Abstract
Description
Die Erfindung betrifft eine Klimaanlage für Fahrzeuge nach den Merkmalen des Oberbegriffes des Anspruch 1.The invention relates to an air conditioner for vehicles according to the features of the preamble of claim 1.
Bei Klimaanlagen in Fahrzeugen stellt
sich in der Praxis oftmals das Problem der Verkeimung und daraus
resultierend eine Geruchsbelästigung
bis hin zu einer Gesundheitsgefährdung.
Um dem vorzubeugen ist es z. B. aus der
Aus der
Die
Ein im Hinblick auf Verkeimung kritisches Bauteil der Klimaanlage ist der Verdampfer. Beim Betrieb der Klimaanlage wird dieser infolge sich abscheidender Luftfeuchtigkeit nass und weist gute Entwicklungsbedingungen für mikrobielle Belastungen, wie z. B. Keime oder Sporen auf.A critical component in terms of microbial contamination the air conditioner is the evaporator. When operating the air conditioning This gets wet as a result of precipitating humidity and points good development conditions for microbial loads, such. B. germs or spores.
Der Erfindung liegt die Aufgabe zugrunde, eine Klimaanlage zu schaffen, die konstruktiv einfach aufgebaut ist und eine geringe mikrobielle Belastung für die zu klimatisierenden Räume aufweist.The invention is based on the object To create air conditioning, which is structurally simple and has a low microbial load on the rooms to be air conditioned.
Diese Aufgabe wird erfindungsgemäß durch eine Klimaanlage nach den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a Air conditioning solved according to the features of claim 1.
Die Klimaanlage weist eine Steuervorrichtung auf, die den Kältemittelkreislauf umschaltet. So wird der Verdampfer in einem ersten Schaltzustand gekühlt um wie bei einer herkömmlichen Klimaanlage die durch den Verdampfer strömende Luft zu kühlen. In einem zweiten Schaltzustand wird der Verdampfer geheizt, so dass Mikroben und/oder Sporen und/oder Keime durch erhitzen abgetötet werden. Durch Wahl eines entsprechenden Kältemittels, wie z. B. CO2 oder R134 kann der Kältemittelkreislauf durch umdrehen der Förderrichtung des Kältemittels umgeschaltet werden, so dass die Klimaanlage im ersten Schaltzustand als Kälteanlage und im zweiten Schaltzustand als Wärmepumpe arbeitet, wobei der Verdampfer erhitzt wird.The air conditioner has a control device on that the refrigerant circuit switches. Thus, the evaporator is cooled in a first switching state as in a conventional Air conditioning to cool the air flowing through the evaporator air. In a second switching state, the evaporator is heated, so that Microbes and / or spores and / or germs are killed by heating. By choosing a suitable refrigerant such. B. CO2 or R134 can be the refrigerant circuit by turning the conveying direction of the refrigerant be switched so that the air conditioner in the first switching state as a refrigeration system and in the second switching state operates as a heat pump, wherein the evaporator is heated.
In einer Ausführung kann vorgesehen sein, dass die Förderrichtung des Kompressors umschaltbar ist, so dass durch ansteuern des Kompressors der Kältemittelkreislauf umgeschaltet werden kann. Es ist auch möglich über entsprechende Leitungsführung und Ventile den Kältemittelkreislauf umzuschalten ohne die Förderrichtung des Kompressors zu ändern.In one embodiment, it may be provided that the conveying direction of the compressor is switchable, so that by controlling the compressor of the Refrigerant circulation can be switched. It is also possible via appropriate wiring and Valves the refrigerant circuit to switch without the conveying direction to change the compressor.
Es ist vorgesehen, dass die Steuervorrichtung den Kältemittelkreislauf für eine bestimmte, vorzugsweise kurze Zeitdauer umschaltet. Die Zeitdauer kann dabei voreinstellbar oder fest vorgegeben sein.It is envisaged that the control device the refrigerant circuit for one switches over a certain, preferably short period of time. The duration can be presettable or fixed.
In einer Ausführung kann der Verdampfer einen Temperatursensor aufweisen, der mit der Steuervorrichtung verbunden ist. So ist es möglich, dass der Kältemittelkreislauf von der Steuervorrichtung so lange umgeschaltet wird, bis der Verdampfer eine vorgegebene Temperatur erreicht hat. So kann ein sicheres Entkeimen des Verdampfers auch bei unterschiedlichen Umgebungstemperaturen gewährleistet werden.In one embodiment, the evaporator a Temperature sensor, which is connected to the control device is. So it is possible that the refrigerant circuit is switched by the control device until the evaporator has reached a predetermined temperature. This is how safe disinfection can be achieved the evaporator even at different ambient temperatures be guaranteed.
Um einen möglichst unterbrechungsfreien Betrieb der Klimaanlage in dem ersten Schaltzustand, d. h. im Kühlbetrieb zu ermöglichen ist normalerweise keine Unterbrechung des Kühlbetriebs vorgesehen. Es ist jedoch möglich, dass die Steuervorrichtung nach einer sehr langen ununterbrochenen Kühlperiode den Kältemittelkreislauf für kurze Zeit umschaltet.In order to be as interruptible as possible the air conditioner in the first switching state, d. H. in cooling mode to enable there is normally no interruption of the cooling operation. It is however possible, that the controller after a very long uninterrupted refrigeration period the refrigerant circuit for a short time Time switches.
In einer vorteilhaften Ausführung ist vorgesehen, dass die Steuervorrichtung den Kühlkreislauf beim Starten des Fahrzeugs umschaltet, um Keime und/oder Sporen die sich während der Standzeit des Fahrzeugs entwickelt haben abzutöten.In an advantageous embodiment provided that the control device, the cooling circuit when starting the Vehicle switches to germs and / or spores during the Lifespan of the vehicle have evolved to kill.
Es ist auch möglich, dass die Steuervorrichtung den Kühlkreislauf beim bei dem Abstellen des Fahrzeugs umschaltet Hierbei werden zwei vorteilhafte Wirkungen erzielt. Zum ersten wird der Verdampfer entkeimt. Zum zweiten wird der Verdampfer zusätzlich auch getrocknet, so dass sich nur wenige Keime und/oder Sporen entwickeln können.It is also possible that the control device the cooling circuit when switching when the vehicle turns off this will be two achieved beneficial effects. First, the evaporator is sterilized. Second, the evaporator is additionally dried, so that only a few germs and / or spores can develop.
Üblicherweise wird der Kompressor durch den Verbrennungsmotor eines Fahrzeugs angetrieben. Um ein Starten des Motors bei abgestelltem Fahrzeug zu vermeiden, kann der Kompressor zusätzlich eine elektrischen Antrieb aufweisen, der den Kompressor bei abgestelltem Verbrennungsmotor antreibt. Es ist auch möglich den Kompressor rein elektrisch anzutreiben, z. B. über einen separaten Elektromotor oder einen in den Kompressor integrierten Antrieb.Usually The compressor is powered by the internal combustion engine of a vehicle driven. To start the engine with the vehicle off To avoid this, the compressor can additionally use an electric drive have, which drives the compressor with the engine stopped. It is also possible to drive the compressor purely electrically, z. B. over a separate electric motor or one integrated into the compressor Drive.
Die erfindungsgemäße Klimaanlage kann vorteilhaft bei Personenkraftwagen oder Nutzfahrzeugen oder Omnibussen eingesetzt werden. Es ist auch möglich, die erfindungsgemäße Klimaanlage bei Fahrzeugen mit alternativen Antrieben oder Elektrofahrzeugen zu verwenden.The air conditioner according to the invention can be advantageous used in passenger cars or commercial vehicles or buses become. It is also possible, the air conditioning system according to the invention Vehicles with alternative drives or electric vehicles use.
