Definitions

• the present invention relates to a method and an arrangement to heat a floor by using an airborne floor heating system and to assure that moisture that may exist will be removed from the heat carrying air. More exactly the invention relates to a technique that will work together with big heat emitting surfaces, e.g. a floor or a wall heating system having a very small energy inertia.
• the main object of the present invention is to obtain a technique making sure that that moisture, if any, in or in connection to a floor system of joists is effectively removed by a dehumidification technique forming part of an airborne floor heating system.
• Yet another object of the present invention is to obtain a technique allowing in a simple way an appropriate integration of said technique in a floor structure to minimise the laying of conduits.
• This also includes a low propelling force to circulate the air in the floor heating system at the same time as it is possible to speed up the heating without neither the input temperature, the propelling force nor the sound level of the floor heating system need to be significantly increased.
• the invention also has the possibility of a reduced heating being obtained in a very simple way seen from the technical control point of view.
• channel system for the heated air in close connection to the upper surface of the finished floor said channel system will work as a floor heating system.
• heating batteries are arranged to emit heat to the air circulating in the channel system.
• the heat released when the moisture in the air is condensed e.g. over an expansion element forming part of a closed refrigerant circuit with compressor and condensing element, will in fact be transferred to said refrigerant being circulated in a closed refrigerant circuit.
• this arrangement will act both as a heat pump and a dehumidifier and is preferably activated only when needed for dehumidifying the air being circulated in the floor, e.g. when the humidity of the air has reached a certain predetermined level.
• an expansion element forming part of a heat pump system the condensation of the humidity in the air can take place by using a heat exchanger battery, through which cold water to water heater is transferred.
• the system is controlled by thermostat valves in the same way as in a radiator and a change of speed of the fan or fans circulating the air in the closed channel system will give a possibility of a simple modification of the power output from the floor heating system.
• Fig. 1 is a diagrammatic view from above of a floor having equipment according to the invention arranged between a system of joists;
• Fig. 2 is section along line 2 - 2 in the system of joists of the floor according to fig. 1 ;
• Fig. 3 is a diagrammatic section through a system of joists of a floor, a channel system and through a fan convector including a heat battery and a condense battery; and wherein
• Fig. 4 is a section through a floor laid directly onto a ground plate of concrete using the technique according to the invention.
• FIG. 1 a diagrammatic view from above of a floor 1 having equipment according to the invention arranged between a system of joists 3 is shown.
• a unit of a fan/convector - generally designated 2 - has a fan device 2A and a heat battery 2 B of the flowing through type as convector element.
• the channel system with an over pressure part Al, A2 and an under pressure part B l, B2 are formed by flowing channels 4, here shown adapted in the upper floor plate (see also fig. 2 and 4).
• fig. 2 is shown how the fan/convector unit 2 is arranged between the joists 3 in a system of joist of the floor, and can in this way be built in and isolated in said system of joists.
• these channels are preferably divided in several parallel flow channels with the view of lowering the flowing resistance and allow a forced flow of air through said channels in an increased need of heating.
• these are arranged in connection to distributing (C, E) and collecting (E, D) larger channels.
• the fan/convector unit 2 has been shown built-in between the joists in the system of joists in the embodiment according to fig. 1 and 2 it is instead placed outside the system of joists in the embodiment according to fig. 3.
• the channels are shown in direct connection to an upper floor plate.
• a heat exchanging battery 2C is shown in the main channel for the airflow.
• This exchanging battery can be used for condensing humidity in the circulating air, in one way by using cold water (e.g. for warm water heating) or a refrigerant (e.g. forming a part flow of an expansion circuit of a heat pump).
• a folio 6 is also shown which has been laid between the upper plate 5 and an underlying insulation 7.
• the insulation 7 in turn is placed above a layer of sand 8 covering the moulded ground plate 9.
• the folio 6 will let moisture pass to the circulating heated air, and when needed i.e. when the moisture content of the air exceeds a predetermined value (e.g. 50 % relative humidity) this is indicated by detecting means in connection to the fan/convector unit, a dehumidification arrangement 2 C is connected to the fan/convector unit (or to some other suitable location in the main flow) to dry the circulating air.
• the dehumidification can takes place continously or when needed.
• this dehumidification arrangement can form part of a (part) flow of a refrigerant circuit of a heat pump passing inside a heat exchanger and over which the air is outwardly flowing to be cooled as the refrigerant circuit in this case constitutes the colder expansion side of the heat pump.
• the same heat exchanger can be used as the condensing side of the heat pump, i.e. to add heat to the air circulating in the floor channels.
