Definitions
- the present invention relates to an air-conditioning apparatus including a heat exchanger provided with side plates and a method of manufacturing the air-conditioning apparatus.
- a heat exchanger employed in an air-conditioning apparatus is configured with, for example, a radiator fin, a tube and a side plate.
- the side plate is provided at end portions of the tubes, and the side plate has multiple holes formed thereon through which the multiple tubes are inserted.
- connection members that connect the multiple tubes are provided on the side plate.
- the connection member for example, a U-bent tube, a three-way bent tube, a bulge three-way tube and other tubes can be provided.
- the tube is a hairpin tube, the tube and the connection member are integrally formed.
- connection member provided to such a heat exchanger has various kinds of connection patterns (path patterns) that are complex. Therefore, a drawing on which a path pattern is provided is separately prepared. Then, a worker who manufactures the heat exchanger attaches parts to assemble the heat exchanger while alternately comparing the heat exchanger and the drawing providing the path pattern. When the number of parts related to the path pattern is large, it exceeds 100 per a single heat exchanger. Moreover, the parts include several types in some cases. Consequently, there is a possibility that the working hours are increased and a failure caused by an attachment mistake occurs.
- the parts related to the path pattern are mainly four types: the hairpin tube; the U-bent tube; the three-way bent tube; and the bulge three-way tube.
- these connection members there is no limitation to functions, an outer shape, attachment number and place, and so forth. Therefore, there is a possibility of increase in working hours due to inadequate confirmation of attachment places and inadequate confirmation of the connection member itself, and occurrence of failure caused by attachment mistake due to inadequate confirmation of attachment places and inadequate confirmation of the connection member itself.
- connection members when these connection members are attached by brazing, it is difficult to detach the members that have been attached once. Therefore, when an attachment mistake occurs, the whole heat exchanger including the radiator fins and the side plates has to be discarded.
- Patent Literature 1 there is disclosed a method of manufacturing a heat exchanger including multiple bent tubes.
- a heat exchanger is manufactured by attaching multiple bent tubes in advance to a support material having holes for inserting the bent tubes formed thereon, and fitting the support material to a tube inserted into a plate fin.
- Patent Literature 1 employs the support material to eliminate the confirmation of attachment places of the bent tubes, thereby, intends to improve workability in assembly of the heat exchanger.
- Patent Literature 2 there is disclosed a heat exchanger comprising a radiator fin, end plates, provided at both ends of the radiator fin and having a plurality of holes thereon to receive a plurality of tubes extending from one end plate to the other end plate through the plurality of holes, and markings provided on the end plates to show the insertion position of the C shaped bent of hairpin tubes.
- Patent Literature 1 since the heat exchanger disclosed in Patent Literature 1 requires the support material, manufacturing costs are increased. Moreover, in Patent Literature 1, attachment of bent tubes only is disclosed, and attachment workability when there are multiple connection members is not at all considered.
- the present invention has been made in view of the above circumstances, and provides an air-conditioning apparatus and a method of manufacturing the air-conditioning apparatus that reduce manufacturing costs and improve attachment workability even when there are multiple connection members.
- An air-conditioning apparatus of an embodiment of the present invention includes: a compressor, a first heat exchanger, an expansion unit and a second heat exchanger that are connected, by a pipe, in a refrigerant circuit through which refrigerant flows, wherein the first heat exchanger includes: a radiator fin, a plurality of tubes extending through the radiator fin and through which the refrigerant flows, and a side plate provided at end portions of the tubes, and having a plurality of holes formed thereon through which the tubes are extended, wherein, on the side plate, between the holes corresponding to the tubes to be connected, different markings corresponding to respective types of connection members (14) connecting the plurality of tubes (12) are provided.
- markings corresponding to the types of the connection members that connect the multiple tubes is provided on the side plate. Therefore, positioning is performed with ease without any support material. Consequently, the manufacturing costs is reduced. Moreover, the markings are different by respective types of the connection members, and thereby the connection member to be attached is recognized with ease. Therefore, the attachment workability is improved even when there are multiple connection members.

- Fig. 5 is a flowchart showing a method of manufacturing the air-conditioning apparatus 1 according to Embodiment 1 of the present invention. Next, the method of manufacturing the air-conditioning apparatus 1 will be described. First, on the side plate 13, the multiple holes 13a, through which the multiple tubes 12 are inserted, are formed. Specifically, on a metal plate in a flat-plate shape to serve as the side plate 13 of the first heat exchanger 4, the multiple holes 13a are formed by, for example, burring processing (step ST1).
- the markings 15 corresponding to the type of the connection member 14 that connects the multiple tubes 12 are provided between the holes 13a corresponding to the multiple tubes 12 to be connected. Specifically, between the multiple holes 13a, the markings 15 are inscribed by a marking jig (step ST2). Then, the upper end portion and the lower end portion of the metal plate are bent 90 degrees. Accordingly, the side plate 13 of the first heat exchanger 4 is manufactured (step ST3). Thereafter, the first heat exchanger 4 is manufactured by employing the side plates 13, and the air-conditioning apparatus 1 is manufactured by incorporating the first heat exchanger 4 thereinto.
- the compressor 3 sucks the refrigerant and compresses the refrigerant to discharge the refrigerant in a gas state of high temperature and high pressure.
- the discharged refrigerant flows into the first heat exchanger 4, and the first heat exchanger 4 condenses the refrigerant by heat exchange with the outdoor air.
- the condensed refrigerant flows into the expansion unit 5, and the expansion unit 5 expands the condensed refrigerant and reduces the pressure thereof.
- the refrigerant reduced in pressure flows into the second heat exchanger 6, and the second heat exchanger 6 evaporates the refrigerant by heat exchange with the indoor air.
- the indoor air is cooled, and thereby cooling of the indoor space is performed.
- the refrigerant evaporated and brought into a gas state of high temperature and low pressure is sucked by the compressor 3.
- the air-conditioning apparatus 1 according to Embodiment 1 is used in performing the cooling operation in this manner; however, the air-conditioning apparatus 1 may be configured to make it possible to perform, not only the cooling operation, but also the heating operation by providing a flow switching unit in the refrigerant circuit 2.
- Fig. 6 is a front view showing the side plate 13 of the first heat exchanger 4 in Embodiment 1 of the present invention.
- solid-line arrows indicate attachment positions of the connection members 14 that are attached to the side plate 13 on one end portion of the first heat exchanger 4 and flow directions of the refrigerant.
- broken lines indicate attachment positions of the connection members 14 that are attached to the side plate 13 on the other end portion of the first heat exchanger 4.
- each connection member 14 is attached in accordance with the types of the markings 15.
- the U-bent tube 14A is attached at the portion where the marking 15 of two parallel straight lines is provided.
- the three-way bent tube 14b is attached at the portion where the marking 15 of two straight lines that are orthogonally crossed is provided.
- the hairpin tube (the tube 12) is attached at the portion where the marking 15 is not shown. Then, the refrigerant flowing in from the inflow header 4a flows through the hairpin tube (the tube 12), the U-bent tube 14A, the hairpin tube (the tube 12), and the three-way bent tube 14b in this order.
- One of the refrigerant branched at the three-way bent tube 14b flows through the hairpin tube (the tube 12), the U-bent tube 14A, the hairpin tube (the tube 12), the U-bent tube 14A and the hairpin tube (the tube 12) in this order, and flows out to the first outflow header 4b.
- the other one of the refrigerant branched at the three-way bent tube 14b flows through the hairpin tube (the tube 12), the U-bent tube 14A, the hairpin tube (the tube 12), the U-bent tube 14A and the hairpin tube (the tube 12) in this order, and flows out to the first outflow header 4b.
- markings 15 corresponding to the types of the connection members 14 that connect the multiple tubes 12 are provided. Therefore, positioning is performed with ease without any support material. Consequently, the manufacturing costs are reduced. Further, the markings 15 are different by respective types of the connection members 14, and thereby the connection members 14 to be attached are recognized with ease. Therefore, the attachment workability is improved even when there are multiple connection members 14.
- this configuration reduces time for attaching the connection members 14 to the first heat exchanger 4. Moreover, since the attachment workability is improved, quality of the first heat exchanger 4 is improved. Further, even when the connection member 14 is attached by brazing, since occurrence of attachment mistake is suppressed, the risk of discarding the whole first heat exchanger 4 including the radiator fins 11 and the side plates 13 is reduced. This contributes to energy saving.
- the markings 15 are provided on the side plates 13 of the first heat exchanger 4, however, the markings 15 may be provided on the side plates 13 of the second heat exchanger 6.

- the markings 15 are provided on the side plates 13 of the first heat exchanger 4, however, the markings 15 may be provided on the side plates 13 of the second heat exchanger 6.
- the tube 12 is a hairpin tube, and the tube 12 and the connection member 14 are integrally formed. This configuration improves attachment workability of the hairpin tube.
- connection member 14 the U-bent tube 14A in the U shape is used. This configuration improves attachment workability of the U-bent tube 14A.
- connection member 14 the three-way bent tube 14b in the T shape is used. This configuration improves attachment workability of the three-way bent tube 14b.
- connection member 14 the bulge three-way tube 14c in a non-T shape is used, and the marking 15 indicating the attachment direction of the connection member 14 is provided on the side plate 13.
- This configuration improves attachment workability of the bulge three-way tube 14c, and the attachment direction thereof is recognized with ease.
- the markings 15 are provided by the marking jigs. This improves workability in providing the markings 15.
- the markings 15 are provided by the writing material. This improves workability in providing the markings 15.
- the markings 15 are provided by the stickers. This improves workability in providing the markings 15.
- the marking 15 is provided to cover the multiple holes 13a. This improves workability in providing the marking 15.
- the method includes: a step of forming multiple holes 13a, through which the multiple tubes 12 are inserted, on the side plate 13; and a step of providing, on the side plate 13, between the holes 13a corresponding to the multiple tubes 12 to be connected, different markings (15) corresponding to respective types of connection members (14) connecting the plurality of tubes (12).
- connection members 14 are different by respective types of the connection members 14, and thereby the connection members 14 to be attached are recognized with ease. Therefore, the attachment workability is improved even when there are multiple connection members 14.
