“…Biomass appliances use wood logs or pellet as fuel and are divided into two groups: boilers (Haller et al 2011;Petrocelli and Lezzi 2014;Carlon et al 2015) and air stoves. The present paper focuses on the last-mentioned solution since it is the most diffused in the market, although boilers can be versatile with different integration such as solar heating (Persson et al 2019;Krarouch et al 2020) and new technologies as wood-pellet hybrid stoves (Lamberg et al 2017).…”

In the residential sector, biomass appliances are widely used for space heating and often combined with other systems. This work aims at comparing the final and primary energy consumption of different configurations, including a conventional and a ducted pellet stove and a wood log stove using air as heat transfer fluid. A dynamic analysis of the interaction between biomass stoves and conventional heating systems, such as gas boilers and radiators, is carried out within a typical single-family house in a mild climate, using TRNSYS software. In addition, natural ventilation of the building is considered using CONTAM, with a focus on external infiltrations and internal air circulation due to the buoyancy effect. Results show that the biomass device in one room promotes the airflows between adjacent thermal zones, enhancing the heat distribution through door openings, in particular when an air ducted stove is present. The final energy consumption resulting from simulations with wood-burning stoves is 21% higher than pellet stoves. The pellet stove results in similar final energy and a 30% increase in overall primary energy, while the wood stove increases the final energy by 22% and approximately 40% of overall primary energy compared to the case of a traditional gas system coupled to radiators which is considered as reference. Nevertheless, non-renewable primary energy savings are higher than 50% with pellet stoves and 60% with wood-log stoves.

“…Many studies have been reported on the analysis, design and estimate of the Moroccan regions potential to implant different solar technologies for various applications [6][7][8][9][10]. A. Allouhi et al [11] estimated the technical feasibility of solar water heaters (SWH) under Moroccan conditions in six different regions for two technologies: flat plate and evacuated tube collector.…”

This paper aims to report a detailed study of a Parabolic Trough Collector (PTC) prototype’s thermal system that requires a sizing and dimensioning investigation of its main parts. This PTC system possesses a field-type evacuated tube solar collector with U-shaped. Furthermore, a simulation study developed with TRNSYS is carried out to evaluate the validity and the feasibility of this system, in particular, for the low-temperature range. The solar collector is oriented to the south and follows the sun from east to west through a single-axis tracking system under real weather conditions. From the simulation results we noticed that for the operating configuration considered in this study, the solar fraction is significantly large throughout the year. During the summer, needs are covered almost 100 %. Whereas, it is necessary to integrate an auxiliary system for the winter period. The tank temperature reached a maximum of around 90 °C during the summer period. The system constantly ensures a heated floor temperature of around 28 °C. This reported simulation and analysis may enable to design and estimate of the region potential and the system productivity over the year, for different applications such as heating domestic water and underfloor systems.
