The increasing demand for refrigeration and air conditioning has led to a dramatic increase in peak electricity demand in many countries. With the increase in demand comes the increase in the cost of electricity and summer brownouts, which have been attributed to the large number of conventional air conditioning systems running on electricity. As the number of traditional vapor compression cooling machines grows (more than 100 million units sold in 2014) so do greenhouse gas emissions, both from direct leakage of high GWP refrigerant, such as HFCs, and from indirect emissions related to fossil fuel derived electricity consumption. An obvious counter to this trend is to use the same energy for generation of cooling that contributes to creating the cooling demand—solar energy.

A tremendous increase in the market for air-conditioning can be observed worldwide especially in developing countries. The results of the past IEA SHC Tasks and work on solar cooling in SHC Task 38: Solar Air-Conditioning and Refrigeration show the large potential of this technology for building air-conditioning, particularly in sunny regions. However, solar thermal cooling faces barriers to emerge as an economically competitive solution. Thus there is a strong need to stimulate the solar cooling sector for small and medium sized systems.

The September workshop on New Generation Solar Cooling & Heating Systems focused on the status of solar cooling technology research and market developments. About 40 professionals gathered in Rome for this half day event, which was organized by IEA SHC Task 53: New Generation Solar Cooling & Heating Systems and the German Eastbavarian Institute for Technology Transfer, OTTI e.V. the day before OTTI’s 6th International Conference on Solar Air-Conditioning. Participants learned first hand about the first outcomes of SHC Task 53 that began its collaborative work in March 2014 and includes the participation of ten countries from across the globe.

The results of past IEA SHC Task 38 Solar Air-Conditioning and Refrigeration and ongoing IEA SHC Task 48 Quality Assurance and support Measures for Solar Cooling systems on the one hand showed the great potential of this technology for building air-conditioning, particularly in sunny regions. On the other hand, it has been shown that further work is necessary in order to achieve economically competitive systems, using either the solar thermal or the solar photovoltaic driving energy. One Task definition workshop has been held with the aim to define the required new activities and to develop a structure for a new Task entitled „ PV and solar thermal driven cooling & heating systems “. Stimulated by the rising cooling demand in the World and at the same time a very significant PV modules price decrease, an important interest for new generation solar cooling systems has arisen. At the same time, solar thermal cooling technology still suffers from an important lack of competitiveness due to a very small market size and difficulties to go to massive cost reduction at least in the small system (<50 kWcooling) range. Besides, the solar photovoltaic source coupled with compression technology (heat pump) presents a very promising alternative but is still in its technical infancy.
