A Novel Capacitive Model of Radiators for Building Dynamic Simulations

Thermo, Год журнала: 2025, Номер 5(1), С. 9 - 9

Опубликована: Март 11, 2025

This study addresses the critical challenge of performing a detailed calculation energy savings in buildings by implementing suitable actions aiming at reducing greenhouse gas emissions. Given high consumption buildings’ space heating systems, optimizing their performance is crucial for overall primary demand. Unfortunately, calculations such are often based on extremely simplified methods, neglecting dynamics emitters installed inside buildings. These approximations may lead to relevant errors estimation possible savings. In this framework, present presents novel 0-dimensional capacitive model radiator, most common emitter used residential The final scope paper integrate within TRNSYS 18simulation environment, 1-year simulation building-space system. radiator developed MATLAB 2024b and it carefully considers impact surface area, inlet temperature, flow rate performance. Moreover, dynamic heat transfer compared with one returned built-in non-capacitive available TRNSYS, showing that effect radiators leads an incorrect consumption. During winter season, system turned from 8 a.m. 4 p.m. 6 p.m., thermal underestimated roughly 20% commonly model.

HVAC System Energy Retrofit for a University Lecture Room Considering Private and Public Interests

Energies, Год журнала: 2025, Номер 18(6), С. 1526 - 1526

Опубликована: Март 19, 2025

The operation of Heating Ventilation and Air Conditioning (HVAC) systems in densely occupied spaces results considerable energy consumption. In the post-pandemic context, stricter indoor air quality standards higher ventilation rates further increase demand. this paper, retrofit a partial recirculation all-air HVAC system serving university lecture room located Southern Italy is analyzed. Multi-Objective Optimization (MOO) Multi-Criteria Decision-Making (MCDM) approaches are used to find optimal design alternatives rank these considering two different decision-makers, i.e., public private stakeholders. Among Pareto solutions obtained from optimization, alternative identified, encompassing three Key Performance Indicators using new robust MCDM approach based on four methods, TOPSIS, VIKOR, WASPAS, MULTIMOORA. show that, era, baseline scenarios for infection reduction that do not involve introduction demand control strategies cause consumption negligible values up 59%. On contrary, involving decrease between 5% 38%. findings offer valuable guidance retrofits education similar buildings, emphasizing potential balance occupant health, efficiency, cost reduction. also highlight significant CO2 reductions minimal impacts thermal comfort, showcasing substantial savings through targeted retrofits.
