In heat exchangers, thermal energy is transferred from one mass flow to another. The two mass flows do not come into contact with each other in this process. To avoid losses, efficient heat transfer must be ensured. For this reason, different types of heat exchangers are used in practice, depending on the requirements. The WL 315C trainer allows students to examine and compare five different types of heat exchangers. Heat is transferred in the heat exchangers according to the principle of countercurrent or parallel flow with different fluids. The heat exchanger to be examined is selected in the switch cabinet. Valves are used to switch between parallel flow and counter flow. The flow rate in the hot and/or cold water circuit is also adjusted through valves. Hot water flows through the heat exchanger and transfers some of its thermal energy to cold water in this process.
