Abstract

Heat is stored as the latent heat of fusion by melting a working substance, which must have a m.pt. within the working temp. range. Paraffin wax (m.pt. 54 deg.C) is suitable. The heat reservoir is a thermally insulated vessel contg. the working substance, having coils for the supply and removal of heat. The working substance must also have high heat of fusion, be stable to ageing and be cheap. The heat storage capacity is large within a relatively narrow working temp. range: this must improve conditions for using the heat evolved. Paraffin wax has latent heat of fusion of about 146 kJ/kg, so that 1 cu.m. can store about 146,000 kJ for withdrawal at about 50 deg.C. This is about as much as the useful heat available in 5 l fuel oil.

Description

Zweckpurpose

Die Erfindung beinhaltet einen Wärmespeicher, bei dem die Schmelzwarme als Energiespeichermöglichkeit nutzt wird.The invention includes a heat store in which the heat of fusion is used as an energy storage option.

Neu gegen bisher bekannte Erfindungen: Bisher werden als Wärmespeichermedien vorwiegend Wasser und feste Stoffe wie Schamotte benutzt. Hierbei wird als Energiespeicherform der Energieinhalt auf grund der Medientemperatur ausgenutzt, d. h.New against previously known inventions: So far, as heat storage media mainly water and solid materials such as fireclay are used. This is used as an energy storage form the energy content is used due to the temperature of the medium, d. H.

mit zunehmender Wärmeabgabe sinkt die Abgabetemperatur.with increasing heat dissipation, the output temperature decreases.

Neu ist die Verwendung einer Substanz die bei Wärmezuführung über ihrer Schmelztemperatur erhitzt und erschmolzen wird. Bei TSärmeabgabe kann eine relativ große Wärmemenge bei konstanter Temperatur abgegeben werden. Dies ergibt im nutzbaren Temperaturbereich eine höhere Speicherkapazität und bessere Voraussetzungen bei der Anwendung der abgegebenen Wärme.What is new is the use of a substance that is exposed to heat their melting temperature is heated and melted. In the case of heat dissipation, a Relatively large amounts of heat are given off at a constant temperature. This gives A higher storage capacity and better conditions in the usable temperature range when applying the heat given off.

Beschreibung Der Wärmespeicher besteht im wesentlichen aus einet allseitig gut isolierten behälter mit eingebauten Rohrschlangen für Wärme zu- u.Description The heat storage consists essentially of one on all sides well-insulated container with built-in pipe coils for heat supply u.

-abführung. In dem Behälter wird für die Wärmespeicherung eine Substanz eingefüllt, die folgende Anforderungen erfüllen muß: a) Schmelztemperatur in ähnlicher Größenordnung wie die Nutztemperatur, b) möglichst hohe Schmelzwärme, c) gute Alterungsbeständigkeit, schwer brennbar, preisgünstig.discharge. A substance is used for heat storage in the container filled, which must meet the following requirements: a) Melting temperature similar The same order of magnitude as the useful temperature, b) the highest possible heat of fusion, c) good aging resistance, flame-retardant, inexpensive.

Funktion In Zeiten von Wärmeüberschuß wird dem Speicher über die Rohrschlange Wärmeenergie zugeführt mit Temperaturen höher der Schmelztemperatur. Durch genügend hohe wärmezufuhr wird die Substanz vollständib erschmolz n. Damit steht im Wärmespeicher eine relativ große Wärmemenge bereit, die bei konstanter Temperatur, der Gefriertemperatur, abgegeben werden kann. Nimmt man z. B. Paraffin mit einer Schmelztemperatur von 54° C (327 K) und einer Schmelzwarme von ca. 146 kJ / kg so kann aus einem Speicher mit 1m3 Speichersubstanz 146 000 kJ bei einer Nutztemperatur von ca. 50° C (323 K) abgegeben werden; entspricht etwa dem nutzbaren Wärmewert von 5 1 Heizöl.Function In times of excess heat, the storage tank is via the pipe coil Heat energy supplied at temperatures higher than the melting temperature. By enough high heat supply the substance is completely melted n. This is in the heat storage a relatively large amount of heat that is available at a constant temperature, the freezing temperature, can be delivered. If you take z. B. paraffin with a melting temperature of 54 ° C (327 K) and a heat of fusion of approx. 146 kJ / kg so can from a storage with 1m3 storage substance 146,000 kJ at a useful temperature of approx. 50 ° C (323 K) are submitted; corresponds roughly to the usable heat value of 5 liters of heating oil.
