2 Micronal ® PCM Intelligent Temperature Management for BuildingsMicronal ® PCMIntelligent Temperature Managementfor BuildingsThe Challenge:The indoor temperature is signifi cantly infl uenced by thethermal behaviour of a building. In buildings, which becauseof their construction method lack the required thermalstorage mass, inner loads and sun radiation lead to greatfl uctuations in temperature, losses of comfort and increasedneed for air conditioning inside buildings.Nowadays, construction of offi ces and housing is increasinglycarried out using modern lightweight building methodsof wood and steel designs with highly insulating wall constructionmaterials and large glass surfaces. The highdegree of prefabrication and the avoidance of long dryingtimes lead to quick progress in construction and thus anespecially high level of effi ciency. In striving to optimise themass and dematerialisation of the building components, inaddition to various practical and economic advantages, oneproblem, namely a loss of thermal mass and the negativeimpacts on the indoor climate arises.Micronal ® PCM – Future built inCompliance with the relevant construction guidelines governing climate policy, along with international efforts in buildingcertifi cation in terms of indoor climate, comfort, health, use of resources and energy effi ciency, make clear the highdemands on architecture, building planning and construction. The consequence – the necessity of developing new,innovative and sustainable approaches for the construction industry, in order to deal with these challenges and to fulfi lthe exacting demands. With Micronal ® PCM BASF has developed an innovative latent heat storage material, whichmakes the construction industry sustainable in the area of air conditioning in buildings. Micronal ® PCM is an innovative,long-term and sustainable solution for a pleasant, healthy indoor climate and more energy effi cient air conditioning; formodern architecture with high demands – today and in the future.

Integrated into variouskinds of building materials and building systems, Micronal ®PCM contributes to an improved indoor climate, more comfortableliving conditions and better energy effi ciency, usingintelligent temperature management.Temperature management in thedefined comfort zoneDayTemperatureNightTime/days 1 2 3 4withoutMicronal ® PCMwithMicronal ® PCMcomfort zoneAdvantages of Micronal ® PCM at a GlanceOptimum indoor climate und consistent temperatures throughout the yearWorking and living in a comfortable and healthy temperature zone, that is between 21°C and 26°CA bonus for health: quiet air conditioning without the occurrence of draughts and transference of noiseGreater energy efficiency through better energy management.

4 Micronal ® PCM Intelligent Temperature Management for BuildingsMicronal ® PCM – High Tech in MicrocapsulesMicronal ® PCM is a phase change material, which completesa phase change from solid to liquid within the indoortemperature and human comfort range, i.e. at 21°C, 23°Cor 26°C and in doing so can store a large quantity of heat.This principle of latent heat storage is comparable to an icecube, which during its melting process keeps a drink at aconstant temperature of 0°C. Micronal ® PCM uses this simplephysical effect to achieve the objective of stabilising indoortemperature.Micronal ® contains in the core of the microcapsule (sizearound 5 μm) a latent heat storage material made from aspecial wax mixture. When there is a rise in temperatureabove a defi ned temperature threshold (21°C, 23°C or26°C), this absorbs the excessive heat energy and storesit in phase change. When the temperature falls below thetemperature threshold, the capsule releases this stored heatenergy again. 1TEMPERATUREPhase Change inside the CapsulesolidPolymer5 μmTm:21/23/26 ˚CliquidWaxMELTING/SOLIDIFICATIONENERGY ABSORPTION/ENERGY RELEASEsolidWhilst the latent heat is generally stored autonomouslyabove a defi ned temperature from heat inputs occurringduring the day, discharge of the storage material canoccur via natural ventilation, mechanical ventilation oralso via sustainable or conventional cooling concepts.COOL HOT COOLSURROUNDINGSThe Advantages of MicroencapsulationSealed packaging, the product always stays dryThe phase change is not visible externally, the change in volume in the melting process occurs in each capsule.PCM building materials therefore remain stable in terms of size.Tiny volumes and tiny space requirements with high heat storage capacity.“Just in Time”. Rapid heat exchange through high surface / volume ratio. 1g Micronal ® PCM = 30m² surfaceCan be directly integrated into the building material, i.e. can be used without additional work processes orhigher complexity on the construction siteMechanically, practically indestructible, high cycle resistance and functions over decadesFormaldehyde-free1With this process, the aggregate state of the storage material changes: the temperature of the system therefore remains almost constant,as long as the whole concealed = latent heat is absorbed or released.

5 Micronal ® PCM Intelligent Temperature Management for BuildingsThe Micronal ® PCM Product PortfolioMicronal ® PCM can be incorporated into building materialsin different forms. For all applications in which a liquid formcan be used, BASF offers Micronal ® PCM dispersions, inwhich the microcapsules are dispersed in water. For buildingapplications which require a powder form (such as dryblends like plaster or cement mortar for example), BASFoffers a portfolio of redispersible powders.Micronal ® PCM – as dispersion and powderProductdesignationProducttypeMelting pointapprox.ApplicationIntegrationrangeOverall storagecapacity approx.Latent heat capacityapprox.SolidcontentDensityApparentdensityViscosityDS 5000 Dispersion 26°C Summertime excessive heating protection 10–30˚C 59 kJ/kg 45 kJ/kg Approx 42% Approx0,98Approx200–600 mPasDS 5007 Dispersion 23°CStabilisation of the indoor temperaturein the comfort zonePassive and active application10–30˚C 55 kJ/kg 41 kJ/kg Approx 42% Approx0,98Approx200–600 mPasDS 5030 Dispersion 21°C Surface cooling systems 10–30˚C 51 kJ/kg 37 kJ/kg Approx 42% Approx0,98Approx200–600 mPasDS 5001 Pulver 26°C Summertime excessive heating protection 10–30˚C 145 kJ/kg 110 kJ/kgIn powderformApprox250–350 kg/m 3DS 5008 Pulver 23°CStabilisation of the indoor temperaturein the comfort zonePassive and active application10–30˚C 135 kJ/kg 100 kJ/kgIn powderformApprox250–350 kg/m 3DS 5029 Pulver 21°C Surface cooling systems 10–30˚C 125 kJ/kg 90 kJ/kgIn powderformApprox250–350 kg/m 3Best results can be achieved with Micronal ® PCM latent heat storers with regard to passive overheating protection,stabilisation of indoor temperatures and effi cient use of surface cooling systems, as a component part of a functionalbuilding concept.The Right Choice of Melting PointDid you know:30 kg of Micronal ® PCM gives around1 kWh of storage performance.

The heatcapacity of a wall construction, twice equiped with 15mmPCM SmartBoard ® , is thus comparable to a 14 cm thickconcrete wall or a 36,5 cm thick brick wall.Ilkazell Isoliertechnik GmbH’s Ilkatherm ® SystemDerived from sandwich technology (metal surface, PURrigid foam core, metal surface), highly effi cient radiantceiling panels with Micronal ® PCM were developed, whichcan be linked to existing cooling water circuits via a simplePlug and Play process. Water cooling is achieved throughcapillary tube mats, which are located on the reverse ofthe PCM layer facing into the room. This system solutionmakes renewable cooling and buffering of peak loadspossible .© Ilkazell Isoliertechnik GmbHPassive or Active ApplicationWith Micronal ® PCM, modifi ed building materials can be used in “passive application”, i.e. without simultaneous useof mechanical cooling, but also as a component of an “activated” system in building concepts. An activated systemdescribes the combination of various components, which enable recooling or active charging or discharging of thestorage material. The heat transfer medium for this can for example be air or water.
