Functions determining on absorption refrigeration systems (IFA) with value engineering analysis method (AIV)

Abstract

Because in the analysis and value engineering (AIV), a product is considered as a sum of functions and not components, this is true also for absorption refrigeration system (IFA) within air-conditioning installation. It is very important to set correctly all these functions because the omission or incorrect classification of some of them, would lead to inaccurate assessments. The role of refrigeration systems should not be confused with their functions because the expression is general and encompasses many distinct functions, functions that must satisfy the requirements of users.
