In the article discusses the features of work air handling unit (AHU) based on spray chamber (SC), developed the design of the test bench and presents the results of the tests SC, identify ways to improve them, particularly in the lower part of the workspace was placed plane-parallel packing. It was established experimentally that the efficiency of processes of heat and moisture transfer increased by an average of 6 - 10%.
