Chiller staging is considered to be the reasonable and practical solution to the cooling energy saving. In this study, the part load ratio and the operating characteristics of vapour compression chiller were analysed within an office building. Moreover, the energy consumption among different chiller staging schemes was comparatively analysed. As a result, significant portions of total operating hours, cooling load and energy consumption turned out to be in the part load ratio range of 0 through 50% and thus the energy consumption was significantly affected by the chiller COP at low part load conditions. In addition, applying the sequential control chiller staging during the intermediate season and the uniform control chiller staging algorithm during the cooling season is considered to be the optimal control algorithm for maximized operational efficiency of chillers. |
