PROBLEM TO BE SOLVED: To permit the removal of ammonia, reserved in a ceiling unit, by a method wherein a steam supplying means, capable of supplying steam to the inside space of a surrounding means, surrounding the main body of the device, is provided. SOLUTION: A steam supplying means is constituted of a heat medium supplying passage 6 and a solenoid valve 5, provided in a steam supplying passage 10 branched from the heat medium supplying passage 6, which a nozzle 7 for supplying steam with a wide angle is provided at the tip end of the steam supplying means and is arranged so as to be faced inward from the side wall of a surrounding means 2. In this case, an ammonia detector 9 is provided in the inside space of the surrounding means 2 while the ammonia detector 9 detects ammonia when the ammonia is leaked out of the main body 1 of the device and opens the solenoid valve 5 automatically by the output of a control means C to supply steam into the inside space of the surrounding means 2 through the steam supplying passage 10. According to this method, ammonia, reserved in a ceiling unit, can be removed simply.
