Nidec
Nidec Leroy-Somer, a specialist in drive solutions for industrial refrigeration has launched its new Dyneo+ synchronous reluctance PM motor, ranging from 11 to 500 kW, for speeds of up to 4500 rpm. Specially designed for variable speed, this motor off ers an economic and ecological solution for the requirements of industrial refrigeration.
With its IE5 Ultra-Premium effi ciency level, Dyneo+ is said to achieve substantive energy savings in real conditions of use over the course of the cycle, at variable speed and load, as is typical with industrial refrigeration, where needs fl uctuate considerably according to season and production level. Dyneo+ motors are designed to operate exclusively with a variable frequency drive, allowing them to adapt to the speed of the machine being run and improve its performance when operating in overspeed. This provides the benefi t of additional refrigeration capacity for a given device, thereby avoiding having to start up another compressor during a production peak. Moreover, the Dyneo+ solution enables optimisation of the number of compressors for a given installation. Delivering precise speed and torque control in sensorless mode, it guarantees constant torque over extensive speed ranges, with no derating or forced ventilation.

Condair
Humidity specialist, Condair, is releasing a new whitepaper entitled “Making Buildings Healthier”. It contains information on how building managers can protect occupant health with a holistic approach to controlling their indoor environments. The SARS-CoV-2 pandemic has
focused public attention on the risks posed by viral transmission in buildings. Contributory factors that have been known about for some time, have now been placed centre stage, emphasising the infl uence that elements such as fresh air, temperature, minimum relative humidity and even sunlight all have on the spread of viruses.
Samsung
Samsung has launched an air purifi cation panel with PM1.0 Filter for light commercial and commercial spaces. It is a dedicated panel containing pleated air fi lters which are mounted in a Samsung air conditioning system to fi lter pollutants from the air fl ow. It can fi lter dust particles up to 0.3 μm / microns, sterilize certain types of bacteria using an electrostatic charger, providing cleaner air in applications such as offi ce buildings and retail spaces. The panel is available for the Wind- Free 1-Way Cassette, Wind-Free 4-Way Cassette and 360 Cassette as per November 2020.
The panel is equipped with three diff erent fi lters to contribute to cleaner air. The Pre-Filter captures large dust particles, the Deodorization Filter reduces certain unpleasant odors1 and the PM1.0 Filter has an electrostatic charger to capture and sterilize ultra-fi ne dust up to 0.3 μm / microns. The sterilization performance has been validated by British certifi cation expert Intertek2. The research report of Intertek verifi ed that the Filter sterilizes more than 99% of the tested bacteria captured by it.

The aim of Condair’s whitepaper is to provide an overview of these factors and promote dialogue between facility managers, users and health and safety offi cers, enabling the right package of health protection measures to be considered. The whitepaper also includes a checklist so that readers can take stock of their building’s current situation, discover the extent to which their premises protects against the spread of infections and identify where improvements could be made. Oliver Zimmermann, chief executive of Condair Group, commented: “The Condair Group is the world’s leading specialist on humidity control and for years we’ve collaborated with scientists and healthcare experts to understand and promote the importance of optimal humidity for health. Through this research we appreciate that humidity control is just one, but a decisive, weapon that can be used in the fi ght against respiratory infections.”
“Upgrading our built environment to better protect human health from the current COVID-19 and future potential pandemics, whilst not sacrifi cing the important gains we have made in energy effi ciency, is the single largest challenge the HVAC industry will face in our lifetime. To achieve this objective, we must act as a sector to educate, cooperate and implement practical solutions as rapidly as possible. This whitepaper presents a clear and concise overview of the steps building operators can and should be taking to enhance occupant health, using a holistic approach, rather than a one-size-fi ts- all, to indoor environmental management,” Mr Zimmermann concluded.
