About Cold Ceilings

Air conditioning of your premises with radiant cold ceiling.

Radiant cold ceiling is an innovative technology that uses chilled water running through ceiling panels to absorb heat and cool a room. It operates silently, is energy-efficient, and provides precise temperature control. This new technology offers significant advantages over traditional air conditioning systems and is becoming increasingly popular in homes and businesses worldwide.

How does it work?

Radiant cold ceiling systems use chilled water running through pipes embedded in the ceiling panels to absorb heat and cool a room. The process of cooling is known as radiant cooling and works by absorbing the heat that radiates from the occupants and objects in the room.

The chilled water in the pipes is typically maintained at a temperature of around 16°C to 18°C (60°F to 64°F). As the warm air in the room comes into contact with the chilled ceiling panels, the heat is absorbed by the cool water running through the pipes. This absorption of heat causes the water temperature to rise slightly, and the warmer water is then sent back to the chiller, where it is cooled again and recirculated through the ceiling panels.

As the ceiling panels cool the room, the occupants’ bodies and objects in the room emit heat, which is absorbed by the ceiling panels. This process of absorption and emission continues, creating a comfortable and even temperature throughout the room.

The closed water cycle of the system enables its use with either gas or water chillers. You may use existing chiller unit from your traditional AC unit. The system is composed of several basic components, similar to those found in traditional radiator or underfloor heating systems:

Capillary tube cooling mats
Distribution unit (manifold, pump, pressure expansion tank)
Chiller
Heat exchanger (water to water or gas to water)
Room temperature control

Quick Benefits compare to regular AC systems.

No Air Movement

Unlike traditional AC systems, radiant cooling systems do not blow air, which means that there is no air movement at all. This can benefit those who dislike drafts or have sensitivities to airborne particles. Finally, the lack of air movement reduces the risk of catching a cold, making radiant cooling a healthier and more comfortable alternative to traditional AC systems.

Healthy Environment

Radiant cooling can contribute to improved indoor air quality by reducing the circulation of airborne pollutants, allergens, and other contaminants, including viruses and bacteria that can be harmful to health and cause stink. It maintains a comfortable and consistent indoor temperature without the need for forced air circulation, reducing the risk of respiratory problems such as asthma.

Noise Reduction

Radiant cooling systems are quieter than traditional AC systems because they don’t use noisy fans or other equipment. Instead, they use a combination of radiation and convection to transfer heat. This is particularly beneficial in environments where noise pollution can be disruptive, such as schools, hospitals, or residential settings where improved sleep quality is desired.

Sustainable and Efficient

Radiant cooling systems are a sustainable and energy-efficient alternative to traditional AC systems. They use 30% less energy because they don’t rely on forced air circulation to cool the room, resulting in lower energy bills and reduced greenhouse gas emissions. By reducing energy consumption radiant cooling systems can help reduce the carbon footprint of buildings.

Maintenance-free

Unlike traditional AC systems, which require regular filter changes, duct cleaning, and other maintenance tasks to keep them operating efficiently, radiant cooling systems can operate for long periods without any maintenance. This not only saves time and money on maintenance costs but also reduces the risk of system breakdowns or failures ensuring uninterrupted comfort.

No Water Drain

Regular AC systems generate a significant amount of condensed water that must be drained away. Radiant cooling systems don’t produce any condensed water, because they operate at higher cooling temperatures, which reduces the risk of condensation. As a result, there’s no need for complex drainage systems or regular maintenance of drain pipes, which can become clogged.

Space Saving

Traditional AC systems require large ductwork and bulky air handlers to distribute air throughout the room, which can take up significant space in the ceiling. In contrast, cold ceiling systems use thin profile ceiling panels to distribute cool air, for a more space-saving design. This can be beneficial for limited ceiling height or where the aesthetics of the space are a concern.

Sleek Design

Radiant cooling systems offer greater design flexibility compared to traditional AC systems because they don’t require bulky ventilation grills and unit maintains hatches to be installed on walls or ceilings. Instead, the cooling panels or pipes are integrated into the ceiling or walls, creating a sleek and unobtrusive design that blends seamlessly with the building’s architecture.

How does it look?

Capillary mats covered with plaster

One of the key benefits of these systems is that they can be easily integrated into various ceiling designs, including arch ceilings, without spoiling the overall aesthetic. The small diameter tubes used in the system also allow for a higher degree of flexibility when it comes to the placement of the cooling system. This means that architects and designers can create more customized and innovative indoor spaces without having to compromise on comfort.

Overall, cold ceilings made of capillary tube mats offer a unique cooling solution that is perfect for modern and minimalist design aesthetics. Their small ceiling profile and energy efficiency make them an ideal choice for those who are looking to create a comfortable, sustainable, and visually appealing indoor environment.

Drywall (Plasterboard) prefabricated panels

The heat-conducting pipes in standard thermally activated drywall ceilings consist of BEKA capillary tube mats, which are located on the back of the drywall panels for good thermal conductivity and hydraulic connection in the ceiling cavity.

Our company also offers ready-to-build plasterboard with integrated capillary tubes or integrated 10 mm PE-RT tubes. We provide drywall panels with capillary tube mats and polystyrene insulation in standard dimensions as part of our prefabricated elements.

Additional insulation material can be added to the heat-carrying capillary tubes in the standard construction to improve the reaction speed of the ceiling heating and cooling.

Metal Cassette Ceiling with Capillary Tube Mats

We offers a solution that combines metal cassettes or ceiling panels with capillary tube technology for improved energy efficiency. The capillary tube mats, with a diameter of 3.35 mm and wall thickness of 0.5 mm, are spaced 10 mm apart, compensating for the low thermal conductivity of polypropylene and ensuring an even surface temperature. The mats can be inserted with millimeter precision into almost any format of the ceiling cassette, maximizing the thermally active surface of the ceiling.

Gluing the capillary tubes in the cassette is an advantage, but it must remain flexible to avoid reducing heat transfer from the cassette surface to the heat-conducting pipes. BEKA offers capillary tube mats manufactured with millimeter precision for the corresponding cassette format, which can be glued into the ceiling cassettes upon customer request, reducing sorting work on the construction site. Alternatively, the capillary tube mats can also be inserted into the ceiling cassettes on site by the construction team, which is especially useful for modernization projects.

Finally, the capillary tube mats are quickly and securely connected to each other and to the supply pipelines using flexible hoses and plug connector technology. The supply pipelines can also be prefabricated from polypropylene tubing with inserted plug-in couplings, simplifying the installation process even further. Overall, BEKA’s capillary tube technology provides a flexible and efficient option for heating and cooling in combination with metal cassettes or ceiling panels.
