Definitions
- the invention relates to a sensor for controlling air conditioning systems or ventilation systems based on a perceived air temperature, which is caused by the climate components of air movement, air temperature and heat radiation, including solar radiation, especially in moving means of transport.
- Sensors for controlling air conditioning systems or ventilation systems are necessary in a wide variety of technical solutions for measuring and influencing the perceived air temperature as a detection element of various sizes to be measured.
- sensors of this type are necessary for measuring and controlling the indoor climate, the degree of thermal discomfort, or for measurements to achieve human comfort.
- DE 196 02 085 A1 discloses a method for achieving a comfort temperature in a room and an arrangement for carrying out the method.
- the temperature in the vicinity of a radiator is measured while avoiding direct thermal influence by the radiator.
- the required irradiance is determined by means of electronics, this taking place depending on the distance of the person from the radiator, which must also be detected.
- air temperature, air speed, mean radiation temperature, air humidity, intensity of physical activity and type of clothing only one is recorded in this solution.
- a known temperature sensor is used to determine the temperature, which is not specified in the document. This in no way fulfills the requirements that are currently placed on the elements of ventilation and air conditioning systems that are necessary for control.
- no suitable sensor for detecting the factors for human comfort is disclosed.
- the object of this invention is to provide a device with which it is possible to determine the degree of thermal discomfort in a simple manner without using a data processing system at various adjustable values for the total heat accumulation inside the body. It is a device in which a heatable measuring body for simulating the heat exchange of the human body with the environment and a control circuit for maintaining the temperature of the measuring body at a predetermined value close to the skin temperature of the human body are provided. Part of this device is a measuring body, the size of which can be approximately 20 cm. The inside of the measuring body has a body made of plastic foam, around which an electrical resistance wire is wound.
- the outside of the measuring body is provided with an approximately 1 cm thick layer of heat-insulating material. This layer, together with the regulation of the heating element formed by the resistance wire, ensures that the measuring element has the same ratio between ⁇ d r y (dry heat exchange) and t s (surface temperature) as for a person feeling thermal comfort.
- the measuring body is mounted on a rod, which is supported in a tripod, and preferably in such a way that this measuring body can assume different positions. Because of its size, the solution described above is unsuitable for today's requirements for sensors that are used to control air conditioning and ventilation systems. Cost reasons that lead to a constant reduction in the expenditure for air conditioning and ventilation systems make the use of this solution appear to be very questionable from today's perspective, especially in moving means of transport.
- DE 36 11 084 A1 discloses a measuring device for the variables influencing the room climate, which is a heating device which is surrounded by thermal insulation and to which a temperature sensor is assigned. This temperature sensor is used to record the heat flow from the heating device to the outside.
- the device for assessing the indoor climate known from PS DE 32 05 704 C2 and a device for air conditioning in rooms known from DE 43 15 113 A1 were developed, which already eliminate the aforementioned disadvantages.
- DE 43 15 113 A1 this is done in that the sensor unit (sensor) of a heating / cooling ceiling has a heatable surface which is heated with constant power, and the temperature of which is detected by a temperature sensor, from the output signal of the temperature sensor and as a measure
- the reference variable is formed here for the comfort value determined.
- a device for assessing the indoor climate with a temperature sensing element which has the shape of a defined, flat, meandering area filled with a metal strip with a maximum absorbing side in the infrared, through the normal of which a measuring device provides a spatial measuring range
- Temperature sensing element is determined with a heating element of the temperature sensing element, by means of which a constant heating power is supplied to it by a heating device and which furthermore has an evaluation device for evaluating the variable resistance value of the temperature sensing element.
- the object of the invention is to develop a comfort sensor for controlling air conditioning systems or ventilation systems according to a perceived air temperature, in particular in moving means of transport, for the defined detection of a climate total value which manages to measure comfort parameters without constant heating power and / or constant temperature, is simple to manufacture and its manufacturer Positioning costs is lower in comparison to sensors previously used for this purpose in order to enable efficient use.
- the senor consists of a temperature-dependent resistance track which is applied on both sides to a body which simultaneously forms the insulation layer. Both areas are heated. Both the heat flow emitted to the outside and the temperature of the heated surface float, caused by a constant current supplied to the surface and the respective climatic components. The voltage across the resistor is recorded as the measurement signal, an equivalent temperature of a homogeneous space being assigned to this measurement signal as a comfort reference. Either the temperature difference between the top and bottom or only the temperature of the bottom is constant.
- the senor consists of a temperature-independent resistance track with a separate temperature sensor.
- the resistance track is arranged on both sides of the body forming the insulation layer. Both surfaces are heated in turn.
- a constant current is also specified for heating, as previously mentioned.
- the voltage at the temperature sensor is recorded as the measurement signal, an equivalent temperature of a homogeneous room being assigned to this measurement signal as a comfort reference.
- Another possibility is given by the fact that the upper surface of the sensor is not heated, the upper surface is heated only by the lower surface, but the temperature of the lower surface is kept constant and the measurement signal, which is taken from the upper surface , is assigned an equivalent temperature of a homogeneous room.
- the surface temperature does not have to correspond to the surface temperature of the human skin. It has proven to be advantageous if the resistance tracks are applied directly to a flexible material that serves as a carrier. Due to the flexibility of the material, the sensors can be arranged at precisely the critical points that are important for assessing human comfort. The advantage of this is that these sensors do not interfere. For example, they can also be rolled up with the belt.
- Another design provides for the resistance tracks to be woven directly into the mounting surface without their own carrier (e.g. belt, headrest).
- a compact temperature-dependent resistor instead of a resistor track distributed over the surface.
- a constant heat flow is supplied to or removed from the sensor from behind (omnidirectionally from the inside). This creates a constant temperature difference.
- a heat flow from behind is also negligible in that the sensor is applied to a carrier, preferably a flexible carrier, with low thermal conductivity and penetration depth and is only heated at the top.
- the surface of the sensor has different colors and / or is coated with a substance which has heat-reflecting properties. The sensor can thus be used as a draft sensor.
- FIG. 3 a sensor, the temperature-dependent resistance tracks of which are inserted in foil and which are placed on a body that protects the insulation. layer forms, is applied on both sides.
- the temperature of the upper resistance track Ti is variable.
