A HEAT TRANSFER SYSTEM

摘要

An access floor system comprises a plurality of floor panels 1 and associated support pedestals 2. The floor panel 1 comprises a base and a top 11. A plurality of integral strengthening projections 15 extend from the base 10 towards the top 11. The projections 15 are welded to the steel top 11. The panel has an inlet valve 18 and an outlet valve 19 which are connected to water flow and return lines so that hot water is circulated through the hollow space 12 defined between the base 10 and top 11 from the inlet 18 to the outlet 19. In one arrangement a heat reflector such as a layer 20 of a suitable heat reflecting means is applied over the face of the base 10 to reflect back heat and hence minimise heat dissipation from the underside of the panel. In another arrangement a heat conducting means 25 of a suitable material such as ceramic is applied to the upper surface of the panel to act as a heat sink to store heat and assist in heat transfer to the room space. The panel may be inverted so that a dimpled side 30 is uppermost for enhanced heat transfer to the room space.
