Description

There are many buildings where heating is supplied from hot water systems under the floor. Such hot water systems are often referred to as trench heating systems. These comprise a run of two or more pipes containing hot water encased on three sides by a steel box faced on the upper surface with a grill. There is often a problem in providing an access floor that must fit between the heating base and the curtain wall, often with only a small gap to fill. This is difficult to achieve in a manner in which the access floor panels are adequately supported. Additionally known heated trench systems often form traps for debris and dust resulting in a relatively unhygienic system.
There is therefore a need for an improved heat transfer system which will address at least some of these issues.
Statements of invention According to the invention there is provided a floor panel comprising a top and a base which define therebetween a sealed hollow space for direct flow’ of a heat exchange medium through the hollow’ space, the panel having an inlet connection and an outlet connection for circulation of a heat exchange medium through the hollow space.
In one embodiment the inlet and/or an outlet connection means comprises a valve. The valve may be a self sealing valve.
In one embodiment a heat reflecting means is applied to the base of the panel.
In another embodiment a heat conducting means is applied to the top of the panel.
The heat conducting means may comprise a heat sink material such as a ceramic. -2In one embodiment the base and/or the top comprise a plurality of integral strengthening projections. In one ease the strengthening projections extend from one of the base and top towards the other of the base and top. l'he projection may be fixed to the other ofthe base and top.
In one embodiment the top and base are of steel and the projections extend from one of the base and top and are welded to the other of the base and top. A vent hole may be provided through the projection.
The invention also provides a heat transfer system comprising a plurality of floor panels of the invention.
The system may comprise support pedestals for the floor panels. At least some of the support pedestals may have an integral connection means for a heat exchange medium.
The system in one embodiment comprises pipework for circulating a heat exchange medium through the floor panels. The heat exchange medium may be a heating fluid or a cooling fluid.
Brief Description of the Drawings l'he invention will be more clearly understood from the following description thereof given by way of example only with reference to the accompanying drawings, in which :Fig. 1 is a perspective view of a floor panel system of the invention; Fig. 2 is a perspective view of the underside of portion of a floor panel system of the invention; IE 0 80851 -3Fig. 3 is a cross sectional view of the floor panel; Fig. 4 is a plan view in the direction of the arrow A in Fig. 3; Fig. 5 is an enlarged view of the panel, in use; Fig. 6 is a view similar to Fig. 5 illustrating a modified panel: Fig. 7 is an exploded cross sectional view' of a modified panel assembly; Fig. 8 is a cross sectional view of the panel assembly of Fig. 7; Fig. 9 is a cross sectional view' of another panel assembly of the invention; and Fig. 10 is a perspective view of portion of another floor panel system of the invention with pedestals having a built-in valve.
Detailed Description '1 his invention provides an access flooring system of the type comprising a plurality of floor panels 1 and a plurality of support pedestals 2 for supporting the floor panels 1. fhe pedestals are distributed over a subfloor, and the pedestals are arranged to support the floor panels such that floor panels may be individually removed to gain access to the chamber below the floor panels. When assembled, the floor panels provide a relatively flat and strong floor to support office personnel, furniture and the like.
In the invention we provide a hollow floor panel 1 sealed such as to be able to contain water, or other suitable heat exchanger fluid, fhe floor panel can be any size to suit the floor grid to be installed. A typical size may be 500mm or 600mm square with a thickness of about 30mm.
IE 0 80 851 -4Water can be supplied from pipes 3 installed under the access floor and connected with flexible hoses to the hollow floor panels. The connections 4 can be of several forms from a simple screw assembly to a more complex self sealing valve, fhe self sealing valve permits removal of the heated floor panel from the water system without recourse to draining the system and with minimum water spillage. An adjustable restrictor accessible from the top to adjust the water flow and hence heat output may be incorporated into the floor panel.
Connection valves 5 may be free standing as illustrated in Fig. 10 allowing a high degree of system flexibility as the panels 1 can be easily moved around a floor to optimise heating for a given area.
Alternatively the valves may be combined with support pedestals such that a panel may be removed and installed simply and the fluid connection broken/made as the panel is moved. However, this may be less flexible since the pedestals may have to be specific for the heated panels. However, the same pedestals could be used throughout a floor.
Referring to Figs. 3 to 6 in this case the floor panel 1 comprises a base 10 of an egg crate" form and a generally flat top 11. The base 10 and top 11 are preferable of a heat conducting metal such as steel. The bases 10 and tops 11 are welded together to form a sealed hollow space 12 for circulating a heat exchange medium. A plurality of integral strengthening projections 15 extend from the base 10 towards the top 11. The projections 15 are in this case of generally dome-shape and are welded to the steel top 11. The weld could be of a circular form the centre of which may be punched out to enhance air flow. Air flow could be further enhanced locally with a fan located in the space beneath the heated floor panel.
The panel has an inlet self sealing port valve 18 and an outlet self sealing port valve 19 such as those available RS types 3872511 and 3872599. These are connected to water flow and return lines so that hot water is circulated through - 5 the hollow space defined between the base 10 and top 11 from the inlet 18 to the outlet 19. The floor panel provides a dimpled radiator for heat transfer to the room space as illustrated in Fig. 5.
In one arrangement (see Fig. 6) 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 (Figs. 7 and 8) 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.
In a particularly preferred arrangement the panel is inverted so that a dimpled side 30 is uppermost for enhanced heat transfer to the room space. In this case a heat sink material 25 may also be applied over the room side of the panel for enhanced heat transfer. The material 25 also provides a flat face.
The heat transfer system of the invention may not only replace trench heating but also conventional wall mounted radiators and as such could reduce heating bills by virtue of the greater efficiency of floor heaters which work at lower surface temperatures. Since they work at lower temperatures, typically around 27°C the system also lends itself to regenerative sources such as ground and solar sources.
A further enhancement is the potential to use the system as a means of dowsing a fire in a floor void by having holes on the underside of the floor panel sealed with a eutectic solder such that it melts off at a pre-determined temperature, for example 100°C, to release water from the panel. The effectiveness of this would be determined by the static head in the system and feed pipe size but both could be optimised for a particular system.
Fig. 2 illustrates the underside of a test system showing a self sealing valve arrangement and a ‘flying lead* style flexible supply pipe.
IE Ο 80 851 -6fig. 10 illustrates a heating panel 1 (typically 600mm square) on pedestals 40 which have built-in self sealing supply valves. Removal of the panel 1 from the pedestal automatically disconnects the fluid supply and seals both the panel ports and the supply pipes minimising fluid loss. Such a panel may be integrated into an existing floor or used in new installations.
One of the advantages of floor heating panel system of the invention above wall mounted radiators is that in a floor they can operate at much lower temperatures and are therefore safer and more economical to run, typically at 27C. Further improved economy may be achieved by adding a layer of insulation such as indicated in Fig. 3. The insulation may be a foam type (such as polyurethane or polyisocyanate), thus reducing heat radiated to the floor cavity.
The heat exchange medium may be a heating and/or cooling medium. The system may also include a heat pump.
The invention is not limited to the embodiments hereinbefore described which may be varied in detail.
