In this paper, an office building in Beijing is taken as the research object. This collected the operation data of the air-conditioning water chiller on a typical summer day. The performance of the air-conditioning water chilling unit and system is tested. This evaluates energy efficiency according to national standards and puts forward optimization suggestions. The results show that under low-load operation, the performance coefficient of the chiller reaches the detection index, but the efficiency of the air conditioning system is low. It is recommended to reduce the number of corresponding air conditioning equipment to optimize the performance coefficient of the air conditioning system. And the chiller can be installed a frequency conversion device to improve the operating performance of the chiller.
