This presentation - given by ESTTP’s Dr. Wim van Helden at the 2012 Renewable District Heating and Cooling Conference - sets out key Research and Development priorities for the solar thermal industry in the next decade. Challenges still remain to reduce investment costs, further increase solar fraction and further develop solar thermal technology.
As part of a series of IEA Roadmaps on energy technologies, this report specifically maps the potential development of heating and cooling equipment for energy-efficient buildings between 2011 and 2050. In line with other roadmaps, two scenarios are plotted: a baseline scenario representing minimal policy change and a BLUE map scenario with aggressive policy action.
This case study was written by SunWater Solar. It discusses their solar thermal cooling installation project that they completed on the Solar Decathlon House at Santa Clara University in California.
Three collectors were installed which are connected to an absorption chiller which creates the cold water for the air conditioning system. This project is a demonstration installation and was a collaboration between the Santa Clara University School of Engineering and SunWater Solar. The system should offset approximately 4 barrels of oil usage every year.
This case study was written by Gemco Solar. It profiles a solar thermal water heating and air cooling and heating system they installed on the Shouldice Hospital in Thornhill, Ontario, Canada.
Displacing a natural gas and electric based system, Gemco installed 131 solar thermal collectors and 10 solar thermal cooling machines on the hospital. The systems account for roughly 55% of the hospital’s total energy use. Each year, the system is project to displace over 100 metric tons of CO2 emissions that the hospital would have otherwise created with their previous system.
This report was written by Alexander Holiday and Yin Yaling of the University of Minnesota. It reports on simulation trials of solar thermal air condition systems that were run on a modeling software program.
The system in question was a solar thermal ceiling cooling system. The model showed that when air inflow temperature was increased, humidity rose, and the comfort level of the room was decreased. However, the researchers gained a positive result when increasing the ceiling cooling temperature, which dropped the humidity, and increased the comfort level of the room.
This presentation was created by the solar energy company Ontility. It covers solar thermal technology, applications, and the basics of the science that make solar thermal possible.
This presentation was created by the SOLID Group. It discusses some solar thermal applications such as process heat and solar cooling, and provides case studies and photos to illustrate the benefits of these solar thermal applications.
This white paper was written by William Guiney of Johnson Controls. It looks at the opportunities and potential for long-run development and wide spread use of solar thermal, especially for pool heating, space heating, and cooling applications.
