itsubishi Electric has launched a viable R32 solution for large-scale air conditioning with the new range of City Multi Hybrid VRF (Variable Refrigerant Flow) products.
The solution was unveiled to journalists recently at Hotel du Vin in
Stratford-upon-Avon which already uses a Hybrid VRF system from Mitsubishi’s range. It brings all of the benefits of VRF air conditioning in R32 format to
deliver a system with a significantly lower global warming potential (GWP) than existing solutions. “There have already been over 500 Hybrid VRF systems installed
across Europe since we launched five years ago and we believe this R32 version will increase the market share for this unique VRF solution,” explains Mark Grayston, product marketing manager for the company’s air conditioning systems. “Not only can Hybrid VRF help remove the need for leak detection,
this R32 version delivers the low GWP benefits that customers are now searching for.” As part of the F-Gas Regulations, the construction industry has
been looking for air conditioning systems that deliver high operational efficiency whilst minimising the global warming potential of the refrigerants used within these systems. Hybrid VRF aims to deliver a familiar, proven solution to offer businesses a commercially viable alternative to R410A systems. Existing VRF units use R410A which has a GWP of 2,088, whilst
the newly adopted refrigerant, R32 has a reduced GWP of 675. Whilst several manufacturers have introduced R32 models in the
room and packaged air conditioning range, this is said to be the first UK model that provides a solution for large VRF systems. “We already have split air conditioning models on R32 and have
introduced Hybrid VRF so that customers have a complete range of R32 solutions regardless of the building or situation,” adds Mark. “Coupled with this is the rapid price rises of R410A month by
month which places a strain on traditional VRF systems so we want to ensure that both customers and installers not only have an alternative, but also get the added benefit of increased performance and advanced controls.” Hybrid VRF is suitable for almost any commercial building and has
already been installed in a variety of applications from offices, hotels, residential accommodation, showrooms, care homes, public houses. “We’ve seen particular growth in Hybrid VRF sales in both the
office and hotel sectors and with this R32 version we have sought to answer one of the hottest topics in the UK air conditioning industry on how to tackle low GWP in larger systems,” adds Grayston. “Hybrid VRF is also designed to offer customers a future-proof solution that delivers advanced efficiency with improved corporate social responsibility.”
UPONOR CELEBRATES CENTURY U July 2018
ponor has celebrated its 100th anniversary, linking up with the Finnish-British Chamber of
Commerce (FBCC) to invite a variety of Finnish business delegates to join the celebrations at its Watford headquarters. After a presentation by UK managing
director, John Fahy, on the company’s heritage, current activities and future plans, the delegates were able to explore the range of heating, cooling and plumbing solutions available from Uponor in the company’s spacious exhibition area, before gathering for the cutting of the birthday cake.
Emma Jalonen from the FBCC said:
“We’re always looking for opportunities for our members to network and to increase visibility for Finnish businesses in the UK so we were delighted when Uponor decided to incorporate its Finnish heritage into its 100th anniversary event. Mr Fahy added: “It’s not every day
you get to celebrate such a momentous anniversary or connect with your heritage and this event has been very special. We’d like to thank the Finnish- British Chamber of Commerce, the Finnish Embassy, Business for Finland and all our delegates.”

hose attending the main venue for this year’s world cup in Russia were kept cool by Gree’s
LHE high efficiency water-cooled screw chiller. The Mordovia competition venue,
located in the city of Saransk, is a new stadium built especially for the 2018 World Cup. The stadium has a standard capacity of 30,000, but was able to house 45,000 during the World Cup tournament. As the air conditioning solution which won a highly contested bidding process, the LHE Series high efficiency water-cooled screw chiller is a large air conditioning unit that was developed by Gree. It uses an advanced semi-hermetic dual-screw compressor, the latest high efficiency heat exchanger, and a new type of optimised power control which together combine to improve operational efficiency and reduce running cost. Its dual-loop
design reduces fault rates, while the dual-compressor design can guarantee normal operation when one compressor is in maintenance. The unit, which uses R134a refrigerant, is grade one for energy efficiency and has a COP of 6.2, all of which helped toward Russia’s declared aim of hosting the most eco-friendly World Cup ever. This is not the first time Gree has been associated with the World Cup. In 2010, Gree was chosen to provide multi VRF units, screw chillers, unitary air conditioners, and air processing terminals for seven large projects for the South African World Cup. Gree UK managing director, Roberto Mallozzi, said: “This shows once again that, while Gree is not as well-known as some other brands in the UK, globally it is a massive player and is well-established as the best selling air conditioning manufacturer in the world.”
