To find out the thermodynamic characteristics of an air scroll compressor with asyn-chronous discharge of symmetric chambers ,thermodynamic calculation was combined with geometry characteristics .For avoiding the amplification of calculation errors when the discharge volume was ti-ny ,the thermodynamic process was divided into two stages :the air pressure in two discharge chamber equal or not .The calculation methods of the corresponding mass and discharge temperature were es-tablished ,the calculation results have a good agreement with the experimental results .The curve of pressure and temperature was analyzed in a compression run .
