Influence of rainfall on the thermal and energy performance of a low rise building in diverse locations of the hot humid tropics
Rainfall is seldom addressed in the analysis of climates for building design, usually neglected for building thermal performance calculations, and there is very little research about its potential cooling effect.
This report presents a summary of the findings and activities of Stage 3 of the LCL-CRC research project RP 1033 “High Performance Commercial Building HVAC”.
The influence of design and everyday practices on individual heating and cooling behaviour in residential homes
Emerging results from practice-based research demonstrate that energy efficient houses often do not meet theoretical energy use based on the current standards of residential buildings. A factor influencing this inconsistency is related to user behaviour and everyday practices. The objective of this research is to...
Overheating of cities is causing serious energy, environmental and health problems and it has a serious impact on the whole economic and cultural life of cities. To counterbalance the impact of high urban temperatures several mitigation technologies have been proposed, developed and implemented. Monitoring of...
A comprehensive, multi-objective optimization of solar-powered absorption chiller systems for air-conditioning applications
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...
Solar-assisted absorption air-conditioning systems in buildings: control strategies and operational modes
Solar-assisted cooling technology has enormous potential for air-conditioning applications since both solar energy supply and cooling energy demand are well correlated. Unfortunately, market uptake of solar cooling technologies has been slow due to the high capital cost and limited design/operational experience. In the present work...
A systematic parametric study and feasibility assessment of solar-assisted single-effect, double-effect, and triple-effect absorption chillers for heating and cooling applications
The present work investigates the feasibility of solar heating and cooling (SHC) absorption systems based on combining three types of LiBr-H2O absorption chillers (single-, double-, and triple-effect) with common solar thermal collectors available on the market. A single-effect chiller is coupled with evacuated tube collectors...
Transient simulation and parametric study of solar-assisted heating and cooling absorption systems: an energetic, economic and environmental (3E) assessment
This paper presents energetic, economic, and environmental (3E) analyses of four configurations of solar heating and cooling (SHC) systems based on coupling evacuated tube collectors with a single-effect LiBre-H2O absorption chiller. In the first configuration (SHC1), a gas-fired heater is used as the back-up system...
Thermal–economic–environmental analysis and multi-objective optimization of an ice thermal energy storage system for gas turbine cycle inlet air cooling
In this study, a mathematical model of an ice thermal energy storage (ITES) system for gas turbine cycle inlet air cooling is developed and thermal, economic, and environmental (emissions cost) analyses have been applied to the model. While taking into account conflicting thermodynamic and economic...
