SIMULATION THE FOOD COLD STORAGE USING A BOND GRAPH MODEL LIBRARY IMPLEMENTED IN SIMSCAPE

Abstract

Refrigeration system is widely used in multi domain under different scales. For household and industrial system, the typical application of refrigeration system is food preservation. In order to optimize system performance, it is necessary to compute and analyze exactly the time – variance of state variable of elements. Using pseudo – BondGraph language, the operation of refrigeration system for food preservation is simulated via Simscape toolbox of Matlab & Simulink. The variation due to time of operational point of each element is described continously in logp-i diagram which is very acquainted with thermal engineers.
