  Further, in the heat exchanger chamber 21, a heat insulating material 52 that also serves as a seal is attached to the inner surfaces of the left and right side surfaces 4 and 5 and the inner surface 7A of the main body front panel 7, and further, the upper surface 22A of the heat exchanger 22, that is, A heat insulating material 53 that also serves as a belt-like seal is affixed to the surface facing the drain pan 23, and these heat insulating materials 52, 53 improve the heat insulation and sealing performance of the heat exchanger 22 on the outlet side. ing.

  Here, the process for incorporating the heat exchanger 22 into the main body 1A in the production line will be described. In the present embodiment, several members are incorporated in advance when the heat exchanger 22 is manufactured, and the heat exchanger assembly 200 is performed. In the assembly process in the production line, the heat exchanger assembly 200 is assembled in the main body 1A.

Specifically, as shown in FIG. 5, the heat exchanger assembly 200 includes a gas pipe 36 and an oil pipe 37 of the heat exchanger 22 of the pair of heat exchanger fixing plates 50 and 51. The heat exchanger fixing plate 50 that fixes the side to be disposed is fixed in advance to the heat exchanger 22 with screws 70A and 70B, and a sensor holder 56 is disposed on the blowing surface of the heat exchanger 22 to hold the sensor. The temperature sensor 54 is held and fixed to the tool 56, and a belt-shaped heat insulating material 53 is attached to the upper surface of the heat exchanger 22 (the contact surface with the drain pan 23).
On the other hand, the other (right end in FIG. 5) heat exchanger fixing plate 51 is fixed to the main body 1A in advance by screws 71.

Moreover, in the heat exchanger assembly 200, as shown in FIGS. 5 and 6, the heat exchanger fixing plate 50 is attached to the tube plate 60 at the end of the heat exchanger 22 to which the heat exchanger fixing plate 50 is not fixed. A U-groove 60 </ b> A that is recessed in the extension direction of the exchanger 22 is formed, and a sensor wire 57 extending from the temperature sensor 54 is inserted into the U-groove 60 </ b> A and folded back to the suction side of the heat exchanger 22.
Moreover, in the strip-shaped heat insulating material 53 affixed on the upper surface of the heat exchanger 22, the end 53A on which the heat exchanger fixing plate 50 is not fixed extends from the heat exchanger assembly 200, A release paper (not shown) is attached to the back surface of the end portion 53A.

In the production line, the heat exchanger assembly 200 is assembled into the main body 1A through first to third steps described below.
The first step is a step of positioning the heat exchanger assembly 200. That is, in this first step, the heat exchanger assembly 200 is inserted into the main body 1A, and the heat exchanger assembly 200 is positioned with reference to the heat exchanger fixing plate 51 fixed in advance to the main body 1A.

The subsequent second step is a step of screwing and fixing the heat exchanger assembly 200. More specifically, in the second step, the heat exchanger fixing plate 50 fixed in advance to the heat exchanger assembly 200 is fixed to the main body 1A with screws 72, and the heat exchanger fixing plate fixed in advance to the main body 1A. 51 and the end of the heat exchanger assembly 200 are fixed by screws 73A and 73B.
At this time, as shown in FIG. 7, the open end of the U groove 60A in which the sensor wiring 57 is fitted is closed by the heat exchanger fixing plate 51, and the sensor wiring 57 is held in the U groove 60A.

  Further, as shown in FIG. 5, the heat exchanger fixing plate 50 fixed in advance to the heat exchanger 22 is fixed at two locations, upper and lower, by screws 70A and 70B. Since these screws 70A and 70B are tightened at the stage of assembling the heat exchanger assembly 200, that is, before being attached to the main body 1A, the pitch of the screws 70A and 70B is widened so that the lower screw 70B is relatively low. Even if it becomes, it cannot be tightened. Thus, since the pitch of the screws 70A and 70B can be increased, the fixing strength between the heat exchanger fixing plate 50 and the heat exchanger 22 is maintained at a sufficiently high strength. Therefore, the heat exchanger fixing plate 50 having such a screwing structure is used to fix the end of the heat exchanger 22 on the side where the gas pipe 36 and the oil pipe 37 are extended to the heat exchanger 22. The portion having the largest load is fixed with sufficient strength.

  On the other hand, in the heat exchanger fixing plate 51 fixed in advance to the main body 1A, as shown in FIG. 6 and FIG. 7, screw holes 75A and 75B are formed at two places on the upper and lower sides. Screws 73A and 73B are passed through 75A and 75B, and heat exchanger assembly 200 is fixed. The screw holes 75A and 75B of the screws 73A and 73B are generally shifted upward (in the drain pan side) in the figure as compared with the positions of the screws 70A and 70B for fixing the heat exchanger fixing plate 50. The position of the lower screw hole 75B is higher than that of the main body front panel 2A, and is provided at a position that can be seen from the front side. Accordingly, the screws 73A and 73B can be passed through the screw holes 75A and 75B using a screwdriver without being obstructed by the main body front panel 2A.

  Further, the upper screw hole 75A is formed in the vicinity of the upper end of the heat exchanger fixing plate 51 so that the pitch of the screws 73A and 73B is maximized even when the position of the lower screw hole 75B is increased. Thus, the fixing strength of the heat exchanger assembly 200 is maintained as much as possible.

  Next, the third step is a step of completely attaching the heat insulating material 53 and the temperature sensor 57. As described above, the heat insulating material 53 and the temperature sensor 57 are preliminarily incorporated in the heat exchanger 22 as the heat exchanger assembly 200. In the third step, the heat insulating material 53 and the temperature sensor 57 are connected to the main body 1A side. The work of attaching to the member is performed.

Specifically, in the heat exchanger fixing plate 51 fixed in advance to the main body 1A, as shown in FIG. 6, the upper end of the heat exchanger fixing plate 51 is bent in an L shape to form a locking piece 51B. When the heat exchanger assembly 200 is fixed to the heat exchanger fixing plate 51 in the second step, the locking piece 51B covers the upper end of the tube plate 60 of the heat exchanger 22. And in a 3rd process, the release paper affixed on the edge part 53A of the heat insulating material 53 is peeled off, this edge part 53A is affixed on the locking piece 51B, and the affixing work of the heat insulating material 53 is completed.
Further, in the third step, as shown in FIG. 7, an operation for filling the gap between the sensor wiring 57 and the U-shaped groove 60 with the putty 80 is performed, whereby the sensor wiring 57 is fixed to the U-shaped groove 60. Thus, the mounting operation of the sensor wiring 57 is completed.

  Thus, according to the present embodiment, one heat exchanger fixing plate 50 of the pair of heat exchanger fixing plates 50 and 51 is fixed in advance to the heat exchanger 22 to constitute the heat exchanger assembly 200. The other heat exchanger fixing plate 51 is fixed in advance to the heat exchanger chamber 21 of the main body 1A, and the heat exchanger assembly 200 is inserted into the main body 1A when the heat exchanger assembly 200 is incorporated into the main body 1A. After positioning on the other heat exchanger fixing plate 51, one heat exchanger fixing plate 50 is screwed and fixed to the main body 1A, and the heat exchanger assembly 200 is screwed and fixed to the other heat exchanger fixing plate 51. I did it.

  Thus, when the heat exchanger 22 is incorporated into the main body 1A in the production line, the heat exchanger fixing plate 51 is screwed to the main body 1A, and the heat exchanger fixing plate 50 is screwed to the heat exchanger 22. Since the work is omitted, the assembly process is simplified and the assemblability is improved.

  In particular, according to the present embodiment, the heat exchanger fixing plate 51 fixed in advance to the heat exchanger chamber 21 of the main body 1A has screw holes 75A and 75B for screwing the heat exchanger assembly 200 in the main body. Since it is formed at a position higher than the front panel 2A, that is, a position facing the front of the main body 1A, the heat exchanger assembly 200 can be screwed with a screwdriver or the like without being obstructed by the main body front panel 2A. . Therefore, unlike the prior art, there is no need to provide an insertion hole (see FIG. 8) in the main body front panel 2A and screw it through the driver through the insertion hole, so that the heat exchanger can be easily attached. Further, the sealing performance is prevented from being impaired by providing the insertion hole.

  Further, according to the present embodiment, the heat exchanger assembly 200 is configured by fixing the heat exchanger fixing plate 51 in advance to the end of the heat exchanger 22 where the gas pipe 36 and the oil pipe 37 extend. ing. Thereby, the screw fixing between the heat exchanger fixing plate 51 and the heat exchanger 22 can be performed without considering the incorporation into the main body 1A, so that the portion where the load on the heat exchanger 22 is the largest is obtained. The screwing position can be designed freely so that the fixing strength is sufficient for fixing.

  Further, according to the present embodiment, since the heat exchanger assembly 200 is configured by previously attaching the heat insulating material 53 and the temperature sensor 54 to the heat exchanger 22, the heat insulating material is assembled when the heat exchanger assembly 200 is incorporated into the main body 1A. The attachment work of 53 and the temperature sensor 54 becomes easy.

  In particular, according to the present embodiment, the sensor wiring 57 is previously extended from the blowing side to the suction side of the heat exchanger 22 through the sensor wiring 57 in the U groove 60A provided in the tube plate 60 of the heat exchanger 22. When the heat exchanger assembly 200 is screwed to the heat exchanger fixing plate 51, the open end of the U groove 61A is closed by the heat exchanger fixing plate 51, and the sensor wiring 57 is held in the U groove 61A. As a result, the sensor wiring 57 can be easily routed and fixed in the production line.

  Further, a heat insulating material 53 for sealing is provided in advance in the surface of the heat exchanger assembly 200 that contacts the drain pan 23, and one end 53 </ b> A of the heat insulating material 53 is extended from the heat exchanger assembly 200. When the heat exchanger assembly 200 is screwed to the fixing plate 51, one end 53A of the heat insulating material 53 is attached to the heat exchanger fixing plate 51, so that the operation of attaching the heat insulating material 53 in the production line is easy. become.
