Definitions

  • the present invention relates in a first aspect to a method for controlling and regulating the power supply of a Peltier element of a cooling box according to the preamble of claim 1.
  • the invention in a second aspect, relates to a control and regulating device for the power supply of a Peltier element of a cooling box according to the preamble of claim 8.
  • an interior of the cooler with the Peltier element is at least temporarily cooled. It is applied to supply energy of the Peltier element an AC voltage to an electrical input of the cooler, the AC voltage is converted into a DC voltage and the Peltier element is supplied with the DC voltage.
  • an internal temperature in the interior of the cool box is determined.
  • Methods are also known in which a DC voltage is applied to an electrical input of the cooling box for supplying energy to the Peltier element.
  • the applied DC voltage can be converted, for example, by means of a transformer to a desired amount of voltage.
  • a generic control and regulating device for the power supply of a Peltier element of a cooler has an electrical input to which an AC voltage can be applied.
  • a first connection for connection to an internal temperature sensor of the cooling box and an evaluation unit for determining an internal temperature by means of the internal temperature sensor are provided.
  • Other generic control and regulating devices are designed for connecting DC voltages. These DC voltages can then be converted, for example, by means of a transformer to a desired amount of voltage.
  • control and regulating devices are known which have additional means for determining the applied voltage and influence the further transformation of the applied voltage on the basis of the decision of this additional means.
  • Such a method and such a control and regulating device are made DE 295 03 576 U1 known.
  • a temperature sensor and a control and regulating device are provided in a cool box to maintain an approximately constant temperature inside the cooler.
  • JP 2007-139328 A a cooling container with an internal thermometer, a Peltier element and a control device is known.
  • the control device switches off a cooling process when the internal temperature drops below a predefinable minimum temperature.
  • the Peltier element is operated in two operating modes, namely on the one hand supplied with a certain energy and on the other hand switched off.
  • the disadvantage here is the one caused by the frequent switching operations energy consumption.
  • a temperature equalization quickly takes place between the heated side and the cool side of the Peltier element Peltier element instead. This also increases the energy required to maintain a low temperature in the interior of the cooler.
  • Compressor refrigerators which regulate their cooling capacity depending on the internal temperature in the refrigerator, are in DE 601 29 231 T2 .
  • a disadvantage of known control and regulating devices as well as known methods is that to achieve a predetermined temperature in a cool box unnecessarily much energy for the energy supply of the cool box is applied.
  • an object of the invention can be considered to provide a method which cools the interior of a cooler as energy efficient as possible with a Peltier element.
  • a control and regulating device is to be created, which keeps the energy consumption of a Peltier element of a cool box as low as possible.
  • an ambient temperature outside of the cool box is determined and depending on the determined internal temperature and the determined ambient temperature, the energy supply of the Peltier element is adjusted.
  • the adjustment of the power can be done in different ways.
  • the current intensity or the voltage can be varied.
  • the DC voltage supplied to the Peltier element can also be a pulsed DC voltage or a varying DC voltage. In this case, the frequency or the maximum amplitude of the changed DC voltage can also be varied.
  • an icebox within the scope of the invention may also be considered an insulated casing with one or more compartments intended for refrigeration or freezing of food or storage of chilled or frozen food for non-commercial purposes and cooled by one or more energy consuming processes including equipment sold as kits for assembly by the user.
  • this reduces the total energy or power required for sufficient cooling of the interior.
  • the required cooling capacity is dependent on the difference between the ambient temperature, that is the temperature outside the cool box, and a temperature to be reached in the interior of the cool box. With knowledge of the ambient temperature, the energy taken from the external power supply and accordingly also converted energy can be so dimensioned that it is sufficient to reach a given internal temperature, but does not exceed the predetermined internal temperature.
  • the energy taken and converted from the external power supply would have to be at a level at which the extracted and converted energy is sufficient to maintain the interior of the cooler box at the highest allowable outside temperature using the Peltier element means highest possible operating temperature, sufficient to cool.
  • the maximum necessary energy would still be converted without regulation based on the ambient temperature.
  • this is not necessary for cooling, so that either the interior of the cooler is cooled more than necessary, or converted too much Energy disposed of in any way or consumed, for example, must be dissipated via a resistor.
  • the power taken from an external power supply and thus converted can be reduced if the ambient temperature is lower than the maximum permissible ambient temperature for which the cooling box can still reach a predetermined internal temperature.
  • This may be a predetermined period of time to achieve the desired internal temperature to be considered, since it depends on the desired temperature in the interior of the cooler, on the cooling performance of the Peltier element, how fast a predetermined internal temperature can be achieved.
  • it can also be realized that at the beginning of the cooling phase the maximum possible energy is rectified or converted and thus rapid cooling of the interior can take place. If the interior is at the desired temperature, the converted energy or power can be adjusted, so that only as much energy is converted as is necessary for maintaining the desired temperature within the cooler.
  • the energy efficiency of the cooling of the cooler is improved.
  • the converted energy can be reduced to such an extent that the active cooling substantially compensates losses of the cooling box. In addition, this ensures that a predetermined internal temperature is not exceeded.
  • the amount of the DC voltage is adjusted depending on the ambient temperature and / or the internal temperature and / or the current intensity of the power supply of the Peltier element can be adjusted depending on the internal temperature and / or the outside temperature.
  • this not only reduces the power applied to cooling power, but also the total energy consumption of the cooler, which in addition to the applied cooling power dissipation in the conversion of AC voltage to DC voltage and other power losses must be considered.
  • the adaptation of the power supply of the Peltier element in particular the amount of the DC voltage and / or the current intensity, are performed as a continuous function of the ambient temperature and / or the internal temperature.
  • a continuous function can be understood as meaning both a strictly mathematically continuous function and a function which has a constant or only very slight change in pitch.
  • the adaptation of the energy supply of the Peltier element can not be achieved simply by a simple function On and off the power supply of the Peltier element can be realized. If the power supply of the Peltier element is not adjusted by switching the power supply on and off and the energy supply is adjusted in terms of its performance, the energy expenditure generated during switching operations is avoided and the energy efficiency thereby increased.
  • a continuous function may be an at least partially linear or approximately linear function.
  • the function can be linear in an interval of the ambient temperature, for example from 16 ° C. to 32 ° C., in particular run with a substantially constant gradient, and approach a specific value for lower ambient temperatures. As the ambient temperature decreases, the converted energy is linearly reduced to a minimum limit.
  • the energy supply of the Peltier element does not fall below a predefinable minimum energy supply, in particular the amount of the DC voltage does not fall below a predeterminable minimum voltage and / or the current intensity of the energy supply does not fall below a predeterminable minimum current intensity. Additionally or alternatively, it can also be provided that the energy supply of the Peltier element does not exceed a predefinable maximum energy supply. In this case, in particular, the amount of the DC voltage can not exceed a predefinable maximum voltage and / or the current intensity can not exceed a predefinable maximum current intensity. This ensures that the cooling box for cooling does not exceed a defined maximum energy consumption.
  • the current intensity of the energy supply of the Peltier element is reduced to the extent that no or substantially no further temperature reduction takes place in the interior. This ensures that the interior is not cooled further. This is particularly relevant because there are guidelines on how cold interior spaces of coolers may be cooled to comply with certain legal requirements.
  • Peltier element If a Peltier element is supplied with energy, in particular electricity, then one side of the Peltier element is cooled, whereas the thermal energy is shifted to the other side. This page is therefore warmed up.
  • the Peltier element can therefore generally be referred to as a heat pump.
  • the cooling performance or energy efficiency depends on the differences between the hot and cold side. The lower these are, the more energy-efficient the cooling can be carried out by means of a Peltier element. Therefore, on the warm side of the Peltier element often a device for surface enlargement, such as cooling fins, attached. These serve to better release the heat energy to the environment.
  • an air flow is generated with a fan on the warm side of the Peltier element, which serves to better dissipate the thermal energy.
  • cooled air can be distributed by the Peltier element with a second fan in the interior of the cool box.
  • the energy supply of the fan is preferably dependent on the determined internal temperature and / or the determined ambient temperature adjusted.
  • the energy available to the fan is not constant, but may be increased when more cooling is needed on the warm side of the Peltier element, or if more agitation is desired within the cooler. Cooling the Peltier element only with a low power, so the fan can be supplied with less energy. This increases energy efficiency.
  • a fan If a fan is supplied with less energy, it turns at a lower frequency, which means that the actual fan wheel rotates at less revolutions per minute. This changes the amount of air circulated by the fan per unit of time. It is also possible to use a fan each for discharging heated air on the outside and for distributing cooled air in the interior space.
  • a second connection is provided for connection to an ambient temperature sensor of the cooling box.
  • the evaluation unit for determining an ambient temperature by means of the ambient temperature sensor is set up and there are means for adjusting the power supply of the Peltier element depending on the determined internal temperature and the determined ambient temperature available.
  • this adjusts the energy taken from an external energy source to the energy required for cooling.
  • the energy actually required is absorbed and consumed.
  • the power supply in particular a rectification of an externally applied AC voltage, can be adapted such that not too much or too much energy is provided and converted in order to reach a certain internal temperature.
  • the means for adjusting the power supply comprise means for adjusting the amount of DC voltage depending on the determined ambient temperature and / or the determined internal temperature.
  • the means for adjusting the power supply may comprise means for adjusting the current intensity of the power supply of the Peltier element depending on the determined outside temperature and / or the determined inside temperature.
  • the means for adjusting the power supply are adapted to adjust the power supply of the Peltier element, in particular the amount of DC voltage and / or the current, as a continuous function of the ambient temperature and / or the internal temperature.
  • the means for adjusting the energy supply can be set up, in particular, to carry out the adaptation via an at least partially linear function. Compared to sudden changes in the adaptation, as they would for example be present if the power supply is temporarily completely interrupted, can be set for any indoor and / or ambient temperature, a specific power supply. But it is also possible to adjust the energy supply gradually. For example, it is conceivable to adjust the magnitude of the rectified voltage gradually, depending on the outside temperature.
  • Another embodiment of the invention provides that the means for adjusting the power supply are set up so that the energy supply of the Peltier element does not fall below a predefinable minimum energy supply, in particular that the amount of DC voltage a predetermined minimum voltage and / or the current does not have a predetermined minimum current below.
  • a temperature difference is maintained between the warm and the cool side of the Peltier element. This prevents that between the warm and the cool side of the Peltier element, a temperature compensation takes place, which would be accomplished if the Peltier element is no longer with energy is supplied.
  • the overall energy requirement is reduced because no unwanted heating of the interior of the cooler by the temperature compensation of the Peltier element takes place.
  • the means for adjusting the power supply can be set up so that the energy supply of the Peltier element does not exceed a predefinable maximum energy supply, in particular that the amount of the DC voltage does not exceed a predefinable maximum voltage and / or the current strength does not exceed a predefinable maximum current intensity.
  • the means for adjusting the power supply are arranged so that when the determined internal temperature has reached a predeterminable minimum temperature, the energy supply of the Peltier element, in particular the current intensity of the power supply of the Peltier element, is so far reduced in that no or substantially no further temperature reduction takes place in the interior. It is thus prevented that a cooling that is stronger than necessary, is performed and thereby increases the energy consumption.
  • the minimum temperature can be set via buttons or a control wheel, preferably with a display for displaying the set minimum temperature. Likewise, keys or a control wheel for setting a maximum temperature, which should always be below in the interior, be provided.
  • an electric fan outlet for connecting at least one fan for discharging heated air to an outside of the cooler and / or for distributing cooled air in the interior of the cooler is provided, and the means for adjusting the power supply are adapted to Adjust the power supply of the fan depending on the determined internal temperature and / or the determined ambient temperature. This allows the fan to rotate at a higher rotational frequency when the power supply is increased.
  • a control and regulating device can be used together with a cooling box.
  • This cooler should then additionally have an interior for receiving objects and a Peltier element for cooling the interior.
  • the cool box may include an indoor temperature sensor and an ambient temperature sensor.
  • the Peltier element, the inside temperature sensor and the ambient temperature sensor are connected to the control device.
  • Such a cool box is characterized by its particularly energy-efficient operation.
  • a fan for removing heated air may be arranged on an outer side of the cooling box and / or for distributing cooled air in the interior. It can also be provided depending on a fan for the above functions.
  • a control and regulating device can only adapt the energy supply of the Peltier element depending on a determined internal temperature.
  • an AC voltage of an external power source is converted into a DC voltage whose amount depends on the detected internal temperature.
  • the DC voltage is adjusted to a fixed value of, for example, approximately 12.5 volts. If the specified target internal temperature is reached, the AC voltage is adjusted to a lower DC voltage, thereby reducing energy consumption.
  • the adaptation of the DC voltage can be effected as a function of the temperature difference by which the desired internal temperature is undershot from the actual internal temperature.
  • the DC voltage should always be greater than a predefinable minimum voltage, for example greater than 6.5 volts. If necessary, a fan can be supplied with energy in addition to the Peltier element with the DC voltage.
  • Fig. 1 shows a control and regulating device 10 according to the invention for the power supply of a Peltier element 6 of a cool box. Also shown are an AC voltage 7 supplied to an electrical input of the control and regulation device 10 from an external power supply, as well as an ambient temperature sensor 3, an internal temperature sensor 4 and a fan 5 attached to the cooling box.
