Description

[0001] This invention relates to the field of ventilation management, and in particular to ventilation management in temperature control systems (e.g., Peltier systems) used to control the temperature of the internal space of a device.

[0002] Units with temperature control systems (e.g., laboratory units) are often installed in a space-optimized manner and sometimes in poorly air-conditioned rooms. This can negatively impact the exhaust management of the temperature control system and limit its performance. For example, available space in laboratory rooms (e.g., laboratory and pharmaceutical laboratory rooms) is typically limited, and laboratory units (e.g., incubators, refrigerators, freezers, climate cabinets, ovens) are accordingly installed in a space-optimized manner and usually have minimum permissible distances from walls. Furthermore, laboratory air conditioning is not always optimally designed, so the conditioned ambient temperature in the laboratory may be significantly higher than the standard value of 22°C.

[0003] Some installations, such as climate control units, are equipped with Peltier systems for temperature control, i.e., for cooling and heating the interior space. These Peltier systems generate exhaust air that is heated or cooled, in contrast to supply air. For example, waste heat is generated during cooling, which is dissipated via the corresponding exhaust air. The maximum cooling or heating performance of a Peltier system depends particularly on heat exchange with the environment, and therefore on the temperature of the supplied ambient air. In principle, this also applies to other temperature control systems that rely on heat exchange with the supplied ambient air, such as compressor refrigerators. In principle, it is desirable for installations equipped with temperature control systems for cooling and heating via ambient air to consistently achieve their maximum cooling and heating performance, even under harsh installation conditions (with minimal wall clearance and threshold ambient temperature) and / or poor air conditioning of the ambient air.

[0004] However, in known devices, warm or cold air may accumulate, especially at the rear of the device, and / or the exhaust air from the temperature control system may mix unfavorably with the air supplied to the temperature control system.

[0005] For cooled laboratory equipment (e.g., freezers or climate chambers), it is known to spatially separate waste heat from the corresponding laboratory equipment, which can be achieved, for example, through water cooling. To this end, a water cooler is installed outside the laboratory area and connected to the cooled laboratory equipment via water pipes, so that the equipment's waste heat is dissipated directly via water. While this advantageously avoids waste heat within the laboratory area, it is disadvantageous because this solution requires additional installation work from the laboratory user and additional design work for the water-cooled laboratory equipment, which is far more complex, requires more materials, and is therefore more expensive.

[0006] Therefore, one object of the present invention is to overcome or at least mitigate the disadvantages and defects of the prior art. Generally speaking, the object of the present invention may be to improve the exhaust management in devices with temperature control systems, particularly laboratory devices with Peltier systems.

[0007] This objective is achieved through the subject matter of the invention. Advantageous further developments of the invention are described by way of the claims, the following description, and the accompanying drawings.

[0008] In a first aspect, the present invention relates to an apparatus comprising at least one temperature control system for temperature control of an internal space of the apparatus, wherein each of the at least one temperature control system comprises an external heat exchanger disposed on the outside of the apparatus, the heat exchanger being designed to exchange heat between the temperature control system and supply air conducted via the external heat exchanger. Furthermore, the apparatus includes an air guiding unit that draws in exhaust air from the respective external heat exchanger of the at least one temperature control system and conducts it away from the respective external heat exchanger.

[0009] In other words, the present invention relates to an apparatus designed for controlling the temperature of an interior space and comprising at least one corresponding temperature control system. The temperature control system is designed to exchange heat with supplied air via an external heat exchanger disposed on the outside of the apparatus. Furthermore, the apparatus specifically includes an air guiding unit that receives exhaust air from the external heat exchanger, i.e., the supplied air that has been conducted and heated or cooled via the external heat exchanger, and conducts it away from the temperature control system. It should be understood that the term "conducts it away" also includes passive conduction, meaning that the air guiding unit does not necessarily actively conduct the exhaust air away. For example, the air guiding unit may also passively conduct the exhaust air away by utilizing thermal convection and may be designed, for example, as a channel.

[0010] In embodiments of the invention, the air guiding unit may be configured to spatially separate exhaust and supply air in the area of ​​at least one temperature control system. This advantageously prevents exhaust and supply air from mixing.

[0011] In embodiments of the invention, the air guiding unit may be arranged at least partially on the same outer side of the device, and at least one external heat exchanger of the temperature control system may be arranged on that outer side. This allows the external heat exchanger to be incorporated into the air guiding unit.

[0012] In embodiments of the invention, the air guiding unit may be configured to include at least one supply opening for supplying air. Therefore, the supply opening can allow for both active and / or passive supply of air.

[0013] In embodiments of the invention, the air guiding units may be configured to house at least one external heat exchanger of the temperature control system. This advantageously allows exhaust air to be collected in the air guiding unit and conducted away through it.

[0014] In embodiments of the invention, an external heat exchanger for at least one temperature control system may be arranged on the rear side of the device, and an air guiding unit may be arranged at least partially on the rear side of the device. This advantageously allows the air guiding unit to receive exhaust air from at least one temperature control system.

[0015] In embodiments of the invention, the air guiding unit may be configured to include at least one outlet opening through which exhaust air is discharged to the environment of the device. In other words, the air guiding unit can discharge exhaust air received from at least one temperature control system (particularly each of the external heat exchangers in the external heat exchangers) to the environment of the device via at least one outlet opening. In embodiments of the invention where the air guiding unit further includes at least one supply opening, the at least one supply opening and at least one outlet opening may be arranged on different sides of the device. This allows for an advantageous reduction of mixing between supply and exhaust air, since the exhaust and supply air are spatially separated. Alternatively or additionally, in corresponding embodiments, the at least one supply opening and at least one outlet opening may be oriented in opposite directions.

[0016] In embodiments of the invention, the air guiding unit may be arranged at least partially on the upper side of the device. Alternatively, the air guiding unit may be arranged at least partially on the lower side of the device. Furthermore, alternatively, the air guiding unit may be arranged at least partially on the side surface of the device. In other words, the air guiding unit may be arranged at least partially on at least one of the upper, lower, and / or two side surfaces of the device. This can advantageously enable the exhaust air to be directed away from the rear side of the device, and thus spatially separate the supply opening and the outlet opening, in order to reduce or preferably minimize the mixing of supply and exhaust air.

[0017] In embodiments of the present invention, the air guiding unit may be configured to include at least one air guiding element. In other words, the air guiding unit may include one or more air guiding elements; specifically, the air guiding unit may also consist of a single air guiding element.

[0018] In embodiments of the invention, the device may be configured to include multiple temperature control systems, and the air guiding unit may include multiple air guiding elements, wherein each air guiding element receives exhaust air from at least one heat exchanger of the multiple temperature control systems.

For example, a first portion may be disposed on the rear side of the device, while a second portion may be disposed on another outer surface of the device. In particular, the plurality of interconnected air guiding element portions may be disposed on at least two different outer sides of the device.

Specifically, in such embodiments, corresponding air guiding elements may be provided to conduct the airflow to each temperature control system.

[0029] In embodiments of the invention, the air guiding unit may be configured to include at least one exhaust fan designed to exhaust air from at least one temperature control system. This at least one exhaust fan may preferably allow active exhaust air discharge and / or conduct it away, and, if necessary, also provide air supply through a corresponding suction pipe. For example, exhaust fans may be provided to discharge exhaust air from multiple temperature control systems, or an exhaust fan may be provided for each of the at least one temperature control system. Preferably, at least one exhaust fan may be provided for each outlet opening.

[0030] In embodiments of the invention, at least one temperature control system may be configured to further include an internal heat exchanger arranged within the interior space of the device and designed to exchange heat between the at least one temperature control system and supply air conducted via the internal heat exchanger.

Thus, the internal heat exchanger advantageously allows heat exchange between the air contained within the interior space of the device and the internal heat exchanger, thereby cooling or heating the interior space.

[0031] Furthermore, the internal and external heat exchangers can be configured to be thermally separated from each other. This allows the two heat exchangers to have different temperatures.

[0032] In embodiments of the invention, at least one temperature control system may be configured to further include at least one fan designed to supply air to an internal heat exchanger. Alternatively, at least one temperature control system may include at least one fan designed to supply air to an external heat exchanger. For example, the fan may be permanently attached to the external heat exchanger and protrude through a supply opening in an air guiding element to draw in air and blow it onto the external heat exchanger. The fan designed to supply air to the external heat exchanger may be mounted such that air is provided to the external heat exchanger through the supply opening. It should be understood that air can be supplied to the heat exchanger by blowing air into the heat exchanger or by drawing air into the heat exchanger.

[0033] In embodiments of the present invention, the external heat exchanger and / or the internal heat exchanger may be configured as a radiator.

[0117] It should be noted that not all figures have all reference numerals. Instead, for brevity and ease of illustration, some reference numerals have been omitted from some figures. Embodiments of the invention will now be described with reference to the accompanying drawings.

[0118] The invention is described below with particular reference to laboratory apparatus having a Peltier system for cooling or heating. However, it should be understood that this is purely exemplary, and the invention relates more generally to apparatus having a temperature control system. This means that the invention is not limited to laboratory apparatus, but may also include, for example, incubators, refrigerators, and freezers used not in laboratories but in homes and / or various industries. In addition to the Peltier system, the temperature control system may also include an air-cooled compressor refrigeration unit.

[0119] Generally, the devices according to the invention include at least one temperature control system designed to control the temperature of the internal space of the device. Therefore, these devices may also be referred to as temperature control cabinets.

[0120] Figure 1An exemplary embodiment of a Peltier element 1, which can be used for heating and / or cooling, is shown. Essentially, the Peltier element 1 is an electrothermal converter based on the Peltier effect. The Peltier element 1 causes a temperature difference to be generated between its two outer portions 12, 14 when current flows through it. In other words, the Peltier element 1 is designed such that when current flows through it, the first outer portion 12 is cooled and the other (preferably opposite) second outer portion 14 is heated (or vice versa), thus providing a temperature difference between the two outer portions. Which outer portion is cooled and which is heated depends on the direction of current flow. The two outer portions are typically opposite to each other. For the power source, the Peltier element 1 typically has a corresponding connector 16, such as a conductor 16.

[0121] Figure 2 An example of a Peltier system 100 as a possible embodiment of a temperature control system is shown. The Peltier system 100 includes at least one Peltier element 1 (not shown) thermally connected to two heat exchangers 102, 104, such as radiators 110, 120. Specifically, each heat exchanger 110, 120 is thermally connected to an external portion 12, 14 of at least one Peltier element 1. This allows the respective heat exchangers 110, 120 to exchange heat between the thermally connected external portions 12, 14 and a supplied fluid (e.g., ambient air).

[0122] For example, when the outer portion 12 of the Peltier element 1 is cooled, the heat exchanger 110 connected thereto can cool the fluid supplied to the heat exchanger 110 or conduct the heat of the supplied fluid to the outer portion 12 of the Peltier element 1. At the same time, the heat exchanger 120 thermally connected to the corresponding heated outer portion 14 of the Peltier element 1 can transfer the heat of the Peltier element to the fluid supplied to the heat exchanger 120, such as ambient air.

[0123] The Peltier system 100 may further include at least one fan 112, 122 for at least one associated heat exchanger 110, 120. The at least one fan may preferably supply fluid, such as ambient air, to the respective heat exchanger 110, 120. In other words, according to an embodiment, the Peltier system 100 may include at least one fan 112, 122 for at least one of the heat exchangers 110, 120. In some embodiments, the Peltier system 100 may include at least one fan 112, 122 for each heat exchanger 110, 120.

[0124] Heat exchangers 110 and 120 are thermally isolated from each other (except for thermal connections that are present in principle via at least one Peltier element).

[0125] In principle, the Peltier element can also be used to heat the laboratory apparatus by reversing the direction of the current. However, since heating of the laboratory apparatus can also be achieved, for example, by a simple resistance heater, the invention is described below specifically with regard to cooling of the laboratory apparatus.

[0126] Therefore, for example, the Peltier system 100 can cool the air inside the laboratory apparatus. For this purpose, at least one Peltier element 1 of the Peltier system 100 is powered and, for example, ambient air is supplied to two heat exchangers 110 and 120 via fans 112 and 122. The Peltier system 100 is arranged such that one heat exchanger 110 is located inside the laboratory apparatus, while the other heat exchanger 120 is located outside the laboratory apparatus. Therefore, the internal heat exchanger 110 and the external heat exchanger 120 are also referred to hereinafter. This allows heat to be removed from the interior space of the laboratory apparatus and heat to be supplied to the environment surrounding the laboratory apparatus (and vice versa).

[0127] To cool the laboratory apparatus, the direction of the current flowing through at least one Peltier element 1 of at least one Peltier system 100 is selected such that an internal heat exchanger 110 is thermally connected to a cooled external portion 12 of at least one Peltier element 1, and an external heat exchanger 120 is thermally connected to a heated external portion 14 of at least one Peltier element 1 (see [link to relevant documentation]). Figure 3 ).

[0128] Therefore, the internal air supply 114 from the laboratory apparatus, supplied to the internal heat exchanger 110 via fan 112, is cooled by the heat contained in the air being dissipated via the heat exchanger 110 to the cooled external portion 12 of at least one Peltier element 1. The corresponding cooled internal exhaust air 116 of the heat exchanger 110 then cools the interior space of the laboratory apparatus. Waste heat generated at another external portion 14 of at least one Peltier element 1 is dissipated via a thermally connected heat exchanger 120, which, for example, is supplied with external air supply 124 via a corresponding fan 122. This air extracts heat from the heat exchanger 120, i.e., is heated, and then discharged as warm external exhaust air 126.

[0129] It is advantageous for heat dissipation from the heated external portion 14 of at least one Peltier element 1, because the minimum temperature of the cooled external portion 12 is limited by the maximum achievable temperature difference via at least one Peltier element 1, which is constrained by the temperature of the heated external portion 14. Therefore, the cooling performance of the Peltier system is also limited by the temperature of the heated external portion 14, making efficient cooling of the external portion 14 advantageous. The cooling performance of the external heat exchanger 120 depends primarily on the temperature of the supplied external supply air 124; if it mixes with the external exhaust air 126 of the external heat exchanger 120, the temperature of the supply air 124 increases, and the cooling performance via the external heat exchanger 120 decreases. It should be understood that the above statements, with necessary modifications to the details, also apply to other temperature control systems whose performance typically depends on and may be limited by heat exchange with ambient air. For example, the cooling performance of a compressor refrigeration unit also depends on the cooling air supplied for cooling the external heat exchanger 120.

[0130] As already explained, it is therefore disadvantageous if a device (e.g., a laboratory device) that includes at least one temperature control system (e.g., a Peltier system) supplying ambient air is placed at a minimum distance from a wall, as this could lead to heat buildup and air mixing. For example, Figure 3 This was illustrated using laboratory equipment. Insufficient air conditioning at the equipment's installation location could further exacerbate these problems.

[0131] refer to Figure 3 The laboratory apparatus 20 is equipped with, for example, two Peltier systems 100 on its rear side 24, which are designed to cool the interior space 22 of the laboratory apparatus 20. The rear side is opposite to the front side 28, from which the interior space can be accessed, for example, through a door. An upper Peltier system 100o is arranged in the upper region of the rear side 24 of the laboratory apparatus 20, and a lower Peltier system 100u is arranged in the lower region of the rear side 21 of the laboratory apparatus 20. Alternatively, the laboratory apparatus 20 may also include, for example, four or more Peltier systems 100, preferably two or more upper and lower Peltier systems arranged adjacent to each other. The laboratory apparatus 20 is typically installed with the minimum permissible distance between the rear side 21 of the laboratory apparatus 20 and the wall 30 and / or between the upper side 26 of the laboratory apparatus and the ceiling 32. In order to cool the interior space 22, the air supply 114 from the interior space 22 of the laboratory device 20 is supplied by a corresponding fan 112 to an internal heat exchanger 110 cooled by at least one Peltier element 1, and is cooled by the internal heat exchanger 110 so that the subsequently cooled interior exhaust air 116 flows back into the gradually cooled interior space 22.

[0132] Disadvantageously, the external exhaust 126 of the external heat exchanger 120 on the rear 24 of the laboratory unit 20, which is designed to remove heat from the Peltier system 100, has difficulty mixing with the ambient air of the surrounding room due to the walls 30 and ceiling 32. Instead, there is a risk that the external exhaust 126 will accumulate in the spaces between the rear 24 of the laboratory unit 20 and the walls 30, and between the upper 26 of the laboratory unit and the ceiling 32, and in particular, will mix with the external supply air 124 drawn in by the corresponding fan 122 to cool the Peltier system 100, thus adversely reducing the cooling performance of the external heat exchanger 120.

[0133] refer to Figure 4a and Figure 4b According to an embodiment of the invention, this problem is solved by spatially separating the external exhaust air 126 from the external supply air 126 supplied, for example, via a fan 122, for cooling the Peltier system 100. In particular, the external exhaust air 126 in the area of ​​the Peltier system 100 (i.e., the rear side 24 of the laboratory device 20) can be specifically collected and discharged, for example, delivered.

[0134] To separate supply and exhaust air, an air guiding unit 40 can be provided, which receives external exhaust air 126 from at least one Peltier system 100 and directs it away from the intake area of ​​external supply air 124. (Reference) Figure 4a The air guiding unit 40 may, for example, be attached to the rear side 24 of the laboratory apparatus 20 and collect external exhaust air 126 and discharge it toward the upper side 26 of the laboratory apparatus. Specifically, the air guiding unit 40 may include at least one air guiding element 41, which is correspondingly attached to the rear side of the laboratory apparatus 20. The rear air guiding element 41 may also be referred to as a first air guiding element portion 42. In particular, to advantageously reduce the minimum distance from the laboratory ceiling 32, external exhaust air may also be directed toward the front side 28 of the laboratory apparatus. For this purpose, the air guiding element 41 may include a second air guiding element portion 44.

[0135] In other words, the device includes an air guiding unit 40, which includes at least one air guiding element 41. At least one of the at least one air guiding element 41 may also include a plurality of air guiding element portions 42, 44.

[0136] refer to Figure 4bThe air guiding element 41 may accordingly include a first air guiding element portion 42 on the rear side 24 of the laboratory apparatus 20 and a second air guiding element portion 44, for example, disposed on the upper side 26 of the laboratory apparatus 20. It should be understood that the first air guiding element portion 42 and the second air guiding element portion 44 are fluidly connected to each other to form the air guiding element 44. Alternatively, the second air guiding element portion 44 may also be disposed, for example, on a side surface of the laboratory apparatus or on the lower side 29 of the laboratory apparatus.

[0137] Air guiding unit 40 can receive exhaust air from the external heat exchanger 120 of the corresponding Peltier system 100. The external heat exchanger 120 of the corresponding Peltier system 100 can be housed in at least one air guiding element 40, particularly in a first air guiding section. If the air guiding unit 40 includes multiple air guiding elements 41, and the device includes multiple Peltier systems, each air guiding element can receive exhaust air from at least one heat exchanger of multiple temperature control systems. To allow the supply air 124, the air guiding unit or at least one air guiding element can include a corresponding supply opening 46, which, for example, allows the fan 122 of the Peltier system 100 to be located outside the air guiding unit or air guiding element, such as... Figure 5 As shown in a). Alternatively, the fan 122 may also be located within the air guiding unit 40 or the air guiding element 41 and draw in air only through the supply opening 46 (see a). Figure 5 (b)

[0138] Generally, the dimensions of at least one air guiding element 41 of the air guiding unit 40, and particularly the first air guiding element portion 42, can be set such that at least the external heat exchanger 120 can be accommodated therein, i.e., can be covered by the air guiding element 40. If at least one Peltier system 100 includes a fan 122 for supplying external airflow 124, it can be arranged outside the air guiding element 40. Figure 5 a) or inside the air guiding element 41 ( Figure 5 (b)). In the first case, the fan 122 is arranged outside the air guiding element 40 (see Figure 5 (a) ), the air guiding element 40 may have a depth of at least 50 mm. In the second case, the fan 122 is arranged inside the air guiding element 40 (see [reference]). Figure 5 (b) The air guiding element 40 may have a depth of at least 85 mm. In any case, at least one air guiding element 40 includes at least one supply opening 46 through which external air supply 124 can be provided (e.g., drawn in).

[0139] The air guide element can have a width ranging from 200mm to 2000mm, for example, a width ranging from 500mm to 1200mm. The air guide element can have a height ranging from 700mm to 2000mm, for example, a height ranging from 1200mm to 2000mm.

[0140] The air guiding unit 40 may include air guiding elements (e.g., air baffles) designed to influence (i.e. manipulate) the airflow within the air guiding unit 40 or at least one air guiding element 41. Thus, the airflow above at least one external heat exchanger can be preferably improved by the air guiding elements, and optimized relative to the heat transfer pipeline if necessary.

[0141] Alternatively, a central supply fan may be provided, which supplies air to all Peltier systems via a supply opening, preferably at the bottom of the rear side of the laboratory apparatus. The air supply can then be distributed to the respective Peltier systems 100, preferably via corresponding air guide elements.

[0142] The air guiding unit or at least one air guiding element may also include at least one outlet opening 48 through which exhaust air is discharged into the environment of the laboratory apparatus. Preferably, the at least one outlet opening 48 is attached to a side of the laboratory apparatus different from the at least one supply opening 46. Alternatively or additionally, the at least one outlet opening 48 may preferably be oriented in a direction opposite to the at least one supply opening 46. These arrangements of the supply and outlet openings can advantageously prevent or at least mitigate or reduce the mixing of exhaust air with supply air.

[0143] As a complement to or alternative to at least one fan 122 of at least one Peltier system, the air guiding unit 40 may include at least one exhaust fan designed to draw in and exhaust external exhaust air 126. This at least one exhaust fan may also supply external airflow 124 by exhausting external exhaust air 126, thus eliminating the need for a corresponding fan 122 in at least one Peltier system 100. The at least one exhaust fan may be located, for example, at at least one outlet opening 48 or may be located within the air guiding element 40.

[0144] The provision of a second air guiding element portion 44 on the upper side 26, side surface, or lower side 29 of the laboratory apparatus advantageously allows the external exhaust air 126 to be directed away from the rear side of the laboratory apparatus towards the front side 28 opposite to the rear side 24 of the laboratory apparatus 20. Therefore, the external supply air 124 can be drawn in via at least one external fan 126 of the Peltier system 100, which does not mix with the external exhaust air 124 and is particularly colder, thus achieving a higher efficiency than the external exhaust air 124 at the same ambient temperature and the same distance from the wall. Figure 3 The example in the text provides better cooling performance. Preferably, at least one supply opening may be arranged in the first air guiding element portion 42, and at least one outlet opening may be arranged in the second air guiding element portion 44.

[0145] By providing a second air guiding element portion 44 to the air guiding element of the air guiding unit, a smaller minimum distance can be advantageously achieved, particularly between the upper side of the device and the ceiling. Therefore, the provision of the second air guiding element portion 44 may be particularly relevant for installation locations where a sufficient height distance from the laboratory ceiling cannot be achieved. For example, if a minimum distance of 570 mm from the laboratory ceiling is required without the second air guiding element portion 44, this minimum distance can be reduced to 300 mm (or less), for example, if the second air guiding element portion 44 is provided.

[0146] Figure 6 An example of an air guide element 40 including a single air guide element 41 is shown. The air guide element also corresponds to a first air guide element portion 42, which in some embodiments may also represent the entire air guide element (see [link]). Figure 4a The air guiding element portion 42 is intended for use with four Peltier systems and therefore has four supply openings 46. The first air guiding element portion 42 can be attached to the rear side of the laboratory apparatus, such as, for example... Figure 4a and Figure 4b As shown, the first air guiding element portion 42 and the rear side of the laboratory device are provided with a space or cavity, in which exhaust 126 is separated from supply 124, and air is supplied and discharged via supply opening 46 and the resulting outlet opening. Therefore, the first air guiding element portion 42, and more generally the air guiding element 41 or air guiding unit, can provide a cavity together with the outside of the laboratory device in which exhaust air from the Peltier system can be collected and discharged / conducted away.

[0147] The air guiding unit 40 is preferably made of metal, such as galvanized steel sheet. In some embodiments, the air guiding unit 40 may be at least partially insulated. This can advantageously reduce heat exchange between the external exhaust air 126 and the external supply air 124 via the material of the air guiding unit 40.

[0148] In some embodiments, the air guiding unit 40 and therefore at least one air guiding element 41 may have additional openings, such as passive supply openings that allow air to be supplied via thermal convection. The corresponding passive supply openings may preferably be arranged below the Peltier system 100.

[0149] In embodiments of the laboratory apparatus that include multiple Peltier systems, the air guiding unit may include multiple air guiding elements, each receiving exhaust air from at least one Peltier system. In other words, the invention is not limited to the apparatus and, in particular, not limited to an air guiding unit that includes only one air guiding element, but the laboratory apparatus may also include multiple air guiding elements, wherein each air guiding element receives at least exhaust air from a Peltier system and thus receives corresponding exhaust air from at least one heat exchanger 120.

[0150] If the air guiding unit includes multiple air guiding elements, these air guiding elements can also be arranged along different outer sides of the laboratory apparatus. In particular, corresponding second air guiding element portions 44 can be arranged on different outer surfaces of the laboratory apparatus, for example, on two side surfaces of the laboratory apparatus.

[0151] The device can be substantially designed to control and / or regulate the temperature within the internal space of the device. To this end, the device may include a control unit designed to control and / or regulate at least one temperature control system (preferably individually). For example, different temperature zones may be permitted within the internal space of the device.

[0152] The improvements achieved by the present invention are also evident in comparative measurements of laboratory apparatuses with and without corresponding air guiding units 40. These comparative measurements were performed using a laboratory apparatus 20 having four Peltier systems 100 arranged on the rear wall of the laboratory apparatus. The corresponding arrangement is as follows: Figure 7 As shown, where Figure 7 a) shows a rear view of the laboratory apparatus, and Figure 7 b) shows a side view of the laboratory apparatus.

[0153] Four Peltier systems 100 are arranged in two rows and two columns on the rear side 24 / rear wall of the laboratory apparatus 20. In other words, the Peltier systems 100 are arranged such that there is another Peltier system 100 next to, above or below each Peltier system 100.

[0154] Figure 7 b) shows the laboratory apparatus in a side view, wherein... Figure 7 Unlike a), an air guiding unit 40 is also shown on the rear side 24 of the laboratory apparatus 20. The air guiding unit 40 includes a single air guiding element 41.

[0155] For test measurements, the distance d from the sidewall is 150mm laterally. S and the distance d between the air guiding element 40 on the rear side 24 of the laboratory apparatus and the rear wall 200mm. R To place the laboratory equipment. Then, at the location of the second air guiding element portion 44 and the distance d between the upper side of the second air guiding element portion 44 and the ceiling (300mm). D In both cases, and in the absence of the second air guiding element portion 44 and the distance d between the upper side and the ceiling of 565mm. D Measurements were performed under the same conditions. The results obtained from the two experimental settings were comparable.

[0156] It goes without saying that because the laboratory apparatus is mounted on appropriate rollers, there is free space underneath it, so there may also be a certain amount of air circulation on the lower side of the apparatus between the front and rear sides of the laboratory apparatus.

[0157] During the experimental measurements, temperatures were recorded at various points both inside and outside the laboratory apparatus. Specifically, the temperatures of the air supplied to and discharged from the Peltier system 100, as well as the exhaust air temperature at the outlet opening of the air guiding element, were recorded. Additionally, the ambient temperatures outside and inside the laboratory apparatus were recorded.

[0158] At an ambient air temperature of 28°C, without the corresponding air guiding element 40, the internal space 22 of the laboratory apparatus 20 can only reach a temperature greater than 0°C (see [reference]). Figure 3 By using appropriate air guiding elements, the temperature inside the laboratory apparatus can reach 0°C under the same ambient temperature (see [reference]). Figure 4a and Figure 4bSpecifically, by using the air guiding element 40, the temperature of the external exhaust air 126 can be reduced by approximately 2°C to 4°C, and the temperature of the external supply air 124 can be reduced by approximately 5°C to 7°C. Furthermore, by providing the air guiding element 40, the temperature difference between the external supply and external exhaust air between the upper Peltier system 100o and the lower Peltier system 100u can be eliminated; without the air guiding element 40, the temperature of the lower Peltier system 100u is higher than that of the upper Peltier system 100o. This demonstrates the advantageous effects of the invention, which is particularly relevant for laboratory installations in laboratory rooms with limited space and sometimes poor air conditioning.

[0159] This invention advantageously prevents heat buildup and undesirable air mixing in at least one area of ​​a temperature control system (e.g., the intake area of ​​at least one external fan 122 of a Peltier system 100). This advantageously allows for maximum cooling and heating performance of the device (e.g., a Peltier climate cabinet) even at minimal distance between the rear wall 24 of the device and the wall 30 of the installation room, and additionally at critical ambient temperatures, because spatial separation prevents or reduces mixing of exhaust and supply air, and the supply air temperature corresponds almost exactly to the ambient temperature of the installation room. In the example above, this means that the intake temperature of the Peltier external fan 122 corresponds almost exactly to the ambient temperature of the installation room. Furthermore, the warm external exhaust 126 can also advantageously reduce the risk of the CO2 sensor and / or humidity sensor mounted above the device dropping below the dew point.

[0160] In other words, by spatially separating exhaust and supply air, for example, the areas “Peltier external radiator (Peltier waste heat)” and “Peltier external fan intake (ambient temperature)”, the present invention advantageously eliminates the potential heat accumulation and air mixing, such as Peltier waste heat air 126, in the rear wall area 24 of the corresponding device 20 (e.g., climate cabinet) by separating exhaust and supply air through the temperature control system (especially in the case of multiple temperature control systems).

[0161] Whenever relative terms such as “about,” “substantially,” or “essentially” are used in this specification or claims, such terms should be interpreted to include precise terms as well. That is, for example, “substantially straight” should be interpreted to also include “(completely) straight.”

[0162] Where steps are mentioned in the foregoing and / or appended claims, it should be noted that the order in which steps are listed herein may be random. That is, unless otherwise stated or obvious to those skilled in the art, the order in which steps are listed may be random. For example, if this document indicates that the method includes steps (A) and (B), this does not necessarily mean that step (A) occurs before step (B), but it could mean that step (A) is performed (at least partially) simultaneously with step (B), or that step (B) occurs before step (A). Furthermore, when it is mentioned that step (X) precedes another step (Z), this does not mean that there are no steps between steps (X) and (Z). That is, step (X) preceding step (Z) includes cases where step (X) is performed directly before step (Z), and cases where (X) is performed before one or more steps (Y1), ..., followed by step (Z). Corresponding considerations also exist when using terms such as "after" or "before".

[0163] The preferred embodiments have been described above in conjunction with the accompanying drawings. However, those skilled in the art will understand that such embodiments are provided for illustrative purposes only and should not be construed as limiting the scope of the invention as defined in the claims.
