Abstract
Lüftungsanlage mit einem von einem Außenluftstrom (AU) beaufschlagten ersten Wärmetauscher (1), wobei der erste Wärmetauscher (1) ein Luft-Luft-Wärmetauscher ist, in dem ein Abluftstrom aus zu beheizenden Räumen Wärmeenergie auf den Außenluftstrom (AU) überträgt, dadurch gekennzeichnet, dass ein zweiter Wärmetauscher (7) vorgesehen ist, über den der dem ersten Wärmetauscher (1) zugeführte Außenluftstrom (AU) geführt ist, wobei der zweite Wärmetauscher (7) vom Kältemittel einer Wärmepumpe beaufschlagt ist, um den ersten Wärmetauscher (1) reiffrei und/oder eisfrei zu halten.Ventilation system with one of an outside air flow (AU) acted upon first heat exchanger (1), wherein the first heat exchanger (1) is an air-air heat exchanger in which an exhaust air stream from rooms to be heated transfers heat energy to the outside air flow (AU), characterized in that a second heat exchanger (7) is provided, via which the outside air flow (AU) fed to the first heat exchanger (1) is guided, wherein the second heat exchanger (7) is acted upon by the refrigerant of a heat pump, around the first heat exchanger (1) free of tires and / or ice-free.
Description
Die Erfindung betrifft eine Lüftungsanlage mit einem von einem Außenluftstrom beaufschlagten ersten Wärmetauscher, wobei diese Außenluft vorher über einen zweiten Wärmetauscher geführt ist, der von Kältemittel einer Wärmepumpe durchflossen ist.The invention relates to a ventilation system with an acted upon by an outside air flow first heat exchanger, said outside air is previously passed through a second heat exchanger, which is traversed by refrigerant of a heat pump.

Aufgabe der Erfindung ist es, bei einer Lüftungsanlage der eingangs genannten Art den vom Außenluftstrom beaufschlagten Wärmetauscher reiffrei und eisfrei zu halten, ohne dass ein zusätzlicher Heizkörper nötig ist und ohne dass der Wärmepumpenkreislauf umgekehrt werden muss.The object of the invention is to keep in a ventilation system of the type mentioned acted upon by the outside air flow heat exchanger free of frost and ice, without an additional radiator is needed and without the heat pump cycle must be reversed.
Erfindungsgemäß ist obige Aufgabe durch die Merkmale des des Anspruchs 1 gelöst. Dadurch ist erreicht, dass der dem ersten Wärmetauscher zugeführte Außenluftstrom derart vorerwärmt wird, dass es nicht zu einer Bereifung oder Vereisung des ersten Wärmetauschers kommen kann. Zusätzliche Primärenergie oder eine Unterbrechung des Wärmepumpenbetriebs sind hierfür nicht erforderlich.According to the above object is achieved by the features of claim 1. It is thereby achieved that the outside air flow supplied to the first heat exchanger is preheated in such a way that it can not lead to a tire or icing of the first heat exchanger. Additional primary energy or interruption of heat pump operation is not required.
Vorzugsweise ist der Wärmetauscher vom kondensierten Kältemittel des Kältemittelkreises der Wärmepumpe beaufschlagt, wobei er durch sensible Wärme des kondensierten Kältemittels erwärmt wird. Die Vorerwärmung des Außenluftstroms erfolgt dabei durch Unterkühlungsenthalpie. Deren Nutzung verursacht keine Zusatzkosten. Denn sie muss nicht mit einer Verstärkung der Aufnahmeleistung des Verdichters der Wärmepumpe erkauft werden.Preferably, the heat exchanger is acted upon by the condensed refrigerant of the refrigerant circuit of the heat pump, wherein it is heated by sensible heat of the condensed refrigerant. The preheating of the outside air flow takes place by supercooling enthalpy. Their use causes no additional costs. Because it does not have to be bought with an increase in the input power of the compressor of the heat pump.
