India: Innovative Solar Cooling System at Solar Energy Centre

Submitted by Baerbel Epp on August 10, 2011

 Solar air conditioning demonstration system” The Solar Energy Centre in Haryana State can now score with a new and innovative solar air conditioning demonstration system: Developed by Thermax, one of India’s leading waste heat recovery and cooling manufacturers, the system with a 100 kW cooling capacity has an integrated triple-effect Vapour Absorption Chiller (VAC) and solar parabolic concentrators. Both components were developed locally through a 15-month cooperative application research by the Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), the Indian Institute of Technology Kanpur (IITK) - both from India -, and the German ISE Fraunhofer Institute.

CERN’s Ultra High Vacuum Flat Plate Solar Collector Markets and Applications (2008)

Submitted by Raquel Ponte Costa on August 4, 2011

This is a presentation from the CERN (European Organisation for Nuclear Research) about solar thermal technologies and applications.

The presentation reviews the different market applications (hot water and heating, space heating and cooling, desalination, pool heating, industrial processes and electricity production). It also gives data on the European energy market and the market share of the different solar technologies. The document indicates the market drivers for solar thermal and the forecasts for the coming years.

 

Solar Cooling. A Review of Technology, and Feasibility Study for Ager Sectus Winery, Blenhein, New Zealand (2010)

Submitted by Raquel Ponte Costa on July 21, 2011

This document reports the results of a study undertaken at the Ager Sectus Winery, near Blenheim, in New Zealand. The study looked at different solar cooling technologies and their possible use in the winery.

The document starts by explaining the different solar cooling technologies (PV, heat engine, absorption chiller, etc). Solar thermal absorption cooling is the most popular air-conditioning application and is used in different parts of the world. The performance of the systems is still variable, but the average payback period is of 15-20 years.

Solar Cooling Market to experience big Changes

Submitted by Baerbel Epp on July 18, 2011

 Uli Jakob” According to Dr Uli Jakob, Vice President of the “Green Chiller - Association for Sorption Cooling”, the solar cooling sector may soon experience a shift from small series production of a niche market to considerable manufacturing quantities. Jakob points out two signs supporting such a development: First, the approval of the IEA-SHC task 48, “Quality Assurance and Support Measures for Solar Cooling“; second, the recent market entry of big players, such as Stiebel Eltron (Germany) and Hitachi (Japan).

Cyprus: 4th International Solar Air-Conditioning Conference in Lanarca

Submitted by Baerbel Epp on May 16, 2011

 Solar Cooling Installation” Following Bad Staffelstein (Germany, 2005), Terragona (Spain, 2007), and Palermo (Italy, 2009), the 4th International Solar Air Conditioning Conference will now take place in Lanarca, Cyprus, from 12 to 14 October 2011. Over the years, the conference has grown into an important event, at which scientists and industrial researchers, product manufacturers, building designers and planners, contractors, and installers have met to exchange knowledge and experiences. The complete conference schedule is now available for download - and also attached to this news piece.

The Effects of Passive Heating and Cooling on the Energy Performance of Buildings – CEN Calculation Procedures (2009)

Submitted by Raquel Ponte Costa on May 13, 2011

This is a document providing an overview on passive heating and cooling technologies and their impact on the energy performance of buildings presented by Anna Staudt and Hans Erhorn from the Fraunhofer Institute for Building Physics concerning the CENSE project in Germany, with the funding from the EU’s Intelligent Energy Europe programme.

Solar Concentrator (2010)

Submitted by Raquel Ponte Costa on April 29, 2011

This is a brochure made by a Bulgarian company Bulgaria Therm about a solar concentrator which can be used for heating and cooling in a winter, such as in a summer period.

A comparison between this product and a solar collector is provided by graphics and schemes. Functional and technical characteristics are detailed and visually presented and the utility of its use in systems of cooling and heating are presented with a better ratio of efficiency than a solar collector. This solar concentrator can be linked to an energy network or to a private house.

Australia: Economics of Solar Thermal, PV-based and Conventional Cooling System (2010)

Submitted by Baerbel Epp on April 20, 2011

 Lifetime Costs” In Australia, solar cooling is still a niche technology - despite good solar resources and a large air-conditioning and refrigeration market. The multiple market barriers which prevent the technology from achieving greater market shares are mostly economic in nature. During a presentation at the 9th IIR Gustav Lorentzen Conference 2010 in Sydney, Dr Paul Kohlenbach, Director of international solar cooling consultancy Solem Consulting, and Dr Mike Dennis of the Australian National University, highlighted these market barriers and opportunities for solar cooling in Australia. Kohlenbach himself has additionally carried out a study comparing the economics of a solar thermal, a PV-based and a conventional cooling system over a 20-year lifespan.

Solar Cooling: German Fraunhofer ISE compares PV and Solar Thermal

Submitted by Baerbel Epp on February 14, 2011

 Saved primary energy and difference in total annual cost ” Over the last 5 years, the number of installed solar cooling systems worldwide increased tenfold. The main obstacles for a more pervasive and faster market development are high upfront costs and lack of experience among main stakeholders, such as planners and architects. Based on various simulations, German institute Fraunhofer ISE analysed the saved primary energy and total annual costs of solar thermal, photovoltaic and conventional solutions for heating and cooling by using the example of a hotel in Madrid (see attached presentation).

Solar Heating and Cooling of Buildings (2007)

Submitted by Raquel Ponte Costa on February 3, 2011

This document includes detailed information about solar heating and cooling technologies for buildings. The document is one of the deliverables of the BRITA in PuBs project (Bringing Retrofit Innovation to Application in Public Buildings). This FP6 funded project involves different countries (Norway, Denmark, Italy, Greece, Germany, UK, Lithuania and Czech Republic). The aim is to develop demonstration projects in selected public buildings to demonstrate how renewable energies could be used.
