التغييرات الأدائية لوحدة تكييف هواء شباكية معالحة كيميائيا للعمل في بيئة صناعية بتروكيميائية

الملخص EN

Since most of our industrial applications suffer from aging of units.

and hence the penalty of gaseous harmful releases with bad corrosive influences on airconditioning components.

However all the available solutions to diminish these influences are related to painting parts of the air-conditioning system with different substances and methods.

The present study investigates the effect of chemical painting on the performance of these air-conditioning units.

This research is a practical study which explores the influence of a specified kind of chemical painting used to paint Aluminum fins and copper pipes in the refrigeration system for window type air-conditioning units of (2tons capacity-reciprocating compressor -R-22) on it’s performance through calculating each of the capacity of refrigeration, compressor work, transmitted heat and coefficient of performance before and after the chemical painting process, and making comparison between the two in various operating conditions.

It was found that the coating causes a decrease of the capacity of refrigeration, compressor work, transmitted heat and coefficient of performance.

However it saves all parts in refrigeration system from corrosion for along time.

The practical part were conducted in the state company for electrical industries.
