基于能耗考虑的交叉流显热换热器性能评价方法
Performance evaluation for cross-flow plate sensible heat exchangers based on energy consumption
摘要：
提出了根据实验数据和ε-NTU关系式求解交叉流板式显热换热器各种通道形式对流传热关联式的方法。考虑到换热器会给空调系统带来阻力损失，建议用回收热量与风机有效功率的比值来评价换热器的节能性能，并对两种通道形式的交叉流板式显热换热器进行了性能比较。

Abstract：
Puts forward the method of solving the convectional heat transfer relation of different channel forms of cross-flow plate sensible heat exchangers(CPSHE) based on the experimental data and ε-NTU relation. Considering that the heat recovery device causes pressure loss for CPSHE used in air conditioning systems, proposes evaluating the energy saving performance of CPSHE by the ratio of heat recovery quantity to the effective power of fans and compares the performance of two channel forms of CPSHE.
