Summary

Heat exchange is, with compression, the other essential component of a refrigerating circuit. More so as there are generally at least two exchanges per installation, and still more so in the case of an indirect circuit. And, in this field also, evolution is still possible. The technical Centre of Aeraulic and Thermal Industries (Cetiat) reveals some results of its work on these famous aluminium components. To go further, the laboratory chose to study the operation of these microchannel exchangers with a refrigerant with a future: R410A, a fluid made up of a mixture of three other HFCs, considered as being a fluid without temperature glide. Technologies are thus evolving. However, this does not exempt us from returning to heat exchange basics and benefiting once again from the expertise of George Rigot to review heat exchange basics, appealing to "the refrigeration technician's experience, expertise and common sense" to place in perspective certain information sometimes provided by manufacturers in terms of performance.
