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.

主权项

1. A solar power station having:
a sensible heat storage medium; at least one solar collector; a heat transfer fluid that is liquid at ambient temperature; a heat exchanger for transfer of heat from the heat transfer fluid to the sensible heat storage, the station having a first mode of operation in which heat is transferred from the heat transfer fluid to the sensible heat storage and heat transfer fluid substantially in the vapour state is returned to the at least one solar collector.
