Latest News From Toshiba
Earth can hardly wait for a change in the atmosphere. Nor can we.
By making airconditioning supremely energy-efficient, quiet, easy
to install and cost-effective, Toshiba aims at the heart of growing
global pollution.
TOSHIBA AIR CONDITIONING'S HISTORY
The Toshiba story is a fascinating one, featuring unbending dedication to quality and unceasing innovation. It starts some 100 years ago, when Japan's reputation as a closed, enigmatic society was being broken down by a hunger for the industrial age. Electricity was the new wonder, and in 1899 Japan's first manufacturer of electric lighting equipment adopted the name Tokyo Electric Company.
Around the same time, one of Japan's largest manufacturers of heavy electrical equipment adopted the name Shibaura Electric Company. When the two companies merged in 1939, the Tokyo Shibaura Electric Company was set to become a household name across the world, although the 'nickname' Toshiba was not adopted officially until 1978.
COMBINING TECHNOLOGY WITH COMFORT
The true quality of residential air conditioning goes well past our capacity to control and direct air filtration. There are many stages and additional functions, such as pre-treatment, removal of fine particles and allergens from the air. Ultimately, the Daisekai model includes a beneficial shower of negative ions and electrostatic purification.
Toshiba has anticipated many legislative regulations on the control of refrigerant emission into the atmosphere, and has pioneered solutions that only a few can claim similar technology supremacy. For example, Toshiba was the first air conditioning manufacturer to launch a product range with non-ozone depleting refrigerant R410a back in 1999.
TOSHIBA AIR CONDITIONING TAKES SHAPE
After W.W.II Japan enjoyed rapid economic growth, and its society and industry developed on the American model. Based on American products, Toshiba made its first air conditioning units, and introduced improvements throughout the 1950s. By 1961, they were able to introduce the world's first split units. Its new role as innovator, continued with the introduction of Japan's first rotary compressor in 1968. By the 1970s, Toshiba had arrived as a modern multinational company, with a varied product portfolio and world-wide manufacturing sites. In 1978 the name Toshiba Corporation was formally adopted, at the same time as the first computerized compressor units were being introduced. Further advances included the world's first inverter unit in 1981 and the world's first gas fired inverter and twin rotary compressor in 1988.
Toshiba is committed to delivering the highest standards of quality and innovation across our air conditioning product range and services. For more than 40 years Toshiba has led the world in creating better air conditioning; setting new standards in comfort, ease of use, energy conservation and climate control.
R-410A REFRIGERANT - ENERGY EFFICIENT
Toshiba Inverter Air Conditioning encompasses a comprehensive range to suit residential and commercial applications. Toshiba Inverter Air Conditioning systems provide excellent energy efficiency, are reliable, and run on R410a non-ozone depleting refrigerant.
INVENTOR OF THE INVERTER
KEY POINTS
DC Hybrid Inverter quickly achieves and maintains room temperature.
High Energy Savings due to accurate digital controls.
Exceptional reliability and operation due to elimination of compressor ON/OFF cycle.
Twin rotary compressor ensures smooth linear rotation of the compressor for quite running.
When Toshiba Invented the Inverter technology in 1981, Toshiba has continued to maintain a comfortable technological advantage over many competitors . The development of the and new exclusive to Toshiba DC Hybrid Inverter system has reaffirmed this capability to innovate and maintain the technology advantage on what is a rapidly growing air conditioning market.
The Toshiba DC Inverter digitally controls the capacity supplied by the air conditioner, by modifying the electricity supply current frequency or intensity, to insure a smooth rotation speed or capacity of the compressor. This allows precise matching of the cooling or heating capacities to the actual operating conditions. When the room temperature is set far from the set point (required temperature), the DC Hybrid Inverter operates at maximum capacity to ensure the set temperature is reached quickly.
Once the desired temperature is has been reached, the Inverter precisely adjusts the capacity to maintain the temperature close to the set point.
CONTROL LOGIC
At start up, the pulse Amplitude Modulator (PAM) sets the compressor at maximum power, providing fast cooling or heating as required, to achieve the desired room set temperature. The Pulse Width Modulator (PWM) engages automatically to ensure the desired room temperature is maintained evenly. This results in savings in power consumption which means energy cost savings.
ZERO OZONE DEPLETION
The Toshiba range of products includes a wide choice of units that operate on the R-410A refrigerant. R-410A is a non-ozone depleting refrigerant that meets the strict requirements of the Montreal Protocol. This protocol required a move away from ozone depleting refrigerants to those which have a Zero Ozone Depletion Potential, or ODP as it is referred to within the Air Conditioning industry. In 1999 Toshiba was the first air conditioning manufacturer to launch a product range with non-ozone depleting refrigerant.
R-410A is a higher efficiency refrigerant than others on the market. In fact, R-410A is up to 12% more efficient than R-407C, and up to 16% more efficient than Freon R-22.
