McQuay Complete First Phase of Major A/C Contract
Story
McQuay UK have now completed and delivered the first batch of air conditioning equipment for Derby City General Hospital, which is being redeveloped by Skanska under a £333 million PFI project.
A total of 50 Easdale FP air handling units (ahu) have been supplied, installed and commissioned in the first phase, with air flow rates ranging from 1.17cubic metre per second to 17.36 cubic metre per second. All the systems include heat recovery in the specification, either run-around-coils or plate heat exchangers, together with the standard features of uPVC corner pieces, an extruded anodised aluminium frame and foam filled panels with excellent thermal properties and noise reduction. The units on this phase are serving the Pharmacy, Education, Acute West and the Kings Treatment Centre.
Working along side the ahu’s in this phase are eight McQuay air cooled chillers, including six ALS-E super silent single screw units and two small reciprocating models. All the chillers, which have cooling capacities ranging from190 kW to 950kW, have a tight noise specification of 61dBA at one metre and will operate with environment friendly HFC’s.
The second and final batch of equipment, including 30 ahu’s and two chillers, are due for delivery in Feb 2008. These are for the Acute East building and the refurbished Retained Estate programme.
Jamie Buxton, senior project manager for Skanska commented “From the beginning we worked closely with the project team from McQuay, to design and develop a workable solution for the complex air system at this ‘super hospital’. The first phase equipment is now on-line and so far we are very pleased with the quality and performance of the equipment.”
