UK: The first UK installation of Rhoss EXP hybrid cooling and heating technology from Klima-Therm has been completed at the new Creative Industries Centre at Kingston College, London.
The three-storey state-of-the art facility is designed to offer outstanding energy efficiency, and houses the college’s programmes in art and design, fashion, photography, music and games design.
The innovative heat pump-based chiller was installed by Lowe & Oliver, and specified by consultant Hamson JPA for its excellent energy efficiency and ability to provide simultaneous chilled water and hot water, linked to whole-building energy harvesting.
Standing for excellence in polyvalent technology, EXP is a new type of hybrid chiller heat pump and heat recovery system that automatically balances simultaneous cooling and heating demands, optimising total energy use and heat recovery within multi-compartmented buildings, to deliver maximum efficiency and occupant comfort.
It is a unique combination of three technologies: a high efficiency heat pump based chiller, an energy recovery system, and a sophisticated control system that regulates and optimises the functioning of the combined system across a building to deliver the lowest possible energy usage while delivering set conditions.
Predicted load profiles for the new college building suggested EXP would provide an ideal solution, given the requirement for simultaneous heating and cooling across the building for much of the year. The unit specified, an EXP TXAETY 2100 with cooling capacity of 105kW and heating capacity of 83kW, has intelligent on-board controls to ensure delivery of heating and cooling to meet the building’s changing demands with little BMS intervention.
The chiller has separate heat exchangers for chilled and hot water production, and unlike other heat pump-based systems these are connected separately to their respective hot and chilled circuits by dedicated pipe work.
Temperature sensors across the relevant evaporator or hot water production heat exchanger enable the chiller to sense changes in cooling and heating requirements. When demand is for cooling only or heating only, the air-cooled condenser section of the chiller is used to reject or absorb heat as required, boosting efficiency and improving overall sytem performance for the comfort of building occupants.
Andrew Latus, who headed the project for Klima-Therm said: “The building design and diverse use lends itself to EXP technology. This, coupled with the requirements for class leading efficiency to meet the building’s green credentials, provided an excellent application for the technology.”
Michael White, who headed up the project for Lowe & Oliver, said: “We have worked with Klima-Therm on previous occasions, and they were able to provide comprehensive technical documentation and proof of performance for the EXP system. EXP provides a good solution in situations where there is a simultaneous demand for cooling and hot water, and particularly in a building where there is significant potential for internal heat recovery.”

UK: Refrigeration specialist, Adande, has announced that the company and its consortium partners is to invest over £4 million in the further development of Aircell technology. Designed to improve the energy efficiency and operational performance of open front, multi deck refrigerated display cabinets.
The investment, funded by equity finance and a £2.1 million AMSCI grant will allow the company and its consortium partners, including refrigerated cabinet manufacturer, The Bond Group, to take the technology to new levels and meet retailers’ specific merchandising requirements in the UK and abroad.
Part of the investment is to go towards the construction of three state-of-the-art test chambers for the research, development and testing of refrigeration systems at the Adande factory in Lowestoft.
In addition to the establishment of the research, development and test chambers, Adande will be creating a dedicated facility, housing CAD resources and a sophisticated computational fluid dynamics’ suite, for the numerical analysis of complex issues, relating to fluid flows and simulation scenarios such as turbulent flows.
Furthermore, the ongoing Aircell development programme will also have positive recruitment implications. It is projected that the establishment of technical and engineering teams, as well as associated management, sales and administrative roles, will lead to 12 new jobs at Adande within the next twelve months, with nearly 100 jobs created by 2024.
How it works
Aircell is a unique and patented airflow management system, which has been designed to improve the energy efficiency and operational performance of open front, refrigerated multi deck retail display cabinets.
It works by dividing the merchandising envelope of the refrigerated display case into separate airflow managed cells with small, low-pressure air columns. Each cell has its own air curtain, which is more efficient than a full height air curtain on a conventional multi deck case. The net result is less pressure on the air curtain of each cell and a substantial reduction in cold air spillage from the case.
Crucially, Aircell does not require back panel flow to support the air curtain, so it does not over cool and freeze food at the rear of the cabinet.
The key benefits of Aircell for the retailer
Adande Managing Director Ian Wood said, “Aircell has been successfully tested under independent laboratory conditions and a pre-production model has undergone live trials.
“Our investment plans and the AMSCI grant will enable us to accelerate the development of the technology to meet the requirements of retailers and original equipment manufacturers, at home and abroad.”

Carrier operates in the UK as Toshiba Carrier UK Ltd and is the world leader in high performance heating, ventilating and air conditioning (HVAC) systems, and is a part of UTC Climate, Controls and Security, a unit of United Technologies Corp. (NYSE: UTX).
UK: Hubbard Products, the world-leading Suffolk refrigeration manufacturer has announced plans that it is to relocate its research, development and manufacturing facilities to a prestigious 50,000 sq ft site at Europark, Ipswich.
After 42 years at its current home in Otley, north of Ipswich the UK’s leading developer of energy efficient, low-carbon refrigeration will be moving its 165 strong workforce in stages from November 2015 to January 2016.
Pat Maughan, Chief Executive Hubbard Products Ltd, said “Our success at developing innovative refrigeration solutions in collaboration with some of the UK’s best-known retailers and developers of zero carbon technology means that we have outgrown the site.
“The new site is well-placed for transport links alongside the A14 for UK wide access and within minutes of the main East Coast container ports that service our increasing export sales to North America, Europe and Asia. The Europark location offers us the opportunity to reorganise and update our future manufacturing systems to suit our growing ambitions and technical requirements. This development will enable us to respond promptly and precisely to the changing needs of the global markets we sell to.”
The company will occupy a group of three units consisting of over 46,500 sq ft of manufacturing and storage facility and an additional 3,000 sq ft of administrative, sales and marketing suites.
The news comes following the announcement of the Dearman Engine Company and Hubbard Products exclusive refrigeration technology partnership.
The development of Hubbard’s Dearman powered nitrogen transport refrigeration system is expected to have a major effect on removing diesel particulates (NOx) from city environments in coming years and is receiving significant global support from policy makers, environmental lobbyists and governments.
UK: Dearman, has renewed its’ technology partnership with Hubbard Products, Europe’s leading designer, manufacturer and supplier of commercial and transport refrigeration equipment.
The partnership will see both companies work together to further develop and bring to market a highly efficient and cost-effective zero-emission transport refrigeration system based around the revolutionary Dearman engine.
The agreement cements their relationship and confirms that both companies will work together, not only to continue to develop the zero-emission transport refrigeration technology, but also to bring it to market internationally.
Pat Maughan, Managing Director of Hubbard Products said: “Revolution is crucial for the future of Transport Refrigeration, for a long while the refrigeration industry has relied on improving old technologies. We believe that approach is a compromise too far and is now irrelevant to the needs of the future. The fresh thinking that Dearman has brought to the table has been revelatory. New ideas create huge opportunities, and the Dearman Hubbard partnership is a chance to create a cost-effective, cleaner and more sustainable environment.”
The Dearman-powered Hubbard transport refrigeration system will build upon on- vehicle trials already conducted by Dearman and extensive lab testing.
The zero emission system eliminates all of the PM and NOx emissions associated with diesel. This is a significant improvement, as existing transport refrigeration units can be up to 29 times more polluting than much larger Euro VI diesel engines.
Commercial trials of the system will begin in the UK later this year, with extended international trials to begin in 2016.
UK: The warm autumn spell could give way to one of the coldest winters for many years, according to forecasters, with a high risk of significant snowfall. Following the warning, temporary heating and cooling specialist Carrier Rental Systems is gearing up to ensure it is able to support customers.
The Met Office says the El Niño effect, a major influence on UK winter weather conditions, will be the strongest since 1950. Scientists warn that conditions could be similar to those in the winter of 2009-10, when heavy snow caused widespread disruption across the country, closing airports and affecting rail and roads. During December 2009, the average UK temperature was 1deg C, the coldest month on record.
In preparation for expected high demand, Carrier Rental Systems has further expanded its heating rental fleet, to ensure it can respond to requests from customers for emergency top-up heating and replacement systems for plant breakdowns during an extended cold snap.
The company has invested in a new fleet of high efficiency boilers, integrated heating packages, fan-powered systems and radiant heaters as part of its plans to support customers this winter. This equipment is now available for hire across the UK and Ireland.
Carrier Rental System’s range includes high efficiency back-up and replacement heating systems
Marc White, Carrier Rental System director, says: “There is concern that the Indian summer may lull people into a false sense of security, and result in buildings and industrial premises being exposed. Forecasters agree that conditions point to a particularly cold winter this year, with a high risk of severe and prolonged snowfall.”
In the event of a sudden arrival of cold conditions, the impact on older heating equipment in particular can be significant, resulting in undiagnosed problems coming to light, as systems attempt to go from standby to maximum output very quickly. This can result in plant failure and create an emergency situation, with implications for building use and company productivity.
Marc White says: “The other issue during extended periods of very cold weather is head-room. Some heating systems in the depths of the 2009/10 winter were unable to cope with the unremitting low temperatures, which for the best part of a month hovered around freezing. Top-up temporary heating can provide the necessary additional capacity to maintain comfort conditions and keep buildings and industrial facilities operating.”
He added: “We have invested significantly in extending our hire fleet, with the addition of new, high efficiency systems. However, equipment availability is finite. Those who secure hire systems early have a vital safety net, and can reassure building occupants and owners that they have the situation covered.”
UK: Klima-Therm and Gree have won a prestigious international award for the world’s first photo-voltaic-powered centrifugal chiller.
The International Achievement of the Year Award 2015 was presented to Klima-Therm’s Roberto Mallozzi and Gree’s Sam Chen at a glittering awards ceremony held at The Hilton on London’s Park Lane, at the recent Cooling Industry Awards.
Harnessing light to power air conditioning is not new. However, the judges said the PV-powered centrifugal chiller represented a breakthrough in terms of the degree of integration required between the PV system and the chiller / heat pump.
The team had to overcome significant technical challenges that have prevented widespread adoption of large PV-based chillers in the past. The machine consists of three main components: the photovoltaic system, an inverter-driven centrifugal chiller, and an integrated power control system.
Crucially, DC power generated by the PV is used directly to drive the chiller, under the management of an on-board power control system. This direct PV power approach increases efficiency by between 6-8 per cent, compared with a conventional grid-connected PV generation plant and air conditioning system.
Roberto Mallozzi said: “It opens the way for the use of PV-powered air conditioning as a mainstream technology. With cooling capacity measured in MW rather than kW, it brings solar-energy powered air conditioning within reach for large or multi-storey buildings with higher cooling demands.
“What is particularly exciting is that it makes possible adoption of PV-powered systems in relatively high northern latitudes, such as the UK.”
He added: “When you consider the number of major buildings planned for construction in London alone over the next five years, not to mention the replacement market for aging centrifugal chillers installed in the Seventies and Eighties, it is not hard to appreciate the enormous potential.
“As part of our armoury of renewable energy solutions, PV-based chillers offer an exceptional opportunity to reduce the industry’s energy use, minimise carbon emissions and dramatically cut running costs for end users.”

UK: A new high efficiency air conditioning system installed at Thorpe Park in Leeds is equipped with Toshiba’s new generation of touch-screen Smart Touch controllers.
The state-of-the-art interface gives engineers and building managers immediate access to system controls, set points and a comprehensive range of diagnostic and analytical tools, via a full-colour high definition screen.
The open-plan building is cooled and heated by a Toshiba SHRM-i three-pipe heat recovery VRF system, with a two-pipe SMMS-i VRF heat pump system serving separate administration areas.
The system, supplied by Cool Designs Ltd and installed by HLA Services, has five outdoor condensing units with 47 mainly ducted indoor units delivering up to 416kW of cooling capacity.
It replaces an aging chilled water-based system that was struggling to maintain conditions, given high heat loads and solar gain to the building.
A key element of the design brief was a requirement to deliver high quality, stable comfort conditions for building occupants. The project was made more challenging by the nature of the open-plan, multi-storey work space, which has a high central atrium.
Cool Designs worked closely with HLA to produce detailed heat load calculations for the building, and then created a system design using Toshiba’s new pipework and wiring software package.
Chris Oldroyd, who headed the project for CDL, said: “The design plays to the respective strengths of the Toshiba VRF heat pump and heat recovery systems, making the most of the opportunity for heat recovery in order to reduce running costs and carbon emissions.”
Paul Smith, who headed the project for HLA Services, said: “CDL’s Toshiba-based design provided a flexible, high quality and efficient solution, with the new Toshiba Smart Touch Controller interface enabling quick access to set up the system, and monitor and control it once commissioned.”
UK: Mitsubishi Electric has introduced a new replacement grille for air conditioning units, which automatically lowers the grille on any ceiling mounted cassette up to 4 metres high. Meaning that filters can be cleaned by non-skilled workers to reduce maintenance costs and improves health and safety by removing the need for ladders or towers.
According to the Health & Safety Executive over half a million working days were lost in 2014 due to falls from heights so finding ways to reduce risk is important for everyone.
The PLP-6BAJ grille is easy to fit as a replacement for any of Mitsubishi Electric’s PLA, or standard size PLFY models of 4 way blow cassettes.
Watch this short video demonstrating how the system works.
The grille is available immediately and can be controlled from a PAR31 controller or the remote control that comes with the grille. It is straightforward to use and includes an automatic lowering function to simplify filter maintenance and help maintain energy efficiency.
Keeping the filters clean saves on energy use and reduces the stains and smudges on ceiling tiles caused when filters become dirty.
