursos además de los utilizados durante la construcción. A pesar del gran número de artículos científicos sobre intercambiadores tierra-aire, son pocos los trabajos que presentan datos de monitorización para intercambiadores funcionales con diámetro superior a 30 cm. El presente artículo presenta y discute datos de monitorización de un intercambiador de calor tierra-aire de gran diámetro construido para el enfriamiento de un edificio de oficinas existente. Los datos presentados fueron obtenidos durante un período característico de verano caliente y seco en el sur de Portugal. Se muestra que los gradientes de temperatura entre el aire exterior y el aire de salida del intercambiador alcanzan 9 K y que la capacidad de enfriamiento excede los 27 kW. Se discute el aprovechamiento de esta tecnología para el enfriamiento de edificios y se concluyen los beneficios a nivel de la reducción de las emisiones de CO2 y del consumo de energía asociado al enfriamiento de edificios en climas cálidos y secos.
- Avaliação do potencial de exploração dos recursos hidrominerais e geotérmicos e da sua utilização para temperaturas superiores a 25°CPublication . Madureira, P.; Cerdeira, R.; Lourenço, C.; Francisco, J.; Coelho, Luis Manuel RodriguesEnergy sustainability presents challenges as how to reduce resource consumption and how to make better use of renewable ones. For this purpose, the characterization of the existing endogenous resources is essential. The aim of this project was to evaluate the exploitation potential of hydromineral and geothermal resources and their use for temperatures above 25°C, in 39 concessions. The results allowed verifying that it is possible to optimize the use of energy contained in hydromineral resources in most concessions, namely in space heating, domestic hot water production and swimming pool water heating, as well as in buildings in the surrounding area, such as houses, hotels, swimming pools and greenhouses. This study was carried out as part of a project financed by Fundo de Apoio à Inovação, for and with the support of the DGEG and is intended to be a first approach to allow concessions carry out more detailed studies adapted to their reality.
- Geothermal energy use, country update for PortugalPublication . Nunes, João Carlos; Coelho, Luis Manuel Rodrigues; Carvalho, José Martins; Carvalho, Maria da GraçaThe presence of high-temperature geothermal resources, and the production of electricity from geothermal resources in Portugal, are restricted to the volcanic islands of the Azores Archipelago located in the North Atlantic Ocean. Three geothermal binary power plants are installed and running normally in the islands of S. Miguel and Terceira, the most economically developed, with a total capacity running of 26 MWe and an average production of about 200 GWh/year. The total production of those power plants in 2021 represented about 20 % of the total demand of the Azores archipelago. New nine vertical and directional wells were drilled in 2021 in both islands to increase the total running capacity of power plants, or at least saturate them, especially the Pico Alto geothermal power plant, Terceira Island. Following the call released in 2018 for geothermal projects, sponsored by the FAI – “Fundo de Apoio à Inovação”, to promote the use of geothermal resources in Portugal, namely the low enthalpy resources associated with Thermal Baths/Spas facilities, two district heating networks for hotels and public buildings are under completion: (i) Chaves (74 oC, 25 l/s) and (ii) S. Pedro do Sul (67 oC, 19.4 l/s). Furthermore, in Chaves, an independent small operation (110 kWth) was open in January 2022 in an emblematic museum located over an impressive former Roman Thermal Bath with innovations regarding the environmental management of the geothermal fluid and its disposal.Concerning GSHPs, the potential is huge and continues to be exploited, with new projects ongoing and new specific regulations are expected to be approved shortly. There are a few installations registered until now, but the technical data of the operations are scarce and do not represent the totality of what is installed in Portugal.
