Abstract
The process of selecting a suitable heat exchanger for a drying process is proposed in this paper. In a drying process the main objective is to remove water in a way that does not cause damage to the material or environment in question. One suitable way to do this is through convection heat transfer where air is directed at a slightly elevated temperature and with low relative humidity. The air leaves at a lower temperature and with a higher relative humidity of the air. After this, this condensing water is withdrawn from the air and from the system and the dry air returns to the process. Using the EES software it was possible to model an ideal drying system. After the modeling of the process in the software, the relationship between the water condensing flow to be withdrawn in the drying system and the heat load of the heat exchangers was found. This was possible by entering different flow values and taking the thermal load values in the EES software. It was possible to note that this relationship is linear and that for a higher condensing water from the system there must be a higher thermal load on the heat exchangers. This information is of great importance in the design and selection of condensers and evaporators.
