innovation

A consistent leader in electronics, Toshiba is committed to delivering the higheststandards of quality and innovation in all of the industries in which the company is amajor player.

These principles are clearly demonstrated in its air conditioning division, whereToshiba continues to develop market leading products for both commercial andresidential customers.

1875 Toshiba established as a pioneer of Japan’s technology industry.

1957 Toshiba enters the air conditioning business.

1969 Toshiba introduces the first portable units.

1977 Toshiba is first to introduce electronic control for air conditioning units.

1981 The first inverter technology is launched by Toshiba.

1988 Toshiba is first to introduce the twin rotary compressor.

1999 Toshiba is the first air conditioning manufacturer to launch a full range of unitspurpose-designed for use with non-ozone depleting refrigerants.

2000 The most advanced inverter-driven residential units are introduced. Electricityconsumption by air conditioning units is now at its lowest, with COP betweenthree and more than five.

2001 A new generation 2-pipe VRF system is launched: the Modular Multi.It is not only outclassing all other VRF systems in terms of performance, it isthe only VRF system that is designed specifically for R407C. Additionally it canintegrate an active leak-detection system.

Toshiba is committed to designing and manufacturing products in the mostenvironmentally friendly way possible. Toshiba will not be satisfied until itscommitment and record on protecting the natural environment are unmatched.

■ R407C only■ Highly energy-efficient system■ Compact design to reduce waste■ Minimisation of electromagnetic harmonics■ Intelligent leak detection system optional

ncy

HFCs (e.g. R22) are being phased out to prevent ozone depletion and inducedGlobal Warming.

To ensure serviceability of installed equipment and in line with present and futurerestrictions, Toshiba offers only R407 VRF systems – providing long-termdedication to customers.

Raising your safety standardsThe newly enforced EN378 lays down maximum exposure limits for leakage.Emphasis is being given to protect permanently manned rooms. Non-compliance implies legal and financial liability for businesses. Toshiba pioneersagain by developing leak detection accessories integrated within the controlsystem, hence respecting both staff and businesses. This option consists of roomsensors – positioned in permanently manned rooms – connected to a simplePCB to be placed on the inverter outdoor unit.

Energy efficiency: the greatest adaptability to load changes Keeping running cost at the lowest:■ Proportional control starts as low as at 10% of nominal load■ Up to 135% diversity■ Precise temperature control at 0.5˚K■ More efficient newly developed 4-sided heat exchanger and blower room

Minimisation of electromagnetic harmonics■ DC reactor reduced harmonics■ 2-in-1 compressor pack of each module reduces harmonics by 50% on a 10 HP,

up to 88% in a 46 HP system

The most compact and quiet VRF system ever■ Volume, weight and number of components reduced by more than 25%

= Reducing waste■ The most compact 10 HP on the market■ New development reduces operating noise to 58dBa on a 10 HP unit

a new technology-packed system

Unchallenged performances through cutting-edge technology and state-of-the-art design

■ Up to 40 indoor units, up to 46 HP■ 30m lift between indoor units■ More capacity and more precise control■ Total design flexibility

– Smallest installation area– Infinite piping possibilities

Intelligent Power Drive Unit (IPDU)The latest Inverter technology enables:■ Combination of up to 5 outdoor units (46 HP)

without any function unit■ Always the most precise proportional control

(from 10%)■ Integration of pressure and heat sensors in the

indoor units■ The most intelligent oil balancing control

A-1 – Advanced oil separator in each outdoor unit to prevent the rapid fallof oil level at system start

A-2 – Regular return to compressorA-3 – Oil-level balancing between outdoor unitsB – Compressor pack maintains required oil levelC – Intelligent oil retrieval system (once per hour minimum and during

low load operation as well)= Achieves the industry ’s smallest installation area= Up to 40 indoor units – from 8 to 46 HP in one piping circuit= Up to 30m lift versus 15m for old generation VRF systems= Precise capacity control along the pipe run= No restriction on piping design (header after header…)

A fully redesigned outdoor unit

Pressure and heat sensor control in each indoor unit

Intelligent sensors combined with the intelligent inverter control eliminatescapacity differences between indoor units.

With this technology an indoor unit will always operate at optimum capacitywhatever its position on the piping circuit, thus simplifying design. This also allowsusing a line branching or even a header branching after a header branching.

■ A newly developed stealth fan enables greater airflow with lower noise

■ A new bell mouth gives efficient air discharge with lower noise

■ Separation between compressor chamber and air discharge to place a more efficient 4-sided heat exchanger

■ The compressor is located on a sliding tray to assist servicing

= Improves heat exchange ratio (COP)= Improves noise level = Improves serviceability with an immediate access to major components
