Solar Heating and Cooling System with Absorption Chiller and Latent Heat Storage – A Research Project Summary☆

摘要: A reliable solar thermal cooling and heating system with high fraction seasonal energy efficiency ratio (SEER) is preferable. By now, bulky sensible buffer tanks are used to improve the for purposes. During summertime when heat converted into useful cold by means of sorption chillers waste dissipation ambient critical factor. If a dry cooler installed performance machine suffers from water temperatures, especially on hot days. In contrast, wet tower causes expensive treatment, formation fog risk legionella bacterial growth. To overcome these problems latent storage based cheap salt hydrate has been developed support days, whereby constant low temperature ensured. Therefore need avoided neither make-up nor maintenance needed. The same serves as additional purposes allowing optimal yield due temperatures. Four pilot installations between 7 kW 90 nominal capacity were equipped storages 80 kWh 240 content. Annual in situ measurement data shows positive effect up 11.4. Furthermore simulation results under different climatic conditions indicate raising 64% compared solely re-cooling. Long-term test bench measuring concerning durability well new approach state charge detection presented well.
