PROBLEM TO BE SOLVED: To facilitate a maintenance and a cleaning of appliances in a casing. SOLUTION: First, second and third cases 1a, 1b, 1c are connected laterally so as to constitute A casing 1. In the first case 1a, a control board 2 and a fan 3 are arranged vertically. An upper opening which communicates with an upper space is closed by an upper door 41a, while a lower opening which communicates with a lower space is closed by a lower door 41b. In the second case 1b, a heat exchanger 5 and a humidifier 6 are arranged laterally. A left opening 32a which communicate a left space is closed by a left door 42a, while a right opening 32b which communicates with a right space is closed by a right door 42b. In the third case 1c, an air filter 7 is arranged and a third opening 33 is closed by a third door 43. Doors 41a, 41b, 42a, 42b, 43 are pivotally mounted on the casing 1 by means of hinges in a frontward and backward direction (a direction perpendicular to a paper surface). An outside air enters the casing 1 through a return air opening 25 and then passes through the air filter 7, the heat exchanger 5, the humidifier 7, the fan 3 and a space defined behind the control board 2 and then is discharged outside through an air intake opening 15. |
