Description

The present invention relates to a tempering system, suitable for controlling the ambient air of terraces.

Such tempering, also known as patio heaters, have become increasingly popular in recent years and are used in particular in the gastronomy and there for the heating of beer gardens and marquees or directly outdoors. As a heat source is usually a gas burner, the delivery of heated air via a kind of mushroom head. As an alternative to the gas-powered patio heater also electrically powered patio heaters are known. From the point of view of environmental policy, however, both systems are rejected almost equally strongly, since their heating efficiency is low and such devices, especially if they are operated by gas, are also emission-intensive.

Regardless of the environmental considerations, it remains undisputed that there is a great need for such patio heaters and so it is an object of the invention to provide the public with a tempering, suitable for controlling the ambient air of terraces, the more sustainable from the point of view of environmental policy operate and at the same time still easy to use and inexpensive in operation.

FIG. 1 illustrates a possible embodiment of the temperature control system proposed here, suitable for controlling the ambient air of terraces.

In the illustrated system, the one secondary block system comprises a double-walled storage vessel (2-5) having a capacity of about 150 liters for receiving water as a second medium inside its inner shell. In the interior of the inner shell of this storage vessel (2-5) protrude the means (3) for guiding the first medium, which here is glycol-containing water, as a spiral laid pipe inside. The means (3) for guiding the first medium are connected via the return passage (4) in the inner passage of the double-walled vertical pipe (10) to an air heat pump (1), which is structurally separate from the secondary block system, spaced from this secondary block system , is set up. The air heat pump (1) heats the first medium, the heated medium is supplied via the leading passage connection (4) to the means (3) for guiding the first medium within the storage vessel (2-5) where it transfers its heat to the water in the storage vessel (2-5). The then cooled first medium is then fed back to the air heat pump via the returning passage connection (4).

The outer shell of the storage vessel (2-5) is formed as means (6) for guiding ambient air, which is heated when the water is heated inside the inner shell of the storage vessel (2-5). At the lower end of the outer shell of the storage vessel (2-5) are suction openings (7) for the ambient air, identified in the figure as Au-βenluft to recognize. The sucked air is sucked up between the inner and outer sheath of the storage vessel (2-5) by means of the fan (9), wherein the sucked air heats up to the wall of the inner shell of the storage vessel (2-5). The thus sucked, heated air is then forced through the fan (9) in the outer passage of the double-walled vertical tube (10) and fed from there to the numerous blow-out (8), which serves as a blow-off ring at the outer end of a mushroom shield, the upper end of the double-walled vertical tube (10) is placed, are formed.

Such a system guarantees an effective heating of beer gardens and marquees, which is sustainable to operate in terms of environmental policy, the system is easy to use and inexpensive in operation at the same time.

If the secondary block system according to FIG. 1 Connected to an air heat pump operated in cooling mode, the illustrated system is also capable of providing pleasant cooling on terraces and in beer gardens and marquees on hot days.

Both in the heating and in the cooling mode, the suction openings (7) and the blow-out openings (8) can be interchanged with one another via a switched-over fan (9).
