SOLAR HEATING ELEMENT AND SOLAR HEATING UNIT USED FOR COLD PRODUCTION

摘要

The invention concerns a solar heater element comprising at least one longitudinal body having one flat side and a second arched side which collects incoming sun rays to a focal line. The arched side of the element has an ellipsoidal outer surface to avoid aberration of light. It relates to the problem of directing incoming light to an exact focal line. A further aspect of the invention is to make use of the incoming light; to transfer the solar energy to a liquid thus heating it. The liquid is carried in a tube and is, in one aspect of the invention, connected to a cooling system. To put this into practice the heat carrying medium is pressurized with the assistance of a valve arrangement.
