Description

System and method for ventilating and/or venting at least one living and/or working space

Technical Field

The present invention relates to a system and method for ventilating and/or venting at least one residential and/or work space.

Background

Systems for ventilating and/or venting at least one residential and/or work space are known. The system may have one or more intake channels for supplying air into the living and/or working space, one or more exhaust channels for exhausting air from the living and/or working space, one or more fans for delivering air, a conditioning unit for operating the fans, and one or more sensors connected to the conditioning unit.

Disclosure of Invention

The invention proceeds from a system for ventilating and/or venting at least one living and/or working space, having one or more inlet channels, one or more outlet channels, one or more fans, a control unit for actuating the fans, and one or more sensors connected to the control unit.

A system for ventilating and/or venting at least one residential and/or working space is proposed, wherein at least one sensor is arranged in the vicinity of a location affecting the air quality in the at least one residential and/or working space.

A system for ventilating and/or evacuating at least one living and/or working space is understood here to mean a device for ensuring a certain air quality in a substantially closed space for people, animals and/or plants. This may be a central or non-central, regulated or controlled, ventilation facility with or without heat recovery. Fresh air, for example external air or an external air-circulating air mixture, can flow into the space via the intake channel. Used air, for example odorous, humid or particle-laden air, in particular air of poor quality, can flow out of the space through the exhaust channel. The fan may cause air movement and flow through the channels and spaces. The fan is a switchable and/or adjustable fan, i.e. the fan can be operated in on/off operation and/or in speed-adjusted operation. Of volumetric flow of air delivered by fansThe size, in particular the magnitude, varies with the rotational speed of the fan. The air volume flow in the channel system formed by the inlet channel and the outlet channel can be diverted and throttled by means of valves and/or flaps. The one or more fans can be switched on and off and/or the rotational speed of the one or more fans can be changed by means of the regulating unit. The control unit uses predefined data and/or measurement data and signals received and/or accessed by the sensors. The regulating unit can also control the position of the valve and/or flap. The location influencing the air quality in the at least one residential and/or working space is a location in the residential and/or working space where, for example, an event occurs that changes, in particular reduces, the air quality for humans, animals and/or plants. In other words, adverse events affecting air quality occur at locations that affect air quality. The influence can relate in particular to odorous substances, polluting substances

Or gaseous, vaporous, droplet and/or particulate emissions of harmful substances.

As proposed, at least one sensor is arranged in the vicinity of the location where the air quality is influenced. For example, one, two or more sensors can be arranged in the vicinity of a location which influences the air quality, in particular as a combination sensor or a sensor which is evaluated in combination. However, it is also possible to have two or more sensors, each of which is arranged in the vicinity of a different point that influences the air quality. For example, a first sensor may be disposed at a first location while a second sensor is disposed at a second location. By arranging the sensor near a location where the air quality is affected, events affecting the air quality act directly on the sensor. But such events may also act indirectly on the sensor. Further, such an event may act on and be recognized by the sensor without a significant time delay before the user can perceive the event. This may mean, for example, that the sensor is arranged at most about 1 or 2 meters from the location where the air quality is affected. Alternatively or additionally, this may also mean, for example, that the emissions influencing the air quality act on the sensor substantially undiluted or only weakly diluted. Alternatively or additionally, this may also mean, for example, that an event which influences the air quality is detected by the sensor at most 10 seconds after its start. In the following, unless specifically indicated otherwise, the concept "sensor" refers to at least one sensor arranged in the vicinity of a site where the air quality in the at least one living and/or working space is affected.

An advantageous embodiment of the system is characterized in that the at least one sensor is selected from the group of: air quality sensor, air turbidity sensor, air humidity sensor, air temperature sensor, particle sensor, VOC sensor, contact sensor, touch sensor, proximity sensor, pressure sensor, combination sensor. Such sensors sense air quality, air turbidity, air humidity, air temperature, particles in the air, volatile Organic Compounds (VOCs) in the air, mechanical contact, body touch, body proximity, and/or pressure. The combined sensor is capable of sensing more than one parameter. Such sensors sense, for example, quantitative values, such as measured values, and/or qualitative results that are below or above a predefined limit value. The sensor reports the measurement values or results to or is accessed by the regulating unit. The connection between the sensor and the regulating unit can be wired or wireless in an electrical, electronic and/or purely information-technology manner.

A further advantageous embodiment of the system is characterized in that the location affecting the air quality is selected from the group: kitchen, cooking location/hob, workroom, work location, bathroom, toilet, heating room, heating location. In such locations, odor, pollutant or harmful substances, which consume air and are to be discharged via systems for ventilation and/or exhaust, are emitted in large quantities. The location influencing the air quality is in particular a dwelling and/or a working space or a defined region and/or a defined position in a dwelling and/or a working space.

A further advantageous embodiment of the system is characterized in that the at least one sensor is assigned to a cooking position, a kitchen hood, a work position, a shower, a toilet seat and/or a toilet flushing device. In the space-assignment aspect, an air quality sensor or VOC sensor arranged in or beside the kitchen worktop (part of the cooking location) senses changes in the air composition, and a pressure sensor senses mechanical operation with the cooking meal. An air humidity sensor or an air temperature sensor arranged beside the cooktop or a contact sensor or a pressure sensor arranged integrated in the cooktop senses the utilization of the cooktop. An air quality sensor, an air turbidity sensor, an air humidity sensor, an air temperature sensor or a VOC sensor arranged on or in the kitchen hood senses a change in a component composition of air rising into the kitchen hood and thereby senses a cooking process causing emissions; the touch sensor senses manual touch of the kitchen range hood; the proximity sensor senses proximity or a special gesture of a user. An air turbidity sensor, an air humidity sensor or an air temperature sensor arranged beside the shower room senses fog rising during showering, moisture formed or heat. A VOC sensor disposed beside the toilet senses emissions utilized with the toilet. A contact sensor, a touch sensor or a pressure sensor arranged on or under the toilet seat senses the seated person. A touch sensor or touch sensor disposed on the toilet flush device senses flushing of the toilet. Common to these embodiments is that events affecting the air quality act on the sensor directly or indirectly and without significant time delays.

In terms of purpose assignment, these sensors can be assigned, in particular also primarily, to devices which are different from the system for ventilation and/or exhaust and/or to purposes which are different from ventilation and/or exhaust. In addition to these different assignments, the sensors are also assigned to and/or connected to a system for ventilation and/or ventilation, and/or in addition to these different purposes are also assigned to ventilation and/or ventilation. For example, a sensor assigned to a cooking or operating position can be used, in particular also primarily, to activate the lighting device of the cooking position. For example, a sensor, in particular a contact or touch sensor, assigned to the kitchen ventilator can be used, in particular also primarily, for manually activating the kitchen suction device, for example in a circulating air operation or in a ventilation operation. This corresponds to the connection of an air quality sensor assigned to the kitchen ventilator to the control device of the ventilation system. The sensor associated with the shower or toilet can be used, for example, in particular also primarily for switching on a music player in the bathroom or toilet. The sensor assigned to the toilet seat can be used, for example, in particular also primarily for heating the toilet seat. Sensors, for example contact sensors or touch sensors, assigned to the toilet flushing device can also be used to trigger the flushing process of the toilet. By way of an exemplary primary use of the sensor for activating a lighting device, a kitchen suction device, a music player, a toilet seat heating device or a toilet flushing process, a secondary or parallel use of the sensor for the early detection of an imminent or just started odor substance emission, pollutant emission or pollutant emission is achieved.

The invention also relates to a method for ventilating and/or discharging at least one living and/or working space with a system for ventilating and/or discharging air, comprising one or more inlet channels, one or more outlet channels, one or more fans, a control unit for controlling the fans, and one or more sensors connected to the control unit.

A method for ventilating and/or venting at least one residential and/or working space is proposed, wherein the regulating unit activates at least one fan and/or increases the fan speed when a sensor arranged in the vicinity of a location influencing the air quality in the at least one residential and/or working space reports a poor air quality to the regulating unit.

The method ensures a determined air quality required or desired for the comfort and/or health of people, animals and/or plants in the at least one residential and/or working space. Central or non-central, regulated or controlled ventilation facilities with or without heat recovery are used for this purpose. Fresh air, for example external air or an external air-circulating air mixture, flows into the space via the intake channel. Used air, for example gaseous, vaporous, droplet-shaped and/or particulate exhaust air with odorous, polluting or harmful substances, in particular air of poor quality, flows out of the space through the exhaust duct. The fan causes air movement and flow through the passageway and space. The fan operates in on/off operation and/or speed-regulated operation. The magnitude, in particular the magnitude, of the air volume flow delivered by the fan varies with the rotational speed of the fan. The air volume flow in the channel system formed by the inlet channel and the outlet channel can be diverted and throttled by means of valves and/or flaps. The one or more fans are switched on and off and/or the rotational speed of the one or more fans is changed by means of the regulating unit. The control unit uses predefined data and/or receives measurement data and signals from the sensors or accesses the sensors. The regulating unit can also control the position of the valve and/or flap. As proposed, in the method, when a sensor arranged in the vicinity of a location which influences the air quality in the at least one residential and/or working space reports poor air quality to the regulating unit, the regulating unit activates the at least one fan and/or increases the fan speed.

This means that: events that affect the air quality act on and are recognized by the sensors, directly or indirectly and without significant time delay; the control unit intervenes in the operation of the system for ventilation and/or ventilation without a significant delay, in that the air volume flow, in particular at the location of reduced air quality, is increased without a significant time delay and the required or desired air quality is reestablished in the shortest time. Here, no significant time delay represents a very short delay in the range of a few seconds, for example 10 seconds, between the start of an event that influences the air quality and the effective increase in the air volume flow.

An advantageous embodiment of the method is characterized in that the regulating unit regulates at least one component assigned to the at least one intake duct and/or the at least one exhaust duct when a sensor arranged in the vicinity of a location which influences the air quality in the at least one residential and/or working space reports poor air quality to the regulating unit. The magnitude of the air volume flow in the at least one living and/or working space is thereby changed, in particular increased. Such devices are used to vary and control the air volume flow in the intake and/or exhaust duct, in particular by dividing, merging, mixing, throttling and/or blocking, and may be, for example, flaps, slide valves or valves. By variably distributing the total air volume flow circulated by the system to the intake and/or exhaust air channels and to the living and/or working spaces, the size of the individual air volume flows in the living and/or working spaces in which events that influence the air quality occur and thus in particular at points where the air quality is reduced can be increased in a targeted manner.

A further advantageous embodiment of the method is characterized in that when a sensor in the vicinity of the location in the at least one residential and/or working space where the air quality is affected reports a good air quality to the regulating unit, the regulating unit deactivates the at least one fan and/or reduces the fan speed, and/or resets the at least one valve and/or flap of the channel system. It is thereby ensured that, after the desired state with at least sufficient air quality has been reestablished, the system returns to the basic state in which the fan returns to its design rotational speed and/or in which the distribution of the total air volume flow circulating through the system to the individual habitation and/or working spaces returns to its design point.

A further advantageous embodiment of the method is characterized in that the regulating unit deactivates the at least one fan and/or reduces the fan speed and/or resets the at least one valve and/or flap of the channel system if the actual operating time of the activated fan and/or of the fan operating at the increased fan speed is greater than a predeterminable maximum operating time. It is thereby ensured that the fan is not operated for too long at the increased rotational speed and that the noise and/or energy consumption with the increased rotational speed does not take place for too long.

Drawings

An exemplary embodiment of the present invention is shown in fig. 1.

Detailed Description

Fig. 1 schematically shows a central system 1 for ventilating and/or venting at least one residential and/or working space 2. Alternatively, the invention also includes non-central ventilation and exhaust systems. Five living and/or working spaces 2 (including corridors, bathrooms, kitchens) are currently disclosed, which together constitute one housing. For greater clarity, the components of the system 1 are shown alongside the residential and/or work space 2, but they may in fact be located within the residential and/or work space. The system 1 comprises a plurality of inlet channels 3 for supplying fresh air into the space 2, a plurality of outlet channels 4 for discharging used air from the space 2, a fan 5 for conveying and circulating air, two means 9 for changing the size of the air volume flow and/or for changing the division of the total air volume flow into at least two single air volume flows, a regulating unit 6 for operating the fan 5 and the means 9. A sensor 7 is currently shown, which is arranged near a site 8 affecting the air quality in the residential and/or working space 2. This location 8 is currently a kitchen 8.1, more precisely a cooking location 8.2. Instead, the location 8 can also be, for example, a workplace/study, a work station, a bathroom 8.4 with shower and/or toilet or a heating room, a heating station (place for placing a heating appliance). The illustrated sensor 7 is intended to be an air humidity sensor arranged in or on the kitchen hood 8.3, which recognizes a reduced air quality resulting from a cooking operation in terms of an increased air humidity following the cooking operation. Alternatively, the sensor 7 can also be an air quality sensor, an air turbidity sensor, an air temperature sensor or a combined sensor, for example a combined air humidity/air temperature sensor; all these sensors can identify in this way the reduced air quality caused by the cooking process. Alternatively, the sensor 7 can also be a contact sensor, a touch sensor or a proximity sensor, which detects the opening or touching of a kitchen hood or a predefined gesture of a user. The sensor 7 is connected to the control unit 6 of the system 1 by means of a connection 10, which transmits the measured values or the measured signals, for example a wired or wireless connection. The fan 5 and the regulating unit 6 can be combined into one structural unit.

The sensor 7 is assigned to the kitchen ventilator 8.3, for example. The sensor 7 is here a component comprised by the kitchen ventilator 8.3, the primary function of which is to identify the cooking process and the consequent reduced air quality and then to switch on the kitchen ventilator 8.3. This can be done, for example, in a circulating air operation, in which cooking steam rising from the cooking point 8.2 is sucked away by the kitchen ventilator 8.3, mixed with the room air of the kitchen and blown back into the kitchen in diluted form.

However, sensor 7 also reports the poor air quality detected at cooking position 8.2 to control unit 6 of ventilation and exhaust system 1. Subsequently, the regulating unit 6 activates the fan 5 or increases the rotational speed of the fan 5. And/or the regulating unit 6 actuates one or both means 9 in the

air ducts

3, 4 and thus increases the volume flow of air circulating in the kitchen 8.1, so that the used air is sucked away. The signal path from the event starting at point 8, which adversely affects the air quality, via sensor 7 and control device 6 to fan 5 and/or to means 9 is extremely short and can be overcome in a minimum of time. The fan 5 and/or the means 9 smoothly carry out the required speed change or position change, so that the used air is removed and the required or desired air quality is reestablished in a very short time.

If a sensor 7 in the kitchen 8.1, in particular in or on the kitchen extractor hood 8.3, reports a good air quality to the control unit 6, the control unit 6 deactivates the at least one fan 5 or reduces the fan speed and/or resets the means 9 back into the normal position again, so that the ventilation and exhaust system 1 again operates at the design point.

Alternatively or additionally, if the actual operating time of the fan 5, which is activated and/or operated at the increased rotational speed, exceeds a specifiable maximum operating time, the control unit 6 deactivates the fan 5 and/or reduces the fan rotational speed and/or resets the means 9 again into the normal position, so that the ventilation and exhaust system 1 again operates at the design point.
