초록정보

The absorption refrigeration system is one of the alternative for use with solar and the other sources of thermal input such as geothermal and waste heat. The absorption refrigeration system, using LiBr $H_2O$ as a working fluid, consists of a generator , an evaporator , an absorber , a condenser , and a solution heat excharger. These components have an organic relations with each other. The coefficient of performance of this system depends on the temperature of the generator, the temperature of the cooling water and the flow rate of the solution, etc. Generally, in design of an absorption refrigeration system and optimization of the coefficient of performance (C.O.P), the most important variable which has to be taken into account is the temperature of the generator because the other parameters of the system depend on the initial conditions and consequently and fixed. The experimental study was performed with two selected variable, the temperature of the generator and the temperature of the cooling water. In order to determine the temperature of the generator which gives maximum. C.O.P, the experimental data have been obtained with controlling the temperature of the generator in the range 20-32℃ of the temperature of the cooling water. The range of the generator heat suppling temperature which gives maximum is about 90-95℃. This temperature range depends on the characteristics of the equipment unit. The most important result in this experiment is the trend of the C.O.P in according to the variation of these temperature. From the analysis of the experimental result, it is found that the lower the temperature of the cooling water is, the higher the C.O.P of the system is, and the higher the temperature of the cooling water, the higher the temperature of the generator at the best condition. The major objectives of this thesis is to furnish informations and knowledges for designing and operating absorption refrigerator.
