Analysis of influence of IEC heat exchanger based on CFD method

Abstract In order to reduce energy consumption and make full use of indoor air exhaust, we studied the heat exchanger in the indirect evaporative cooling (IEC) energy recovery system. The influence of inlet air temperature, relative humidity, mass flow rate and channel height on the heat exchange capacity of heat exchangers under conditions including high temperature and high humidity was studied. The results show that higher inlet temperature and relative humidity will lead to lower outlet temperature. moisture content and more condensation quantity. Smaller channel height facilitates heat transfer.
