Daikin’s plug-and-play AHU
1
Daikin has introduced air handling units (AHU) with productintegrated controls (AHU-PIC), which the company describes as “an industry-leading IoT-ready air-handling unit offering ultimate control straight out of the box”.
The dual-barrier coating on the unit’s heat exchanger and facial surfaces is designed to prevent dust and greasy dirt from adhering to it. Mitsubishi Electric says this not only helps the unit stay cleaner for longer, but also makes cleaning the unit easier.
“Delivering more efficient, technologically advanced and highperforming buildings is becoming an increasingly important consideration in the construction industry,” Daikin says. “Building owners, builders and consultants are placing a greater focus on specifying products that contribute to their smart building credentials while minimising risks around systems integration. “Now, AHU-PIC takes air handling units to a whole new level, delivering ultimate control into the hands of building owners thanks to a configurable integrated control system that provides deeper insight into building performance, with advanced systems integration and connectivity requiring fewer people and processes.
The MSZ-AS90VGD-A1 offers optional wi-fi control, connecting the unit to a user’s smartphone, tablet or online account, and allowing them to control the unit via internet. This can be used to heat or cool a room before the user arrives home.

“Because no brazing or flaring is needed, HVAC refrigerant lines can be securely connected in various environments saving you time and money,” says the company.

“Whether you call it upper-air UVGI or upper-room GUV, this is the very concept we started with, back 60-plus years ago, when approached about building fixtures to use in rooms, with the potential for person-to-person airborne transmission of infectious pathogens,” says EcoHVAC.
“Getting a secure connection is easy, thanks to the sight window on each fitting,” says RectorSeal. “To use, simply push the fitting into the correspondingly sized lineset, and relax.”
The STBF-24 model is designed for high bay applications where a minimum mounting height of 3.8m is possible, such as airport concourses, gymnasiums and conference centres.
Both systems use UV-C lamps and reflectors and a fan and louvered exterior to provide UV-c intensity into the upper air of a room while confining the UV-C energy to the unoccupied space above the floor.

Mitsubishi’s plan for open plans
“Delivering clean, fresh and healthy air is a priority for us,” says Mitsubishi Electric Australia National Product Manager Atesh Mani. “The AS90 uses a built-in anti-allergy enzyme filter, which works to trap allergens such as mould and bacteria by using enzymes to decompose them. 8

FLIR Systems has released its latest T-Series high-performance thermal camera, the FLIR T865.
FLIR says that with ±1°C or ±1 per cent temperature measurement accuracy, professionals can more confidently inspect and assess equipment health regardless of the time between inspections or changes in environment conditions.
Mitsubishi Electric Australia has introduced a new 9kW wallmounted split system designed for large open-plan spaces that can often be hard to temperature control from a single unit. The MSZ-AS90VGD-A1 is designed for year-round service in large open-plan living areas thanks to its relatively large capacity. It also includes features such as advanced air filtration, dual barrier coating, and long airflow operation.
FLIR T character
“Built for electrical condition and mechanical equipment inspection, and for use in research and development applications, the T865 provides ±1°C or ±1 per cent temperature measurement accuracy, a wider temperature range between -40°C to 120°C, and more on-camera tools for improved analysis,” FLIR says. “A free three-month subscription to FLIR Thermal Studio Pro and FLIR Route Creator, and a one-month subscription to FLIR Research Studio is included with purchase.

“Refrigerant leaks can be a painful situation during an installation that offers limited installation space, hard‑to‑reach linesets, and installations where it’s challenging to braze and flare. Why take a risk brazing and flaring when PRO‑Fit connections make the task faster, easier, and equally secure? Every time you light your torch is an opportunity for a refrigerant leak to develop. Often, one that you won’t discover until you are pulling a vacuum on the system.” RectorSeal says that, when properly installed, PRO-Fit fittings provide a unique, leak-proof sealed connection. The double O-ring sealing design creates a secure high-pressure gas seal that helps prevent connection leaks caused by galling, vibration, pulsation, and extreme temperature changes that can affect HVAC linesets up to 60 bar.
“With a renewed demand for these systems over the past few years, the aesthetic requirements for many applications, combined with larger shared spaces has led American Ultraviolet to update its upper-room GUV offerings to fit this need.”
The STBF-12 model is designed for applications such as classrooms, offices and conference rooms. It has a single mount point, allowing it to be installed as a single unit or an array of units to cover larger spaces.
Flame-free fittings
According to RectorSeal, PRO-Fit Quick Connect push‑toconnect fittings efficiently connect copper and coated aluminum linesets for unitary and ductless HVAC units.

“AHU-PIC arrives onsite with controls and sensors factory-fitted, pre-programmed and tested, ready for immediate installation. The integrated control is easily connected to existing BMS, BACnet or ICN platforms, and is configurable for internet connectivity without the need for a BMS contractor onsite. With less trades onsite for installation and connection, the WH&S risk is minimised and construction timelines are accelerated.”

“This is the largest capacity model in our domestic range, making it ideal for families who are spending more time indoors, whether that be for study, working from home, or keeping warm during the cooler months. This unit provides ultimate comfort with operation modes such as long and wide airflow, helping to provide a more even air conditioned experience.”

“By reducing measurement variation, companies can reliably prevent equipment breakdowns and outages in utility substations, power generation and distribution, data centres, manufacturing plants, or facility electrical and mechanical systems. For those in research and development, the improved accuracy provides the temperature measurement detail required to eliminate any guesswork in research, science, and design that uses the visualisation of heat.” Go to www.flir.com/t865. ■
