An extensive review of the literature was conducted which was concerned with the characterization of systems and equipment that could be applicable to the development of solar-powered air conditioners based on the Rankine cycle approach, and the establishment of baseline data defining the performance, physical characteristics, and cost of systems using the ...
An ammonia--water absorption air conditioning system has been tested to investigate the stability of operation near the cut-off conditions. Circulation ratios were from 8 to 30. Relations for the estimation of the coefficient of performance and for the prediction of operating temperatures were derived and verified experimentally. Possible operating ...
