Abstract

The carrier liquid, e.g. a watery alcohol soln. (W) is circulated by a pump (P). The refrigeration results whilst the refrigerant absorbed in the liquid, then with heat take-up and pressure increase before the throttle valve (D) condenses in the condenser (F). With heat reception the liquid is vaporised in section (K). A refrigerant is used which simultaneously serves as a means of protecting against frost for the carrying liquid (W). The heat transferred from the heat exchanger to the carrier liquid is transported by means of connections (V) with insulated containers (B), which can be decoupled, and across a mechanical system. ADVANTAGE - Produces overall balance for engines and gives improved fuel utilisation. Small environmental nuisance due to noise, heat and exhaust gases. System has many uses, e.g. air conditioning for driver cabins and engine intercooler.

Description

Die Erfindung betrifft eine Kältemaschine nach dem bekannten Absorberprinzip. Die Kälte wird durch Umwandlung der "Abfallenergie" eines Verbrennungsmotors erzeugt und die verbleibende Restwärme wird verteilt oder verzögert an die Umgebung abgegegeben. Das spart insgesamt Energie.The invention relates to a refrigerator according to the known Absorber principle. The cold is transformed by the "Waste energy" generated by an internal combustion engine and the remaining heat is distributed or delayed to the Given environment. This saves energy overall.

Wegen des geringen Wirkungsgrades werden Absorberkälteanlagen selten verwandt. Aus dem gleichen Grund werden in Verbindung mit Verbrennungsmotoren fast nur Kälteanlagen nach dem Kompressorprinzip angewandt. Ansonsten erfolgt nach Erreichen der Betriebstemperatur die Kühlung durch das rasche Abführen von Hitze an die Umgebung.Because of the low efficiency, absorber refrigeration systems rarely related. For the same reason, in conjunction with Internal combustion engines almost only refrigeration systems after the Compressor principle applied. Otherwise takes place after reaching the Operating temperature cooling by rapidly dissipating heat to the environment.

Die der Erfindung zugrundeliegende Aufgabe wird darin gesehen, in der Gesamtbilanz für Motoren eine bessere Treibstoffausnutzung, geringere Umweltbelastungen durch Lärm, Hitze und Abgase im Betrieb, mit einer einfachen Kältemaschine zu verbinden, die vielfach genutzt werden kann: etwa als Klimaanlage für die Fahrerkabine oder als Motor-Intercooler.The object underlying the invention is seen in the overall balance for engines better fuel utilization, lower environmental pollution due to noise, heat and exhaust fumes Operation to connect with a simple chiller that can be used in many ways: for example as air conditioning for the Driver's cabin or as an engine intercooler.

Die gestellte Aufgabe wurde durch die Lehre nach Anspruch 1 gelöst und durch die folgenden Ansprüche in der Anwendung ausgeweitet.The task was solved by the teaching of claim 1 and extended in application by the following claims.

Die Figur zeigt die Lösung der Aufgaben im Schema.The figure shows the solution of the tasks in the scheme.

Der zum Lärmschutz im Rahmen C abgekapselte, auf der Lafette L fahrbare Motor M erhitzt durch einen im Abgaskanal untergebrachten Gegenstromwärmetauscher A eine wäßrige Alkohol-Lösung W, die von einer Pumpe P in Zwangsumlauf gehalten wird. Durch zunehmende Wärmezufuhr verdampft im Wärmetauscher A zunächst ein Teil des im Wasser gelösten Alkohols. Da sich der durch die Verdampfung entstehende Druck jedoch durch das Drosselventil D nicht sofort entspannen kann, verflüssigt sich der Alkohol im Bereich F wieder. Durch die Vergasung des Alkohols im Bereich K wird der Umgebung Wärme entzogen. Danach wird der Alkohol dem umlaufendem Wasser im Absorber S wieder in gasförmigem Zustand zugeführt, unter fortlaufendem Umlauf über V- E- R- V- abgekühlt und weitgehend verflüssigt. Der ständige Kreislauf beginnt sodann bei A wieder.The encapsulated for noise protection in frame C, on the carriage L Mobile engine M heated by one housed in the exhaust duct Counterflow heat exchanger A an aqueous alcohol solution W, which by a pump P is kept in forced circulation. By increasing Heat supply evaporates in the heat exchanger A first part of the im Alcohol dissolved in water. Because of the evaporation However, pressure created by the throttle valve D does not immediately can relax, the alcohol liquefies again in area F. By gasifying the alcohol in area K, the environment Deprived of heat. Then the alcohol is in the circulating water Absorber S fed back in the gaseous state, under continuous circulation via V- E- R- V- cooled and largely liquefied. The constant cycle then starts again at A.

Selbstverständlich sind außer dem gezeigtem transportablen, durch den gelösten Alkohol frostgeschützten Kühlwasserbehälter B auch andere Lösungen möglich. So ist auch ein durch Umleitung entsprechender Gegenstromwärmetauscher von Heizung auf Kühlung oder umgekehrt umschaltbares Wärmeum- oder Ableitesystem durch die Ansprüche abgedeckt.Of course, in addition to the shown, are transportable the dissolved alcohol frost-proof cooling water tank B also other solutions possible. So is one by redirection Corresponding counterflow heat exchanger from heating to cooling or vice versa switchable heat diversion or dissipation system by the Claims covered.

Die zuletzt erwähnte Anwendung kann zur wirtschaftlichen Klimatisierung von Fahrzeugkabinen verwendet werden.The latter application can be used for economic Air conditioning of vehicle cabins can be used.
