Virtual Design of HVAC Systems with Simulation under Competing HVAC Noise and Defrost Performance Requirements
It is particularly easy to get tunnel vision as a domain expert, and focus only on the improvement one could provide in their area of expertise. To make matters worse, many organizations at OEMs are silo-ed by domain of expertise, unconsciously promoting this single mindedness in design. Unfortunately, the successful and profitable development of a vehicle is dependent on the delicate balance of many domains, involving multiple physics and departments. Taking for instance the design of an HVAC system, the device’s primary function is to control the climate system in vehicle cabins, and more importantly to make sure that critical areas on the windshield can be defrosted in cold weather conditions within regulation time. With the advent of electric and autonomous vehicles, further importance is now also placed on the energy efficiency of the HVAC, and its noise.
