ている。As is well known, the thermosiphon A has a sealed structure consisting of an ascending pipe 1, a gas-liquid separation drum 2, a descending pipe 3, and a transport pipe 4.
Inside these, liquid Freon 113 (
Ccl2F-CCF2). The gas-liquid separation drum 2, in which liquid fluorocarbon and fluorocarbon vapor are in equilibrium, is placed at the top, and the rising pipe 1 and the descending pipe 3 rise about 5 to 10 times low. Further, the transport pipe 4 extends horizontally for approximately 100 to 300 m, and its end is formed into a heat radiation coil to constitute a part of the fan coil unit 5, from which hot or cold heat can be supplied to the heat demand section. That's what I do.

The other end of the heat exchanger 7 is connected to the heat pump B for heat input. Further, a heat exchanger 6 for transferring heat pump BOy thermal output (hot heat in heating operation, cold heat in cooling operation) to the fluorocarbon is installed in the main body of thermosiphon A at the lower end of riser pipe 1.

ポンプＢの吸熱源を調整するバルブを示す。In the figure, 9 is a vacuum/pressure pump, which is connected to the gas-liquid separation drum 2, and is connected to the gas-liquid separation drum 2 when switching between heating and cooling operation.
8 in the figure indicates a valve that introduces outside air and adjusts the heat absorption source of heat pump B.
次に前記のごとき装置を用いての動作について説明する
。Next, the operation using the above-mentioned apparatus will be explained.

熱は気液分離ドラム２内に発生する凝縮潜熱である。First, the case of heating operation will be described. The heat pump B is operated using the outside air introduced through the valve 8 and the input from the heat exchanger 7 as the heat source X to obtain a high temperature y and a low temperature exhaust gas 2. In this case, as described above, the heat from the heat exchanger 7 is the latent heat of condensation generated within the gas-liquid separation drum 2.
一方、熱交換器６を介してフロン液は加熱され、沸点に
達すると上昇管１内で沸騰気泡が発生する。On the other hand, the fluorocarbon liquid is heated through the heat exchanger 6, and when it reaches its boiling point, boiling bubbles are generated in the riser pipe 1.

線矢印で示した。Using the density reduction in the riser pipe 1 due to the boiling bubbles as a driving force, the heated Freon liquid is sent through the transport pipe 4 to the heat demand section and is used for indoor heating via the fan coil unit 5. The flow and temperature level are shown in FIG. 2 and indicated by solid arrows in FIG.

ｍ２Ｇ （飽和温度７０゜Ｃ以下）であるため熱サイフ
オンＡの圧力は比較的低圧に保持され、安全である。As shown in FIG. 4, the saturation pressure and saturation temperature curve of the Freon 113 increases as the saturation temperature increases. Since the temperature of the heated Freon liquid is almost equal to the saturation temperature, the transportation temperature can be adjusted by the pressure of the gas-liquid separation drum 2, but the adjustment range is up to 2 kg/a
m2G (saturation temperature 70°C or less), the pressure of thermosiphon A is maintained at a relatively low pressure and is safe.

温度レベルを第３図に示す。If the pressure of the gas-liquid separation drum 2 is set to below atmospheric pressure using the vacuum pump 9, the fluorocarbon liquid heated by the fan coil unit 5 will boil even at about 20°C, and the transport pipe 4
Bubbles rise through the downcomer pipe 3, the fluorocarbon liquid flows in the opposite direction to that during heating (see the dotted line arrow in Figure 1), and the cooled fluorocarbon liquid flows into the fan coil unit 5. Further, in the gas-liquid separation drum 2, the freon vapor is condensed by the heat exchanger 7, and the internal pressure of the drum is maintained at a low pressure. This flow and temperature levels are shown in Figure 3.
