摘　　要：Absorption chillers are cooling units usually powered by renewable energy or waste heat.Their performance generally depends on the temperatures of the heat source,the ambient and the medium to be cooled.The present work deals with the thermodynamic study of a 10 kW NH3/H2O absorption machine in order to find the COP(coefficient of performance).The first and second laws of thermodynamics were used for the operating conditions.The thermodynamic properties of the NH3/H2O mixture were determined using the EES(Engineering Equation Solver)software.The results of the simulation of the machine were validated with the results of the literature.After validation,the program was used to simulate a 10-kW NH3/H2O absorption machine for milk conservation/cold storage in northern Senegal.The simulation results of the 10-kW ammonia-water absorption machine give an acceptable COP of 0.521 with a milk storage temperature of 4°C.
