The room air conditioning strategy should be used as a target for design and construction of the room air conditioning system. Often it would be desirable to apply several strategies during different operating conditions (e. g., sum­mer-winter). The selection of the system and the set of methods (room air dis­tribution, exhaust, heating, cooling) should be made in such a way that the different strategies can be applied most efficiently.

The clarification of the room air conditioning strategies and their separa­tion from the practical methods at present creates space for creativity and new innovations and their evaluation.

Naming a practical room air distribution method according to a certain strategy may lead to misunderstanding of its performance in varying operating conditions. Though naming probably can’t be avoided in business, an under­standing of the basic strategies helps customers evaluate offered practical air distribution methods and system solutions.
