This paper writes a new simulation program for the ammonia-water absorption system using c# language in Visual Studio software. In this program, the properties of ammonia-water solution and the governing equations of each component and the whole system are solved simultaneously. As an example, an ammonia-water absorption heat pump system of 1000kW with a regenerator and an over-condenser is designed. The ammonia-water absorption program is used to simulate the steady-state operation performance of the system. It is found that the coefficient of performance (COP) of the system decreases with increasing condensation pressure and increases with increasing evaporation pressure. The calculation results of the program are consistent with the theoretical analysis which basically validates the program. This program is convenient for simulating absorption systems with varied configurations by adding new components and the corresponding equations, providing a simple and fast calculation method for the design of an ammonia-water absorption system.
