U.S. patent application 2015028556 (applicant Flamco BV, Netherlands):
"The present invention relates to a core of a capsule, capsules having the cores comprising phase changing material (PCM) to be processed to be form retaining in particular during subsequent steps of applying a skin to form the capsule, as well as an assembly of a plurality of such capsules, use thereof in a buffer, and a production method for manufacturing such capsules or assemblies, for instance in strings. ...
"The invention is based on the insight that the buffers in heating systems or heat exchange systems, like central heating systems, are usually filled with heat exchange fluids, like water. However, water and other usual heat exchange fluids have a limited heat capacity. According to the inventors of the present invention, it has been reported that phase change materials could be employed to enhance the heat capacity of a buffer, but to date no viable embodiment has been encountered."
