Colman & Moducel control environment of grandstand

A wide range of Colman & Moducel equipment plays a key role in the environmental control system for the spectacular new grandstand at York racecourse.

Colman & Moducel control environment of grandstandModucel air handling plant and air conditioning units are being used together with Colman grilles and diffusers in the new Ebor stand – one of the most exciting current developments on the English racing scene.

York is one of the world’s oldest flat racing venues – where the Romans raced horses in 208AD. Every August the modern course is home to the Tote-Ebor meeting, which is highlighted by Europe’s richest handicap event.

The new £20-million Ebor stand – named after Eboracum the Roman City – is a six-storey building designed by architects, The Goddard Wybor Practice, to replace the existing 1965 stand. It provides larger viewing and seating areas together with improved catering, betting and toilet facilities. The Ebor stand also incorporates a number of suites including an Annual Members’ suite.

Air conditioning

Ebor stand at York racecourse chooses Colman and Moducel productsThe Ebor stand is air-conditioned throughout. Air handling power is supplied by 16 Moducel LKS Flexaire air handling units, ranging in capacity from 1.6m³/s to 9.0m³/s.

Flexibility is a keynote of the LKS Flexaire concept. Individual AHUs will be supplied with special purpose modules housing the environmental control equipment required to serve localised areas within the stand. Modules will include direct fired gas heaters – ranging from atmospheric types to forced draught units depending on the size of the air handling unit they serve – run around heat reclaim coils for energy saving, cooling coils and filter sections.

The Flexaire units feature special continuous seam-welded, fully galvanised Pentapost sections for additional strength and durability. Panels are of a ‘sandwich’ construction with a flat inner panel of 1mm galvanised steel and an outer ‘tray’ assembly, also of 1mm galvanised steel, retaining a 40mm layer of high quality infill material with excellent thermal and acoustic insulation properties.

Some of the Moducel units were internally mounted. Units mounted on the roof are supplied in full weatherproof configuration with Plastisol skinned panels inside and out.

Low noise operation

Chilled water is supplied to the cooling coil sections of the air handling plant by 11 Moducel condensing units ranging in cooling output from 35kW to 160kW. The low noise operation of the Moducel range of condensing units, which use R407C refrigerants, feature compact footprints and incorporate scroll type compressors with one, two or four stages of control.

Conditioned air will be distributed from the Moducel air handling plant by supply ductwork and through subsidiary ducts down to the individual areas for delivery into the room space via Colman grilles and diffusers. A wide variety of Colman air terminal devices have been specified for the project to meet the requirements of individual areas within the new Ebor stand. Principal types include both linear slot grilles and swirl diffusers.

The Eaton-Williams range makes it increasingly practical to put together packages of equipment designed to match total system requirements. Single sourcing of air handling plant, air terminal devices, air conditioning units and refrigeration pipework make for an easier interface between manufacturer and contractor. It also gives the entire project team confidence that all individual components are compatible and will perform their function with long-term efficiency and reliability.

Main contractor for the Ebor stand project is Sir Robert McAlpine. Mechanical and electrical consultants are Waterman Gore of Leeds. Exelby Ltd of Leeds is the mechanical and electrical contractor. David Langdon and Everest are the quantity surveyors and White Young Green, structural engineers.
