Description

The invention relates to a fire water container according to the preamble of claim 1.

Such fire water containers are used to provide extinguishing water.

From the DE 16 33 160 U For example, is known by means of a heating Löschwassertank known in which by means of an electric heater, the extinguishing water to be protected from freezing.

The disadvantage, however, is that because of the possibility of extreme and sometimes longer lasting minus degrees, the electric heater must be designed with a large electrical power. But that makes this electric heating in their purchase expensive. In addition, the electricity costs are high because of the large electrical power.

The invention is therefore based on the object to develop a fire water container with a cryoprotectant of water in a fire tank, which can be operated with a standard electrical mains voltage and is inexpensive.

This object is solved by the characterizing features of claim 1. Expedient refinements emerge on the device side from the subclaims 2 to 9.

The new fire water container eliminates the disadvantages of the prior art.

An advantage of using the new fire extinguisher is that a fire extinguishing freeze protection material is in thermal contact with the water stored in the extinguishing water tank, because this ensures the functionality of the extinguishing water freeze protection material.

It is also advantageous if in the extinguishing water tank an electrically operated heating cartridge and a temperature sensor arranged such that when falling below a measured temperature with the temperature of the water in the fire tank under a minimum temperature heats the heating cartridge and thus gives off heat to the water in the fire tank. As a result, an extinguishing water freeze protection is realized, which uses as a base load the heat released by the heating cartridge and only in exceptional cases, e.g. unusually long-lasting negative temperatures, which emits during the crystallization of the fire extinguishing agent freeze protection material to the water of the extinguishing water tank.

It is advantageous if the immersion heater has on its outer wall an opening providing and consisting of the Löschwassereinfrierschutzmaterial sheath, because it also ensures protection for failure of the heating element insofar that stopped by the Löschwassereinfrierschutzmaterial freezing of the water in Löschwassertank initially and so that it is postponed in time.

• - die Phasenwechseltemperatur des Löschwassereinfrierschutzmaterials im Bereich zwischen 1 °C und 5 °C liegt und
• - das Löschwassereinfrierschutzmaterial beim Erwärmen des Wassers im Löschwassertank auf die Phasenwechseltemperatur des Löschwassereinfrierschutzmaterials sich wieder verflüssigt.

It is also advantageous that the extinguishing water freeze protection material consisting of a PCM material when cooling the water in Löschwassertank to a phase change temperature of Löschwassereinfrierschutzmaterials its enthalpy of enthalpy to the water in Löschwassertank and thus keeps the temperature of this water constant, wherein

• - The phase change temperature of Löschwassereinfrierschutzmaterials in the range between 1 ° C and 5 ° C and
• - The Löschwassereinfrierschutzmaterial when heating the water in Löschwassertank to the phase change temperature of Löschwassereinfrierschutzmaterials liquefied again.

Thus, the latent heat of Löschwassereinfrierschutzmaterials is used when freezing the water in Löschwassertank as a heat source to prevent the freezing of the water.

The new fire water containers are to be explained in more detail in five embodiments.

In the walk-in room 4 who is on the container 1 arranged container doors 5 can be opened, open a fire water extraction 6 the extinguishing water tank 2 and a fire water supply 7 of extinguishing water tank 2 , In addition, the fire water tank points 2 a walk-in room 4 directed manhole 8th on which by an insulated, removable cover 9 is closed.

Here are the fire water extraction 6 and the fire water supply 7 each by shut-off valve 10 closable.

In addition, the fire water tank points 2 one from the fire tank 2 outside the container 1 open-ended venting 11 on.

Between the fire water tank 2 , the dividing wall 3 and three inner walls of the container 1 is a thermal insulation granules 12 ,

In the first embodiment of the fire water container, according to the 1 , is in the fire tank 2 an electrically operated heating cartridge 13 and a temperature sensor 14 arranged such that when falling below a with the temperature sensor 14 measured temperature of the water in the fire tank 2 below a minimum temperature the heating cartridge 13 heats and thus heat to the water in the fire tank 2 emits.

The mode of action of the new fire water container is now to the second embodiment according to the 2 be explained.

It is assumed that the fire water tank 2 filled with water and the outside temperature is a long time well below 0 ° C.

As a result, the water will cool down over time until the risk of freezing exists. Now reach the water temperature and thus the temperature of the layer 15 the phase change temperature of the extinguishing water freeze protection material 16, so this gives its enthalpy of enthalpy to the water in Löschwassertank 2 thus keeping the temperature of this water constant.

At outside temperatures of well over 0 ° C, the water in the fire tank is heated 2 again. Now reach the water temperature and thus the temperature of the layer 15 the phase change temperature of the extinguishing water freeze protection material 16 , so the extinguishing water freezing protection material 16 the water in the fire tank 2 Heat until completely liquefied again.

Is in the fire tank 2 the heating cartridge 13 arranged, so is by heat emitted by the heating cartridge 13 the water in the fire tank 2 reheated until the phase change temperature of the extinguishing water freeze protection material 16 is reached, then withdraws the extinguishing water freezing protection material 16 the water in the fire tank 2 Heat until it is completely liquefied again, this amount of heat is compensated by the heating cartridge.

Must after a fire service use the fire water tank 2 be filled again and the outside temperatures are well below 0 ° C, then there is a risk that the water after flowing into the Water tank 2 freezes through his relaxation. Then also cooled by the water contacted wall areas of the fire water tank 2 and thus also in this area the layer 15 until the phase change temperature of the extinguishing water freeze protection material 16 is reached.

When this phase change temperature is reached, this gives its enthalpy of solidification to the water in the extinguishing water tank 2 and liquefies this again.

It is conceivable, the power supply of the heating element 13 to realize by an electrical connection to a street lamp.

Also, it is conceivable the outer wall of the container 1 darker in color, so that more sunlight is absorbed and thus the container 1 is heated from the outside, whereby with a resulting amount of heat in particular the extinguishing water tank 2 including extinguishing water freeze protection material 16 is heated.
