Solar heat collector - using carbon di:oxide as gaseous heat carrier medium

摘要

A solar heat collector for a gaseous heat carrier medium uses carbon dioxide by itself or in a mixt. with air. Carbon dioxide has the advantage that it achieves under solar radiation easily and quickly higher temps. than conventional media. The transparent material, of which the collectors are made, i.e. glass, quartz glass or plastics, plays only a subordinate part in the heat absorption process.
