Chemical and Petroleum Engineering Aims and scope

In this work, the results of heat-engineering tests of refrigerating machines are compared with the results obtained by using a mathematical model. The verification is done in two ways: by using the experimentally derived characteristics of a water-cooling refrigerating machine and comparing them with the characteristics of the built and tested systems. The mathematical model is built by applying the principles elucidated in [3, 4]. The divergence of the experimental values from the calculated (theoretical) in all numerical studies made was not greater than 10%. Satisfactory convergence of the calculated and experimental data is corroborated both at the components level and at the systems level. The program package developed making use of this model helped solve a host of practical problems associated with building of energy-efficient refrigerating machines.
