[In Dutch. / En néerlandais.]

Author(s) : WARDENAAR N.

Type of article: Article

Summary

THE ADVANTAGES, APPLICATIONS, DESIGN AND LAYOUT OF ELECTRIC DEFROSTING IN AIR COOLERS ARE DISCUSSED. THE DEFROSTING EFFICIENCY IS DEFINED AND RELATED TO THE EFFECTIVE COOLING CAPACITY OF AN AIR COOLER. EXPERIMENTAL RESULTS SHOW THE DIFFERENT TEMPERATURES OF THE COOLER SURFACE DURING DEFROST THE EFFECT OF SPECIFIC ELECTRIC DEFROSTING LOAD ON DEFROSTING TIME AND DEFROSTING EFFICIENCY HAS BEEN EXPERIMENTALLY DETERMINED. THE EFFECT OF THE LENGTH OF THE COOLING PERIOD ON THE EFFECTIVE COOLING CAPACITY IS SHOWN FOR 2 DIFFERENT ROOM TEMPERATURES: 273 AND 255 K (0 AND -18 DEG C). FINALLY, THE OPTIMUM DEFROSTING FREQUENCY IS DETERMINED FOR A CASE STUDY.
