Timescale 6 months

OBJECTIVES

To develop a strategy to replace the existing ventilation 11№ air handling
units with 2№ units. These units incorporated a duty/standby fan
arrangement to ensure security of supply in the event of a fan failure. The
temperature control of the ventilation to the various areas was by terminal
Variable Air Volume dampers that operate on the dictates of the fume
cupboard extract units.

In addition space planning was critical as the existing installation did not allow
suitable space for servicing and maintenance

DESIGN

The project included for the provision of new more efficient replacement air
handling equipment to provide fresh air to the existing laboratory building.
New terminal VAV dampers within weatherproof enclosures where provided
at roof level to provide supply air make-up ventilation throughout the
building. New Low Temperature Hot Water (LTHW) heating distribution was
provided to serve air handling equipment frost coils and the terminal reheater
batteries.  New heat reclaim circuits were also provided.

OBJECTIVES

Arrange access to site. Replace the obsolete Eltek SMPS175 DC Power Systems with the new Emerson Netsure 211 DC Power System. Transfer all the tele-communications circuits and batteries from the Eltek system to the Emerson system without any loss of service to customers. Commission systems and complete an alarm test and cabinet inventory on completion

SPECIFIC DESIGN REQUIREMENTS

Due to the phasing (the existing plant was to remain operational until changeover
to the new plant) an extension of the existing ventilation  louvered plant screen was required. This enabled the new plant to be installed whilst the old plant was still operational and maintaining space conditions within the laboratories.
