Abstract
Description
Die Erfindung betrifft eine Kraftfahrzeug-Klimaanlage mit einem Kältemittelkreislauf und mit mindestens einem Kompressor, einem Expansionsorgan und einem Verdampfer, wobei der Verdampfer einen Kältespeicher umfasst.The invention relates to a motor vehicle air conditioning system with a refrigerant circuit and with at least one compressor, an expansion element and an evaporator, wherein the evaporator comprises a cold storage.
Manche Fahrzeuge sind mit einer sog. Start-/Stoppautomatik ausgestattet, welche den Verbrennungsmotor aus Effizienzgründen während Stauphasen bzw. wenn das Fahrzeug an einer Ampel steht, vorübergehend abschaltet und beim erneuten Anfahren automatisch wieder startet. Auch bei Hybridfahrzeugen, d. h. Fahrzeugen, die mit einem Verbrennungsmotor und zusätzlich mindestens einem Elektromotor, der ein elektrisches Fahren ermöglicht, ausgestattet sind, gibt es Betriebsphasen, in denen der Verbrennungsmotor ausgeschaltet ist und das Fahrzeug ausschließlich elektromotorisch betrieben wird. Um in Phasen, in denen der Verbrennungsmotor abgestellt ist, die Klimatisierung des Fahrgastraums aufrecht zu erhalten, ist es bekannt, den Verdampfer des Kältemittelkreislaufs der Klimaanlage so zu konzipieren, dass er für eine begrenzte Zeit Kälteleistung zur Verfügung stellen kann, auch wenn die Klimaanlage nicht vom Verbrennungsmotor angetrieben wird. Derartige Verdampfer weisen integrierte Kühlmedien zur Kältespeicherung auf, um bei abgeschaltetem Verbrennungsmotor, wenn der Verdichter der Klimaanlage nicht angetrieben wird, für einen begrenzten Zeitraum Kälteleistung zur Verfügung stellt. Some vehicles are equipped with a so-called. Automatic start / stop, which temporarily shuts off the engine for stoppage phases or when the vehicle is at a traffic light for efficiency reasons and automatically restarts when re-starting. Also in hybrid vehicles, d. H. Vehicles equipped with an internal combustion engine and in addition at least one electric motor enabling electric driving, there are operating phases in which the internal combustion engine is switched off and the vehicle is operated exclusively by an electric motor. In order to maintain the air conditioning of the passenger compartment in phases in which the internal combustion engine is switched off, it is known to design the evaporator of the refrigerant circuit of the air conditioning system so that it can provide cooling capacity for a limited time, even if the air conditioning system is not is driven by the internal combustion engine. Such evaporators have integrated coolants for cold storage to provide refrigeration capacity for a limited period of time when the internal combustion engine is off when the compressor of the air conditioner is not driven.

Demgegenüber besteht die Aufgabe der vorliegenden Erfindung eine Kraftfahrzeug-Klimaanlage mit einem Verdampfer bereitzustellen, der konstruktiv vereinfacht aufgebaut ist und trotzdem in Stoppphasen eines Kraftfahrzeugs mit Start-/Stoppautomatik Kälte bereitstellt.In contrast, the object of the present invention to provide a motor vehicle air conditioning system with an evaporator, which is constructed in a simplified design and still provides cold in stop phases of a motor vehicle with start / stop automatic.
Diese Aufgabe wird durch die in Anspruch 1 wiedergegebene Kraftfahrzeug-Klimaanlage gelöst.This object is achieved by the recited in claim 1 automotive air conditioning.
Dadurch, dass der Kältespeicher als eine an dem Verdampfer angeordnete thermische Masse ausgebildet ist, ist es möglich, ähnlich einem Speicherverdampfer, während der Fahrt des Kraftfahrzeugs Kälte zu speichern, die im Stillstand (Stopp-Phase) genutzt bzw. abgegeben werden kann. Diese Bauweise bringt eine erhebliche Vereinfachung mit sich, da keine doppelwandigen Rohre, gesonderte Kreisläufe etc. benötigt werden. Somit kann der Verdampfer ohne größeren technischen Aufwand länger kalt gehalten werden.Characterized in that the cold storage is designed as a arranged on the evaporator thermal mass, it is possible, similar to a storage evaporator, while driving the motor vehicle to store cold, which can be used or delivered at a standstill (stop phase). This design brings a considerable simplification, since no double-walled pipes, separate circuits, etc. are needed. Thus, the evaporator can be kept cold longer without major technical effort.
Die thermische Masse kann einerseits eine luftdurchlässige Rippenstruktur aufweisen. Dann ist Ihre Anbringung vor und/oder hinter der Luftauslassseite bzw. Lufteinlassseite des Verdampfers möglich, da die Luft weiterhin ungehindert durch den Verdampfer strömen kann. Diese Bauweise hat den Vorteil, dass die thermische Masse schnell Kälte aufnehmen bzw. an die Kühlluft abgeben kann.The thermal mass may on the one hand have an air-permeable rib structure. Then your attachment before and / or behind the air outlet side or air inlet side of the evaporator is possible because the air can continue to flow unhindered through the evaporator. This design has the advantage that the thermal mass quickly absorb cold or can deliver to the cooling air.
Dazu kann die thermische Masse flächig an der Luftauslassseite bzw. Lufteinlassseite des Verdampfers angeordnet werden. Alternative kann die thermische Masse in einen entsprechenden Luftfilter am Verdampfer integriert werden.For this purpose, the thermal mass can be arranged flat on the air outlet side or air inlet side of the evaporator. Alternatively, the thermal mass can be integrated into a corresponding air filter on the evaporator.
Andererseits kann die thermische Masse blockartig ausgebildet sein. Dann bietet sich eine Anbringungsstelle am Verdampfer an, wo die Luftströmung nicht behindert wird, aber trotzdem ein guter Kontakt mit den Kühlelementen (z.B. Rippen) des Verdampfers möglich ist. So kann die thermische Masse am oberen und/oder unteren Rand an der Luftauslassseite und/oder Lufteinlassseite des Verdampfers angeordnet sein. Alternativ oder zusätzlich kann die thermische Masse oberhalb und/oder unterhalb des Verdampferkerns angeordnet werden oder an die seitlichen Endtanks befestigt sein.On the other hand, the thermal mass may be block-shaped. Then an attachment point to the evaporator is provided where the air flow is not obstructed, but nevertheless good contact with the cooling elements (e.g., fins) of the evaporator is possible. Thus, the thermal mass can be arranged at the upper and / or lower edge on the air outlet side and / or air inlet side of the evaporator. Alternatively or additionally, the thermal mass above and / or below the evaporator core may be arranged or attached to the side end tanks.
Es versteht sich, dass es auch im Rahmen der Erfindung möglich ist, die unterschiedlichen Anbringungsstellen und Bauweise beliebig zu kombinieren, wenn dies der zur Verfügung stehende Raum im Fahrzeug zulässt.It is understood that it is also possible within the scope of the invention to combine the different attachment points and design as desired, if this allows the space available in the vehicle.
