LoginThe faults during design and installation phases are more critical with cooling systems than with normal HY AC systems: direct evaporated systems in particular require experienced engineers and mechanics. The most common fault is oversizing the systems and the design of the year-round-use system without winter conditions equipment. When the outdoor temperature is cold these systems present problems. The aim of this paper is to present the retrofitting concepts of cooling systems together with improved energy efficiency and operation of the system. This paper considers DX cooling systems, water chillers and room- air conditioner packages. The reasons for the typical faults in the cooling systems are analysed and examples retrofitting the systems are presented. Also some practical points for the design of these cooling systems are presented. The dimensioning of the whole system is specially given attention.
