Bitzer has announced details of a new high-efficiency scroll compressor for air conditioning and HVAC applications.
At last month's Mostra Convego exhibition, Bitzer showcase the new Orbit+ models based on Bitzer’s currently available Orbit 6 and 8 series. These new units are equipped with a line start permanent magnet motor and improve the seasonal performance (SEER/IPLV) by up to 8% while also increasing cooling capacity by up to 5%.
The Orbit+ compressors can replace or be combined with standard Orbit models without redesigning the system significantly. The tandem and trio combinations are easily tailored towards system capacity and efficiency targets according to annual load characteristics and the customers’ specific needs. For even better capacity modulation, customers can add a frequency inverter like the Bitzer Varipack.
The Bitzer Orbit models recently introduced low-GWP A2L refrigerants, such as R454B and R452B and are designed to work with R410A. Similar to the Orbit 6 and 8 series that have already been introduced, the new Orbit+ models are able to operate with a frequency inverter at 35 to 75Hz while performing with a low sound level and low oil carry-over rate.
The compressors are interchangeable, which Bitzer says allows systems designers and manufacturers to simplify development work by using existing frameworks, footprints, piping layouts and manufacturing processes.
Bitzer has said they are easy to install, offer high energy efficiency when fully or partially loaded and have the lowest noise emissions in their capacity class. Energy consumption is extremely low, especially at low condensing temperatures, says Bitzer, where the Orbit Boreal series can be applied.
Beijer Ref's net sales have been boosted by 8.5% in Q4 of 2016 due to contributions from the newly acquired UK based wholesaler HRP and by the Australian company Realcold.
The Swedish refrigeration and air conditioning wholesaling group maintains that the key to its rise in sales to SEK2, 199m (€232m) in the forth quarter was certainly influenced by a good performance in Central Europe, which in no small part was the contribution of the integration and turnaround of the previously loss making HRP.
CHILE: Beijer Ref’s Italian manufacturing subsidiary SCM Frigo has supplied the equipment for Chile’s first ever transcritical CO2 supermarket refrigeration system.
The 5,300m² Jumbo store in Chile’s southern city of Valdivia, which opened its doors on January 12, has become a showcase for sustainability. In addition to the incorporation of Chile’s first transcritical CO2 system, the store uses LED lighting throughout and includes a BMS systems for the intelligent control of all building system.
The project was implemented by the Ministry of Environment’s Ozone Unit and was funded by the Climate and Clean Air Coalition (CCAC) and support from the United Nations Development Programme (UNDP).
The two SCM Frigo units, are designed for a total capacity of almost 400kW for medium temperature refrigeration and 100kW for the low-temperature requirement. They serve a total of 115 MT/LT cabinets and 30 cold rooms.
Hailing the installation as an opportunity to promote the technology in the country, Claudia Paratori, coordinator of the Ozone Unit said: “This project will connect the different actors in the cold chain supermarket sector and promote the adoption of this technology and help minimise the introduction of HFC-based systems in Chile.”
The project aims to highlight ways to reduce greenhouse gas emissions and introduce environmentally friendly technology. It also has economic benefits with approximately 20% in energy savings.
“After the adoption of the Kigali Amendment and the entry into force of the Paris agreement, nations and the industry must move quickly to seize the immediate opportunities at hand to avoid the growth of HFCs and realise energy efficiency gains of technology change in the refrigeration sector,” added Jacques Van Engel, director of the Montreal Protocol/Chemicals Unit, UNDP.
“Since sustainability is our challenge, we are proud to be part of this team contributing to the goal,” said SCM Frigo managing director Nicola Pignatelli.
Established in 1979, SCM Frigo became a wholly-owned subsidiary of Beijer Ref in 2014.
Germany. The compressor specialist BITZER has made operating its BITZER Electronics Service Tool (BEST) even easier: users can now watch a video explaining how to use the tool on the BITZER website and on the video platform YouTube. Refrigeration and service engineers can quickly and easily operate all BITZER IQ products from their PC using the BEST software.
In the almost five-minute-long video, an English-speaking narrator explains the tool and its most important functions. The software provides users with a complete overview of the operating status, troubleshooting and maintenance of BITZER products. BEST makes service engineers’ work much easier: for example, they can use it to quickly and safely set device parameters, analyse errors or download and save data logs.
The software supports VARISPEED reciprocating compressors, CSV compact screw compressors, the ECOSTAR condensing units LHV5E and LHV7E, as well as the protection, monitoring and control devices SE-i1 and CM-RC-01.
The BITZER Group is the world’s largest independent manufacturer of refrigeration compressors with sales companies and production sites for reciprocating, screw, and scroll compressors as well as pressure vessels all over the globe. In 2014, 3,400 employees generated sales of €657 million.
PRODUCTS: Less than a year after its launch, a new transactional website enabling engineers to purchase chiller spares online has proved to be a multi-million-pound success for Johnson Controls.
The EasyParts website enables engineers to purchase major spare parts such as compressor rotors, valves and motors online. Top selling items like oil filters, sensors and chiller safety devices are all easily accessible.
John Pritchard, Parts Director HVAC & R said: “The aim in setting up the service was simple - to make it as easy as possible for engineers and maintenance companies to order genuine replacement parts for York brand chillers online. It has worked incredibly well, and we are pleased with the rapid take-up.”
For engineers, there are several benefits of ordering online. The site gives 24/7 access to spares with expedited delivery, important in situations where plant has suffered a breakdown. Orders placed before 2.30pm can be delivered next day.
Users can see real-time stock levels for replacement components, and the
current status of orders, enabling engineers to track deliveries. It also provides access to order history and associated paperwork, such as invoices.
Importantly, the site uses photographs of spares to provide visual confirmation of the relevant part. It includes pictures for most of the company’s 15,000 active lines of stock.
“We wanted to create an Amazon-type site for the air conditioning and refrigeration industry. This is now part of everyday life, and most people are familiar with it and comfortable using it,” says John Pritchard.
The site is underpinned by a huge knowledge bank, containing details of most of the components used in the manufacture of York brand chillers since production began. The database contains some 200,000,000 individual records, taken from the Bills of Materials (BOMs) for York chillers.
These contain detailed engineering data and component lists for every machine made. Chillers are identified with a unique serial number, printed on the data plate inside the chillers’ controls cabinet. There are believed to be around 10,000 York chillers installed in the UK and many more further afield across Europe.
The site is designed to be dynamic and grow over time. As new chillers are manufactured and installed, the knowledge base is constantly updated.
“We began with information on chillers made in the original York Basildon plant, and then expanded to include machines made at other factories across the globe. That process is continuing as we build the knowledge bank,” says John Pritchard. “It is an ongoing project, and as the database expands it becomes evermore useful for customers.”
Johnson Controls provides training in the use of the system at its Basildon site, or on-line, and will also be demonstrating how it works to visitors at the forthcoming ACR Show 2016, taking place at the NEC from 16 to 18 February 2016.

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.

South Africa: CCTV footage has emerged of an air conditioning technician in a dramatic fall through a seven-metre high roof having survived with only minor injuries.
The incident occurred when Doors Kleyhnans’ who was working on the roof air conditioning units at an automotive service centre in Bloemfontein, South Africa stepped on a part of the roof, which unbeknown to him was made of fibreglass.
Kleynhans said, “When I stepped on the roof, I heard it crack, but before I could get off, it gave way.”
The footage show’s Kleynhans crash-landing into a Volvo that was in for repairs, causing extensive damage to the vehicles rear window and roof.
A second CCTV camera then catches Kleynhans jumping up after the fall and running out of the service centre in shock.
Staff in the centre ran after him, trying to calm him down and determine if he had broken anything.
Kleynhans said, “I told them that I was fine and they should not worry. They kept on telling me to lie down.”
Kleynhans was taken to a local hospital for X-rays, where no fractures were found.
One lucky guy!
CHINA: Chinese air conditioning manufacturer Haier, have announced the launch of their first R32 refrigerant systems.
The R32 air conditioning systems have been added to their popular energy saving Super Match range of split systems and are said to be fully compliant with building energy saving standards in Europe, North America and Australia.
In addition, the lowest operating noise of the product is claimed to be 26 db(A).
INDIA: A 26-year-old air conditioning engineer was killed on Saturday morning when two compressors on an air conditioning plant he was working on exploded.
According to reports the victim, Nasim Ansari and his colleague were servicing one of the central air conditioning plants at the R Odeon shopping mall in Ghatkopar following reports of a refrigerant leak.
Following the blast the police and the fire brigade were called where they discovered the severely burned body of Ansari, who was subsequently declared dead at the scene.
Assistant Divisional Fire Officer C R Pawar said there was a gas leak in the plant and Ansari had been called to fix it. "It appears the leak had not been plugged properly which triggered the blasts."
According to the Times of India, Senior police inspector SA Dhanavade said they have lodged a complaint of causing death by negligence against Ansari’s employer adding "The arrest will be done after getting details of the contractor whether he has given proper training to the victim to handle the plant servicing and why the victim was not provided with safety gears."
Ansari’s colleague was uninjured as he was said to have been fetching tools from the van at the time of the incident.
