COOLING | NEWS Hunt on for innovative lower GWP technology ASHRAE and UN jointly promoting international award Entries are open for an ASHRAE and UN Environment international award programme to promote innovative designs, research and practices of low global warming potential (GWP) refrigerants and related technologies. The jointly established Lower GWP Refrigeration and Air Conditioning Innovation Award recognises people who have developed or implemented technological concepts applied in developing countries to minimise globalwarming potential through refrigerant management. First place and honorable citation awards will be made in two categories residential applications and commercial/ industrial facilities. The winners will be selected based on innovative solutions for designs, practice or research using lower GWP technologies. The selection will take into account the following criteria: extent of need; innovative aspects in transforming conventional practices; technical replicability to developing countries; andthe economic feasibility to developing countries. Entries will be accepted until 15 May. Winning projects will be publicised by both organisations, and first-place recipients will get a stipend to receive their award at a UN Environment event. ASHRAE President Sheila J Hayter PE said: We look forward to seeing entries from innovators who are committed to sustainability through the development and implementation of a new generation of low GWP efficient solutions.

The chiller uses Carriers PUREtec HFO R-1234ze refrigerant with a global warming potential (GWP) rating of less than 1. Using a fine-control inverter, it matches cooling output with the load, which Carrier says optimises efficiency, particularly at partload conditions. Gatwick Airport is aiming to reduce its carbon emissions by 50% and energy consumption by 20%. The move away fromrefrigerants with high GWP is part of an environmental policy set out in Decade ofChange vision and Cooling Strategy beyond 2020. Trane expands XStream portfolio Mitsubishi Electric to create net zero energy building test facility Mitsubishi Electric is to build a new test facility for its portfolio of technologies for net zero energy buildings (ZEB) at its information technology research and development centre in Kamakura, Japan. The aim is to accelerate the companys development, evaluation and demonstration of ZEB technologies. The four-storey, steel-frame facility, which will cost approximately 3.6bn (25.4m) to build, is scheduled to start operating in June 2020 and will provide 6,000m2 of floor area. It will be used to test applications and innovations in advanced heat insulation, solar shading, high-efficiency equipment, and onsite energy generation systems. Japans Ministry of Economy, Trade and Industry defines ZEBs as buildings with considerably reduced annual energy consumption by saving as much energy as possible via better heat insulation, solar shading, natural energy and high-efficiency equipment. They also create energy for example, with photovoltaic power generation while maintaining comfortable environments. Trane has added new small capacity watercooled chillers and water-to-water heat pumps to its XStream product portfolio. The new XStream RTWF solutions cover lower capacities between 340kW and 920kW and include models designed with low global warming potential (GWP) refrigerants R-513A and R-1234ze. According to Trane, the use of the less than 1 GWP R-1234ze refrigerant makes the XStream RTWF unit capable of delivering heating capacity up to 80C delivering, the company claims, a safe, efficient and sustainable cooling and heating solution. Trane claims the design features of the XStream products make them suitable for critical indoor environments such as data centres, hospitals, large office building or industrial process applications.
