A new generation of ammonia unit coolers.

Nueva generación de refrigeradores de unidades de amoníaco.

Type of article: Article


This article is the Spanish translation of an article presented at the IIR conference in Ohrid, Macedonia (see the Bulletin of the IIR, reference 2009-1504). The industrial series of ammonia unit coolers is the result of lengthy and intense research, both theoretical and - to a greater and more important extent - experimental, principally aimed at defining the optimum characteristics of the combination of heat exchanger coil and fan group. This document proposes to illustrate the research guidelines and to present the results obtained. Exchanger performance in the dry state is dealt with, as are the changes to the thermodynamic and aerodynamic behaviour of the equipment generated by frost formation on the heat exchange surfaces, highlighting the contribution of computational fluid dynamics.
