Abstract

An air conditioning system has a heat recovery system with two cross-flow heat exchangers and a contra-flow heat exchanger.

Description

Die Erfindung ist zuzuordnen dem Bereich der kontrollierten Wohnraumlüftung mit Wärmerückgewinnung. Die dort eingesetzten Lüftungsgeräte arbeiten vorwiegend mit Kreuzstrom-, Kreuzgegenstrom- und Gegenstromwärmetauschern. Diese Wärmetauscher bestehen aus Metall (z.B. Alu) oder Kunststoff (z.B. PVC). Ihre Aufgabe besteht darin, nur die Wärmeinhalte der Abluft auf die Zuluft zu übertragen. Die Luftarten Zuluft und Abluft sollen sich nicht vermischen. Entsprechende Vorschriften bei der bauaufsichtlichen Zulassung geben hier Werte vor.The The invention is to be assigned to the field of controlled domestic ventilation Heat recovery. The ventilation units used there work mainly with cross-flow, cross-countercurrent and countercurrent heat exchangers. These heat exchangers consist of metal (e.g., Alu) or plastic (e.g., PVC). Your The task is to heat only the exhaust air to the supply air to transfer. The air types supply air and exhaust air should not mix. Appropriate Regulations in the building inspectorate approval provide values here.

Unterschiedliche Feuchtewerte gleichen sich nicht aus. Dies wirkt sich bei kalten Aussentemperaturen negativ aus. Sind die Feuchteeinträge in die Wohnung durch die Bewohner (u.a.) geringer als das Abführen von Feuchte durch den Luftaustausch im Rahmen der gewünschten Lufthygiene, wird es zu trocken. Die sich daraus ergebende Austrocknung der Wohnung mit allen ihren Nachteilen in Bezug auf Gesundheit und Sachschäden wie z.B. Risse bei Bauteilanschlüssen und Risse/Spalten in Parkett/Holzböden bergen relativ große Anwendungsprobleme. Diese sind wegen der relativ kurzen Zeit des Einsatzes von Wohnraumlüftungen noch nicht der Bedeutung gemäß thematisiert. Eine Nachfeuchtung mittels zentraler oder dezentraler Luftbefeuchtung ist eingeschränkt durchsetzbar und energetisch schwer vermittelbar.different Moisture values do not compensate each other. This affects cold Outside temperatures negative. Are the humidity entries in the apartment by the inhabitants (u.a.) Less than the removal of moisture through the Air exchange within the desired Air hygiene, it gets too dry. The resulting dehydration of the Apartment with all its disadvantages in terms of health and property damage e.g. Cracks in component connections and cracks / crevices in parquet / wood floors pose relatively large application problems. These are because of the relatively short time of using living space vents not yet themed in meaning. A re-humidification by means of central or decentralized air humidification is restricted enforceable and energetically difficult to communicate.

Eine System-Alternative bietet ein neu am Markt vorhandener Kreuzgegenstrom- bzw. Gegenstromwärmetauscher aus diffusionsoffenem Membranmaterial. Er überträgt bis zu 70% der Feuchte aus der Abluft auf die Zuluft. Dies erfolgt in Gas-Dampf-Form. Eine Kondensation auf der Abluftseite tritt nicht ein, auch nicht bei Außenlufttemperaturen unter 0°C, jedoch mit Limit nach unten. Der Einsatz dieses Wärmetauschers eröffnet somit die Möglichkeit, bei ausgeglichener und einer den anwesenden Personen gemäßen Luftmenge auf zusätzliche Befeuchtung im Bereich der Wohn-Schlafräume zu verzichten.A System Alternative offers a newly available cross countercurrent or countercurrent heat exchanger from diffusion-open membrane material. It transfers up to 70% of the moisture from the Exhaust air to the supply air. This is done in gas-vapor form. A condensation on the exhaust side does not occur, even at outside air temperatures below 0 ° C, but with limit down. The use of this heat exchanger open thus the possibility with balanced and a person of the appropriate amount of air on additional humidification in the area of living-sleeping rooms to renounce.

Ein auf den Markt kommendes Lüftungsgerät „Santos" (Hersteller: Paul Wärmerückgewinnung GmbH, Vettermannstr. 1–5, 08132 Mülsen St. Jakob) wird mit einem rückfeuchtenden Wärmetauscher und einem diffusionsdichten Wärmetauscher ausgeliefert. Der Betreiber soll je nach Jahreszeit die Wärmetauscher manuell austauschen. Dies ist aufwändig, erfordert Sachverstand und Zuverlässigkeit. Das angestrebte Ziel, eine Korrektur der Luftfeuchtigkeit, wird vom Gros der Anwender nicht erreicht werden.One on the market coming air handling unit "Santos" (manufacturer: Paul Heat recovery GmbH, Vettermannstr. 1-5 08132 Mülsen St. Jacob) is having a rewet heat exchangers and a diffusion-tight heat exchanger delivered. The operator should, depending on the season, the heat exchangers replace manually. This is laborious, requires expertise and reliability. The desired goal, a correction of humidity, will can not be reached by the majority of users.

Die hier vorliegende Erfindung/Lüftungsgerät (1) ist mit 2 Wärmetauschern ausgestattet:
Ein Wärmetauscher mit feuchtigkeitsübertragenden Trennmaterialien= Membrane. In der Trennschicht von Zuluft und Abluft findet neben der Wärmeübertragung zusätzlich eine Feuchteübertragung statt. Die Membrane nimmt Feuchtigkeit in Dampf- oder Gasform auf und überträgt sie zur jeweils trockeneren Luftseite, im Regelfall zur Zuluft (2).The present invention / ventilation device ( 1 ) is equipped with 2 heat exchangers:
A heat exchanger with moisture-transferring separating materials = membrane. In the separating layer of supply air and exhaust air in addition to the heat transfer additionally takes place a moisture transfer. The membrane absorbs moisture in vapor or gaseous form and transfers it to the drier air side in each case, as a rule to the supply air ( 2 ).

Ein herkömmlicher Wärmetauscher aus nicht feuchtigkeitsübertragenden Trennmaterialien, aus Alu oder anderen Metallen gefertigt und aus Kunststoff wie PP, PE, PVC. Es findet in der Trennschicht von Zuluft und Abluft ein Wärmeübergang statt (3).A conventional heat exchanger made of non-moisture-transferring separating materials, made of aluminum or other metals and made of plastic such as PP, PE, PVC. There is a heat transfer in the separating layer of supply air and exhaust air ( 3 ).

Zwei Feuchtefühler bzw. Hygrostate (F1 und F 2) beeinflussen mittels der Regelung (11) die Stellklappen (M), um die 2 Wärmetauscher ihrer Aufgabe gemäß mit Zu- und Abluft zu versorgen. Ausgeglichene Luftmengen ergeben bzw. halten sich durch Einsatz von konstantvolumenstromgesteuerten EC-Ventilatoren.Two humidity sensors or hygrostats (F1 and F 2) influence by means of the control ( 11 ) the butterfly valves (M) to supply the 2 heat exchangers according to their task with supply and exhaust air. Balanced air volumes result or maintain themselves through the use of constant-flow-controlled EC fans.

Durch die feuchtegesteuerte Umschaltung wird erreicht, dass – ein gewisser Feuchteeintrag durch Bewohnung vorausgesetzt – ein zusätzliches Befeuchten der Wohnung, insbesondere der Zulufträume entfallen kann. Zu hohe schädliche Feuchtewerte (> 50%) und zu niedrige schädliche Feuchtewerte (< 30%) werden verhindert.By the humidity-controlled switching is achieved that - a certain Moisture entry by occupancy provided - an additional moistening of the apartment, in particular the Zulufträume can be omitted. Too high harmful Humidity values (> 50%) and too low harmful Humidity values (<30%) are prevented.

Das Gerät besitzt einen Abluft-/Fortluftventilator (4) und einen Aussenluft-/ Zuluftventilator (5), sowie einen Abluftstutzen (6), Zuluftstutzen (7), Aussenluftstutzen (8), Fortluftstutzen (9).The device has an exhaust air / exhaust air fan ( 4 ) and an outside air / supply air fan ( 5 ), and an exhaust pipe ( 6 ), Supply air connection ( 7 ), Outside air connection ( 8th ), Exhaust air outlet ( 9 ).

Ein Bypass (10) verhindert, dass im Sommer die angesaugte Aussenluft durch den Wärmetauscher strömt. Das Gerät ist steuerbar über eine automatische Regelung (11).A bypass ( 10 ) prevents the sucked outside air from flowing through the heat exchanger in summer. The device is controllable via an automatic control ( 11 ).

Im Zuluftkanal befindet sich ein Fühler für Messung des Feuchtegrades (F1). Ein weiterer Feuchtefühler (F2) befindet sich in den belüfteten Räumen.in the Supply air duct is a sensor for measurement the degree of humidity (F1). Another humidity sensor (F2) is located in the ventilated rooms.
