Wasserkabel system

The Wasserkabel one system technology for heating and cooling uses water capillary mats that are made from polypropylene – a high quality, environmentally friendly and safe plastic with excellent thermal management and elasticity properties. Polypropylene has considerable advantages over commonly used materials like copper and aluminium:

  • Resistant against corrosionwk
  • Low weight (9 times lighter than iron)
  • Can be welded easily
  • Low wall friction losses
  • Minimal flow noises
  • Suitable for high compression loads
  • Good thermal insulation properties (I=0.21 W/mK)5
  • High resistance against aggressive substances
  • Optimum of hygiene
  • No tension cracking
  • Non-conducting
  • Very good heat ageing resistance
  • 100% recyclable; combustion without environmentally hazardous substances

Water capillary mats system

The water capillary mats system includes capillary mats, actuators, connecting pipes, fittings, system performance measurement and control devices, the heat exchanger (if necessary), the boiler and/or cooling system.

  • The system is individually adaptable and fast switching.
  • Quickly responds to the required changes in temperature – max within 9 min.
  • Circulates water under a 2–3 bar pressure, the system needs to be filled only once.
  • Applicable for both cooling + humidity reduction or/and heating, a single system is possible for both heating and cooling.
  • The water capillary mats system for cooling + humidity reduction can be connected to the cooling system based on the principle of solar energy absorption that provides excellent energy efficiency of the system.
  • The water capillary mats system can be connected to natural sources of energy, such as river, lake, sea, etc. that provides excellent energy efficiency of the system.

Operation of the water capillary mats system

The water capillary mats system can be connected to different heat transmitters:heat_sources

North Germany from end of September until April. Heat pump efficiency indicators of thermal energy production, which varies depending on the outdoor temperature and supply flow temperature.


Heat in physics

Heat in physics is thermal energy transfer between two bodies of different temperatures.

Heat flows between regions, which are not in thermal equilibrium – from regions of higher temperature to places of lower temperature to equalize the temperature.

Heat transfer takes place in space in three different ways:heat

  • Thermal conduction is the transfer of heat by microscopic collisions of particles and movement of electrons within a body.

Fluid and thermal conductivity of individual gases is negligible, while the thermal conductivity of a solid body is changing in very wide range. Thermal conduction was originally called Diffusion.

  • Convection is the movement of groups of molecules within fluids such as liquids or gases.

For example, the heating radiator warms up the room’s air in contact with it. Cold air displacing the warm air in the room, moving it to the top. In this way the heat in the air is transferred from the radiator to the other room locations.

  • Thermal radiation is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero.

Electromagnetic waves from the body surface is spreading in all directions. Faced with other bodies, part of the radiation energy is absorbed, turning into a thermal energy again (increasing body temperature).

Project “Production Facility of Capillary Tube Mats in Latvia”
JSC “Wasserkabel Baltic” since August 2015 implements project “Production Facility of Capillary Tube Mats in Latvia”. Project in accordance to contract signed on August 17, 2015, with Investment and Development Agency of Latvian and Ministry of Economics of Republic of Latvia is funded by Norway Grants in support program “Green Industry Innovation”.
Within the framework of project JSC “Wasserkabel Baltic” plans to establish a new and innovative capillary tube manufacturing plant with energy efficient heating/cooling system featuring wide application and significant contribution in reducing energy consumption and related environment pollution as well as heating/cooling costs.
Delivery and installation of equipment as well as knowledge transfer activities in cooperation with the Norwegian University of Science and Technology and publicity events are planned in the project.
Project “Production Facility of Capillary Tube Mats in Latvia”, id. No. NOFI/LV06/AK2/14, contract No. NP-2015/24, is implemented using EUR 509’104 cofinancing from Island, Lichtenstein and Norwegian through Norwegian Financial Mechanism.
