Modular construction of LAUDA Heating- and Cooling systems -
Modular documentation
Heat transfer takes place at different locations within a single fluid heat transfer system. Whenever the heat transfer medium flows around vessels, exchangers or other interface surfaces that are colder or warmer than the medium, then thermal energy endeavours to be transferred from higher to lower temperatures. It is the temperature difference and size of the exchange surface area that are decisive variables in single fluid heat transfer systems.
Other important influences are flow velocity that creates turbulence and good mixing capabilities within the vessel or heat exchangers, as well as the thermodynamic properties like density, thermal conductivity, specific heat capacity, and viscosity. Fouling, surface areas and materials used also have an important influence on heat transfer. Once these factors are all known then the technical specifications of the apparatus can be calculated with heating or cooling performance being simulated by hand or even better by computer program. Accurate simulation of the process makes it possible to find the optimum solution from the LAUDA modular system at the very beginning of a project.
