Description

Integrated Door Air Conditioning System for Vehicles The present invention relates to an air conditioning system for a vehicle, and more specifically, to an integrated door air conditioning system for a vehicle comprising a foot door unit that performs the function of opening and closing a foot vent and a separation door unit that separates the flow path at the rear end of a heat exchanger vertically. Recently, more efficient and space-saving technological developments are underway in the design of vehicle heating, ventilation, and air conditioning (HVAC) systems. In particular, with the application of HVAC systems, including slim ducts, to vehicles, methods to effectively open and close foot vents and separate upper and lower airflow paths while simultaneously increasing the efficiency of interior space have emerged as important technical challenges. Foot vents are a critical component for regulating airflow within a vehicle, and continuous improvements are being made to maximize driver comfort and air circulation efficiency. Conventionally, butterfly-type foot doors were widely used to separate the upper and lower airflow paths. In this structure, when the foot door opened, air from the bottom was discharged upward, and when the foot door closed, the upper and lower airflow paths were separated. While this system had the advantage of effectively controlling the upper and lower airflow paths, the HVAC package had to be extended forward to secure the opening range and airflow path of the foot door. These structural constraints were disadvantageous for securing living space inside the vehicle, becoming a limitation in the interior design of modern vehicles, which require a slim design. To solve the problems of the conventional technology, research was needed on a new design method that can minimize the space of the air conditioning package while more efficiently performing the functions of opening and closing the foot vent and separating the upper and lower airflow. In response to this need, the present invention aims to provide a technical solution that improves the performance of the air conditioning system in a vehicle and maximizes interior space utilization by presenting a new foot door unit that integrates a foot door and a separation door unit.
