1 DC INVERTER DUCTED AIR CONDITIONERS

2 DC Inverter Ducted Air Conditioners Technology. With over 5% of revenue invested in research and development programs, Hitachi has developed world leading technologies including some of the most advanced air conditioning systems currently available. Reliability. For over 25 years Hitachi has been providing Australians with reliable, efficient air conditioning products for both residential and commercial applications. Easy Installation. Compact, lightweight and with flexible piping and wiring, Hitachi s DC Inverter Ducted units allow easy installation in any environment. R407C. Be confident in knowing that your Hitachi Ducted DC Inverter system uses a refrigerant that is non-toxic, non-flammable with zero ozone depletion.

3 In a climate as diverse as ours you need a reliable temperature control system that responds to the environment quickly and efficiently. With over 30 years worldwide experience Hitachi has gained a reputation for quality, reliability and industry leading technology. DC INVERTER DUC TED AIR CONDITIONING

4 Motor efficiency (%) DC motor AC motor Motor efficiency (%) DC motor Efficiency increased by 40% (motor input halved) AC motor Energy Efficient Revolutions per minute DC Compressor Advantage Revolutions per minute DC Fan Motor Advantage POWER SAVING DC INVERTER Inverter technology allows a room to reach the required temperature more rapidly and up to 30% more efficiently than Constant Speed Systems. Inverter technology also eliminates the frequent stopping and starting often required by standard systems in order to maintain consistent temperature conditions. Rather than starting the motor up and stopping it when the desired room temperature is reached, Hitachi Inverters adjust (increase/decrease) the speed of the compressor in order to maintain the desired temperature in the most efficient manner. DC COMPRESSOR AND FAN MOTOR The permanent magnet motor featured in the DC compressor maintains magnetic current without the need for a constant source of electricity. This ensures the motor suffers less ambient energy loss, delivering 10% greater efficiency than equivalent AC inverters. The outdoor fan motor also utilises a DC motor to further improve system efficiency. PAM SYSTEM The Hitachi Power Active Model (PAM) Inverter System suppresses electrical distortion to minimise power losses to less than 1%, thereby maximising system efficiency. Heating performance is particularly improved to ensure efficient performance even when the ambient temperature is -15 C. NEW CBC (CONDENSER BEST CONTROL) SYSTEMS New CBC 1 achieves high-efficiency cycles and lower energy consumption. Room temperature Set temperature Time DC inverter UTOPIA Current machine with constant speed Room temperature High power information In the case of existing machines with constant speed, repeated turning on and off wastes energy Energy-saving operation Time Current machine with constant speed DC inverter UTOPIA Size of heat exchanger has been increased. By controlling the electronic expansion valve with a microcomputer, the cooling cycle is optimised. Performance improved by placing the sub-cooler on the wind ward. Set temperature controlled depending on outside air temperature. 1. Patent Pending

5 Low noise fan motor Quiet Operation New fin with lower air resistance Optimised Compressor rotor (with Neodymium magnet) PEACE AND QUIET The beauty of Hitachi s DC Inverter systems is the quiet operation which can be attributed to innovative noise reduction technology. The result is a hard-working, efficient system that is amongst the quietest on the market. Electromagnetic noise reduction The newly designed fin and bell mouth combine to minimise resistance for a smoother airflow through the New bell-mouth for smoother airflow Air-flow For compressor motor, before changing the rotor unit. The Delta-shaped edges on the fan deliver more efficient air movement allowing for a smaller fan and minimised noise levels. Through advanced design developments, both in the fan motor and the compressor rotor, electromagnetic noise New bell-mouth Noise Frequency (Hz) common in other inverter systems is significantly reduced.

6 Ergonomic Design SLEEK, SPACE-SAVING DESIGN The compact, lightweight design of Hitachi s Ducted DC Inverter systems provide increased flexibility when it comes to positioning the outdoor unit. The subtle vents, located throughout your home, quietly and efficiently deliver cool or warm ducted air throughout the building to maintain a constant temperature, while the indoor unit can be easily installed out of sight, in the ceiling or under the floor. INTELLIGENT CONTROLS Hitachi style flows through to the sleek, LCD wall-mounted controls which reflect the sophistication of the DC Inverter systems. While an optional Wireless Remote Control is available for those who want the ultimate in convenience. ZONING Hitachi s ducted units can be programmed into different zone areas. You can choose to cool or heat only the selected zones that are being used resulting in far greater efficiency. R407C REFRIGERANT The new range of Hitachi inverters feature the refrigerant R407C. While achieving similar energy efficiency levels of previous refrigerants, R407C is non-toxic, non-flammable with zero ozone depletion. IDEAL REPLACEMENT UNIT In many cases existing wiring, circuit breakers and refrigerant piping can be re-used due to the unique features of Hitachi s DC Inverter Ducted Units (contact Hitachi for more details). 5 YEAR WARRANTY The 5 year warranty on parts and labour is your guarantee of the finest quality and customer support.* * 5 years domestic application. 1 year commercial application.
