Abstract


With the arrival of the energy source crisis worldwide,governments in many countries have been promoting the energy saving techniques actively.Inverter air conditioner has gradually become the central direction of development of air-conditioning manufacturers because of high-performance,energy saving characteristics.The fuzzy-countrol technology is more and more valuable for each factory.The contents of the article comes from Inverter air conditioner electrical part which are being researched of Domestic company.This paper mainly design electrical part of the inverter air conditioner indoor and outdoor On the hardware side.And completed the relevant software design and selection of chip. In order to the air-conditioning unit control system which works in the outdoor environment structure Simple, high efficiency and high reliability,outdoor electrical part choose intelligent power module and microcontroller to build the entire system,In the system,IPM works as the inverter.Indoor mainly made up of indoor fan control,temperature sampling,and the communication circuit of Indoor and outdoor.The compressor of inverter air conditioner is a core part of the whole system,the running performance of compressor will directly affect the performance of the entire air-conditioning system.Therefore,need high-performance control for compressor runing, based on the parameters of compressors and requirement of control to complete the design of compressor frequency control system.As MN103SFC2DXW type of Panasonic as the core controller,optimize main circuit,control circuit,protection circuits and communications circuits,and gives the inside and outside software design flow chart.The fuzzy control applied to inverter air conditioners,made compressor avoid frequent starts,low noise at work,high precision temperature control.Be able to create a more comfortable environment of room temperature controlled.Finally,make a system debug for the entire air-conditioning system,Shows the test waveform,and make a analyse of waveforms,demonstrated the feasibility of the whole system.
