Abstract In this paper, a transient analysis is performed in order to evaluate how effective climate data affect the determination of seasonal coefficient performance ASHPs. Three Italian cities, characterized by different climates, are considered as reference case studies and influence real meteorological data, collected from years, on heat pump SCOP performed. The carried out employing dynami...

Large-scale water pit thermal energy storage (PTES) promotes solar district heating (SDH) system as one of the most potential renewable applications for carbon neutrality. PTES needs vast investment and operates in a complicated with numerous components, highlighting need suitable simulation tool tech-economic feasibility investigations. This paper experimentally theoretically investigated long...

An improved optimization adjustment strategy for building heating ventilation and air conditioning (Heating Ventilation Air Conditioning, HVAC) is proposed. The energy consumption model of heating/refrigeration established by using the instantaneous balance heat, then optimal operation HVAC based on weather forecast data constructed in range user temperature comfort. Finally, MATLAB TRNSYS simu...

Heating ventilating air-conditioning (HVAC) systems have been increasingly widespread in Italy: they can exploit renewable energies, are energy efficient systems, do not directly consume fossil fuels, and the post-pandemic era, also subject to incentive processes by Italian government. In South Tyrol, harsh climates both winter summer seasons, ground-source heat pump (GSHP) be an excellent solu...

Falling-film drain water heat recovery (DWHR) systems are exchangers utilized in residential buildings for recovering energy from greywater. A recent publication by the authors contained a validated model that can be used to predict performance of DWHR under variable flowrates and temperatures, this work shows implementation into Transient System Simulation Tool (TRNSYS) software perform simula...

This paper presents the development of a computational model latent thermal energy storage (LTES) in shell and tube configuration with longitudinal fins. The describes physical process transient heat transfer between fluid (HTF) phase change material (PCM) LTES. For modeling PCM, enthalpy formulation was used. Based on one-dimensional model, new Trnsys type developed written Fortran. Validation...
