Abstract
Bezeichnung Dreistufiges Verfahren bzw. Apparat zur Absenkung der Lufttemperatur vor kombinierten, so wie separaten Frei- und Verflüssigungskühlern in Kälte-, Kühl- und Klimaanlagen, wovon der erste Wärmetauscher als adiabatischer Wärmetauscher ausgeführt ist.KurzfassungTechnische AufgabenKombinierte Frei- und Verflüssigungskühler sind bisher in ihrer Leistung stark abhängig von der Ansaugtemperatur. Hohe Ansaugtemperaturen sind nur teilweise durch großen apparativen Aufwand und hohe energetische Aufwände kompensierbar. Das neue Verfahren soll am Freikühler, so wie auch am Verflüssiger Temperaturen unter der Ansaugtemperatur ermöglichen und so die Energieeffizienz zu bestehenden Verfahren steigern und Ressourcen einsparen. Hier wird die Temperaturdifferenz zwischen Trockenkugel und Feuchtkugeltemperatur ausgenutzt.LösungEin adiabatischer Wärmetauscher wird in Reihe zum kombinierten Frei- und Verflüssigungskühler geschaltet, so dass die Ansaugtemperatur vor dem Freikühler und/oder Verflüssiger bis auf die Feuchtkugeltemperatur absinkt.AnwendungsgebietDie Effizienz des Frei- und Verflüssigungskühlers wird durch das Verfahren erhöht und der Einsatz für den Freikühlbetrieb auch bei höheren Ansaugtemperaturen zu den Sekundärmedientemperaturen ermöglicht, was bisher in einem Apparat nicht möglich ist. Der Frei-, wie auch der Verflüssigungskühler kann teilweise kleiner ausgeführt werden. So findet das neue Verfahren in den Bereichen der Kälte-, Kühl- und Klimatechnik Anwendung.Designation Three-stage process or apparatus for lowering the air temperature in front of combined, as well as separate free and condenser coolers in refrigeration, cooling and air conditioning systems, of which the first heat exchanger is designed as an adiabatic heat exchanger. Summary Technical tasks Combined free and condenser coolers have so far been in their performance strongly dependent on the intake temperature. High intake temperatures can only partially be compensated for by large expenditure on equipment and high expenditure on energy. The new process should enable temperatures below the intake temperature at the free cooler and at the condenser, thus increasing the energy efficiency compared to existing processes and saving resources. Here, the temperature difference between dry bulb and wet bulb temperature is used.SolutionAn adiabatic heat exchanger is connected in series to the combined free cooler and condenser so that the intake temperature before the free cooler and/or condenser drops to the wet bulb temperature.ApplicationThe efficiency of the free cooler and condenser is increased by increases the process and enables use for free cooling operation even at higher intake temperatures than the secondary medium temperatures, which was previously not possible in an apparatus. The free cooler as well as the liquefaction cooler can sometimes be made smaller. The new process is used in the areas of refrigeration, refrigeration and air conditioning.
Description
- - Die Ansaugluft (Primärluft) durchströmt den adiabatischen Wärmetauscher (1)- The intake air (primary air) flows through the adiabatic heat exchanger (1)
- - Der adiabatische Wärmetauscher wird von oben mit Wasser beaufschlagt- The adiabatic heat exchanger is charged with water from above
- - Das Wasser auf der Oberfläche des adiabatischen Wärmetauschers nimmt zum Verdampfen Wärme aus der Primärluft auf. Die Primärluft wird von der Trockenkugeltemperatur bis zur Feuchtkugeltemperatur abgekühlt und befeuchtet.- The water on the surface of the adiabatic heat exchanger absorbs heat from the primary air to evaporate. The primary air is cooled and humidified from dry bulb temperature to wet bulb temperature.
- - Das überschüssige Wasser, wird in einer Tropfwanne (2) aufgefangen und dem Kreislauf mit Hilfe einer Pumpe (3) wieder zur Verfügung gestellt.- The excess water is collected in a drip tray (2) and made available again for the cycle with the help of a pump (3).
- - Die abgekühlte Primärluft wird nach dem adiabatischen Wärmetauscher zum kombinierten Frei- und Verflüssigungswärmetauscher (4) geführt.- After the adiabatic heat exchanger, the cooled primary air is routed to the combined free and condensing heat exchanger (4).
- - Im ersten Teil des kombinierten Frei- und Verflüssigungskühlers (4), dem Freikühler (4.1), gibt das Primärkühlmedium (Flüssigkeit, Wasser, Gas, etc.) Wärme an die Primärluft ab.- In the first part of the combined free cooler and condenser (4), the free cooler (4.1), the primary cooling medium (liquid, water, gas, etc.) transfers heat to the primary air.
- - Im zweiten Teil des kombinierten Frei- und Verflüssigers (4.2), dem Verflüssiger, gibt das Sekundärmedium (Kältemittel) Wärme an die Primärluft ab und ändert seinen Aggregatzustand in flüssig.- In the second part of the combined condenser and condenser (4.2), the condenser, the secondary medium (refrigerant) gives off heat to the primary air and changes its physical state to liquid.
- - Sollte die Primärluft kalt genug sein, kann zeitweise auf die adiabatische Kühlung verzichtet werden und die Primärluft unbehandelt am Frei- und Verflüssigungskühler ausreichend Wärme aufnehmen. Hierzu können optional Bypassorgane (5) angebracht werden.- If the primary air is cold enough, the adiabatic cooling can be temporarily dispensed with and the primary air can absorb sufficient heat untreated at the free and condenser cooler. Optional bypass elements (5) can be attached for this purpose.

Das dreistufige Verfahren zur Wärmeübertragung besteht aus dem adiabatischen Wärmetauscher, Freikühler, Verflüssiger und Ventilator.The three-stage heat transfer process consists of the adiabatic heat exchanger, free cooler, condenser and fan.
Hinzu kommen noch die Bauteile einer klassischen Kälteanlage für den Verflüssigerkreislauf, wie Kältemittelverdichter, Ventilator, Einspritzventil, Verdampfer, Rohrleitungen und Steuer- und Regelorgane. Die Kälteanlage kann im gleichen Gehäuse wie das dreistufige Verfahren untergebracht werden oder als separate Einheit ausgeführt sein.In addition, there are the components of a classic refrigeration system for the condenser circuit, such as refrigerant compressor, fan, injection valve, evaporator, pipes and control and regulating devices. The refrigeration system can be housed in the same housing as the three-stage process, or it can be designed as a separate unit.
