PYD®-ALUTOPCeiling heating

• Prerequisites for laying and comfort

Some things have to be taken into consideration:

1. Rooms with a height below 3m are suitable for the installation of a ceiling heating system only to a limited extent.

2. In accordance with DIN 1946 part 2, comfortable conditions have to be provided for the occupant. These conditions are defi ned as such:

- Distance to the exterior wall 1,0 m- Distance to the interior wall 0,5 m- Height above the fl oor of up to 2 m- The air temperature between the heights of 0,1m and 1,1m from the ground must not have a greater difference than 2 K/m, in

accordance with DIN 1946 part 2.- The fall of cold air in lounging areas must not cause a speed of the air that is >0,15 m/s.

3. The Room temp. has to be set out about 1-2 K higher than in fl oor heating systems, according to the profi le of temperature!

PYD®-ALUTOP warms up the surfaces that encompass the room fi rst. The median surface temperature of PYD-ALUTOP should not be above 30° C at a Room temp. of 22° C. An increase of the surface temperature is not recommended due to the asymmetrical nature of radiation that may arise then.

PYD®-ALUTOPCooling of surfaces

• The dual usage heating/cooling

PYD®-THERMOSYSTEME cannot only be used for heating, but also for cooling in the summer. This yields a dual usage and another fi eld of application. With a relatively small additional effort, a heat pump can be run in a way so the ceiling heating system can be used for cooling in the summer. Doing so, a cooling capacity of up to 90 W/m² is possible, relating to the high heat transition fi gure α of 15 W/m²K of our systems. Yet, the performances achieved depend upon a variety of factors.A consideration of individual cases is necessary, since nowadays the heating loads and respectively cooling loads adductable, are signifi cantly greater in most cases. The dimensioning of the system is conducted with respect to the case of cooling, yet 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 perceived as very comfortable. The user perceives the room ambient to be comfortable due to the cooled surfaces, even though the Room temp. 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.

Duration of assembly

PYD® ceiling system and its components for installation are designed very simply. You can estimate about 20-22 group minutes to be the required period of time for laying (basically, this depends upon the condition and preparation of the subground).This time specifi cation includes installation of the mounting wood bars, PYD foam foil, PYD assembly bows, as well as their alignment, cut and assembly. Furthermore, installation of PYD system pipe with a connection to the heating circuit distributor as well as the set-up and fi xing of PYD aluminium heat conducting sheets are included in this time specifi cation

9) Installation of PYD® system pipe

PYD® system pipe is pulled over the arch of the assembly bow and hooked in. In order to retighten the PYD® system pipe, it is compressed about 20 cm in front of the bow and pushed/ pulled as far above the PYD® assembly bow until the pipe is straight

7) Connection of the flow to the PYD® heating circuit distributor

In order to feed the PYD® system pipe to the heating circuit dis-tributor without tension, the boiler tube is pushed through PYD® laying angle. Afterwards, PYD® system pipe is connected to the fl ow of the heating circuit distributor with the PYD® adaptor and conducted to the correspondent room indicated in the laying plan

10) Connection of the return to the PYD® heating circuit distributor

After the ceiling has been covered with PYD® system pipe as indicated in the laying plan, the pipe is guided back to the PYD® heating circuit distributor. It is cut fi ttingly, pushed through the laying angle pipe, and connected to the return of the PYD® heating circuit distributor with an adaptor
