The equipment includes a tepidarium room with walls of insulation boards, the sides of which that face the room carrying an electrically conductive meander band that serves as a surface heating element covered with an insulating plastic foil and shielded by a metal foil. The equipment includes means to increase the transfer of heat from the heating element to the heat-radiating surface of the insulation boards, a coating which reflects radiant heat on the parts of the room enclosure that are not directly heated, ventilating openings in the walls close to the cold floor by which the room air temperature can be lowered draft-free at least 4°C. below the mean radiation temperature, a control device for the automatic adjustment of the mean radiation temperature, a fault current safety switch, and an alarm system activated upon failure of the energy supply or upon occurrence of an impermissibly high temperature.

Equipment for the homogeneous radiant air-conditioning of a room, a tepidarium and/or a lounge with space enclosures (wall, doors, or ceiling) assembled of individual insulation boards, the sides of which that are facing the room are carrying an electrically conductive meander band that serves as surface heating element, which in turn is covered with an insulating plastic foil and shielded by a metal foil, characterized by means that increase the transfer of heat from the heating element to the heat-radiating surface of the insulation boards in such a manner that the temperature of this radiating surface is largely the same as the temperature of the heating element and is kept homogeneous; by connecting-at the edge at each end of each meander band by means of welded joints-stronger lead-in foil strips, attached to the rigid plastic foam board, with the metallic covering of the support foil of the metallic meander band that is firmly attached to the plastic foam board, said covering serving as heating element; by a coating-which reflects radiant heat and is protected against corrosion on the parts of the room enclosure that are not directly heated, particularly on the cold floor that is covered, in addition, in the areas of traffic, with skid-resistant netting having a mesh size of approximately one centimeter, which is impregnated with synthetic material; if desired, by a lounge in the tepidarium or a lounge with minitepidarium positioned over it, which consists of a bed frame sitting horizontally on legs, or suspended from the ceiling, over which a relatively coarsely knotted net is stretched, and which admits the heat radiation of the tepidarium or from the electrically heated insulation boards attached to the bed frame, as well as the cooler room air to the human body lying on it and to most of the surfaces on which the body is lying; by a ventilation of the room with cool air, entering through ventilating openings in the walls close to the cold floor, the size of which can be regulated, or through a ventilating slit of adjustable height between wall or electrically heated insulation board and floor, by which means the room air temperature can be lowered draftfree at least 4°C. below the mean radiation temperature of all radiant and reflecting areas of the room enclosure; possibly by a special impedance of the heat transfer from the electrically heated walls to the room air by means of a reinforcement of the boundary layer by an air cushion that is held in place by mechanical means at the surface of the vertically positioned electrically heated insulation boards, but permits the heat radiation from the insulation boards to enter the room unhampered; by a control device for the automatic adjustment of the mean radiation temperature of all heated surfaces of the insulation boards facing the room or the human body to a uniform and chronologically constant temperature that can be freely selected in the range from 22°C. to 45°C.; by a fire protection achievable with a fault current safety switch, based on the fact that the heating element is already disconnected from the power supply net at a fault current of 30 mA, which flows off from the heating element, via softened or burnt out insulation, to the ground shield, during overheating or spark-over at any point of the meander band through which the heating current flows, before the overheated spot or the spark-over can ignite the rigid plastic foam of the insulation board; by an alarm system to the tepidarium that is activated upon failure of the energy supply from the power line, or upon activation of a fault current saftey switch connected in series with the surface heating elements, or upon occurrence of an impermissibly high temperature, i.e., upon failure of the electronic control of the radiation temperature.
