Abstract
- Summary: The ionic liquid compressor is regarded as the most promising compression technology for the hydrogen refuelling station due to the combined application of ionic liquid and the hydraulic driving system. However, the design, mathematical and experimental investigations of the ionic compressor are still absent from the open literature. This paper proposed a new structure design and the design methodology of the ionic liquid compressor. The mathematical modelling considering the valve dynamics was provided for simulating the thermodynamic process, which was verified by the experimental data. The results showed that the delayed closing of the discharge valve would take place due to a high or low stiffness of the valve. The increase in the stiffness alleviated the rebound issue of the suction valve. An increase in the stroke to diameter ratio could solve the rebound issue of the discharge valve. A low or high trajectory coefficient would cause an intense rebound during the closing procedure of the discharge valve. The designed results of the main parameters of the compressor based on the simulation were the suction valve stiffness of 100 N/m, the discharge valve stiffness of 500 N/m, the stroke to diameter ratio of 1.0, and the trajectory coefficient of 0.125 under the given design condition.
