PYD®-ALUFLOOR screedCooling of surfaces

• Double usage in heating and cooling

Die PYD®-THERMOSYSTEME can not only be used for heating but also for cooling in the summer. This enables a double usage of PYD® systems and opens up another fi eld of application.Due to reasons of physics, cooling by means of the fl oor yields a smaller cooling capacity than by means of ceiling. With a relatively small additional effort for example a heat pump can be completed so that a fl oor heating system can be used in summer for cooling rooms, as well. Doing so a cooling capacity of up to 58 W/m² can be reached, with respect to the high heat transition number α of PYD®-THERMOSYSTEME. The performance achieved depends on many factors, though.Nowadays, since many times the required thermal loads, and respectively cooling capacities, are signifi cantly higher than the heating load in most cases, an individual consideration is required.Dimensioning of the systems is adjusted to the case of cooling without neglecting the aspect of comfort..

• Health and comfort

Conventional air conditioning systems use cool air to remove the thermal load. Air in subtemperatures is blown into the rooms in great amounts.In some cases this can lead not only to a reduction of comfort, but also to impairments to health, as well. Besides the risk of draught and exposure to noise, defi cient hygienic conditions of the air channel system, in many cases caused by insuffi cient maintenance, often contribute to an impairment of health. Maintenance of our systems’ heating/ cooling surfaces is not necessary.

PYD®-THERMOSYSTEME work completely silently and without draught. This is why it’s sometimes called “silent cooling“. The exchange of energy by means of radiation corresponds to natural conditions and is percieved as very comfortable.The user perceives the room ambient to be comfortable due to the cooled surfaces, even though the room temperature may be relatively high. The chart below shows this. Additionally, the surfaces have a homogeneous profi le of temperature without great differences or a wave-like pattern due to the ideal distribution of temperature.This means that every occupant is provided with the exact same conditions and the „traditional“ discussion about better or worse work places, when it comes to terms of room ambient, has become obsolete.

• Setting the direction for climatisation of buildings

Nowadays, the occupant and operator have high demands on air-conditioning and heating buildings. When it comes to comfort, conventional heating systems such as static heating surfaces, climate and ventilation systems are depleted soon and only suitable with restrictions. In our times it’s important to use all the space provided ideally and at the same time conserve as much energy as possible. This should all be achieved while providing for an optimum of cosiness, comfort, and user-friendliness.Alternative sources of energy like terrestial heat exchangers or convertible heat pumps can serve as chiller units to produce chillness.

The technology of PYD®-THERMOSYSTEME opens up new, almost unlimited possibilities in this fi eld. Aluminium heat conducting sheets moulded in the shape of pyramids are integrated close to the areas of the room that encompass surfaces and adjusted to the required temperatures by means of heating or cooling water. Due to the unique moulding, an utmost of effectiveness can be achieved, redundant mass that saves energy can be conserved, and little space is used for pipes that bear water.The occupant still has the chance to adjust the room temperature himself and suit it to his request. Regulating temperature by means of heat radiation is in correspondence to the natural circumstance within most living creatures that regulate their body temperature the same way. Due to the background in nature this is perceived to be highly comfortable. Due to the great surface for transfering heat actively of PYD®-THERMOSYSTEME, small differences of temperature between the activated mantle surfaces of a room and the temperature of the air of a room suffi ce to transfer great amounts of energy noise and draught free.

• Laying and planning

We would like to assist you specifi cally in planning and laying, with regard to the individual needs of your project. Please don’t hesitate to contact us about it.

• Lower deviation of the dew point

In order to avoid the danger of a lower deviation of the dew point and the formation of condensate that comes with it, dew point detectors are installed in the individual zones of regulation. In case the dew point detector detects condensate, either the supply of cooling water to the activated surfaces will be discontinued or, optionally, the fl ow temperature of the cooling medium will be raised slowly, until the formation of condensate is no longer possible.The case of lower deviation of the dew point can be almost excluded in offi ce buildings since there often is an additional ventilation system installed in those buildings, in order to secure the minimal turnover of air and keep the relative air moisture at comfortable 50%. This means that a range that is free from dew points is maintained.

Since the eduction of cooling loads in the construction concept mentioned is undertaken by one of the PYD THERMOSYSTEME, the use of the air ventilation system can be reduced to a minimum. Thus, the space requirement for the air ventilation system is reduced and as a matter of that fact the cost of the system, as well.

screed admixtures/ - componentsfor the individual floor construction using cement screed

There are different possibilities to keep the height of the fl oor construc-

tion as low as possible. The following components enable the reduction of the height of screed. The fl oor construction is adjusted to the construction project

PYD® steel fibres

Different thicknesses of screed can be re-alized with PYD® steel fi bres, depending on the amount added.

Adding steel PYD® fi bres enables for a reduction of the thickness of the screed down to 35mm. The screed’s bending and tensile strength is increased and the heat conductivity improves signifi cantly in comparison to the initial usage

• Thickness of screed with PYD®-ALUFLOOR from 35mm

• Conservation of up to 46% of screed mass

PYD® steel fi bres are approved for the use with screed pumps

PYD® special screed admixture

An additional option of reducing the thick-ness of screed is by adding PYD® special screed admixture, which enables for the realization of the thickness of the screed

of 50 mm, including PYD®-ALUFLOOR. In this case bending and tensile strength of the screed is not increased by reinforce-ment as in the case of PYD® steel fi bres, but by a change in the chemical composi-tion of the screed.

• Thickness of the screed including PYD®-ALUFLOOR from 50mm

• Conservation of up to 31% of screed mass

PYD®-retrofit

In order to keep the height of the fl oor constructional system as low as possible when refurtohing an old building, PYD®-ALUFLOOR offers the option of installing the system directly on the existing fl oor covering or screed (load distribution pa-nel). Since the load distribution panel has already been installed, it is suffi cient to merely even out the dales in between the pyramids with cement screed

• screed thickness with PYD®-ALUFLOOR from 20mm• Conservation of up to 75% of screed mass

PYD® separation and decoupling mat

Die PYD® separation and decoupling mat is used in contact with ceramic coverings in refurtohing old buildings. It is used for decoupling the covering and subground in private residential

construction, or in likewise used fi elds in non residential construction to eliminate damage on the load distribution panel caused by movement. In non-residential construction exceptional approvement is to be coordinated with us.

• Decouples the covering from theunderground

• Ventilation in all directions

PYD®_tempo special screed admixture

This screed admixture provides for a faster hardening and drying of cement screed by increasing its mechanical properties. As a matter of that fact, the heating process in accordance with DIN 4725 can be started after 10 to 14 days.

• Accelerates the drying process of thescreed

At a thickness of 65mm of the screed a load of about 110kg of screed per m² should be assumed. This approximates about 17 kg/(cm x m²)

To prevent the system pipe from bouying upwards when fl oating screed is applied, it is fastened every 0.75m and at the cut-out of the PYD® assembly bend. The sheet metals should be stepped onto in the area of the PYD® system pipes. Stepping onto the sheet metals in the center is to be avoided

13) Laying of the aluminium heat conducting sheets

After fastening the lines for tying down, the PYD® aluminium heat conducting sheets are installed. To do so, the PYD® system pipe is lifted a little and pushed into the designated channel of the PYD® aluminium heat conducting sheets. It is to be attended to lay the PYD® aluminium heat conducting sheets in the position pictured. When installing PYD®-ALUFLOOR VV the distance between the sheets is 2-3cm, for PYD®-ALUFLOOR NV the distance is 20- 25 cm

11) Fastening the lines for tying down

1) 2)

The lead for fastening the lines for tying down is indicated in the laying plan. All fastening lines for tying down are fastened onto the PYD® folded panel with PYD® system clips and the PYD® system clip tool every 0.5 meters. Redirections of the pipe can either be guided freely as illustrated above (see 1) or, if required, be redirected by a 90° angle by means of the PYD® laying angle

12) Coating of the sheet metal

Warning:Before delivery it has to be determined whether cement or calciumsulfate screed is used. When using calcium sulfate screed PYD aluminium heat conducting sheets have to be coated black

Duration of assembly:

PYD®-ALUFLOOR system for screed fi ll and its components for installation is designed very simply. You can estimate about 5-7 group minutes per m² (basically, this depends upon the condition and preparation of the subground.

This time specifi cation includes installing the PYD® edge insulating strips and PYD® folded panel, as well as installing the fl oor heating system with a connection tot the PYD® heating circuit distributor. Setting up the PYD heating circuit distributor and distribution box is estimated to take about 30 minutes
