ShareEco-friendly cooling for Tokyo’s Haneda Airport
The new international terminal of Haneda Airport opened in October 2010. It uses a combination of geothermal energy, solar power and cogeneration systems to reduce energy consumption and is also the first airport to use sodium sulphur (NaS) batteries capable of large-capacity energy storage.
The new terminal’s air-conditioning system three 1000-RT centrifugal HFC245fa chillers, one of which is an inverter type; two absorption chiller-heaters totalling 2200 RT, and air and water-source heat pump systems for individual air-conditioning systems. The chillers have a COP of 6 or more and the inverter-type chiller features high-cycle efficiency and excellent part-load performance: at a 40% load, the unit demonstrates a COP of 16.5 (14°C cooling water).
