Phil Creaney's ACR Champion

Winner: John Austin-Davies

Picture
 
John Austin-Davies has been at the cutting edge of many significant developments in refrigeration technology over the last four decades.

And despite his official retirement from the Epta Group in September last year, he seems unlikely to sever his links with the industry any time soon…

During his days at George Barker, he developed a number of innovative pack systems and also recognised the need to use HFCs with the lowest GWP at a time when there was little or no understanding of this key measure.

John is a Chartered Engineer and has served as president of the British Refrigeration Association and chairman of FETA. He is also a Fellow of the Institute of Refrigeration, and a Trustee.

In the future, his work to help create the Trailblazer Apprenticeship programme may be viewed as one of his greatest single contributions to the RACHP sector. This is part of an initiative to give the industry the technical support it needs for the future.

IOR immediate past president Steve Gill said: “John’s dedication is driven by his conviction that this will be one of the most important training developments in our industry and will have significant long-term impact and benefits.’’
 

Refrigeration Project

Sponsored by Hitachi

Winner: Star Refrigeration, Snozone

Picture
 
Snozone provides the UK’s leading snow centres for indoor skiing and snowboarding on real snow. The indoor centres, in Milton Keynes and Castleford, offer an authentic slope experience and have taught nearly 2 million guests since opening in 2000.

The Milton Keynes site was operating an R407C chiller system that was unreliable, expensive to run, and difficult to maintain. Snozone could not afford a significant shutdown as this risked melting the ice floor and flooding the inside of the building.

Due to the positive experience of using ammonia at its Castleford facility, it was agreed that this would again provide a future proof, energy efficient solution. Star offered a packaged Azanechiller 2.0 “plug and play” solution that could be installed outside the existing plantroom.

Consultants Hulley & Kirkwood engaged Star Technical Solutions to carry out an Ammonia Hazard Assessment and the customer was able to continue operation as normal throughout the installation.

Energy consumption was a major driver since the existing plant had become so unreliable that hire chillers needed to be brought in for the summer. They were unable to hold temperature and were very expensive to operate. In the first four months of operation, the power associated with refrigeration reduced by 56% compared to the same period in the previous year.

Winner: SCM Frigo CUBO2 Smart Condensing Unit/Beijer Ref

Picture
 
CUBO2 Smart is a range of transcritical R744 condensing units manufactured by SCM Frigo. The range provides an option for small commercial HT and LT systems which traditionally use high GWP HFCs, but where flammable refrigerants are not an easy alternative. 

Up to three evaporators/cabinets can be connected to one unit, making it ideal for convenience stores and small/medium cold rooms. Sites installed to date Heron Foods, Morrisons, Co-op, Sainsbury’s, a cake factory and a boutique hotel.

The unit is simple to install, requiring only suction and liquid interconnecting pipework between the unit and evaporator/cabinet. It incorporates a liquid line filter drier, a suction accumulator, oil return system, over pressure protection and the additional valves required for transcritical operation. The controller is pre set.

The units build on SCM’s experience in the design and manufacture of R744 transcritical packs typically used in large retail applications. This technology has been “downsized” and this allows R744 to be used in convenience store sized systems. In addition, Carel smart control technology ensures high efficiency operation utilising:
  • Inverter driven compressor
  • EC variable speed condenser / gas cooler fan motor
  • Floating suction pressure and head pressure control
  • Electronic expansion valve with variable superheat control
  • Management of the high pressure valve and the receiver pressure regulating valve.

Highly Commended: Star Refrigeration, Azanechiller 2.0

 

Domestic ASHP Project

Sponsored by BITZER UK

Winner: Viessmann and Matrix Energy Systems

Picture
 
The winning installation is part of a prize-winning self-build ‘eco home’ project to be featured on Channel 4’s Grand Designs in 2019.

The client wanted the property – a three-bedroom, detached, two-storey house – to eventually be off-grid, with a flexible heating and hot water system tailored to his family’s needs.

Matrix Energy Systems discussed numerous options with the client. A ground source system was considered but there was insufficient space to lay a horizontal collector and local geological conditions and lack of room for a drilling rig meant a borehole was not an option.

An exceptionally efficient air source solution from Viessmann was eventually chosen because of the ability to integrate controls across photovoltaic (PV) and mechanical ventilation and heat recovery (MVHR) systems and to link in a battery at a later stage if energy monitoring showed it to be beneficial.

The installation is unique because it integrates an air source heat pump with a solar thermal system, a mechanical ventilation heat recovery system and an underfloor heating system.

​All parts are operated with Viessmann controls to provide heating and hot water comfort for the end user at great efficiency, without the need for a complex building management system.

Winner: Toshiba, Super Digital Inverter Smart Cassette

Picture
 
Toshiba’s new Super Digital Inverter “Smart Cassette” claims a new global standard for energy efficiency, low running costs and occupant comfort. It is the highest efficiency product in its class, as measured by Seasonal Energy Efficiency Rating (SEER) for cooling performance and Seasonal Coefficient of Performance (SCOP) for heating. 

A combination of energy-saving technologies and design features contribute to its performance to enable a SEER value in excess of 9 when connected to a Super Digital Inverter outdoor unit: 
  • Improved coil technology
  • A self-cleaning mechanism maintains open airways and surface cleanliness to ensure the energy efficiency of heat exchange is maintained 
  • Air flow across the exchanger is constantly mixed to ensure improved heat transfer rate
  • It uses the latest high efficiency DC fan motor
  • The vent in the cassette has an enlarged opening to allow easier air flow and reduce resistance
  • An automatic occupancy sensor detects when no one is present in the conditioned space, and switches the unit to standby mode or stop, further reducing energy waste

It is suitable for use in retail sites, offices and leisure applications and despite improving airflow by utilising an enhanced air path, noise levels are lower compared with standard cassette systems.

Non-Domestic GSHP Project

Sponsored by ACR Journal

Winner: GS Renewable, Manor Farms R&D

Picture
 
Customer Manor Farms commissioned GS Renewable to measure and investigate heat loss through the concrete floors of its poultry houses and harvest and recycle the heat without causing any litter damage.

Harvested heat would then be stored in a buffer tank and upgraded by heat pumps. When a new batch of day -old chicks arrived, heat would be drawn from the buffer tank and used as a heat source for the heat pumps, which in turn would heat the base slab underfloor heating.

The first stage of the project saw the installation of the UFH in the base pad floor of the new building, creating the different conditions for monitoring. This allowed GS Renewable to simulate the different conditions of existing buildings and see the benefits of insulating the floors. The portable plant room was built off site and transported to the site location in Northern Ireland. 

There was no disruption to the customer because plantroom construction was off site. All monitoring and systems controls were carried out in conjunction with the farmer and to coincide with the batches of birds, and cycles of production.

The customer is amazed by the performance of the system, saying: “The simplicity of operation is amazing considering the complexity of the installation.”

ACR Project

Sponsored by IOR

Winner: Aermec UK, data centre rooftop chiller installation

Picture
 
When one of the of the UK’s top banking and financial companies decided to replace all the chillers at one of its mission critical sites, the key requirements included resilience, energy efficiencies, reduced emissions and lower PUEs (Power Usage Effectiveness).

The cooling system also had to meet the company’s own stringent environmental and sustainable policies.

Five highly efficient 1.366MW Aermec NSM free cooling chillers with screw compressors were specified to provide a robust mechanical cooling solution. The free cooling route offered a greener and more eco-responsible route that would also help boost the data centre’s green credentials. An ice chiller with no free cooling was also included in the specifications.

Each chiller took 12 weeks to design, build and factory test. Each unit measures 13 metres and weighs 11 tonnes. Three chillers are required to run the data centre, but running four is more economical and maximises the benefits of free cooling. The CHW temperature is 13⁰C/19⁰C in normal mode and 17⁰C/23⁰C in high temperature mode to maximise free cooling.

The chillers have saved £50,000 per month – 1,124,028.90 kWh (data collected from September 2016-January 2017). During the three months of November 2016 – January 2017, 100% free cooling was achieved, with no compressors running at all.

Winner: Viessmann and Matrix Energy Systems, Ludford Mill

Picture
 
Ludford Mill is a grade II listed 17th century working water mill on the River Teme at Ludlow, Shropshire. Some of the machinery has been preserved inside the building and it also houses a modern Archimedes’ screw which provides energy for the local community. 

The old gas boiler, which provided heating and hot water, was coming to the end of its useful life and customer wanted a replacement solution that would take advantage of the electricity generated by the Archimedes’ screw in order to reduce environmental impact and save money. 

Matrix Energy Systems chose a Viessmann ground source heat pump to deliver all the heat and hot water required, covering peak heat loss and hot water demand. The Viessmann Vitocal 350-G 27 kW ground source heat pump can operate at up to 70OC and still be more efficient than a gas boiler thanks to its enhanced vapour injection (EVI) refrigerant circuit.

​As Ludlow Mill only requires a flow temperature of 60OC, coupled with the fact that the system’s output is boosted to 34.7kW due to high input temperatures from the river water, it can operate with a seasonal efficiency as high as 5.5. The pump never consumes more than 7 kW of electrical power, therefore ensuring this is a truly carbon negative site.

Winner: Klima-Therm, Althermo DMR-H

Picture
 
The Althermo DMR-H is a new type of hybrid adiabatic dry cooler, designed in the form of a compact cylindrical module. It delivers a new level of energy efficiency and application flexibility thanks to several innovations in components, design and control. 

Due to its cylindrical shape, the exchange surface of the microchannel heat exchanger is 50% greater than units with a traditional configuration and the same footprint. In addition, due to its design, it draws air from all sides with a 360deg catchment. This enables it to be installed very close to walls and other permanent fixtures, reducing the overall installation surface by up to 75%.

It can be used as a single module or multi-plexed to create a compact array, providing high performance, high efficiency cooling up to 2.3MW. It can also be deployed in a closed-circuit, through installation of another plate heat exchanger with a recirculating pump for even greater efficiency.

It is ideal for providing additional cooling in existing data centres, due to its compact footprint and flexible configuration. It can also be used in all commercial and industrial applications where space is limited or obstacles, such as walls or other plant, are an issue for conventional systems.

Roberto Malozzi, managing director of Klima-Therm, said: "We are delighted and honoured to have won this prestigious award against tough competition. It is testament to our staff and supply partners'  hard work, passion and commitment to achieving excellent customer service coupled with our strong focus on innovation and technology.

"The Althermo DMR-H is an exceptional product that really stands out from the crowd. It packs a huge amount of cooling into a very compact space which, combined with its flexibility and modularity, opens up opportunities that would be impossible with conventional cooling plant.

"The future looks bright for Klima-Therm with great opportunities for our technology around the built environment as awareness grows about our systems, which not only keep people comfortable, but also offer outstanding environmental and cost benefits."

Winner: Daikin UK, Altherma 3

Picture
 
Daikin’s Bluevolution technology combines highly efficient compressors with the energy efficient and environmentally friendly refrigerant R32, ensuring the Altherma 3 delivers exceptional performance. 

The Daikin Altherma 3 is available in 4, 6 and 8kW versions. The split wall mounted unit is a flexible system and includes an optional connection to deliver domestic hot water. It can be combined with a separate domestic hot water tank of up to 500 litres, with or without solar support. 

The integrated controller includes the “Daikin Eye’, which constantly displays the status of the unit. Performance of the single fan, low-height outdoor units has been enhanced by increasing the heat exchanger surface area by 9% and by incorporating a new-design fan motor and a hermetically sealed swing compressor. The units also have additional corrosion protection. 

The outdoor units can extract heat from the outside air even when the temperature is -25°C. Systems can deliver temperatures up to 65°C, which means water is stored at 60°C, reducing dependence on direct acting immersion heaters and thus reducing energy costs.

The range is A+++ rated, with a heating efficiency of 5.1 COP at 7 - 35ºC and a DHW efficiency up to COP 3.3 (EN16147. Its weather-dependent set-point controls and inverter compressors maximise the system’s efficiency, ensuring consistent room temperatures.

Winner: JGR Building Services

Picture
 
JGR Building Services chose two HT R744 CUBO2 Smart transcritical condensing units from SCM to trial a non HFC alternative system for convenience/petrol forecourt applications with Lincolnshire Co-op.

The units provide cooling for five 5 Pastor Frigor HT cabinets with MPXPRO controllers and one HT cold room with an 85 bar g LU-VE evaporator on an UltraCella controller.

The cabinets and cold room are fully networked to the units. An RDM controller monitors the cold room and cabinet temperatures and plant fail inputs and is connected to an RDM data manager for local and remote access. 

This is an R744 transcritical solution utilising advanced, complex software which is as simple to install as the traditional HFC units it replaces. The result is a high efficiency, reliable installation.

The potential for leakage for is minimised by rated pressure of 80 bar g on the intermediate and low pressure parts of the system, virtually eliminating the venting of R744 if the system is shut down for any reason, all brazed joints in the construction of the condensing unit (apart from machine-made mechanical joints for transducer connections), and K65 tube and brazed joints for interconnecting.

Energy efficiency is maximised using a Carel control system which accurately matches the unit capacity to the load.
