“…For the lithium-iodide ternary system, the coefficient of performance values obtained were comparable with values for lithium-bromide/water systems (Eisa et al, 1986). The advantage of a higher solubility should be analysed in more detail in order to fix the limiting values of the generator temperature.…”

An alternative to the use of the traditional lithium‐bromide/water system for absorption cooling is discussed. An experimental study is presented on the use of salt mixtures of lithium‐bromide/zinc‐bromide and lithium‐bromide/lithium‐iodide as absorbents for water. It is shown that the higher solubilities of the ternary systems allows operation at higher absorber and generator temperatures without the risk of crystallization and with low enough evaporator temperatures for practical cooling applications.

The objective of this research paper is to present steady state simulation model and EES program for design and thermodynamic analysis is used to predict the performance of single effect vapor absorption chiller. The working condition of steam is entering and exit to the generator. At that point, the program gives the thermodynamic properties of all purposes of the state, for example, design information each heat exchangers in the cycle and the overall performance of the cycle. The outcome is from EES program is utilized to contemplate the impact of structure parameters on cycle performance. In the conventional absorption refrigeration system dilute solution of LiBr is directly goes to the generator at inlet of generator in this type high heat source is required and increasing the area of the generator. In this paper is to present incorporation of heat reclaimer in the solution heat exchanger and the generator. The addition of one heat exchanger with increasing COP as well as reduced heat source and heat transfer area in the generator. This program gives the operating parameter at all state points, design value of all heat exchanger and design performance of the system. The refrigeration capacity of the system is 100TR. To check the performance of system by using changing flow rate of heat source, heat exchanger effectiveness. The output of this program and simulation results use for the sizing of new refrigeration system.

The objective of this paper is to develop a computer program for design and thermodynamic analysis of a single effect absorption chiller using LiBr-H2O solution as working fluid. The conditions of hot water entering and leaving the desorber, cooling water entering the absorber and leaving the condenser, chilled water entering and leaving the evaporator, as well as the approach temperatures in condenser, evaporator, desorber, and absorber, the effectiveness of solution heat exchanger, the chiller refrigeration power, and the ambient temperature are used as input data. The program then gives the thermodynamic properties of all state points, the design information of all heat exchangers in the cycle and the overall cycle performance. The results deduced from the computer program are used to study the effect of design parameters on cycle performance. For example, increasing the evaporator and generator temperatures or decreasing the condenser and desorber temperatures can improve the second-law efficiency of the cycle. It is also noticed that the temperatures of hot water, cooling water, and chilled water, respectively, at the inlet of the desorber, condenser, and evaporator have a great effect on cycle coefficient of performance. The results of this program can be used either for sizing a new refrigeration cycle or rating an existing system. It can also be used for optimization purposes. The predictions of the present program are compared with other simulating programs and qualitative agreement is achieved.
