    System for regulating the climatic conditions of a building, as well as the method and application.
    A system for regulating the climatic conditions of a building such as a stable adapted to house animals such as pigs or poultry / chickens, which system comprises a temperature meter for measuring an air temperature TO, a humidity meter for measuring humidity RFO and a fan unit for regulation of an airspeed VO in the animals' living area.
    The invention also relates to a method for regulating the climatic conditions in a building such as in a barn adapted to house animals such as pigs or poultry / chickens, which method utilizes a temperature meter for measuring temperature TO a humidity meter for measuring humidity RFO and a a fan unit for controlling the average air velocity VO in the animals 'living area and that the method comprises a visual inspection of the animals' comfort state.
    Animals such as chickens and pigs staying in stables are subject to temperature fluctuations, which can cause discomfort in the animals. This discomfort can manifest in abnormal behavior and the animals' food intake is reduced and thus their growth rate. The growth rate is thus directly dependent on the climatic conditions being experienced as optimal by the animals.
    However, the optimum temperature, as experienced by the animals, does not depend solely on the exact air temperature. In addition to the exact air temperature, wind velocity / air velocity and relative humidity are also included, which affect how the temperature is actually experienced by the animals. The experience of the climatic conditions is different for the animal species, and within the same species the experience of the optimum temperature as a function of the age of the animal changes. The experience of the climatic conditions also depends on humidity and air velocity in the animals' living zone. A given temperature is experienced higher the higher the humidity, while a higher air velocity in the animals' living area gives rise to a given temperature being experienced as a lower temperature.
    The systems available are only capable of correcting the experienced temperature by manual operation and by observing that the animals appear to be discomfortable. It is read, as mentioned, that their food intake is too low compared to an optimal intake. This observation will cause the temperature of the barn to be adjusted. Alternatively or simultaneously, the fans will be turned up or down to change the air flow.
    Such regulation will generally be experienced too cold or too hot by the animals and therefore the optimal growth rate cannot be achieved.
    From wo 2005082t34 A1 there is known a system for regulating the climatic conditions in a building such as a barn adapted to house animals such as pigs or poultry / chickens, which system comprises a temperature gauge for measuring air temperature, a humidity meter for measuring a humidity , as well as a fan unit for controlling the average airspeed in the living area of the animals, the system comprising a data memory unit with data applicable to the species and age of the animals, and wherein the system comprises a computer comprising a program for calculating an optimum experienced temperature TP which the optimum temperature experienced is a function of the data bank's data applicable to the animals 'age and species, as well as a function of the measured temperature, the measured humidity and the air velocity in the animals' living area.
    It is thus the object of the present invention to provide an alternative system and method in which an automatic regulation of the temperature experienced by the animals takes place and where the regulation is based on a construction / method / model involving various components of importance. for the experience of temperature. The air velocity in the living area of the animals can be increased / decreased, it can be humidified, thereby changing the temperature of the air.
    The object is achieved by a system of the above stated, and wherein the system also includes a scale for adjusting the system to a selected experienced temperature T1, and that a control unit is arranged to control the humidity and / or temperature and / or air velocity in the animals' living area. , by which regulation the calculated optimum experienced temperature T1 becomes identical to the experienced temperature set T1 on the scale. Since the system comprises a database of data applicable to the species and age of the animals, and includes a computing unit / processor unit comprising an algorithm for calculating an optimum experienced temperature Te, which experienced optimal temperature Te is a function of the database data applicable to the age and species of the animals, as well as a function of the measured air temperature TO and the measured humidity RFO and air velocity in the animals 'living area, and that a control unit is arranged to control the humidity and / or temperature and / or air velocity in the animals' living area, it can be ensured that the calculated optimum experienced temperature Te becomes identical to the experienced temperature set T1 on the scale.
    The object is also achieved by a method of the introduction stated in the introduction and also that a data bank comprising data for the animal species and as a function of the age of the animal and that a scale for optimal temperature is set to an optimal comfort state for the animals as a result of the visual inspection which activity of the ventilator unit is changed, whereby the average air velocity is changed and / or an humidifier is activated, whereby the relative humidity and temperature are changed, at which the calculated optimum experienced temperature Te becomes identical to the experienced temperature set on the scale T1.
    Comfort mode means the level of comfort that the animals may be in, ie. whether they are outside their comfort zone or within their comfort zone. To the extent that they are outside the comfort zone, a regulation according to the invention will cause the climatic conditions to be changed by a single setting on the system so that the animals enter the comfort zone and thereby have optimal growth conditions.
    In this way, it is thus possible, by a single setting on a climate controller, to regulate the climatic conditions in the building so that it is experienced optimally for the animals.
    When the animal handler enters a barn, it is possible for him to recognize whether the animals are in optimal climatic conditions. It is recorded by considering their behaviors including eating and physical activity. If he recognizes that the conditions are not optimal, he sets by a handle or the like a scale on the climate controller to an experienced temperature that he knows the animals will thrive optimally. The system also includes a data bank for the particular animal species where associated values for optimal air temperature and humidity is encoded as a function of animal age. This is empirical data. The system is pre-programmed to be able to select the correct associated values, manually setting the database to the appropriate and correct value for the age of the animals when the animals are first entered into the barn. Thereafter, the optimal values will automatically be used as a function of time from the first day, the first day being the starting level.
    The processor unit will then regulate the average air velocity in the residence zone by activating fans located at appropriate locations in the building, and at the same time or alternatively an apparatus will emit atomized water particles, for example, through nozzles, which will cool the air. This changes the humidity and the actual temperature we simultaneously lower as a result of the evaporation. Also, heaters can be located in the building.
    The processor unit adjusts to humidity, temperature and wind speed using an algorithm such that the optimum experienced temperature becomes identical to the set experienced temperature. It is obtained by a calculation algorithm which comprises
    Te = T0 * (a + b * RF0AE) -c * (x-T0) * (V0-e)
    Where: a: is a constant E: is a constant e: is a constant b: is a constant x: is a temperature constant c: is a cold sensor value (c is dependent on the age of the animals) VO: is the air velocity in the animals' living area, which can measured or calculated.
    Tea: is the optimum temperature experienced TO: is the measured air temperature.
    RFO: is measured humidity
    In other words, the user only has to regulate on a handle to activate the parameters that affect the animal's well-being namely: humidity, air velocity in the animal's living area, and air temperature.
    In a further convenient embodiment according to claim 2, the control unit of the system is arranged to control the fan unit, at which the air velocity VO in the animals' living zone is changed, at which the calculated optimum experienced temperature Te becomes identical to the scale temperature experienced T1.
    The controllers are actually built into the processor and are a device that activates the fan unit fans so that the wind speed changes; Selected experienced temperature is the temperature at which the person or system knows that the animal in question thrives and is an empirical size.
    In a further convenient embodiment according to claim 3, the system comprises a water atomizer, which system is adapted to control a water atomizer at which atomization the humidity changes from RFO to RF1.
    The evaporating agents comprise the supply of aerated water particles to the stable air. The water particles evaporate in the stable air, which cools the air and the temperature changes. It is possible in extreme cases, in this way, to lower the temperature by up to 20 degrees C.
    In a further convenient embodiment, the fan unit comprises several fans located in the building.
    In a further convenient embodiment, fan units comprise a unit by which the average air velocity is calculated and / or measured.
    In a further convenient embodiment according to claim 4, the data bank comprises data for optimum temperature Tx and for optimum humidity RFx as a function of an animal's age and species.
    In a further convenient embodiment according to claim 5, the system comprises a cooling sensor for establishing a cold sensor value c, which value is included in the calculator / processor to obtain the optimum experienced temperature.
    In a further convenient embodiment according to claim 6, the system comprises the cold sensor value c arising from the fact that the cooling sensor is a physical cold sensor for measuring cooling near the zone in which the animals reside, which cold sensor value c is a parameter included in the calculation algorithm in the processor unit. .
    In a further convenient embodiment according to claim 7, the cold sensor value c is obtained by the cooling sensor being a virtual sensor for providing an empirical value for cooling near the zone in which the animals reside. The cold sensor value c is a parameter included in the calculation algorithm in the processor unit.
    The invention also relates to a method as previously described and according to claim 8.
    In a further convenient embodiment of the invention according to claim 9, the method comprises activating a setting on a scale characteristic of the species and the average age of the animals.
    The setting is physical for the first time, with the animal handler adjusting the scale according to the age of the animals, and then the data is automatically adjusted as a function of time.
    In a further convenient embodiment, the method comprises that the data bank's data comprise coherent values for optimum temperature Tx and optimum humidity Rx for the animals in the building and as a function of the nature and age of the animals.
    In a further expedient embodiment, the activation comprises a setting on a scale characteristic of the animals' species and average age and includes coherent temperature and humidity values.
    The invention also relates to the use of a system according to the invention for practicing the method according to the invention.
    The invention will now be explained in more detail with reference to the drawing, in which
    FIG. 1 shows a diagram of a system according to the invention.
    FIG. 2 shows a diagram where the optimally experienced temperature is plotted as a function of the air temperature at a given air velocity and humidity for a selected animal of a given age.
    FIG. 3 shows a building where the system according to the invention is arranged.
    FIG. 1 shows a diagram of a system 1 according to the invention. It comprises an apparatus 6 in which a selected perceived temperature T1 is set from a temperature scale. This setting includes one setting and no more and is based on the recognition of whether or not the animals in a stable appear to be in their climatic comfort zone. It is known that a temperature at very high humidity feels higher than the same temperature at a lower humidity. In this way, the concept of an optimum experienced temperature Te arises, which will thus be a function of the measured temperature, the measured humidity, a cold sensor value c for the individual animal, which is a function of the age of the animals and the air velocity in the building. What is unique about this system is that it is only necessary to acknowledge the comfort of the animal, adjusting it to the perceived temperature that is known will give the animal optimal comfort / optimum temperature experience, and that this setting requires only a single scale / button adjustment and not as in the known systems in which all three parameters must be set individually.
    The selected experienced temperature T1 is set on the apparatus 6. This provides input to the remaining part of the system 1, which comprises a temperature meter 3 which measures and records the air temperature in the building, an air humidity meter 4 which measures and records the relative humidity. In addition, the system 1 contains a data bank 7 which has data for the comfort temperature and comfort humidity of the animal, as a function of the age and species of the animal.
    The data for temperature humidity as well as associated values for humidity RFx and temperature Tx, as a function of age of the animals, are sent to a processor unit 8 which includes an algorithm for calculating the optimum experienced temperature Te, which is a function of said parameters. The optimum experienced temperature Te is also a function of the air velocity in the animals' living area, which is measured / calculated by a fan unit 5 with a suitable apparatus / input 14 according to known principles. In addition, a cold sensor value c is included in the algorithm. The cold sensor value c that the processor unit receives from a virtual or physical cooling sensor 15,16 is a function of the air velocity VO in the animals' living area. The values of the processor unit 8 cause a control unit 10 for regulation to the optimum experienced temperature Te to be activated, by controlling TO and / or RFO and / or VO to obtain Te. The regulation may be that fan unit 5, which may comprise several fans 13 located at different locations in a building, is activated thereby changing the temperature and / or there may be a change in humidity by activating an apparatus 12 for evaporating water. For example, if water dust is sprayed into the building, the humidity will rise and at the same time the air temperature will fall. The algorithm in the processor unit takes into account the various parameters and will set the air velocity, the actual temperature and the actual humidity relative to each other so that the optimum experienced temperature is obtained.
    The system will continue to automatically adjust the parameters in relation to each other so that the set optimum experienced temperature is achieved. Thus, a closed loop system has been obtained for setting the temperature to an optimum experienced temperature.
    As soon as it is recognized that the comfort zone is not right for the animals, a new value is set on the scale and the system automatically adjusts the parameters mentioned so that the optimum temperature is adjusted to the set temperature.
    Figure 2 shows the relationship between optimum perceived temperature and the actual temperature in a building. The data is for broilers with a age of 5-7 weeks staying in a barn at a humidity of 20% and a cold sensor value c of 0.15. Out of the x-axis is plotted the temperature in the stable TO and out of the -y axis is the optimum experienced temperature Te as a function of the actual temperature in the building. Curve a represents continuous values at an air velocity of 1 m / s and curve b represents continuous values at an air velocity of 3 m / s.
    Thus, when reading the data for broiler chickens staying in a stable with said constants, where the average air velocity is 3m / s, the optimally experienced temperature will be approx. 23 degrees Celsius when ambient temperature is 30 degrees Celsius. If the air velocity was reduced to 1m / s - at the same conditions otherwise - the optimally experienced temperature will be read to approx. 27 degrees Celsius.
    As mentioned, the parameters are set by a processor unit which regulates according to the data which is otherwise collected in a data unit and data which is otherwise measured / recorded in the stable.
    For broilers, the following coherent data applies to setting the optimum experienced temperature Te, which is used when setting the parameters including air velocity.
    Age (days) Air temperature Humidity Q Celsius% 1 33 50% 7 31.5 50 14 28 60 21 25 65 28 23 70 38 20 80
    FIG. 3, a building 2 shows in particular a stable which at its entrance has placed a control unit 9 for setting the desired experienced temperature on a scale.
    A fan unit 5 is installed in the stable, which here comprises a plurality of fans 13 which provide for regulating the air velocity in the residence zone 2. The fans 13 are located in the ceiling and / or in the walls.
    In addition, the stable also houses a nozzle plant 12 comprising pipes, which pass through the entire barn, through which pipes water flows. The pipes are fitted with nozzles. The nozzles can be actuated, thereby spraying water dust, which increases humidity and which changes the temperature of the barn.
    Said elements may be included in a system 1 according to the invention.
