PERFORMANCE OF RESIDENTIAL AIR-TO-AIR HEAT EXCHANGERS DURING OPERATION WITH FREEZING AND PERIODIC DEFROSTS.

Author(s) : FISK W. J.

Summary

IN A LABORATORY STUDY OF THE PERFORMANCE OF RESIDENTIAL AIR-TO-AIR HEAT EXCHANGERS DURING OPERATION WITH FREEZING AND PERIODIC DEFROSTS, FREEZING CAUSED THE TEMPERATURE EFFICIENCY OF A CROSSFLOW HEAT EXCHANGER TO DECREASE AT A RATE RANGING FROM 1.5 TO 13.2%/H AND 0.6 TO 2.0%/H WITH A COUNTERFLOW HEAT EXCHANGER. THE AMOUNT OF TIME REQUIRED TO DEFROST THE HEAT EXCHANGER'S CORE WAS 6 TO 26% OF THE TOTAL OPERATING TIME. THE RESULTS SUGGESTED THAT THE RATE OF PERFORMANCE DETERIORATIONS CAN BE REDUCED BY AVOIDING SMALL AIRFLOW PASSAGES.
