This Annex was directed at widening the use of compact heat exchangers (CHEs) in heat pumping systems. The Annex wanted to show that these can improve efficiencies, minimise fluid inventories and reduce package size. The annex collected data during to quantify the possible benefits from CHE use, and also highlight any concerns. 

Objectives

The objective of this Annex was to present a compilation of possible options for compact heat exchangers, used as evaporators, condensers and in other roles in heat pumping equipment. The aim was to minimise the direct and indirect effect on the local and global environment due to operation of, and ultimate disposal of, the equipment.
