Definitions
- the present invention relates to a device for uniformly heating rooms, in particular heated living rooms, by balancing the temperature distribution between the ceiling and floor areas.
- the invention is therefore based on the object of providing a device with which a uniform temperature distribution in rooms can be achieved and at the same time heating energy can be saved. Applied to all known heating methods, the temperatures in the floor and ceiling areas should be harmonized.
- the advantages of this solution are in particular that the floor area can be kept warm and the heating output can be reduced by more than half.
- the cold air layer on the floor is displaced and unnecessary heating of the upper parts of the room can be avoided.
- Even temperature distribution at a sufficient level increases people's well-being. If, for example, air at a temperature of 25 ° C from the ceiling area is mixed with floor air of 17 ° C, a mixed air temperature in the entire room of approx. 21 ° C can be set. Due to the uniform temperature distribution, in particular the entire floor area of the apartment is avoided even with open doors. The previously existing, large heat loss through the ceiling due to the still standing warm air under the ceiling is also avoided.
- the built-in electric heating element can provide cost-effective heating of the room in the transitional period (spring or autumn) of a year.
- the device according to the invention is also intended to be a compact unit and can be assembled in an inexpensive and simple manner and subsequently and quickly and easily assembled in a room in an adapted manner.
- a simple assembly of the unit it is expedient to fasten the control unit to a front plate which is provided on the front with switches, display elements, a temperature sensor and the like and which can be inserted and fastened in a front recess in the column.
- the front panel has at least one circuit board equipped with electronic components on the back and plug-in connection parts extending to the rear wall of the column provided with a recess. As a result, all control-related and electronic components are provided on the front panel in a unit designed in the manner of an insert.
- the fan in the column causing an air flow from top to bottom and the heating element are arranged below the control unit, so that the electronic components are not exposed to a disadvantageously high temperature.
- the blower and the heating element are advantageously combined to form a structural unit which is suspended in an intermediate floor which is welded into the column, at a point below the opening for the front plate, so that the heating through this recess / Fan unit can be hooked into the mezzanine.
- the unit also has an air guide cylinder which surrounds the heating element, so that the air conveyed by the blower from top to bottom is directed in a concentrated manner and directly past the heating element.
- the compact unit "column” consists of an upper and a lower column part, which two parts are designed to be plugged together. This has the main advantage that the column can be adapted to different room heights.
- the lower column part preferably has the individual electronic components and the like, while the upper column part is essentially empty. This makes it possible to adapt the column to the given room height by cutting the upper part of the column.
- the butt joint resulting from the plugging together can be covered in a simple manner by a clip-like part.
- the device according to the invention or the column can be operated in connection with an existing external heating system while saving heating costs.
- This makes it possible to first heat the rooms in question exclusively as far as possible solely through the column or to ensure an even temperature distribution and only when the outside temperatures are such that the desired temperature is not achieved by the column alone more can be achieved or maintained to switch on the existing external heating.
- the connection of this heater can be largely delayed in this way, so that heating costs and energy cost savings of considerable amount are possible.
- Another advantage is that, especially in oil central heating systems, but also in gas heating systems, the exhaust gas generated by the heating system is reduced, thus contributing to environmental protection.
