The Workshop was visited by around 70 participants and provided an overview of the current status and latest developments in technologies for solar cooling in tropical climates as well as a guided tour of the world´s largest solar cooling system. Organisers were Solid, the International Energy Agency (IEA), Nanyang Technological University (NTU) and the Austrian Embassy in Singapore. Main topics focus was on Absorption chilling and Desiccant technologies.
In the morning the event, which was mainly organized by Patrick Soo, general manager of Solid Asia, started with a guided tour of the solar thermal cooling plant at UWCSEA East Campus in Tampines. The participants were split into two groups and each were shown the major collector field with cooling towers and expansion vessels, the heat storages, domestic hot water room and the heart of the cooling plant, the chiller room in the basement of the school building.
After the plant tour at United World College (UWC), the group had a bus transfer to Cleantech One in the Western part of Singapore. Cleantech One is a centre of research and development in the vicinity of NTU. It is managed by JTC and sponsored by EDB, the Economic Development Board of Singapore.
At Cleantech One, the workshop started with welcoming words of Volker Ammann, head of mission at the Austrian embassy who also showed a video about achievements of Austrian companies worldwide. Afterwards the solar cooling plants of Solid in Singapore, Abu Dhabi, Portugal, Jamaica and United States were presented by Moritz Schubert. In March 2013, the cooling plant at UWC Singapore reached a record cold production of 103 MWh of cold per month. Maximum electrical COP of the plant so far was 14. Even further potential for rise in efficiency was identified to be speed control of heat rejection.
Further presenters on solar cooling technologies and research works were from the Nanyang Technological University, Seris, the International Energy Agency, the Fraunhofer Institut, ZAE Bayern and DEIM at University of Palermo.
Visitors were mainly from research institutes, public authorities and professionals of the building and energy sector. It was very much appreciated by the participants that this workshop offered a plenum for different researchers and stakeholders in the Singaporean HVAC and building sector.
