Air conditioning technology
TOSHIBA air conditioners depend solely on inverter technology.
The inverter technology is an advanced technology which is used in many state-of-the-art air conditioning systems to improve the efficiency and power of the system. Essentially, an inverter is an electronic control system which continuously adapts the compressor speed in the air conditioning system along an infinitely variable range, instead of simply switching it on or off. This enables the temperature to be controlled more precisely and more efficient cooling or heating of the room.
Inverter technology
All main components used in TOSHIBA products have always been developed and produced in-house. The robust single or twin-rotary compressors work with 100% inverter technology in all units, meaning only so much power is produced through the electronic speed control of the compressor as is currently required. This saves energy, as the system operates for the majority of its operating time in so-called part load operation – in the case of a reasonably dimensioned air conditioning system, this is at least 80% to 90% of the operating time. In addition to the power, and therefore the money, saved, the inverter technology also provides benefits in terms of comfort: Temperature fluctuations are avoided and we can enjoy a uniform and comfortable climate!
Energy efficiency:
Inverter air conditioning systems are more energy-efficient than conventional air conditioning systems. Since the compressor is not being constantly switched on and off, the system needs less energy to maintain the desired temperature. This results in lower energy costs and reduces energy consumption.
Constant temperature:
Inverter air conditioning systems are able to ensure that the indoor temperature is maintained more accurately and constantly. They prevent temperature fluctuations which may occur in conventional air conditioning systems when the compressor is switched on and off.
Faster cooling/heating:
Inverter air conditioning systems are able to bring the room to the desired temperature more quickly, since the compressor operates at a variable speed, rather than switching on and off at fixed intervals.
Longer service life:
Since the compressor is not under constant stress in inverter air conditioning systems, this can contribute to a longer system service life, as wear is reduced.
Environmentally friendly:
Due to the reduced energy consumption, inverter air conditioning systems play a role in ensuring lower greenhouse gas emissions and are more environmentally friendly as a whole.
Reduced noise:
Inverter air conditioning systems are generally quieter, as the compressor does not run at full power when the desired temperature has been reached.
Electronics
In order to be able to realize the optimum ratio of power input and output, even with very varying requirements, TOSHIBA operates with two modes in the control electronics: PAM (pulse height modulation) and PWM (pulse width modulation). PAM mode is for high loads, while the inverter switches to PWM mode in the case of low loads. Only TOSHIBA has integrated both modes in its control electronics and therefore achieves enormous energy savings.
Motor
The drive for the compressor is fitted with a motor with a changeable rotational speed. Permanent magnets have been used for the poles of the DC motors, and the role of the rotational speed control is to determine the relevant compressor rotational speed needed depending on the load.
Compressor
TOSHIBA uses twin-rotary compressors in almost all units. These twin-rotary compressors consist of two rotary units which rotate counter to one another, increasing mechanical stability while minimizing vibrations. The speed of the compressors can be excellently regulated, even when power requirements are low. Another significant benefit of the compressor is the low level of noise it produces.
