ある。 The present invention uses natural energy to install a heat absorber and a heat radiator in one device, and during the day, the heat medium is heated by the heat absorber. The object of the present invention is to provide a compact device that can cool the heat medium by emitting heat from the heat medium using the heat radiator, especially at night by utilizing the atmospheric window.

Thermal energy is heat radiation depending on the temperature held by the heat medium. Therefore, the thermal energy stored in the heat medium is conducted through the material with good thermal conductivity and guided to the heat radiator. The heat radiator has the property of emitting heat to the outside air only in a specific wavelength range depending on the temperature of the heat medium, and does not emit heat in other wavelength ranges. Therefore, thermal energy corresponding to the wavelength is emitted from the heat radiator to the outside air from the heat medium via the heat radiator. Therefore, the heat medium will be gradually cooled down.

This is because it is necessary to maintain the thermal energy of the heat medium constant, and if the heat medium is influenced by the external atmosphere, the heat conversion efficiency during heat absorption and heat radiation will decrease.
以下、本発明の実施例を図面と共に詳細に説明

吸収体、熱放射体への輻射伝熱を防止している。 A heat insulating container 1 that insulates a heat medium from the outside is a rectangular parallelepiped, has a concave cross section, and is formed of an iron frame 1a. The concave portion 2 of the heat insulating container 1 is filled with glass wool 2a having a thickness of 25 mm in order to obtain a sufficient heat insulating effect. Further, aluminum foil 3a is placed on the lower part and side wall of the inner part 3 of the heat insulating container 1 to prevent radiant heat transfer from the heat insulating container to the heat absorbing body and the heat radiating body.

It has a reflectance (that is, high absorption rate), and has a characteristic of high reflectance (that is, low emissivity) outside the wavelength range.
それ故、熱吸収体７は太陽光の熱エネルギーを

ことができるのである。 The spectral transmission characteristics of the KF film 8 used as the heat radiator are as shown by curve D in FIG.
It has a characteristic that the transmittance is low (high emissivity) in the wavelength range of 13 μm, and the transmittance is high outside the wavelength range. Generally, the peak wavelength of the thermal energy emitted by an object at around 30°C is about 10 μm, and most of it falls within the wavelength range of 3 to 50 μm. Therefore, most of the thermal energy emitted from the water 4a as the heat medium used in this embodiment overlaps with the selected wavelength range (8 to 13 μm) of the KF film 8 as the heat radiator 8. The KF film 8 is particularly useful at night when there is no external heat energy supply.
Since the thermal energy possessed by the heat medium can be radiated into the sky due to the radiant cooling effect, the heat medium can be cooled.

This is intended to block outside air and reduce heat loss due to internal convection.

とができる。 On the other hand, at night when there is little supply of thermal energy due to radiation from the outside, the heat energy supplied from the outside to the heat absorber/radiator A is mainly thermal radiation from the atmosphere, and the heat energy is emitted from the heat absorber/radiator A. The thermal energy is thermal radiation that is possessed by water 4a, which is a heat medium, and corresponds to the temperature. However,
Thermal energy held by the heat medium is transferred from the circulation pipe 4 to the KF film 8 via the copper plate 5 and copper black 6. The KF film 8, which is a heat radiator, has the property of radiating heat energy only in a specific wavelength range to the outside as described above. Therefore, the energy that has been thermally conducted from the circulation pipe 4 to the heat absorber 7 is sequentially
Heat is radiated to the outside world through the KF film 8, and the thermal energy of the heating medium gradually decreases. In this way, water, which is a heat medium, can be cooled.

In the absorption refrigerator 20, the hot water is used to cool the water inside the refrigerator 20.
そして、該冷水は恒温槽２７に一旦、保持し、
循環ポンプ３２によりフアンコイル３１の熱交換
部に送水する。そして、冷風として会議室等へ送
る。 Then, the cold water is temporarily held in a constant temperature bath 27,
The circulation pump 32 supplies water to the heat exchange section of the fan coil 31 . Then, it is sent to conference rooms, etc. as cold air.
夜間においては、吸放熱器Ａより直接冷水が得
られることから三方コツク１２，１３を切り、こ
の冷水を直接恒温槽２７へ供給し、ここで冷水を
保持する。この冷水をフアンコイル３１に供給し
て、冷風として会議室等に送る。 At night, since cold water can be obtained directly from the heat sink/dissipator A, the three-way pots 12 and 13 are turned off, and this cold water is directly supplied to the constant temperature bath 27, where the cold water is held. This cold water is supplied to the fan coil 31 and sent to a conference room or the like as cold air.
冬期には会議室等を暖める必要がある関係で、
日中では吸放熱器Ａより供給できる熱水を直接恒
温槽２７に保持し、フアンコイル３１に熱水を送
水して、会議室等に暖風を送出する。また過剰な
熱水は高温蓄熱槽１０に保管し、必要に応じて恒
温槽２７へ供給する。夜間においては吸放熱器Ａ
の熱媒体の循環を停止しておくことになる。 Due to the need to heat conference rooms during the winter,
During the day, hot water that can be supplied from the heat sink/dissipator A is directly held in the constant temperature bath 27, and is sent to the fan coil 31 to send warm air to conference rooms and the like. Further, excess hot water is stored in the high temperature heat storage tank 10 and supplied to the constant temperature tank 27 as needed. At night, heat absorber/radiator A
This means that the circulation of the heat medium will be stopped.
