Description
Die Erfindung betrifft eine Einrichtung gemäss dem Oberbegriff des ersten Patentanspruches wie sie aus Dokument DE 3415881 bekannt ist.The invention relates to a device according to the preamble of the first claim as known from document DE 3415881.
Derartige Einrichtungen werden insbesondere zum Trocknen von Wäsche in Trocknungsräumen in Mehrfamilienhäusern verwendet.Such devices are used in particular for drying Laundry used in drying rooms in apartment buildings.
Die heute verwendeten Luftentfeuchter sind jeweils meistens mit Kältekompressor, Verdampfer mit Ventilator, Luftkondensator, Kältekreislauf, Hygrostaten sowie mit einem Kondenswasserauffangtank ausgestattet. Die Stromzufuhr erfolgt über einen Netzanschluss, z.B. an 220 Volt Wechselspannung.The dehumidifiers used today are mostly with refrigeration compressor, evaporator with fan, air condenser, Refrigeration circuit, hygrostats and with a condensate collection tank fitted. The power is supplied via a mains connection, e.g. to 220 volts AC.
Luftentfeuchter dieser Art sind mit dem Nachteil behaftet, dass die Kondensations-Abwärme unabhängig von der Raumtemperatur bzw. den Jahreszeiten stets an die zirkulierende Umgebungsluft abgegeben wird, weshalb solche Ausführungen unwirtschaftlich sind und deshalb in der Umgangssprache als "Stromfresser" bezeichnet werden.Dehumidifiers of this type have the disadvantage that that the condensation waste heat regardless of the room temperature or the seasons always in the circulating ambient air is delivered, which is why such statements are uneconomical are and therefore in colloquial language as "electricity guzzlers" be designated.
Aufgabe der vorliegenden Erfindung ist die Schaffung einer Einrichtung, welche die Nachteile herkömmlicher Ausführungen nicht aufweist, und bei der die Abgabe von Kondensationswärme je nach Bedarf an die Umgebungsluft möglich ist, oder dass diese Wärme alternativ benutzt werden kann. Ferner soll die Einrichtung in Anlagen derjenigen Art verwendet werden können, welche in EP-B-0 227 051 beschrieben sind.The object of the present invention is to create a Device that has the disadvantages of conventional designs does not have, and in which the release of condensation heat depending on the need for the ambient air, or that this heat can alternatively be used. Furthermore, the Can be used in facilities of the type which are described in EP-B-0 227 051.
Diese Aufgabe ist erfindungsgemäss im Kennzeichnungsteil des ersten Anspruches gelöst.This object is according to the identification part of the first claim solved.
Ausführungsformen sind in den abhängigen Ansprüchen umschrieben. Embodiments are described in the dependent claims.
Die beschriebene Einrichtung ist im Gegensatz zu den herkömmlichen Ausführungen mit einem Wasserkondensator ausgestattet, der primärseitig in einen Kältekreislauf eingebunden und sekundärseitig über eine Ladevorrichtung mit einem Speicher bzw. Warmwasserspeicher verbunden ist. Ferner ist der Kältekreislauf mit einem Magnet-Durchgangs- oder Dreiwegventil versehen.The device described is in contrast to the conventional Versions equipped with a water condenser, the primary side is integrated into a refrigeration cycle and the secondary side via a charger with a memory or hot water tank is connected. Furthermore, the refrigeration cycle with a magnetic two-way or three-way valve Mistake.
Ein Einbau der beiden Aggregate, d.h. Wasserkondensator und Magnetventil, in den Kältekreislauf, erlaubt eine alternative Nutzung, z.B. zur Erwärmung des Warmwasserspeichers zum Nulltarif.Installation of the two units, i.e. Water condenser and Solenoid valve, in the refrigeration cycle, allows an alternative Usage, e.g. for heating the hot water tank at no cost.
Über die Umschaltung des Dreiweg- oder Durchgangsventils wird über die Nutzniessung der Kondensationsabwärme bestimmt. Die Magnetventil-Schaltung ist u.a. von den folgenden Faktoren abhängig:
- Wassertemperatur im Warmwasserspeicher
- Raumtemperatur
- Relative Luftfeuchtigkeit im Trocknungsraum
- Water temperature in the hot water tank
- Room temperature
- Relative humidity in the drying room
Die beschriebene Einrichtung besitzt gegenüber herkömmlichen Ausführungen folgende Vorteile:The device described has compared to conventional The following advantages:
Nachfolgend wird ein Ausführungsbeispiel der erfindungsgemässen Einrichtung anhand eines Prinzipschemas näher erläutert, das einen Kältekreislauf mit integriertem Wasserkondensator darstellt.Below is an embodiment of the invention Establishment explained in more detail using a basic scheme, the one refrigeration cycle with integrated water condenser represents.
Das Schema zeigt zwei parallel geschaltete Kompressoren 1,2,
einen Luftverdampfer 3, einen Ventilator 4, einen Luftkondensator
5, ein Drossel- und Expansionsventil 6, einen Wasserkondensator
7 mit Leitungen 8,9 sowie Kältemittelleitungen 10
mit Magnet-Durchgangsventil 11, Hygrostat 12, Wasserthermostat
13, Raumthermostat 14 und einen Wärmekonvektor 15. The diagram shows two
Nach der Einschaltung der Einrichtung werden die beiden Kompressoren
1,2 gestaffelt angelassen. Wenn das Magnet-Durchgangsventil
11 offen ist, erfolgt die Wärmeabgabe an die
Raumluft, wobei die Funktionsweise derjenigen der heute üblichen
Luftentfeuchtungsgeräten entspricht.After switching on the device, the two
Die Einrichtung bzw. der Luftentfeuchter ist mit einer Warmwasser-Vorzugssteuerung
versehen, wobei das Magnet-Durchgangsventil
11 schliesst, sofern der Warmwasserspeicher Wärme
verlangt. Das Kältemittel strömt primärseitig durch den
Wasserkondensator 7 und erwärmt das sekundärseitig in den
Leitungen 8,9 zirkulierende Wasser.The device or the dehumidifier is equipped with a hot water priority control
provided, the magnetic two-
Falls der Speicher erwärmt ist und ihm somit keine Kondensationswärme
zugeführt werden kann, wird das Magnetventil 11
geöffnet. Die Wärmeabgabe erfolgt in diesem Falle über den
Luftkondensator 5 bis die Einrichtung bzw. der Luftentfeuchter
automatisch via Hygrostat 12 oder manuell über den Geräte-Hauptschalter
ausgeschaltet wird.If the storage tank is warmed up and therefore no condensation heat
can be supplied, the solenoid valve 11th
open. In this case, the heat is emitted via the
Falls die Temperatur des Speichers unter den Sollwert sinkt, wird die Einrichtung bzw. der Luftentfeuchter sofort eingeschaltet, und zwar unabhängig von der jeweiligen Schalterstellung am Geräte-Hauptschalter.If the temperature of the storage tank falls below the setpoint, the device or the dehumidifier is switched on immediately, regardless of the switch position on the main device switch.
An der Einrichtung bzw. am Luftentfeuchter kann der Raumthermostat
14 als Schutz gegen eine mögliche Unterkühlung angeschlossen
werden. Falls die Temperatur unter den gewählten
Sollwert fällt, öffnet das Magnetventil 11 im Kältekreislauf
automatisch. Das Kältemittel wird durch den Luftkondensator
geleitet und gibt Kondensationsabwärme an die Raumluft ab.
Die Warmwassererwärmung über den Wasserkondensator 7 wird
solange unterdrückt, bis die Raumtemperatur den Sollwert
erreicht hat. Falls dieser überschritten wird, schliesst das
Magnetventil 11 und die Kondensationswärme wird an den
Wasserkondensator 7 abgegeben. The room thermostat can be installed on the device or on the
Der Wärmekonvektor 15 ist im Kältekreis im Luftstrom nach dem
Verdampfer 3 eingebaut und dient zur Unterkühlung des Kondensats,
wobei er die wichtige Aufgabe hat, die durch den Verdampfer
3 abgekühlte Luft mit dem Kondensat wieder zu erwärmen.
Durch diese Massnahme kann eine Abkühlung oder Unterkühlung
des Raumes verhindert werden, was insbesondere bei Anlagen in
geschlossenen Räumen von grösster Bedeutung ist.
Der grösstmögliche Nutzen der Einrichtung liegt dann vor, wenn Wäschetrocknung und Warmwassererwärmung gleichzeitig erfolgen, wobei die Wirtschaftlichkeit mit erhöhter Betriebsdauer zunimmt.The greatest possible benefit of the facility is then if laundry drying and hot water heating take place at the same time, the economy with increased service life increases.
