Expert: VRF technology has become increasingly popular

Peck Zhao, marketing manager at Midea Commercial Air Conditioner, told MEP Middle East that over the past 10 to 20 years, VRF technology has become increasingly popular in Europe, Asia and now in the Middle East.
Zhao shared an example: “The extraordinary Al Ain 5000 Villas project sets a very good example of VRF installations. This sophisticated new VRF HVAC technology is capable of providing not only cooling, but also heat, and even both simultaneously to different areas within the space.
These VRF systems are very quiet and energy-efficient because the variable-speed compressor runs only at the capacity needed for the current conditions by varying the flow of refrigerant to the indoor units based on the exact demands of the individual areas.
For example, Midea recently launched its new generation full DC inverter V6 series VRF system in Dubai, featuring the world’s largest capacity single module outdoor unit at 38HP and combination capacity at 128HP, as well enjoys a 40% reduction in footprint."
In the HVAC industry, Zhao said, energy conservation and restricting the use of hydrofluorocarbons (HFCs) with high global warming potentials (GWPs) are the current major issues for HVAC equipment.
To improve the overall energy efficiency in chiller systems, there is more focus on larger oil-free centrifugal compressors with permanent magnet (PM) motors, variable speed control by Variable Frequency Drives (VFDs) and two-stage compression systems that maintain high efficiency with wide operating ranges, Zhao said.
Zhao's complete interview will appear in the 1208 issue of MEP Middle East's special report on energy-efficient HVAC systems, which will be out on the first week of August 2017.
