Heating ventilating and air conditioning device for a vehicle

摘要

The invention relates to an HVAC device for a vehicle including an inlet casing, an air distribution casing, and a blower located in a blower casing for drawing air through the inlet casing and delivering the air into the air distribution casing. The device further includes an evaporator in the air distribution casing and a drainage system below the evaporator for draining off liquid condensed out of the air at the surface of the evaporator into the environment of the HVAC device. The inlet casing is positioned such that liquid penetrating the inlet casing accumulates in a lower area of the inlet casing. Between the lower area of the inlet casing and the drainage system of the liquid condensed out at the evaporator, a hydraulic connection is configured such that the liquid is drainable from the inlet easing past the blower casing and evaporator into the drainage system.

主权项

1. A heating ventilating and air conditioning device for a vehicle comprising:
an inlet casing; an air distribution casing in fluid communication with the inlet casing; a blower disposed in a blower casing and in fluid communication with the air distribution casing, the blower drawing air through the inlet casing and into the air distribution casing; an evaporator disposed within the air distribution casing beneath the blower; and a drainage system disposed below the evaporator for draining a liquid condensed from air at a surface of the evaporator, wherein the liquid in the air flowing through the inlet casing accumulates in a lower portion of the inlet casing, and wherein the liquid condensed from the air at the surface of the evaporator drains from the inlet casing, through a hydraulic connection disposed between the lower portion of the inlet casing and the drainage system, past the blower casing and evaporator, and into the drainage system, so the liquid in the air flowing through the inlet casing and the liquid condensed from the air at the surface of the evaporator join and flow through the hydraulic connection.
