Our company will release home-use multi inverter air conditioners (14.1kW type) adaptable for up to 8 rooms for North American market from July 31.
In order to respond to such needs, the multi air conditioners for buildings have been used for housings in the past but there have been such problems as the refrigerant noise and the big size of outdoor unit for home use. Therefore, we developed the home-use multi inverter air conditioners adaptable for large-size houses with many rooms. Besides, to cope with the increased connections with indoor units, the simplification of installation was improved by adopting the function to check the faulty wiring automatically and changing the connecting part of all pipes to flare connection system which requires no welding work. Our company will strive to expand business by strengthening the lineup of multi air conditioners suitable for the individual air conditioning system and positively introducing the excellent energy-saving performance in North America. Also, the maximum pipe length of 70m between outdoor unit and indoor units and the largest height difference of 30m have been realized to suit for the houses where the installation space for outdoor unit is limited. Maximum 3 Branch Box unit can be installed and maximum 3 indoor units can be connected with one Branch Box unit. Vertical, horizontal and ceiling-hung installation is possible and also the installation in such small space as under floor or under roof is possible. Also, in spite of the compact size, the new product realizes the industry's top class*1 energy-saving performance and contributes to the reduction of power consumption by adopting heat exchangers arranged in 3 rows and DC twin rotary compressor.
A schedule management function to be able to set one week operation schedule of each indoor unit individually was adopted. A function to check automatically the faulty wiring or forgotten wiring between outdoor unit, Branch Box unit and indoor units was adopted. As a flare connection system which has no cause for concern of inflammability like welding workis adopted for the pipe connection part between outdoor unit, Branch Box unit and indoor unit as in the case of conventional home-use air conditioner, simple and safe installation work has become possible.
Eco-Friendly Renesas Toward Green Society Smart Grids Green Systems Green Applications Green Devices Further efforts to save energy are essential to overcome the environmental issues facing us.

In spite of the compact design, the new product contributes to the reduction of power consumption by realizing the industry's top class*1 energy-saving performance. The function works before the test operation and, if there is any abnormality, the error code is shown on the circuit board of outdoor unit.
One essential point in achieving this will be reducing wasted power at the system level through efforts to make control as efficient as possible. In North America, a central air conditioning system to cool and heat all rooms centrally is predominant for household, but recently, the demand for energy-saving individual air conditioning system to control air conditioning of each room independently is expected to increase. As key components of many products, semiconductor devices have a big part to play in this area.
Especially, for large-size housings, the needs for multi room air conditioning system which can control cooling and heating for all rooms individually with one outdoor unit are increasing. Also, as the full-dot LCD screen with backlight is equipped, the visibility of texts and figures has improved. By this function, the false installation work due to the increase of connection of indoor units can be reduced. Both hardware innovations and software design technologies play important roles in contributing to the realization of more environmentally friendly products. To ensure the stable operation of large-scale power systems, many countries are actively promoting the construction of smart grids , a new type of power distribution grid system employing information technology (IT). One point to keep in mind regarding this method of reducing standby power consumption is that the device used for control continues to consume power. It enables the power consumption of the device to be reduced dramatically, either by halting operation of all blocks that are not essential or by switching to an extremely low operating frequency.
Recent semiconductor products offer the user a variety of low-power modes to select from to match the operating conditions. It is particularly important to increase the energy efficiency of motors, which convert electric power into motive force, and inverters are ideal for this purpose. An inverter works by converting the commercial AC power supply output into DC, generating an AC voltage from the DC voltage, and using the output to drive a motor. For example, if a piece of equipment is connected directly to a 100 V commercial power supply with a frequency of 50 Hz or 60 Hz, an inverter can be used to control the voltage amplitude and frequency, and the drive phase, making it a highly effective technology for reducing the operating power consumption.

2) Higher Energy Conversion Efficiency and Fine-Grained Control: Details of Inverter Control Fine-grained inverter control loop (Click to enlarge) In applications such as factory automation equipment or household appliances, it is necessary to manage factors like temperature, humidity, rotation rate, and flow volume in addition to time.
An air conditioner, for example, uses a motor to turn the compressor and performs control to bring the indoor temperature to the setting value by using the operating principle of a heat pump.
A sensor constantly monitors the indoor temperature, and the temperature is raised or lowered toward the target value by controlling the operation of the motor and the control valves.
Inverter control is a technology that provides free control over the voltage and frequency of the power supply.
Before the advent of inverter technology, the output of the commercial power supply, without modification, was generally used to drive motors and the like. Fine-grained control was not possible and this imposed limits on the degree to which efficiency could be improved.
Most electrical products, such as household appliances, home electronics, and personal computers, incorporate a power supply circuit that converts the AC into direct current (DC). It enables use of a higher switching frequency and smaller coils, making it an effective way to make the power supply more compact.
Using a digital control system for the power supply means that a processor or digital signal processor (DSP) can be used to perform the necessary operation processing and allows support for a variety of control methods simply by making changes to the software.
However, since UPS systems use internal batteries to store power, they are constantly performing AC to DC to AC power conversion.
This has spurred demand for complex control systems that cannot be implemented with conventional control methods. The function of a power supply is efficiently to convert power from a commercial power source or battery into electricity in the required format.
If the efficiency of the conversion can be improved even a little, this translates directly into a reduction in power consumption. The digitizing of power supplies opens up many new possibilities, including high efficiency with flexible control by software and centralized control of large-scale power supply systems through the use of communication functions.
