Description
Wärmepumpenanlage, deren Wärmepumpe nach Art der Kompressions
KÏltemaschine arbeitet.
Die Erfindung betrifft eine Wärmepumpenanlage, de-ren Wärmepumpe nach Art der Kompressions-Ea. ltemasch. ine arbeitet.
Bekanntlich geht das Bestreben dahin, das aufzuheizende Mittel, vorzugsweise Was- ser, im Verflüssiger auf die Verflüssigungstemperatur des Wärmeträgers der WÏrmepumpe zu bringen, da dies f r die Wirt schaftlichkeit von Anlagen der erwähnten Art günstig ist. Das erfordert jedoch gro¯e Wärmeaustauschflächen im Verflüssiger, so da, sich dessen Anschaffungspreis hoch stellt, was wieder auf die Wirtschaftlichkeit der Anlage driickt.
Die hier gestellte Aufgabe wird nun ge mäB vorliegender Erfindung unter Vermeidung der angeführten MÏngel dadurch gel¯st, daB dem Verflüssiger der Wärmepumpe, in der Strömungsrichtung des Wärmeträgers der Wärmepumpe betrachet, ein Hilfswärmeaus- tauscher vorgeschaltet ist, in welchem dieser Wärmeträger seine Uberhitzungswärme an das im Verflüssiger bereits vorgewärmte, auf zuheizende Mittel abgibt.
Auf der beiliegenden Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegen- standes schematiseh veranschaulicht, und zwar zeigt die Abbildung eine Wärmepumpen- anlage, die zum Aufheizen von Wasser dient.
Die nach Art der Kompressions-KÏltemachine arbeitende Wärmepumpe weist einen Verdichter 1 f r den in einem ge- schlossenen Ereislauf zu fordernden Wärme- träger dieser Pumpe, ferner einen Verflüssi- ger 2 und einen Verdampfer 3 auf. Dem Verflüssiger 2 ist, in der Stromungsrichtung des Wärmeträgers der Wärmepumpe betrachtet, ein Hilfswärmeaustauscher 4 vorgeschaltet.
In letzterem gibt dieser Wärmeträger seine Überhitzungswärme im Gegenstrom an aufzuheizendes Wasser ab, welches im Verflüs- siger 2 bereits vorgewärmt worden ist.. Das im Verflüssiger 2 und im Hilfswärmeaus- tauscher 4 aufgeheizte Wasser gelangt dann in eine Wärme nach aussen abgebende Vorrichtung 5, die zum Beispiel eine Anzahl Radiatoren aufweisen kann, und strömt hierauf in den Verflüssiger 2 zurück, um dort aufs neue aufgeheizt zu werden.
Um sich ein Bild über die Arbeitsweise der beschriebenen Warmepumpenanlage machen zu können, sei erwähnt, da¯ das dem Verflüssiger 2 zuströmende, aufzuheizende Wasser in der Vorrichtung 5 auf 50 C abgekühlt und dann im Verflüssiger 2, bei einer Verflüssigungstemperatur des Wärmeträgers der Wärmepumpe von 68¯, auf etwa 66 und im Hilfswärmeaustauscher 4 weiter auf etwa 70 aufgeheizt werden kann.
Die besten Ergebnisse lassen sich erzielen, wenn der Hilfswärmeaustauscher, wie er wähnt, als Gegenstromwärmeaustauscher ausgebildet ist. Im Bestreben, die Anlage m¯giichst zu verbilligen, empfiehlt es sich, Verflüssiger und Wärmeaustauscher zu einem Stück zusammenzubauen, sie also in demselben Gehäuse unterzubringen.
Heat pump system whose heat pump is based on the type of compression
The refrigeration machine is working.
The invention relates to a heat pump system, whose heat pump of the compression type Ea. ltemasch. ine works.
As is known, efforts are made to bring the medium to be heated, preferably water, in the condenser to the condensation temperature of the heat transfer medium of the heat pump, since this is beneficial for the economy of systems of the type mentioned. However, this requires large heat exchange surfaces in the condenser, so that its purchase price is high, which again reduces the efficiency of the system.
The problem set here is now achieved according to the present invention, avoiding the deficiencies mentioned, in that the condenser of the heat pump, viewed in the flow direction of the heat carrier of the heat pump, is preceded by an auxiliary heat exchanger, in which this heat carrier transfers its superheat to the releases pre-warmed agents to be heated in the condenser.
An exemplary embodiment of the subject matter of the invention is schematically illustrated in the accompanying drawing, specifically the figure shows a heat pump system which is used to heat water.
The heat pump, which operates in the manner of the compression refrigeration machine, has a compressor 1 for the heat carrier of this pump to be conveyed in a closed circuit, and also a condenser 2 and an evaporator 3. An auxiliary heat exchanger 4 is connected upstream of the condenser 2, viewed in the direction of flow of the heat carrier of the heat pump.
In the latter, this heat transfer medium releases its superheating heat in countercurrent to the water to be heated, which has already been preheated in the condenser 2. The water heated in the condenser 2 and in the auxiliary heat exchanger 4 then passes into a device 5 which emits heat to the outside for example, can have a number of radiators, and then flows back into the condenser 2 in order to be heated again there.
In order to get an idea of how the described heat pump system works, it should be mentioned that the water to be heated flowing into the condenser 2 is cooled to 50 C in the device 5 and then in the condenser 2 at a condensation temperature of the heat transfer medium of the heat pump of 68 ¯, to about 66 and in the auxiliary heat exchanger 4 can be further heated to about 70.
The best results can be achieved if the auxiliary heat exchanger, as it mentions, is designed as a counterflow heat exchanger. In an effort to make the system as cheap as possible, it is advisable to assemble the condenser and heat exchanger into one piece, i.e. to place them in the same housing.
