Eliminating internal haemorrhage in hot gas defrost systems.

Number: 1136

Author(s) : PEARSON A.

Summary

The most common method of defrosting ammonia evaporators in large cold store or freezer systems uses hot gas. There are several methods of achieving an effective defrost but they can cause a significant penalty in system capacity and operating cost if they are not maintained in good condition. This paper describes the options for hot gas defrost and outlines the steps required to maintain good performance, with the consequences of failure to do so. Design guidance to eliminate the problems for the construction of new systems is provided and maintenance checks are described.
