1. Abstract This paper presents two approaches developed at the Australian National University for modelling the transient response of a parabolic dish steam cavity receiver. Both approaches are based on a heat transfer model for a cylindrical pipe using a moving-boundary formulation, and feature the ability to model multiple phase flow that changes dynamically. A model simulation is implemente...

Conventional basin-type solar still (CSS) is the simplest type of water distillation system. In this study, CSS was modeled and simulated. The effect variations in mass inside basin, absorber absorptivity, glass reflectivity heat loss coefficient were investigated. Finally, system simulated using same data radiation intensity, ambient temperature wind speed each variation highest distilled resu...

The impact of shade on the heating, ventilation, and air conditioning (HVAC) energy consumption in buildings is not automatically included in whole building energy simulations. Using transient system simulation (TRNSYS) software, models of the Union County Housing Authority’s energy efficient duplex enable the calculation of a monetary value for shading from trees, adjacent buildings, or shade ...

In the recent times, the use of solar energy for the refrigeration purpose has been increasing day by day. Generally, solar used for cooling purpose has proposed many advantageous features in the refrigeration field. The cooling path is basically depends on the amount of solar radiation. The more amount of solar radiation directly increases the C.O.P. of the system. In this research paper, the ...

This data article presents files supporting calculation for urban heat island (UHI) inclusion in building performance simulation (BPS). Methodology is used in the research article "From urban climate to energy consumption. Enhancing building performance simulation by including the urban heat island effect" (Palme et al., 2017) [1]. In this research, a Geographical Information System (GIS) study...

Recently builders have shown considerable interest in combining the features of active and passive solar space heating systems into a hybrid system employing active collection and some form of passive discharge/storage device. Ye examined the performance and economics of a hybrid2 air-based, residential system using 18.5 m of roof-mounted air collectors and a hollow-core slab that discharges di...

Heuristic rule-based control (RBC) is widely used in the building industry for building automation systems (BASs). Recently, researchers demonstrated that model-based control has the potential to improve the building energy efficiency. Model Predictive Control (MPC) is one of the promising approaches that caught much attention of the research community. The system dynamics model play an importa...

In order to solve the problem of input fresh air overheating (cooling) in cold supply (heating) season severe regions, a soil source (BHE) combined with preheating conditioning system was studied net-zero energy building Shenyang. Firstly, hybrid TRNSYS-CFD simulation model based on TRNSYS and Fluent software established simulate operation indoor temperature distribution during typical day summ...
