  • Energy and exergy analyses of a solar–driven absorption cooling system

    In this paper, energy and exergy analyses of an absorption cooling system using H2O/LiBr and solar energy as heat source are conducted. A simple schematic of a chiller and an improved one, are compared using Thermoptim and EES software. An increase in the coefficient of performance (COP) from 0.69 to 0.8 was noticed. Numerical simulations are performed for six values of the ...

  • Cooling loads analysis of an endoreversible solar absorption refrigerator cycle

    This paper deals with the analysis of the Cooling Loads (CL) of a solar absorption refrigerator. For this purpose, a new Process Conceptual Design (PCD) approach based on equivalent endoreversible model and hierarchical decomposition is developed. The influences of many cooling load aspects on the model performances are investigated. A sensitive study is made: performance coefficient (i.e. its ...

  • Heating and Cooling in the upcoming EU Renewables Directive

    It is crucial that the future EU Renewables Directive includes effective measures to promote renewable heating and cooling (RES-H). To reach the 20% target by 2020, almost half of the growth in renewables production has to come from RES-H alone. Heating is a primary human need. Supply shortage recently became a credible scenario. While reducing this risk, RES-H can achieve substantial cost ...

  • Design of passive cooling system for a building in composite climatic conditions in India

    A combined solar chimney?wind tower concept has been developed for a typical urban institution building in Delhi. Due to site limitations, the concept of solar chimney based ventilation has been introduced through roof mounted thermo-siphon air panels of 70 m? absorber area. A wind tower provided on the suction side of fresh air has potential for cooling incoming air by 5?C by using 250 m? of ...

  • Sustainable cooling solutions for application in Western Cape Province, South Africa

    The energy demand in building sectors for summer air–conditioning is growing exponentially due to global warming, increased living standards and occupant comfort demands throughout the last decades. Concerns over these environmental changes have begun shifting the emphasis from current cooling methods, to 'sustainable strategies' of achieving equally comfortable conditions in building interiors. ...

  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • Bright future of solar lighting

    Hybrid solar powered lighting (HSL) isn't anything like solar light based power that changes over daylight into power. Through the utilization of optical strands, HSL catches daylight, diverting it and funneling daylight into a building. At the point when there is practically no daylight, these installations use power with the goal that consistent lighting is accomplished. Gatherer ...

  • CPV solar power system

    There are relatively few CPV applications still pursuing Si cells. The idea was somewhat "hot", no pun intended, when there was a silicon shortage going on, but silicon prices have dropped as new capacity has come online and the only successful CPV concepts being marketed which I know of are based on triple junction Ge/GaAs/InGaP or similar cells. These are also rather heat sensitive, and the two ...

  • Effects of Solar Energy On Wildlife

    In America’s southwest, the high potential for harnessing the solar energy as a renewable source is exponentially large. In addition, in the southwest the numbers of endangered species of birds and mammals is also large. What will the impact be on these birds and animals, as renewable energy sources are operating? How can Solar Energy be ...

  • Solar Chimneys in Buildings - The State of the Art

    Improvement of the energy performance of buildings and achievement of indoor comfort conditions can be attained by passive cooling techniques and energy efficient measures. Natural ventilation is one of the simplest and most widely applied cooling strategies, achieved by permitting air to flow through the building. The solar chimney is a construction on the building's envelope that exploits solar ...

  • Solar Thermal Action Plan for Europe

     Ten years ago, the European Commission published its White Paper on Renewables, proposing a Community Strategy and Action Plan. Since then, European Directives to promote renewables in the electricity sector and in the transport sector have been successful in kicking off substantial growth in these two sectors. However, the renewable heating and cooling (RES-H) sector has been neglected at ...
