System for testing energy efficiency of vortex tube heating natural gas

The invention provides a system for testing the energy efficiency of vortex tube natural gas, and belongs to the technical field of pipeline systems. The system for testing the energy efficiency of the vortex tube heating natural gas comprises a pressure adjusting unit, a data acquisition unit and a gas source, the pressure adjusting unit comprises a gas supercharger and a first pilot pressure reducing valve, and the gas source is communicated with a vortex inlet of a vortex tube heater to be detected. The inlet of the gas supercharger is communicated with the vortex outlet of the vortex tube heater, the gas source is communicated with the first pilot inlet of the vortex tube heater, and the data acquisition unit comprises a first pressure sensor, a second pressure sensor, a first temperature sensor and a second temperature sensor. Different working conditions are simulated through the pressure adjusting unit, the energy efficiency of the vortex tube heater for heating natural gas is accurately tested through
