As the era of fully autonomous driving approaches, the purpose of the vehicle will change from a vehicle to a living space like a home. For this, it is necessary to change the space in which the passengers stay. For this change, the indoor space is secured larger than before. To do this, the reduction of existing indoor parts is essential. It is thought that the change of the cockpit located in front of the current vehicle will be most prominent. For the change ofcockpit, the representative part that occupies the largest volume among the parts located inside It is a hvac system for indoor cooling/heating. This cooling/heating system has a direct effect on mileage It must be a system capable of responding to heat pump systems, and the interior volume must be reduced to respond to changes. For this, the temperature control door inside the hvac is removed, and the hvac system capable of constructing a heat pump system Development review.

As we develop a platform for electric vehicles, slim cockpits, swivel seats, and flat floors are required to expand indoor space. In order to cope with this, a new type of HVAC concept needs to be reviewed. In this paper, the HVAC mounting location and structure were optimized for cockpit slimming. In order to secure an indoor space, the concept of moving the blower unit and the heater & evap unit of HVAC mounted indoors to the PE room has been implemented. The HVAC in the PE room was optimized considering the layout with the surrounding parts, and the performance was verified through the HVAC internal flow analysis and system bench experiment. Based on the results, the PE room HVAC concept can be applied to electric vehicle platforms in the future to commonize platforms and secure indoor space.
