AI Technical Summary

Technical Problem

Existing heating, ventilation, and air conditioning (HVAC) units in motor vehicles face challenges with liquid accumulation due to rain or condensation, leading to stagnation and potential microbial contamination, and current drainage solutions increase unit size and cost due to complex internal partition configurations.

Method used

A HVAC unit design featuring external, flexible tubes connecting liquid collectors to a drainage passage, eliminating the need for complex internal conduits, with the drainage passage located at the lower part of the unit and external tubes guiding liquid flow to the evacuation point.

Benefits of technology

Simplifies the drainage process, reducing unit size and cost while preventing liquid stagnation and microbial growth, ensuring efficient liquid removal without obstructing airflow.

Abstract

A heating, ventilation, and / or air conditioning unit, particularly for motor vehicles, said unit comprising a body (2) defining an air inlet channel (4) and a first housing (6) for one or more heat exchangers intended to cool and / or heat said air inlet, said unit comprising a liquid drain passage (8) located at a distance from said inlet channel (4) and / or said first housing (6), said body (2) further comprising at least one liquid collector (10, 12) at the level of said inlet channel (4) and / or said first housing (6), said unit comprising at least one pipe (14, 16) attached to said body (2) to allow the liquid to flow from said collector(s) (10, 12) to said drain passage (8).
