Abstract: In this paper, a new combined power, heating and refrigeration system is proposed, which combines the ammonia-water power/refrigeration system and steam ejector refrigeration system (SERS). This system was driven by biomass fuels and can produce both power and refrigeration simultaneously, besides according to the temperature of inlet streams into absorbers and rate of heat losses, these heat losses are used as floor heating. Moreover, high grade heat source is used in SERS; therefore, the entrainment ratio and efficiency of system are increased. The results show that the turbine inlet ammonia-water concentration, turbine outlet mass flow rate and turbine efficiency have effects on the turbine power output, refrigeration output, efficiency and exergy destruction in each component in the combined cycle.
