SHEFFIELD HALLAM UNIVERSITY CHOOSES RECOOLER FOR REFURBISHMENT PROJECT

When the Building Services Department at Sheffield Hallam University set about refurbishing the newly acquired Arundel Building, it specified a highly efficient ventilation system from Fläkt Woods UK.

Comprising an eQ Air Handling Unit (AHU) and integral ReCooler Heat Pump (HP), the new equipment has replaced the existing natural ventilation setup in order to supply up to 2.5m3/s of conditioned air into a variable air volume (VAV) system. The incorporation of the new ReCooler HP is one of the first inverter driven compressor technology installations of its type in the UK.

Lee Allen, Senior Building Services Manager at the University, is responsible for overseeing the refurbishment. Explaining the project, he said: “The refurbishment has been divided in two phases, with the installation of the ventilation system occurring in phase one. From the outset, we decided to take a new approach, incorporating highly efficient mechanical equipment, alongside cross flow ventilation with new opening windows. This has been designed to allow the centralised ventilation system to be optimised for mixed mode conditions.”

At the heart of the mechanical ventilation system is the Fläkt Woods ReCooler HP unit, which provides heating and cooling from a built-in reversible heat pump and recovery wheel.

Lee continued: “During our initial discussions with Fläkt Woods, we were keen to incorporate the new ReCooler HP unit into the AHU, instead of installing a separate wet heating coil or DX coil. It’s a really neat and tidy package, but also offers COPs that are far higher than the alternatives. The energy saving potential of the device is hugely important in our drive to create a more sustainable estate.”

The ventilation system has been designed so that each floor in the five-storey building is divided into six zones, where the ducting will serve individual VAV boxes with temperature and CO2 control.

The contractor for phase one of the project was Rotherham based Lyndhurst Cooling and Heating Services Ltd. Commenting on Fläkt Woods’ products, Managing Director Russ Oliver, said: “This installation is the first of two projects that we have carried out for Sheffield Hallam University that incorporate the ReCooler HP unit. After using a crane to lift the unit onto the roof of the building, it was successfully connected to the ventilation system without any issues and, so far, we’ve been really impressed with the quality and performance of the equipment.

“We’re also looking forward to evaluating the success of the units over the next year, especially their energy saving potential.”

Phase two of the project – including the design and build of the interior and the connecting of all services – has begun, with the project due for completion in January 2015.

ReCooler HP

The ReCooler HP unit has been cleverly designed to incorporate a reversible heat pump and a recovery wheel to provide a number of key benefits, including: quick and simple installation, extremely high efficiencies and all year round energy recovery.

The unit also utilises a DC inverter scroll compressor, which ensures it achieves a COP up to 6.5, as well as full control of output from 10% to 100%. This allows the Recooler HP to deliver the exact temperature required and maintain occupants’ comfort levels more effectively than traditional fixed speed systems. Plus, the inverter drive allows the unit to work at part load, ensuring the perfect balance between reliability and efficient heating and cooling.

eQ Air Handling Unit

The eQ range of highly efficient AHUs is available in 21 sizes with flow rates from 0.1m3/s to 12.5m3/s – making it suitable for a wide variety of commercial applications, including schools, offices, retail outlets and hospitals. All models incorporate a Centriflow plenum fan with an impeller design to provide the highest efficiencies on the market. In addition, the eQ units are provided with integrated controls, corrosion protection and built-in cooling systems with latent energy recovery.

Fläkt Woods develops, manufactures and distributes ventilation and air climate products, as well as system solutions for commercial and industrial applications.
