A drain tray 8 for collecting and exhausting 6 1 quid such as condensed water or hot water produced 7 by Ihe heat exchanger 3 is disposed under the heat 8 exchanger 3 A prefilter 9 which similarly collects dusts 9 to the filter 5 is disposed in the air suction port 2 0 at the bottom of the unit body 6.
11 Clean air ditfusers, in which filter members having 12 a number of vent holes are disposed, are respectively 13 formed in the side and lower surfaces of the air duct 7.
14 The air duct 7 is formed in an inverted trapezoidal sectional shape cut in tapered shape at both or one 16 side, and both shapes are selected according to the 17 disposing position of the clean unit 1.
~18 The air duct 7 is formed, for example, in the 19 length substantially corresponding to the width or `20 diameter of the room to be a clean room as shown in Fig. 3.
21 The air duct 7 is detachably or openably formed by 22 a clamping or butterfly structure at the lower portion 23 including the side and lower surfaces, thereby readily ~24 checking and maintaining in the air duct.
~25 The clean unit 1 composed of the unit body 6 and 26 the air duct 7 can be formed in the inverted L shape 27 that the air duct 7 is extended toward one side from one 28 unit body 6 as shown in -Fig. 1, in the inverted U shape 29 that the air duct 7 is suspended and extended between the two unit bodies as shown in Figs. 3 and 4, or other 1 various shapes, which may be selected in the shape of 2 the clean unit according to the shape and size of the 3 room to be cleaned.
4 In case of a clean room for a foodstuff industry, dustfree and a bacterial clean air is required, and a 6 sterilizer is preferably provided behind the filter 5 or 7 in the vicinity of the inlet of the air duct.
8 The drain tray 8 disposed in the lower portion of 9 the unit body 6 as one of the features of this invention will now be described in more detail.
The conventional drain tray 30 merely collects and 12 exhausts liquid as shown in Fig. 8, and is not entirely 13 ! considered for the air permeability in the structure.
14 ~ Thus, the air suction port 31 is necessarily formed in the lower side 33 of the unit body 32.
16 Thus, air is insufficiently sucked to the corners 17 and particularly in the vicinity of the floor in the 1~ room, and cannot be satisfactorily circulated. In 19 addition, the heat exchanger is disposed in the state ~0 for taking a space in the longitudinal direction due to ~1 the relation of the mounting position of the suction port, thereby causing a drawback of large size in the ~3 unit body.
The drain tray 8 of this invention is constructed, as shown in Fig. 5, that trough members of U-shaped 26 section are disposed at a suitable interval Q in two 27 stages in an inclined manner in one direction, and a 28 plurality of trough members lO of the upper stage and 29 a plurality of trough members ll of the lower stage are disposed at suitable intervals Ll and L2, respectively .

2 ~urther, the width L of the bottom 12 of the trough 3 member 10 of the upper stage is formed at least equal to 4 or wider than the interval L2 of the trough members 11 of the lower stage, and an arrangement is formed so that 6 the bottom 12 of the trough members 10 of the upper 7 stage is disposed on the upper extension of the interval 8 L2 f the trough members 11 of the lower stage, 9 Further, the trough members 10 and 11 of the upper and lower stages are disposed at an interval Q for ll passing the air, and an air passage 13 for passing the 12 air is formed of the interval L2 presented by the trough l3 members 11 of the lower stage, the interval between 14 the trough members 10 and 11 of the upper and lower 5 I stages, and the interval L1 presented by the trough 16 members 10 of the upper stage.
17 Liquid produced by the heat exchanger 3 is 1~ completely collected to the trough members 10 and 11 of the upper and lower stages, and the collected liquid is ~a exhausted externally from the members 10 and 11 through a drain passage, The air sucked by the air suction port 2 at the 23 bottom of the unit body 6 passes the prefilter and the ~4 air passage 13 formed at the drain tray, and is fed toward the heat exhanger 3.
~6 The drain tray in the clean room system of this 27 invention can completely clean the air in the room, and 28 have sound shielding and absorbing properties. The ~9 drain tray, for example, has an effect of silencing drive noise generated, for example, by the blower.
1 Fig, 7shows another example of a drain tray in 2 which trough members 14 and 15 of upper and lower stages 3 formed in U-shaped section are provided in combination.
4 The clean room system of this invention in which the clean unit l is disposed will now be described in 6 more detail. As shown in Figs. 2 and 3, a wall surface 7 16 and a ceiling surface 17 are composed of panel 8 members to form a clean room having desired shape and 9 size. The wall surface and the ceiling surface may, of 1~ course, utilize those of the constructed building.
11 , Then, the clean unit l composed of the unit body 6 and 12 ', the air duct 7 can be disposed in the formed clean room.
13 When the clean unit l is disposed, the unit body 6 is 14 , disposed in contact with the wall surface 16, and the 15 , air duct 7 is disposed along the ceiling surface. The 16 unit body ~ is designed to correspond to the height of 17 ~ the clean room, and *he length of the duct 7 is designed 18 to have the length substantially corresponding to the 19 width of the room.
~n the embodiment shown in Fig. 2, three clean 21 ` units l are disposed. However, the number of the clean 22 units l may be suitably increased or decreased 23 corresponding to the size of the room.
24 As shown in Fig. 3, an external air treating unit 18 is coupled through a duct with at least one unit body 26 so as to necessitate the introduction of the external air 27 into the room, 28 In the embodment shown in Figs. 2 to 4, the clean 29 1 unit of inverted U shape is employed, and three units are disposed at the four corners and the center of the room.

1 The unit body 6 of each clean unit 1 is fastened 2 to the wall surface 16 by simple clamping means such as 3 bolts and nuts, and the duct 7 is extended along the 4 ceiling surface 17.
In the clean room system of this invention, the 6 wall surface and the ceiling surface are formed of panel 7 members to form a clean room, the size of the clean unit is set corresponding to the height and width of the ~ clean room, and the clean unit is simply mounted in the clean room ll ' In the clean room system, the air diffuser is 12 Il formed in the air duct extended corresponding to the 13 width of the clean room, and the air is thus diffused in the "linear" state.
l, The operation of the clean room system of this 16 i~ invention will now be described. The air sucked in the 17 I' room from the air suction port 2 by the blower 4 or the ' air fed from the external air treating unit 18 is fed 9 through the filter 5 to remove dusts contained in the air, then sterilized through the sterilizer, when i provided, and then fed to the air duct. The clean air thus fed to the air duct is fed through the filter ~3 provided in the diffuser, and fed into the room in the 24 "linear" state, The clean room system of this invention has a ~6 feature that the air is diffused in the "linear" state 27 as described above, thereby removing the drawbacks of ~8 ; the conventional clean room system for diffusing the air 29 in the "planar" or "point" state.
3a The air diffused into the room is sucked from the ~ 8~
1 suction port 2 at the bottom.of the unit body 6 through 2 the prefilter 9 into the unit body 6. At this time, the 3 suction port 2 is formed at the bottom of the unlt body 4 6. Thus, the air can be circulated to the corners of the room, thereby satisfactorily cleaning the air.
6 The air sucked to the unit body 5 is again 7 circulated through the blower 4 in the air circulation 8 as described above 9 Further, the clean unit is formed merely by integrating the unit body and the air duct and fastening 11 ~ them in the room along the wall sur~ace and the ceiling 12 surface, thereby simply forming the clean room.
13 ,' In addition, the unit body has the drain train of 1~ '` special shape, thereby sucking the air from the bottom 1l of the unit body and circulating the air to the corners 16 , in the room to completely clean the room.

The conventional drain tray 30 merely collects and 12 exhausts liquid as shown in Fig. 8, and is not entirely 13 ! considered for the air permeability in the structure.
14 ~ Thus, the air suction port 31 is necessarily formed in the lower side 33 of the unit body 32.
16 Thus, air is insufficiently sucked to the corners 17 and particularly in the vicinity of the floor in the 1~ room, and cannot be satisfactorily circulated. In 19 addition, the heat exchanger is disposed in the state ~0 for taking a space in the longitudinal direction due to ~1 the relation of the mounting position of the suction port, thereby causing a drawback of large size in the ~3 unit body.
The drain tray 8 of this invention is constructed, as shown in Fig. 5, that trough members of U-shaped 26 section are disposed at a suitable interval Q in two 27 stages in an inclined manner in one direction, and a 28 plurality of trough members lO of the upper stage and 29 a plurality of trough members ll of the lower stage are disposed at suitable intervals Ll and L2, respectively .

2 ~urther, the width L of the bottom 12 of the trough 3 member 10 of the upper stage is formed at least equal to 4 or wider than the interval L2 of the trough members 11 of the lower stage, and an arrangement is formed so that 6 the bottom 12 of the trough members 10 of the upper 7 stage is disposed on the upper extension of the interval 8 L2 f the trough members 11 of the lower stage, 9 Further, the trough members 10 and 11 of the upper and lower stages are disposed at an interval Q for ll passing the air, and an air passage 13 for passing the 12 air is formed of the interval L2 presented by the trough l3 members 11 of the lower stage, the interval between 14 the trough members 10 and 11 of the upper and lower 5 I stages, and the interval L1 presented by the trough 16 members 10 of the upper stage.
17 Liquid produced by the heat exchanger 3 is 1~ completely collected to the trough members 10 and 11 of the upper and lower stages, and the collected liquid is ~a exhausted externally from the members 10 and 11 through a drain passage, The air sucked by the air suction port 2 at the 23 bottom of the unit body 6 passes the prefilter and the ~4 air passage 13 formed at the drain tray, and is fed toward the heat exhanger 3.

In the clean room system of this invention, the 6 wall surface and the ceiling surface are formed of panel 7 members to form a clean room, the size of the clean unit is set corresponding to the height and width of the ~ clean room, and the clean unit is simply mounted in the clean room ll ' In the clean room system, the air diffuser is 12 Il formed in the air duct extended corresponding to the 13 width of the clean room, and the air is thus diffused in the "linear" state.
l, The operation of the clean room system of this 16 i~ invention will now be described. The air sucked in the 17 I' room from the air suction port 2 by the blower 4 or the ' air fed from the external air treating unit 18 is fed 9 through the filter 5 to remove dusts contained in the air, then sterilized through the sterilizer, when i provided, and then fed to the air duct. The clean air thus fed to the air duct is fed through the filter ~3 provided in the diffuser, and fed into the room in the 24 "linear" state, The clean room system of this invention has a ~6 feature that the air is diffused in the "linear" state 27 as described above, thereby removing the drawbacks of ~8 ; the conventional clean room system for diffusing the air 29 in the "planar" or "point" state.
3a The air diffused into the room is sucked from the ~ 8~
1 suction port 2 at the bottom.of the unit body 6 through 2 the prefilter 9 into the unit body 6. At this time, the 3 suction port 2 is formed at the bottom of the unlt body 4 6. Thus, the air can be circulated to the corners of the room, thereby satisfactorily cleaning the air.
6 The air sucked to the unit body 5 is again 7 circulated through the blower 4 in the air circulation 8 as described above 9 Further, the clean unit is formed merely by integrating the unit body and the air duct and fastening 11 ~ them in the room along the wall sur~ace and the ceiling 12 surface, thereby simply forming the clean room.
13 ,' In addition, the unit body has the drain train of 1~ '` special shape, thereby sucking the air from the bottom 1l of the unit body and circulating the air to the corners 16 , in the room to completely clean the room.
