MAINTENANCE AND RELIABILITY OF INDUSTRIAL REFRIGERATION SYSTEMS

Abstract

The objective of this paper is emphasizing the importance of maintaining the cooling systems from the perspective of exploitation safety. The comparative analysis of the natural and synthetic refrigerants is made. An overview of the location of possible operation problems is given. There are cited the most common mistakes of industrial cooling installations that hinder maintenance and lead to incidents followed by leaking in the exploitation conditions. The accent is put on parts of refrigeration installations at high pressure in specific periods of operating (evaporator defrosting). Special attention should be paid on monitoring of leaking in liquid lines (especially with over-flooded systems). Finally, the routes and suggestions for better maintenance and safety improvements are given.
