Heating and cooling applications for Industrial projects velta one – floor heating and cooling system The velta one system is an embedded pipe system within the structural ground floor slab, which can be activated with warm water or cool water to provide both heating and cooling in a building. Installed in the same construction sequence as the floor slab the system provides programme benefits compared to alternative systems, which have to have a separate programme period. The standard velta systems can be incorporated into traditional flood pour construction of the floor, but the velta one system has been specifically designed for installation in floors utilising modern laser screed floor laying techniques. This allows fast and accurate installation of the concrete floor with the embedded velta system in one operation.

Benefits of the velta one system The velta system provides many benefits

• Low maintenance costs – minimal moving parts and all maintenance at floor level. • Long life expectancy – the system is designed to last the life of the building. No replacement costs throughout the life of the building. • Environmental - No disposal issues of used equipment. • Health and Safety – No high level maintenance required • Links with renewable energy sources – velta system can utilise most forms of renewable energy sources due to the low temperature heating water and high temperature cooling water requirement • Low running costs for energy • Heating/Cooling provided at the occupied floor level • High radiant component with the system reducing energy requirements for the building by 6 – 12% • Freedom of space – invisible system • Future flexibility of heating/cooling source to supply the built in velta system • velta service – design, supply, installation and commissioning with directly employed velta staff

Design Philosophy

The Design philosophy for the building should be undertaken utilising the high radiant effect associated with floor heating. This philosophy usually leads to a reduction in the internal design temperature, as operative temperature should be utilised and not air temperature. It is common for operative to be up to 2 ยบC lower than air temperature and this can lead to energy savings of approximately 12%. With the floor surface acting as the emitter the heat load demand can be based on the occupied zone which is usually the first 2.5m of space rather than the total height or volume of the building which is often the case for other heating systems. This leads to a reduction in the heat loss for the building and can lead to a reduction in the plant required for the heating and cooling load.

The award winning designed, flagship B&Q store in New Malden, London which will benefit from having 10% of its energy needs catered for by renewable energy sources on site. The concept for this store was to demonstrate the store design and construction of the future, utilising renewable energy sources though energy piles and solar panels. The systems used within the building and the construction methods also had to adopt this philosophy and demonstrate environmental benefits. A velta classic heating and cooling system was incorporated into the retail floor area extending to 9,000 m². The system was installed in the composite structural floor consisting of precast concrete units and structural concrete topping. The installation was undertaken with the concrete flooring programme, causing no delays and the system set to allow a bolt drilling zone for floor fixings.

The velta one system was used in this application to maintain a high level of comfort to the warehouse area.The heat was in the occupied zone which helped achieve the comfort levels required. The thermal mass of the system means that the system is instantly reactive to sudden changes in temperature due to the doors opening and closing as the buses come and go. The plant to serve an air system would need to have been over 35% larger to cope with the demands on the building usage. The system had a built in drill zone of 75mm to enable fixings into the slab.

This luxury tile showroom used a combination of the standard velta slab system and velta one system to deliver a dual purpose system. In the showroom the standard velta slab system was used to showcase the comfort achieved by utilising a tile finish underfoot. In the warehouse area the system was used to dry the stone imported in from Italy. The warehouse system was designed to achieve an output in excess of 120W/m² and due to the stable heating effect of radiant heating this helped to decrease the standard drying times of the stone significantly.

Cooling and heating design data Typical data associated with a system of this nature would be as follows: Internal temperature Heating/ Cooling Output: Flow water temperature: Return Water temperature: Av. temp. of the concrete surface

Winter mode 18°C 60 W/m2 37°C 31°C 24.5°C

Summer mode 26°C up to 40 W/m2 14 °C 18 °C 20.5 °C

Control and zoning The building can be split into a series of zones and each individual zone controlled to different conditions, allowing for future flexibility for re-design of the building function and layout. The velta one system can be controlled from standard BMS systems.

Manifolds The velta industrial manifold can serve up to 450m² and can be used to serve dedicated zones. These zones can be controlled individually if required or as a one for the entire building. The control philosophy can be changed at a future date as long as sufficient zoning is designated in the initial design. Each zone can be either in cooling or in heating mode. We suggest that the decision of changeover between heating and cooling is based on the whole building and not individual zones. velta manifolds can be located vertically on walls and concealed in cabinets or they can be placed horizontal within the floor slab itself with the appropriate steel covers. Primary pipework to the manifolds can be treated in a number of ways. Overhead solutions can be considered or the pipework can be embedded under or within the structural slab. Alternatives have also been constructed with the primary pipework running underground external to the building.

Ground floor slab construction The velta one system can be incorporated into most concrete floor slabs with insignificant modification to the floor slab depth and construction. The system has been used with Lafarge Extensia concrete, which eliminates the requirement for reinforcement and minimises the use of joint profiles due to the low shrink properties of the new material. This provides environmental benefits and can also be polished to provide the permanent floor-wearing surface. The properties of Extensia also allow the floor slab depth to be reduced. This is an alternative to the terrazzo floors currently used. A single monolithic construction producing the heating and cooling with the finished wearing surface of the floor.

Concrete joint formation Joint requirements Structural engineers are responsible for planning joints in the structural concrete floor and the velta heating system is not a critical factor due to the low temperature of the water used to heat the floor and the high temperature of the water used to cool the floor. Standard bay sizes and pour profile proportions apply dependant upon the concrete and the reinforcement utilised. Standard joint profiles such as Alpha type, can be used with the velta system and velta request a joint plan in order to coordinate the pipework circuits and the connecting pipework to minimise the crossing of formed joints.

Expansion / Movement Joints The velta system does not influence expansion joint planning. Heating pipes that cross expansion joints should be protected using velta 1m protective pipe sheathing due to the anticipated mechanical loading in the area of the joint.

Pipe design should be undertaken such that no movement joints are crossed.

Induced / Sawn Joint A velta protective pipe sheath is not required for induced or sawn joints. The joints can be sealed by making a subsequent cut of approx. 25mm depth and using a suitable special sealing compound with partial filling using cellular rubber. Other standard joint profile techniques can also be used.

Floor Fixings The foundations of racking or equipment are often anchored in the concrete floor.Velta must be informed of the depth of these foundations or anchoring in the concrete slab. There is rarely a danger that these will penetrate as far as the level of the heating pipes. However, if this occurs due to insufficient thickness of the concrete, then the heating pipe in this area should be omitted.
