Analyzing Alternatives in the Scope of Product Design and Development for Effective Control towards Defogging in an Automotive Cabin

Passenger safety is considered as the central issue in vehicle design since many years. One of the important factors that strongly affect driving safety is visibility through the windshield. Tools available for this purpose are sensor based and may lead to misfiring. Mathematical models available largely do not account the effects of latent heat and humidity. The performance of the A/c in the light of `Defogging' involves thermal parameters to be controlled while the Product Design and Development of the same involves tools to be deployed in realizing a commercial product. Both the aspects shall be evaluated with emphasis on the `Product Development' of the solution. The model shall help in predicting fogging and understanding the actual thermal parameters leading to it and hence can be useful in optimizing these parameters so as to reduce fogging. It should serve as a useful tool in optimizing the performance of an air conditioner while making the product viable for development and manufacturing further.
