A novel kind of ammonia absorption refrigeration(AAR)system without solution pump and distillation equipment for air conditioning was presented. The basic operation property parameters were selected and a new parameter of solution reservation of generator

β was defined for the special system. Then the thermodynamic characteristics were analyzed by means of boiling temperature

condensation temperature

and water content in refrigerant as well as solution reservation of generator. The results show that coefficient of performance could be up to 0.28 when calculated cooling capacity is set at 1.5 kW

which indicates that the system is feasible in using waste heat and solar energy. When β increases from 0 to 3

the decrease of coefficient of performance would be up to 60%. Water content deteriorates cooling capacity and coefficient of performance significantly

the system could lose cooling capability when the water content is greater then 0.14. Both increasing boiling temperature and reducing condensation temperature could enhance the coefficient of performance. The solution to reducing the influences of these parameters was also discussed.
