Definitions
- the invention relates to a method for preparing a transport container, can be transported with the temperature-sensitive cargo at a lying in a predetermined target temperature range temperature.
- the invention relates to a method having the features of the preamble of claim 1.
- Transport containers of the type in question are used for special transport purposes, in which the item to be transported during transport must necessarily be kept in a specific temperature range, the nominal temperature range.
- Such requirements for transport containers apply, for example, to the transport of temperature-sensitive goods such as pharmaceuticals, biotechnological products, transplanted goods or stored blood.
- the optimum transport and storage temperature to be observed is 2 ° C to 8 ° C.
- the products are only stable in a narrow temperature range. These products must therefore be transported and stored in this temperature range.
- such products that are very sensitive to the transport temperature must never freeze under any circumstances. Temperatures below 0 ° C must then be safely avoided. It is therefore about a safe achievement and compliance with the target temperature with a relatively small deviation.
- the area in which the target temperature is located is referred to herein as the target temperature range.
- the target period in the desired temperature range, are located during the transport of cargo in the receiving space latent heat storage elements that have been conditioned to a certain temperature, the target temperature are. This temperature will hold latent heat storage elements during the phase transition with little deviation.
- the value of the respective setpoint temperature results from the latent heat storage material of the latent heat storage element used.
- the plural "latent heat storage elements” is used in the present case, this is because in the vast majority of applications in the In fact, a plurality of main latent heat storage elements, usually at least two main latent heat storage elements, are used. In the patent law sense, however, the plural “latent heat storage elements” should also include the singular "latent heat storage element". Of course, the invention is also relevant if, exceptionally, only exactly one main latent heat storage element should be located in the receiving space of the transport container.
- the heat insulation for the receiving space can be done in all usual ways. Particularly useful is the use of vacuum insulation panels as part of the thermal insulation. Also in this respect, reference is made to the prior art WO 2014/094995 A2 explained in the introduction, but also to WO 2004/104498 A2. For vacuum insulation panels, special reference is also made to DE 100 58 566 C2, which is based on the applicant of the present application.
- the transport container is prepared by fitting the receiving space with the already preconditioned main latent heat storage elements required for the desired heat capacity. This ensures that the temperature in the receiving space quickly reaches the target temperature range. This placement is carried out at a specific location, the placement location.
- the transport container After loading, the transport container is ready to receive a cargo in the receiving space.
- the filling of the receiving space of the transport container with cargo also happens at a certain place, the filling place.
- the filling point can be the same place as the place of assembly, but often the filling location is located at a distance from the place of assembly. This is particularly the case when the preparation of the transport container takes place at the place of assembly at the supplier of the transport container, while the filling of the receiving space of the transport container takes place with the relevant cargo at the customer of the supplier, for example, the pharmaceutical company, the in-house sensitive pharmaceuticals in the receiving space of the transport container fills.
- a transport container is used with a target period of 96 h, such a transport container of course already has a safety buffer from the manufacturer, so that it is ensured that even under unfavorable conditions, the target period is met.
- the safely maintained target time would be 96 hours, that is four full days, with an additional safety margin of e.g. 4 h. If one has to expect that the transfer period is greater, then one can no longer be sure that during transportation with the transport container, the cargo is actually transported to the end in the desired temperature range. Consequently, in the prior art, the manufacturer or supplier specifies exactly when a transport container must be filled after loading the receiving space. This exact specification is sometimes considered to be limiting and it is therefore an object of the present invention to improve upon the prior art method of preparing a shipping container for greater flexibility in the transfer period.
- the above-mentioned object is achieved in a method for preparing a transport container having the features of the preamble of claim 1 by the features of the characterizing part of claim 1.
- additional energy storage elements are introduced into the receiving space in addition to the intended for the proper transport of the cargo in the receiving space and precalculated in terms of the necessary heat capacity main latent heat storage elements at the placement. ever after the expected transfer period, the heat capacity added by the additional energy storage elements, the additional heat capacity, is adjusted such that from the time of filling the receiving space with the transported goods in any case, the full target time interval with the target temperature range available stands.
- the linguistically used plural includes the singular patent law; a single additional energy storage element is sufficient to realize the teachings of the invention. It is important that an additional, not to the target period, but on the transfer period tuned additional heat capacity is introduced into the receiving space of the transport container, through which the transfer period can be bridged.
- additional energy storage elements it may be advisable to keep them at a lower temperature than the target temperature of the main latent heat storage elements, provided that it must be prevented in any case that the target temperature range is left towards higher temperatures.
- the additional target temperature of the additional energy storage elements may not be too low to prevent hypothermia of the transported cargo to be introduced later.
- the additional energy storage elements all types of energy storage elements come into question. Important is only a sufficient specific or latent heat energy of the material of this additional energy storage elements. It does not necessarily have to be latent heat storage elements. For example, it can be a container with very cold, but still liquid water, a cheap, non-frozen gel battery pack or other material with high heat capacity. It is also possible to use active energy storage elements to which energy is actively supplied. According to a preferred teaching of the invention, however, it is provided that also latent heat storage elements are used as additional energy storage elements.
- latent heat storage elements so both as a main latent heat storage elements and as additional latent heat storage elements, typically all systems of the prior art in question. If one lies at a target temperature (temperature of the phase transition) of about 0 ° C, so you can use water with different additives as latent heat storage material. For cold storage below 0 ° C suitably prepared salt solutions are used.
- a latent heat storage element according to the present invention is a latent heat storage material in a closed, possibly also provided with a pressure equalization valve enclosure. This is also referred to as a macroencapsulated PCM material.
- the wrapping is often made of plastic.
- the additional energy storage elements are removed from the receiving space at the filling location before or during filling.
- the heat capacity of the additional energy storage elements at the filling location that is removed before filling from the receiving space. This guarantees exactly defined boundary conditions for the actual transport of the cargo under the influence of the main latent heat storage elements.
- At least one of the additional energy storage elements removed from the receiving space before or during filling is reused, for example for equipping another transport container. Accordingly, in the method according to the invention, additional energy storage elements used previously (once or several times) can already be introduced into the receiving space. Alternatively, the additional energy storage elements removed from the receiving space are disposed of.
- one of the additional energy storage elements or several or all additional energy storage elements can be left in the receiving space during and after filling.
- the inventive method requires a certain additional effort, which does not have to be operated in all cases. Then, if one can almost certainly assume that the safety margin in the design of the transport container includes the transfer period, one does not have to do the extra work. Consequently, it is recommended according to the preferred teaching that the method (only) is used when the expected transfer time exceeds a certain proportion of the target period, in particular more than about 4%, especially more than about 10% of Target period is.
- the method according to the invention will probably already be used for a transfer period of at least 1 h or of at least 2 h.
- the additional energy storage elements can be arranged so that they are in contact with one or more main latent heat storage element (s). For example, lie the additional energy storage elements on one or more main latent heat storage element (s).
- At least one of the additional energy storage elements is provided with a spacer, so that this additional energy storage element has no contact with the main latent heat storage elements or maintains a minimum distance to the main latent heat storage elements. This procedure ensures a more even distribution of the heat energy of the additional energy storage element.
- EPP expanded polypropylene
- EPS expanded polystyrene
- PU polyurethane
- an embodiment of the method according to the invention is recommended in such a way that the main latent heat storage elements and, if present, the vacuum insulation panels at the place of assembly are tested for functionality and compliance with nominal values.
- heat insulations that are mechanically so dense on the outside that they can serve as an outer sheath at the same time. Otherwise, it is expedient that in addition a heat insulation outside surrounding outer sheath is provided, which can also be opened to fill the receiving space and to be able to empty.
