Fault diagnosis and commissioning of an active solar heating system

An active solar heating system is a kind of sustainable system with low energy cost and high efficiency, using renewable energy—solar. However, for most of solar heating projects, due to lack of the commissioning based on field measurement, there exist many problems, such as high energy consumption and poor thermal comfort, and even shutdown, which causes a serious waste of money and energy resource. Presents a case study on a solar heating system located in Tibet, and demonstrates the commissioning methodology for the solar heating system based on field measure data. Diagnoses both mechanical and control strategy issues. Verifies the improvement of system performance by comparing the operating parameters before and after system commissioning.
