EXERGY CONSERVATION IN PARALLEL THERMAL INSULATION SYSTEMS.

Author(s) : SCHULTZ W., BEJAN A.

Type of article: Article

Summary

THIS PAPER IS A SECOND-LAW STUDY OF THERMAL INSULATION SYSTEMS CONSISTING OF TWO 1-DIMENSIONAL INSULATIONS IN PARALLEL. THE PARALLEL-INSULATION MODEL APPLIES TO POWER AND REFRIGERATION SYSTEMS EXPOSED TO LARGE ABSOLUTE TEMPERATURE RATIOS. THE INSULATION DESIGN WHICH CONSERVES MAXIMUM EXERGY IS DETERMINED FOR TWO PARALLEL INSULATIONS COOLED CONTINUOUSLY BY TWO STREAMS OR COOLED PARTLY (INTERMITTENTLY) BY ONE STREAM OF SINGLE-PHASE FLUID. IN CONTRADICTION TO PREVIOUS RESULTS, THE CONTINUOUS-COOLING METHOD IS THERMODYNAMICALLY SUPERIOR TO THE PARTIAL-COOLING METHOD.
