Residential Air Conditioning
Partnership is in the zone
MHIAA’s service & technical general man- ager, John Bolger, said MHIAA went in search of a local hardware manufacturer for its 4-zone relay model.
“We required a plug-and-play solution and looked for an innovative, cost-effective, quali- ty solution. This solution was specifically de- veloped with the Australian market in mind,” Bolger said.
Bolger said most of the work took place during the COVID-19 pandemic, but the team still man- aged to roll it out effectively.
“Throughout the pandemic we have priori- tised stock availability, service and communica- tion for customer peace-of-mind,” he said.
Mass Electronics is a privately owned, Aus- tralian-based electronics design and manufac- ture group, providing consultancy and new product development services from its facility at Brisbane Technology Park.
Mass Electronics managing director, Mike Miranda, said the company was first contacted by MHIAA in 2019.
“MHIAA were seeking a partner to develop an innovative cost-effective and quality product that would facilitate the simple and efficient con- nection of their multi-zone air conditioning units and locally procured 24VAC dampers, he said.

MITSUBISHI HEAVY INDUSTRIES Air-Condi- tioners Australia, Pty. Ltd. (MHIAA) has formal- ised a partnership with turnkey HVAC solution provider, the Mass Electronics Group (Mass Electronics) to deliver the local relay model for its latest zoning solution, FlexiZone.
Thanks to the MH-4ZRM relay modules (ver- sion 1 and 2) provided by Mass Electronics, Flex- iZone can now be easily integrated into MHI’s ducted air conditioning systems and offers the enhanced flexibility of turning individual zones on or off as needed. Interestingly, versions 1 and 2 were developed in just three years.
Optimise indoor air performance
MOST PEOPLE SPEND more than 90 per cent of their daily lives inside buildings and in today’s COVID-present world, improving indoor air quality for the safety of occupants has never been more important.
While access to outside air is one way to im- prove airflow, many built environments such as offices, hotels, and retail centres rely on recircu- lated air through HVAC systems.
Some HVAC systems operate 24 hours, seven days a week, and as air passes through HVAC dust filters, pollutants such as dust and particles become trapped and progressively clog the filter.
The build-up of pollutants on filters leads to increased backpressure and stress on the sys- tem. It could also form an environment for mi- crobial colonisation to increase and pollute the indoor air.
Regular HVAC maintenance ensures the sys- tem delivers efficient performance in terms of energy consumption and optimal air quality de- livery. It also avoids premature wearing and fail- ure of internal components.
In addition to addressing the mechanical up- keep of systems, HVAC improvements help con- trol the spread of infection in built environments.
There are various environmental factors in

buildings such as temperature, humidity, venti- lation and filtering systems that can influence infection in indoor settings.
To optimise filtration, Australian company Aeris Environmental has developed Aeris Guard Bioactive Filter Treatment which, when sprayed onto HVAC filters, kills COVID-19 on application and reduces colonisation by bacteria
and fungi.
A single application can help control
and prevent the growth of bacteria and mould for up to 12 months.
The filter treatment is also proven to extend the life of treated filters, en- hance energy consumption and im- prove airflow by up to 300 per cent.

An ideal HVAC filtration solution is to have this filter treatment applied to filters which are then used as pre-filters for HEPA filters.
The pre-filter extends the life of the more ex- pensive HEPA filter, which in turn does not allow the transmission of droplets carrying the COV- ID-19 virus.
Fixed monitoring devices that offer live time recording, analysis and alarming, or that are connected to Building Management Systems (BMS) can help monitor some limited aspects of indoor air quality.
Appropriately qualified contractors can also help to keep track of indoor air performance.
