Solar Thermal Systems And Collectors
Heat pipe collectors A heat pipe evacuated tube collector uses alcohol or water in a vacuum which is used to absorb the sun’s energy. Due to the vacuum, the alcohol or water will evaporate at a low temperature of 25 C to form a vapour. This vapour then rises up the collector tube to the heat exchanger where heat transfer to the solar fluid ... Fetch Content
