CAPILLARY TUBE MATS
HEATING& COOLING APPLICATION

SINOLANC radiant ceiling system can not only be used for cooling, but also for energy-efficient heating. The implementation of ceiling heating and cooling in one system reduces operating costs.

Capillary tube mats can be installed either in or on the ceiling constructions. Due to the small outer diameter of the capillary tubes and their high degree of flexibility, capillary tube mats can also be plastered directly onto the bare concrete ceiling. Even the vaulted and curved ceiling structures is possible with capillary tube technology.

Heating capillary tube mats installed close to the ceiling surface, this minimizes the thermal resistance from the heating water to the thermally activated surface. It can be operated with low supply temperature, which are only slightly above the room temperature. The result is high energy efficiency.

SINOLANC RADIANT CEILING
HEATING & COOLING

Cooling radiant ceilings provide a high level of acceptance and satisfaction among users. In summer, the ceiling cooling supplies a uniform temperature reduction without the disruptive effects of air conditioning such as cold air circulation and annoying noise.

For cooling purposes, SINOLANC Capillary Tube Mats are preferentially installed either in or on the ceiling; in this case the surface temperature of the ceiling is, depending on the supply temperature, approx. 19 °C at only 2 to 3 K spreading between supply and return (supply temperature = usually 16 °C; return temperature = 18 °C or 19 °C). Depending on the type of ceiling or the way the capillary tube mats are installed, cooling capacities of up to 100 W/m² (Δ=10 K) can be achieved for closed radiant cooling ceilings.

FEATURES

• Heating and cooling with one system

• Low installation height

• Even heat distribution

• Directly perceptible radiant heating

• Low air circulation, healthy indoor climate

• Silent system without annoying radiators

• Low energy cost

Sinolanc capillary tube mats with plaster ceilings are popular because of their simple appearance and installation. The capillary tube mats are plastered directly underneath a concrete ceiling, which invisibly integrated into the ceiling not only provide excellent cooling in the summer, but can also be used to heat comfortably and energy-efficient. The renovation of plaster ceilings does not require much effort.

A complete embedding of the capillary tubes is achieved with a spraying plaster layer thickness of 10-15 mm. Mat distributor pipes and supply lines are accommodated in the a slot or void of the ceilings. A large-area and even heat conduction is achieved.

Due to the ceiling construction is thinner than 15mm, the heat exchange between the mats and the plaster surface is intensive to ensures a rapidly heat-up or cool-down. The water circulates noiselessly in the capillary tube mats and regulates the room temperature largely by radiation, partly by convection. The plaster cooling ceilings achieve impressively high heating and cooling capacities.

PREFABRICATED RADIANT GYPSUM INSULATION PANEL WITH AN INTEGRATED CAPILLARY TUBE MATS

The capillary tube mats are embedded within prefabricated gypsum boards, aluminum foil insulation panels, or metal plates, or adhered to their surfaces to ensure uniform heat transfer.

The capillary tube mats are connected to the supply and return water system via main pipes and linked to the entire system using flexible hoses or specialized pipe connectors, ensuring smooth fluid circulation.

The prefabricated radiant panels with integrated capillary tube mats can be directly installed on walls, ceilings, or floors. They are fixed using specialized adhesives, screws, or keel structures. The aluminum foil layer enhances thermal radiation efficiency, while the gypsum board itself provides a certain level of insulation. This modular installation is quick and convenient which is suitable for flat ceiling application.

Sinolanc capillary tube mats ceiling system offers an efficient and quick install solution for heating and cooling in drywall applications. By integrating lightweight capillary tube mats directly into a suspended ceiling structure on the top side of the plasterboard, this system delivers comfortable, uniform temperature control with minimal heat loss.

Ceiling Cooling or Heating In Drywall /Plasterboard Installation:
1. Substructure Installation： Prepare and Install the Metal Framework: Secure an aluminum or steel framework to the ceiling as a substructure to support the plasterboard. Leave a gap of about 100 mm between the support profile and the wall connection profile. This gap allows space for inserting the capillary tube mats and connecting supply and return pipes.

2. Supply and Return Pipe Layout
1. Pre-lay the main supply and return pipes in the ceiling void to ensure smooth water flow for uniform heating and cooling.
2. Connect the mat distributor pipes of the capillary tube mats in accordance with the dimensions of the substructure by means of heating element socket welding.

3. Capillary Tube Mat Installation
1. Place the mat distributor pipes of the rolled‐up capillary tube mats on the metal framework in the ceiling void and loosely fixed the mat distributor pipes to the basic profiles with cable ties. Ensure sufficient space for welding connections.
2. Use heating element socket welding to connect the mat distributor pipes to the supply and return lines.
3. Secure the mats using retaining clips between the support profiles. Ensure the open side of the capillary tube mats faces the drywall panels.
4. Openings for lamps and ventilation grilles are possible up to a diameter of approx. 100 mm by pulling the capillary tubes apart.

4. Insulation Installation
1. Apply insulation material (such as mineral wool or polyurethane) between the support profiles to minimize heat loss and enhance efficiency.
2. The insulation should slightly press the capillary mats against the drywall to ensure optimal heat transfer.

5. Drywall Panels Installation
1. Secure drywall panels to the metal framework using self-tapping screws, ensuring proper alignment and avoiding damage to the capillary mats.
2. Any type of drywall panels can be used - whether metal, unperforated or perforated ceiling.

6. System Testing and Finishing
1. Perform an initial air pressure test to check for leaks, followed by a liquid medium test in accordance with industry guidelines. Test at 1.5 times the working pressure for a duration of at least 20 minutes to check for leaks.
2. Keep the system under test pressure throughout the remaining installation process.
3. Once testing is successful, seal drywall joints, apply finishing, and complete painting.

Drywall Plasterboard ceilings

Preparation of the Ceiling Structure
1. Install a suspended gypsum board ceiling with sufficient void space to accommodate distributor pipes and supply lines.
2. Ensure the ceiling structure can support the additional weight of the capillary tube mats and the plaster layer.

Positioning the Capillary Tube Mats
1. Mount the supply and return lines for capillary tube mats in the ceiling void, leaving enough space for connections.
2. Secure the two mat distributor pipes of the rolled-up capillary tube mat to the substructure profiles using stainless steel clips or galvanized staples, then connect them to the supply and return lines.
3. Guide the capillary tube mats through a pre-cut slot in the gypsum board panel to the room side.
4. Weld the capillary tube mats together to form a closed hydraulic circuit. Ensure all connections are secure and leak-proof.

System Testing：Perform a leak test at 10 bar, keeping the system filled with water throughout the installation to detect potential damage.

Applying the Plaster Gypsum Board Panels
1. Close the ceiling structure with standard gypsum board panels, fixing them edge to edge
2. Apply a primer coat evenly within 48 hours before plastering to to enhance adhesion.

Securing the Capillary Tube Mats and Plastering
1. Roll out the capillary tube mats and attach them tightly to the underside of the gypsum board over the entire surface and fasten them using stainless steel or galvanized staples.
2. Apply a 10-15 mm plaster layer using professional techniques, ensuring even coverage.
3. Ensure the plastered surface is properly separated from adjacent building components to prevent cracks due to thermal expansion. Allow the plaster to dry and cure properly before proceeding with final ceiling finishes.

Final Inspection and Commissioning
1. Conduct a pressure test to verify the integrity of the hydraulic system.
2. Inspect the installation to ensure proper attachment and finishing.
3. Once confirmed, complete the ceiling construction and proceed with system commissioning.

DEW POINT IN COOLING MODE

Surface cooling systems bear the risk of dew point exceedance and of condensation on the cold surface. This risk can be safely ruled out! Therefore each control zone is equipped with one or several dew point sensors. To avoid condensation on the cooling surface, in case of a dew point risk the flow through the capillary tube mats is stopped by closing the control valve. Switching off the individual zones can be counteracted by using an enthalpy-based supply temperature control.

In large and intensively used office buildings cooling ceilings are often combined with a supporting ventilation system, so that dew point exceedance happens very rarely. This is necessary as a rule in order to provide all users with the required fresh air as well as to remove the bad air. The relative humidity is controlled by ventilation and maintained at a comfortable and within dew point non-critical range.

For this reason, cooling ceiling technology has been popular used in large office and administration buildings successfully for many years

SINOLANC WALL RADIANT
HEATING & COOLING

Sinolanc capillary tube mats can be integrated into walls of various designs and used as wall heating and wall cooling. The flexibility of the capillary mats allows them to be installed to all the available conditions. The radiant wall capillary mats are generally carried out using the plaster method or drywall.

Wall heating systems for plastering processes are the classic among radiant wall heating. The capillary tube mats are fixed directly to a wall (gypsum board, brickwork, concrete) with a load-bearing substrate and plastered in. All commercially available plasters such as gypsum, lime, cement or acoustic plaster are suitable. Thin plaster thickness of 10-15 sufficient to cover the heating pipes.

On the visible side, there is a closed, jointless plaster wall for the heat conduction over a large area. This results in a high heat output or cooling output at low system temperatures and save energy cost.
