Dr. Sergey Karadzhi, Research & Development Engineer, Systemair, writes on the importance of sound in fan development, active sound reduction and what to keep in mind when choosing the best fan for your projects…
There is an urgent need to reduce CO2 emissions and accelerate energy efficiency in the Middle East, with fast-approaching environmental targets looming. As HVAC plays a critical role in meeting these broader objectives, experts reflect on low-hanging fruits that can be tackled and what the region can learn from markets that have adopted more efficient regulations early on.
The GCC region has a long road ahead when it comes to phasing down F-gases in line with the targets set by the Montreal Protocol, largely because of the region’s heavy dependence on the cooling sector. Experts weigh in on the complex issues that exist in the market, what problems must be addressed and what support is needed from manufacturers and governments to support the transition.
The Gulf Standardization Organization (GSO) and Eurovent signed a Memorandum of Understanding during the 5 Years Anniversary Congress of Eurovent’s Middle East chapter. The partnership will bring closer cooperation on standardisation and capacity building and facilitate exchange of expertise between the two organisations.
Harmonics are troublesome for electrical networks as they can cause unreliable operation and overheating as well as requiring expensive oversizing of equipment to handle them. But local energy losses through waste heat are only part of the reason why harmonics are bad for energy efficiency. They also cause a poor power factor that brings down the energy efficiency of the whole network. Frank Taaning Grundholm, Vice President, Global HVACR Sales, ABB Motion, explains why harmonics occur and how active frontend (AFE) drives can eliminate them at source.
Considerable technology advancement in comfort air conditioners designs over the past few decades have seen a substantial development in the variable speed compressor operation (inverter air conditioner). Most of the current international standards allow the intervention when testing these units to provide the setting parameters, while some still forbid it to prevent manufacturer interference.
In January 2017, representatives of 22 HVACR manufacturers established Eurovent Middle East as the region’s first industry association for heating, ventilation, air-conditioning and refrigeration. What started as an initiative to enable more coordination among industry stakeholders has become a real driver for knowledge transfer in energy efficiency and indoor air quality. The occasion calls for an outlook to the next five years at our upcoming event in September.
The event features international and regional experts and leaders from the government and private sector to discuss emerging trends and initiatives in the field of sustainable energy.
On Eurovent Middle East’s 5th anniversary, Markus Lattner, Managing Director, fleshes out the long-term impact of an industry association and reflects on the Association’s early days, the challenges of fostering a spirit of cooperation, and the need to challenge the status quo in the region for the good of the industry.
Eng. Abdesselam Benyaich, Technical Regulations Head, GCC Standardization Organization (GSO), speaks to Eurovent Middle East and provides a comprehensive overview of the regulatory landscape in the region, the need to build bridges through international partnerships, and opportunities for unification to ensure the safety of consumers and sustainability of the member states.
