Dear Colleagues,


With first installations more than a century back, triggered by the oil crisis, thermally driven cooling systems have been researched and demonstrated for more than forty years. Starting from rather fragile solutions with only limited energetic performance, over the years significant progress has been made in terms of reliability and efficiency. Yet, complexity and high first cost remained issues for further improvement.

When the cost for photovoltaic electric generation was reduced substantially within the last decade, a common understanding developed amongst experts that the electric version of solar-driven cooling would win the palm. Beyond all doubt, vapour compression cooling systems are capable of converting renewable electric power into useful cooling for an attractive price. Yet, since renewable energy generation covers a considerable share of the total supply, flexibility of generation and consumption gain increasing importance and storage capability becomes a dominating aspect for a secure and reliable energy system. According to this trend, solar thermal electric generation as an alternative to PV may regain higher importance due to its ability for decoupling solar gain and electric output by means of a thermal storage. The same holds for thermally driving cooling: Driving heat provided by solar thermal collectors can be buffered or cooling potential can be accumulated inside the thermodynamic cooling cycle for later use.

Apart from all technical arguments, currently heating and cooling in buildings and industry account for approximately 40% of final energy consumption. As stated in the current IEA’s World Energy Outlook, “rising incomes mean that many millions of households add electrical appliances… and install cooling systems. By 2040, electricity demand for cooling in China exceeds the total electricity demand of Japan today”.

It is obvious that all options have to be considered for the evolution of the energy supply. Solar thermal systems have to deliver both heating and cooling synergistically, and overall, a balance between electric and thermal solutions has to be found.

The 2018 Solar Air-conditioning Conference will be integrated in the frame of the EuroSun conference. Thus, a perfect opportunity is given for surveying current trends in solar cooling with electric or thermal input, and getting in touch with the full range of solar thermal development.

You are cordially invited to actively participate and contribute to the further development of renewable energy-driven cooling and air-conditioning. The SAC conference will comprise three or four technical sessions plus a poster session with short oral summaries of the poster contents. The programme of the conference will cover one or one and a half days, followed by a technical tour. This frame will allow to enjoy a rather compact survey of the current status of solar-driven air-conditioning or to step into other topics provided by the EuroSun conference, which runs for three days including the technical tours. According to your choice, different conference fee options will apply.

Join in the search for the future of solar cooling, join us in Rapperswil!
