Modular room heat exchange system with light unit

A modular heat exchange system for use in central heat exchange installations in buildings, comprising

• at least one heat exchange element equipped for exchanging heat between environmental air and a fluid which is conducted through the heat exchange element, said heat exchange element having a predetermined first shape with opposite lateral sides,
• at least one non-heat-exchange add-on element, equipped for adding a given additional functionality to the system, having a predetermined second shape with a complementary lateral side to one of the opposite lateral sides of the heat exchange element, such that when the heat exchange element and the add-on element are fixed adjacent each other with one of said opposite lateral sides and said complementary side facing each other, the first shape of the heat exchange element continues into the second shape of the add-on element;
• said heat exchange element includes a technical part for conducting said fluid, said technical part comprising a front member of a non-heat conductive material, a back member of a heat conductive material and a sealing in between the front and back members for making the technical part substantially fluid-tight;
• said back member comprises a flat base having one side for contacting said fluid and an opposite side provided with a plurality of upstanding fins spaced at regular distances from each other for exchanging heat with said air;
• a wall mount which is adapted for being fixed to a wall and for holding said technical part, said wall mount being constructed in a non-heat conductive material and comprising a layer of soft material for engaging the upstanding fins of the technical part;
• and
• wherein one of said at least one non-heat-exchange add-on elements comprises a light unit.
