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.

Recently Car-maker has improved efficiency of engine because customers prefer car with increased fuel efficiency For this reason, PTC heater has been applied with diesel engine since past 10 year for heating performance. Furthermore heat source continually reduced in Gasoline engine because of improvement of gasoline engine efficiency. So PTC heater is also applied to Gasoline engine. Recently trend is to increase using of PTC heater. Like this PTC heater of auxiliary heater has been transformed into the main heater. But PTC heater has increasing HVAC package. Also, PTC heater has increasing temperature distribution and decreasing heating performance because cold air is bypassed. This paper is about studying hybrid PTC heater that is improved about disadvantages of PTC heater. Hybrid PTC heater is composed of an efficiently combination of thin PTC heater with coolant heater core. This paper presents experimental results of heating performance test at vehicle level. As a result, Hybrid PTC heater could improve interior temperature of vehicle about 0.9℃~3℃

In relation to the vehicle air conditioning system, the recent trend is a trend that a growing number of complaints and requirements of the customers for rear seat. As you can see in the IQS and the Internet Community and Overseas Magazine assessment, complaint and requirements for comfort of rear seat it is not limited to large cars. The 4-Zone and 3-Zone system that can control rear seat independently application is required in order to meet these consumer desires. However, the system has high cost and difficult to apply for under midrange car. Therefore, it is necessary functionality is implemented, but the price is inexpensive entry-level systems development. So I started to research this theme, ‘A development of the entry-level console ventilation structure of floor mode’. It wants to improve through this study as follows. First, Heating Performance Improvement (IQS and VDS improvement), second, the number of parts and size reduction compared to existing structures(Cost and weight saving), Third, entry-level concept development(Extended to midrange cars)
