Steady State Model of Screw Chillers Suitable for Variable Conditions Simulation

Abstract:

To predict the performance of screw chillers in variable operating conditions, a steady state model of screw chillers suitable for variable conditions simulation was built and tested. Comparison between the predicted value and the experimental value shows good agreement. The results show that this model is suitable for variable inlet temperature and mass flow rate of chilling water and condensing water. Refrigerating capacity and condensing heat release condition of a specified screw chiller could be calculated if a set of outer thermal parameters is gained. This model is useful for simplifying performance test, equipment selection and running control.
