VRF systems have seen high sales growth, says Daikin

Michel Farah, director of corporate environmental and social responsibility, Daikin Middle East and Africa, talks about how Variable Refrigerant Flow (VRF) systems have seen high sales growth for the past five years.
"If we measure by demand or by market growth, VRF systems have seen the highest sales growth rates when compared to other DX or chilled water product groups. The market has grown from 5,000 systems to around 25,000 systems per year during the past five years with an exceptionally high rate during the past three years according to JARN (Japan Air Conditioning , Heating and Refrigeration News)," Farah told MEP Middle East.
Farah says that the VRF market growth has taken a share from the conventional systems across the GCC markets favoured by the increased need for energy-efficient HVAC systems, particularly by the government-led urban residential developments.
"In the past 10 years, we have witnessed the increase in the field-installed Variable Frequency Drives in large installations which help optimise the energy use of the HVAC system components. Today, VRF brings the concept of variable speed on all moving components as a standard product that delivers high levels of energy efficiency breaking the 1 kW/tonne barrier which used to be exclusive to water-cooled systems," Farah adds.
According to Farah, some of the market drivers for efficient HVAC systems are energy efficiency regulations, green projects and a rising trend for energy prices. He says: "The initial cost selection will never disappear but it is happening on a higher efficiency level for the benefit of a lower life cycle cost incurred by the owner or the end user."
Daikin recently launched the next generation of premium efficiency air cooled screw chillers EWAD-MZ series, at an event in Dubai.
Farah's views 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.
