DC Hybrid Inverter System
Conventional fixed speed compressors only operate in two states: off and on (at maximum speed). Switching between these two states is called “cycling”. Incerter technology allows the compressor to operate at variable speeds rather than cycling. This means cooling hot room takes less time and less energy is consumed when the set temperature is reached.
As the inventor of the invertor, Toshiba takes this technology one step further with the DC Hybrid Inverter System. Pulse Amplitude Modulation (PAM) sets the compressor at maximum power, spinning the compressor at above the rated capacity in order to reduce the time to reach the set point temperature. Once the set point is reached, Pulse Width Modulation (PWM) controls the compressor rotation at a lower variable speed without cycling to precisely maintain room temperature, thereby using less energy.
