某卷烟厂冷水机组运行的性能研究

Performance of Chiller in a Tobacco Factory

对某卷烟厂冷水机组运行时进行实验研究,结果表明分别在60%、90%负荷运行时,实际COP值为3.83、4.60,小于该机组的名义工况下5.53的COP值。建议在原空调系统上增加温差控制器和变频器,以控制冷却水泵和冷冻水泵的工作状态,保证该冷水机组的COP在最优化的节能运行状态,从而降低系统的能耗。

The chiller generator operation of a tobacco factory is researched experimentally. Resultsshow that the actual COP is 3.84 or 4.60 in 60%or 90%load operation respectively, that is less than theCOP value of 5. 53 under the the normal working condition of the unit. In order to optimize the COP of thechiller under energy - saving running state to reduce the energy consumption of the system, the papersuggests adding temperature controller and frequency converter in the original air conditioning system tocontrol the working status of the cooling water pump and chilled water pump.
