は冷熱を供給できるようにしている。 As is well known, 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, and inside these is liquid fluorocarbon 113 (Ccl 2 F-CcF 2 ) as a heat medium. filled with. The gas-liquid separation drum 2, in which liquid fluorocarbon and fluorocarbon vapor are in equilibrium, is placed at the top, and the ascending pipe 1 and descending pipe 3 rise approximately 5 to 10 meters. Further, the transport pipe 4 extends horizontally for approximately 100 to 300 m, and its end is formed into a heat dissipation coil and is connected to the fan coil unit 5.

本体中、上昇管１の下端部に設置する。 In the figure, 7 is a cooling heat exchanger disposed inside the gas-liquid separation drum 2 to condense the vapor of the freon 113 and keep the pressure inside the drum 2 constant. Connect the end to heat pump B for heat input. In addition, a heat exchanger 6 for transferring heat output of the heat pump B (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 the riser pipe 1.

２内に発生する凝縮潜熱である。 First, the case of heating operation will be described. Heat pump B is operated using outside air introduced through valve 8 and input from heat exchanger 7 as heat source x to obtain high temperature y and low temperature exhaust z. 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.

た。 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. 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.

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 2Kg/cm 2 G (saturation temperature 70℃ or less) ), the pressure of thermosiphon A is maintained at a relatively low pressure and is safe.

れる。 Next, the case of cooling operation will be described. The heat pump is operated using outside air and input from the heat exchanger 7 as the heat source x to obtain low temperature y and high temperature exhaust gas z. The fluorocarbon liquid is then cooled through the heat exchanger 6.

の温度レベルを第３図に示す。 If the pressure of the gas-liquid separation drum 2 is set below atmospheric pressure using the vacuum pump 9, the fluorocarbon liquid heated by the fan coil unit 5 will boil even at around 20°C, and the The air bubbles rise through the fan coil unit 5, the fluorocarbon liquid flows in the opposite direction to that during heating (see the dotted arrow in FIG. 1), and the cooled fluorocarbon liquid flows into the fan coil unit 5. Furthermore, in the gas-liquid separation drum 2, the fluorocarbon vapor is condensed by the heat exchanger 7,
The pressure inside the drum is maintained at a low pressure. The temperature level of this flow is shown in FIG.
