Comparison of Thermal Buffer Effectiveness

Test Design and Implementation: CAS DataLoggers Engineering Manager Terry Nagy together with CAS DataLoggers Product Manager Dana Kennedy

Author: CAS DataLoggers Technical Writer Stew Thompson

Abstract: Experimental data was collected to examine the behavior of RTD probes in various thermal buffers in refrigerator and freezer applications. From the warm-up time vs. temperature curves, a thermal time constant was determined by fitting an exponential line to the data. Also, the behavior of the buffers during typical operation as the refrigeration compressor cycled on and off was observed. Using this data, recommendations on buffers for refrigerators and freezers are made.
