    The objective of this work is to analyze different approaches to performance enhancement of single effect absorption cooling machines. Techniques employed for increased performance include improvement of the solution heat exchanger, generator-absorber heat recovery, and novel fluid testing. A 2.0 KW lithium bromide absorption machine will be constructed and tested to determine the effectiveness of a solution cooled absorber. A feasibility study was performed to determine possible increases in COP. When a single effect cycle baseline case was calculated with typical operating temperatures and effectiveness, a COP of 0.79 was obtained. Methods of increasing the performance include raising heat exchanger effectiveness and employing heat recovery. By implementing those techniques, it was found that the calculated COP could be increased to a maximum of 0.87. We present in this work the calculations for the performance projection of the cycle with LiBr and water as the working fluid. The equations for heat and mass balances are included together with the assumptions adopted for circulation rates. Loads for each heat exchanger are shown for various operating conditions as a function of the low cycle concentration.
