The goal of the Spatial Environmental Control Unit as a continuation based on the Multifunctional Environmental Control Unit is to create a user friendly accurate analysis and control of heat transfer dynamics in a spatial area that is responsive to the thermal dynamics of the area of interest and accurate to maintain an acceptable level of thermal control as environmental and human biological conditions change without requiring excessive interruptions to the user for manual adjustment. The Spatial Environmental Control Unit (SECU) makes the current norm of an absolute temperature control approach for thermal control and human comfort obsolete. A COMFORT theory of relativity will now be the new norm. The proposed dynamic process of mapping and analyzing the thermal changes rapidly within the area of interest responds to the unpredictable thermal changes in environment better than the best static or learning process currently available. Even though the current learning process for thermal control makes periodic changes based on logged user preferences as a function of time, it still controls for extended time, periods with a single static temperature set point. Basically, a series of a series of static control sequences as a function of time. The proposed Spatial Environmental Control Unit incorporates the dynamics of analyzing real time thermal changes with timely feedback from the user.
