Abstract:
Refrigeration and air conditioning systems need to have enough capacity to maintain the desired temperature at a worst-case, design load operating condition. In this paper, a dynamic analysis of a single-stage vapor-compression refrigeration system is presented. The model is constructed by applying the lumped parameter approach to each component of the refrigeration system; the first low of thermodynamic is applied to individual components to determine the mass and energy balances; then, a linear dynamical system is obtained. The model is implemented by MATLAB and simulation results are given for comparison with real values. The results of the simulation match with the manufacturer’s specifications.
