Definitions
- the invention relates to radiant heating with at least one a jet pipe at least partially surrounding housing with lateral Reflector areas, one that directs the heat radiation downwards has upper reflector area and open at the bottom for heat radiation is, the heat radiation emerging from the housing is a distribution curve with lowered centrally under the housing and relative on both sides has increased course.
- Such radiant heating systems are characterized by a low Convection heat and relatively economical energy consumption. Because of the difficulty of having a radiation distribution that is beneficial for human well-being to achieve, the use of previous ones was limited Radiant heating to higher room heights than e.g. 4 meters so that as an area of application in particular hall-like lounges or work rooms came into question. For more details, see the paperback for heating + air conditioning 92/93, page 362 ff.
- the invention has for its object a radiant heat Provide the type specified above, which also in lower rooms conveys a pleasant feeling of warmth.
- the distribution curve can e.g. determined by the geometry of the jet pipe be, for example, that the side portions the radiation area are larger in cross section than the lower and upper.
- the design can be such that the cross section of the Beam tube trapezoidal with base at the top or bottom, oval with vertically aligned large diameter, triangular with top or base below or rectangular with vertically aligned long ones Sides is. It is provided that the jet pipe at least in sections selective coating, the radiation components can be additionally appropriately by varying the transmittance.
- Another measure to determine the distribution curve of heat radiation is that under the beam pipe a reflective lower reflector element is arranged.
- the training can be such be that the lower reflector element has lateral deflection surfaces, the the incident heat radiation is essentially symmetrical to the side deflect or that the lower reflector element is designed as a horizontal strip is.
- the vertical portion can be determined over the width of the strip reduce practically as desired, so that such training the Radiant heating is advantageous for low room heights.
- the control of the heat radiation can be further varied in that the lateral reflector areas are aligned vertically. In this way the jet pipe can also be optically shielded so that the appearance radiant heating is favored.
- the distribution of heat radiation can also be influenced by the fact that reflector areas as vapor-coated glass strips are formed. Depending on the strength of the vaporization or coating the glass strips can be a more or less large proportion the heat radiation are reflected.
- a suitable distribution curve with reduced vertical heat radiation in the central area can be achieved in that the upper reflector area in Cross-section sloping or curved sections on both sides towards the edge having.
- the radiant heat heater 10 shown in FIG. 1 has a housing 9 on, in between the lateral housing boundaries a perpendicular to Jet tube 8 extending plane is arranged.
- the housing 9 Above the Beam tube 8, the housing 9 has an upper reflector region 1 a central horizontal section and laterally adjoining the Sections inclined downwards. The sloping sections are on their free end from vertically downward extending lateral Limited reflector elements 2.
- Insulation means 7 are provided to suppress heat loss, and the housing 9 is closed on its upper side with a housing cover 6.
- a lower reflector element is located vertically below the jet pipe 8 3 arranged, which in cross section essentially the shape of a Angle or triangle with the top pointing up and the bottom lying Owns base.
- the cross section of the jet pipe 8 has a large proportion of steep radiation areas on, which are additionally provided with a coating 5.
- 1 is a trapezoidal cross section with an overhead one Base side shown.
- the from the jet pipe 8 exiting heat radiation in a variety of ways Reflection and / or transmission can be influenced to a vertical of the Radiant tube 8 downward heat radiation in its intensity decrease and to the side at a radiation angle ⁇ (see Fig. 2) radiated heat radiation defined.
- Reflection and / or transmission can be influenced to a vertical of the Radiant tube 8 downward heat radiation in its intensity decrease and to the side at a radiation angle ⁇ (see Fig. 2) radiated heat radiation defined.
- Reflection and / or transmission can be influenced to a vertical of the Radiant tube 8 downward heat radiation in its intensity decrease and to the side at a radiation angle ⁇ (see Fig. 2) radiated heat radiation defined.
- ⁇ see Fig. 2
- the side surfaces the jet pipe 8 can be relative to the upper and lower portions of the Radiation area 4 can be designed larger to a correspondingly larger lateral To achieve radiation.
- the measures described result, for example, in a distribution curve b according to Fig. 2.
- the radiation intensity or irradiance E clearly reduced while in the subsequent angular range at about 30 ° each Maxima of the distribution curve occur.
- the lower reflector element 3 removed or replaced by another reflector element, e.g. as horizontal strip can be designed that completely or only partially is reflective and partially permeable, e.g. the vertical portion of the Distribution curve less weakened, as the distribution curve a shows.
- the vertical portion in both cases is in favor of lateral angular ranges radiated heat radiation decreases, the efficiency is practically hardly reduced.
- the upper reflector area 1, the side reflector area 2 and the lower reflector element 3 suitable distribution curves can be varied accordingly generate, a stronger one especially for low room heights Lowering the heat radiation in the middle area is advantageous.
- the optics of the radiant heating can also be used with coated strips vary so that e.g. as built-in, surface-mounted or suspended Radiation bodies can also be used in offices or waiting rooms can.
