The relay 5 has a structure in which the lower surface of the box body 43 is opened and closed for inspection and repair of the electromagnetic on-off valves 19 to 20, the flow rate control devices 25, 27, 33, electric parts and the like. As shown in FIG. 24, a service panel 45 that covers the entire lower surface of the repeater 5 is provided on the suspended lower ceiling surface. Further, since dew condensation occurs on the surface of the low pressure (low temperature) portion in the refrigerant circuit, the lower surface of the box body 43 is a drain pan, and the drain pipe 46 is provided so that the accumulated drain can be discharged outside the device. There is.

きくする。In the conventional air conditioner repeater 5 as described above, the larger the rated capacity, the larger the amount of refrigerant circulation, and the larger the size of the solenoid on-off valves 19 and 20. Further, the shapes of the first to third heat exchange portions 28 to 32 for taking the subcool become large. Furthermore, since these single parts are used while bending the pipes, a large space is required, and as a result, the box body 43 of the repeater 5 becomes large. Further, since the gas-liquid separator 24 has a columnar shape, a size corresponding to the diameter is required when the gas-liquid separator 24 is housed in the box body 43.
Increase the size of. Further, when connecting the pipe to the gas-liquid separator 24, the height dimension of the box body 43 is increased by connecting in the vertical direction, and connecting in the circumferential direction requires processing restrictions.
It is necessary to connect in a radial direction, the connection path with other components is restricted, the degree of freedom is reduced, and the size of the box body 43 is increased.

理時には邪魔になると言う問題がある。As described above, if the size of the box body 43 is increased, not only the manufacturing cost is increased, but also the service panel 45 provided for inspection and repair is enlarged, which deteriorates the interior design and gives the occupants a feeling of pressure. Further, there is a problem that the cost of construction becomes high because the commercially available inexpensive service panel cannot be used. Further, since the drain pipe 46 for draining the dew reaching the low pressure (low temperature) portion to the outside of the device is required, the construction cost becomes high, and water may leak to the ceiling and the living room. Further, since a large number of heavy parts are supported by a simple box structure, each part of the box 43 must be thickened to ensure rigidity, resulting in an increase in cost and an increase in product weight. Make construction difficult.
Furthermore, since there is no cable duct inside the box 43, the wiring running inside the box touches the high temperature part and the edge part, so a protective member is required, which not only increases the cost but also interferes with inspection and repair. There is a problem to say.

Also, if the block shape is a rectangular parallelepiped and the heat insulating material is attached, dew will not attach to the low pressure (low temperature) part,
There is no drainage. Further, when the gas-liquid separator has a flat shape, it becomes thin and the size of the box body becomes small. Further, when a heavy object is fixed by passing a beam over the upper part of the box body, the rigidity of the box body is increased, and the box body has sufficient strength even if it is thin. Also, when wiring is passed through the beam, the beam becomes a cable duct, and the wiring is in high temperature parts,
Do not touch the edge and do not disturb the service. In addition, the service parts can be reached by removing the side cover of the box, so a small service panel can be used for service. Also,
Since the control box doubles as a side cover, the number of parts is reduced.

At this time, do not provide drain piping. Control box 112 of the repeater 5
A commercially available 450-square inspection port will be provided on the lower ceiling surface in the vicinity. The operation of the refrigerant system is the same as that of the conventional one, but since heat insulation is applied to the low temperature portion, no condensation occurs and no drainage occurs. When the parts in the box 43 need to be inspected / repaired, the operator puts himself in through the inspection opening provided on the ceiling surface and removes the control box 112 or the panel 113 attached to the box 43 to open the opening 114. Insert and inspect and repair.

造コストも低減できるという効果も得られる。Since the present invention is configured as described above, since the first branch portion and the second branch portion are arranged in the box body as one block of a block, respectively, the box body is The effect of becoming smaller can be obtained. Further, since the block shape is a substantially rectangular parallelepiped and the heat insulating material is attached, dew does not adhere to the low pressure (low temperature) portion, and the effect of not generating drainage can be obtained. Further, since the gas-liquid separator has a flat shape, the gas-liquid separator becomes thin, and the size of the box body can be reduced. Further, since the beam is passed over the upper part of the box body to fix the heavy object, the rigidity of the box body is increased, and the effect that the box body has sufficient strength even if it is thin. . Further, since the wiring is passed through the beam, the beam serves as a cable duct, the wiring does not come into contact with a high temperature portion or an edge, and does not disturb the service, so that the maintainability is improved. Also,
Since the service parts can be accessed by removing the side cover of the box, the service can be performed with a small service panel, and thus the effect of improving the maintainability can be obtained. In addition, since the control box also serves as the side cover, the number of parts is reduced, so that the manufacturing cost can be reduced.
