Compressor set is the main energy-consuming equipment of gas stations.Calculating the efficiency of compressor set is an important step to evaluate the energy efficiency level of gas stations and carry out energy-conservation work.The analysis and research results indicate that the existing calculation method of the efficiency of compressor set is not suitable for unstable working conditions in gas stations.On this basis,based on the energy equation of the open thermodynamic system,this paper proposes a calculation method for the efficiency of compressor set in gas stations.To improve the practicality of the algorithm,aiming at the calculation parameters that cannot be directly measured by field instruments,this study has determined the specific calculation method of such parameters,and applied these methods to the field test and calculation.The research results show that the calculation method of the efficiency of compressor set has the advantages of few required parameters,reliable calculation results,and strong operability.Related institutes can apply this calculation method to understand the actual energy level of the compressor set,thereby promoting energy saving and reducing energy consumption in gas stations.
