This group contains one or more emissive devices. These emissive devices are subsequently coupled to a distribution network, which in turn is linked to a generation resource (depending on the module).
A local heating-/emissive device, or an air handling unit with a heating coil (air heating) should be defined in a heated room for the heat loss calculations. No emissive devices for heating, and no air handling unit with heating coil are allowed to be specified in an unheated room.
CL
Instead of defining emissive
devices, it suffices to specify whether cooling is present in the room for the
cooling load calculations. The calculation method for cooling load is based on
systems in which the cooling load is absorbed by the supplied air
completely.
