Abstract
Lüftungsanlage mit einem von einem Außenluftstrom beaufschlagten ersten Wärmetauscher, wobei der erste Wärmetauscher ein Luft-Luft-Wärmetauscher ist, in dem ein Abluftstrom aus zu beheizenden Räumen Wärmeenergie auf den Außenluftstrom 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 der Wärmepumpe beaufschlagt ist und der zweite Wärmetauscher (7) in Strömungsrichtung des Kältemittels hinter dem Verflüssiger (5) des Wärmepumpenkreises (3) liegt und der zweite Wärmetauscher (7) durch sensible Wärme des Kältemittels erwärmt wird um den ersten Wärmetauscher (1) reiffrei und/oder eisfrei zu halten.Ventilation system with an acted upon by an outside air flow first heat exchanger, wherein the first heat exchanger is an air-air heat exchanger in which an exhaust air from rooms to be heated transfers heat energy to the outside air flow, characterized in that a second heat exchanger (7) is provided via in which the second heat exchanger (7) is acted upon by the refrigerant of the heat pump and the second heat exchanger (7) in the flow direction of the refrigerant behind the condenser (5) of the heat pump cycle (3 ) and the second heat exchanger (7) is heated by sensible heat of the refrigerant in order to keep the first heat exchanger (1) free from frost and / or ice.
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 The invention relates to a ventilation system with one of a Outside air flow acted upon first heat exchanger, wherein this outside air before a second Heat exchanger is guided by refrigerant a heat pump is flowed through.

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.task The invention is in a ventilation system of the above mentioned type the acted upon by the outside air flow heat exchanger free from frost and ice, without the need for an additional radiator is necessary and without the heat pump cycle must be reversed.
Erfindungsgemäß ist obige Aufgabe durch die Merkmale des kennzeichnenden Teils 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 invention the above object by the features of the characterizing part of the claim 1 solved. This ensures that the first heat exchanger supplied outside air flow preheated in such a way It will not cause a tire or icing of the first Heat exchanger can come. Additional primary energy or an interruption of the heat pump operation are for this purpose not mandatory.
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 is the heat exchanger of the condensed refrigerant the refrigerant circuit of the heat pump is applied, being sensitive heat of the condensed refrigerant is heated. The preheating of the outside airflow takes place by supercooling enthalpy. Their use does not incur any additional costs. Because she does not have a reinforcement the power of the compressor of the heat pump bought become.
