Thermal cooling in the luminaire housing

Published

News

There are very high hygiene requirements in operating rooms. Not only for personnel or ventilation and air conditioning. They also apply to the equipment used there. Operating room luminaires, for example, have to meet strict specifications. Under these special conditions, Merkle & Partner developed an internal cooling concept for an OR LED luminaire together with a luminaire manufacturer on the basis of a flow-oriented simulation calculation.

In principle, it would be a simple matter to give a product such as a luminaire more surface area in order to increase heat exchange with the environment. However, ribbed surfaces, for example, are not allowed on luminaires used in operating rooms because, among other things, uncontrollable dust formation must be avoided. The pure, smooth stainless steel surfaces of the luminaire must also not emit heat or generate air currents to the outside. Since the dimensions of the luminaire body cannot be oversized either, a new solution had to be found for an internal cooling concept; based on simulation using computational fluid dynamics.

Here, the luminaire including all components as well as their properties are mapped in a simulation in order to work out a sensible cooling concept. Not only is the air circulation inside the luminaire visualized realistically, but temperature differences and changes with changing geometries or ventilation rates are also reproduced.

To ensure that the air is not only moved but also directed to the heat sources in a targeted manner, the necessary geometry of the luminaire’s internal structure was optimized by means of a flow calculation. The placement of components for optimal heat distribution within the luminaire was also optimally designed. The surgical luminaire thus offers an internal cooling concept that is so well designed that the luminaire meets all the requirements for use in the operating room.

 

“Economically, in terms of time, but also functionally, the design using computational fluid dynamics (CFD) offers the optimal solution. Digital test models can be used to identify sensible, but also less sensible, paths at an early stage and to develop innovative cooling concepts. It is no longer just a question of the time savings offered by simulation calculations. Rather, digital concepts can be developed that perhaps would not have been discovered via real trials.”

Wastewater treatment plant in Tübingen now has fourth treatment stage

Published

on

On July 21, 2021, Helmfried Meinel, Ministerial Director at the Baden-Württemberg Ministry of the Environment, visited the wastewater treatment plant in Tübingen, where he inaugurated the construction of the so-called fourth treatment stage. The fourth treatment stage will allow residues of pharmaceuticals and household chemicals to be filtered out of wastewater. “The elimination of trace substances is precautionary water protection,” Meinel emphasized. In Tübingen in particular, this plays a major role, he said, because it means that fewer trace substances end up in the Neckar River.

The Ministerial Director explained that Tübingen is only the second wastewater treatment plant in Baden-Württemberg, after the treatment plant in Eriskirch, to use an ozonation plant with downstream filtration for the elimination of trace substances. “Tübingen is thus one of the pioneers for this process combination in Baden-Württemberg. The big advantage is that it has a broad effect.” He said it is effective for a wide range of pharmaceuticals, hormones and numerous other substances. Even germs can be removed from wastewater.

20 wastewater treatment plants have been equipped with the fourth treatment stage so far

With a view to prevention, Meinel explained further, the Ministry of the Environment began several years ago to support the expansion of wastewater treatment plants with innovative processes for the so-called fourth purification stage for the elimination of trace substances. In doing so, the state is concentrating on particularly sensitive bodies of water, as well as large wastewater treatment plants and pollution hotspots.

“On this basis, 20 wastewater treatment plants in Baden-Württemberg are now equipped with a targeted purification stage for the removal of trace substances, and another 23 with this special technology are under construction or in planning.”

– Helmfried Meinel, Ministerial Director

State contributes almost three million euros in Tübingen

The state is contributing almost three million euros to the total eligible costs in Tübingen of almost 13.8 million euros. “This is money well invested,” Meinel said. In addition to the city of Tübingen, the municipalities of Ammerbuch and Rottenburg are also financing the expansion.

The ministerial director also praised the fact that with the completion of the expansion and the commissioning of filtration in Tübingen, phosphorus elimination has now been raised to an even better level. “Aquatic animals and plants also benefit from this, because the ecological condition in the Neckar can be noticeably and sustainably improved.”

Flood victims receive tax aid

Published

on

The heavy rain and flooding not only claimed lives, but also caused enormous economic damage. To account for the material damage, the finance ministries of the states of North Rhine-Westphalia and Rhineland-Palatinate as well as the Bavarian State Tax Office have each enacted disaster decrees. Thomas Loibl from Ecovis in Landshut explains which tax support measures flood victims can receive.

 

What happens if my accounting records were destroyed by the water?

If accounting documents and other records have been destroyed or lost due to the storm, there are no adverse tax consequences to be drawn from this. Important: The affected taxpayer should document the destruction or loss in a timely manner and, to the extent possible, provide proof or credible evidence.

 

What can business owners do to mitigate the significant financial burdens?

The respective disaster decrees contain more than 20 tax support measures for taxpayers who are directly and not insignificantly affected – for private individuals as well as special regulations for entrepreneurs. Some examples from both:

Deferral and enforcement measures as well as adjustment of advance payments.
Note: Affected parties can submit the applications until October 31, 2021.

Deferral and remission applications for trade tax.
These applications must be submitted to the municipalities.

Special depreciation options for reconstruction
This allows expenses on a larger scale to be taken into account immediately to reduce taxes.

Special regulations for agriculture and forestry and income from renting and leasing
Farmers and landlords can take advantage of additional support measures.

Possibility to waive property tax
Interesting for all house and apartment owners.

Expenses for existentially necessary items (apartment, household goods, clothing) as extraordinary burdens

How are donations eligible?

The obligation to provide proof of donations has now been simplified. In addition, donation campaigns can also be organized by non-profit corporations that, according to their articles of association, do not promote charitable purposes, for example, or are regionally bound.

Furthermore, so-called donations from wages and salaries are possible. In this case, an employee waives payment of part of his or her salary. The employer pays this amount into a donation account of an institution entitled to receive donations. The donated portion of the salary is then not taken into account as wages. No payroll tax or social security must be paid. “However, the employer must fulfill and document the use requirement. Important: The donated salary must be recorded in the payroll account,” says tax consultant Thomas Loibl.

Tip: Even expenses for existentially necessary items (apartment, household goods, clothing) can be taken into account for tax purposes. In exceptional cases, these can be deducted as extraordinary expenses.
