VAPOUR ONLY CYCLING OF HEAT TRANSFER FLUID FOR THE THERMAL STORAGE OF SOLAR ENERGY

摘要

Heat transfer fluid in vapour only state is cycled through solar collector(s) (12) and a sensible heat storage medium (14) to transfer heat from the solar collector(s) (12) to the sensible heat storage medium (14). The heat transfer fluid is a liquid at ambient temperature, but substantially in the vapour state throughout the entire cycle when in operation.
