The invention relates to a hydrogenation precooling control method and system for a hydrogenation station, and belongs to the field of new energy. Wherein the control method includes the following steps: 1) obtaining the initial temperature data and initial pressure data of the hydrogen storage bottle; 2) according to the initial temperature data and initial pressure data, and the set hydrogenation amount, calculate the mode of the set rate The calorific value Q 1 generated and the calorific value Q 2 generated when the hydrogenation reaches the set temperature upper limit T 0 ; compare the magnitudes of Q 1 and Q 2 , when Q 1 <Q 2 , the refrigeration unit will not be started; Q 1 >Q 2 o'clock, start the refrigeration unit. The opening and closing state of the refrigeration unit of the invention can be adjusted according to the temperature and pressure of the hydrogen storage bottle, thereby avoiding the waste of energy consumption caused by blindly setting the refrigeration unit to a constant lower pre-cooling temperature, and facilitating the The control of the hydrogenation rate is beneficial to improve the hydrogenation rate, and achieves both the hydrogenation rate and the energy consumption. |
