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.

UK: Leading temporary cooling and heating specialist, Carrier Rental Systems has secured a contract to supply temporary cooling, heating and ventilation for a high profile film studio project.
A major production company has converted a factory building in London into individual sections to create a film set along with workshops, dressing rooms and a technical centre. Each of the six separate spaces required its own heating, ventilating and air conditioning (HVAC) services to maintain optimum conditions for film crews, performers and technical equipment.
“Because of the age of the building, there was no existing HVAC infrastructure,” said Simon Ward, national events manager, Carrier Rental Systems. “The client asked us to equip the site with high-efficiency temporary HVAC services so it can operate to full, modern standards during the 39-week film production period.”
Carrier Rental Systems supplied rooftop-mounted chillers and indirect fired units for space heating and a 100kW boiler to supply hot water to air handling units. The company, which also installed and commissioned the plant, supplied the building with a number of portable heaters to provide comfort in specific areas.
Due to the importance of maintaining a clean, dust-free atmosphere during construction, porous fabric ducting was used to supply low velocity air in order to avoid entrainment of fine air-borne particles.
Carrier Rental Systems’ solution included a remote control system enabling crew to switch the plant on and off when the stage set is being used. When turned on again after a take, the supply of cool air is instantly restored without noise or vibration affecting production.
USA: Honeywell's new Solstice refrigerant for supermarket refrigeration has been named a finalist for the R&D 100 Awards, sponsored by R&D Magazine.
Often referred to as the "Oscars of Invention," the R&D 100 Awards honors the 100 most innovative technologies and services of the past year. Evaluated with Oak Ridge National Laboratory, Solstice N40 (R-448A) refrigerant replaces high-global-warming refrigerants in supermarket applications. It is part of a growing line of Solstice products for applications ranging from auto air conditioning to highly-energy efficient appliance and building insulation, that have significantly lower global warming potential.
"Naming Solstice N40 a finalist for this award recognizes more than a decade of research and investment that resulted in new solutions to help end customers lower their greenhouse gas impact while complying with new and anticipated regulations," said George Koutsaftes, refrigerants business director for Honeywell Fluorine Products. "In addition to its lower environmental impact, Solstice N40 is highly energy efficient, giving supermarket owners an added benefit."
"This was a particularly strong year for research and development, led by many outstanding technologies that broadened the scope of innovation," said R&D Magazine Editor Lindsay Hock. "We are honored to recognize these products and the project teams behind the design, development, testing, and production of these remarkable innovations and their impact in the field."
Solstice N40 refrigerant, also known as R-448A, has a global warming potential (GWP) that is 68 percent lower than R-404A. In supermarket trials conducted in the U.S. and Europe, Solstice N40 demonstrated at least 3 percent lower energy consumption in low-temperature applications and 5 to 16 percent lower energy consumption in medium-temperature refrigeration compared with R-404A. In R-22 retrofit scenarios, Solstice N40 delivers similar system performance. Whether replacing R-22 or R-404A, Solstice N40 is a near drop-in replacement for supermarkets. Solstice N40 is nonflammable (ASHRAE A1) and non-ozone-depleting.
Global regulators are increasingly moving to phase out high-global-warming refrigerants and, on July 20, the U.S. Environmental Protection Agency published landmark regulations that will phase out the use of many hydrofluorocarbon (HFC) refrigerants. The new regulation, effective July 2016, will require supermarkets, largest consumers of the HFC refrigerant R-404A in the U.S., to discontinue its use as a retrofit refrigerant. R-404A will also not be permitted for use in new supermarkets beginning January 1, 2017.
Solstice N40 was nominated by the publication in the Mechanical Devices/Materials category.
The winners will be announced at a Gala Dinner at Caesars Palace, Las Vegas on November 13.
