Room ventilating and air conditioning system having at least one flow duct for a medium flowing therein and having at least two air-related components

Abstract

A room ventilating and air conditioning system has at least one flow duct for a medium flowing therein and at least two air-related components. One component has a receiver and one component has a transmitter and the two components are connected via a wire-free connection, in particular a radio connection. At least one of the transmitters should project, at least with a subregion, to such an extent into the interior of the flow duct that the waves emitted by this transmitter are conducted substantially through the flow duct and / or at least one of the receivers should project, at least with a subregion, to such an extent into the interior of the flow duct that it is able to receive the waves conducted substantially through the flow duct.

AI Technical Summary

Benefits of technology

[0009]The system can be employed without structural changes in stock systems, so that stock systems can therefore be re-equipped without difficulty. The system can have any desired number of components. In its simplest configuration, only two components are provided, which are connected to each other in a wire-free manner.

[0011]If there is a building services control system, it is of course possible for a conventional central device belonging to the building services control system of a room ventilation system likewise to be equipped with at least one transmitter and / or at least one receiver. In this way, for example, the rotational speed of a component constructed as a fan can be adapted, with the result of a saving in energy, by means of de-restricting the distribution system or the feed air temperature by decoupling temperature regulation and volume flow.

[0017]Given such a configuration, the transmitter and the receiver of a component are connected functionally to each other, so that to this extent reception and transmission are possible. Such a configuration is recommended in particular when, for example, a number of components arranged one after another are arranged in a flow duct and communicate with one another. This permits a particularly energy-optimized operation of the system, since the air-conditioning action of the complete system can be adapted optimally at any point in the system.

[0021]Components with repeaters are recommended in particular in complex systems in which, for example, a plurality of secondary flow ducts extending parallel to one another and having components located therein in each case, such as volume flow regulators and fans, are supplied by a main flow duct. If, for example in the case of a variable volume flow at the outlet of a secondary flow duct, too low a quantity of air flowing out is measured by a measuring device, an appropriate signal to change the valve position is transmitted from the corresponding measuring device, via the transmitter, to the component assigned to this secondary flow duct and, for example, formed as a volume flow regulator, instead of an increase in the output of the fan arranged in the main flow duct. This permits energy-optimised operation.

[0024]In the system according to the invention, the control and / or regulating device(s) are decentralised, since each component can preferably itself be assigned a corresponding device. Preferably, the corresponding control and / or regulating devices are protectively encoded, self-detecting, self-addressing and self-configuring. This simplifies the mounting and commissioning on site, since the components within the system identify themselves.

Problems solved by technology

It proves to be disadvantageous that such radio connections have only a very limited range and therefore corresponding systems can be used only to a restricted extent, in particular in multi-storey buildings.

For example, room walls or other objects lead to considerable impairment of the radio connection.

An arrangement of two components connected to each other via a radio connection in different rooms or even on different floors is therefore virtually impossible.
