IEA SHC: Free Pre-Sizing Tool for Solar Heating and Cooling

Submitted by Baerbel Epp on July 14, 2017
PistacheIn 2015, Task 48 – Quality Assurance & Support Measures for Solar Cooling – came to an end. One of the activities of this IEA Solar Heating & Cooling Programme task was the creation of PISTACHE, a tool for professionals who need to pre-size solar cooling, heating and domestic hot water installations and assess their estimated performance. As part of the Habisol programme, the development of the tool by French organisations Tecsol and INES during the MeGaPICS project received additional funding from the French National Research Agency. It is available as a free download in English and French on the website of Task 48.
 

India: Honeywell Successfully Showcases Solar Cooling Project

Submitted by Baerbel Epp on June 9, 2017
HoneywellTypically, lighting and air conditioning account for more than half of overall electricity consumption in India’s industrial offices. As applications in industry have been hit with the highest tariff of all power consumers, it will need new solutions to reduce the electricity demand of conventional AC systems. To this end, Honeywell Technology Solutions based in Hyderabad in the southern state of Telangana has been operating a pilot project for solar thermal cooling since March 2013. The lithium-bromide chiller is connected to 128 parabolic trough collectors, each with a reflector area of 6.41 m², and provides air cooling at temperatures between 21 °C and 23 °C for six months a year. The collectors were delivered by the solar energy division of Indian manufacturer Thermax.

Italy: New Solar Cooling Systems and Opportunities

Submitted by Baerbel Epp on June 7, 2017
MayaGovernment incentives have been pushing solar cooling forwards in Italy. The large budget available for national incentive scheme Conto Termico 2.0 has made several service providers optimistic about the future of the Italian market. For example, Mario Colaiemma from Maya, the European distributor of Japanese Yazaki chillers, said that “Italy was the key market for our solar thermal-driven chillers in 2016.” The photo shows a typical solar cooling system based on slightly below 50 m² of vacuum tube collectors connected to a 17.6 kW chiller. It was installed in Sicily, also home to two solar cooling plants by German chiller manufacturer Fahrenheit (formerly Sortech). Gregor Feig, Head of Sales at Fahrenheit, said in March 2017 that “two sorption cooling systems were put into operation in data centres in Enna and Caltanissetta, in the very sunny region of Sicily. Two more systems have been delivered, but haven’t gone online yet.”

YazakiTwo larger solar thermal cooling installations were put into operation in China in 2016. One of them was a 23-kW Yazaki absorption system (left photo) and one a new developed 50-kW variable-effect absorption chiller driven by a Fresnel collector (right). Solarthermalworld.org spoke with Professor Yanjun Dai of Shanghai Jiao Tong University (SJTU) about the market and technological advances of solar cooling in China.

China: Solar Process Heat and Space Heating and Cooling Rack Up Market Shares

Submitted by Baerbel Epp on April 19, 2017
CSTIFChina’s shift away from residential towards commercial solar thermal applications continues: The collector area of newly installed solar water heaters in single-family buildings declined by 26 % in 2016, whereas the ‘engineering segment’ remained stable last year (see the table below). This segment is comprised of all non-domestic hot water applications, such as space heating and cooling as well as applications in industry and agriculture. Overall, its share in the newly installed collector area went from 61 to 68 %. All figures were taken from the Report on the State of China's Solar Thermal Industry (July to December 2016), a document drafted by Dezhou-based consultancy Sun’s Vision on behalf of CSTIF, the Chinese Solar Thermal Industry Federation. CSTIF has presented this report – which also includes several development strategies – to the National Energy Board. 
 

Jordan: Four Demonstration Plants for Solar Air Conditioning Commissioned

Submitted by Baerbel Epp on March 29, 2017
Petra Guest House JordanJordan is showing rapidly increasing demand for air-conditioning. Total annual emissions from cooling commercial buildings add up to 600,000 tonnes of CO2, an amount equal to emissions from about 120,000 passenger vehicles per year. This has prompted the German Agency for International Cooperation to initiate the project Solar Cooling in Industry and Commerce in Jordan. The German Technische Universität Berlin (TUB) played a key role in this transfer of technology and know-how for the planning and installation as well as monitoring of four solar-driven air-conditioning systems in public and private buildings. The photo shows the 388 m² collector field which was commissioned at Petra Guest House in February 2015, around the same time as the one at German Jordanian University.

SolarCool Europe: Solar Heat Reduces Chiller Electricity Consumption

Submitted by Baerbel Epp on July 27, 2016
SolarCool InstallationIn April 2016, British company SolarCool Energy put into operation its largest SolarCool system, which was installed on the roof of Chingford Fruit’s processing plant (see photo) in Dartford Kent, UK. Fifty-four retrofitted vacuum tube collectors totalling 160 m² have since reduced the power consumption of the existing compression chillers with a cooling capacity of 1 MW. According to Central Services Manager Colin Ormerod, Chingford Fruit has saved 100,000 kWh of electricity during process cooling (16 °C) over the two full months that the system has been in operation (May and June). The SolarCool technology was developed in 2009 in the USA, and reached European markets in 2013/2014. In the meantime, there have been around 6,000 systems set up across all continents – the majority in Latin America, Caribbean and South East Asia, according to Dr Kurt Orthmann, Joint Managing Director at SolarCool’s European subsidiary, SolarCool Europe.

IEA SHC Programme Scales up its International Research Network

Submitted by Baerbel Epp on May 18, 2016
The IEA Solar Heating and Cooling Programme (IEA SHC) broadens its sponsor network. The most recent members are the International Solar Energy Society (ISES), headquartered in Germany, and the Gulf Organisation for Research & Development (GORD) based in Qatar. ISES joined as a Sponsor in 2016 and GORD already in 2015. “We welcome the engagement of ISES and GORD in the IEA SHC Programme,“ says Ken Guthrie, Chairman of IEA SHC. “ISES represents an extensive network of solar thermal professionals from around the world and GORD opens the doors to the Gulf States – potential future markets for solar cooling“. 
 

IEA SHC: Industry Workshop in Spain Shows Solar Cooling’s Global Opportunities

Submitted by Baerbel Epp on April 30, 2016
Task 43 WorkshopThe latest R&D developments in solar cooling presented during a workshop in Madrid, Spain, on 11 April sparked great interest among the attendees from the international air conditioning industry. Held at the headquarters of the Spanish Institute for Energy Diversification and Saving, IDEA, the event brought together representatives from companies, such as Baxi Roca, Carrier, Fujitsu, Kaysun and Panasonic, as well as researchers from Task 53, New Generation Solar Cooling and Heating Systems, of the IEA Solar Heating and Cooling Programme. The presentations showcased innovative solutions driven by solar heat or solar power. The experts agreed that solar cooling will be a market for both solar thermal and solar PV solutions over the coming years and will capture new territory outside Europe, such as in the Middle East or China. A current study on the Arab region concluded: PV cooling technologies are more economical than grid-driven electric chillers at cooling loads of 100 kWc, whereas solar thermal cooling should be used for 1 MWc cooling.
