Abstract The paper describes a FORTRAN computer program, ISTORE, designed to simulate the optimum operation of an ice‐storage air‐conditioning system under a time‐of‐use electricity tariff. The model uses capital cost and operating cost data to optimise the sizes of the component chiller set and store for an annual operating cycle which can take into account several different seasonal load conditions. Where applicable, the model can also optimise settings for maximum electricity demand. The model provides comprehensive graphical and printed output which allows optimum control strategies to be quickly identified. An example study is given which indicates that considerable savings are available under a maximum demand tariff by using the ice‐storage technology as a load management device to reduce air‐conditioning costs.
