Résumé

This paper describes work in progress of a mathematical model aimed at simulating the steady state performance of an indirect refrigeration cycle as part of a multi-temperature transport refrigeration system. Use of indirect or secondary refrigerants represent an alternative design approach to direct expansion systems and may offer certain operational advantages over existing systems. The overall purpose of the simulation model is to serve as a design and evaluation tool for secondary refrigeration systems thereby enabling the performance of such systems to be examined and optimised. In this work, the model has been created using the Engineering Equation Solver and utilises an iterative approach by which the overall governing equations are solved. Empirical correlations are used to calculate appropriate heat exchanger convection and pressure drop coefficients. An empirical regression model is utilised to model the system compressor.
