摘　　要：本文探讨了中央空调系统冷水机组的功耗通用数学模型及其推导过程,该模型为半经验模型。通过冷却水变流量运行条件下的实验数据验证了该模型的与准确性,并在此基础上用另两种方法进行简单的修正,通过对比三种方法的功耗计算结果,发现修正后的模型具有更高的通用性。A general energy consumption mathematical model, which is a semi-empirical model, with the derivation of a water cooled chiller in central air-conditioning system was discussed. The model was demonstrated correct and accurate by the experimental data of the cooling water under the condition of variable flow operation. On the basis of the original model, two methods of correction were proposed. The results show that the revised model had higher versatility by comparing three methods of energy consumption calculation results.
