EP2256420B1 - Method for ventilating a flat heater and flat heater - Google Patents

Abstract

The method involves opening out the fluid channels in separated openings in a functional connection. The openings are sealed with detachable venting plugs. The fluid channels open into the surrounding area of the plate radiator (1) by releasing the venting plugs, and the heating plates are aerated. The openings are opened directly into the surrounding area by releasing the venting plugs. An independent claim is also included for a plate radiator with a sealing surface.

Description

The invention relates firstly to a method for venting a panel radiator with a connecting element between a front heating plate of the Plattenheizkörpers and at least one further heating plate of the Plattenheizkörpers, each having a fluid channel from the heating plates, wherein the fluid channels open in separate openings in a functional connection, and with a releasable vent stopper that closes the orifices, wherein the fluid channels are opened to an environment of the plate heater by venting the vent stopper and the heating plates are vented. Furthermore, the invention relates to a set up for carrying out such a method panel radiator.

Method and plate heater of the aforementioned type are generally known under the name "serial radiator". Illustratively disclosed DE 196 14 330 C1 Such a plate heater, where the vent stopper for venting opens an orifice of the first fluid channel into the second fluid channel and an orifice of the second fluid channel to the surroundings of the plate heater.

When filling for the first time in the heating plates of a serial radiator, the level of the heating medium rises at different speeds and the air is expelled at different speeds into the environment. This is e.g. Also dependent on how far the control valve is open and whether the circulating pump for the heating medium during the filling and bleeding process is running. When filling serial radiators of the aforementioned type with a common purpose venting open to the environment function port for all heating plates regularly flows from the faster filled heating plate heating means from the functional connection, while the other heating plate still contains air.

When venting the known panel radiator regularly flows in the function connection heating means from the faster filled in the other heating plate and disturbs or prevents their complete venting.

The vent plug of a serial plate radiator is also usually not completely removed from the functional connection for venting, but only solved by turning the thread. On the known panel heater is the mouth of the first fluid channel in the second by a sliding radial seal, the mouth of the second Fluid channel sealed into the environment by a conical seat seal. When loosening the vent plug so the conical seat seal is opened immediately, the radial seal but only at the complete exit from the mouth.

If the vent stopper on the known panel radiator is not turned far enough out of the functional connection, then the radial seal-unnoticed by the user-remains in the opening and in turn disturbs or prevents the venting of the connected heating plate.

task

The invention has for its object to ensure a safe venting.

solution

Starting from the known method is proposed according to the invention that by opening the vent stop the mouths are opened directly to the environment. By not combining both fluid channels, but instead opening them directly to the environment, the method according to the invention effectively avoids an overflow of heating medium from one into the other fluid channel. "Conflicts" between water (heating) and air and mutual disability are thus avoided.

In the context of a method according to the invention, the openings are preferably opened simultaneously by releasing the vent stopper. Such an inventive method effectively avoids unnoticed non-opening of one of the orifices.

Starting from the known plate radiators, the invention proposes that the vent stopper closes the mouths and the mouths can be opened directly to the environment by releasing the vent stopper. A panel heater according to the invention makes it possible to carry out one of the above-described methods according to the invention and is distinguished by the advantages mentioned there.

Preferably, the fluid channels in the mouths in a mouth opening into the environment lead to a panel heater according to the invention. In such a panel heater according to the invention, the two mouths can be particularly easily closed by a common vent plug.

Particularly preferably, the mouth level in the assembled state of the panel radiator runs vertically on such a panel radiator according to the invention. If heating medium flows from an orifice in a vertically extending orifice plane over another orifice, it does not build up any dynamic pressure on it, which disturbs or even prevents the further outflow of air there.

Advantageously, the fluid channels continue to flow parallel to the environment in a panel heater according to the invention. The functional connection of such a panel heater according to the invention is particularly easy to manufacture. The sealing body of the vent valve may have a simple cylindrical shape.
