TECHNICAL PRINCIPLE

Modern indoor climate control takes no air-conditioning

and is even more efficient, sustainable and comfortable

What are the requirements an indoor climate shall meet today?

  • High energy efficiency, which ensures ecological sustainability – especially when using carbon-neutral sources of energy – which is not only modern, but also subject to funding in many countries.
  • Operating costs, i.e. expenditure on energy consumption and maintenance shall be reduced or kept as low as possible, since prices of energy sources are continuously growing.
  • Solutions of climate control shall keep the indoor climate within a stable and comfortable temperature range at all times – notwithstanding climate zones and weather.
  • An indoor climate should be neither too dry nor too wet, as both would pose risks to health.
  • Wet walls, mainly caused by condensation of moisture from cold air, are a breeding ground for mould and must be avoided in any case.
  • Air should circulate naturally, cause no draft, be unpolluted and free of germs.

These requirements can only be met, if the most efficient solutions are chosen to transport, distribute and release energy. EcoSyst climate panels fulfil all requirements of a modern indoor climate – being health-promoting, environmentally friendly and cost-effective.

EcoSyst relies on the technology of capillary tube mats and has taken it to perfection.

EcoSyst even enables cooling below the dew point without accumulating condensate!

Learn more about the underlying physical principles:

One litre of water can hold and transport the same amount of energy as 3m³ (i.e. 3,000 litres!) of air do. Therefore, climate control by means of air requires to warm up or cool down and dehumidify gigantic amounts of air, which then need to be pushed by powerful fans/blowers through large pipe systems to their destination.

If, however, water is used as a medium, transport of the required energy can be accomplished by efficient and silently running pumps.

Nature can serve as a model of optimal energy distribution. A cardiovascular system e.g. would distribute energy from the heart (resembling the pump) through the aorta, arteries, arterioles down to the capillaries, thus providing (almost) identical temperatures in all parts of the body.

The technology of capillary tubes follows this principle, ensuring an even distribution of energy across all areas. Huge temperature differences as would be common when conditioning air as a medium of climate control, will therefore be avoided.

A modern system of heating and/or cooling shall first of all use the advantages of radiant energy and secondly be able to react quickly without long start-up periods.

For wellbeing the effect of radiant energy matters more than the air temperature in a room does. In winter the indoor climate will feel uncomfortable even at an air temperature of 22 °C, if walls are very cold. However, if a room’s surfaces (walls, ceiling, floor) are warm, the indoor temperature can be lowered to 18-19 °C without any loss in wellbeing.

In order to cool down or heat up a room quickly, energy shall be released close to surfaces, ideally from under the plaster. Systems that are installed more deeply, i.e. embedded in the concrete of walls or floors, are inert and even keep releasing energy when the user no longer needs it.

Systems of heating and cooling based on the technology of capillary tubes have been in use for more than 25 years. Lists of projects equipped by manufacturers of capillary tube mats include first-class addresses that evidently prove the efficiency of this modern technology: the Olympic village in Vancouver, the German federal parliament, hotels, villas, department stores, and company headquarters.

The efficiency is due to the low inlet temperature of water required to create the desired indoor climate. Thanks to the large surface available to release energy, rooms can be heated and cooled using water of 28–30 °C and 22–24 °C, respectively. It is no problem to generate these temperatures by means of renewable energies, which allows for a carbon-neutral climate control at almost any location.

However, by now the use of this technology is limited to regions of moderate climate. The reason for this is a problem related to the so called “dew point.” In southern countries with hot days in summer a comfortable indoor climate can often be ensured only by massive cooling – namely at temperatures below the dew point. If air temperatures fall below the dew point, moisture in the air will condense on the cooling surface, which results in water dripping from the ceiling or running down the walls.

After several years of research and development, funded by the government, the EcoSyst climate panel is now available to the market as an innovation to solve the problem arising from condensate and allows for massive cooling below the dew point.
