CONCRETCOOL

Product catalog summary

Introduction to CONCRETCOOL
CONCRETCOOL is an innovative system that enhances air handling units (AHU) by integrating concrete activation with air. This system uses supply air as the operating medium, eliminating the need for water in concrete ceilings. It provides cooling by utilizing the natural cooling potential of outside air, particularly effective during night-time.

Specifications and Functionality
The system employs aluminium cooling pipes (Ø 60 mm and Ø 80 mm) embedded in concrete ceilings. These pipes, with finned interiors for improved heat transfer, allow supply air to flow through them, cooling the ceiling and heating the air to the ceiling's temperature. This process is self-regulating, requiring no primary energy, and achieves a supply air outlet temperature of approximately 21°C without additional heaters.

Efficiency and Environmental Impact
CONCRETCOOL significantly enhances the heat recovery of AHU systems to over 95%, surpassing the requirements of the Renewable Energies Heat Act. It offers substantial energy savings, potentially reducing operating costs by up to 50% and achieving passive house standards with minimal energy consumption.

Applications and Benefits
Since its market introduction in 2000, CONCRETCOOL has been installed in over 76 projects, covering more than 335,000 m² in various buildings such as offices, libraries, schools, and clinics. The system is particularly valued for its ability to provide cooling without water, offering flexibility, reduced building costs, and optimal thermal comfort.

System Advantages
Key advantages include energy savings, modular distribution of cooling pipes, reduced building costs due to lower floor heights, and a high degree of heat recovery. The system also minimizes the need for complex control systems.

Additional Services
Kiefer offers a range of services, including system suggestions, cooling load assessments, and building simulations. They provide comprehensive support from planning to commissioning for AHU systems.

Innovation CONCRETCOOL What is CONCRETCOOL? CONCRETCOOL is the enlargement of an air handling unit (AHU) with the additional component of concrete activation with air. Supply air acts as the operating medium. The air flow rates required for hygienic purposes also meet the cooling needs of the building. Additional nighttime cooling provides enhanced cooling capacity during hot weather periods. Therefore, there is no need to use water in concrete ceilings! Why CONCRETCOOL? Cooling pipe Ø 60 and Ø 80 mm Depending on the location of your construction project, different meteorological conditions...

Function CONCRETCOOL Cooling pipes are laid in the structurally neutral zone. How does CONCRETCOOL work? Cooling pipes Ø 60 mm and Ø 80 mm made of aluminium, which is an excellent thermal conductor, are cast into the concrete ceilings in line with the grid. The inside surface of the pipes is finned to improve the transfer of heat. therefore not required. The process is self-regulating and operates virtually without fluctuations with a high degree of temperature stability due to the significant storage capacity of the concrete ceilings. The heat recovery of the AHU system is increased to over...

System Benefits CONCRETCOOL Ceiling cooling with air Architects and building owners welcome the ability to dispense with water for construction part activation, particularly in highly technical buildings. However, many of them are only familiar with water-borne systems and raise the following questions: Why use air for cooling? The meteorological annual data for outside air (8-11 °C) offers significant cooling potential free of charge. This cooling potential can meet the cooling requirements of a building! How much air is required? We recommend that the air flow rate be calculated on the basis...
