Jordan 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.
All smiles from Ritter Group management during the German Solar Thermal Technology Symposium at the beginning of May after they were given the innovation award for the demonstration plant of a steam-producing solar vacuum tube collector combined with a steam-jet chiller (from left): Thomas Weidemann, Division Manager Solar Collectors, Jürgen Korff, Chairman of Ritter Group management, and Dr Rolf Meißner, Managing Director of Ritter XL Solar. Ritter is a German manufacturer of CPC vacuum tube collectors. Five companies – among them Viessmann, Vaillant and Magontec – had applied for the award with a total of seven innovative technologies. The award is presented annually by the conference’s organiser, the East-Bavarian Institute for Technology Transfer, OTTI.
The Solar Keymark certification is getting more consumer-friendly: Since the beginning of this year, the new certificate data sheets include a second page on the annual collector unit output for different solar radiation sites in Europe (Stockholm, Davos, Würzburg and Athens). The list shows the output at average collector temperatures of 25, 50 and 75 °C. For example: The new optimised Aqua Plasma collector 19/17 by German collector producer Ritter achieves 1,106 kWh per collector unit and year in Würzburg (50 °C). The gas-filled flat plate collector PS1-52 Joule by Austrian company Geo-Tec achieves 793 kWh at the same location. Both collectors were launched this year with a gross collector area of 1.69 m² and were presented at the Intersolar Europe in June. The listed output should now give end consumers a good hint at what they get for their money.
The German Ritter Group is proving its commitment to eco-business more and more: The latest generation of the Paradigma double-glass evacuated tube collectors, called Aqua Plasma, shows improved performance, as well as a reduction in weight and carbon emissions. This development matches the company’s philosophy, which has characterised Ritter since its origins and has lately received the name “Ecoquent” (Ecological Consequence).

At the beginning of July, Shandong Linuo Paradigma Co. Ltd celebrated ten “golden years” of a successful Chinese-German partnership between the Chinese corporation and the German Ritter Group.

After the Group's new vacuum tube titanium coating has proven itself on the Chinese market for the past year, Linuo Solar Thermal is thinking about introducing the product also on international markets. One of the biggest manufacturers of vacuum tubes in China has so far used an aluminium-based coating for all its products. The new coating of the Sunrain group - presented at the company´s 10-year anniversary in December 2010 – is said to be based on titanium as well. Photo: Linuo Group
