Résumé

Direct-expansion (DX) cooling and heat pump systems have often been the less respected alternative for building conditioning compared with hydronic systems. In general, they are considered to be a “cheaper” system, with higher maintenance cost,
shorter lifespan, limited controllability and lower energy efficiency. On the other hand, they are often more convenient, more amenable to design-build procurement, and less demanding of operator expertise.
