| Abstract: | The calculation of thermodynamic cycle parameters is mainly introduced in the paper when the frequency is converted.The aim is to find the laws of the thermodynamic parameters' change under certain evaporating temperature and vario us environment temperature and rotating velocity of the compressor.The parameter s include pressure,temperature,refrigerating effect,power and so on.It is helpfu l to the understanding of the model of the controlled plant when a control syste m is established. |
