摘要
Abstract
The energy consumption and application field of energy cascade utilization technique of chilled water were analyzed based on the objective function of refrigerating capacity by unit mass. The result shows that, comparing with chillers under the conventional 7℃/12℃working condition, the proposed technology is able to reduce the power consumptions of both chillers and chilled water pumps. When the temperature difference is increased from 6℃ to 11 ℃, the total power consumption is reduced in a range of 0.77% to 2.26%. The large temperature difference air-conditioning chilled water system applies for pumping head larger than 31.7 meters and chilled water supply and return water temperature difference smaller than 9.2℃, however, the new technology doesn't have these limits, and it can save energy at any pumping head.关键词
