Abstract
Description
Die vorliegende Erfindung betrifft ein Klimagerät gemäß dem Oberbegriff des Patentanspruches 1.The The present invention relates to an air conditioner according to the preamble of claim 1.
In manchen Fahrsituationen ist es wünschenswert, den Fahrgastraum eines Fahrzeugs über die in der Instrumententafel vorgesehenen Oberkörperluftauslässe zu kühlen und gleichzeitig warme Luft über die Defroster- bzw. Frontscheibenluftauslässe auszublasen, um ein Beschlagen der Frontscheibe zu vermeiden. Bei herkömmlichen Klimageräten besteht in derartigen Situationen üblicherweise das Problem, dass kühle Luft, die eigentlich über die Oberkörperluftauslässe in den Fahrgastraum strömen soll, zu den Defroster- bzw. Frontscheibenluftauslässen gelangt, was ein Beschlagen der Frontscheibe zur Folge haben kann.In some driving situations it is desirable the passenger compartment of a vehicle over the in the instrument panel provided upper body air outlets to cool and at the same time warm air over blow out the defroster or windscreen air outlets to fog up to avoid the windscreen. In conventional air conditioners exists in such situations usually the problem that cool Air, actually over the upper body air outlets in the Passenger room stream should, to the Defroster- or Frontscheibenluftauslässen what may cause fogging of the windscreen.
Aufgabe der Erfindung ist es, ein Klimagerät zu schaffen, das es ermöglicht, vom Verdampfer gelieferte Kaltluft direkt zu Oberkörperluftauslässen zu leiten und gleichzeitig warme Luft, deren Temperatur über der der über die Oberkörperluftauslässe ausströmenden Luft liegt, zu den Defroster- bzw. Frontscheibenluftauslässen zu leiten.task the invention is to provide an air conditioner that makes it possible direct cold air supplied by the evaporator to upper body air outlets and at the same time warm air whose temperature is above that of the Upper body air outlets discharging air is to the defroster or Windlassluftauslässen too conduct.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Ausgangspunkt der Erfindung ist ein Klimagerät zur Klimatisierung eines Fahrgastraums eines Fahrzeugs, das die üblichen Komponenten aufweist, nämlich ein Gehäuse mit mindestens einem Oberkörperluftauslass und mindestens einem Frontscheibenluftauslass, einen zum Kühlen von Luft vorgesehenen Verdampfer, einen zum Erwärmen von Luft vorgesehenen Heizwärmetauscher und einen in dem Gehäuse befindlichen Mischraum zum Mischen von vom Verdampfer kommender Kaltluft mit vom Heizwärmetauscher kommender Warmluft.starting point The invention is an air conditioner for the air conditioning of a passenger compartment of a vehicle, which is the usual Has components, namely a housing with at least one upper body air outlet and at least one windscreen air outlet, one for cooling Air provided evaporator, one intended for heating air heating heat exchanger and one in the housing mixing space for mixing coming from the evaporator Cold air from the heating heat exchanger coming warm air.
Der Kern der Erfindung besteht darin, dass in dem Gehäuse mindestens ein Kaltkluftkanal angeordnet ist, der dazu vorgesehen ist, vom Verdampfer kommende Kaltluft separiert von der im Mischraum befindlichen Luft direkt in Richtung zu dem mindestens einen Oberluftauslass zu leiten. Im Unterschied zu herkömmlichen Klimageräten besteht also die Möglichkeit, Kaltluft direkt vom Verdampfer zu dem mindestens einen Oberkörperluftauslass zu leiten, d. h. ohne dass die über den mindestens einen Oberkörperluftauslass in den Fahrgastraum ausströmende Luft ganz oder zu einem Teil zuvor den Mischraum durchströmt hat.Of the Essence of the invention is that in the housing at least a Kaltkluftkanal is arranged, which is intended to be from Evaporator coming cold air separated from that located in the mixing chamber Air directly towards the at least one upper air outlet to lead. In contrast to conventional air conditioners exists So the possibility Cold air directly from the evaporator to the at least one upper body air outlet to lead, d. H. without that over the at least one upper body air outlet emanating into the passenger compartment Air has flowed through all or part of the mixing chamber before.
Dadurch wird der bei vielen herkömmlichen Klimageräten anzutreffende unerwünschte Effekt vermieden, dass bei einer Belüftung des Fahrgastraums mit kühler Luft über die Oberkörperluftauslässe die Temperatur der über die Defroster- bzw. Frontscheibenluftauslässe ausströmenden Luft unter den Taupunkt absinkt und sich Feuchtigkeit an der Frontscheibe niederschlägt. Gemäß der Erfindung ist also mindestens ein „Kaltluftbypasskanal" vorgesehen, welcher „die Strömungsverbindung" zwischen dem Mischraum des Kli mageräts und dem mindestens einen Defroster- bzw. Frontscheibenluftauslass „kreuzt".Thereby will be found in many conventional air conditioners undesirable Effect avoided that with aeration of the passenger compartment with cooler Air over the upper body air outlets the Temperature of over the defrost or windscreen air outlets discharge air below the dew point drops and moisture is reflected on the windscreen. According to the invention So at least one "cold air bypass channel" is provided, which "the flow connection" between the mixing chamber of the Kli mageräts and "crossing" at least one defroster or windscreen air outlet.
Nach einer Weiterbildung der Erfindung sind mehrere solche „Kaltluftbypasskanäle", die im folgenden auch kurz als „Kaltluftkanäle" bezeichnet werden, vorgesehen. Vorzugsweise sind die Kaltluftkanäle im wesentlichen quer zur Strömungsrichtung der aus dem Mischraum zu dem mindestens einem Frontscheibenluftauslass ausströmenden Luft angeordnet. Ähnlich wie bei einem Kreuzstromwärmetauscher kreuzen sich also zwei Luftströme, nämlich ein über die Kaltluftkanäle zu den Oberkörperluftauslässen geleiteter Kaltluftstrom und ein im wesentlichen quer dazu vom Mischraum zu den Defroster-Luftauslässen strömender wärmerer Luftstrom, der ein Beschlagen der Frontscheibe verhindern soll.To In a further development of the invention, several such "cold air bypass ducts" are described below also referred to as "cold air channels" for short, intended. Preferably, the cold air ducts are substantially transverse to flow direction from the mixing chamber to the at least one windscreen air outlet outflowing Air arranged. Similar as in a cross-flow heat exchanger so two streams of air intersect, namely one over the cold air channels directed to the upper body air outlets Cold air flow and a substantially transverse to the mixing chamber to the warmer airflow flowing to the defroster air outlets, which is intended to prevent fogging of the windscreen.
Die Kaltluftkanäle sind vorzugsweise beabstandet nebeneinander angeordnet. Sämtliche Kaltluftkanäle können parallel zueinander angeordnet sein.The Cold air ducts are preferably spaced next to each other. All Cold air ducts can be arranged parallel to each other.
Ähnlich wie bei herkömmlichen Klimageräten kann der Mischraum einen „Zugang" für vom Heizwärmetauscher kommender Warmluft und einen Zugang für vom Verdampfer kommender Kaltluft aufweisen, so dass die beiden Luftströme vereinigt und auf eine gemeinsame Mischtemperatur gebracht werden können. Um sicherzustellen, dass bei gleichzeitigem Einleiten von Warmluft und Kaltluft in den Mischraum hinreichend viel Warmluft zu den Defrosterauslässen gelangen kann, sind gemäß der Erfindung im Bereich des „Mischraumeinlasses", über den vom Verdampfer kommende Kaltluft in den Mischraum gelangt, mehrere Luftleitelemente beabstandet nebeneinander angeordnet, die in Bezug auf die in den Mischraum einströmende Kaltluft eine Art „Blende" mit mehreren durch die voneinander beabstandeten Luftleitelemente gebildeten Lufteinlassschlitzen bilden. Im „Windschatten der Luftleitelemente" kann dann vom Heizwärmetauscher kommende Warmluft zu den Defrosterluftauslässen strömen und zwar auch dann, wenn über die durch die Luftleitelemente gebildeten Schlitze quer zu der Warmluftströmung vom Verdampfer kommende Kaltluft in den Mischraum eingeleitet wird.Similar to at conventional Air conditioners can the mixing room an "access" for from the heating heat exchanger coming warm air and access for coming from the evaporator Have cold air, so that the two air streams combined and on a common Mixing temperature can be brought. To ensure, that with simultaneous introduction of hot air and cold air into the mixing chamber Sufficient hot air can reach the Defrosterauslässen are according to the invention in the area of the "mixing room inlet", above the Evaporator incoming cold air passes into the mixing chamber, several air guide elements spaced side by side, with respect to the in the Mixing room inflowing Cold air a kind of "aperture" with several through form the air inlet slots formed spaced apart air guide elements. In the "slipstream the spoiler elements "can then from the heating heat exchanger incoming hot air to the defroster air outlets flow and even if over the through the air guide elements formed slots across the hot air flow from Evaporator coming cold air is introduced into the mixing chamber.
Vorzugsweise ist eine Vielzahl solcher Luftleitelemente parallel nebeneinander angeordnet.Preferably is a plurality of such air guide parallel to each other arranged.
