PROBLEM TO BE SOLVED: To simplify cleaning work or the like of a heat exchanger by enabling to expose the heat exchanger without detaching a dust-proof net. SOLUTION: The dust-proof net 17 covering a front surface 12D side of the heat exchanger 12 is provided. The dust proof net 17 consists of a left divided net 18 and a right divided net 19 divided into a left and a right direction of a heat exchanging device 11, each divided net 18, 19 is constructed to be able to move a left and a right direction. Consequently, at a time of cleaning dust or the like adhering in the heat exchanger 12, the heat exchanger 12 can be exposed to outside by only moving the left divided net 18 and the right divided net 19 covering the heat exchanger 12 in the right direction and the left direction. Consequently, cleaning work of the heat exchanger 12 can be simply done without detaching each divided net 18, 19. COPYRIGHT: (C)2006,JPO&NCIPI
