Development of Heat Transfer Relationship for Modeling Energy Use in a Room

Abstract

In a room, the use of minimal energy and the provision of necessary comfort are the most desired results. To achieve this result, optimum control must be achieved in the heaters and coolers that consume the most energy.  In this study, a heat transfer model was developed to be used in optimal control methods in order to provide energy saving in a an anvironmental room by keeping comfort conditions. This model has been examined on the basis of a simulation. A test chamber established for this was taken as basis and the behavior of the heat transfer relation based on the energy balance was determined according to the time.  The dynamics of thermal effects are described by the variables and model parameters described herein. The results show that the heat transfer model established for a selected room is stable.  When the natural response of the system is taken into consideration, it is seen that it is stable without growing and not oscillating.    The heat transfer model presented herein may at least be used in achieving a satisfactory control task. Simulation studies demonstrate that this model can be applied in environmental spaces and show that the results are promising.
