Heat Storage, Air Heating, Certification

  • Online database on advanced PCMs

    Compared to water, phase change materials (PCMs) offer more capacity to store heat in tanks. As a consequence, researchers in all corners of the world have been developing new materials and their properties. To ensure the employment of a shared methodology and the use of equivalent terms to...

  • “Excellent material for sorption-based solar energy storage”

    Microporous hydrophilic substances such as zeolites are recognised as promising materials for very efficient energy storage. Solar thermal systems are used to dry the material and store all of the thermal energy inside without losses until water is returned into the structure to release...

  • Solar air heating and cooling system with four new components

    New Zealand-based Sojol has designed a prototype of a solar air heating and cooling system which consists of a glazed solar air collector, a heat exchanger and a newly developed helical fan and delivers air at a desired temperature and an optimised flow rate and pressure level.

    Concrete slabs store thermal energy and heat homes

    Many building owners consider roof-integrated solar systems to be a tried-and-true way of saving as much on their heating bills as they can. A research project called solSPONGEhigh and developed in Austria has shown: When using thermal mass, i.e., the capacity of a building to store heat in...

    EU labelling: “Solar devices to be classified as heaters”

    The German-based Solar Heating Initiative has developed a new calculation method to label solar thermal systems based on the Ecodesign Directive 2005/32/EC. It put the method, which allows for a fair assessment of solar thermal energy input into a heating system, forward for consideration...

    Three labels in Europe – what are the differences?

    Labels and trademarks should give the end-consumer a clear feedback on the quality and performance of the labelled product. Currently there are three labels available for solar products or solar assisted heating systems in Europe, so there is an increasing need to explain the differences to...

    On-site collector testing: new standard in development

    Once a large solar field is set up at its designated location, what tests can be conducted to show that it performs as expected? Soon, the IEA Solar Heating & Cooling Programme may have an answer to this question, as it is working on internationalising Denmark’s testing procedure. No...
