States there is a lack of practical correlations for the outside heat transfer coefficient that could be used by practising engineers to design a subcooler or intercooler coil. Presents simple correlations for the shell-side heat transfer coefficient with R22 and ammonia.KEYWORDS: Heat flow, refrigerants, ammonia, R22, designing, refrigeration, intercoolers, subcooling.
