UKRAINE CALLS FOR SUPPORT FROM COOLING INDUSTRY

UKRAINE: The Refrigeration Association of Ukraine has called on European refrigeration and air conditioning companies to cease the supply of equipment to Russia and Belarus.

With the worldwide sanctions growing in condemnation of Russia’s invasion of Ukraine, Serhii Anashkin, chairman of the Ukraine Refrigeration Association has written to European association AREA thanking those who have sent Ukraine letters of support and offers of help.

He now calls on the air conditioning and refrigeration industry “to completely interrupt supply chains to the Russian Federation and the Republic of Belarus” and pleads for companies not to invest in projects related to Russia and Belarus.

Anashkin points out that refrigeration technologies “are used in missiles to cool rocket fuel, missile warheads (charges), on ships and military equipment to cool their engines and crews, combat crews, at military warehouses and weapons plants”.

In addition, in these exceptional circumstances, Anashkin asks if European companies can offer Ukraine deferral of payments for equipment and components as it struggles to keep shops, hospitals and blood banks operating.

TECHNICAL BULLETIN

AMMONIA REFRIGERATION This technical bulletin is aimed at persons conducting a business or undertaking (PCBU’s) who design, install, commission, own, operate or maintain ammonia refrigeration plant.

PURPOSE It is designed to help PCBUs understand their responsibilities under the Health and Safety at Work Act 2015 (‘HSWA’), the Health and Safety at Work (Hazardous Substances) Regulations 2017 (‘the Regulations’) and the Health and Safety in Employment (Pressure Equipment, Cranes, and Passenger Ropeways) Regulations 1999 (‘PECPR’). It also provides advice on what PCBUs using ammonia can do to fulfil their duties.

BACKGROUND The uncontrolled release of ammonia from refrigeration plant is a critical work health and safety risk. It has the potential to cause death, a severe permanent disability or life shortening illnesses. Critical risks must be managed effectively to minimise the risk of harm to workers, emergency services and the public.

In the last year, approximately 20 ammonia releases were notified to Work Safe New Zealand. Some workers were taken to hospital, some treated at the scene, and others were at risk but unharmed.

At a recent incident, a pressure safety valve opened (and failed to close) causing three workers to be seriously harmed. The workers required decontamination and medical treatment.

These incidents highlight the importance of risk assessments and implementing appropriate control measures including training, and having a written preventive maintenance plan and a compliant emergency response plan.

WHAT IS ANHYDROUS AMMONIA? Anhydrous ammonia is a toxic and corrosive substance that is supplied in cylinders as a liquefied gas. The gas is pungent, and very irritating to the eyes, nose, and respiratory system. It is flammable in high concentrations.

On release to the atmosphere, one litre of liquid expands to 850 litres of gas, which therefore makes the release of the anhydrous ammonia liquid a much greater risk than a release of the gas. Low level exposure through inhalation can cause coughing and breathing difficulties, where high level exposure through inhalation can cause lung damage, leading to death. Contact of liquid with the body must be prevented.

Symptoms to looks for when exposure to ammonia is a risk: – difficulty breathing – irritation of the eyes, nose or throat, and – burns or blisters.

7

WHAT ARE THE CAUSES OF AMMONIA RELEASE? The two main causes of ammonia releases are:

EQUIPMENT FAILURE

HUMAN FACTORS

– Corroded pipework

– Failing to establish and follow a written preventive

– Leaks from rotating shafts (and valve glands) – Failure of high level and pressure cut out switches, and safety valves.

maintenance programme – Missing procedures: Failing to establish or follow safety processes or procedures – Not identifying hazards correctly – Missing critical control measures (such as those identified in recognised New Zealand Standards) – Ineffectively managing change and safety critical control measures – Not having an effective emergency response plan – The PCBU and refrigeration contractor not consulting with each other to manage their overlapping duties.

PRIMARY DUTY OF CARE Under the Health and Safety at Work Act PCBUs with ammonia-based refrigeration systems at their workplaces have a duty to ensure, so far as is reasonably practicable, that the health and safety of their workers, and others (e.g. members of the public) is not put at risk from the release of ammonia. Risks must be eliminated so far as is reasonably practicable. If a risk from an uncontrolled release of ammonia can’t be eliminated, it must be minimised so far as is reasonably practicable. Some of the steps workplaces can take to manage the risks from ammonia release are: – regular maintenance of plant, with emphasis on safety-critical devices – ensure all warning and ventilation systems are fully operational – review of control measures to ensure they are in line with industry standards – provide workers with personal protective equipment (PPE) such as respiratory, eye and skin protection to minimise exposure.

– high-risk tasks (such as adding or removing ammonia or compressor oil) should have a written operating procedure.

Good communication between the service provider PCBU (that services or maintains the plant) and the owner/operator PCBU (with management or control of the workplace and/or plant) can help manage the risk of an uncontrolled ammonia release.

Should any escape, leakage or spillage of ammonia occur, PCBUs are required to notify WorkSafe as such leaks are notifiable events.

irhace.org.nz

MAY 2022

HAZARDOUS SUBSTANCE CONTROLS There are a number of controls that workplaces must follow under the Health and Safety at Work (Hazardous Substances) Regulations. PCBUs must: – Establish and maintain an inventory, which includes a safety data sheet (SDS), or a condensed version of the SDS, for each substance.

– Ensure the ammonia is secured from access by unauthorised persons.

– For 100 kg or more of ammonia contained within the plant, the PCBU with management or control of the workplace must have an emergency response plan (ERP). The plan must: -- address all reasonably foreseeable emergencies that could happen if controls fail or are breached -- state any special training needed to deal with an emergency involving ammonia -- include the inventory and a site plan showing where the ammonia is located in the workplace.

– In addition, the PCBU has duties to ensure the plan, and the equipment, facilities, and people described in it, are available, including to emergency service providers. The PCBU must also ensure that the emergency response plan is tested every 12 months to demonstrate whether it is workable and effective, and is implemented in the event of an emergency.

PECPR CONTROLS The Health and Safety in Employment (Pressure Equipment, Cranes and Passenger Ropeways) Regulations also contain controls that apply.

These regulations establish controls on pressure equipment, including inspection and certification by third party equipment inspectors. Requirements include the need to ensure equipment is safe, is operated safely, is operated within design limits, and is maintained in safe condition. All such equipment requires a current certificate of inspection.

EFFECT OF OTHER LEGISLATION We accept that most facilities that utilise ammonia in refrigeration systems are beneath the thresholds for designation under the Health and Safety at Work (Major Hazard Facilities (MHF) Regulations. However, the information, process requirements and processes used by MHF’s contain good guidance that could be utilised in many installations that have such systems.

DANFOSS TO BUILD ENERGY-EFFICIENT “SMART” SUPERMARKET DENMARK: Danfoss has begun construction of a fully functioning 1,500m2 supermarket to incorporate the latest and most energy-efficient refrigeration and heating technologies.

The Smart Store supermarket will be situated right next to Danfoss’ headquarters in Nordborg and is designed to be an example of how supermarket chains around the world can build climate-friendly and sustainable stores with the technologies that already exist today.

Danfoss has previously promoted the “smart store” concept of next generation food retail solutions at exhibitions like Euroshop, now the Danish manufacturer is bringing that vision to reality.

Scheduled for completion in the summer of 2023, the store will employ CO2 refrigeration, with the system’s waste heat being recovered and reused to provide heating for the supermarket and the local community through district energy.

Brugsen for Als and Sundeved, Denmark’s largest independent supermarket association, will rent the building from Danfoss and will install a COOP 365 discount supermarket.

Additionally, the site will serve as an Application Development Centre where Danfoss will work together with partners to co-develop new technologies and explore interfaces in the energy system surrounding energy storage.

Lars G Andersen, MD of Brugsen for Als and Sundeved (left) breaks ground with Danfoss’ Kristian Strand

“The origins of this project go back a long time, but the new energy-efficient Smart Store supermarket that we are starting to build today has only grown in relevance. The goal of the project is to show how easy and profitable it is to decarbonize our economy and ensure reliable and sustainable energy use,” explained Kristian Strand, president, refrigeration & A/C controls, Danfoss Climate Solutions. “The solutions we are building here today represent the core of Danfoss solutions and will showcase how we can approach zero energy use in food retail together.”

“The supermarket will be the focal point for a new part of our campus, where all buildings will be energy-efficient and meet special sustainability requirements. Our aim is to boost the green transition with concrete evidence of how far we can go with energy efficiency,” added Danfoss Climate Solutions president Jürgen Fischer. “We want to demonstrate to customers and partners how energy saving solutions work in real life.”

The service part of the building will be handled by Ohmia Retail, a Norwegian partner responsible for the operation and monitoring of all installations. The supermarket will be able to supply surplus heat to the local Nordals Fjernvarmeværk district heating plant.

The 1,500m2 COOP 365 store will occupy a 14,000m2 site that will include an OK gas station and a car wash. Danfoss will own all installations in the store, allowing continuous monitoring and optimisation of systems. It will enable Danfoss to continuously test applications, new products and include a showroom and training facility for visitors and customers.

“Our new Smart Store shows what is possible with today’s technology, such as our Alsense software. The integration of hardware and software tools into this store underscores the growing importance digitalisation has for the green transition,” said Tuuli Sarvilinna, Danfoss’ senior vice president electronic controllers and services.

Brugsen for Als and Sundeved works together with COOP, and already has a total of 13 stores in the area around Sønderborg in Denmark. Since 2015 it has consistently reduced the consumption of energy, achieving a 44% reduction in total CO2 emissions.

“Our 13 supermarkets have been modernised and we have nearly no cost for heating in the stores because the heat comes from our freon-free refrigeration systems, solar cells, and heat pumps,” said the group’s MD Lars G Andersen.

THE IIR PUBLISHES TWO NEW IIR INFORMATORY NOTES ON

ENERGY RECOVERY! The thermal loads of buildings, apart from internal gains, can be classified into two main categories: losses or gains through the envelope and ventilation loads.

Ventilation loads are becoming more important as air purity standards and thus fresh air supply rates are increasing. Heat recovery from the exhaust air can strongly reduce these loads by pre-heating or pre-cooling the fresh inlet air. Heat recovery in a ventilation system allows significant energy savings, particularly when outdoor conditions differ greatly from the indoor ones. Moreover, when a recovery system is provided, the installed capacity for heating and cooling can be strongly reduced.

The IIR Informatory Note on Energy Recovery in Mechanical Ventilation Systems analyses the possible energy, environmental and economic benefits of this technology according the climate in which the building is located.

It concludes that heat recovery in mechanical ventilation systems may reduce the usage of fossil fuel with payback periods of one or two years.

The IIR Informatory Note on Air-to-Air Energy Recovery Equipment describes the performance, characteristics and operating modes of the great variety of appliances available for use in building ventilation heat recovery or in process-to-process industrial heat recovery. The energy benefits of heat recovery can allow energy cost reductions that can easily exceed 70%.

Summaries for policymakers outline the main conclusions and recommendations of these new Informatory Notes and are free to access.

ASHRAE POSITION DOCUMENT ON

INFECTIOUS AEROSOLS

The pathogens that cause infectious diseases are spread from a primary host to secondary hosts via several different routes. Some diseases are known to spread by infectious aerosols; for other diseases, the route of transmission is uncertain. The risk of pathogen spread, and therefore the number of people exposed, can be affected both positively and negatively by the airflow patterns in a space and by heating, ventilating, and air-conditioning (HVAC) and local exhaust ventilation (LEV) systems. ASHRAE is the global leader and foremost source of technical and educational information on the design, installation, operation, and maintenance of these systems. Although the principles discussed in this position document apply primarily to buildings, they may also be applicable to other occupancies, such as planes, trains, and automobiles.

ASHRAE will continue to support research that advances the knowledge base of indoor airmanagement strategies aimed to reduce occupant exposure to infectious aerosols. Chief among these ventilation-related strategies are dilution, airflow patterns, pressurization, temperature and humidity distribution and control, filtration, and other strategies such as ultraviolet germicidal irradiation (UVGI). While the exact level of ventilation effectiveness varies with local conditions and the pathogens involved, ASHRAE believes that these techniques, when properly applied, can reduce the risk of transmission of infectious diseases through aerosols.

To better specify the levels of certainty behind ASHRAE’s policy positions stated herein, we have chosen to adopt the Agency for Healthcare Research and Quality (AHRQ) rubric for expressing the scientific certainty behind our recommendations (Burns et al. 2011). These levels of certainty, as adapted for this position document, are as follows:

Evidence Level

Description

A

Strongly recommend; good evidence

B

Recommend; at least fair evidence

C

No recommendation for or against; balance of benefits and harms too close to justify a recommendation

D

Recommend against; fair evidence is ineffective or the harm outweighs the benefit

E

Evidence is insufficient to recommend for or against routinely; evidence is lacking or of poor quality; benefits and harms cannot be determined

ASHRAE’s position is that facilities of all types should follow, as a minimum, the latest published standards and guidelines and good engineering practice. ANSI/ASHRAE Standards 62.1 and 62.2 (ASHRAE 2019a, 2019b) include requirements for outdoor air ventilation in most residential and nonresidential spaces, and ANSI/ASHRAE/ASHE Standard 170 (ASHRAE 2017a) covers both outdoor and total air ventilation in healthcare facilities. Based on risk assessments or owner project requirements, designers of new and existing facilities could go beyond the minimum requirements of these standards, using techniques covered in various ASHRAE publications, including the ASHRAE Handbook volumes, Research Project final reports, papers and articles, and design guides, to be even better prepared to control the dissemination of infectious aerosols.

RLNZ STRATEGIC REVIEW RLTB Board trading as RLNZ has been strategically reviewing the way that it has been operating and as part of this are reviewing its delivery of training and technical education. As a charitable trust, our main purpose is to promote, educate, and train people in the refrigeration, heating and air conditioning industries, as well as engage with our third-party training providers and other key stakeholders, maintain vocational training standards through a robust quality assurance process, deliver on strategic industry driven training initiatives and encourage our people to further their professional development through a range of technical and specialist courses.

Recently a meeting was held between interested parties representing our industry, representatives from Worksafe, Competenz, IRHACE, CCCANZ, RLNZ, RPGNZ and current and previous members of the SAG committees were present. RLNZ was recognized by all as the training body to liaison with Worksafe for the HVAC+R industries.

The RLNZ board is made up of four councilors, Matt Birch Chair 2022, Brendon Clarkson Deputy Chair 2022 and councilors Dave Nicolls and Paddy Durham.

We have been working on several areas: • In the technical education area, RLNZ have been working closely with their corporate trustees and IRHACE has released their CPD programme. This is a first for our industry and both IRHACE, CCCA and RLNZ are in full support of enhancing this programme.

• As part of this, IRHACE are also releasing their webinar series which is now giving both RLNZ and CCCA the opportunity to further enhance technical education via this platform.

• The Approved Fillers Course covering A1 refrigerants is completed and is being released early May with a A2/ A2L course being released early June.

• Both courses are theory only and include practical guidance material to assist your company to receive practical, hands-on training from your own qualified trainers, independent marketplace trainers or from trainers listed on the RLNZ website.

• RLNZ’s fillers courses have been peered reviewed by a group of independent HVAC+R industry specialist and have been given the title of competent industry approved training.

• Our aim is to also help your company source quality training courses (from other suppliers) which are RLNZ and Industry recognized as competent industry approved training.

Part of this strategic review has identified a couple of areas where RLNZ are short on depth including HVAC&R subject matter experts with practical on-job vocational training experience as well as industry professionals who are still currently actively involved within the industry and have proven technical skills.

• RLNZ are looking to establishing an independent team of subject specialist who will be able to peer review training material and courses offered by other training providers.

• We RLNZ will also offer other training providers an independent peer, industry review service of their training materials. Once this material meets recognised industry standards RLNZ will promote these courses on the RLNZ website.

WOMEN IN COOLING INTERNATIONAL NETWORK

The cooling sector delivers a tremendous number of benefits ranging from public health to food security to productive and comfortable workplaces and homes. It is a truly vital, dynamic, and rapidly growing field that represents a significant source of high-quality employment worldwide. However, this sector has the potential to contribute even more by increasing the number of women in its ranks at all levels and types of jobs, which include diverse professions ranging from CEOs to professors, from engineers to servicing technicians, just to name a few.

To help accelerate this process, a new initiative called the International Network for Women in Cooling (INWIC) has been launched to advance the engagement of women, promote career opportunities, and increase their overall participation in the sector, which includes refrigeration, air-conditioning, and heat pumps (RACHP). INWIC is led by the World Refrigeration Day (WRD) Secretariat and the United Nations Environment Programme (UNEP) OzonAction in cooperation with a highly-reputed group of founding partners, all of whom are active in this area – AIRAH (Australia), AREA (Europe), ASHRAE (Global), CAR (China), FAIAR (Latin America), IIR (Global), IOR (UK), ISHRAE (India), JSRAE (Japan), U-3ARC (Africa), and Women in HVAC&R (North America).

Although women make up half of the world’s population, they are significantly and visibly under-represented in the RACHP sector in all roles. INWIC seeks to reverse that trend. It is doing so while recognising that there are many excellent initiatives and structures established by different partners that are promoting women’s engagement in the RACHP field. However, more cooperation and information exchange at the global level is needed to link these individual efforts and make them even more meaningful and impactful, especially in developing countries.

There are over 300 national, regional, and international associations, organisations, and institutions in the RACHP sector, however initial research indicates that fewer than 20 (5%) of these have sections specifically for women. Corresponding data indicates that where these women’s sections do exist, there is a greater number of women who are actively involved in the committees and structures of these bodies, which in turn increases the opportunities to raise the visibility of women in the sector. “’You can’t be what you can’t see!’ There are not enough visible ‘women in cooling’ role models. We want to change that,” said Stephen Gill – Head of WRD Secretariat. “We will create a resource for girls and young women to see bitesize videos and read real-life stories from a diverse range of women in different roles within the cooling sector. This will also serve to connect and inspire women currently working in the cooling sector.”

In the next few months, INWIC founding partners will introduce several programs that directly support individual women and young girls to further engage and find opportunities that can support the advancement of their careers, the attraction to cooling education disciplines, and active engagement with the cooling community.

INCORPORATED SOCIETIES ACT UPDATED FOR FIRST TIME SINCE 1908 The Incorporated Societies Act 2022 was signed into law on 5 April 2022 but societies won’t need to do anything immediately. There is a transition period of several years to allow societies time to become familiar with, and prepare for, the new regime.

Both IRHACE and CCCANZ are incorporated societies and we will be following a governance process to be prepared for these changes.

HON DR DAVID CLARK

Commerce and Consumer Affairs

• Listing the matters that must be included in a society’s constitution (including internal dispute resolution procedures) • Clearly setting out officers’ duties (derived from case law) • Prescribing External Reporting Board (XRB) accounting standards for larger societies’ financial reporting • Sets out other dispute resolution and judicial review mechanisms available to members of societies and creates sector-specific offences The rules which govern New Zealand’s incorporated societies will be refreshed for the first time in 114 years.

The Incorporated Societies Bill passed its third reading in Parliament today, which modernises the way societies deal with internal disputes, clarifies officers’ duties and prescribes accounting standards for larger entities.

“New Zealand’s incorporated societies play a vital and often long-standing role in our communities - speaking up for workers, teaching our children sports, and raising money for good causes. It’s important that the law governing them reflects best-practice,” Commerce and Consumer Affairs Minister, David Clark said.

This is the first time the Incorporated Societies Act has had its legal, governance and accountability settings updated since 1908.

“The Bill keeps the best of the 1908 Act, while also collating useful case law in one place and filling in gaps where the rules are unclear.

“Today marks the conclusion of 12 years hard work by officials and successive governments to modernise this Act. I also want to acknowledge the input of the sector and the members of the public during the various stages of consultation,” David Clark said.

The Bill provides for a period of up to 18 months for the necessary regulations to be prepared and consulted on, before the new regime will enter into force. More information will be available on the Incorporated Societies Register website in due course.

TEMPERZONE’S ECONEX OPA

ENABLES MCDONALDS TO REDUCE THEIR ENERGY COSTS AND CARBON FOOTPRINT. McDonald’s Ti Rakau Drive and Manurewa restaurants were some of the first to take advantage of the energy savings and lower Global Warming Potential (GWP) that Temperzone’s Econex OPA has to offer.

Each restaurant required the replacement of existing HVAC equipment which consisted of two 50kW DX Air Handling systems using refrigerant R407C, these systems had been operating from between 16 to 20 years.

Kevin, the system designer from HVAC Design and Build, wanted to standardise the installation with Temperzone units with a view to future proof the HVAC solution.

After the specifications were shared with Temperzone, a discussion followed about a new product which was in the final stages of design and well suited to the requirements of this project, the 55.6kW Econex OPA 560 R32 Inverter rooftop packaged unit.

Econex OPA was the perfect solution for future proofing these restaurants. As entirely variable capacity systems with inverter compressors, EC plug and condenser fans, and dual electronic expansion valves, OPA Econex would enable a significant reduction in energy consumption when operating at part load outside of the peak seasons.

Assisting McDonalds in their ongoing efforts to reduce their carbon footprint, Econex OPA units utilise R32 refrigerant which would result in a significant reduction in refrigerant related GWP from 1774 (R407C) to 675 (R32). Also, with increasing costs due to levies and the ongoing phase out of higher GWP refrigerants, utilising lower GWP refrigerants is an increasingly important factor in achieving lower total lifetime cost of ownership of HVAC equipment.

Initially considered for this project were two OPA 550 R410a units on each site. The opportunity to utilise two OPA 560 R32 models enabled a total reduction in refrigerant related GWP, across both sites, from 160 CO2 equivalent tonnes down to 46 CO2 equivalent tonnes.

The design was finalised using Econex OPA units across both restaurants and installed in 2021.
