Abstract
Mit der Lüftungsbox kann der Einsatzbereich der konventionellen Sole/Wasser-Wasser/Wasser-Wärmepumpe einfach erweitert werden. Im Niedrigenergiehaus oder im Passivhaus werden Lüftungssystem dringend erforderlich. Parallel dazu existiert mitunter im Sommer die Gefahr der Überhitzung bei großen Glasfassaden im Südbereich. Die Planung der kontrollierten Lüftung mit Wärmerückgewinnung ist deutlich einfacher als bei zentralen Lüftungssystemen. Zusätzlich wird ohne Mehraufwand die Kühlfunktion integriert. Gegenüber Wärmepumpen ohne Lüftungsbox ist eine effizientere Energieausnutzung zu erwarten, da die Soletemperatur ganzjährig höher ist als bei Systemen ohne Lüftungsbox. Die Kühlung selbst funktioniert auch ohne Wärmepumpe, da das Erdreich mit 12 DEG C im Sommer ausreichend kühl ist. Die Funktion der Wärmerückgewinnung und Kühlung ist unabhängig von der Anschlußleistung der Wärmepumpe und dem Luftdurchsatz durch die Lüftungsbox gewährleistet.With the ventilation box, the area of application of the conventional brine / water-water / water heat pump can be easily expanded. Ventilation systems are urgently required in low-energy houses or passive houses. At the same time, there is sometimes a risk of overheating in the south with large glass facades in summer. The planning of controlled ventilation with heat recovery is much easier than with central ventilation systems. In addition, the cooling function is integrated without additional effort. Compared to heat pumps without a ventilation box, more efficient energy utilization can be expected since the brine temperature is higher all year round than in systems without a ventilation box. The cooling itself works even without a heat pump, since the ground is sufficiently cool at 12 ° C in summer. The function of heat recovery and cooling is guaranteed regardless of the connected load of the heat pump and the air flow through the ventilation box.
Description
Aus der Literatur sind zahlreiche Beispiele bekannt, wie Wärmepumpen für Air Condition (Heizen und Kühlen) verwendet werden. In den meisten Fällen geschieht das durch ein Vierwege-Ventil (WO 90/02300/DE 33 13 407), das den eigentlichen Verdampfer bzw. Verflüssiger in der Funktion tauscht. Das geschieht direkt im Kältemittelkreis. Eine aufwendigere Lösung zeigt wie durch eine Spezialwärmetauscher (zwei Tauscher für Heizen bzw. Kühlen von Luft) im Verbindung mit einem Boiler, Heizung, Kühlung und Warmwasserbereitung integriert werden. Es werden mehrere Ventile benötigt. In alten dargestellten Fällen wurden dabei mehrere Komponenten miteinander verrohrt. Der Platzbedarf ist entsprechend hoch (US 4,299,098). Eine Abluftwärmerückgewinnung ist in Verbindung mit einer Kühlfunktion nicht bekannt. Die Firma Stiebel Eltron, sowie einige schwedische Firmen bieten serienmäßig Abluftwärmepumpen an. Die Kaltluftseite des Agregates ist jedoch nicht für Kühlung von Wohnräumen geplant. Folgende Erfindung zeigt, wie einfach die Funktion der Wärmerückgewinnung aus der Abluft zur Funktion der Kühlung von Wohnräumen umgekehrt werden kann.Numerous examples are known from the literature, such as heat pumps for air Condition (heating and cooling) can be used. Happens in most cases by a four-way valve (WO 90/02300 / DE 33 13 407), which the actual Function of evaporator or condenser. This happens directly in the Refrigerant circuit. A more elaborate solution shows like one Special heat exchanger (two exchangers for heating or cooling air) in the Connection with a boiler, heating, cooling and water heating integrated become. Several valves are required. In the old cases presented piping several components together. The space requirement is corresponding high (US 4,299,098). An exhaust air heat recovery is in connection with a Cooling function not known. The Stiebel Eltron company, as well as some Swedish ones Companies offer exhaust air heat pumps as standard. The cold air side of the unit is however not planned for cooling living spaces. The following invention shows how simply the function of heat recovery from the exhaust air to the function of Cooling of living spaces can be reversed.
Folgende Erfindung zeigt wie zusätzlich zur Wärmerückgewinnung aus der Abluft und deren Nutzung für Heizung und Warmwasserbereitung zusätzlich ein Wärmespeicher (Erde, Wasser) aufgeladen wird. Besonders die Aufladung eines Wärmespeichers (vorzugsweise das Erdreich) im Sommer, ermöglicht es, in Verbindung mit einem Sole- oder Wasserkreis einfach Kaltluft zu erzeugen, die für die Kühlung von Wohnräumen auch ohne ständiges Arbeiten einer Wärmepumpeneinheit verwendet werden kann.The following invention shows how in addition to the heat recovery from the exhaust air and their use for heating and hot water preparation additionally a heat storage (Earth, water) is charged. Especially the charging of a heat store (preferably the soil) in summer, allows it to be combined with a Brine or water circuit easily generate cold air that is used for cooling Living rooms also used without the constant work of a heat pump unit can be.
Voraussetzung für diese Kühlfunktion ist ein Wärmespeicher, der immer kälter als die Außenluft im Sommer ist. Praktisch wird dies mit dem Solekreis einer Wärmepumpe realisiert, indem die Wärme bzw. die Kälte des Erdreiches (ca. 10°C) zum Heizen oder Kühlen von Luft genutzt wird. Da Niedrigenergiehäuser ein Lüftungssystem benötigen, realisiert die Erfindung eine ganzjährige kontrollierte Lüftung mit Abluftenergienutzung im Wohnbereich, sowie im Sommer eine Kühlung der Zuluft.A prerequisite for this cooling function is a heat accumulator that is always colder than that Outside air is summer. This becomes practical with the brine circuit of a heat pump realized by the heat or the cold of the soil (approx. 10 ° C) for heating or cooling air is used. Because low-energy houses have a ventilation system need, the invention realizes a year-round controlled ventilation Exhaust air use in the living area and cooling of the supply air in summer.
Die Kühlung wird über die Funktionsumkehr des Luft/Wasserwärmetauscher (1) realisiert. Hier wird im Normalfall verbrauchte Abluft zentral abgesaugt und Frischluft über Zuluftventile in den Außenwänden der Wohnräume dezentral zugeführt. Der hierfür benötigte Ventilator (2) verfügt über Drehzahlsteuerung und Drehrichtungsumkehr (3). Aus dieser Drehrichtungsumkehr ergibt sich die Funktionsumkehr. Das Lüftungssystem wird nach der Drehrichtungsumkehr zur Zuluftanlage. Der Solekreis (4) kühlt die warme Außenluft ab. Es entsteht kalte Zuluft, die zu Kühlzwecken in die Räume und danach über die Zuluftelemente nach draußen strömt.Cooling is achieved by reversing the function of the air / water heat exchanger ( 1 ). In this case, used exhaust air is normally extracted centrally and fresh air is supplied decentrally via supply air valves in the outer walls of the living rooms. The fan ( 2 ) required for this has speed control and reversal of the direction of rotation ( 3 ). The function reversal results from this reversal of the direction of rotation. After the direction of rotation is reversed, the ventilation system becomes a supply air system. The brine circuit ( 4 ) cools the warm outside air. Cold supply air is created, which flows into the rooms for cooling purposes and then flows outside via the supply air elements.
