In alternative embodiments, the air flow generating device consists of any other appropriate air flow generating apparatus which may lack a housing and/or fan.

[0023] In the exemplary embodiment, the heat delivery unit 8 is comprised of at least one infra-heater. The design of the heater may vary within the scope of the present invention.

[0024] The heat delivery unit 5, such as preferably an infra-heater, is preferably powered by electrical energy. The electrical energy can be supplied to the heat generating unit from a variety of energy sources or storage devices for electrical energy.

[0025] The electrical energy supply system, a subsystem 2 to system 1 is in a first embodiment of the vehicle's electrical system for the supply of electrical energy. The subsystem is preferably used to charge system accumulators.

[0026] In alternative embodiments of the system 1, electrical energy is supplied (supplied) from at least one fuel cell or the like. The fuel cell may be a previously known fuel cell or the like.

[0027] In additional alternative embodiments, the supply of electrical energy may be via solar cells. The solar cells can be defined as being part of the system or by a separate device or devices.

[0028] In further alternative embodiments, the supply of electrical energy can be accomplished via supply of 110 V to 400 AC. Alternatively, another suitable voltage level suitable for the purpose may be used. It may also be conceivable that the system is powered by direct current of varying voltage for the purpose of the appropriate voltage level.

[0029] In further alternative embodiments of the present system, the electrical energy may be stored in at least one external electrical energy storage device prior to use in the system.

[0030] In another alternative embodiment of the system, the system is used to heat, for example, a truck's interior when the driver of the truck stops and sleeps. The heater is heated with electrical energy from a second battery, belonging to the system, not the vehicle.

[0031] Referring again to FIG. 1B, an exemplary embodiment of the present system will be described in more detail. In this embodiment, the system is a portable system, alternatives are referred to as the portable heating system used in a truck and used to heat the vehicle in connection with, for example, a break/rest stop or during the night. The system is explained step by step with reference to the respective box in the box diagram.

[0032] 1. The vehicle's electrical system is used in the exemplary embodiment as subsystem 3 to charge the accumulators included in subsystem 3 (FIG. 1B) using modern switch technology. For example, 10-30 volts are used in the system. Alternatively you can have input for other voltages such as 110-400 AC for example. In further alternative embodiments, other voltage levels suitable for the purpose may be used. In alternative embodiments, other solutions such as subsystem 1 (FIG. 1B) are used, for example, with solar panels and/or fuel cell technology (thus increasing the applications).

[0033] 2. As mentioned in paragraph 1, the electronics are designed so that regardless of voltage, charging and battery status are checked efficiently and safely, i.e. controls the battery level and temperature during the charging phase for safety reasons, but also to ensure charging status regardless of voltage source so that power is available when required (break).

[0034] 3. The GTC power bank in subsystem 3 (FIG. 1B) is designed so that the capacity is adapted to the need, i.e. a different amount of Amperimeters for different needs, which is determined by the power requirement (size of the space) and the time standing still without adding energy (Accumulators like NiFe when they have high energy density). The GTC Power Bank could also be fuel cell technology.

[0035] 4. The control unit in subsystem 4 (FIG. 1B) is designed to control temperature, i.e. the climate of the compartment/cab/caravan/restroom/space with several possible applications. By controlling the added power and checking the fan's/fans' speed to provide the selected temperature in the cab. The controller also monitors temperature and battery status. The control unit also includes a timer/clock function.

[0036] 5. The fan-integrated heater in subsystem 2 is made with highly efficient IR emitting panels that heat the interior of the space, the excess heat that is a by-product of the IR production generated is utilized by the fans and fabrics to direct the air to cool the rear panel, this cooling air is then taken care of and can be piped to targeted areas. This is to achieve the highest possible energy efficiency, while at the same time airflow reaches areas not reached by the IR heat.

Procedure for Using the System

[0037] When using the system, this is moved to at least one space or the like where it will be used. The space can be a variety of spaces where there is a need for heating. The space is in the preferred embodiment of at least one space in a vehicle such as the interior of the vehicle. In a preferred embodiment, the present invention is used in the cab of a vehicle. For example, the cab can be the cab of a truck.

[0038] After the system has been moved to the space to be used, the system connects to the electrical system in the space or in close proximity to the space. The system is used in this embodiment in such a way that the system is connected to the vehicle's electrical system. Through the control electronics, the accumulators are loaded into the system when the vehicle is in use. The stored energy in the accumulator unit is used to drive the heat generating unit when the vehicle is not operational so that at rest the system can heat the vehicle without risking starting problems when the vehicle is to be used. In alternative embodiments, it is conceivable that the system is not connected to said one system without the energy being supplied to the system via at least one solar cell, at least one fuel cell or other device that generates electrical energy.

[0039] The system's heat-generating device, or devices, is installed in the space. Installation can be done by using a variety of techniques. For example, the heat transfer unit can be hung or laid on a surface. Subsequently, the control system senses temperature in the space and that at least the said heat dissipating unit at temperature in the internal space below a certain predetermined temperature emits heat to air passing through or past the heat generating unit.

[0040] In the detailed description of the present invention, design features may be omitted, as will be apparent to those skilled in the art within the scope of the invention. Such obvious design features are included to the extent required for a satisfactory function to be obtained for the present invention.

[0041] While some preferred embodiments have been described in greater detail, variations and modifications of the invention within the scope of the invention may become apparent to those skilled in the art, and all such are considered to fall within the scope of the claims.

ADVANTAGES OF THE INVENTION

[0042] With the present invention, a number of advantages are achieved. With the present invention, at least one of the problems disclosed in this patent application is eliminated or minimized. Furthermore, a significantly more environmentally friendly system is created than with existing types of systems. The system also has the advantage that it can be portable and able to be moved between different vehicles/spaces. This combination of heating technologies is considered to be unique and very effective. In addition, heating is quicker due to the fact that the interior stores heat from the IR heater, for example, in and out of the vehicle.
