In the case of a heater A conventional panel heater has a heat generating part 1 covered with a panel body 2 as shown in FIG. 1, and the heat radiation surface is a flat surface. The form of heat dissipation from the heat dissipation surface, that is, the form of heat supply into the room, is convection and radiation.The heat ratio of each is 50-60% for convection and 50% for radiation.

房感が生じるものとの差である。 Panel heaters are characterized by radiant heating, which results in the following advantages: It is a local heating system that directly radiates heat to nearby people, so heating energy can be saved. Good heating characteristics. In other words, the time from when the switch is turned on until a person feels a feeling of heating is short. This is the difference between a convection type, which does not give a feeling of heating unless the entire room is heated, and a radiation type, which gives a feeling of heating only when the panel heater warms up.

くはフアン、７は放熱器、８は三方弁である。In the case of air conditioners One type of cooling system that is being considered as one that uses natural energy is one that utilizes heat radiation into the sky at night (also called cold radiation or night radiation). At this time, the method of taking in cold heat, that is, the method of releasing heat, is to place a collector 3 on the roof through which a heat medium (water or air) passes, as shown in FIG. 2, and to radiate heat there. The collector 3 is also like a heat collection plate of a solar water heater, and is a flat plate with a meandering piping flow path formed therein. 4 is a circulation pipe, 5 is a heat storage tank, 6 is a pump or fan, 7 is a radiator, and 8 is a three-way valve.

い。qc′は吸熱を示す。 However, since the temperature of the heating medium is lower than the outside air temperature, it takes in a considerable amount of heat from the outside air through heat transfer, and as a result, the heating medium is only cooled by about 40 to 60% of the cold heat radiation qr'. qc′ indicates endotherm.

ルミ蒸着したものが用いられる。 An embodiment of this invention is shown in FIGS. 3 and 4. This embodiment is applied to a panel heater. In the figure, numeral 10 is a heat generating panel serving as a planar heat radiator, and a heat generating resistor 11 that generates heat when energized is embedded therein. A convection prevention member 12 is provided over the entire heat radiation surface of the heat generating panel 10 with a hollow layer 13 interposed therebetween. The four circumferences of the hollow layer 13 are sealed with peripheral walls 14. The convection prevention member 12 has a honeycomb shape, and is made of a material with low long wavelength absorption (high reflectance and transmittance) and low thermal conductivity. For example, a plastic film coated with aluminum vapor-deposited is used.
このように、発熱パネル１０の放熱面に対流防
止部材１２を設けたため、放熱面での対流が阻止

放射によるエネルギの割合が従来に比べて大幅に
増え、局所暖房による暖房エネルギの節約や暖房
感の立上り特性の向上が得られる。 As described above, since the convection prevention member 12 is provided on the heat dissipation surface of the heat generating panel 10, convection on the heat dissipation surface is prevented, and approximately 80% of the total calorific value becomes energy due to radiation. The remaining 20% is released by air conduction and some convection. in this way,
The proportion of energy generated by radiation is significantly increased compared to the conventional method, resulting in local heating that saves heating energy and improves the start-up characteristics of the heating sensation.

３mm以上のものとする。 The convection prevention member may be composed of a large number of parallel plates 15 as shown in FIG. 4, or may be in the form of a vertical and horizontal lattice, or an assembly of cylinders. Furthermore, as shown in FIG. 6, a film 16 having high transmittance for long wavelength radiation may be used as a convection prevention member. The film 16 preferably has a thickness of about 8 μm. When using film 16,
The hollow layer 13 between the film and the heat generating panel 10 is 3 mm or more.

減少させることができ、効率は1.5〜２倍となる。 Further, although each of the above embodiments is constructed as a panel heater, it can also be constructed as a collector for cooling and heat radiation. That is, instead of the heat generating panel 10 of each of the embodiments described above, a plate having a meandering heat medium flow path is used as a planar heat radiator. In that case, the conventional loss of 40 to 60% of cold radiation can be reduced to about 10%, and the efficiency is 1.5 to 2 times higher.
