Abstract

Fundamental experiments with single row heat exchanger were conducted for the purpose of validating new defrosting method using jet impingement. The coolant temperature were varied from 83 to 250 K. We used the jet periodically, once in 50 second and the duration of the jet is 0.1 second. The effect of the coolant temperature in the effectiveness of the jet defrosting was investigated.
