Abstract: Aspects of embodiments relate to an air conditioning system for generating a controlled environment in a room, the AC system comprising one or more processors and one or more memories to cause the system to perform the following: sensing one or more characteristics of a condition of a room; providing a sensor output which is descriptive of the one or more sensed characteristics of the room; analyzing the sensor output to yield an analysis result; and selectively controlling by a controller, based on the analysis result, for example, an output airstream velocity of the plurality of room blowers of the AC system which are arranged such that a lower plenum of the room is in parallel downstream fluid communication relative to the plurality of room blowers.
