Revision to EN 378 Now in Force

The Institute of Refrigeration Ireland (IRI) sits on the EN 378 Technical Committee and the Working Group, and both continue to meet two or three times per year to address outstanding queries and ongoing developments relating to the Standard. The next meeting is scheduled to take place in Aachen in November 2017.

Familiarity with EN 378:2016 is crucial for companies who design, construct, install, commission, operate, maintain or use vapour compression systems for refrigeration, air-conditioning, heat pumps and chillers.

The Standard is published in four parts and, thanks to IRI’s active participation in the Working Group and its engagement with the National Standards Authority of Ireland (NSAI), it has secured a very significant discounted price of €155 for IRI members for the full set of four parts. As far as IRI is aware, this is the lowest price for the Standard in any EU member state, even with the IRI membership fee included!

It is worth noting that Part 2 (and the introduction, terms and definitions of Part 1) of EN 378 are harmonised with the Pressure Equipment Directive and the Machinery Directive. In fact, one of the drivers for the revision was to better align EN 378 with the Pressure Equipment Directive which has itself also been revised.

Members wishing to purchase a copy of the four parts of the EN 378:2016 Standard should contact the NSAI directly. Simply send an email with your name and IRI membership number to info@ standards.ie and quote “special IRI members’ discount for IS EN 378 Parts 1 to 4: 2016”. Alternatively call NSAI at 01- 857 6730.

Building Services News Celebrates 50 years of Continuously Serving the Industry!

Joe and Pat

Joe and Pat

Right from the outset Building Services News has been an integral part of Ireland’s building services industry and not just a magazine serving the sector. Publisher and Editor Pat Lehane sits on the executive of most of the industry professional and trade representative bodies and the journal has been instrumental in the establishment of many of these organisations.

In addition, Building Services News plays a major role in promoting and facilitating cross-over activity between these bodies, and provides secretariat support and accommodation addresses for many. It also guides and champions many industry causes, coordinating joint activities into lobbying and petitioning groups to act on behalf of the industry as a whole.

Building Services News provides the industry with saturation coverage of the building services sector. It is available in three formats – the print edition which is posted directly to individually-named industry personnel; the web edition, which is freely available to all; and the Facebook page, which is inter-linked with the web edition.

To all of you participating with us in this celebratory golden anniversary edition we say thank you. A small number of you have been dealing with the publication since day one, while many others have been trading partners for a considerable number of years. Of course there are also those of you who have joined us in recent years. In marking the occasion our collective vision should, and is, on the future.

In perusing the archives spanning 50 years we now realise how lucky we are to be part of such a vibrant, dynamic industry sector. In the early days the role of building services was perhaps under-rated by society in general.

Today, that has changed. Rising energy costs, a demand for more comfortable home and working environments, and a genuine sense of social responsibility in respect of the environment has put building services centre stage. What an opportunity – the future for the industry is bright and secure!

However, commercial success is only part of the story. The building services sector is also very much about people, and about a work/social interactive balance. We have been lucky to have made many friends down through the years. Sadly, some of them are no longer with us.

We dedicate this issue to their memory.

Refrigeration Lifecycle Cost Analysis — Value-Selling the Way Forward Says Alex Williams

Alex Williams, Commercial and Specification Consultant, Danfoss.

Alex Williams, Commercial and Specification Consultant, Danfoss.

When making a decision to specify, replace or upgrade refrigeration equipment, it is important to remember that the system’s lifetime running costs are often several times greater than its initial purchase cost. To illustrate this, Danfoss has developed a number of lifecycle software tools that compare the energy usage of various refrigeration condensing units so as to uncover the true cost of ownership.

By combining anticipated usage rate, energy cost per kWh and a few key points of data known to the equipment manufacturer, it is possible to produce an analysis of costs within a product’s lifecycle.

Stark differences                                                                                                                                Lifecycle calculation frequently shows that over a given period, refrigeration equipment running costs can be several times greater than the initial equipment purchase price. Incredible though it may seem, running costs are very often overlooked in favour of a small, short-term cost saving offered by a cheaper unit that consumes energy at a much greater rate. Like-for-like comparisons often reveal stark differences in the energy consumption and actual running costs.

For example, take two refrigeration condensing units that are available to achieve a desired cabinet or coldroom temperature. Unit A is €200 cheaper to purchase and appears to be the best option. However, lifecycle calculation reveals that its energy consumption is 500W per hour greater than the more expensive Unit B. In real terms, this translates to an additional €300 on the annual electricity bill when using Unit A.

As such, the initial €200 saving offered by Unit A evaporates within the first year of use and it quickly becomes a much more expensive option. Spending a little more to begin with on Unit B could potentially save the end user as much as €1,300 in energy costs over five years.

A contractor providing this information offers greater support to the customer and enables the enduser to make a much more informed decision when planning to install new equipment or upgrade/replace aging equipment.

The installation of energy efficient equipment benefits us all but it does not have to come at a cost. Indeed, lifecycle calculation provides a great deal of evidence that by purchasing for the longer-term, large savings are more than possible. Pressure faced on the initial purchase price is reduced when energy consumption cost is given the proper consideration.

IRI Awards night freezes no one out!

Liam Kirwan, Daikin with Keith Mc Greevy, Tech Refrigeration & Air Conditioning, Seamus Kerr, IRI President, Eoin Lennon, Novum Overseas and Dave Killalea, Carel Ireland.

This year’s recent Irish Refrigeration Institute Awards night proved yet again that, of all the building services-related representative bodies, IRI is unique. It somehow manages to combine the serious matter of peer-vetted industry awards with a wonderfully-relaxed social occasion.

As always, a capacity attendance convened in the Crown Plaza Hotel, Santry in Dublin’s northside, for an evening of presentations, food, fun, entertainment and dancing into the early hours.

President Seamus Kerr and his committee deserve great credit for the format of the occasion, and especially for keeping speeches to a minimum. Indeed, there were no speeches as such, save perhaps for some of Seamus’ more obscure ramblings and observations!

It may be the refrigeration sector flagship event, but the atmosphere is warm and inviting. Well done to all involved in making it such a successful and enjoyable evening. Award winners were as follows:

IRI Environmental Award — Daikin Ireland/Carel Ireland/Tesco Ireland

IRI Energy Award— Cross Refrigeration Ltd

IRI Contribution to Industry Award — Dermot Byrne

IRI Training Award — Tech Refrigeration & Air Conditioning

IRI Young Engineer Award — Keith Mc Greevy, Tech Refrigeration

IRI Innovation Award — Novum Overseas

Clean rooms and comms are easy – not so a mobile ice cream parlour mounted on a tractor chassis!

Over the years John Kelly and the team at Kelly Refrigeration & Air Conditioning, based in Tramore, Co Waterford, have carried out some unusual and challenging projects that called for fresh thinking and innovative solutions. However, when asked to convert a standard single-head ice cream machine to operate off the engine of a vintage tractor you could forgive them for thinking it was a practical joke. But it was not.

The story began when locally-based John Kent of John Kent Engineering approached John Kelly to design and build a fully-functional mobile ice cream “parlour” – mounted on the chassis of the tractor – so it could be safely used to provide ice cream across the wide expanse of the beach in Tramore.

As the photo clearly illustrates, John Kent Engineering did a fantastic job on the bodywork … the question was, could Kelly Refrigeration & Air Conditioning provide the means to deliver the ice cream?

A critical factor was to pre-cool the ice cream mix carried on board the tractor, without it rising in temperate during the day. After a great deal of deliberation, a single-head Coldelite ice cream machine was selected, and the standard compressor removed from within and then mounted on the back of the tractor.

The next stage was to size the correct pulleys to match to the drive shaft so it would supply the correct RPM’s at the pump and beater while the tractor’s engine was in idle mode. A clutch-driven pulley was fitted to the compressor which was then mounted onto the tractor’s engine to provide the correct speed to produce the required cooling. To maintain head pressure a high-powered 12-volt condenser fan motor was fitted to the condenser. The entire system operates on 404A refrigerant.

A small insulated cabinet was then installed to hold the day’s supply of ice cream mix with the required cooling provided by a remote condensing unit mounted over the cab of the tractor.

A cooling coil within the cabinet provides a build up of ice within the cabinet and this maintains the required temperature throughout the day. Finally, a heat exchanger was fitted to the tractor engine and its own water tank to provide hot water for the day-to-day operations.

Hey presto … simple really with a bit of knowledge, experience and imagination.

Make mine a 99 please!

F Gas 'Compromise Agreement' Means Product & Market Development Can Now Proceed

Mike Nankivell

ACRIB, on behalf of UK trade associations and professional institutes, has welcomed the news that the European Commission and Parliament reached a compromise agreement on the revision of the F Gas Regulation at the end of 2013. Although the precise details of the phase downs, bans and other changes have not yet been released publicly and are still subject to ratification, the importance of the agreement is that it will allow legislators to move forward and provide certainty for the industry.

With many end-users already facing difficult decisions about replacing R22 equipment and trying to decide on the best long-term solution for new equipment, a clear position from the EU on future availability of HFC refrigerants has got to be a good thing. Had no decision been reached we could have faced a further two years of uncertainty in which many important investment plans could have been put on hold, the stimulation of the heat pump market seriously compromised, and end-users attempting to extend the use of old R22 plant beyond the reasonable life of the system.

A controlled phase down of HFCs and limited bans on specific applications – where cost-effective, proven and energy efficient alternatives are known to be available – is a sensible approach. It will allow the industry to continue to use the most appropriate refrigerant for the application in terms of efficiency, safety, cost and availability in both existing situations and when selecting new equipment.

The timescales will allow for improving our knowledge and skills in the use of alternative refrigerants, particularly those still under development. Other aspects of the regulation such as creating a recycled market for HFCs up until 2030 and encouraging greater legal responsibility of suppliers are also welcomed.

Summary of outcomes of the compromise                                                                                                 – New requirements on containment, use, recovery and destruction of HFCs, as well as possible changes to future training and certification;

– A gradual HFC cap and phase-down from a base of 2009 – 2012 down to 21% by 2030.

– Bans on the use of certain HFCs with higher GWPs in some new equipment such as domestic refrigerators (by 2015), commercial refrigeration (by 2020/2022), and low-charge split system air conditioning (by 2025);

– Restrictions on placing on the market certain products containing or designed to contain F gases;

– Some restrictions on servicing and maintenance of equipment using HFCs;

– Proposed date of entry into force of 1 January 2015.

I am satisfied that the outcome of the Trilogue process is the best the industry could have hoped for given that there were some difficult compromises to be made. Although still subject to a legal check on the text and final endorsement through a vote in the European Parliament’s ENVI Committee and Plenary Session in the first quarter of 2014, the agreement will provide the regulatory certainty in the refrigeration, air conditioning and heat pump markets, which is so absolutely vital.

It also represents a consensus on a series of proposals that will not only meet the EC’s GHG emission reduction targets, but also justifies the consistent message that the ACRIB F Gas Group has maintained throughout its close involvement in the review process.

ACRIB met as a Board on 15 January to discuss the next steps and will be seeking further meetings with relevant UK Government Departments to share industry responses and determine the best approach towards disseminating the new requirements.

Meanwhile, we in the F Gas Implementation Group will continue to work with all interested parties to ensure awareness and offer technical advice on the impact of changes to the Regulation, once confirmed. We will also ask the Department for Environment, Food & Rural Affairs (DEFRA) to hold an industry stakeholder meeting to explain the process of their implementation as the details of new requirements are finalised over the next few months.
