18 1.1 MAIN PRINCIPLES OF RADIANT HEATING/COOLING Tiemme s radiant solutions guarantee an excellent thermal environment for both living and working, at an optimised cost. Our low consumption solutions are ideal for the use of renewable energy sources and help reduce energy consumption and CO2 emissions thus offering the best basis for an ideal indoor climate. Tiemme offers water based underfloor, wall or ceiling heating and cooling systems. Radiant systems work at low temperatures and, for such reason, result to be the most energy-efficient way to distribute heat within a building. Low temperatures guarantee maximum efficiency of the heat sources, ideally renewable sources such as ground heat or heat pumps. This results in low energy consumption and less CO2 emissions. In addition, radiant heating offers a very high level of comfort to occupants and can be used for cooling. The installation is invisible and provides maximum architectural freedom. There is no reason why a different type of heating or cooling solution should be selected for the cooling or heating of indoor environments. 18

19 DESIGNING WELLBEING Based on the radiation principle, the radiant heating/cooling system is surely the most innovative, flexible, healthy and efficient method for guaranteeing comfort in any type of building. Using the floor as a heating/cooling element makes it possible to use a low temperature fluid, hence obtaining maximum comfort thanks to radiation together with considerable energy and money saving. How it works An underfloor heating system works by circulating low temperature hot water (35 40 C), through a closed network of circuits formed by pipes - mainly made of thermoplastic material - embedded in the screed on which the flooring is laid. The circuits create a large radiant surface, which heats the environment from the floor to the ceiling, stratifying the heat according to an ideal temperature curve: warm feet and cool head. This type of radiant heating is basically the opposite of the distribution generated by radiators or fan coils. In fact, in rooms heated by radiators or fan coils, heat is stratified towards the ceiling causing considerable energy and money losses which may result in reduced comfort. 19

20 It is not continued life as such that is desired, but good life. Plato EXCELLENT COMFORT Comfort is the condition of psychological and physical wellbeing which, based on the feelings of each individual, is determined by temperature, air humidity, noise and light in an environment. It is clear that the scope of a radiant system is Thermohygrometric comfort, greatly influenced by the type of heating/ cooling system. A radiant system, mainly functioning on heat transfer by radiation, promotes a feeling of wellbeing similar to the feeling of wellbeing induced by sun exposure on winter days. Even though at low temperatures, the sun s heat supply is transferred to our body creating a pleasant feeling of wellbeing. Laboratory tests have shown that a correctly rated and implemented radiant heating system is the system closest to the perfect curve where temperature stratification determines heat concentration mainly at floor level and a cooler environment as the heat rises towards the ceiling. This phenomenon is reversed when the system is provided with radiators or fan coils. 20

21 TOWARDS SUSTAINABLE CHOICES The achievement of the targets provided by the Kyoto Protocol, the binding commitment of the European Union to raise the use of renewable energy sources to 20% of the total energy consumption within 2020, and the energy performance requirements of buildings as per European Directive 2002/91/ EC are all factors which lead towards sustainable choices for building systems. It is important to remember that today buildings are responsible for 40% of all energy consumptions in Europe. Saving is the first energy source at our disposal and improving energy efficiency cannot be other than a common target. High energy efficiency = Money saving Mainly based on heat transmission by radiation - and only a small part by convection a radiant system reaches a high efficiency level even at a temperature normally ranging from 35 and 40 C. The fact that the thermal head between the radiant system s temperature and the environment temperature is very small reduces heat losses to the minimum, thus considerably improving the system's efficiency. The low temperatures of the system s carrier fluid drastically reduce the need of energy; the average energy saving per year is 20% in domestic systems reaching maximums of 40-50% in the case of buildings with high ceilings such as depots, places of worship or gyms, etc. Clearly, this energy saving can automatically be converted into a considerable money saving. Radiant heating and cooling, an ecologically valid and consciously aware choice. The previous paragraph underlined that the radiant system leads to a certain energy saving and consequently to a money saving. But shouldn t the use of less energy also become our contribution to safeguard our planet? Saving energy is not only an economic advantage, but must also become a consciously aware choice for our future. 21

22 1.2 STANDARD ON RADIANT SYSTEMS The Uni EN 1264 standard is the technical guideline that defines all the elements of an underfloor, wall and ceiling system. This standard indicates the calculation methods for the design of radiant systems. In this part, we will only summarise the main points related to what has already been previously said on environmental wellbeing, whilst attempting to give an indication of the parts that can be of help in the design and installation of these systems. The insulation layers The standard pays particular attention to the thermal resistance of the insulation layer between the system and an external wall or between the system and an adjacent room. "Insulation layer" indicates what is placed immediately under the piping and also identifies a layer composed of the coupling of two or more panels.

26 TIEMME RADIANT SYSTEMS: THE SOLUTION FOR EVERY OCCASION WHY THE UNDERFLOOR RADIANT HEATING SYSTEM? Better heat distribution Radiators transfer heat by convection pushing warm air upwards and consequently cold air downwards. In case of underfloor heating the distribution occurs by radiation, phenomenon that guarantees a constant temperature throughout the environment. Compatibility with renewable energy A system with radiators requires gas or diesel heating that can heat water to temperatures between 70 and 80 C. The underfloor system works with much lower temperatures between 35 and 40 C and for this reason it ensures maximum compatibility with more environmentally friendly energy sources such as pellet boilers, heat pumps and solar energy systems. Reduction of dusts, mites and moulds The presence of radiators produces dusts that annoyingly spread throughout the environment because of the convection. In case of underfloor heating, this issue is largely minimized as well as the presence of mites and moulds. Full freedom of organization of internal areas Radiators limit the internal space making the walls on which they are placed unusable. The underfloor heating system makes it possible to save space making the walls fully usable. Full freedom of choice of the floor The radiant system is compatible with any kind of flooring: from laminates to tiles, from carpeting to earthenware tiles. Special attention shall be adopted with wood and with the choice of a stable and small parquet. 22 C 17 C 40 C 18 C 20 C 16 C 22 C Radiator heating Underfloor heating 26

27 GRAPHITE SYSTEMS WHY USE GRAPHITE? Graphite is one of the allotropic forms of carbon. It has a crystalline structure with carbon atoms arranged on parallel layers and consisting of a regular hexagons weave with a carbon atom on the vertices. Thanks to this particular honeycomb molecular structure, the graphite particles absorb and reflect the stored heat and minimize the heat transfer by radiation. In order to harness this insulating property, Tiemme chose to offer radiant systems based on graphite panels within its range: - NEW CLASSIC GRAPHITE - TECHNO GRAPHITE 27

50 ACOUSTIC WELLBEING 2.2 SOUND-INSULATING SYSTEMS One of the factors related to the radiant system and connected with home comfort is the acoustic wellbeing. It can be defined as the condition where a person is not disturbed by extraneous sounds and no damage caused by a protracted exposure to noise sources may occur to the hearing system. In particular, the sources of acoustic disturbance inside a building are mainly two: the external and the internal sources. The external sources mainly consist of the road traffic and the possible presence of industrial productive activities close to the building. The noise arising from the external sources spreads by air and then penetrate the building through its shell. The technological and structural characteristics of the facades are decisive for a greater or minor resistance to the internal diffusion of the sound waves coming from outside. In this sense, openings such as windows or ventilation grilles represent the weakness of the building in defense against the noise A B C The internal noise sources, which can specifically be related to the environment in question or other environments of the same building, are the facilities (lifts, hoists, hydraulic system, etc.), the domestic appliances, radio and TV equipment, voices, shouts and the movements of the building occupants. In this case the spread happens both by air and through the solid parts of the construction. A. Footstep noise B. Direct spread C. Lateral spread 50

51 SOUND-INSULATING SYSTEMS: LAWS AND REGULATIONS The realization of a radiant system has an impact on the structural aspect of the building, so let s talk about internal noise sources, specifically footstep noise. The law (D.P.C.M: 5/12/97) defines different aspects of the passive acoustic requirements of buildings and we are particularly interested in two of them: 1 The footstep noise limit inside a residential building must be less than 63 db 2 This value must be measured on site (this means that inside the noise source sound-insulating material final result system, the laying comes into play too). However, we need rules that forerun the realization itself to design a building. The European standard EN recommend two methods of calculation respectively called detailed model and simplified model. Certainly the calculation results do not take into consideration either possible defectiveness of the materials or installation errors (not quantifiable). In case of residential buildings with brick and/or concrete masonry or floating floor, it is possible to apply the simplified model. The expression of the footstep noise rating index is the following: where: L n,w,eq K ΔL w L n, w = L n, w, eq + K-ΔL w It is the normalized footstep noised rating index of the floor lacking in acoustic insulation (bare floor) and it is a value calculated according to the mass of the floor per unit area (m²). It is the corrective factor for the lateral spread of the footstep noise according to the mass of the floor and to the average mass per area of the disturbed environment s walls (m²). It is the footstep noise reduction rating index and it is calculated according to the mass per unit area of the floating floor (m²) and to the dynamic stiffness of the sound-insulating carpet. Here the acoustic insulation of the radiant panel and its footstep noise-absorbing characteristics come into play. Among the range of Tiemme products you can find panels, such as Silento, which have sound-insulating characteristics with important values (up to 28 db) and that can help the client to meet the legislative requirments. Diagram In the diagram you can find the rating index of the attenuation of footstep sound pressure level for floating floors made of cement mortar or calcium sulphate according to UNI EN Legend: A Rating index of the attenuation of sound pressure level ΔLw [db] B Mass per unit area of the floating floor [kg/m²] C Dynamic stiffness per unit area of the resilient layer [MN/ m³] 51

52 SILENTO Silento is an innovative system whose panel was designed to thermally insulate the floor and to hold the pipe but above all to effectively eliminate the footstep noise. It was possible to achieve this goal using the EPS-T, a high-performing material obtained by and advanced industrial process and further enhanced by a particular geometric conformation of the panel bottom. Finally, to give the EPS-T further solidity and reliability characteristics, it was coupled with a thermoformed that can take high loads both during laying and while in use Baseboard 2 Floor 3 Screed 4 Pipe 5 Panel 6 Peripheral strip 7 PE film Code Dimensions A B C C A B 52

65 2.4 INDUSTRIAL USE SYSTEMS Nowadays the underfloor radiant heating systems represents the best way to heat warehouses, depots or other industrial environments characterized by large sizes and considerable heigths. A good industrial use radiant system must be both energy efficient and resistant to the stresses arising from the heavy loads to which it is subject. Tiemme is a leader in the design and production of industrial use radiant systems and recommends different solutions to best interpret any situation. >>> 65

66 INDUSTRIAL USE SYSTEMS Energy saving Choosing to heat a very large environment with an underfloor radiant panels system means significantly reducing the handling costs. Compared to an air system, you can achieve fuel savings up to 50%. Using the whole useful floor area as a radiator, the industrial system allows to operate at very low temperatures and to make the best use of low-temperature and condensation heat generators. Moreover, the heat transmitted by radiation by the flooring concentrates in the user s apron and not near the ceiling where it would be useless. In fact, compared to an air system that creates stratification phenomena, an underfloor radiant heating system produces an almost linear thermal gradient, so that in the highest part of the structure the air temperature tends to decline. These characteristics allow to significantly reduce the heat losses by transmission, because the temperature difference between the indoor and the outdoor environment close to the dispersant structures and the coatings is significantly lower. The considerable reduction of thermal dispersions allows installing a heat generator with a decidedly low power compared to other kinds of systems and anyway obtaining better comfort levels. The use of lower thermal power corresponds to the reduction of the payloads that have to be provided to the system and therefore of the supply pipes diameter to the collectors and of the circulators characteristics. Another important factor for the energy saving is the fact that the radiant system, operating at low temperatures, makes it possible to use the heat originating from alternative energies determining further reduction of the heating costs and allowing to amortize the initial realization costs, slightly higher compared to other kinds of system, in short space of time. The comfort Thanks to a homogeneous heat distribution, the radiant system creates an extremely comfortable environment. The heat generates in a moderate and uniform way and the body perceives it in an extremely natural way: the exchange between source and environment occurs by radiation and the perception of the heat seems similar to the solar one. The heat radiated by the floor concentrates where it is really needed and it creates a climate that is physiologically optimal for the human body consequently improving working conditions related to thermal comfort. For this reason the radiant technology is more and more widespread also in industrial matters. 66

67 INDUSTRIAL USE SYSTEMS Fire and safety In many cases in the industrial depots some production processes that involve highly flammable materials occur. Even in this case, an underfloor heating system provides undeniable benefits: the absence of high-temperature heating structure has a positive impact on the safety level in the working environment. Maintenance The low-temperature heat-carrying fluid allows less strain of the different components of the industrial heating system (heat generators, piperworks, fittings, seals) and we can have a further reduction of maintenance costs, this being an underfloor system. Absence of air convection movements A traditional air heating system generates significant temperature differences between the heat sources and the air itself, producing annoying convection movements. Differently, in a radiant panels heating system the temperature difference between the floor and the adjacent air is around 5 C, difference that is not sufficient to determine convection movements and the consequent drifting dust. Moreover, the elimination of high-temperature heat sources offers the benefit to avoid the combustion of air dust, reducing the risk of allergies and ensuring healthy environments and optimal hygienic conditions. Use of alternative energies The high exchange surface of the underfloor heating allows to operate with a low-temperature heat-carrying fluid. Therefore, the system can recover and make the best use of the heat originating from working processes, heat pumps, solar energy, spring water, etc. with a further reduction of heating costs; at best, these costs can even reset.

76 3.1 RADIANT CEILING SYSTEMS The ceiling heating system spreads the heat in any room of the house through an exchange by radiation between hot and cold surfaces. What is it about? Radiation is a phenomenon that frequently occurs in nature when a surface absorbs the heat contained or generated by a surface with a relatively higher surface temperature. Similarly, the walls of the room where the ceiling heating system is located represent the cold surface and accumulate the heat generated by the false ceiling, spreading it in the environment and heating it. >>> 76

77 WHY CHOOSE A RADIANT CEILING SYSTEM? It does not need any masonry work The ceiling heating is a low-cost solution because the installation of the radiant panels that make up the system doesn t need any demolition or other masonry work. Heat homogeneity As far as the ceiling heating is concerned, the heat distribution is homogeneous and it allows a fair exchange between the environment and the radiant system. In this way, a heating without extreme changes in temperature is guaranteed. Practicality of laying and versatility of use The radiant panels are already settled, preassembled and they are ideal both for the heat production during the cold period and for the cooling in the hottest periods of the year. 4 Minimized obstructions The radiant ceiling panels are an invisible heating system without obstructions. Their thickness is less then 50 mm and the kind of laying does not bind in any way the environment where they are installed. 5 6 Wide architectural compatibility The ceiling heating system presents many modularity features and perfect architectural integration and it allows to adapt the panels to any kind of ceiling. Reduction of moisture, molds and bad smells. The heat distribution through thermal exchange allows a reduction of moisture, molds and bad smells. This is an even more appreciable characteristic in the north zone of the house where the formation of unwanted microorganisms is more common. 22 C 24 C 22 C 40 C 20 C 16 C 18 C Radiator heating Ceiling heating 77

Pipe disconnection Please operate the following operations in succession: 1 Turn the bayonet connector counterclockwise through a wrench. 2 Disconnect the bayonet connector. 3 Remove the stainless steel tweezers from the pipe through cutting pliers. 4 Insert the replacement kit in the body of the fitting, paying particular attention to the stainless steel tweezers whose teeth must face the body of the stainless steel fitting. 3 Mark on the pipe the required insertion depth: endstop = 39 mm. 5 Reconnect the bayonet connector, turning clockwise through a wrench. 4 Insert the pipe in the fitting as far in as it goes, verifying that the mark indicated in the previous phase is flush with the fitting head. Connection to the side outlets: PEX pipe Ø8 mm Please operate the following operations in succession: 1 Cut the pipe perpendicularly to the axis through specific cutter. 2 Mark on the pipe the required insertion depth: endstop = 22 mm. 3 Insert the pipe in the fitting as far in as it goes, verifying that the mark indicated in the previous phase is flush with the fitting head. Finalisation and closing of the system After the positive result of the tightness test, it is possible to complete the installation of the ceiling/wall radiant system. Non-active areas must be covered with the specific planed panel or The panels measure 1200 x 200 mm, so they must be shaped in function of the amplitude of the areas to be covered. Alternatively, it is possible to use non-insulated plasterboard panels of commercial provision. Then we proceed with the smoothing and grouting of the joints in the panels and the realization of the desired surface finish. Pay particular attention to the distribution manifold installed in the false ceiling: always provide the realization of an appropriate inspection/maintenance hatch. In simple terms, hereinafter you can find the installation phases of a radiant ceiling. 92

93 LAYING OF THE RADIANT CEILING SYSTEM Illustrated sequence Notes for the laying of the radiant system The typical hydraulic connection for a radiant ceiling system is shown in the figure. The distribution manifold is directly fixed to the slab. With the wall system it is possible to use a more traditional distribution manifold integrated into the wall. The designed flow rate envisaged for every hydraulic circuit is 20 l/h and it involves a pressure drop around 4 kpa. Moreover, it is recommended to guarantee a flow rate of at least 140 l/h for every ring (every exit of the distribution manifold) to allow the passing of the critical speed needed to eliminate the air in the pipes. The main adductions, from the manifold to the panels, are realized through an insulated multilayer pipe of 20 x 2 mm. The connection fitting uses fast-coupling elements realized with polyamide 66, reinforced with glass-fibre at 30%. The main components are shown in the figure. 93

96 4.1 RADIANT SYSTEM PIPING A good radiant heating and cooling system requires piping with excellent technical features. >>> 96

97 RADIANT SYSTEM PIPING One of the main elements of a radiant system is surely its piping. Fluid circulation in the system occurs through the piping; the chemical/physical properties of the pipe strongly characterise heat exchange between the pipe, screed and environment. For such reason the best pipes to use would be those made of materials having a high thermal conductivity coefficient such as steel or copper but by observing the modern heating and plumbing systems, we can note that these materials have been widely replaced by plastic or metal-plastic materials. The replacement with these materials has been made based on the many advantages that they present, among which, more specifically: Plastic or metal-plastic pipes have now reached a high level of long-term reliability with regards to resistance to mechanical stresses caused by operating temperatures and pressures of the systems. See the "Regression curves of PEX pipes" diagram at page 98. If correct galvanic isolation is not ensured, metal pipes may lead to events of corrosion able to cause severe damage to the system. In these cases, it is even more expensive to intervene due to the fact that the piping is embedded in the cementitious screed. On the other hand, plastic pipes are not subject to the risk of corrosion. Plastic pipes allow - the designer first and then the installer - to consider distribution layouts, such as to obtain maximum system efficacy/effectiveness (such as single or dual spiral or serpentine channels). This design freedom and installation versatility are unimaginable with metal pipes. The wide use of this pipe type and the low fluctuation of the prices of the raw materials used allow producers to maintain very low market prices even though the product is a very high quality product. PEX-b Cobrapex Oxistop pipe with EVOH oxygen barrier COBRA-PEX plastic pipes in cross-linked polyethylene are characterised by a high molecular weight and high density (d 0.95 g/cm³). Experienced acquired over the past decades, teaches that when high mechanical and chemical resistances are required, it is necessary to use high molecular weight polyethylene. However, to guarantee long-term reliability under any operating conditions and at high temperatures (>40 C), it is necessary to use high-density material exposed to a further process, to improve the chemical-physical features. This process is known as molecular cross-linking. The cross-linking process consists in creating transversal molecular bonds among the various independent chains to form a three-dimensional network. >>> 97

98 RADIANT SYSTEM PIPING Three cross-linking methods (two chemical and one physical) can be used: PEX-a: chemical cross-linking by means of catalysts known as peroxides which permanently cross-link the pipe during extrusion PEX-b: chemical cross-linking by means of catalysts known as silanes. However, in this case, the cross-linking process is accelerated after extrusion by submerging the product in temperature controlled water or vapour PEX-c: physical cross-linking by means of electronic irradiation. laboratory tests on the final product. The reference standard on the production of PEX pipes (EN-ISO 15875) specifies the physical and dimensional features of the product as well as the minimum cross-linking degree necessary to guarantee the adequate temperature and pressure resistance. For example, for PEX-b 65 % is sufficient. Tiemme produces its COBRA-PEX pipe, a quality pipe approved worldwide, with the chemical cross-linking method with silanes type b. The addition of the letter X originates from the English X-linked or cross-linked which indicates the linked bond between the various molecular chains created by cross-linking. It is important to underline that the pipe quality does not depend on the cross-linking method used but on many other factors such as the formulations of the base compound, the type of extrusion machines used, the accuracy of the production quality controls and, last, the testing phases and Regression curves of PEX pipes Maximum allowable stress σmax [MPa] C 40 C 60 C 80 C 95 C Reading the diagram the maximum allowable stress (σ max ) for a period of 50 years at a determined temperature can be identified by intersecting the line relevant to the 50 year period (the vertical axis) with the line relevant to said temperature (the horizontal axis). The equivalent pressure value can be calculated as follows: Pmax (bar) = (20 x σ max x Sp) / (D - Sp) where: σ max = maximum admissible stress (MPa) Sp = pipe thickness (mm) D = outer pipe Ø (mm) Note: the operating pressure (P es ), the safety factor will be equal to: Ks = P max /P es Stress duration h 50 Years For example: Fluid temperature = 60 C D = 17 mm Sp = 2 mm Duration = 50 years P max (bar) = (20 x 6 x 2) / (17-2) = 240 / 15 = 16 bar 98

99 RADIANT SYSTEM PIPING A radiant system needs more; annex 1 of the EN standard (reference standard for the manufacture of radiant systems) states the following: To reduce corrosion problems when combining plastic pipes with corrodible materials in heating installations, use plastic pipes carrying an oxygen barrier layer. At this point, the need for a COBRA-PEX pipe permeable to oxygen increases. This type of pipe is obtained with the deposit in accordance with the EN and DIN 4726 standards - of a particular barrier called "EVOH" with an effectiveness tested and approved by many international laboratories.

Operation principle G F H Thermostatic mixing valve Pump E By-pass valve D C L I Ball valve Check valve A B Temperature gauge N M O Safety thermostat Thermometer The high temperature water supplied by the boiler, through the ball valve (A) is mixed in the 3-way valve (C) with part of the water coming from the return manifold (I) of the underfloor heating system. The temperature of the secondary circuit is kept at the set value thanks to the thermostatic head (D) on the basis of the temperature detected by the bulb temperature probe (F). By enhancing fluid mixing, the pump (E) guarantees the pressure head in the heating panel circuits. The safety thermostat (G) electrically intervenes on the pump by turning it off if the fixed value (55 C) is exceeded. The water mixed to reach the required temperature is in this way conveyed to the delivery (H) of the underfloor heating system. Part of the low temperature water returning from the panels (I) enters the valve (C) where it is mixed with water supplied by the boiler, and part returns to the boiler through the ball valve (B). The check valve (L) impedes high temperature water from entering the heating circuits. The by-pass valve (M) makes system balancing possible by constantly guaranteeing the minimum flow rate of the primary circuit. The high-temperature circuits (heated towel rails, radiators, etc.) are supplied through points (O) and (N). 120

139 6.0 THERMOREGULATION CLIMAV Base concepts pag Advanced temperature control with CLIMAV 2.0 pag. 141 Operating Principles Examples of use 6.3 Climav 2.0 modules pag

140 6.1 BASIC CONCEPTS Temperature management in a radiant system mainly follows 2 modes: one is based on the distribution of the fluid at a fixed temperature value; the other, also known as "Climatic Control", is based on the distribution of the fluid at a temperature value that variates according to external environmental conditions. FIXED POINT CONTROL This is definitely the simplest and cheapest solution to regulate temperature in a radiant system. It regulates the plant's delivery temperature to a constant value and distributes it. The set value is generally the design value set to meet the plant's demand in the most unfavourable time of the year, so to ensure with reasonable certainty the ability to worm up the house at all times. The flaw in this solution is that it "yields" to the system the highest amount of power even when external environmental conditions would require far lower values. To overcome this issue, the distribution within the space is managed through various types of servo-controls regulated by thermostats/chronothermostats. In the following sections, the different configurations are analysed. Single area In a plant regulated by a single thermostat, this usually controls the fluid distribution pump that usually coincides with the boiler pump. Alternatively, the mixing group pump can be used to reduce the boiler output temperature to the plant's delivery temperature. This solution's shortcoming lies in the fact that the temperature control is determined by the position of the thermostat inside the house, and it is likely that the temperature will exceed the desired value in some rooms or not reach the target is others. This uneven distribution of heat usually leads to higher energy consumption and to a decreased comfort level. Living area - sleeping area A better redistribution of heat energy can be achieved by separating the house into two or more zones by installing two or more dedicated collectors, each one with its own circulation pump or zone valve. This allows to connect the pumps or zone valves to the respective thermostats and manage the temperature of the zones separately (the temperature in the sleeping area is usually lower than in the living area), increasing comfort and reducing energy waste. external accessories, it is possible to automatically activate or deactivate the circulation pump according to heat demand. Multi-zone configuration is certainly the most effective/efficient way to get the best comfort and highest energy saving. NOTE: As described above, fixed point control applies the maximum design power for each room, regardless of the external and internal environmental conditions. Subsequently relying on the internal adjustment made by the room thermostat, to limit this input. Moreover, the radiant system is a plant with a significant thermal mass, this generates a delay between the ignition of the thermostat and the achievement of the target temperature. This means that using the fixed point control, the screed is brought to temperature using maximum possible power and continues to be injected with maximum power until it reaches the target, creating an overshoot in the control. The cooling of the thermal mass then triggers the restart of the regulation system when the ambient temperature is lower than the differential set on the thermostat. At this point, the differential is an important element to analyse. In a radiant system, this factor should be as small as possible to minimise overshoot and, the gap between shutdown and system restart. As an example, the factory value of the differential of a thermostat is C; It would be desirable to bring it to +0.1 C. CLIMATE CONTROL Climate control allows greater efficiency and energy savings than fixed point adjustment. In this case, the system's delivery temperature and consequently the thermal power are not fixed but vary depending on external ambience temperature. The lower the outside temperature is, the higher the delivery temperature rises and vice versa. To define this function, it is necessary to select (within the family of curves on the climate controller) the curve that meets our needs. This usually depends on the type of building and the delivery temperature calculated according to project temperature. The controller is equipped with two temperature probes (external and delivery), a control for the mixing valve, a control for the circulation pump and an inlet for the probe (that can be connected or not depending on the central's algorithm). Remains valid what was said in previous paragraphs regarding the possibility of controlling the distribution, in particular in the "living area - sleeping area" and "multi-zone" mods. Multi-zone The structure and potential of a radiant system are fully exploited when thermal power management is applied in "multizone" mode. For this mode, thermostats are installed in each room, each of them controlling the corresponding circuit with electrothermal actuators installed on the distribution manifold. In addition to this, through a microswitch placed on each actuator or through 140

169 8.0 AIR TREATMENT 8.1 Dehumidifiers pag CMV dehumidifiers pag Accessories for dehumidifiers pag

170 The Controlled Mechanical Ventilation (or CMV) is a continuous operating automatic system for the air exchange that takes air from service environments to release it, fresh and filtered, in the other rooms. Moreover, a large part of the heat in the exhaust air is recovered further increasing efficiency of the system. A controlled mechanical ventilation system ensures the best air quality and a constant monitoring of temperatures, limiting thermal dispersions caused by the opening of windows or the formation of pollutants such as moulds or mites. 8.1 DEHUMIDIFIERS The FH series (vertical built-in unit) and GH (false ceiling ductable unit) dehumidifiers are designed to be combined with radiant panels cooling systems. These units are built to guarantee dehumidification both with thermal neutral air i.e. without any temperature change in the air withdrawn and with cooled air. The air flows are intentionally reduced in order to avoid the annoying air streams typical of traditional conditioning systems. The FH and GH series units proposed by TIEMME have the following features: all units are made of hot-dip galvanised sheet to ensure the best corrosion resistance. The carpentry is self-supporting and equipped with removable panels that facilitate the inspection and the maintenance of the internal components. The condesing drain tray is standard on all the units and it is made of stainless steel; the refrigerant gas used is R134A. The refrigerant circuit includes: dehydrating filter, expansion capillary tube and Schrader valves for maintenance and control; the compressor is alternative with thermal relay embedded in the electric windings; the condensing and evaporating coils, as well as the pre and post-heating water coils, are made with copper pipes and aluminium fins. The structure of these exchangers allows low air load losses and therefore the possibility to use low-speed fans with consequent reduction of the noise level of the machine; the supply fan is double-intake centrifugal with forwardcurved blades with three speed directly-coupled motor. The fan, statically and dynamically balanced, is installed on the unit through the interposition of vibration dampers; the nylon air filter is standard and it is detachable in the event of a future waste disposal (class G2); available in 2 sizes (250 m³/h e 450 m³/h), 2 different installation types (horizontal and vertical) and 2 different operating modes (cool air and neutral air). 170

171 Neutral/cool air dehumidifiers All the FH and GH series dehumidifiers can operate without the use of pre and post-cooling water coils. This function is very useful if dehumidification is required during transitional season or if the refrigerator is off. In case of lack of cold water, the outcoming air will be warmer than the air entering the unit. WARNING: The cold air versions can work only if supplied by the system s water (normally provided at a temperature of 15 C). In case of lack of water, the units will be turned off by the safety devices connected to them. 5500GH 5500GHWZ 5500FH 5500FHWZ Neutral/cool air dehumidifiers, flow rate 250 m³/h and 450 m³/h, horizontal false ceiling or vertical wall installation.

173 8.2 CMV DEHUMIDIFIERS Dehumidifiers with air renewal are machines normally inserted in radiant systems to maintain control over the environment relative humidity, at the same time allowing the renewal of exhaust air by means of high efficiency recuperators. The available units are ductable, with wall or false ceiling installation and with nominal air flow rate of 250 m³/h or 500 m³/h. 02GH series units proposed by TIEMME have the following features: The filtering section is incorporated in the machine and the accessibility to the removal of the filter is allowed on the four sides in function of the dehumidifier application; The electric panel is inside and it is accessible removing the side panel: to facilitate the wiring, the electric panel is extractable without removing the fixing screws; The hydraulic connection is characterized by 2 brass unions of 1/2", the water inlet is below near the condensation discharge, while the outlet is above to facilitate the evacuation of air eve through the side vent; According to the flow rate and the temperature of water, the air outlet temperature can be regulated: in rating conditions the output air temperature during dehumidification is about 2 C lower than the room temperature to guarantee neutrality in the supply of sensible heat; The hydraulic circuit is characterized by a heat exchanger and a finned battery that makes a pre-treatment, reducing the sensible heat of the air to be treated, facilitating the dehumidification operation of the evaporator. A valve with electrothermic actuator enables the parallel passage of water on a plate heat exchanger; this allows to transfer the thermal energy of the refrigerating circuit to water, obtaining air treated with temperature lower than the inlet air: this allows to have an integration of sensible heat in the environment; Available of 250 m³/h and 500 m³/h, horizontal installation and two different operating modes (cool and neutral air). 5502GHWZ 5502GHWZV CMV dehumidifier with high-efficiency recuperator and renewal.

174 CMV DEHUMIDIFIERS / EXAMPLES OF OPERATION Toilets on call renewal When the presence sensor placed in the toilets closes the contact, priority is given to the extraction of stale air from those rooms with consequent introduction of clean external air in all the environments. To reduce the energy need necessary to take the external air temperature to the requested conditions, the high efficiency cross-flow heat recuperator pre-treats and reduces the fresh air temperature difference using the stale air energy. The EC low-consumption and high-pressure fan expels the stale and energy exhaust air at the outlet of the heat recuperator. Renewal + Recirculation When the air quality falls below the level of comfort the renewal function is activated where, together with the recirculating air, a portion of clean external air is injected to restore optimal levels of air quality. In this case too, to reduce the energy need necessary to take the external air temperature to the requested conditions, a high efficiency cross-flow heat recuperator is used. This one, using the stale air energy, can expel the stale and energy exhaust air at the outlet of the heat recuperator. Recirculation When the conditions of internal air are qualitatively good but the humidity level is quite high or the external conditions are considerably worse than the internal ones, it is possible to treat recirculating air so that the rooms are comfortable without exceeding the energy demand. If the problem is related to a different temperature distribution in the rooms because of occasional heat sources such as solar radiation, it is possible to activate the system with only ventilation, homogenizing the different rooms. Especially during winter, if it is necessary to integrate or simply speed up the heating of the rooms, it is possible to activate the ventilation in recirculation mode, recirculating hot water in the pre-treatment battery obtaining an integration of sensible heat. During summer, the integration is possible also combined with dehumidification. Freecooling If the temperature of the renewal external air is better than the internal conditions (according to the relative season), a passage is opened and it allows air to bypass the heat recuperator and to get directly in the air treatment zone, reducing the ventilation costs and using the improved characteristics of the external air. In this context, the extraction through the recuperator becomes optional unless specific requirements like those coming from a presence of people in the toilet sensor. Turning the extraction fan off and introducing renewal air, we generate an environment with a slight positive pressure facilitating the release of air from different spots such as doors or hoods in addition to the usual recuperator. 174
