空调大温差研究(1):经济分析方法

Research of large temperature difference in air conditioning(1): Economic analysis methods

阐述了空调大温差送风技术的概念 ,以风机和水泵的能耗计算为例 ,分析了目前在评价空调大温差系统经济性时所采用的计算方法 ,认为这些计算结果导致对经济效益评价过高。

Defines the large temperature difference technique, analyses the calculating methods presently used abroad in evaluating the economic efficiency of air conditioning design with a large temperature difference. Considers that the calculating results by these methods lead overestimation of the system economy, particularly in evaluating the energy consumption of fans and water pumps. Recommends an improved method of economic analysis for the air conditioning design with a large temperature difference.
