Contribution to the Simulation and Parametric Analysis of the Operation of a Solar Concentration Thermal Installation

Abstract

The objective of this contribution is to highlight the direction of variation in thermal efficiency in order to determine the optimum thermodynamic parameters for the best operation of the solar concentrating heat machine. The machine studied as part of this article works in part following the ideal cycle of RANKINE and other part by following the ideal cycle of HIRN (improved installation). The preferred approach to achieve the objectives is based on: − Influence of low pressure and high pressure for a machine working according to the ideal RANKINE cycle. − And the temperature of overheating for installation next up the ideal cycle of HIRN. Simulations for different modifications on the RANKINE and HIRN cycles show that for an increase in the superheat temperature, the increase of the high pressure and the reduction of the low-pressure lead to a better yield. This contribution consists, from the simulations, to make a parametric analysis of the operation of an installation in order to propose a possible improvement.

An Extensive Design Approach Integrating Offshore Residential Buildings and Solar Collectors

“…Besides the practical functions, architects of modern residences pay more and more attention to the expression of the internal space to create an external shape with concavity and convexity [10]. In this case, such components as balconies, bay windows, and outdoor AC unit spaces become active elements, playing a key role in diversifying the building faç ade and creating nuances of gradations.…”

Simulation Study of Parabolic Trough Solar Power Plants in Brazil

“…Luo et al [16] developed a modified model to do a parametric analysis of the operation of a Solar Concentration installation in order to propose a possible improvement. Several review papers have been reported in the literature focusing on experimental and numerical investigations with parabolic trough power plants around the World [17][18][19][20][21][22][23][24][25].…”

Analysis Based on Intelligent Model about Intelligent Integrated Design of Additional Building Components and Solar Heat Collection Facilities for Offshore Residences

“…In response to these problems, the government began to adopt policies and corresponding technical regulations, and designers and real estate developers gradually launched the engineering operation. Hence, the initial idea of integrating solar water heaters with buildings was conceived, leading to the development of intelligent integrated design advancing to its second phase, known as the stage of basic overlay [6].Later, through consultations with solar developers, real estate developers began designing solar products with a modular mechanism [7]. As a result, solar water heaters have overcome technical and structural problems and could be perfectly integrated into buildings.…”
