Abstract

The combined cooling system and humidifier uses water at a temp. of 0.007 bar as the cooling medium, and for indirect cooling of air in the air-conditioning system. The water is caused to boil by bringing it to a temp. of + 2 degrees C via a heat exchanger (13) immersed in the water bath (4) supplied with water at 6 degrees C. The heat exchanger is fed to an air cooling device (15), with the water evaporation used for bringing it back to 6 degrees C. The cold water vapour remains at a pressure of 0.007 bar for use in humidifying the air in the air-conditioning system as required. ADVANTAGE - Provides substantial saving in electrical energy compared to two separate systems for cooling and air-humidifying.

Description

Die Hochvakuumpumpe 1 erzeugt im Verdampfer 2 einen Unterdruck von 0,007 bar, was einer Verdampfungstemperatur von plus 2 Grad Celsius entspricht. Ein Thermostat 7 überwacht diese Temperatur und schaltet entsprechend die Vakuumpumpe. Dadurch entsteht ein Wasserbad 4 von plus 2 Grad Celsius. In diesem Wasserbad befindet sich ein Wärmetauscher 13, der das Wasser zum Kochen bringt. Ein konventioneller Luftkühler in dem Klimaanlage nimmt die Wärmeenergie der Luft auf und erwärmt das sich im Wasserkreislauf 26 befindliche Wasser auf ca. 12 Grad C. auf. Das erwärme Wasser gelangt wieder in den Wärme­ tauscher 13 und wird auf ca. 6 Grad C. abgekühlt. Eine Umwälzpumpe 14 fördert das Kaltwasser wieder in den Luftkühler 15. Der Kreislauf beginnt von vorn, die Zu­ lufttemperatur der Klimaanlage wird dabei auf Zulufttemp. abgekühlt.The high-vacuum pump 1 generates a negative pressure of 0.007 bar in the evaporator 2 , which corresponds to an evaporation temperature of plus 2 degrees Celsius. A thermostat 7 monitors this temperature and switches the vacuum pump accordingly. This creates a water bath 4 of plus 2 degrees Celsius. In this water bath there is a heat exchanger 13 which brings the water to a boil. A conventional air cooler in the air conditioning system absorbs the thermal energy of the air and heats the water in the water circuit 26 to approximately 12 degrees C. The heated water returns to the heat exchanger 13 and is cooled to approx. 6 degrees C. A circulation pump 14 conveys the cold water back into the air cooler 15 . The cycle begins again, the air temperature of the air conditioning system is set to supply air temp. cooled down.

Durch das Verdampfen des Wassers 4 im Verdampfer 2 senkt sich der Wasserspiegel, was vom Niveauregler 10 erfaßt wird. Diener läßt das Einlaßmagnetventil 11 öffnen und Frischwasser gelangt in den Verdampfer. Ein Tropfenabscheider 3 verhindert dabei, daß die Vakuum­ pumpe 1 vor Flüssigkeitsschlägen geschützt wird. Der Schwimmerschalter 6 verhindert ein Überfüllen des Verdampfers 2. Durch das Ventil 12 kann die Wasser­ zufuhr manuell unterbrochen werden. Durch das ständige Verdampfen von reinem Wasserdampf bleiben die Reststoffe im Wasserbad 4, das Wasser dickt mit der Zeit ein. Um diese Eindickung zu vermeiden, wird zyklisch das Wasser über ein Abschlämmventil 8 abgelassen. Um eine Verkalkung des Wärmetauschers 13 zu vermeiden wird in der Verdampfer ein auswechselbarer Kalksack 5 einge­ baut, der in bestimmten Abständen ausgetauscht werden muß. Der kalte Wasserdampf gelangt über ein Rückschlag­ ventil 22 und der Vakuumpumpe in den Druckstutzen der unter Atmosphärendruck steht ( 1013 mbar ).Evaporation of the water 4 in the evaporator 2 lowers the water level, which is detected by the level controller 10 . Diener has the inlet solenoid valve 11 open and fresh water gets into the evaporator. A droplet separator 3 prevents the vacuum pump 1 from being protected from liquid hammer. The float switch 6 prevents the evaporator 2 from overfilling. Through the valve 12 , the water supply can be interrupted manually. Due to the constant evaporation of pure water vapor, the residues remain in the water bath 4 , the water thickens over time. In order to avoid this thickening, the water is drained cyclically via a drain valve 8 . In order to avoid calcification of the heat exchanger 13 , an interchangeable lime sack 5 is built into the evaporator, which must be replaced at certain intervals. The cold water vapor passes through a check valve 22 and the vacuum pump into the pressure port which is under atmospheric pressure (1013 mbar).

Wird vom Hygrostaten der Klimaanlage Feuchte verlagt, wird der kalte Wasserdampf über ein Dreiwegeventil 23 in die Befeuchterkammer oder in den Zuluftkanal ein­ geleitet. Wird keine Befeuchtung verlangt, wird der Dampf ins Freie oder in die Umgebung geleitet 19. If moisture is expelled from the hygrostat of the air conditioning system, the cold water vapor is passed through a three-way valve 23 into the humidifier chamber or into the supply air duct. If no humidification is required, the steam is led outside or into the environment 19 .

Am oberen Teil des Behälters wird eine Hochvakuumpumpe angeschlossen, die über eine Membrane arbeitet und wasserdampfunempfindlich ist. Ein Rückschlagventil ver­ hindert einen Druckausgleich bei Stillstand der Vakuum­ pumpe. Am Druckstutzen der Vakuumpumpe wird ein Dreiwege­ ventil eingebaut. Wird von der Klimaanlage der Befeuch­ tungsbetrieb gefordert, schaltet ein Hygrostat das Drei­ wegeventil so, daß der kalte Wasserdampf in die Befeuchter­ kammer der Klimaanlage geleitet wird.At the top of the tank is a high vacuum pump connected, which works via a membrane and is insensitive to water vapor. A check valve ver prevents pressure equalization when the vacuum stops pump. There is a three-way connection at the pressure port of the vacuum pump valve installed. The humidifier is from the air conditioning required, a hygrostat switches the three directional control valve so that the cold water vapor enters the humidifier Chamber of the air conditioning system is directed.
