One example is the Cardiff store, which has a Nordair DF14 air-handling unit serving an Inviron Dirivent ventilation system.
The DF system has an 80/20 air recirculation system and provides up to 80% recirculation of pre-warmed air in winter and 100% fresh air in summer.
The 600 kW unit serves the self-serve and full-serve warehouse sections of the store, which have a total floor area of 7000 m2. It operates to pre-set comfort temperatures during opening hours, with set-back temperatures for restocking after closing time.
