Bluewater Shopping Centre: Air Handling Unit Modernisation

Project Overview

Service 2 successfully completed a sophisticated HVAC system upgrade at Bluewater Shopping Centre, one of the UK’s premier retail destinations. This project involved converting existing air handling units to modern DX (direct expansion) technology, enhancing energy efficiency and operational reliability while maintaining optimal climate conditions for this high-footfall retail environment.

Challenge

The shopping centre faced several technical challenges with their existing HVAC infrastructure:

        •        Outdated gas-powered air handling system with increasing maintenance requirements

        •        Need to transition to more efficient and environmentally friendly cooling technology

        •        Complex rooftop installation requirements in an active retail environment

        •        Strict operational constraints to maintain shopping centre climate control during works

        •        Limited access windows to minimise disruption to retailers and shoppers

        •        Requirement for safe decommissioning of existing gas and refrigeration systems

Solution

Our team implemented a comprehensive solution to modernise the air handling units:

        •        Conducted detailed site surveys and developed a phased implementation strategy

        •        Safely decommissioned and removed existing gas connections to air handling units

        •        Professionally degassed and removed outdated refrigeration pipework in accordance with F-Gas regulations

        •        Installed new Daikin DX cooling coils on the rooftop location with specialist lifting equipment

        •        Implemented new DX pipework systems connecting to external condensers

        •        Conducted pressure testing and leak detection on all new refrigeration circuits

        •        Completed full system commissioning and operational testing to manufacturer specifications

        •        Provided detailed handover documentation and operational training

Results

The modernised HVAC system has delivered significant benefits to Bluewater Shopping Centre:

        •        Enhanced energy efficiency with state-of-the-art Daikin DX technology

        •        Improved climate control performance throughout connected retail areas

        •        Lower operational costs through more efficient cooling technology

        •        Simplified maintenance requirements with modern, serviceable equipment

        •        Extended system lifespan with current-generation components

        •        Full compliance with current refrigerant regulations and environmental standards

This project showcases our expertise in complex commercial HVAC upgrades, particularly our ability to manage challenging rooftop installations and system transitions in high-profile retail environments with zero tolerance for service interruption.
