Summary of the invention
In addition, the present invention aims to provide the energy consumption upper limit, and this energy consumption upper limit is relevant at interval with the specified temp that is used for internal temperature.
As seen, purpose of the present invention has shown a kind of method, and this method is come the inner space of cooling refrigeration case by the effective as far as possible energy of peltier-element utilization.In addition, make control and adjusting device, low as far as possible with the energy demand of the peltier-element that keeps cooler bin.
The control and the adjusting device of the method for the feature by having claim 1 and the feature by having claim 8 realize this purpose.
With the preferred embodiment of method preferred embodiment of the present invention and control of the present invention and adjusting device theme as dependent claims, especially, in conjunction with the accompanying drawings, the preferred embodiment of method of the present invention and the preferred embodiment of control of the present invention and adjusting device have also been described in the following description.
In the method for the invention, determine environment temperature, and supply with according to the energy of determined internal temperature and determined environment temperature adjustment peltier-element in the cooler bin outside.
According to the intent of the present invention, be appreciated that the energy supply of adjusting peltier-element, wherein, change from external energy and supply with the energy that is obtained.Therefore, not only can change the power that offers peltier-element, and can change supply with to receive (take up) by external energy and conversion be used for the power of peltier-element.Thereby, can take place power is adjusted into dissimilar power.For example, can change current strength or voltage.According to employed peltier-element, the dc voltage that offers peltier-element can also be pulsed D C voltage or variable dc voltage.In this case, can also change the frequency or the amplitude peak of the dc voltage of being adjusted.
Heat insulation shell (insulated housing) with one or more compartments can also be considered as cooler bin within the scope of the invention, this housing be for cool off or frozen food or storage be used for the non-commercial purpose cooled off or freezing food and cool off this housing by one or more energy consumption methods, comprise the device of selling as the completed knocked down products of making by the user.
Thereby, advantageously reduced and be used for needed gross energy in abundant cooled interior space or power.Necessary cooling power depend on environment temperature (that is, the temperature of cooler bin outside and will inner space at cooler bin in the temperature that reaches) between deviation.By the understanding environment temperature, can still not measure obtained and energy that therefore change to be enough to reaching predetermined internal temperature from the external energy supply above the mode of predetermined internal temperature.
On the other hand, when not understanding environment temperature, supply with the energy that is obtained and change from external energy and will have to reach a kind of like this level, promptly, the energy with being changed that is obtained is enough to the inner space that the booster action by peltier-element fully cools off this cooler bin with the highest tolerable external temperature (that is the highest tolerable running temperature).Under the situation of the environment temperature that is lower than the maximum admissible environment temperature, still change maximum necessary energy and do not regulate based on environment temperature.Yet, there is no need to cool off, thereby make than the inner space of cooling off this cooler bin more that needs, perhaps the too high amount of energy of being changed is handled or consumed to (for example, by resistor consumption) in some way.
By determining environment temperature, therefore, when environment temperature is lower than maximum admissible temperature, can reduces from external energy and supply with the power that is obtained and therefore change, wherein, cooler bin still can reach predetermined internal temperature.Thereby, the predetermined time cycle of the internal temperature that may need to consider to be used to reach desired was because should the time cycle depend on the cooling power that can how soon reach the peltier-element of predetermined internal temperature according to the desired temperature in cooler bin inside.With regard to this respect, also may realize, when cooling stage begins, therefore rectification and conversion maximum possible energy and may produce the quick cooling of inner space.If the inner space is desired temperature, then can adjusts energy or the power of being changed, thereby make that only conversion maintains the energy that the desired temperature in the cooler bin need be changed.
By understanding internal temperature, can avoid unnecessary cooling.Therefore, advantageously, improved the energy efficiency of cooling off this cooler bin.When arriving predetermined internal temperature, the energy of being changed can be reduced to the degree that initiatively cooling compensates the loss of cooler bin basically.In addition, guaranteeing that this temperature does not drop to is lower than predetermined internal temperature.
In the preferred variant of the inventive method, adjust the dc voltage value and/or can adjust the current strength that the energy of peltier-element is supplied with according to internal temperature and/or external temperature according to environment temperature and/or internal temperature.Advantageously, thereby not only reduce the power that cooling is consumed, and reduced the total power consumption of cooler bin, thereby, except the power that cooling is consumed, consider with the AC voltage transitions to be power consumption and other power consumptions of dc voltage.
In theory, can also adjust the dc voltage value and adjust the current strength that the energy of peltier-element is supplied with according to internal temperature according to external temperature.
In another embodiment, adjust the energy of peltier-element and supply with, especially dc voltage value and/or current strength are implemented as the constant function of environment temperature and/or internal temperature.According to the solution of the present invention, constant function can be interpreted as the constant function on the strict mathematical meaning and have constant or the function of the growth pattern of very faint change only.Particularly, not that the simple connection of only supplying with by energy and disconnecting realizes that the energy of adjusting peltier-element supplies with.If do not have to implement the connection of supplying with by energy and disconnect the energy of adjusting peltier-element to supply with and adjust respectively the energy of its power and supply with, the energy consumption that then can avoid during handoff procedure being generated and therefore improved energy efficiency.
Owing to usually between the cold side of peltier-element and hot side, have high-termal conductivity, advantageously, may supply with as constant function and guarantee that the cold side of peltier-element heats by hot side by adjusting energy.This is the situation of the energy supply disconnection of peltier-element.Then, peltier-element is tending towards being implemented in the temperature-compensating between cold side and the hot side, thereby heating is arranged in the cold side of inner space.Thereby unfriendly, also heat the inner space.Constant function can be partial linear or virtual linear function at least.Thereby this function can be linear the interval of environment temperature (for example, from 16 ℃ to 32 ℃), and especially, being constant basically increases operation and the approaching more particular value of low ambient temperature that is used for.Under the situation that reduces environment temperature, therefore, the energy that linear minimizing is changed is till minimum threshold.
In a preferred embodiment, the energy of peltier-element is supplied with not to be reduced to and is less than predetermined least energy supply.Particularly, the dc voltage value is not reduced to the current strength of supplying with less than predetermined minimum voltage and/or energy and is not reduced to less than predetermined minimal current intensity.Additionally or alternatively, also may provide the energy of peltier-element to supply with to surpass predetermined ceiling capacity and supply with.Particularly, thus the dc voltage value can not surpass predetermined maximum voltage and/or current strength can not surpass predetermined maximum current intensity.Thereby, guarantee that refrigeration case does not surpass the maximum energy consumption that is used to freeze that is limited.
