Problems solved by technology

However, the bypass channels disclosed in the prior art have the disadvantage here that the gas flow leaving the evaporator and the bypass channel do not mix well with each other, which can not only lead to undesired temperature strands and thus damage Impairment of comfort, at worst, stratified airflow and steaming of the windshield, which can also impair driving safety
Furthermore, the detrimental and in particular non-regenerative mixing of the air flow from the evaporator with the bypass channel prevents the adjustment of the air conditioning unit to achieve a regenerative continuous regulation curve

Embodiment Construction

[0030] corresponds to figure 1 and figure 2 , the inventive air conditioning unit 1 of a car 2 (or not shown) has a fan 3 and a casing 4, wherein both the evaporator 5 and the heat exchanger 6 downstream thereof are arranged in the casing 4. The heat exchanger 6 is preferably used here exclusively as a heating device for heating the gas flow 9a flowing through it. According to the invention, there is now provided a first bypass channel 7 bypassing the evaporator 5 , which is centrally arranged on one side of the evaporator 5 and whose width b is smaller than the width B of the side of the evaporator 5 on which it is arranged. according to figure 1 and figure 2 , the width b, B here extends perpendicularly to the screen and can therefore only be in Figure 3 to Figure 5a , 5b are seen. In this arrangement, the width b of the first bypass channel 7, like the width B of the evaporator 5, is applied independently of the spatial orientation, so that the first bypass channel...

Abstract

The invention relates to an air conditioning unit (1) of a motor vehicle (2) having a fan (3), an evaporator (5) and a heat exchanger (6) arranged downstream thereof, both arranged in a casing (4), The first bypass channel (7) bypasses the evaporator (5). It is essential for the invention that the first bypass channel (7) is arranged centrally on one side of the evaporator (5) and that its width (b) is smaller than the width (B) of the side of the evaporator (5) on which it is arranged . This enables a particularly uniform air flow.

Description

technical field [0001] The invention relates to an air conditioning unit of a motor vehicle with a fan. The invention also relates to a motor vehicle equipped with such an air conditioning unit. Background technique [0002] DE19731369C1 discloses a common air-conditioning unit for motor vehicles with a fan and an evaporator, wherein a bypass channel bypassing the evaporator is provided. [0003] Another common air conditioning unit is known from DE 2010029495 A1. [0004] CN201205858Y and JP2006027377A disclose air conditioning units. [0005] In order to maximize the efficiency of current air conditioning units, the goal is to use only as much cooling or heating energy in the air conditioning units as is actually required to achieve or maintain climate comfort in the passenger compartment. Avoiding unnecessary cooling and heating energy has a negative impact on operating range, especially in electric vehicles. [0006] Current air conditioning units with regulated, ext...
