Classification for the room air conditioning strategies

This paper introduces a new strategy approach for the room air conditioning including classification and terminology. The aim of the classification is not to value one strategy over another (piston, stratification, zoning and mixing strategies are presented with their advantages and drawbacks, design criteria and applications) , it is up to the designer to select the most desirable strategy for each case. A clear classification of the ideal strategies will help the evaluation of the present room air distribution methods in different operating conditions. The strategy can be changed by using combinations of available methods.It is important to separate the ideal strategies from the practical room air conditioning solutions.
