The Toolshed

1 Inspired by nature

To be launched at ARBS, the new Midea GAIA split system boasts an innovative “OxygenFresh Air Exchange System”, an I-Clean self-cleaning function, and “Breezeless Technology” with HEPA filtration and smart energy-saving features.

“OxygenFresh Air Exchange technology can introduce up to 60m³/hr purified fresh air from outdoors, letting staleness out and freshness in,” Midea says.

“I-Clean six-step self-cleaning at up to 56°C temperature deeply purifies the evaporator, providing a fresh and clean air supply.

“Breathless Technology allows 7,928 mini-holes with hourglass structure transforming the strong airflow into thousands of tiny strings of air that give the softest touch of cooling.

“The all-new air duct and windwheel design allows airflow to pass smoothly with an operating noise level as low as 19.3dB.”

Midea Appliances Australia says the GAIA product is for those who demand the “real nature-like air experience”.

The GAIA is offered in three operating power options: 50 per cent, 75 per cent and 100 per cent.

“In Eco mode as little as 1.29kWh per night (eight hours) is consumed,” Midea Australia says.

2 “Can do” mindset from S-5!

S-5! has introduced the CanDuit clamp, designed to secure and support chases and raceways, cable trays, gas piping, condensate lines and other round-shaped objects to metal roofs. It can be used in combination with other S-5! clamps or brackets, including the GripperFix utility mounting system.

Made from electro-zinc coated steel, the CanDuit clamp features two halves that clamp around the pipe or conduit with an EPDM liner pad, which protects against abrasion, and a threaded M8 stud that allows for attachment to S-5! Products. This facilitates securement without scratching, corrosion or other damage to the roof, S-5! says.

The CanDuit can be used in both residential and commercial settings for a range of applications including condensate drainage, electrical, solar and plumbing for gas or water. It is available in 14 sizes, with outer-pipe diameters ranging from 20mm (0.79") to 117mm (4.6").

Adjustability within each clamp enables minor size adjustment to secure most conduit and other piping. ■

3 The new black from Inaba Denko

“Inaba Denko has launched a new range of internal and external PVC capping that ensures air conditioning refrigeration pipes are protected with an aesthetic and professional finish,” the company says.

“The Slimduct traditional colours of ivory and white already offer unique advantages to the installer.

“Slimduct Black is a new important addition to the product range. Its quality is assured under extreme Aussie conditions, especially against UV. It is perfectly matched to dark-coloured exteriors. Black is extremely popular in the UK, where black duct has outnumbered the traditional ivory and white colour in the past five years.

“Slimduct adds beauty to the façade as an architectural feature, with its slim light-weight profile and ease-of-use to install. It is made of rigid PVC capping offering impact resistance. It is fade proof and flame retardant.”

The company says Slimduct is a labour-saving alternative to custom-fabricated line-set ducting options.

“It is easy to install and field configure to any orientation, it is easily accessed,” the firm says, “and line-set maintenance can be performed quickly and effectively.”

Brown and grey profiles will be available soon.

Available through all Kirby HVAC&R branches.

4 V8 Filter power

Daikin Australia has released its MERV 8 Filter – BAF552A160.

“This high-performance filter is designed to be easily retrofitted into VRV FXF(S)Q-AVM and SkyAir FCA-C(A)VMA Round Flow Cassettes to enhance their air filtration capabilities, improve indoor air quality and provide building occupants with healthy, comfortable and productive indoor environments,” Daikin says.

“The Minimum Efficiency Reporting Value (MERV) rating system measures the performance of air filters. With a rating of 8, this filter is able to more effectively reduce common indoor air pollutants such as dust, pollen, dander and lint.

“Tested by the Daikin Technology and Innovation Centre, the new MERV 8 Filter is proven to effectively remove up to 70 per cent of 3.0–10μm particles and 20 per cent of 1.0–3.0μm particles.”

Daikin says the MERV 8 filter can replace an existing cassette’s prefilter, with efficiency maintained for up to six months.

5 Daikin in the great outdoors

Daikin Australia has launched its new Slimline Outdoor Air Processing unit (FXMQ-AFVM).

“This new unit can be connected to both Daikin Heat Pump and Heat Recovery VRV outdoor units,” Daikin says, “thus offering a full Daikin HVAC building solution comprising comfortable cooling and heating, required ventilation and centralised controls.”

Daikin says the unit’s ability to pre-condition outdoor air to a target room air temperature reduces the air conditioning load and improves air temperature and humidity control.

“The addition of a built-in drain pump with 700mm lift and silver ion anti-bacterial agent box prevents the growth of mould and bacteria in the drain pan,” the firm says. “Indoor air quality can be further optimised with the unit’s compatibility with MERV 8 and 14 filters.”

The company says the ability to connect fan coil units for air conditioning and outdoor air-processing units to the same refrigerant line offers enhanced design flexibility, space saving and a significant reduction in total system costs.

6 Midea’s split and slim

Midea is launching its MSP and HSP Duct units at ARBS.

“The new Midea MSP slim-line and the split-design HSP duct indoor unit offer reliability and high efficiency with ease of installation and energy savings,” Midea says. “With split design structure, the HSP duct indoor unit can easily be separated into a coil part and a fan part. And it can be reassembled within a ceiling for installation.

“The new compact 7kW outdoor unit takes approximately 22 per cent less footprint [than average],” Midea says. “One installer can carry it easily. This is especially useful for renovation and retrofits, saving on installation, maintenance and labour costs.

“With a durable R32 full DC inverter duct split using GMCC R32 twin-rotary compressors offering highly efficient heat transfer and refrigerant cooling with inner-groove high-efficiency tubes, the unit is optimised.

“Compared with fixed-speed air conditioners, full DC invertor air conditioners can reduce approximately 55 per cent power consumption in a year.”

7 Blauberg gets Civic

Blauberg Ventilation has introduced Civic, a new range of German-designed wall-mounted ERV units.

“COVID-19 and the 2019–20 bushfires raised major issues with insufficient quality ventilation in school classrooms and offices,” says the company. “Bad air quality, high humidity levels, high CO2 concentration, and low oxygen levels create a long-term unsafe study and work environment for occupants.”

Some public health authorities have recommended 4–6 air changes per hour, and AS 1668 indicates that the required ventilation to be designed into an active HVAC system for classrooms is 12L/second/person.

Blauberg says the Civic meets these guidelines by providing filtered fresh outside air, rather than filtered recycled air, through a heat exchanger to minimise energy loss. H11 HEPA fresh air filters are included to maximise indoor air quality and safety. And according to Blauberg, with a very low noise level of 24–25 3m dB(A), the Civic units provide a pleasant indoor environment.

Manufactured in Europe, the Civic units can be fitted with Blauberg EC motors for low power consumption. ■
