<P>PROBLEM TO BE SOLVED: To provide a drainage discharging device which operates a discharging pump with the optimum output in accordance with the size of the inside diameter of a drainage discharging pipe, and surely discharges the drainage in a drainage tank. <P>SOLUTION: The drainage discharging device includes the drainage tank 14 for storing the drainage generated in a latent-heat heat exchanger 4, water level detection means 20 and 21 for detecting a water level of the drainage tank, the drainage discharging pipe 16 for leading out the drainage from the drainage tank to a discharging part 15, a discharging pump 17 for forcibly discharging the drainage, and a discharging control means 24 for operating the discharging pump in accordance with the water level detected by the water level detection means. The discharging control means reduces the output of the discharging pump when the discharge required time of the drainage is equal to or less than first reference time, and increases the output of the discharging pump when the discharge required time of the drainage is equal to or more than second reference time, and varies the first reference time and the second reference time in accordance with the varied output of the discharging pump. <P>COPYRIGHT: (C)2011,JPO&INPIT |
