Description

[0001] A device for climate control in a downpipe, a system for climate control in a house water drainage system and a method for controlling the climate in a downpipe

[0002] TECHNICAL FIELD

[0003] The present disclosure relates to a device for climate control in a downpipe, a system for climate control in a house water drainage system and a method for controlling the climate in a downpipe. More specifically, the disclosure relates to a device for climate control in a downpipe, a system for climate control in a house water drainage system and a method for controlling the climate in a downpipe as defined in the introductory parts of the independent claims.

[0004] BACKGROUND ART

[0005] Many houses and buildings are constructed with pitched roofs that prevents the accumulation of water on the roof. A water collecting system, such as a rain gutter can be mounted at the lower extremity of the roof. The purpose of the rain gutter is to catch water which runs off the roof and channel it to a downpipe, from with the water can be discharged to a desired location.

[0006] In the time of the year when snow on roofs start to melt, the water is collected in the rain gutters and discharged. However, in certain weather conditions, for example when the temperature is below 0°C and the sun is shining on the snow on the roof, the snow start melting. The water that is collected by the rain gutter is channelled to the downpipe where it can freeze to ice, since the downpipes are colder than 0°C. The ice prevents the melted water to be discharged from the roof. The water that is prevented from being discharged can also freeze and break the downpipes. Since the water is not discharged from the rain gutter, icicles can start to form at the rain gutters and fall down and cause injuries on people walking below.

[0007] Today's solutions to prevent ice from forming in downpipes is to install heating cables in the downpipes. The heating cables uses electricity to create heat that prevents the formation of ice.

[0008] Another solution, known from CH243532 A, uses a heater that is arranged in the interior of the downpipe in order to prevent ice from forming in the downpipe. A problem associated with the solution is that not enough climatization is achieved at the same time as the inside of the down pipe is kept clean, such that it will not catch debris such as leaves I summertime when heating is not on.

[0009] SUMMARY OF THE INVENTION

[0010] A problem with today's solution is that the heating cables are exposed to the environment, which increases the risk of failure of the heating cables. Thus, there is a need for a heating system that reduces the risk of failure.

[0011] Another problem is that the power in the heating cable can be too low to prevent formation of ice in the downpipe. There is thus a need to develop an improved heating system which reduces the risk of formation of ice in a downpipe or the formation of icicles in the rain gutter.

[0012] Another problem with using heating cables is that the energy consumption may be high. Thus, there is a need for a heating system that is more energy efficient.

[0013] Another problem is that installing heating cables often requires a person to go high up on the building and install the cable from above. Thus, there is a need for a system that optionally may be installed at a lower height if so required.

[0014] Another problem is that heating cables are passive, any problems which may occur regarding for example leaves that gather in the head pipe cannot be detected or cannot be removed by the cable.

[0015] Another problem with heating cables is that the installation of these is made by applying the cable inside the downpipe. This will pose a problem int that leaves, and other unwanted objects may become tangled up with the cable. This in turn will stop the flow of water in the downpipe and then give problems of water not running or even forcing itself out in joints or over the top, which leads to facades being damaged etc. And if a cable stop of debris occurs, the cable may have to be cut and replaced and even the downpipe itself in order to clear the pipe.

[0016] It is thus an object to provide a clean inside of the pipe, such that debris may pile up by the heating or climatization added.

[0017] It is an object of the present disclosure to mitigate, alleviate or eliminate one or more of the above-identified deficiencies and disadvantages in the prior art and solve at least one of the above-mentioned problems. According to a first aspect there is provided a device for climate control in a downpipe, the device comprises a fan for creating an airflow in the downpipe, wherein the fan is configured to be mounted at an opening at the downpipe wall of the downpipe, wherein the opening is arranged at a pipe section of the downpipe.

[0018] It is advantageous to mount the device with a fan at an opening in the downpipe since an effective air distribution that prevents the formation of ice in the downpipe is achieved. Also, climate control provides for smaller light objects may be removed, such as smaller number of leaves etc. Also, climate control may be very energy efficient, for example when the sun is shining on a section of the downpipe, the climate control may arrange for air with higher temperature is moved to a section of the pipe where ice is forming. And further as the mounting is made in the downpipe wall, the inside of the downpipe is kept clean.

[0019] According to some embodiments, the device comprises a mounting element, configured to be mounted at the opening in the downpipe, preferably there is also comprised a cover element, releasably attached to the mounting element.

[0020] The cover element may be removable in order to facilitate maintenance of the fan or other parts of the device.

[0021] According to some embodiments, an air inlet is arranged at the cover element, wherein the air inlet is fluidly connected to the mounting element, wherein the air inlet is arranged with a protective mesh.

[0022] By arranging the air inlet with a protective mesh, the risk of rain, snow or dirt entering the device is reduced, thereby increasing the lifetime of the device.

[0023] According to some embodiments, an air outlet is arranged at the mounting element, wherein the air outlet is fluidly connected to the fan and fluidly connected to the opening in the downpipe for creating the airflow in the downpipe.

[0024] By arranging the mounting element with an air outlet, the airflow in the downpipe is facilitated, which reduces the risk of ice forming in the downpipe.

[0025] According to some embodiments, a heater is arranged at the device and fluidly connected to the fan, preferably the controller is arranged to control the heater.

[0026] By arranging a heater at the device, the air is heated before entering the downpipe. The heated air further reduces the risk of ice forming in the downpipe. According to some embodiments, the device is removably attached to the outside of the downpipe with a screw clamp device, and / or rubber attachments, and / or pipe clamps, and / or magnets, and / or a hook and loop attachment, and / or a cable tie attachment, and / or pop rivets, and / or screws, and / or adhesive.

[0027] To facilitate removal and mounting of the device, the device is removably attached to the outside of the downpipe. Since the device is removably attached, the device can easily be removed for maintenance. Further, since the device is removably attached, the device can be removed during the time of the year when there is low risk of ice formation in the downpipe, which reduces the risk of theft or damage of the device.

[0028] According to some embodiments, the device is attached to the outside of the downpipe by welding, and / or a further fastening device.

[0029] By welding the device to the outside of the downpipe, a secure mounting of the device on the downpipe is achieved, which lowers risk of theft or damage of the device.

[0030] According to some embodiments, the device comprises a sensor for measuring climate data, a controller arranged to receive the climate data from the sensor and to control the device based on the climate data.

[0031] By adapting the device with a sensor for measuring environmental data, a more energy efficient device is achieved.

[0032] According to some embodiments, the device comprises a communication device for remote control of the device, preferably said remote control is arranged as a downloadable user interface on a mobile device.

[0033] By providing the device with a communication device, an even more energy efficient device is achieved. By remotely controlling the device, the decision when to start the fan and the heater can be adjusted frequently. The device can also be activated or deactivated in an easy manner without having to be present at the device.

[0034] According to some embodiments, the fan is an electric fan.

[0035] An advantage of using an electric fan is that electric fans consume relatively low amounts of energy. Another advantage is that electrical fans can be equipped with variable speed settings, enabling precise control over airflow based on the specific heating requirements, which leads to optimized climate control and energy savings. According to some embodiments, the device comprises an electric grid interface, preferably in the form of an electric cable, for powering said device.

[0036] By arranging the device with an electric grid interface, an easy connection to the electric grid is achieved, resulting in an easy installation of the device at the downpipe is achieved.

[0037] According to some embodiments, the heat in the heater is produced by means of an electric element.

[0038] The electric element allows for precise regulation of heat output, enabling better temperature control and maintaining consistent heating conditions as needed. Another advantage is that electric heating elements typically have a compact form factor, which allows for more streamlined and space-saving heater designs.

[0039] According to some embodiments the device is arranged for a dual heating capability by also including control of a heating cable for direct heating of at least a section of the down pipe, preferably the heating cable is extending below the device.

[0040] The device being in general mounted at a certain height above the outflow opening of the down pipe. For example, for security reason, such that a person walking by will not hit the device and fall. Thus, the lower end section of the down pipe, may not be heated as easily as the upper section above the device. For this reason a shorter cable going downwards may optionally help further improving the heating of the down pipe.

[0041] According to some embodiments the device is arranged such that the heating cable is directly connected to the device.

[0042] By directly connecting the heating cable to the device, no extra power arrangements for the heating cable will be needed and the power cable powering the device, may be used also for the heating cable.

[0043] According to a second aspect there is provided a system for climate control in a house water drainage system comprising at least one downpipe, wherein a device according to the first aspect is mounted at the at least one downpipe.

[0044] By mounting a device in each downpipe of a house water drainage system comprising at least one downpipe. A more robust house water drainage system is achieved. According to some embodiments, the system comprises a communication device for communication between the system and each device in the system, for remote control of each device.

[0045] By arranging the system with communication devices, each device can be controlled individually so that only the ones that are needed to be activated are activated. For example, if the sun shines on the downpipes on one side of the building the temperature may be above freezing temperatures, but on the other side of the building the temperature may be below freezing, then only the devices located on the side of the building that are in the shadow may be activated. Another example is that an operator can manually activate or deactivate certain devices in the system.

[0046] According to a third aspect there is provided a method for controlling the climate in a downpipe, comprising the steps of, providing a device according to any of the first aspect, to a section of a downpipe, providing a sensor for detecting the ambient conditions of the downpipe, detecting and comparing the detected ambient conditions with a predetermined set of values of the conditions, controlling the device to be in operation as long as the detected ambient condition remains equal to the predetermined set of values of conditions.

[0047] Providing the device at the lower section of the downpipe is advantageous as it facilitates the mounting of the device onto the downpipe. A further advantage of providing the device at the lower section of the downpipe is that the warm air travels though the main part of the downpipe and thereby comes in contact with the main part of the water, which leads to better prevention of ice formation. By providing a sensor that detects the ambient environmental conditions and comparing the detected ambient conditions with a predetermined set of values, the condition in the downpipe can be more precisely regulated, resulting in lower energy consumption.

[0048] Effects and features of the second and third aspects are to a large extent analogous to those described above in connection with the first aspect. Embodiments mentioned in relation to the first aspect are largely compatible with the second and third aspects.

[0049] According to an aspect there is provided a computer executable software, arranged to be executed on in a controller of device described above, the software executing a method comprising the steps of

[0050] -receiving environmental data from a sensor, and / or -receiving weather data from an external weather service. based on the received data, control the fan, and / or heater and / or an optional heating cable such that it or they are powered up for reducing ice build up and / or deicing purposes.

[0051] The advantages of the software is already described in relation to the first, second and third aspects above.

[0052] The present disclosure will become apparent from the detailed description given below. The detailed description and specific examples disclose preferred embodiments of the disclosure by way of illustration only. Those skilled in the art understand from guidance in the detailed description that changes and modifications may be made within the scope of the disclosure.

[0065] DETAILED DESCRIPTION

[0066] The present disclosure will now be described with reference to the accompanying drawings, in which preferred example embodiments of the disclosure are shown. The disclosure may, however, be embodied in other forms and should not be construed as limited to the herein disclosed embodiments. The disclosed embodiments are provided to fully convey the scope of the disclosure to the skilled person.

[0067] Figure 1 shows a cross-sectional view of the device 1 according to an example, being fully compatible with later on described second example of the device. The device 1 comprises a fan 7 for creating an airflow A in the downpipe 9, wherein the fan 7 is configured to be mounted at an opening 13 at the downpipe wall of the downpipe 9, wherein the opening 13 is arranged at a pipe section of the downpipe 9.

[0068] Depending on the diameter and length of the downpipe, varied sizes of the fan 7 may be considered. For example, the diameter of the downpipe 9 may be between 75mm and 150 mm, there could also be specific cross diameter pipes, such as 87 mm, or any other cross diameter. Further, depending on the diameter and length of the downpipe 9 and expected ambient temperature, varied sizes and / or power of the fan may be considered.

[0069] It should be understood that a downpipe is in general a metal pipe, however for the present disclosure downpipes of any sort may be arranged according to the disclosure. That is a downpipe in clay, concrete, wood or any other material may also be used with the present disclosure.

[0070] The fan 7 blows ambient air into the downpipe 9. The fan 7 may be an electric fan or any other suitable fan. The fan 7 is preferred to have the ability to move a predetermined volume of air each minute. The fan 7 is driven by a motor, which is as mentioned preferred to be an electric motor. The fan 7, preferably has a predetermined size that is in a range from half the internal diameter of the to two internal diameters of the internal diameter of the downpipe 9. A larger fan will in particular give a higher air flow without increasing the sound to the surroundings. Le. the larger fan need not have the same speed of the motor as a smaller fan for the same air flow. It should be said that when discussing the fan 7, it is meant both the fan per se and the motor powering the fan.

[0071] Figures 2 - 6 shows that the device 1 comprises a mounting element 2. The mounting element 2 is configured to be mounted at the opening 13 in the downpipe 9. The device 2 further comprises a cover element 4, preferably releasably attached to the mounting element 2. The cover element 4 is attached to the mounting element 2 with screws or other suitable connection mechanism. The cover element 4 may house the mounting element 2 and the fan 7 in order to protect them from the environment. The mounting element 2 features a 90- degree bend, forming an angular elbow section 25 that alters the orientation by 90 degrees relative to the adjacent straight sections of the mounting element 2. This elbow section 25 maintains preferably a consistent cross-sectional profile throughout the bend to ensure stability and alignment, minimizing stress and deformation. The bend radius of the elbow is designed to accommodate specific mounting requirements while ensuring structural integrity under operational conditions. The mounting element can also be a straight tube. The inner section 26 of the cover element may be adapted to the outer surface of the downpipe 9. In figure 2 the inner section 26 is disclosed as a having a radius adapted to the radius of the downpipe 9, with a squared downpipe 9 this section is preferred to be made flat.

[0072] To achieve a satisfying airflow A through the device 1, the cover element 4 is arranged with an air inlet 12. To prevent dirt from entering the device 1 and reduce the lifetime of the device 1, a protective mesh 15 may be arranged at the air inlet 12. The protective mesh 15 may be a metal net, a plastic net, or a sheet of metal or plastic with several holes arranged in the metal / plastic sheet. The protective mesh 15 may be arranged for easy removal, suitable for the maintenance of the mesh 15. The air inlet 12 may be directed downwards in order to minimize the risk of rain, snow or dirt entering the device.

[0073] To further facilitate the airflow A, the mounting element 2 is arranged with an air outlet 14. The air outlet 14 is fluidly connected to the fan 7 and fluidly connected to the opening 13 in the downpipe 9 for creating the airflow A in the downpipe 9. The air outlet 14 may comprise a protrusion 16 in the mounting element 2, the protrusion 16 may be coupled to the opening 13 in the downpipe 9. The protrusion 16 may be adapted to receive the fan 7. The protrusion 16 may protrude into the downpipe 7 by up to 20mm or more. The protrusion 16 may have a similar shape as the opening in the downpipe 9. For example, the protrusion 16 may have a circular cross section. In other words, the protrusion may have a ring shape. At the other end of the mounting element 2, adjacent to air outlet 14, the mounting element is arranged with an air inlet. The inlet may be directed at any angle suitable for the intended purpose. The fan 7 may be arranged at the inlet of the mounting element 2.

[0074] When device 1 is mounted at the downpipe 9, the protrusion 16 may be perpendicular to the downpipe 9. In other words, the center axis of the protrusion 16 may be perpendicular to a center axis of the downpipe 9.

[0075] Figures 2-6, further shows that the device 1 may be arranged with a heater 5. The heater may be arranged in fluid communication with the fan 7. The fan 7 and the heater 5 is in fluid connection with the air outlet 14, so that the fan 7 draws air from the outside of the cover element 4, heated air is blown thorough the air outlet 14 and into the opening 13 of the downpipe 9 and into the downpipe 9, resulting in an airflow A of heated air in the downpipe 9. The heater 5 may be arranged at the air inlet of the mounting element 2. It should be noted that the fan 7 and the heater 5 can be operated independently from each other. In other words, the fan 7 can be operated to blow air into the downpipe 9 that is not heated. On the other hand, the heater 5 can be activated without the fan 7 being activated. For example, can the heater 5 be activated to reduce the formation of moist in the cover element 4. The heat in the heater 5 is preferred to be produced by means of an electric element. The heater 5 may also be arranged as a combustion device, which allows for introducing a combustible material. This may be advantageous for temporary and quick use of the device 1 in temporary installations, where ice situation is particularly difficult. The heater 5 may be a PTC warmer. The heater 5 may be arranged to be water resistant.

[0076] The heater 5 and the fan 7 may for example be in the order of a total consumption of 300 W. If there is so desired this may be increased or lowered.

[0077] Figures 2 to 5 shows that the device 1 removably attached to the outside of the downpipe 9 with different types of fastening means 20. Any of the devices 1, described below may be combinations of each other. Thus, the device of Fig. 2 may be combined with any of the other devices according to Fig. 2, 3, 4, 5 but also 6.

[0078] Figure 2 shows that the device 1 is removably attached to the downpipe 9 with a screw clamp device. The screw clamp device is preferred to include two screws 20 of a standardized head, for example Torx, Philips, hexagonal, Allen screw. In figure 2 there is arranged an attachment section 23 that allows for the screws to be held before and during mounting of the device 1. The attachment section 23 outer section, is preferred to be angled 90 degrees to the left and to the right, protruding such that a screw 20 may be received in a boring of the attachment section 23. The screws protrude to a respective holding device 24, that act as a counter hold for the device and being essentially on the opposite side of the device 1 itself. The holding device 24 is preferred to have a thread for each screw 20, such that it is not needed to add a nut when mounting the device 1.

[0079] Figure 3 shows that the device 1 is removably attached to the downpipe 9 with magnets 20a. The magnets in this case may be a long vertically extending magnet plate. The magnets may also be round smaller magnets. The magnets may be incorporated into any part of any variant of the device 1 that is in contact with the downpipe. In the Fig. 2 variant the element 29, the attachment section, may be magnetic itself. The magnet option is fully compatible whit any other variant discussed. For example, the Fig. 1, 2, 4, 5, 6 variants may also have a magnetic attachment section. This is particularly advantageous as the device may be temporarily attached and then finally fixated with a further device according to Fig 1. - Fig. 6. It should be understood that if the downpipe is made in a material that is not magnetic, a magnetic element may be applied for example on the inside or the outside of the downpipe 9 for the magnets to attach to. If desired the element may be a magnet itself, in particular if a particularly strong magnetic bond is desired.

[0080] Fig. 3 may alternatively use holes 28 in the attachment section, i.e. element 29, for attachment with screws and / or pop rivets, or rivets in general, this also combinable with magnets or not.

[0081] The attachment section, i.e. element 29, of Fig. 3, may be provided with a relatively soft material, that may shape itself after the outer contour of the down pipe. The soft material may be a soft metal, that is with an appropriate thickness for being shapeable, for example in steel, or aluminium, or any other suitable material. This is also relevant for Fig. 2 where there may be a soft material in the intermediate section between the screws 20 and the body itself of the device 1. In this case the outer section of the attachment section 23, should be harder for the screws 20 to be able to function properly. The same relevant for Fig. 4 variant, hard attachment section 23c, but soft material leading up to the device in intermediate section.

[0082] The attachment section 29 in Fig. 3, may also be provided with hinges 30, 31, that provides for a hinging functionality to the attachment section 29 (element 29). The hinging functionality may increase adaptability when attaching to a flat surface, for example a squared down pipe, that is a down pipe with a squared cross section. Figure 4 shows that the device 1 is removably attached to the downpipe 9 with rubber attachments 20c. The rubber attachments 20c disclosed in Figure 4 has a certain elasticity. This elasticity is predetermined in such a way that the elasticity is also present at temperatures well below the freezing point. The attachment section 23c is preferred to be arranged with hook elements 1 that holes in the rubber attachments 20c may engage. There may be hook elements on the other side of the device 1 in corresponding attachment section 23 c (not disclosed). In an alternative variant the rubber attachments are exchanged or combined with to hook and loop fasteners (not shown). There is also a variant to use cable tie attachments, in the same way. In this case the removal of the device, may require a knife or a sharp object.

[0083] Figure 5 shows that the device 1 is removably attached to the downpipe 9 with hose clamps 20d. The house clamps 20d may be introduced in a slot in the attachment section 23, or they may be fixedly attached to the attachment section 23, such that the clamps will not be lost from production to the mounting site.

[0084] It should be noted that the device 1 can be attached to the downpipe 9 with any suitable means such as rivets or screws, but also tape, adhesive, or the like, in any combination and also combinable with all attachment variants as mentioned.

[0085] Figure 6 shows that the device 1 is permanently attached to the downpipe 9 by welding. Any suitable welding may be used. This may be a solution where the device 1 is prone to be demounted by unauthorised persons or otherwise similar situations. This variant is also possible to combine with for example glue, adhesive, magnets, for temporary attachment while the welding is done at site of installation.

[0086] Not shown if Fig. 2 or any of figures 3, 4, 5 and 6, the attachment section 23 is preferred to be two, one on the left side of the device 1 and one on the right side of the device 1. It is of course thinkable of having only one attachment section for example to the left side, and having a longer element, adapted to the outer contour of the down pipe, and running around the down pipe 9 to for example a hinged attachment on the right side. Thus, a "clamp" around the down pipe is achieved, with an attachment on one side (left) of the down pipe. This design may be reversed of course in left / right direction.

[0087] The hinging functionality may also be applied to any of the other variants. For example, in Fig.

[0088] 2 the attachment section 23 may be hinged for adaptation to different measures of down pipes, e.g. different diameters. The same is applicable for Fig. 4 variant, where a hinge helps to get the hook elements 1 in correct position before strapping to the down pipe.

[0089] The upper 32 attachment section may be applied to any variant of Figures 2-7. This may have the properties of the attachment sections 29 of the sides as described above, i.e. soft material, and / or hinges, magnets, adhesive, screws, pop rivets etc.

[0090] The lower 33 attachment section variant of Figures 2-7. This. This may have the properties of the attachment sections 29 of the sides as described above, e.g. soft material, and / or hinges, magnets adhesive, screws, pop rivets etc.

[0091] Figure 2 further shows that the device 1, regardless of attachment method thus relevant for any of Fig. 2-7, may further comprise a sensor 17 for measuring climate data, i.e. environmental data, a controller 19 arranged to receive the climate data from the sensor 17 and to control the device 1 based on the climate data. The climate data may be for example temperature and / or air humidity and / or air pressure. The controller 19 receives the climate data and determines if the fan 7 and / or the heater 5 should be activated or deactivated. Thus, the total time the device 1 is active may be shortened, as compared with a device that is always on. For example, if the sensor 17 detect that the temperature drops below 0°C, the controller 19 sends power to the fan 7 and / or the heater 5, resulting in ambient air or heated air is blown in to the downpipe 9, thereby preventing ice from forming in the downpipe 7. When the temperature rises above 0°C, the controller 19 deactivate the power to the fan 7 and / or the heater 5. The sensor 17 and / or the controller 19 may be arranged at the inside of the cover element 4. The sensor may also be arranged at the mounting element 2 and housed by the cover element 4. The sensor 17 and / or the controller 19 may also be arranged on the outside of the cover element 4. The controller 19 may be arranged to also set the power of the fan 7 and / or the heater to different levels, such as low power, middle power and full power. In this way the control may be changed according to sensor input, in particular difficult icing situations depending on temperature, air humidity, and air pressure may be detected and the power may then be adjusted.

[0092] It is preferred that the sensor 17 is positioned away from downpipe 9, such that heating of pipe does not affect sensor detection. This is most relevant if the sensor 17 detects temperature, which is the most relevant parameter for the device 1, 1'.

[0093] The device 1 may be arranged for automatic control of heating by means of the controller 19, as said above. The controller 19 may be set for a range, for example temperature range, for powering up the fan 7, or powering up both the fan 7 and the heater 5. The range for powering up the fan 7 and / or the heater may be set at a standard range of 0°C to - 8°C. The determination of the current ambient air temperature may preferably be made by using the sensor 17. The temperature range may be manually adjusted. As an example, if it is observed locally that there is a need of heating particularly between -1°C and -4°C, the range may be manually set to these values.

[0094] The controller 19 is arranged to receive sensor data and then act up on the sensor data as stated above. As for example sensor 17, the controller 19 is arranged to determine if the fan 7 and heater 5 is to be powered up or powered down. The determination may be calibrated by an operator, observing the build up of ice, and adjusting the temperature range depending on the environment. Then, the observed calibration data may be uploaded to individual devices 1.

[0095] The device 1 may further comprise a local communication device 21 for remote control of the device 1. The local communication device 21 may be a radio Frequency (RF) Transmitters and Receivers, Infrared (IR) Controller, Bluetooth Module, Cellular Module or WiFi Module. The communication may also be made by wired communication.

[0096] The controller 19 of the device 1 may thus through the communication device 21 be arranged to receive weather data from an external weather forecasting service. This, may be used for proactively by the controller 19 to start up fan 7, heater 5, and / or optional heating cable 40, before precipitation arrives. The controller 19 may also receive direct real time weather data, i.e. not forecasted date but measured data. Based on these data the control of the device 1 may be arranged for preventing ice build-up and / or de-icing purposes. Thus, the device 1 may using the communication device 21 optionally not include a sensor device 17, and instead get control from external sources.

[0097] To power the device 1, the device 1 may comprise an electric grid interface, preferably in the form of an electric cable 37, Fig. 7a. The device 1 may also be powered by batteries that are charged by the electric grid or by solar panels.

[0098] The device 1, may have a dual capability. With dual capability is meant that the device 1 may use the fan 7 and heater 5, Fig. 1, as means for heating. The fan 7 and heater 5, may in addition be helped by an arrangement of the device 1 such that it may power and / or control a heating cable 40 too. This is particularly advantageous if the device 1 is mounted at a distance from the lower opening 41 of the down pipe 9. In some situations, there may be ice forming at the opening and up to the point where the device 1 is using the fan 7, and heater 5, for the remaining length of the down pipe 7. A typical length of the heating cable 40 may in this case be 2 - 3 meters, for example 2,5 meters. It is preferred that the controller 19 is arranged such that it may determine if to power the fan 7 and or the fan 7 and the heater 5 for heating and combine this with also controlling and powering up the heating cable 40. The controller 19 may as with the fan 7 and the heater 5 use input data, for example from sensor 17, to determine that the heating cable 40 should be powered up for heating. The controller 19 may also be arranged such that it determines that both the heating cable and the fan 7 with heater 5 is powered up, i.e. turned on. Thus, the cable 40 may be determined to be used individually, alone, together with the fan 7, and / or together with the fan 7 and the heater 5. The range for determining this may be as mentioned above, such as 0°C to - 8°C, or -1°C to -4°C. There may also be two different range of detected temperatures for the heating cable and the fan 7 or the fan with heater 5 for powering up and down.

[0099] The device 1 and the device 1' are arranged such that it may have a heating cable 40 installed at need. In Fig. 7a such a heating cable 40 is exemplified. In Fig. 9 the prepared installation feature 39 for the heating cable is shown. The circuitry and control functionality of the device 1 or 1' are preferably already in place, such that easy modification to dual use o heating cable 40 is achievable.

[0100] At open down pipes 9 the need for a heating cable is higher, as ice may form close to the opening 41 below the device 1. 2- 2,5 meters from the mounting height of the device 1.

[0101] The device comprises a circuit board with controller 19 may have buttons and / or turn controls for setting temperature ranges.

[0102] Fig. 9 shows a second variant 1' of the device 1. The two devices 1, 1' have the same functionality and only structural differences is relevant. Thus, all said about the first example of the device 1, is relevant for the second variant of the device 1'. In particular the devices attachment methods are completely the same. In Fig. 10 the device 1' has inside the outlet pipe 2 of air a small step wall 35 that prevents water to go backwards up to the fan, if for example heavy rain fills the down pipe 9. This step wall 35 is also applicable to the first device 1. The device 1' has a moved circuit board 43 with control unit 19 arranged at the lower part of the device 1'. Lower part essentially should be construed under the level of the fan. Thus, the circuit board 43 may be arranged higher up in the device 1'. The arrangement of the circuit board 19 improves the durability and resistance to any water coming from above. The device 1' also need no internal wiring from the bottom up to the circuit board 43 arranged in the top of device 1. The device 1' is seen in a section view in Fig. 10. The functionality of the two devices 1, 1' is the same. The fan 7, heater 5, and provision of possibility to attach an optional heater cable 40 is the same for both devices 1, 1'.

[0103] The mounting element 2 of both devices, may be supplemented with a further mounting arrangement 44 above or below the mounting element 2, Fig. 10. The supplemental mounting arrangement 44 may be arranged as a recess into the device 1, 1' at the side facing the down pipe 9.

[0104] Fig. 10 shows two down pipes 9 and 9'. This is only drawn to show that the device 1, 1' may be mounted on down pipes 9, 9' with different diameters, as well as squared down pipes, or basically any shape of the down pipe is possible to mount the device on.

[0105] The device 1, 1', Fig. 10 may be provided with indication lights 45. There may be one light 45, or for example two lights. The indication light may indicate that there is electric power provided to the device, for example indicated by a red light. The same indication light or a further light may indicate that the device is operating, for example by a green light.

[0106] Figure 7 shows a system 100 for climate control in a house water drainage system. The system comprising at least one downpipe 9, wherein a device 1 is mounted at the at least one downpipe 9. All the features of the system 100 are interchangeable and fully compatible with device 1 and / or device 1'.

[0107] In fig. 7 of the system, it is also shown how to mount the device 1. On the left side a single device 1 is mounted. The mounting is preferred to be around 2 meters or more over the ground level for the safety reasons. On the right side there is disclosed two devices 1, one lower and one higher. This is particularly advantageous if the system 100 requires more airflow and / or heating, for example on the shadow side of a building where more ice is prone to form. The same electric input may be used for both devices if they are coupled in series as in Fig. 7. This is also true if an optional heater cable is attached to the device 1.

[0108] It should be understood that for any of the devices and the system of two or more devices on the same pipe, there is only one electric input cable needed for both fan / heater / cable. Thus, a power cable 37 installation is simplified as there is only need for external input of power to a first device. Then an intermediate power cable 42 may be run from the first device 1, l'to the second device 1, 1' etc, Fig. 7a. It should be understood that the devices in the system may have different power ratings. For example, a lower device may have a power of 450 W reaching for example 10-15 meters upwards of a down pipe for heating purposes. A 300 W device may reach 6 to 10 meters, and a 200 W device may reach 1 to 6 meters. A device higher up may be sufficiently powered by for example 200 W

[0109] The system 100 may further comprise a communication device 22 for communication between the system 100 and each device 1 in the system 100, for remote control of each device 1. The devices 1 in the system 100 may be controlled individually or simultaneously depending on what is most energy efficient. The communication device 22 may be a radio Frequency (RF) Transmitters and Receivers, Infrared (IR) Controller, Bluetooth Module, Cellular Module or Wi-Fi Module. The communication may also be made by wired communication. As said before this is also relevant for the second variant 1' of the device.

[0110] The communication device 22 may also be arranged such that when one device 1 of a group of devices 1 is powered a signal data is automatically sent by the central communication device 22 to each device 1. As said before this is also relevant for the second variant 1' of the device.

[0111] The system 100 may also involve a downloadable software to a mobile telephone, an so called app, i.e. a downloadable user interface on a mobile device. The app may be arranged for controlling the device 1 and / or a group of devices 1. For example, the app may be used for setting temperature ranges for the on and off, i.e. powering up and down of the fan 7 and / or heater 5 and / or heating sling. The app may have the functionality so that it will receive weather data. This data may be used for alerting or notifying a user, on weather that may initiate ice build up on roofs and down pipes etc. The app may in particular be arranged such that weather data received by the app, for example from general weather services. This will as an example lead to the for example, snow predicted to fall is notified to controllers 19, devices 1,1'etc. Thus, fans 7, heaters 5 and / or heating cables 40 may be powered up in advance. This, may be beneficial as it is more energy effective to prevent ice building up than removing already formed ice. The app may also control the device 1,1' such that if there is snow in the weather forecast it will start up the fan 7, and / or heater 5, and / or an optional heater cable 40 when it is determined that snow is inbound. The app may be arranged such that a user can monitor the operation of the devices 1. This monitoring includes indication that the device 1 or group of devices 1 is / are operating or shut off. The app may also have the possibility to be used for manually switching devices 1, on and off. The operation of the app uses the local communication device 21 for of the devices as a communication means.

[0112] The app may be arranged to issue warnings to the app, such that a logged on user, may see that fore example devices 1, 1' have start operating in any mode. This allows for example the user to turn of the device 1, 1', should the user deem that the device 1, 1' does not need to be operating currently.

[0113] There is also possible that a controller 19 in one device 1 of the system 100, determines to power up the particular device 1 in a group of devices, and then the controller 19 is arranged to communicate this powering up to other devices 1, and / or to the communication device 22, over the local communication device 21 to the group of devices 1 such that all devices 1 may receive the information that one device has now been powered up. Then there may be so that the controller 19 of each device may decide, to power up, or not based on the received data.

[0114] There may also be a manual control of the devices 1 such that a human operator determining that there is need for one or more devices 1 to be powered up, the device 1 or devices 1 may be powered up. The reverse is also possible, i.e. the communication device 21 may be used for powering down the device or devices.

[0115] Figure 8 shows a flowchart of a method according to an example. The method relates to a method for controlling the climate in a downpipe. The method comprising the steps of: providing S101 a device 1 according to any of the first aspect, to the lower section of a downpipe 9, providing S102 a sensor 17 for detecting the ambient conditions of the downpipe 9, detecting S103 and comparing the detected ambient conditions with a predetermined set of values of the conditions, controlling S104 the device 1 to operate as long as the detected ambient condition remains equal to the predetermined set of values of conditions. That is, if a predetermined condition is fulfilled, the device 1 is controlled to be powered on. If different predetermined condition is fulfilled, the device 1 is controlled to be powered off. It is also possible to add more power to the fan 7 and or the provided heater 5, if the conditions so require.

[0116] There is also involved a computer executable software, arranged to be executed on in the controller 19 of a device 1, 1, the software executing a method comprising the steps of

[0117] -receiving environmental data from a sensor 17, and / or -receiving weather data from an external weather service. based on the received data, control the fan 7, and / or heater 5 and / or an optional heating cable 40 such that it or they are powered up for reducing ice build up and / or deicing purposes.
