Air-conditioning apparatus and method of manufacturing air-conditioning apparatus

Abstract

An air-conditioning apparatus 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, multiple tubes extending through the radiator fin and through which the refrigerant flows, and a side plate provided at end portions of the multiple tubes, and having multiple holes formed thereon, through which the multiple tubes are extended, wherein, on the side plate, between the holes corresponding to the multiple tubes to be connected, a marking corresponding to a type of a connection member that connects the multiple tubes is provided.

Description

TECHNICAL FIELD[0001]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.BACKGROUND ART[0002]A heat exchanger employed in an air-conditioning apparatus is configured with, for example, a radiator fin, a tube and a side plate. There are provided multiple radiator fins and tubes, and the multiple tubes are inserted into the multiple radiator fins. 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. In the heat exchanger, connection members that connect the multiple tubes are provided on the side plate. As 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. Moreover, when the tube is a hairpin tube, the tube and the connection member are integrally formed.[0003]The connection member ...

AI Technical Summary

Benefits of technology

The present invention provides a design for a side plate with multiple tubes for connection. The side plate has markings corresponding to different types of connection members used to connect the tubes. This makes it easy to position the components without any additional material. Using different markings for different types of connection members improves the ease of attachment and workability even when multiple connection members are used. This reduces manufacturing costs.

Problems solved by technology

Consequently, there is a possibility that the working hours are increased and a failure caused by an attachment mistake occurs.

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.

Note that, when these connection members are attached by brazing, it is difficult to detach the members that have been attached once.
