J&E Hall brings energy efficiency to Liverpool University
T
he pressure is on facilities managers and maintenance engineers to find new ways of keeping commercial building interiors and equipment cool. The public sector is not immune to these pressures; hospitals and universities are having to rethink how they handle this side of building maintenance. A cooling upgrade at the University of Liverpool Human Anatomy Resource Centre highlights this change. The work carried out at the University’s HARC Sherrington building focusses on the mortuary where the former eight-chamber facility was replaced by a newly- built dual compartment room with chill space operating at +4°C and a freezer space section at -21°C.
J&E Hall Fusion Commercial Condensing Units were installed by RSM Air Conditioning and Refrigeration, of Bootle, Merseyside, while sub-contractors G and L Cold Store Construction of St Helens built the new coldrooms. The work included the installation of new racking systems to enable the storage capacity to be increased. The Fusion and Fusion Scroll range units were supplied by FSW of Preston. Two JEHR-0067- B1-M-1 units were installed in the chill room and two JEHS-0200-B2-L-3 units in the freezer room. The systems run on R407F, a low GWP alternative to R404A and R22, which meets the
requirements of the F-Gas Regulations. The move from high GWP gases in refrigeration and air conditioning systems is well under way. The EU’s F-Gas emissions will be cut by two-thirds by 2030 – compared with 2014 levels. A reminder of the consequences of ignoring the F-Gas Regulations has been issued by the Government. From April 1, those who breach the F-Gas Regulations in England and Scotland can face fines of up to £200,000. The onus is on the refrigeration and maintenance industry to rise to the challenge as it looks to reduce our reliance on the gases that harm the planet. RSM Air Conditioning and Refrigeration director Gordon Moon said: “We chose J&E Hall units for their ease of installation, reliability and ease of access during maintenance. They are also very quiet.
“Much of our work is concentrated on the NHS, local authorities, police, fire, ambulance and schools. We look after 15 hospitals, so we do a lot of mortuary work. We have been maintaining the existing plant at the Human Anatomy Resource Centre for more than 20 years.”
Fusion and Fusion Scroll commercial refrigeration units create the perfect answer for those demanding a compact yet efficient unit. They are the ideal solution for commercial
refrigeration sectors where noise, size and reliability are paramount.
In a cabinet made of electro-galvanised mild steel with an anti-corrosion treatment and coated in baked polyester powder paint, the units are able to withstand the most stringent weather testing. The integral IP54 rated control panel provides further protection to all essential electrical components. All units are acoustically lined.
Other benefits to the installer include hinged doors that provide simple access for service and maintenance, 100 per cent tax relief via the Enhanced Capital Allowance for medium temperature scroll models and a three-year manufacturer’s warranty on all units. “The work at the university involved stripping the cold rooms back to the building fabric,” said Mr Moon. “We degassed and removed the existing refrigeration plant, leaving a bare cold store. We installed the Halls’ units on the roof, two floors above the cold store on the sixth floor of the building. The existing bank of units was at the end of its life and we were tasked with replacing them. It was down to us which equipment was chosen. I specifically like the J & E Hall range of Fusion units. We have used a lot of them over the years.”
The centre’s technical manager Lynne Staunton-Jones said that as the mortuary area needed refurbishing, it was decided to reconfigure the layout while installing modern, more efficient units. She explained: “Instead of having multiple units which were old and prone to failure, RSM Air Conditioning and Refrigeration recommended that we went for two units per fridge.
“We found the need to accept more cadaveric material after we took part in a documentary Body Donors – Life After Death on Channel 5. We had more inquiries and more people wanting to leave their bodies to the university. The documentary followed the journeys of two people who courageously decided to donate their bodies to medical science.”
The new systems are in place with a low GWP refrigerant employed, Ms Staunton-Jones said: “We believe that we have future-proofed things as far as is possible. We are very happy with the work completed.”
