Zero heat waste : This is the goal of a dozen European companies and research institutions , including Empa , in the Horizon Europe project HEATWISE . The focus is on buildings with extensive IT loads . All waste heat from these systems |
is to be integrated and utilized in the buildings . Hospitals , universities , research , and office buildings have one thing in common : They are packed with technical devices and IT infrastructure . Operating these |
equipments requires energy – and at the same time generates waste heat that often goes unused . In the Horizon Europe project HEATWISE , twelve research and industry partners from eight countries have joined forces to rethink energy use in buildings with extensive IT loads . “ The goal is a zero waste principle ,” explains Binod Koirala from Empa ’ s Urban Energy Systems lab . “ This means that we want to recover as much waste heat as possible and integrate it into the building ’ s heating system .” The first task of Binod Koirala and his team will therefore be to identify the potential for heat gains using real data from Empa ’ s research building NEST . They will focus not only on the IT infrastructure – from the servers in the basement to the computers |
in the offices – but also on the influence of the presence of people on room temperature and potential heat recovery from this . The aim is to develop predictive control algorithms that link the energy management of the IT infrastructure with building technology and that can also take other aspects into account . “ This includes , for example , the lowest possible CO2 emissions or the most cost-effective operation ,” says Binod Koirala . These multiobjective control algorithms will then be transferred and implemented in four pilot plants as part of HEATWISE : in an IT research and development center in Poland , in buildings at Aalborg University in Denmark , in a car factory in Turkey , and in NEST on the Empa campus in Dübendorf . |
Mitsubishi Electric has launched an air-cooled chiller with a new proprietary single screw compressor to offer greater energy efficiency and high reliability for a longer operating life . The MECH-iF range offers capacities from 345kW to 921kW and is available with R1234ze ( G04 ) or R513A ( G05 ) refrigerant and brand-new proprietary screw variable speed compressors . MECH-iF is a milestone in the company ’ s air-cooled screw chiller portfolio , paving the way for the development and integration of proprietary core technologies . This high efficiency air cooled chiller is the first screw compressor chiller |
to use the new MS variable speed screw compressor with an external inverter , both developed exclusively by Mitsubishi Electric . The MS Compressor is designed with a Symmetrical Compression Load for reduced and balanced loads to ensure a bearing lifetime of over 150,000 hours ( 17.5 years ). All bearings are in low-pressure regions which means they can be lubricated without the need of an oil pump , thus ensuring a better durability of the compressor ’ s operation . Variable Vi technology allows the automatic internal volume ratio adaption by means of the integrated slide valve , ensuring the best efficiency in any working condition , |
and making the MS single screw compressor the ideal solution for any application . In addition , a patented oil return circuit ensures the complete |
lubrication of the bearings , the perfect coupling between the casing and the screw , and total sealing between moving and static parts . |
DuPont has introduced the DuPont™ Pyralux ® ML Series of double-sided metal-clad laminates , a unique addition to |
its extensive family of Pyralux ® laminates for flexible and rigid-flex printed circuit boards ( PCBs ). Developed for optimal |
thermal management , these laminates are an ideal solution for high-reliability markets such as aerospace , defense , electric vehicles ( EV ), artificial intelligence ( AI ) related networking , and other electronic devices . The Pyralux ® ML laminate series provides exceptional performance in challenging environments , making it a versatile and innovative solution for many different applications . Laminates serve as the backbone for complex circuits built on both rigid and flexible substrates . They provide mechanical integrity to flex circuits while allowing designers the freedom to fit circuits into the available footprint . The Pyralux ® ML double-sided metal-clad |
laminates have been engineered to address the challenges of thermal management and provide optimized performance and are ideally suited for flexible printed circuits , sensors , heaters , and thermocouples deployed in highreliability applications that can benefit from unique metals with advanced material performance . Unlike other Pyralux ® products , the Pyralux ® ML laminate contains metal alloy , such as copper-nickel ( CuNi ), featuring Kapton ® all-polyimide dielectric technology . The alloys provide essential thermal resistance for heating , thermal conductivity to improve the desired heat transfer , resistivity for higher heat output , and thermoelectric properties as needed for the application . |
