The first Law of Thermodynamics is connected to a single stage Lithium Bromide- Water Vapor Absorption Refrigeration framework and the execution examination of every part is determined through numerical model on MATLAB 7.0.1. First law of thermodynamics is additionally used to ascertain to assessment of mass flow rate and heat rate in every part of the framework. Estimated the thermodynamic properties and Energy transfer rate in every part of Vapor absorption refrigeration system, with the assistance of empirical relation. The goal of this paper is to show observational relations for finding the attributes and execution of a solitary stage Lithium bromide – water (LiBr-H 2 O) vapor absorption refrigeration system. The fundamental heat and mass exchange conditions and suitable conditions depicting the thermodynamic properties of the working fluid at all thermodynamic states are assessed Mass stream rate and heat flow rate in every segment of the framework are classified. The coefficient of performance of the system is deciding for different temperatures ranges. It very well may be seen that when the temperature of inlet water expands, the required circulation ratio diminishes, and the system COP esteem increments. In the event that the temperature is underneath 58°C, the system COP will be near zero, the system does not work by any means and from 58°C to 83°C, the COP will increment in a slower pace, after 83°C of generator 2 temperature the COP increment quickly.
