Please refer to .

Any thermal machine can only function if it is placed between a source of high thermal potential (hot source) and a source of low potential (cold source). This section provides an overview of the different types of cold sources found on power generation sites, or even on industrial sites when a cooling function is required. This function requires condensation exchange, as the fluid coming from the turbine is nothing other than wet steam, which has to be condensed. However, this type of installation is always associated with a condensing turbine. The cold source is a particularly important point of power exchange, since in this case between...
