摘要
多联机系统在自由组合时,由于各室外机性能参数存在差异,如何根据室内需求负荷发挥各室外机最佳能效比是节能的关键。本文根据各室外机不同工况下能效比参数和室内负荷,对比切换前后能效比计算值,选择最佳室外机组合,确定各室外机的压缩机运行频率。通过试验测试数据对比分析,整个系统处在最佳能效比状态下可实现15%节能运行。
When the multi-connected air-conditioning(heat pump)unit is combined freely,due to the difference of performance parameters of each outdoor unit,how to play the best energy efficiency of each outdoor unit according to the indoor demand load is the key to energy-saving.According to the energy efficiency ratio parameters and the current indoor load of each outdoor unit under different working conditions,the energy efficiency ratio calculation values before and after switching are compared,the best combination of outdoor units is selected,and the operation frequency of each compressor of each outdoor unit are determined.Through the comparative analysis of experimental test data,the whole system can achieve 15%energy-saving operation when it is in the best energy efficiency state.
