    The invention relates to a device and a method for controlling a fresh air supply in a device for cooling, heating and / or ventilation of a building, in which depending on the number of people in the building a person to be admixed to the circulating air of the device F risch air quantity is controlled to thus at least partially produce a predetermined amount of supply air for the building.
    In order to adjust the amount of fresh air for a room of a building as required, it is known from the prior art (DE20102312U1) to count the number of people, for example via a non-contact person detection, and adjust the amount of fresh air depending on this result , Although this allows the amount of fresh air supplied to be matched to a number of people, in practice, however, it turned out that nevertheless an additional amount of fresh air must be taken into account in order to be able to cover the fresh air demand sufficiently. However, to consider an increased proportion of fresh air disadvantageously requires an increased operating cost, for example to compensate for a temperature difference between fresh air and building air. It is also known from DE19847504C1 to measure the CO 2 content of the building air as an alternative to the number of persons. However, an additional amount of fresh air can not avoid such a measurement, especially since different pressure conditions in the device can exert an influence on the amount of actually supplied fresh air and for reasons of operational safety for a compensation may be provided missing amounts of fresh air. -2-
    The invention is therefore based on the object, starting from the above-described prior art, a method for controlling a fresh air supply to improve such that the operating costs for cooling, heating and / or ventilation of a building can be kept small with a more accurate determination of the required amount of fresh air ,
    The invention achieves the stated object with regard to the method in that, depending on the mixing temperature of fresh air and circulating air, the amount of fresh air to be supplied, corresponding to the number of persons in the building, is regulated,
    If, depending on the mixing temperature of fresh air and recirculated air, the amount of fresh air to be supplied according to the number of people in the building is regulated, then a particularly accurate quantity adjustment of supplied fresh air can be ensured over a comparatively simple process step. A predetermined and thus known amount of supply air, which determines the number of persons in the building specific amount of fresh air and temperature measurements of various air components, in particular exhaust air, recirculation and / or room air and outdoor air and / or fresh air, namely a target mixing temperature of the mixed air become. By comparing the mixing temperature of fresh air and circulating air to the desired mixing temperature, a precise control of the fresh air to be supplied can now be made possible in a simple manner. To account for unnecessary additional amounts of fresh air can thus be dispensed with, which not only reduces an expense for cooling, heating and / or ventilating a building, but can also reduce the associated operating costs. In addition, the inventive method is also extremely robust against incorrect supply of fresh air, even if a predetermined amount of supplied fresh air to the device is adjustable, because by their control over the mixing temperature both production-related as well as adjusting in operation deviations in a simple manner can be compensated. Even a quantity of actually supplied fresh air which fluctuates on the basis of different pressure conditions can be compensated according to the invention without an additional amount of fresh air having to be considered standardized. The method according to the invention can therefore reconcile stability with low operating costs and is thus distinguished from the state of the art.
    Simple process conditions can result if the number of people in the building is counted by a counter. Here, especially in shopping malls, a non-contact counting device is distinguished, since it is not perceived by the persons in the building, those entering the building and I or the building, and therefore such a procedure can work in the background without disturbing the persons.
    The accuracy of the method for fresh air supply can be further improved if, in addition, the CO 2 content of at least parts of the building air, the exhaust air and / or recirculated air is taken into account in the regulation of the amount of fresh air to be supplied. In fact, it is possible to deduce the actual oxygen consumption of the persons in the building via the CO 2 content, as a result of which a reduction in the amount of fresh air to be supplied can be made possible even with reduced consumption. The method according to the invention can therefore further reduce the operating costs of the building.
    It is a further object of the invention to improve a device for cooling, heating and / or ventilating a building such that a stable ventilation ensured with sufficient fresh air, the operating costs of the device can be kept low.
    The invention solves this problem by the fact that the control device is connected to the temperature sensor for taking into account the mixing temperature of fresh air and circulating air when controlling the valve depending on the number of people in the building. · · · · · · · · · · · · · · · · · · · · · · · · ·.

    If the control device connected to the temperature sensor for taking into account the mixing temperature of fresh air and circulating air when controlling the valve depending on the number of people in the building, then the fresh air to be supplied in the amount can be adjusted precisely in the amount because of the temperature inference on the mixing temperature can be compensated for any deviations of the device. The device is therefore particularly stable in the supply of a sufficient amount of fresh air. In addition, a provision of such a scheme is structurally easily solvable, so that a cost-effective device can be created, which can also be characterized by reduced operating costs due to a more accurate supply of fresh air.
    The operating costs of the device can be further reduced if a sensor for measuring the C02 content is provided at least parts of the air of the building, which is connected to the control device. In fact, the CO2 content can be used to deduce the actual quality of the building air and, if necessary, the proportion of fresh air to be reduced.
    The invention may be particularly characterized in that a mixing temperature of fresh air with circulating air is used in a device for cooling, heating and / or ventilating a building for improved control of the amount of fresh air to be supplied according to the number of people in the building, which benefits have already been explained in detail above.
    In the figure, for example, the invention is illustrated in more detail using an exemplary embodiment.
    The device 1 shown for cooling, heating and / or ventilation of a building 2, for example, has an air duct 3, with which the building air 4 of the building 2 can be influenced. Thus, this air duct 3 has at least one exhaust air opening 5 projecting into the building air 4 for extracting exhaust air 6 from the building 2 and an inlet air opening 5 'for supplying supply air 7 into the building 2. • * • · «« < ·······································································································.
    Based on the amount of extracted building air 4 or exhaust air and supplied supply air 7 can now be set, for example, the air quality in the building 2, which may change, inter alia, by the oxygen consumption of the building located in the building 2 and not shown. To improve the air quality, the supply air 7 can be supplied with a corresponding fresh air 8, since the device has a fresh air duct 9 opening into the air duct 3. Fresh air 8 can be mixed with circulating air 10 of the air duct 3, for example, to improve the oxygen content and the air quality of the building air 4. In order to adjust the amount of supplied fresh air 8, the fresh air guide 9, a valve 11 in the form of a flap. A control device 12 is connected to the valve 11, and controls the open position or closed position of the valve 11 in dependence on the number of people in the building. In addition, located in the air duct 3, a temperature sensor 13, with which the temperature of the mixed fresh air 8 circulating air 10 is measured. The measured temperature of the temperature sensor 13 is used for temperature control of the supply air 7.
    According to the invention, however, the measured temperature of the temperature sensor 13 can also be used for improved control of the amount of fresh air 8 to be supplied, whereby increased stability and low operating costs of the device 1 can be made possible. Namely, the temperature sensor 13 is connected to the controller 12 for taking into account the mixing temperature of fresh air 8 and circulating air 10 in controlling the valve 11 depending on the number of persons located in the building 2.
    Thus, for example, by sensors 13, 14 and 15, the respective temperature of circulating air 10, fresh air 8 and mixed with fresh air 8 circulating air 10 are measured. The amount of supply air 7 for the building 2 is known or is determined by the device 1 and / or exist for this purpose various legal requirements, for example, 30 m3 of air per square meter of the building 2. The amount of supplied fresh air 8 can now on the number of For example, for each person, 40 m3 of fresh air per hour is provided for each person. About the known amount of the predetermined supply air 7, which depends on the number of -6-
    Person calculated amount of fresh air 8, and the consideration of temperatures, such as fresh air temperature, exhaust air temperature, etc., now the target mixing temperature of circulating air 10 and fresh air 8 can be calculated or closed. Depending on the difference between the calculated desired mixing temperature and the measured temperature at the temperature sensor 13, it can now be ascertained whether the amount of fresh air 8 supplied, which is determined by the number of persons in the building 2, is correct. With a corresponding regulation of the valve 11, a readjustment of the measured temperature at the temperature sensor 13 to the desired mixing temperature can now be created. The amount of supplied fresh air 8 is precisely adjustable in a structurally simple manner. Thus, among other things, fluctuations in the supply of fresh air due to undesired pressure conditions in the device 1 can be compensated. An improved stability of the device against operational fluctuations can thus be achieved. In addition, so that the operating costs can be reduced, for example due to the energy consumption of the heating and / or cooling register 17 for controlling the supply air 7, whereby the device can be particularly suitable for buildings such as shopping centers.
    In order to further reduce the operating costs, a sensor 18 for measuring the CO 2 content is provided at least parts of the air of the building 2, which is connected to the control device 12. This sensor 18 is provided in particular in the region of the exhaust opening 5 of the device 1 in order to be able to provide a particularly accurate measurement.
    The number of persons located in the building 2 is counted by a counter 19 operating counter to the persons without contact. This counter 19 is connected to the control device 12 for announcing the number of persons and the related consideration in the regulation of the fresh air supply.
    The device also has a valve 20 for controlling the amount of exhaust air 21. In addition, a fan 16 is provided in the leadership of the supply air 7.
