Abstract

A portable building (1, Fig. 1) has a floor 4, walls (2, 3, Fig.1), and a roof 5, in which the roof and walls comprise an inner and outer layer which are spaced apart to define a void. Warm air resulting from solar gain rises and is trapped in the roof void 10. An opening 12 in the inner layer connects the interior of the building to the roof void 10. A controller (15, Fig. 3) receives signals from a sensor (17, Fig. 3) which senses the temperature of air in the roof void 10 and outputs control signals to air flow control means (14, Fig. 3) to control the flow of air from the void into the building. The air flow control means (14, Fig. 3) may be a fan or one or more flaps which selectively obscure the opening 12. The target temperature inside the building may be set by a user with a thermostat. The outer layer of the roof may be formed from metal sheets coated with a dark coloured coating and the walls may comprise insulation and reflective foil sheets.

Description

A PORTABLE BUILDING
This invention relates to improvements in portable buildings.
S Portable buUdings are known and are widely used in many industries, especially construction, When a large construction project is being undertaken, there is often a need to provide accommodation for workers if there is no suitable permanent building close to the constructions site. These buildings are typically designed to be moved on the bed of a lorry to the site, where they can be temporarily located until they are no longer needed. They will then be lifted onto a lorry and removed. Although designed to be used as temporary accommodation, many are of sufficiently high quality that they may be used for considerable periods of time before they are removed.
Many types of portable building are known, and in general they comprise a floor, insulated walls, and insulated roof, a door and one or more windows. They may include interna' partitioning. may be stackabk and interconneetable with other buildings to form a larger building. Metal wafls and roofs are commonplace due to the ease of construction and the high levels of security they provide for times when the buildings are unoccupied, Where they are to be used in cold climates, or during the winter months, the buildings will include heating, typically in the form of electric heaters. The cost of heating portable buildings can be high, and form a significant part of the costs of locating and using the buUdings. Metal buildings, for instance, need to be heavily insu'ated if they are to be used in either hot of cold climates.
An object of the present invention is to ameliorate the problems associated with heating of portable buildings.
According to a first aspect the invention provides a portaHe buflding having a floor, walls, and a roof, in which the roof and walls comprise of an inner and outer layer which are spaced apart to define a void within which warm air can rise when solar gain occurs and arranged so that the warm air becomes trapped in the roof void, And further comprising: an opening in the inner layer which connects the interior of the buflding to the roof void, an air flow means that controls the flow of air through the opening from the void into S the building in response to control signals, a temperature sensing means which produces at least one signal indicative of tile temperature of the air inside the void, and a controller which receives the temperatures signals at an input and outputs control signa's dependent on the temperature signals to the airflow means, The air flow means may comprise a fan which can suck air out of the roof void and blow it into the building. The fan may be located inside the void, to blow air through the opening, or inside the building inner layer to draw air through the opening.
The air flow control means may alternatively or additionally comprise one or more flaps which selectively obscure the opening, or partially obscure the opening.
The opening may be located at a lower part of a wall of the building, for instance 30cm or less above the floor. There may be multiple openings. Each opening may be connected to the roof void.
The controller may be adapted to cause the air flow control means to move air from the void into the building when the air is warmer than that inside the building and when the temperature inside the building is be'ow a target temperature.
The controller may include a user operable input that can be programmed or otherwise set to define the target temperature inside the building.
The user operable input may comprise a thermostat that additionafly measures the temperature inside the building (not the temperature within the void). The output from the thermostat may be fed to an input of the controller, The controfler may be adapted to provide dwell periods in which no air is being drawn into the building even when the actual temperature inside the building is below the target to allow the air in the void to become heated by solar heating of the roof, The heated air that is stored in the roof void will be used to heat the internal space of the buflding when the controller, typicafly a thermostat, calls for heat, the warm air S stored in the roof void, if warm enough, is drawn into the internal space via a fan systcm and blown into the internal space until the set internal temperature is reached.
Once up to internal temperature the warm air is no longer required and the room thcrmostat will in turn switch the fans off.
The portable building may include an electric heater that when operating will heat up the interior of the building.
The controller may turn off the heater whenever the fans are drawing warm air into the interior from the void.
The heater may be thermostaticafly controHed so that even when turned ON it only supplies heat as required to keep the room at a demanded temperature as set by the thermostat, The controller may operate the heater to provide additional heat to the interior at times when the heated air in the void is insufficient to raise the temperature of the interior to the desired level.
The controfler may be configured to operate the heater during dwell periods when heated air is being built up in the void and where the temperature of the interior would otherwise drop below the desired level.
The temperature sensing means may comprise a thermostat located in the roof void, or between the opening and the roof void.
The outer layer of the roof may comprise one or more metal sheets. For example, the svafls and roof may be defined by the outer layer of a metal box shaped structure, which may be corrugated to provide strength to the material, The or each sheet may be coated with a dark coloured coating, ideally matt black, to maxiniise the solar gain heating of the roof. The outer layer may therefore be the outer most surface of the roof that provides the weatherproofing of the building.
S AUernativey, the outer layer may be covered by an additiona' protective layer of matcrial, Any protective layer should be chosen for its ability to allow energy from the sun to be transferred to the olLter layer as heat.
The roof and also at least one of the wafls may comprise an inner and outer layer with a void between them. Alternatively, only the roof may include a void and a pipe may be provided which connects the void to the opening.
The inner layer of the roof and waHs may comprise of a thick (for examp'e 100mm minimum) layer of insulation which is foil backed to maximise the entrapment of hcated air and to minimise thc transfcr of hcat from the void into thc building.
The insulation may be used to create the void between the outer ayer in both the wafls and roof Most prcfcrably the insulation includes rcflective foil sheet which faccs the outer layer across the void to reflect heat towards the outer layer.
An opening may be provided in the floor below the wall void through which fresh air is drawn into the void, allowing constant resupply of fresh air which is heated and rises into the roof void and stored ready for use, The inner layer may be provided with an additional opening through which air in the building can be recirculated back into the void. This may be located close to the bottom of the wafl, The void should be arranged so as to encourage the free movement of air within the void from the roof to the opening. A space of at least 25mm or at least 50mm between the inner ayer and outer ayer may be provided over a major part of the walls and 75mm to 100mm for the roof The provision of a void which contains air that is heated passively by the sun and then selectively drawn/pushed into the buflding can greatly reduce the heating costs of the building by making good use of the free energy of the suns rays.
There will now be described, by way of example orfly, one embodiment of the present invention with reference to thc accompanying drawings of which: Figure 1 is a perspective view of a portable building in accordance with the present invention; Figure 2 is a cross section through the building along the centre line showing the construction of the roof and walls: and Figure 3 is a simplified block diagram showing the function of the electrical circuit that controls the air moving fan of the passive heating system.
As shown in Figure I a portable building I comprises a box of generally rectangular cross section. The height of the box h is around 3m. width w around 3m and length 1 around 6m. It may be made in different sizes of course, as long as it allows sufficient interior height and width to function as a building.
The outer shell of the building comprises metal sheeting that forms the walls (of which two walls 2 and 3 can be seen in Figure 1), floor 4 and roofS. The sheets are wdded together a'ong their edges. with additional reinforcement provided where the walls and roof meet, A door 6 is provided in one wall to allow entry and egress, and a window 7 is also provided which is covered by a protective shutter, The outer skin of the roof of the building is coated all over in a matt black paint which ensures that the meta' roof heats up during the day as sunlight strikes the roof Within the outer shell is an inner shell, This comprises walls S of stud type walling / timber frame which supports the insulation and allows the internal plasterboard wall sheets to be hung, and an inner roof ayer ceiling board, again plasterboard 9. Other materi&s could be used for the inner layer. The inner ayer of the roof is spaced from the outer layer of the roof 5 to form a void 10. The spacing between the layers is generally constant and around, for example a spacing of 25mm wall and 100mm roof.
This forms a void which will contain air that wifl be heated by the heating of the outer layer of the roof Insulating material II is provided in the void and is supported by a timber frame. The thickness of the insulation is more than the thickness of the void so that a gap remains between the insulation and the outer layer of the roof. In this example the insulation includes a heat reflective outer later of silver foil that helps reflect hcat back into the void.
The insulation material 11 and inner layer 8. 9 could, of course, comprise one and the same as a structural insulated panel.
At a lower part of a wall of the building 1 an opening 12 is provided which connects the inside of thc building which will contain the occiLpants to the void. This opening 12 has a cross section of around I OOcm2 in this example, but could be more or kss.
The inner ayer of the roof and walls 8, 9 is otherwise seakd. but is open at the bottom where fresh air can enter the void 19, and only the void not the internal of the building. The internal wall is sealed to the floor 4.
The opening 12 is connected to the roof void through pipe work 13, allowing air to flow along the pipe work to the opening.
Close to the opening, inside the void, an air flow means in the form of a fan 14 draws air from the void through the pipe work 13 and into the inside of the building. As shown in Figure 3. the fan 14 is controlled by a controllcr 15 which receives signals form a user operable input 16 that defines a target room temperature and a temperature sensor 17 located in the roof void. It may also receive a signal from a further temperature sensor 18 indicating the actual temperature inside the building.
In a simple arrangement, as shown, the controller 15 is integrated into the circuit that controls an electric motor that turns the fan 14. A flap (not shown) may also be provided which closes off the opening when the fan is not in use.
In use, sunlight strikes the metal roof and walls which heats air in the roof void. If the temperature of the air is above the temperature of the inside of the building and the temperature inside the building is below the user set target, the controller causes the fan to move air from the void into the building to provide passive heating.
The applicant has appreciated that using heat in this way can greatly reduce the amount of forced heating of the building that would otherwise be needed. In the case of a building that is heated using electric radiators this can produce a significant reduction in the cost of heating the building. Where the energy is not from a carbon neutral source, the passive heating will also greatly reduce the amount of C02 that is emitted as a result of maintaining a target temperature inside the building, A'so shown in this embodiment is an additional electric heat source, This is controlled by the controller which opens and close a contactor that in turn turns the heater on and off according to whether the fan is running (heater off) or is not running (heater on).
The heater in turn is thermostaticafly controlled so that even when ON it on'y applies heat if the temperature in the room drops below the demanded level.
