Dubai, UAE, 18 February 2018: Carrier Middle East launched a new range of variable refrigerant flow (VRF) systems and chillers at a February 15 technical seminar in Dubai.

Highlighting the key features of the VRF system, Eve Lecerf, Senior Sales Engineering Manager, Sales Engineering, TOSHIBA Carrier (Thailand), said, “The Xpower VRF system is built in with a twin-inverter rotary compressor technology and is suited for high-ambient temperatures of up to 46 degrees C.”

Lecerf added that the inverter compressors provide accurate capacity management, which is a requirement for back-load efficiency, and they use less oil. She further said a dual-vane feature minimises pressure losses between high- and low-pressure chambers, increasing system efficiency, while also enhancing the reliability of the compressors.

Elaborating on the twin-rotary compressors, Lecerf said, they allow “the system to respond precisely to the capacity needs of the end user while minimising energy losses”.

Speaking on other features, such as the piping, Lecerf said, “Considering that you have tall towers in UAE, the piping for this system can extend up to a maximum length of 1,000 metres.”

She added that the systems are available in four different ranges, which include a mini VRF.

For the Saudi Arabian market, Lecerf added, owing to the power difference in Saudi Arabia, Carrier has a unique range for the Kingdom, which is 60Hz, while the rest of the Middle East, including UAE, is 50Hz. “The units designed for Saudi are certified by the Saudi Standards, Metrology and Quality Organization (SASO),” she said.

Speaking on the new chillers, Rajesh Malik, Country Products & Solutions Manager (Commercial, Residential and Aftermarket-UAE), UTS Carrier, said: “We are all excited to launch the new range of AquaForce Vision 30KAV chillers with Greenspeed Intelligence. These units are designed to surpass regulation requirements regarding energy efficiency and acoustics levels.”

Highlighting some key features of the chiller, Malik said the product has a resonator integrated into the compressor, which reduces the sound significantly.

Further elaborating on the acoustics aspect of the chiller, Malik said, “The volume control combines with the function of the variable-frequency drive (VFD), which gives the user precise control of the load.”

Speaking on the VFDs, Malik said Carrier is introducing air-cooled VFDs that neither require any liquid chilling nor need to be connected to the fluid chilling system. “The benefit of the VFDs is that they do not require a lot of maintenance when you are looking for a failure of the pumps, condensation issues and filling of chilling systems, and there is no capacity drop,” he said.

Faisal Malik, Head of Marketing Operations, Carrier Middle East, said, “The purpose of today’s forum was to connect with the HVAC professional community across the UAE and showcase to them what we plan to introduce in 2018.”

Speaking on the penetration of VRF, Malik added that the growth pattern of the technology has been going up, as consultants begin to understand the benefits of the technology, which makes the future for VRF look optimistic.
