Definition of the process for the calculation of heat exchangers<\/h2>\n

 <\/p>\n

A\u00a0heat exchanger<\/strong><\/span><\/a> is an energy exchange system\u00a0(in the form of heat) between a hot and a cold fluid. In practice, all the thermal duty<\/strong> of the hot fluid (fc) is transferred to the cold fluid (ff), thereby fulfilling the next\u00a0energy balance<\/strong>:<\/p>\n

 <\/p>\n

\"Energy<\/p>\n

 <\/p>\n

The\u00a0thermal duty<\/strong>\u00a0of a fluid in liquid state\u00a0depends on the mass flowrate<\/strong>\u00a0and\u00a0the temperature differential between the inlet and outlet sections<\/strong>. In a fluid with a change of phase in saturated conditions (either condensation or evaporation), the heat power depends on the mass flowrate and the enthalpy of the phase change, that is determined by the saturation pressure.<\/p>\n

 <\/p>\n

The process is defined when all the features have been fixed by the client, except of one, that will be calculated by means of the above-mentioned thermal balance<\/strong>. As an example:<\/p>\n
