Ventilation

Importance of Ventilation

Ventilation types considered: Natural Mechanical Mixed Mode

Only occupied rooms were ventilated

Air Conditioning Plant

Air conditioning plant considered: Local Centralised Partially Centralised

Centralised systems considered: Variable Air Volume Displacement Ventilation Constant Volume

Reasons for selection of VAV

Diffusers

Location Suspended Ceiling

Selection Method Room Dimensions Comfort Criteria Flow rate

Swirl Diffusers Uniform air flow

Ducts and Fans

Ducts sized based on flow rateFans sized using index circuit

Equal Pressure Drop methodKitchen and Basement ventilation

Separate extract systemInsulation around ducts

CHP

Sokratherm GG140 Compact CHP UnitRunning from October – April each yearElectrical Savings Versus Grid: €38,500Heating Savings Versus a Boiler: €23,150Payback Period: 5.44

years

Heating Control

Cooling Control

Cooling control similar to heating control, except with chillers instead of the heating supply.

Highest cooling demand shall be catered for.VAV will reduce air supply.Trace Heating.

Energy use is kept to a minimum by use of EC pumps and fans

Transformer Sizing

Max Electrical Load: 650kVATransformer Sized: 800kVA3 Phase Delta/Star ConnectionSiemens GEAFOL: Cast-Resin Insulation

Self Extinguishing Low Maintenance

Summer Design: Worst Case Cooling Design for Coolest Room Ambient Temperature: 34oC

Winter Design: Worst Case Heating Design for Warmest Room Ambient Temperature: -34oC
