The module provides the possibility of designing cooling system (it is equivalent to the ‘Heating systems’ module). It supports various types of convection receivers (fan-coils, passive refrigeration beams) simulated by a common ‘Receptor’ with imposed resistance. Together with the ‘Radiant systems’ module, the following radiant systems can be designed: floors, walls, ceilings. In combination with the ‘Radiant panels’ module, panel systems can be designed in cooling mode. In both cases, cooling calculations can be made regardless of the heating mode. In projects with a common source for convective and radiant systems, it is possible to use mixers or pump-mixing sets to obtain temperatures appropriate for radiant systems.
