PURPOSE:To contrive the improvement of efficiency in maintenance work by a method wherein members, which necessitate maintenance, in respective units are withdrawn and/or inserted into the same direction through the openings of respective units. CONSTITUTION:A composite unit is constituted of casings Vc, Cc, Dc, Hc, Fc for a base unit VU, an electric dust collector unit CU, a deodorizer unit DU, a humidifier unit HU and a fan unit FU which are connected in series. Members, which necessitate maintenance, or a heat exchanger 1, a rough dust filter 90, respective elements C1, C2, D1, D2, H1, H2, ventilating fans 20, 21 are withdrawn and/or inserted into the same direction through the openings 80-82, 71-78 for maintenance of respective units VU, CU, DU, HU, FU. According to this method, the works of maintenance can be facilitated. |
