Toshiba Inverter Technology

An inverter air conditioning unit increases or decreases the room temperature by automatically adjusting the compressor speed. Once the room is sufficiently cooled or heated, the inverter automatically reduces the compressor speed. This saves energy and minimizes temperature fluctuations within the room.

Thanks to inverter technology, the compressor only runs as fast as needed. As the compressor does not need to start and stop constantly, the lifespan of the air conditioning units is extended. Toshiba was the first manufacturer to introduce inverter technology in air conditioning units in 1981. Since then, this technology has continued to evolve and improve.

Diagram Description: A graph showing temperature over time. It illustrates a rapid cooling phase, followed by fluctuations around the desired temperature, and finally stabilization. The graph contrasts this with a hypothetical system that might overshoot or undershoot the target temperature more frequently.

Toshiba's inverter regulation uses two different types of drive for the compressor: Pulse Width Modulation (PWM) for high efficiency, especially at partial load, and Pulse Amplitude Modulation (PAM) for high output, allowing the desired temperature to be reached quickly.

Benefits of Our Inverters

• High Performance with Low Power Consumption: Digital and Super Digital Inverters provide an optimal combination of high performance and low power consumption. These technologies offer impressive power and maximum comfort, minimizing energy consumption under all conditions.
• Extreme Adaptability: Digital and Super Digital Inverters feature exceptionally compact casings. Utilizing advanced technologies like hybrid DC control and twin-rotary compressors, they ensure adaptability covering usage from -27°C to 52°C.
• Quiet Operation: The Toshiba twin-rotary compressor, at its core, consists of two counter-rotating discs. This construction, with maximum mechanical stability and minimal vibration, guarantees quiet operation for all Toshiba devices.
• Stable Room Climate: Through intelligent control of the inverter system, the modulation width is smoothly regulated between 20% and 100%. This precise regulation ensures a stable temperature without frequent on/off cycles.
• Individual Settings: Special modes such as "Soft Cooling" or "Dual Setpoint" provide personalized comfort settings. Whether for maximum comfort or efficient energy management, Toshiba facilitates the adaptation of desired functions.
• Automatic Mode Change: To quickly reach the desired temperature, the PAM mode is active for high power output. Once the temperature is reached, it is maintained with minimal energy consumption (PWM mode).
• Variable Control: Compressor speed, and thus unit output, can be regulated almost steplessly in 0.1 Hz increments. This allows for precise settings and optimal energy utilization.

Efficiency Indicators

The efficiency of air conditioning systems and heat pumps is expressed by their performance coefficients.

Performance coefficient is the ratio of cooling or heating output to consumed electrical energy. A high performance coefficient indicates high energy efficiency. For example, a COP of 4.0 means that 1 kW of electrical current generates 4 kW of heating output – four times the input.

• EER (Energy Efficiency Ratio): Performance coefficient for cooling operation.
• COP (Coefficient Of Performance): Performance coefficient for heating operation.

For air conditioning systems, the EER value indicates the performance coefficient during cooling, while the COP value represents the performance coefficient during heating. As these values are determined for a single operating point, additional performance coefficients have been defined specifically for air conditioning that take partial load into account, as well as climatic influences.

• SEER (Seasonal Energy Efficiency Ratio): Annual performance coefficient for cooling operation.
• Extended by seasonal factors.
• Measurement points include temperatures of +20, +25, +30, and +35°C.
• SCOP (Seasonal Coefficient Of Performance): Annual performance coefficient for heating operation.
• Extended by seasonal factors.
• Measurement points include temperatures of +12, +7, +2, and -7°C.

The annual performance coefficient for air conditioning systems and heat pumps is called SEER for cooling operation and SCOP for heating operation, and it takes into account temperature changes throughout the year.
