摘要：According to a ward office building air conditioning system historical operation data, this article analyzed the number of air-conditioning cooling load operation, the time frequency and air conditioning systems circulating water temperature difference trend with air-conditioning load; proposed 4:2:4 group control method to the modular water chillers and air-conditioning water system energy-saving control scheme of variable frequency plus constant temperature difference. Energy-saving control system using Programmable Logic Controller (PLC) as the core controlling device was built, control logic was programmed. The running experiments show a remarkable energy-saving rate of 26.1%, with good energy efficiency and economy effects. ? 2010 IEEE.
