Method for operating solar thermal plant, involves circulating transmission medium in solar circuit by solar circuit pump, where transmission medium exchanges weather condition or seasonal condition

摘要

The method involves circulating a transmission medium in a solar circuit (10) by a solar circuit pump (13). The transmission medium exchanges weather condition or seasonal condition against another transmission medium. The transmission medium is provided for operation at high temperature and the latter transmission medium is provided for operation at low temperature.
