Parametric studies on ammonia-water compression-absorption refrigeration system.
Author(s) : AGARWAL R. S., PRATIHAR A. K., KAUSHIK S. C.
Summary
Simulation of a 500 kW capacity ammonia-water compression-absorption refrigeration system has been carried out for water chilling application for summer air conditioning to study the effect of various parameters on the performance of the system. Simulation has been performed for four different configurations of system having different relative areas of the solution heat exchanger viz. 15, 21, 28 and 35%. The effect of mass flow rate of weak solution and relative solution heat exchanger area on the COP of system has been studied. The results show that the COP of the system can be increased by maintaining low mass flow rate of weak solution and increasing relative area of solution heat exchanger. Increase in the relative solution heat exchanger area from 15 to 35% resulted in an increase in COP by about 9%.
