UK:  Carrier Rental Systems (UK) Ltd, the UK’s leading temporary cooling and heating specialist, has supplied high-efficiency chillers and heaters for the downhill ice track at the Red Bull Crashed Ice event in Belfast, Northern Ireland

Carrier Rental Systems’ timely supply of high-performance cooling and heating equipment, coupled with its experience of supporting large-scale outdoor ice-based activities, ensured a successful event for Red Bull, the global energy drink manufacturer.

Described as one of the world’s fastest sports, the competitive ice cross downhill competition was one of four Red Bull Crashed Ice outings of the Ice Cross Downhill World Championship staged throughout the year, attracting global participation from competing teams. It was the first such Red Bull event staged in the UK.

With a combined cooling capacity of 1.6MW, Carrier supplied four AquaSnap air-cooled chillers to the Stormont site that circulated a 40:60 mixture of glycol and water at -10deg C through the AST “Skateway” system, incorporating a flexible carpet of tubes running the length of the 430m long track.

Once the chillers were connected, water was sprayed onto the freezing surface, taking 10 days to produce a 4.5 inch-thick layer of high quality ice.

In addition to chillers, Carrier Rental Systems also supplied a boiler-based heating solution. Two 400kW units provided hot water at 45deg C to melt the ice track after the culmination of the three-day competition.

UK:  When it comes to designing and maintaining energy efficient cooling and heating systems, Star Refrigeration is undoubtedly an innovator for delivering low carbon, cost saving solutions.  So as Europe begins its scheduled phase down of selected HFC refrigerant gases, Star is urging food manufacturers to take a long term, strategic view of their refrigeration systems - or face significant financial penalties.

Star believes that new European F-Gas Regulations will dramatically affect the cost and availability of synthetic refrigerants with high global warming potential, warning that refrigerant suppliers have indicated that the price of some widely used HFC gases may increase by up to 20% this year.

Over the past fifteen years, the refrigeration industry has seen the gradual phase out of synthetic, ozone-depleting refrigerants. From January 2015 the last of these HCFC gases, including R22, were banned in Europe.

Star Refrigeration Group Sales and Marketing Director Rob Lamb says: “As the phase down of HFC gases with high global warming potential takes place over the next 15 years, we predict that there will be a rapid increase in cost and a marked decline in their availability.”

He adds: “We would urge refrigeration plant operators to think strategically and take a long term view of their manufacturing processes by investing in future-proof refrigeration systems.”

Whilst refrigerant suppliers are busy developing new blended synthetic gases with lower global warming potential, Star believes there is a long-established, natural alternative.

Rob Lamb says: “Natural gases such as ammonia have been successfully used as refrigerants for over 100 years. Ammonia has no global warming effect and offers high efficiency, long term availability and low cost per Kg. The use of carbon dioxide as a refrigerant is also growing in popularity due to its relatively low global warming potential.”

He adds: “The initial capital cost of plant that operates on a natural refrigerant may be higher, but the lifecycle cost of running the system is key. Those who continue to operate cooling systems with HFCs are facing the risk of escalating running costs in the short to medium term. We believe that natural refrigerants such as ammonia and CO2 offer long term security.”

UK:  Ofgem have reported that they have received an increasing number of complex questions about the eligibility of Ground Source Heat Pumps and shared ground arrays for both the Domestic and Non-Domestic RHI schemes.

In a statement Ofgem say they are aware that a number of installers are working on innovative developments, particularly in the social housing sector. These developments typically include shared ground arrays – with shared ground or water loops – providing heat to more than one heat pump unit located in each individual flat or house. As administrators of both schemes, Ofgem has set out a response to these new industry initiatives.

The 2014 Domestic RHI Regulations define a Ground Source Heat Pump as a plant that generates heat by absorbing energy stored in the form of heat from the ground, including water in the ground, or surface water, or both, and uses that energy to heat a liquid. It follows that a ground array forms part of the plant for the purposes of the Domestic RHI scheme.

Under the current Domestic RHI Regulations, any application involving a plant that is a heat pump seeking accreditation for the Domestic RHI can only be considered eligible if it provides heating solely to a single eligible property, assuming all other conditions are satisfied. 

Therefore a plant incorporating shared ground loop arrays that provide heat to more than one single eligible property is not eligible for the Domestic RHI scheme. However, a plant featuring a shared ground loop array, providing heat to multiple domestic properties, can be considered for the Non-Domestic scheme, assuming all other eligibility requirements are met for that scheme.

UK:  Dearman, the clean cold and power company, was today joined by the Minister of State for Universities and Science, Jo Johnson, at the official opening of its ground-breaking Clean Cold and Power Technology Centre.

The new facility is home to Dearman’s extensive research and development activities, which are focused on the delivery of a range of zero-emission cold and power technologies. 

The company is working on diverse applications of its technology for use in transportation, the built environment and logistics. All of these applications utilise the Dearman engine, a novel piston engine that is powered by the expansion of liquid air to provide clean cooling and power.

The Minister and senior Dearman executives were joined by representatives of industry and academia, for a tour of the new facility which includes: state-of-the-art engine test facilities; engine build and component machining facilities: and space for Dearman’s growing number of engineers, designers and analysts. The facility in Croydon, Greater London, also features all of the cryogenic infrastructure needed to run a series of liquid air cold and power systems.

The Minister of State for Universities and Science, Jo Johnson, at the official opening of Dearman's ground-breaking Clean Cold and Power Technology CentreDiscussing the visit, Minister of State for Universities and Science, Jo Johnson, said: “From an invention designed and built in the lab to this impressive technology centre, Dearman is one of the great success stories that gives the UK its reputation for driving innovation. I want to continue to make the UK the best place in Europe to innovate and grow a business and this new facility is a strong sign of the progress we are making to achieve this goal.”

Commenting, Toby Peters, Chief Executive of Dearman said: “Today is a momentous occasion for Dearman. Not just because it marks the opening of this ground-breaking research facility, which will be at the heart of Dearman innovation for years to come. But because it highlights the progress we have made, as a team, in such a short period of time. 

“Just over three years ago Dearman and clean cold were nothing more than ideas. Today we are a company of more than 50 hugely talented people, we have our own bespoke facility, we have made huge strides in developing our technology and our first application will begin real-world deployment soon. With the rapidly increasing global demand for cold and cooling of all types, especially in the rapidly emerging and developing economies, our vision is to create and supply revolutionary clean cold and power systems that deliver strong environmental benefits and are equally commercially attractive. I am very proud to say that today, our vision of clean cold and power came one step closer to becoming a reality.”

The Dearman Clean Cold and Power Technology Centre is home to more than 40 people, the majority of whom are engineers and technicians. That number will grow in the years to come as Dearman plans to extend its activities, expand its range of applications and begin after-sales and support services. 

The first application of Dearman technology is a zero-emission transport refrigeration system, which will begin commercial field trials later this year, before extensive international trials begin in 2016. Subsequent Dearman applications will include a clean power and cooling system for buildings, an auxiliary power unit for buses and HGVs, and a liquid air heat hybrid system for trucks and buses. 

Dearman is also developing its world leading expertise, which will enable it to advise organisations on the application of integrated cold and power technologies, helping them to reduce emissions and save money.

UK:  A major R22 chiller replacement project at Salisbury Hospital has set what is believed to be a new industry record for underground refrigerant pipework on a Turbomiser installation.

Four new chillers, with a combined cooling capacity of some 1.4MW, are connected to air-cooled condensers by DX pipework up to 75m in length. The large-gauge copper tube (up to 3in 5/8 on the discharge and 2in 5/8 on liquid lines) runs beneath a road in a concrete-lined culvert.

The installation, which took nine weeks to complete, required refrigerant pipe to be mounted on custom-fabricated brackets every 1.5m along the length of the underground structure. Each chiller and condenser is on an independent circuit.

The air-cooled condensers sited on existing mountingsThe high efficiency R134a-based chillers replace four aging R22-based Hitachi units, on dual screw compressors, believed to be up to 20 years old. The Turbomisers were installed on the existing mounting points, however they occupy two-thirds the space, due to their high performance relative to their size.

The Turbomisers, fitted with an Economiser based on a high efficiency brazed plate heat exchanger, provide cooling for the hospital’s air handling units, serving wards, administration areas and waiting rooms. They are linked to a hospital-wide Building Management System (BMS), with control based on return water temperature. The BMS controls chiller sequencing and run-time to even-out operational hours and prolong working life.

Cool-Therm provided a complete turn-key installation, including design, supply, installation and commissioning. The company has also secured a five year service and maintenance contract for the chillers.

Large diam refrigerant pipes connect chillers and condenser either side of a roadIn a previous project at the site, Cool-Therm supplied a packaged air-cooled Turbomiser chiller, complete with integral condenser, enabling it to be located in a restricted space in an enclosed area of the hospital.

Rob Young, Cool-Therm project director, said: “Due to the need to maintain continuity of cooling throughout, it required a carefully managed staged approach. Because of the time of year, we were able to remove three of the four original chillers and leave one operational, after ensuring it was capable of meeting all anticipated demand.

“When two of the three new systems were operational, the fourth original unit was decommissioned and removed, and the final chiller and associated condenser installed.”

He added: “The need to route pipe work under a road and a delivery area obviously added an extra dimension, and one that we had not encountered before. However, the custom-designed mounting system we developed proved very effective.”

Jerry Henderson, who headed the project for Salisbury Hospital, said: “The new Turbomisers are part of a hospital-wide efficiency programme, designed to reduce running costs and improve our carbon footprint. We were impressed by the proven performance of the chiller and the significant potential energy savings. Cool-Therm were highly professional and worked closely with our on-site team to deliver a complex project ahead of schedule, and – crucially – without interruption to hospital cooling.”

The Cool-Therm installation team was led by Simon Umlandt, assisted by Steve Baker and Andy Comerford.

UK:  The new Refrigeration Air Conditioning and Heat Pump (RACHP) Engineering Technician Apprenticeship standard and assessment strategy has now been published on the list of approved standards on the Government Trailblazer website.

The Refrigeration Air Conditioning and Heat Pump (RACHP) Engineering Technician Apprenticeship Standard reflects the needs of employers who employ a range of apprentices to carry out work in a variety of roles in installation, commissioning, service and maintenance of systems in a variety of application use such as retail refrigeration in supermarkets, bespoke industrial freezing processes, and air conditioning or heat pumping in commercial buildings.

The standard and the assessment plan have been developed by employers in consultation with providers over the past 18 months, supported by the Institute of Refrigeration Education Committee.

IOR President, Graeme Maidment, commented "We are delighted that the IOR's leadership in education in the RACHP sector has been recognised as a trailblazer.  The new Apprenticeship has been developed on conjunction with employers and in consultation with providers. This has resulted in a framework that is forward-looking and will provide the educational foundation for the needs of our industry. We look forward to supporting all employers in the RACHP sector in implementing the new apprenticeship scheme from September 2016."

It is hoped that employers will be able to start Apprentices on the new scheme from September 2016.  Assessment Organisations (such City & Guilds) need to register for approval before they can begin developing materials for the new Apprenticeship (such as workbooks, on line exams, specifications for practical tests and setting up an independent end point assessment panels). It is a recommendation in the new Apprenticeship that input from professional institutes such as the IOR is gained in the development of these materials or qualifications, to ensure that current industry standards are met and that they satisfy Engineering Council Engineering Technician requirements.

Employers will be able to choose which Assessment Organisation and Training Organisation they want to use for the RACHP Apprenticeship, and allocate the matched Government funding accordingly. The government Apprenticeship website will list the options available to employers and explain how much funding is available in due course.

The new Standard and Assessment plans place a much stronger emphasis on core refrigeration principles and science, backed up with practical assessments.

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.
