Toshiba outdoor units are smaller and lighter
Toshiba Air Conditioning’s Series 4 outdoor condensing units are around 11% lighter (up to 8 kg) than previous models and up to 10% more efficient. For example, the SEER for the 2 hp unit has been raised from 5.89 to 6.14. The lighter weight enables units to be stacked two high to save space.
Much of the reduction in weight is due to the development of a twin rotary DC compressor, which is also more powerful than the unit it replaces.
Night set-back operation can reduce power consumption by up to 50% in 1% steps and decrease noise by up to 10 dB(A).
