Description

Brauchwasservorwärmer Brauchwasservorwärmer
Der Gegenstand des Gebrauchsmusters ist ein Brauchwasservorwärmer, der mit Heizwasser aus den Gas- und Ölkesseln gespeist wird, die an Zusammenarbeit mit den in der Fernwärmeversorgung üblichen Niederparameter-kesseln angepasst sind.The subject of the utility model is a domestic water preheater that is fed with heating water from the gas and oil boilers, which are adapted for cooperation with the low-parameter boilers common in district heating supply.
Aus der polnischen Beschreibung des Gebrauchsmusters Nr. Ru 55 852 ist ein Brauchwasservoiwärmer bekannt, der mit Heizwasser aus den Systemen in den mit Gas oder Heizöl beheizten Kesselhäusern gespeist wird und mit einem aus einigen Plattenwärmetauscher bestehenden Plattenwarmetauschersatz ausgerüstet ist. Der Wärmetauschersatz ist durch Anschlüsse in den Warmwasserauslauf-kollektor eingebaut und ist mit einem Stabilisator verbunden, der wiederum durch einen Stutzen und eine Umlau umpe mit einer Leitung für äußere Zirkulation sowie durch einen Stutzen, einen Rückschlagventil und eine Pumpe für innern Umlauf mit dem Kaltwasserkollektor verbunden ist. Der aus einigen Platten-wärmetauscher bestehende Wärmetauschersatz ist an die Heizwasserspeiseletung angeschlossen.From the Polish description of utility model no. Ru 55 852 a domestic water heater is known which is fed with heating water from the systems in the boiler houses heated with gas or heating oil and is equipped with a plate heat exchanger set consisting of a few plate heat exchangers. The heat exchanger set is installed through connections in the hot water outlet collector and is connected to a stabilizer, which in turn is connected to the cold water collector by a connection piece and a Umlau umpe with a line for external circulation and a connection piece, a check valve and a pump for internal circulation is. The heat exchanger set consisting of a few plate heat exchangers is connected to the heating water supply.
Auf dem Boden des gleichzeitigen Stands der Technik entstand die Aufgabe, eine Konstruktion des Brauchwasservorwärmers mit einer Schutz-maßnahme gegen Entstehung von Stämmen der Legionärskrankenheitsbakterien zu schaffen sowie entsprechende Lösungen für Beseitigung der Temperaturaufschich-tung des Warmwassers und für Erhalten der Wassertemperatur im Stabilisators-behälter von +60°C auf der ganzen Behältershöhe einzuführen. Der ausarbeitete Vorwärmer soll darüber hinaus der Zusammenarbeit mit den Kondensationskesseln vom hochen technischen Wirkungsgrad angepasst werden.On the basis of the state of the art at the same time, the task arose to create a construction of the domestic water preheater with a protective measure against the development of strains of legionnaire's disease bacteria, as well as corresponding solutions for eliminating the temperature build-up of the hot water and for maintaining the water temperature in the stabilizer tank from + 60 ° C across the entire height of the container. The developed preheater is also to be adapted to the cooperation with the condensation boilers of high technical efficiency.
Der Brauchwasse-rvorwärmer, der dem Gebrauchsmuster gemäß einen Wärmetauschersatz enthält, der aus einigen in den Kaltwasserkollektor und in den Warmwasserausgangskollektor eingebauten sowie an die Heizwasserspeiseleitung angeschlossenen Plattenwärmetauschern zusammengesetzt ist, charakterisiert sich dadurch, dass er eine Mischeinheit besitzt, die ein thermostatisches Ventil, einen Ausgangskollektor, ein Kontrollthermometer für Überwachung des warmen Brauchwassers mit der Temperatur von +60°C und ein Thermometer für Zirkulation des warmen Brauchwassers mit der Temperatur von +55°C enthält. Die Mischeinheit ist durch einen Auslaufstutzen und eine Leitung mit Wasser mit erhöhter Temperatur mit dem Stabilisator verbunden. Der Stabilisator ist durch den Plattenwarmetauschersatz mit einem Sicherheitsventil und mit einem Ausdehungs-gefaß von der Kaltwasserseite hydrauHsch verbunden.The domestic water preheater, which, according to the utility model, contains a heat exchanger set consisting of some plate heat exchangers installed in the cold water collector and the hot water outlet collector and connected to the heating water supply line, is characterized by the fact that it has a mixing unit that has a thermostatic valve, an outlet collector , contains a control thermometer for monitoring hot domestic water at a temperature of + 60 ° C and a thermometer for circulating hot domestic water at a temperature of + 55 ° C. The mixing unit is connected to the stabilizer by an outlet nozzle and a line with water at an elevated temperature. The stabilizer is hydraulically connected by the plate heat exchanger set with a safety valve and with an expansion vessel from the cold water side.
Der diesem Gebrauchsmuster gemäß ausgeführte Vorwärmer enthält einige Konstruktionslösungen sowie technologische Lösungen, die vor Entstehung der Bakterienflora, und besonders vor Entstehung von Stämme der Legionärs-krankenheitbakterien schützen, deren intensive Entwicklung in Temperaturen von 20°C bis 55°C erfolgt.The preheater designed according to this utility model contains some construction solutions as well as technological solutions that protect against the formation of the bacterial flora, and especially against the formation of strains of Legionnaire's disease bacteria, whose intensive development takes place in temperatures from 20 ° C to 55 ° C.
Die eingesetzte Mischeinheit mit einem thermostatischen Mischventil ermöglicht Erhaltung im Stabilisator der erhöhten Temperatur von +70°C sowie nach Vermischen erlaubt Zuführung in die Abnahmeanlage des Wassers mit der erforderlichen Temperatur von +60°C. Weil bei Anlagenausführung aussließlich nichtrostender Stahl eingesetzt wird, ist die Ablagerung von Kesselstein und Sedimenten mit Legionärskrankenheitbakterien begrenzt sowie ist periodische Erhöhung der Warmwassertemperatur bis zum +80---90°C und damit vollständiege Liquidation der Legionärskrankenheitbakterien in der Vormärmersanlage möglich.The mixing unit used with a thermostatic mixing valve enables maintenance in the stabilizer of the elevated temperature of + 70 ° C and, after mixing, allows feeding into the water intake system at the required temperature of + 60 ° C. Because only stainless steel is used in the system design, the deposit of scale and sediments is also included Legionnaire's disease bacteria are limited and periodic increases in the hot water temperature up to +80 --- 90 ° C and thus complete liquidation of the Legionnaire's disease bacteria in the preheater system are possible.
Der Vorwärmer ist auch völlig der Zusammenarbeit mit den Kondensationskesseln vom hochen technischen Wirkungsgrad angepasst. Das garantiert sehr günstige Abkühlung des Heizwassers um ca. +35°C, weil die Voraussetzung für Konden-sationsentstehung in den Kondensationskesseln des Gas- und Ölkesselhauses die ständige Erhaltung der Rücklauftemperatur unterhalb von +57°C ist. Erzielung solcher Temperaturen in den bisher angewandten, mit Rohrheizschlangen aus-gerüsteten Kapazitäts- und Durchlaufvorwärmern ist erschwert und gewährleistet die völlige Kondensationsbedingungen nicht.The preheater is also fully adapted to cooperation with the condensing boilers with high technical efficiency. This guarantees very cheap cooling of the heating water by approx. + 35 ° C, because the prerequisite for the formation of condensation in the condensation boilers of the gas and oil boiler house is the constant maintenance of the return temperature below + 57 ° C. Reaching such temperatures in the previously used capacitance and continuous preheaters equipped with tubular heating coils is difficult and does not guarantee the complete condensation conditions.
