Infrared hall heating in your production: How to create the right indoor climate for your production

Hall buildings are a world of their own. Particularly in winter, their high ceilings pose a real challenge for anyone who wants to ensure the most pleasant working environment possible in the workplace. But there are solutions - for example, infraredHall heating. But first you should ask yourself: What does a pleasant indoor climate actually mean? And which factors are decisive for this? There are various explanations that basically boil down to four different factors, which we will explain to you in this guide.

4 factors that influence a pleasant indoor climate at the workplace

Basically, when it comes to a pleasant indoor climate in the workplace, you should always pay attention to these four factors:

While the temperature is highly dependent on the type of activity (18 °C is sufficient for physical work, at least 20 °C is required when sitting), there is a consensus on the factors of humidity, air movement and air quality. 40 - 60 % humidity, air movement of no more than 0.15 m/s (at 21 °C) and an oxygen content of 21 % are guideline values that most people find pleasant and therefore constitute the optimum indoor climate at the workplace.

The right indoor climate at the workplace influences the productivity of your employees

Dass sich ein schlechtes Raumklima am Arbeitsplatz negativ auf die Leistungsbereitschaft und -fähigkeit Ihrer Mitarbeiter auswirkt, ist erwiesen. Sie merken es spätestens, wenn Beschwerden eingehen oder der Krankenstand ansteigt. Neben vielen anderen Stellen hat sich die Bundesanstalt für Arbeitsschutz und Arbeitsmedizin (baua) damit beschäftigt und schreibt dazu in einem Bericht:

"Minor deviations from the "optimum climate" initially lead to discomfort, resulting in complaints about the climate (too hot, too cold, draughts). If these effects intensify and climate monotony or the inability to influence the climate yourself is added to this, this can lead to a high level of dissatisfaction, stress and psychological strain; motivation and satisfaction with one's own work decrease. Ultimately, the willingness to make an effort decreases, employees feel less productive and objectively measurable productivity losses and increased error rates can occur." 

The problems you encounter when you want to create the optimum indoor climate in the workplace

Hall buildings are not easy to heat. Because the rooms are particularly large and high, it can also be particularly challenging to achieve the ideal indoor climate in the workplace. Find out below what problems arise when choosing a hall heating system.

Problem 1: The size of hall buildings as the biggest challenge for the indoor climate in the workplace

It is still relatively easy to positively influence the indoor climate in offices. However, if the workplace is a production hall, those responsible face completely different challenges. This is because the corporate goal of a "good working environment" faces headwinds from various directions:

Creating the optimum indoor climate in the workplace is therefore anything but easy in a production hall. Just keeping the temperature in such a building at a comfortable level is no trivial matter. Particularly because good and even heating is also important against the background of the Energy efficiency must be considered. Not to mention humidity, air movement and air quality.

Problem 2: Not every heating system contributes to a good indoor climate at the workplace

To the Hall heating werden die unterschiedlichsten Technologien genutzt. Nicht immer mit dem gewünschten Ergebnis was Funktionalität, Wärmekomfort und Wirtschaftlichkeit betrifft. Sie unterscheiden sich nach Art des Energieträgers (Heizöl, Gas, Holz, Strom, Sonne) und nach Art der Bereitstellung: zentral oder dezentral. Dezentral beheizte Systeme sind heute in vielen Anwendungsbereichen die Technologie der Wahl. Dabei nehmen insbesondere gasbetriebene Infrarot-Hallenheizungen des Typs Dunkelstrahler eine herausragende Rolle ein, weil sie speziell für die Beheizung hoher Räume zugeschnitten sind und dort wichtige Vorteile bieten. Vorteile, die auch die neue Generation Infrarot-Hallenheizungen der neuen Fair.AIdH*-Technologie bieten. Nur dass diese zusätzlich effektiv als 2in1-System mit integrierter LED-Hallenbeleuchtung eingesetzt werden können und – noch wichtiger – energieflexibel und regenerativ mit Strom oder Wasserstoff betreibbar sind.

* Fair.AIdH* steht für die neue energieflexible Heizungstechnologie zur Dekarbonisierung von Hallengebäuden. Die Abkürzung bedeutet: Energy Flexible, adaptive, infrared, AI driven Hall Heating.

No hot air: Why infrared indoor heaters are so good for the indoor climate in the workplace

Infrared hall heaters are Radiant heaters. These heating systems transfer heat by emitting infrared radiation. As soon as the rays hit bodies or objects, they are converted into heat. The effect of infrared hall heaters is therefore similar to the heat principle of the sun, which does not heat the air but directly heats people, room frames, machines and other objects in the hall, resulting in a particularly pleasant indoor climate in the workplace.

Radiant heaters also have the decisive advantage in high rooms: where no air is heated, no warm air can rise high under the hall roof and form unused warm air cushions there - outside the working area. Infrared hall heaters are specially designed to bring heat evenly into the area of use. And nowhere else. Incidentally, this is also the key reason why these systems are so energy-saving and therefore so economical and environmentally friendly.

Infrared indoor heaters influence an optimal indoor climate in the workplace in many different ways

Die gleichmäßige gezielte Temperaturführung ist nicht der einzige Grund, warum Infrarot-Hallenheizungen für ein angenehmes Raumklima am Arbeitsplatz sorgen. Dadurch, dass keine Warmluft entsteht, verursachen diese Systeme keine unangenehmen Zugerscheinungen – und wo keine Zugluft ist, gibt es keine Staubaufwirbelungen, die die Luftqualität belasten könnten. Staub ist fast überall – daher ist dies ein wichtiger Pluspunkt für das Wohlgefühl und die Gesundheit Ihrer Mitarbeiter ebenso wie für den Schutz Ihrer Produktionsmaschinen. Ein Vorteil für die Luftqualität ist auch die geschlossene Verbrennung des besonderen Typs Infrarot-Hallenheizung – und damit verbunden ihre Eigenschaft, dass Abluft gezielt nach außen abgeführt wird und nicht im Hallengebäude verbleibt. So lässt sich diese Waste heat incidentally - increasing efficiency - for other thermal processes, e.g. for hot water preparation (keyword: hybrid systems).

How to specifically control a good indoor climate at the workplace with an infrared indoor heating system

Infrarot-Hallenheizungen wie die Technologien von KÜBLER sind heute nur noch selten einfache Stand-alone-Lösungen. Sie sind digital in Systeme eingebunden, die eine Vielzahl smarter Funktionen ermöglichen. So lassen sich in den Hallen verschiedene Nutzungsbereiche definieren, gezielt ansteuern und bedarfsgerecht temperieren (Stichwort: Zonenbeheizung). Intelligente Effizienzmodule erkennen z. B. offene Hallentore und schalten die Heizung automatisch ab, bis die Tore wieder geschlossen werden. Je nach Länge der Toröffnungszeiten lassen sich so nennenswerte Energieeinsparungen erzielen. Ein- und Abschaltzeiten werden heute digital optimiert und gesamte Heizprozesse im Monitoring überwacht und für Audits z. B. nach DIN EN ISO 50001 analysiert. Ebenso lässt sich auch die Luftfeuchtigkeit regeln – das ist sinnvoll, wenn Sie z. B. korrosionsempfindliche Waren wie Coils lagern.

The right waste heat recovery for your business - how to convert waste heat into energy in just a few steps

Only around half of German companies know how waste heat recovery works properly and what potential it holds - according to the dena in their Publication on waste heat recovery as part of the Initiative Energy efficiency. This means that an estimated 226 TWh of usable heat goes unused every year. That is 36 % of the energy used by the entire manufacturing industry. Clearly, this costs companies an enormous amount of money, but at the same time the unused waste heat has a negative impact on the environment. Around 60 million tons of the greenhouse gas CO2 are unnecessarily evaporated into the atmosphere every year. In view of rising energy costs and climate protection targets, companies simply can no longer afford to do this.

How can you benefit from intelligent waste heat recovery? Find out in this article.

Start your smart waste heat utilization by identifying waste heat sources

Depending on the type of operation, waste heat is generated in a wide variety of places. Ovens, machines, cooling systems and uninsulated pipes of hot air heating systems are probably the classics. Get to the bottom of the causes of wasted waste heat by thoroughly analyzing and evaluating energy consumption throughout the company. The next step is to avoid or at least reduce unnecessary waste heat by optimizing processes. The following questions will help you do this:

With a comprehensive analysis, you can already save a lot of waste heat. For the rest, you should rely on intelligent waste heat recovery.

Industrial waste heat recovery - simply pass on the waste heat

The practical thing about intelligent waste heat utilization is that you can use waste heat in a variety of ways to increase energy efficiency in your company. For example, if you don't want to use the waste heat from your company yourself, others will be happy to do so. For example, district heating networks that cover the heating requirements of private households or public buildings, or even neighboring companies. Of course, the necessary infrastructure must be in place or created for this - on the other hand, a certain amount of heat loss during transportation must be taken into account.

The correct use of waste heat is also important for cooling

Do you have enough heat, but would you like a little more cooling and electricity? Then it's best to use waste heat for exactly that. With chillers, steam processes and ORC systems, waste heat can also be used to generate cooling or electricity - so the right use of waste heat can also bring you benefits in summer.

... and is also ideal for other processes

"Hybrid heating" is an important keyword here. This is because the correct use of waste heat can also play an important role in the preparation of hot water or the heating of rooms. While this variant of waste heat utilization has already established itself in many private households, it is now also suitable for heating hall buildings. This is because, thanks to inefficient technology and a lack of insulation, they have a reputation for consuming a lot of energy.

Numerous heat flows in the building, such as process heat or waste heat from compressors, can be harnessed if you integrate them into infrared heating systems that have been combined with a residual heat utilization system. You can even integrate renewable energies such as solar thermal energy to efficiently support heat generation in your company. In this way, you benefit from the clever use of waste heat in many essential processes in your company.

The bottom line: the right use of waste heat and hybrid heating are worthwhile - especially from a financial perspective

Anyone who integrates intelligent waste heat recovery in their company and therefore has to use less energy to generate heat saves money. That is crystal clear. How this translates into concrete figures depends on various factors, such as

At a production plant in Rhineland-Palatinate, for example, the recovered energy completely covers the heating requirements of the 1,200 m² of office space. Another company saved with efficient waste heat utilization 9,000 euros per year - and some drinking water that was previously drained off almost unused.

The Federal Ministry for Economic Affairs and Energy is also concerned about the efficient use of waste heat in view of the figures mentioned above. Entrepreneurs can therefore not only save energy costs with greater energy efficiency, but can also benefit from funding programs. The "Federal funding for energy efficiency in the economy" package offers several options for this.

Conclusion: Optimization potential in waste heat recovery can be found in a wide variety of places

Hall modernization, proper insulation, highly efficient Heating systems and waste heat recovery: there are many ways to increase the energy efficiency of your business and reduce costs. Feel free to contact us and let us advise you on the optimal use of waste heat. We can help you find out how you can use the previously "wasted" waste heat from your processes to good effect. We look forward to hearing from you and accompanying you on the path to optimal waste heat utilization.

How to heat offices with machine waste heat almost free of charge

Almost all machines produce waste heat. Compressed air systems or curing ovens are at the forefront here, as they generate the most heat. However, this usually dissipates unregulated in the building, which is not only annoying, but also a wasted option for reducing your heating costs. In this article, you can find out all about how you can cleverly use the waste heat from your production machines to heat various rooms, such as offices, and thus reduce your heating costs and also do something good for the environment.

Heat offices with the waste heat from your machines

All manufacturing and production processes rely on machines that usually generate a lot of waste heat, which you can use with the help of modern technologies to heat your offices and other premises. However, machines such as curing ovens are not the only ones that give off valuable heat. Other technologies or building heating systems also have significant potential for warm exhaust air that you should use to heat offices, for example.

Heat offices cleverly - stop waste heat going to waste

In most cases, the valuable waste heat from your machines and building heating systems is wasted in the building without being regulated, which is annoying. On the one hand for the environment, but above all for business management. This is because a lot of energy is wasted in this way, which has to be paid for expensively elsewhere, for example to heat the canteen or the office. But does this now mean that every single machine or Heating must be elaborately equipped with its own residual heat utilization?

Equip machines to heat offices with waste heat

For many commercial enterprises and companies, this question is more economically relevant than initially assumed. Technologies such as integrated heat exchangers can be an interesting approach here. They are designed to combine different heat flows and make maximum use of them in the company, thus heating rooms such as offices. The investment costs are so low that they do not really outweigh the savings. Depending on the system, offices or entire office areas can be heated in this way. One example is a medium-sized production company in North Rhine-Westphalia, where energy consumption has been reduced so significantly that the management can look forward to around 46,000 euros more cash in the till every year.

Conclusion: Waste heat is the smartest way to heat your offices

The waste heat from your production machines is valuable - don't just let it go to waste. An ideal way to use waste heat intelligently is to use it to heat your offices, for example. But of course you can also reuse the waste heat from your machines in other ways. Find out exactly how here.
