Productivity on the go at Heatcraft
Heatcraft continues to develop its smart@ccess platform with customers now able to check stock
availability and order from the new online product catalogue.
“Our customers want to stay productive in today’s connected environment. We’ve made improvements to
our smart@ccess customer portal so that they can easily find product information with net pricing and stock
availability at their nearest branch before placing an order - all from their desktop, tablet or mobile phone”,
commented Janina Geraghty, Heatcraft’s e-Business & Communications Manager.
The extensive online product catalogue will include technical documents, installation manuals, brochures,
user manuals and more. Visitors can search by line item or product category and find information quickly
thanks to a new site-wide, multi-faceted search function. The search function will pre-populate as you type
and display a list of categorised results including PDF documents and brochures.
The smart@ccess online ordering system is unique because customers have the choice to either add to
cart straight from the catalogue or create their order through our industry leading project tools. This takes
the guess work out of project estimations and ensures they purchase the right product for the application.
Real time order status updates let customers know when the order is ready for pick up, so they can plan
their day’s travel and eliminate waiting time at the branch. Customers can also consolidate orders and
better plan their job requirements, reducing the risk of forgotten items.
The new additions to smart@ccess join the suite of project tools and account maintenance features which
have been providing convenience 24/7 to Heatcraft customers since the portal was launched in 2012.
Janina added, “The additions have been developed to meet the specific needs of our customers. We
conducted a survey and have responded promptly to their feedback. Heatcraft is focussed on improving the
customer experience and helping our customers improve their productivity."
Heatcraft customers who do not already have a smart@ccess login should contact their nearest Heatcraft
branch today to register.
Tools for WorldSkills
Heatcraft Australia together with CPS Products and Teng Tools is pleased to donate a variety of tools valued at $5,000 to WorldSkills Australia. The tools will be used by National Refrigeration 2014 Winner Beau Kupris as he represents Australia at the 43rd WorldSkills Competition in São Paulo, Brazil on 11-16 August.
Beau is one of 25 WorldSkills Skillaroos that will attend the WorldSkills Competition. The competition takes place every two years and is the biggest vocational education and skills showcase in the world.
In 2015, 59 countries with over 1,200 competitors will compete in 50 skill categories.
When asked how he has been preparing for the event, Beau commented,
“I’ve been doing extra training at Granville TAFE, with Michael McHugh and Brian Mobbs overseeing my work. Whilst the nerves are starting, I’m very excited to be competing. Representing Australia just by doing my everyday job is going to be amazing.”
Beau was thrilled to collect the donation from Heatcraft Vice President, Tom Overs.
“Most of the tools I have been using are dated. I can’t wait to get them back to the TAFE and start using them”.
Heatcraft Australia thanks CPS Products and Teng Tools for their generous contributions.
Lennox expanded Chiller range
Heatcraft Australia has just expanded their range of energy efficient commercial chillers with the introduction of Lennox Aqua4 Polyvalent Air Cooled Chiller and Heat Pump.
“A market comparison has shown that the Lennox Aqua4 is on average 13% more energy efficient than equivalent competitor models for cooling and up to 4dBA quieter than any other 4 pipe system in the Australian and New Zealand market”, commented Mark Esdaile, Heatcraft HVAC Business Manager.
The Lennox Aqua4 is a cost effective alternative to VRF systems that offers simultaneous or independent heating and cooling from the one system. It is especially suited to commercial buildings, hospitals, hotels and public buildings that require different zoning and load requirements.
“The simultaneous demand for heating and cooling during the year is increasingly common. Today’s commercial buildings often include areas dedicated to different functions and have high variable heat loads enhanced by large glass windows.”
The simultaneous and independent cooling and heating is achieved by the use of two independent refrigerant circuits connected by 4 hydraulic pipes. These units are able to satisfy the demand for hot and cold water simultaneously through a system that does not require adjustment due to seasonal loading and is therefore a valid alternative to traditional air conditioning plants with chiller and boiler.
Heating and cooling needs are constantly being balanced to maximise total efficiency of the unit to achieve desired temperatures across the entire circuit, regardless of demand. High efficiency scroll compressors and high efficiency insulated braze plate heat exchangers contribute to the high EER’s. The innovative fan blade design optimises airflow, while low noise versions can be specified which include a fully soundproofed technical casing and low speed on the fan.
Selecting an Aqua4 on your next project can also deliver capital cost savings to the property owner. The need for separate heating and cooling solutions is eliminated, which not only reduces plant size, but also reduces installation time, refrigerant and insulation costs. Ongoing facility management is also simplified.
The Aqua4 can operate in extreme ambient conditions, ranging from -15°C to 45°C. Cooling capacity ranges from 50 to 320 kW, with heating capacity from of 50 to 340 kW.
In addition to the Aqua 4, Heatcraft also range highly efficient Lennox Neosys and Ecolean Chillers. "We understand customers are after reliability and quality” continued Mark. All Neosys and Ecolean Chillers are delivered from our European facilities that conduct extended qualification tests to ensure superior reliability.”
The Neosys chillers incorporate the latest multi-scroll Copeland compressors well-known for their solid reliability and high performance. Neosys also uses a specific and exclusive fan motor design with hybrid ceramic bearings to extend the service life of the motors. Full aluminium coils in cooling versions mean that the units can be installed in light corrosive or seacoast environments without any need for additional pre-treated fins or coil coating.
In a water system, the pump is one of the main energy consumption items. The energy costs of pumping can represent more than 20% of the total energy cost of a chiller. Lennox have addressed this with their eDrive™ variable speed pump technology, present in both Neosys and Ecolean. At full load, eDrive™ automatically controls energy costs via an electronic adjustment of the pump curve. At partial load eDrive™ automatically reduces the chiller pump speed. During shutdown periods, the chiller operates at minimum speed and on starting eDrive™ acts as a soft starter minimising start-up current.
“Customers no longer need to make the choice between a high efficiency version, a low noise or an ultra-low noise version. Neosys can adapt all situations with only one version”, concluded Mark. The Active Acoustic Attenuation System™ uses an electronic control associated with variable speed fans. Neosys can automatically change the speed of all the fans – from 0% to 100% of the nominal air flow – to meet the building load requirements while being noise compliant.

Investing in our Future - An interview with AIRAH 2014 Student of the Year
Heatcraft Australia is a proud sponsor of the AIRAH Awards. In 2014, Heatcraft sponsored the Student of the Year category. Winner, Matthew Web shared his insights into the future of HVAC&R.
What is biomimicry and what lead you to specialise in this area?
Biomimicry, from Greek "bios" (meaning life) and "mimesis" (to imitate) is innovation inspired by nature. It offers designers - in all fields of human endeavour - innovation opportunities to develop new products, processes and systems in a more sustainable way. By studying natural adaptions in great detail, humanity has the opportunity to learn new or alternative strategies in all aspects of human technology. With the rapid development in the biological sciences – particularly in microbiology and genetics – there is an ever-growing body of knowledge from which to gather new ideas. The scope for identifying biological inspiration to solve design problems is virtually limitless.
There are three key requirements to effectively applying biomimicry to building engineering innovation. Firstly, both the design problem and its biological solution must be well defined and understood. Secondly, a suitable characteristic, species or ecosystem must be identified that will enhance the performance. Thirdly, a viable process is required to successfully translate ideas from the natural world to the technological domain. Architecture has taken inspiration from the natural world from its very beginnings. Recently, however, much of the recent focus has been either on aesthetic appeal or directly applying living elements to buildings, such as green walls. Alternatively, I am focussed on functional biomimicry, which practices a translation of biological characteristics to building design – and not necessarily the formal aesthetics. Functional biomimicry aims to understand nature in detail so that the physical, chemical or material essence can be abstracted to the technological domain. By reverse engineering biology in this way, functional biomimicry can play a critical role in improving building performance and occupant comfort.
I suppose that was the attraction of biomimicry for me - alternative solutions and new ideas for building design already exist if we could study and perceive the natural world in a different way. I have always had an interest in the natural world too, and the possibility to combine a study of nature with sustainable design was too good an opportunity to pass up.
We see you are focussing on building facade design. What changes are you advocating here?
There are plenty of opportunities to improve upon existing facade design, which tends - at times - to focus on the aesthetics and has been somewhat isolated from the rest of the building services. In actuality, building facades play a critical role in achieving the desired Indoor Environment Quality desired by occupants while also improving building energy efficiency. In other words, I'm advocating better integration between design disciplines and a more holistic design approach when it comes to facades. I think this is becoming more recognised within the industry. In biomimetic terms, the surface area of an animal isn't designed independent of its heart and blood vessels - they are suitably sized and balanced to provide nutrients to all of the animal's skin as well as adequate cooling and heating abilities to cope with temperature extremes.
When speaking about biomimicry specifically, we can observe the efficiency and effectiveness of skins in nature, which present a vast array of different interfaces that can provide inspiration for new facade ideas. Additionally, natural skins in nature are reactive and adaptive - they do not present one single set of constant properties to the external environment. Skin is a key component in human thermoregulation and acts as the heat transfer interface to the external thermal environment. If the brain’s hypothalamus detects excessive heat gain, sweating begins, promoting evaporation. Hairs flatten against the skin, and warm blood flow to vessels beneath the skin surface (vasodilation) maximises radiant heat transfer. If we can efficiently mimic these characteristics for a building skin, we can design buildings that are more comfortable for occupants and reduce environmental impact at the same time.
The PIXEL building in Melbourne is pretty special. What was your involvement on this project?
The PIXEL building (shown below) is indeed special and represents a state of the art example of what can be achieved in sustainable design with holistic design approach and a willingness to embrace new and innovative technologies. PIXEL achieved a maximum score in Green Star and a LEED platinum rating - the highest score for a new building. I was involved through the design process, working in particular on the energy and daylight assessments with our Sustainability director, Shane Esmore. We tested various options and configurations using simulation software and also calculated the buildings' operational energy consumption, as well as assessing the impact and effectiveness of the original architectural shading design (by Studio 505).
You've done a lot of research, what have been your key findings?
I have done some research - but the industry changes all the time so there is always more to learn! In terms of sustainable design - if we look at the natural world I think we have come some way but there are still challenges (and opportunities) ahead. Nature is inherently self-sustaining and regenerative. Nature runs on sunlight, never follows a linear path of consumption, uses only the energy it needs, curbs excesses and relies on diversity. Even if we partially followed those principles it would move design in the built environment far further down a sustainable path.
With specific reference to my PhD, I've managed to design a type of building facade that mimics animal skin. Tested with mathematical simulations, I've shown that fur can be an effective, lightweight insulator when applied to the exterior of buildings. Fur can also be adaptive by extending and flattening to change it's insulation capability. It can rotate to better capture or block sunlight, depending on the whether cooling or heating is required. Furthermore, I've been able to adapt and translate the principles of heat transfer in living tissue (bioheat transfer) to building facades. Again, simulations have shown that the biomimetic facade can be an effective method to cool (and heat) buildings and maintain thermal comfort, roughly equivalent to hydronic systems. Adding a layer of external fur is a further improvement. This studies exemplify how biomimetic concepts can be modelled and simulated to assess thermal performance and occupant thermal comfort.
A mobilised team of Field Engineers
Heatcraft Australia is uniquely positioned with an experienced and specialised team of Field Engineers across Australia and New Zealand to work with the contractor or consultant to deliver optimal project solutions for them and the end user.
Recent organisational changes at Heatcraft mean that this team is now mobilised and available to travel, where practical with the contractor to discuss options with the property owner. Whether it’s a new equipment installation or upgrade to include VSD or EC fans, the Heatcraft Field Engineers have the knowledge in both refrigeration and HVAC to deliver the best outcome for all parties.
Our Field Engineers are often involved in projects from planning to completion, also offering trouble shooting assistance, pre and post commissioning support.
One recent example is where Heatcraft Field Engineer, Stephen Spiers, worked with customer Arctic Refrigeration on a retrofit of R438A into an existing R22 semi-hermetic refrigeration system that had been operating on a South Australian dairy farm. A substantial leak had occurred on the condenser and the plant had lost approximately 100kg of refrigerant.
Stephen was on hand to offer advice in the way of the oil return. “Oil return is determined by a number of operating and design conditions. Field experience has shown that ISCEON® MO99™ will work with the existing mineral oil in most systems#. In this instance we recommended that some of the mineral oil be removed from the system and an equivalent amount of Polyol ester lubricant (POE) replace it. The system has been operating efficiently since”.
With approximately 140kg of R22 required, the refrigerant alone could have resulted in a cost to the customer well in excess of $20,000 to rectify the situation via replenishment alone. Through this successful retrofit, substantial refrigerant savings were passed onto the property owner.
Technical support doesn’t stop with the Heatcraft Field Engineers. As a benefit of doing business with Heatcraft, customers can also call the Heatcraft Technical Excellence Centre (TEC) anytime from 6am to 7pm AEST, Monday to Friday for product and quoting assistance.
