Technology and fundamentals of an air conditioning system

Two drive modes – the hybrid inverter

Air conditioning systems essentially work according to the principle of heat transmission. They draw in warm air from the room, cool it down, and guide the cooled air back into the room. This is carried out using a closed refrigerant circuit (often a gas) and various components.

What makes up an air conditioning system?

Quiet and stable operation

The TOSHIBA twin-rotary compressor, which was developed and produced in-house, essentially consists of two disks rotating in opposite directions. This maximizes mechanical stability, optimizes synchronization, and thus minimizes vibrations. In short, TOSHIBA units are quiet and durable.

Stable temperature

Did you know that an air conditioning system only needs full power for approx. 15% of its operating time? The TOSHIBA inverter system with its intelligent control constantly regulates the modulation width between 20% and 100%. This creates a stable temperature without constant switching on and off.

Saving operating costs

Since the system works in "part load operation" for 85% of the time, efficiency in this range is crucial. TOSHIBA units deliver their best values in that range. This is energy efficient, easy on the wallet, and guarantees a long service life.

Two drive modes – the hybrid inverter

TOSHIBA combines the two principles of pulse height modulation and pulse width modulation (PAM and PWM for short) to drive the compressor. The hybrid inverter control therefore responds to the two demand profiles an air conditioning system has. If the desired temperature value is far away and needs to be reached quickly, PAM mode is activated – "High Power" is required here. Once the value is reached, it is maintained with the lowest possible energy consumption (PWM mode).

Air conditioners with inverter technologies operate on demand: In the case of inverter air conditioning systems, the rotational speed of the compressor is adapted to the load conditions actually required. When an air conditioner is switched on, the power required is initially very high in order to reach the set temperature as quickly as possible. However, the desired temperature can be maintained with less power after this. The inverter then automatically reduces the rotational speed of the compressor.

Energy savings

The unit automatically switches between high power and energy-saving mode with the hybrid control system, meaning the lowest electricity consumption is ensured.

Unique comfort

The unit runs extremely quietly, meaning it will not disturb your day-to-day life or sleep.

Maximum energy efficiency

The unit is highly efficient, particularly in part load operation. Since all units both cool and heat, they can be used throughout the year. At least energy efficiency class A is achieved in both functions.
