An alogirthm for the computer simulation of a solid absorption soalr refrigerator, COSSOR, is presented. The algorithm is based on a detailed transient mathematical model of the system. It is a sequential modular program which consists of a relatively short main program and about 50 subprogrmas which are called by name by the main program or other subprograms. The program is coded in QBASIC, is highly flecxible, accurate and fast, and has been tested on a wide variety of personal computers. Predictions of the refrigerator performance obtained using COSSOR compare very well with experimental data over a wide range of operating ocnditions. It is therefore a useful tool for computer aided design, performance prediction and analysis of therefrigerator, and may find applications in other solar thermal systems. Typical predicted results for some stations are given.
