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
Switching over the three-way or two-way valve determines the heat of condensation waste. The solenoid valve circuit depends, among other things, on the following factors:
  • 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 compressors 1, 2 connected in parallel, an air evaporator 3, a fan 4, an air condenser 5, a throttle and expansion valve 6, a water condenser 7 with lines 8.9 and refrigerant lines 10 with magnetic 2-way valve 11, hygrostat 12, water thermostat 13, room thermostat 14 and a heat convector 15.

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 compressors 1,2 staggered. If the solenoid two-way valve 11 is open, the heat is released to the Indoor air, the mode of operation of which is common today Dehumidifiers corresponds.

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-way valve 11 closes if the hot water tank heats up demands. The refrigerant flows through the primary Water condenser 7 and heats the secondary side in the Pipes 8.9 circulating water.

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 Air condenser 5 to the device or the dehumidifier automatically via Hygrostat 12 or manually via the main switch is turned off.

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 dehumidifier 14 connected as protection against possible hypothermia become. If the temperature is below the selected If the setpoint falls, the solenoid valve 11 opens in the refrigeration cycle automatically. The refrigerant is through the air condenser conducts and releases condensation heat into the room air. The hot water heating via the water condenser 7 is suppressed until the room temperature reaches the setpoint has reached. If this is exceeded, this closes Solenoid valve 11 and the heat of condensation is the Water condenser 7 delivered.

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.

  • a) Die Einrichtung ist mit zwei Kompressoren ausgestattet, die gestaffelt zum Einatz kommen, so dass die Anlaufströme im Vergleich zur Variante mit nur einem Kompressor sehr niedrig ist. Die Betriebssicherheit wird bei einem 220 V Netzanschluss durch dieses Verfahren stark erhöht. Sicherungsausfälle wegen Überlastung des Netzanschlusses werden gänzlich eliminiert. Die Kompressoren können zudem grösser dimensioniert werden und die Gesamtleistung der Einrichtung wird dadurch erhöht.
  • b) Die Einrichtung kann die Kondensationswärme wahlweise an die Raumluft oder alternativ an ein anderes Medium (z.B. Wasserkreislauf zur Erwärmung des Warmwassers oder zu Heizzwecken abgeben.
  • c) Verlangt der Wasserthermostat Wärme, wird die Einrichtung eingeschaltet. Das Dreiweg- oder Durchgangsmagnetventil im Kältekreislauf leitet das Kältemittel um vom Luft- auf den Wasserkondensator. Das Wasser erwärmt sich und gleichzeitig wird die Raumluft im Verdampfer entfeuchtet.
  • d) Wenn die Wassertemperatur im Speicher den Sollwert erreicht hat, schaltet das Dreiweg- oder Durchgangs-Magnetventil vom Wasser auf den Luftkondensator. Die Kondensations-Abwärme wird, bis die Einrichtung ausschaltet oder der am Hygrostat vorgegebene Luftfeuchtigkeitswert erreicht ist, an die Raumluft abgegeben.
  • e) Falls die Einrichtung in erster Linie zur Entfeuchtung eingeschaltet und gleichzeitig Warmwasser gezapft wird, erfolgt die Nacherwärmung des Warmwassers während des Entfeuchtungsablaufs zum Nulltarif. Die Kondensations-Abwärme wird vollumfänglich an das Warmwasser abgegeben.
  • The heat convector 15 is installed in the cooling circuit in the air flow after the evaporator 3 and serves to supercool the condensate, with the important task of reheating the air cooled by the evaporator 3 with the condensate. This measure can prevent the room from cooling or undercooling, which is of the greatest importance, especially for systems in closed rooms.
  • a) The device is equipped with two compressors that are used in a staggered manner so that the starting currents are very low compared to the variant with only one compressor. With a 220 V mains connection, operational safety is greatly increased by this procedure. Fuse failures due to overloading the mains connection are completely eliminated. The compressors can also be dimensioned larger and the overall performance of the device is increased.
  • b) The device can either give off the condensation heat to the room air or alternatively to another medium (e.g. water circuit for heating the hot water or for heating purposes).
  • c) If the water thermostat requires heat, the device is switched on. The three-way or straight-way solenoid valve in the refrigeration circuit redirects the refrigerant from the air to the water condenser. The water heats up and at the same time the room air in the evaporator is dehumidified.
  • d) When the water temperature in the storage tank has reached the setpoint, the three-way or two-way solenoid valve switches from the water to the air condenser. The waste heat from condensation is released into the room air until the device switches off or the humidity value specified on the hygrostat is reached.
  • e) If the device is primarily switched on for dehumidification and hot water is tapped at the same time, the hot water is reheated during the dehumidification process at no cost. The condensation waste heat is completely released to the hot water.
  • 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.
