AI Technical Summary

Technical Problem

It is difficult for existing HVAC modules to provide air adapted to temperature, humidity and air volume to different areas inside a motor vehicle at the same time, resulting in limited passenger comfort.

Method used

By dividing the air path into the main path and the side path in the HVAC module, and using the first and second valve flaps to control the air flow cross-section, the air supply of different areas can be independently adjusted for air volume, temperature and humidity.

Benefits of technology

It realizes personalized ventilation condition adjustment in different areas inside the motor vehicle, improves passenger comfort, and reduces the energy consumption of the HVAC module by optimizing valve flap adjustment.

Abstract

The invention relates to an HVAC module (1), in particular for a motor vehicle, having an air path (2) for the passage of air. An evaporator (8) and a heating device (9) are arranged in the air path,the evaporator and the heating device dividing the air path into a main path (3) passing through the evaporator and the heating device, and a side path (4) extending fluidly parallel to the main pathand bypassing the evaporator and the heating device. The side path branches off from the main path upstream of the evaporator and flows back into the main path downstream of the heating device and isfluidly connected to the main path between the evaporator and the heating device. The side path includes a first side path portion (5a) bypassing the evaporator and a second side path portion (5b) bypassing the heater. The HVAC module further comprises a first flap (10a) located in the air path and adjustable between a closed position and an open position. The HVAC module further comprises a second flap (10b) arranged in the air path and adjustable between first, second and third positions.
