Seg control circuit principle

Seg also USES frequency conversion air conditioning haier 98 c029 special large scale integrated circuit, the small diesel generator chip temperature collection, over- current, overheating, prevent the protection function such as frozen, can also be 30 ~ 125 hz PWM output pulse signal, drive the compressor, the air conditioner from one to three horses. Emergency turns, fixed fan cover output of 60 hz frequency operation, then can carry out measuring pressure, current and so on maintenance work. Transmitted from the cPu receives outdoor indoor machine (cooling, heating, wet, compressor operation frequency) control signal, such as outdoor fan control, four-way valve, and through the inverter control imposed on the compressor motor ac motor frequency and voltage, and transform the running speed of the compressor. At the same time also will feedback the information about the operation of outdoor www.facebook.com/guohong.trading to indoor machine.
