PURPOSE:To make it possible to check for the presence or lack of liquid fuel and the liquid fuel leakage by supplying information from a constant fuel level type fuel adjuster to a central control device. CONSTITUTION:Air conditioners 5 are connected to respective terminal control device 4, and are controlled their operation by a central control device 1 via a signalling device 3. When the air conditioner 5 experiences a fuel shortage, it outputs a signal of fuel shortage by a float switch 15, and the central control device 1 illuminates a fuel shortage lamp 8 to warn in response to such information. If a needle valve 14 would not be completely closed because of a foreign substance etc. when overflowing fuel raised the float 17 to be drawn to a safety device 18 comprising a magnet, the float switch 15 rises because of the rising fuel level to cause a limit switch 16 to be actuated to warn the terminal control device 4 of the fuel leakage. Then, the terminal control device 4 shuts off the fuel supply. At the same time, the central control device 1 is warned of the fuel leakage, and illuminates a fuel leakage lamp 7 for warning. |
