Design a feedback control system of an air conditioning system to achieve the desired room temperature level by setting the value using an input device. The design must be presented using a block diagram that indicates all 1) required control elements, 2) direction of signals flow, 3) input and output of the required elements, and 4) the transfer function of the elements. Using the block diagram, explain operation of the system using the transfer function and the flow of the signal.
