Summary

The first of 3 project profiles concerns the large-scale refurbishment of a high-rise office building. Step control of chillers reduced power demand. Thermal storage of hot and chilled water to reduce off-peak working. Reflecting glass. Lighting replaced by low-energy fittings and air terminals by VAV diffusers. One plantroom could be removed and used as lettable space. Second is a new Casino complex. Central water chillers with screw compressors on R22. These, and the many cold room systems use water condensing to permit maximum flexibility to minimise lengths of refrigerant piping. The third one is a large factory building, constrained by the presence of internal crane gantries. The structure was well insulated. Summer cooling is by natural circulation ambient air, using controlled roof vents. Winter heating by radiant pipes, using oil as the heat transfer fluid. A.R.T.
