Description
<Desc/Clms Page number 1>
Verfahren zur Luftkonditionierung von verschiedenen, je mit einer Luftbehandlungsvorrichtung versehenen Räumen und Anlage zur Durchführung dieses Verfahrens Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Luftkonditionierung von verschiedenen, je mit einer Luftbehandlungsvorrichtung ver- sehenen Räumen, bei welchem Aussenluft an einer zentralen Stelle vorbehandelt und dann den genannten Behandlungsvorrichtungen zugeführt wird, in welchen diese Aussenluft nach Vermischung mit Luft aus dem jeweiligen Raum den Bedingungen in diesem angepasst wird, und eine Anlage zur Durchführung dieses Verfahrens.
Bei den bisher bekannten Verfahren wurde die eingeführte Aussenluft bis zur Sättigung gekühlt und hat Taupunkttemperatur, sie wurde dann durch ein Leitungssystem zu den verschiedenen Behandlungsvorrichtungen geführt. Die Temperatur dieser Luft war aber unter dem Taupunkt des zu beschickenden Raumes sowie unter dem Taupunkt der die Leitungen umgebenden Luft. Um Tropfenbildung zu vermeiden, war es daher nötig, doppelwandige, mit Isolation versehene Leitungen sowie Ablaufeinrichtungen für die verschiedenen Behandlungsvorrichtungen vorzusehen. Die Kosten solcher Anlagen und die ihrer Wartung wurden dadurch erheblich erhöht.
Dies lässt sich erfindungsgemäss dadurch beheben, dass die eingeführte feuchte Aussenluft derart gekühlt und getrocknet wird, dass ihr Taupunkt unter dem Taupunkt der Luft in den Räumen und unter dem Taupunkt der die Verteilungsleitungen umgebenden Luft liegt, dass diese Aussenluft dann bis annähernd Raumtemperatur vor ihrer Verteilung gewärmt wird, worauf sie in eine Anzahl Behand- Iungsvorrichtungen gelangt, in welchen ihre Temperatur durch Wärmeaustausch auf den gewünschten Wert gebracht wird.
Die erfindungsgemässe Anlage zur Durchführung dieses Verfahrens ist gekennzeichnet durch einen ersten Wärmeaustauscher zur Kühlung und Trocknung der eingeführten Aussenluft, einen zweiten Wärmeaustauscher zur Erwärmung der getrockneten Luft, Leitungen zur Verteilung der erwärmten Luft in eine Anzahl Behandlungsvorrichtungen, in welchen diese Luft mit aus dem zu beschickenden Raum kommender Luft vermischt wird, wobei jede dieser Behandlungsvorrichtungen mit einem eigenen Wärmeaustauscher zur Kühlung der genannten Luftmischung versehen ist.
In der beiliegenden Zeichnung ist ein Ausführungsbeispiel der erfindungsgemässen Anlage schematisch dargestellt, an Hand welchem das erfindungsgemässe Verfahren beispielsweise erläutert wird.
In der Zeichnung bezeichnet 1 den Kompressor einer beispielsweise mit Freon (eingetragene Marke) arbeitenden Kältemaschine, 2 deren Kondensator und 3 und 4 die Verdampfer der Anlage. Die feuchte Aussenluft wird bei 5 eingeführt und im Verdampfer 4 gekühlt und getrocknet. Sie wird dann über den Kondensator 2 und die Leitungen 6 zu den verschiedenen Zimmereinzelbehandlungsvorrichtungen 7 geführt. Die Lufttemperatur wird in diesen Vorrichtungen 7 durch Wärmeaustausch, z. B. mit Wasser, den jeweiligen Zimmerbedingungen angepasst. Das Wasser zur Kühlung kann beispielsweise vom Verdampfer 3 oder aber von einer sonstigen Quelle bezogen werden.
Die bei 5 zugeführte Luft ist im Verdampfer 4 derart gekühlt und getrocknet, dass ihr Taupunkt unter dem Taupunkt der Luft in den zu beschickenden Zimmern und unter dem Taupunkt der die Leitungen 6 umgebenden Luft liegt. Im Kondensator
<Desc/Clms Page number 2>
2 wird die Luft wieder bis annähernd Raumtemperatur .erwärmt, damit keine Kondenswasserbildung mehr auf den Leitungen auftritt. Über die Verteil- leitungen 6 gelangt die Luft in die Vorrichtungen 7, in welchen diese Luft mit Luft aus den jeweiligen Zimmern vermischt wird, worauf die Mischung durch Wärmeaustausch in diesen Vorrichtungen mit dem in den Leitungen 8 zirkulierenden Medium auf die gewünschte Temperatur gekühlt wird.
Es ist nicht unbedingt nötig, eine Kühlmaschine für die Kühlung, Trocknung und Wiedererwärmung der Luft zu verwenden. Die Kühlung könnte mittels kalten Wassers und die Erhitzung mittels heissen Wassers durchgeführt werden.

Method for air conditioning of different rooms each provided with an air treatment device and system for carrying out this method. The present invention relates to a method for air conditioning of different rooms each provided with an air treatment device, in which outside air is pretreated at a central point and then is fed to the treatment devices mentioned, in which this outside air, after mixing with air from the respective room, is adapted to the conditions in this, and a system for carrying out this process.
In the previously known methods, the outside air introduced was cooled to saturation and has dew point temperature, it was then led through a pipe system to the various treatment devices. The temperature of this air was, however, below the dew point of the room to be charged and below the dew point of the air surrounding the pipes. In order to avoid the formation of drops, it was therefore necessary to provide double-walled lines with insulation as well as drainage devices for the various treatment devices. The costs of such systems and their maintenance were thereby increased considerably.
According to the invention, this can be remedied by cooling and drying the introduced moist outside air in such a way that its dew point is below the dew point of the air in the rooms and below the dew point of the air surrounding the distribution lines, so that this outside air is then approximately up to room temperature before it is distributed is heated, whereupon it arrives in a number of treatment devices, in which its temperature is brought to the desired value by heat exchange.
The system according to the invention for carrying out this process is characterized by a first heat exchanger for cooling and drying the outside air introduced, a second heat exchanger for heating the dried air, lines for distributing the heated air in a number of treatment devices in which this air is fed from the Room coming air is mixed, each of these treatment devices is provided with its own heat exchanger for cooling the air mixture mentioned.
In the accompanying drawing, an embodiment of the system according to the invention is shown schematically, on the basis of which the method according to the invention is explained, for example.
In the drawing, 1 denotes the compressor of a refrigerating machine working, for example, with Freon (registered trademark), 2 its condenser, and 3 and 4 the evaporators of the system. The moist outside air is introduced at 5 and cooled in the evaporator 4 and dried. It is then fed via the capacitor 2 and the lines 6 to the various individual room treatment devices 7. The air temperature is in these devices 7 by heat exchange, for. B. with water, adapted to the respective room conditions. The water for cooling can be obtained, for example, from the evaporator 3 or from another source.
The air supplied at 5 is cooled and dried in the evaporator 4 in such a way that its dew point is below the dew point of the air in the rooms to be charged and below the dew point of the air surrounding the lines 6. In the condenser
<Desc / Clms Page number 2>
2 the air is warmed up again to almost room temperature so that no more condensation occurs on the lines. Via the distribution lines 6 the air reaches the devices 7, in which this air is mixed with air from the respective rooms, whereupon the mixture is cooled to the desired temperature by heat exchange in these devices with the medium circulating in the lines 8.
It is not absolutely necessary to use a cooling machine for cooling, drying and reheating the air. The cooling could be carried out with cold water and the heating with hot water.
