• 英文摘要： With the available commercial software (ChemCAD version- 3.30), the computer simulation of an ammonia-water absorption cycle for refrigeration has been carried out in the present paper. It is found that, because of the capability of reducing the water contents in the vapor phase of ammonia refrigerant, the distillation tower can successfully replace the generator and consequently increases the COP of the cycle. An illustrative study is given on a general equilibrium stage tower with a partial condenser. From the simulation results, it is found that this equilibrium stage tower can provide a good separation effect for those water contents in the vapor phase of refrigerant, and therefore can increase the COP of the cycle efficiently.
