Solar desiccant air-conditioning is an emerging technology that offers the promise of reducing reliance on grid connected electricity for providing comfort air-conditioning. Development of a method of assessing the seasonal energy savings of these devices would enable a fair comparison with alternative devices. This could be used in policy support mechanisms to assist industry growth.
Solar heating and cooling (SHC) systems are currently under rapid development and deployment due to their potential to reduce the use of fossil fuel resources and to alleviate greenhouse gas emissions in the building sector – a sector which is responsible for ~40% of the world energy use.
This book focuses on the challenge that Australia faces in transitioning to renewable energy and regenerating its cities via a transformation of its built environment. It identifies innovative and effective pathways for decarbonising the built environment from applied research undertaken by the Co-Operative Research Centre for Low Carbon Living.
This project used the insights gleaned from CRCLCL Program 3 social research projects, particularly RP3029, to develop a web-based platform to support a transition to a low carbon and energy efficient residential housing sector.
High-temperature absorption chillers (double-effect and triple-effect) have a higher coefficient of performance (COP) than single-effect chillers. This can reduce the collector’s footprint and cost in a solar-cooling plant.
The feasibility of solar-powered multi-effect LiBr-H2O absorption chillers is investigated under different climate conditions, and three configurations of solar absorption chillers are proposed with respect to the type of the chiller.
Solar heating and cooling (SHC) systems are currently under rapid development and deployment due to their potential to reduce fossil fuel use and to alleviate greenhouse gas emissions in the building sector – a sector which is responsible for ∼40% of the world energy use.
In this paper, a detailed simulation model of a solar-powered triple-effect LiBr–H2O absorption chiller is developed to supply both cooling and heating demand of a large-scale building, aiming to reduce the fossil fuel consumption and greenhouse gas emissions in building sector. TRNSYS 17 is used to simulate the performance of the system over a typical year.
This paper explores the potential for solar thermal cooling to succeed commercially, and more specifically, the application scenarios where this is most likely. This mainly philosophical contribution hopes to highlight directions for future research.
