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.

UK:  Carrier has delivered substantial savings in carbon emissions and building operating costs for Citi, following a chiller upgrade project at the group’s London headquarters.

To meet the customer’s requirements for increased energy efficiency, Carrier upgraded two Carrier AquaEdge™ 19XR5 centrifugal chillers with variable speed drives based on Greenspeed® intelligence, enabling a significant reduction in operating costs.

Carrier designed and built a custom solution matched to the exact requirements of the project. This solution helps reduce chiller energy consumption by adjusting cooling capacity to match the building’s load in real time.

Carrier AquaEdge centrifugal chiller in situ in plant room

Based on an initial analysis carried out by the Carrier engineering team, the energy saving potential for both chillers upgraded with Greenspeed® intelligence was estimated at £126,000 per year. Power use was then monitored before and after the installation. During the first three months of operation, the results showed actual savings of £33,966, exceeding anticipated savings.

With Carrier’s variable speed drive system, end users can reduce energy use and cut their carbon emissions, as well as extend the working life of chillers. An added benefit is lower servicing costs, as the soft start and soft stop routines contribute to less wear and tear on the system.

A further benefit is a substantial reduction in noise, due to the modulation of compressor running speed. The Carrier system also helps deliver highly stable comfort conditions, as chiller output is closely matched to load, producing a more comfortable and productive environment for building occupants.

Carrier AquaEdge centrifugal chiller retrofit

The project was carried out in two stages. The first involved installing Greenspeed® intelligence on the first centrifugal chiller. The reduction in energy consumption as a result of the upgrade enabled Carrier to make a supported case for upgrading the second centrifugal chiller, which was accepted by the client.

During the installation phase, due to height limitations in the building’s basement plant room, Carrier co-ordinated the dismantling of the large variable speed drives before they were moved in three sections, and their re-assembly once in position in the plant room.

“The key aim of the project was to reduce energy use without affecting comfort conditions inside the building, in order to lower building operational costs and associated carbon emissions,” said Paul Clements, UK engineering asset manager, Citigroup Realty Services. “We worked closely with Carrier throughout the project to ensure the requirements were met. As the figures for chiller energy consumption demonstrate, the project has proved to be highly successful and met its objectives.”

As a result of the project’s success, Carrier has secured subsequent orders for several Greenspeed® intelligence upgrade projects on centrifugal chillers serving multi-storey commercial buildings in London and elsewhere in the UK.

EUROPE:  The European association of refrigeration, air conditioning and heat pump contractors (AREA) has today published a paper on the European strategy on heating and cooling which is due to be published by the end of the year. Stating that heating and cooling should be addressed in its own right and in a comprehensive way rather than scattered as part of other policies.

In the paper AREA re-affirms its general commitment to the objectives of the EU energy and resource efficiency policy. They do however say that as refrigeration and air conditioning technologies are responsible for a significant share of the global energy consumption, other aspects should be duly considered in the upcoming strategy, notably the role of refrigerant and the necessity to maintain contractors’ skills and knowledge.

The following are key points taken from AREA’s paper. The full text can be viewed here.

RACHP Contractors are technology providers at every scale

AREA say the Commission’s working document (issue paper III on technologies) rightly points out the key role of installers, who are the “intermediaries bringing together the technology and the user”.

However, AREA strongly opposes further descriptions of installers in this Commission’s working document. Installers are indirectly referred to as “bottlenecks” due to an alleged lack of training and supposed dislike of ‘non-conventional products’.  Such an assumption is generic, simplistic and unsubstantiated. 

Contractors are neutral toward technologies

RACHP contractors use every available solution with complete technology neutrality and with the sole aim of ensuring the highest level of reliability, energy efficiency and cost-effectiveness. They provide tailor-made solutions based on users’ specific needs. They work at all scales, from household air conditioning equipment to industrial refrigeration installations.

AREA strongly believes there is a place for all types of cooling technologies, simply because there is no ‘miracle technology’ that provides a one-size-fits-all solution. In this regard, the Commission’s working documents seem to put too much emphasis on district heating and cooling, which raises our concerns since it is not always the most suitable option. Instead, the upcoming heating and cooling strategy should be neutral towards technologies, promoting both large-scale and small-scale solutions depending on the situation.

Contractors have a key role to play

AREA acknowledges that the Ecodesign and Energy labelling Directives will improve efficiency of ventilation, air-conditioning and refrigerating equipment as well as heat pumps, which we support. However, without proper design of the cooling system, energy savings of efficient equipment can be totally negated.

  • Proper system design for new installations maximises the overall energy efficiency level of all the installation’s components, including the choice of refrigerant;
  • Professional installation guarantees the efficiency and reliability of the system;
  • Regular maintenance and servicing enables early leak detection and minimises emissions.

Therefore proper system design, effective installation, as well as regular maintenance and servicing are of the utmost importance to ensure that expected energy savings turn into reality.

The role of refrigerant should also be considered

The Commission’s working documents tend to focus on technologies only, without considering other aspects, such as refrigerants. In the cooling sector, however, refrigerants directly impact on the energy efficiency of RACHP systems.

This is why energy efficiency remains a key issue in refrigerant policy at EU regulatory level, especially the Regulation on fluorinated greenhouse gases (517/2014/EU). The so-called F-gas Regulation ensures that installation, maintenance, service, leakage checking, commissioning and disassembly of RACHP systems are undertaken by fully competent professionals.

This results in better containment of refrigerants and greater energy efficiency of the systems.

Maintaining contractors’ skills and knowledge is vital

The Commission working document mentions an alleged lack of awareness and knowledge of new technologies, and too few trained installers bringing these solutions to customers. AREA would like to provide some information on the state of training and competence of RACHP installers in order to avoid unwanted generalisations.

Refrigeration and air conditioning is a very innovative and constantly evolving industry. The high level of technicality of RACHP systems makes it necessary to have a corresponding level of competence from installers. Since 2006, this is ensured through compulsory minimum training & certification requirements embedded in the F-gas Regulation. These are largely based on the work undertaken by our industry in the context of the REAL Alternatives project.

AREA is fully supportive of harmonised initiatives fulfilling the same objective, as long as they are proportionate and coordinated. An EU Heating and Cooling Strategy should ensure such a coordination, taking existing schemes into consideration and avoiding duplicate or divergent requirements.

UK:  Mitsubishi Electric has announced that its entire range of Ecodan air source heat pumps has achieved A++ rating under the first Energy Related Products (ErP) Directive ruling for heating products across Europe.

From the 26th September, ErP will apply to domestic and commercial heating and hot water products, including electrical powered heating, gas and oil boilers, water heaters and cylinders, as well as renewable technologies such as solar thermal and heat pumps.

This means that all space and water heaters will need to display an energy label which will help both residential and commercial customers identify the most energy-efficient products on the market and brings heating products into line with other energy consuming goods such as fridges and washing machines.

To highlight the requirements under ErP Mitsubishi Electric has also released a short video which explains how the Directive is designed to help phase out lower performing products whilst having a positive impact on the emissions levels across Europe and increase the share of renewable energies by 20 per cent.

ErP is a significant piece of legislation that will have a major impact on the sale and use of heating systems in the UK.  As such, the requirements of ErP is already being embedded into legislation on the energy efficiency of buildings and as incentive schemes for renewable technologies.

In order to apply for Renewable Heat Incentive (RHI) payments, heating systems will now needs to comply with the Microgeneration Certification Scheme (MCS), which sets industry standards for products used to produce heat from renewable sources.
