A mathematical model describing the transient behavior of condensers in a small compressor refrigeration capacity test system is presented. This model uses the thermodynamic views and methods based on the conservation of energy, mass and momentum and consists of seven dynamic differential equations with distributed parameters. The model is the basis for optimizing the design of the test system condenser and the control strategy for testing the test conditions. Experiments show that the model and experimental results have consistent trends.
