Uniflair - Case Studies

M25 Disaster

M25 Disaster Recovery Site

Problem: The disaster recovery centre rarely utilised the 800kW cooling chillers leading to maintenance and reliability problems from operating below the minimum load requirements.

Solution: A 2500 litre buffer tank and a 150kW Uniflair packaged free-cooling chiller were installed, which were more suitably sized for the centre's base load. The results show a 34% daily energy saving, equating to an annual saving of over £22,000.

Holborn's Data Centre Upgrade

Uniflair's installation partner, Holborn, embarked on a 13 month project to upgrade the air conditioning to 2 data centres to help them achieve Tier 3 classification.

Highlights of the project include:

  • Airflow direction reversed to deliver cool air through floor grilles
  • Uniflair CRAC units used then air handling units (AHU) re-configured
  • Data centre remained working throughout
  • Installation of 7 ‘DX’ cooling system units
  • Installed, tested and commissioned in accordance with CIBSE

Upgraded AC to Data Centre’s Critical Power Facility

In order to upgrade the classification of the client's data centres, a new battery back-up was to be installed to enhance the existing uninterruptable power supply (UPS). As well as: Data Centre AC

  • a cooling provision upgrade for UPS
  • building 2 battery rooms
  • air conditioning made more energy efficient
  • automatic control system & BMS modifications

Replacing Business-Critical AC

Holborn decided to supply the data hall with temporary air conditioning while work was done, enabling no vital business functions to be lost. The existing room performance was recorded so the temporary cooling solution replicated the existing environment.

Project Highlights:

  • 48-hour data hall temperature analysis
  • External run & standby chillers specified
  • BMS-incorporated temporary system to integrate with site systems
  • Security, IT equipment, fire detection and suppression systems covered
