METERING


Sensor-free way to measure residential electricity


Austrian manufacturer EET has announced the launch of its Virtual Meter technology for residential electricity metering. It is designed to measure total household electrical load without relying on conventional current sensors. Originally developed for EET’s own plug-in battery systems, the Virtual Meter technology is now being made available to original equipment manufacturers, metering equipment providers and energy companies, either embedded within their products or as a standalone plug-in meter. The Virtual Meter technology can be


integrated into a range of residential energy products, including plug-in battery storage systems, private electric vehicle charging stations, heat pumps and home energy management systems. It is designed to support applications that require real-time electricity data, such as dynamic load balancing, solar photovoltaic self- consumption and charging based on surplus solar generation.


The technology works by


continuously tracking voltage signatures and neutral shifts created by household electrical loads. It also injects low-level, high-frequency signals into the phase conductor to read device-specific impedance patterns. These inputs are processed using machine-learning models to calculate real-time total home electricity consumption without the use of traditional metering hardware. “The Virtual Meter technology simplifies the metering installation or setup experience, reduces hardware and installation costs, doesn’t suffer from connectivity issues, and reduces post-installation service cases,” says

AIR CONDITIONING PERIMETER COOLING


Updates to cooling for distributed data facilities


The CoolPhase Perimeter PAM air-cooled perimeter cooling range from VERTIV has been expanded with new system ratings and an updated condenser design. The range is intended for use in small, medium and edge data centre environments and forms part of the company’s broader thermal management portfolio. The systems incorporate Vertiv’s


EconoPhase pumped refrigerant economiser, integrated within the CoolPhase Condenser. This design uses a pumped refrigerant circuit to increase the use of free cooling and reduce reliance on traditional compressor operation. According to the manufacturer, this can lower overall energy consumption while supporting reliable and resilient cooling performance. The CoolPhase Perimeter PAM range


uses R-513A refrigerant, which has a lower global warming potential than R-410A and is non-flammable, supporting compliance with current EU F-Gas requirements. Additional features include variable speed compressors, staged coils, integrated control via Vertiv’s monitoring systems and compatibility with remote

management and optimisation tools. “With this latest addition to the


Vertiv CoolPhase Perimeter PAM range, we’re making our direct expansion offering more flexible while addressing two critical challenges faced by data centre operators today: environmental compliance and operational efficiency,” says Sam Bainborough, VP thermal management, EMEA at Vertiv. “The new air-cooled models boost free-cooling capabilities to lower PUE, demonstrating our commitment to providing energy- efficient and environmentally responsible solutions that don’t compromise on


performance.” ■ vertiv.com


Developments in commercial air conditioning systems


MITSUBISHI ELECTRIC has introduced a new range of variable refrigerant flow air conditioning systems under the City Multi R32 YXM name. The range is designed for commercial applications and uses R32 refrigerant. It is available in heat pump and heat recovery configurations, with capacities from 12 to 112 kW. The City Multi R32 YXM range offers


improved performance compared with earlier VRF models, including reductions in running costs and operational carbon, alongside higher energy efficiency. The outdoor units are modular and have a smaller footprint than previous designs, supporting both retrofit and new-build projects. The system can connect up to 50 indoor units to a single outdoor unit and allows multiple outdoor units to be combined for higher capacities. The range incorporates redesigned


heat exchangers, updated defrost technology and a two-pipe configuration. It also includes low-level leak detection equipment compliant


Managing local networks as energy


use changes To support the adoption of low-carbon technologies on traditional electricity networks, UK POWER NETWORKS is trialling a pole-mounted electricity network device designed to improve the use of existing low-voltage infrastructure. The project, known as EcoVAR, is being delivered in partnership with Ecojoule Energy and Fundamentals and is intended to support the growing uptake of low- carbon technologies such as electric vehicles and rooftop solar panels. The trial involves the installation of


five EcoVAR units on existing electricity poles. These devices operate at the low-voltage level, where most homes and small businesses are connected, and are designed to manage how electricity flows across the network’s three phases. In some locations, individual phases can become overloaded while others have spare capacity. Each EcoVAR unit automatically


redistributes electricity between phases to balance demand more evenly. This approach is intended to reduce the need for new cables or other infrastructure


upgrades. The first unit has been installed in Graveney Bridge, Kent, and data from the trial will be used to assess performance across different operating and weather conditions. Luca Grella, head of innovation at UK


Power Networks, says: “Being the first to install this kind of technology in the UK highlights our commitment to working with partners who share our vision for a smarter, more resilient grid. The EcoVAR trial is helping us understand how digital


solutions can deliver real improvements.” ■ www.ukpowernetworks.co.uk


with BS EN 378, remote monitoring capabilities and centralised controls designed to integrate with building management systems. Availability is scheduled from spring 2026. “We’ve worked closely with our


factories to deliver a high-quality product range that’s competitively priced and full of all the design features and flexibility that has made City Multi the market-leading VRF system,” explains Jobin Varghese, VRF Technical Product Manager. “Adding City Multi R32 YXM units to our lineup means we now offer the broadest VRF solution, with the most versatility, scalability, and


quality.” ■ citymultiyxm.com
