This paper describes a dynamic model of a steam cavity receiver and presents results from simulations performed using this model in TRNSYS 16. The results are compared with experimental data to inform the calibration of specific model parameters. Using the experimental data obtained from the SG4 500 m2 dish at the ANU, it is possible to select a set of model parameters that produce good agreeme...

Controlling borehole dynamic response and maximizing efficiency requires an accurate dynamic model to develop an efficient control strategy. Therefore, it is tested to what extent a simple linear model is able to predict the dynamic response of the mean fluid temperature in a single borehole to a given heat input. Three model types are proposed, which have been identified and evaluated through ...

In this paper, a thermal performance assessment of traditional building constructions and configurations in various Moroccan climates is carried out. This research focuses on enhancing conventional energy efficiency buildings by investigating the behavior single clay walls, double simple brick walls based long-term meteorological data using TRNSYS software. The roof pitch, comfort discomfort in...

Indoor temperature and relative humidity control in office buildings is crucial, which can affect thermal comfort, work efficiency, even health of the occupants. In China, fan coil units (FCUs) are widely used as air-conditioning equipment buildings. Currently, conventional FCU methods often ignore impact indoor on building occupants by focusing only a single object. This study FCUs with fresh-...

Abstract Concerns about building thermal performance and energy consumption are fast growing as they account for roughly 40% of worldwide annual use. Building construction in Nepal is controlled by the National Codes (NBC), which focus solely on structural considerations ignore behaviour. As a result, housing tends to be too much warm cold during summer winter respectively due lack passive heat...

This paper presents a feasibility and performance study of ground source heat pump (GSHP) coupled with horizontal exchanger (HGHX) used for cooling residential unit equipped radiant floor system (RFs) under the meteorological conditions Saharan environment in Ouargla, city located Southeast Algeria. A dynamic simulation is developed using TRNSYS software modeling GSHP system. To verify reliabil...

Data-driven models, either simplified or detailed, have been extensively used in the literature for energy assessment buildings and districts. However, uncertainty of estimated parameters, especially thermal masses resistance–capacitance (RC) still remains a significant challenge, given wide variety functionalities, typologies, structures geometries. Therefore, sensitivity analysis parameters R...
