The analysis and improvement of the humidity problem on air-condition system of SSRF

In this work, efforts were made to solve the problem of high relative humidity in some areas of the Shanghai Synchrotron Radiation Facility (SSRF). Based on data analysis, theoretical demonstration and field tests, we found that the problem of high humidity was caused by two factors. The high humidity problem was solved by appropriate measures of keeping the actual operation load match to the design load of the air-conditioning systems and minimizing the outdoor air infiltration.
