Air-conditioning 100 described in this specification can be the split with the indoor unit and outdoor unit being separated from each other Formula air-conditioning, and air-conditioning 100 can refer only to the indoor unit of split-type air conditioner.

With reference to Fig. 1, air-conditioning 100 includes housing 110, multiple heat exchangers 120：121 and 123, fan 130 and guiding structure Part 210.

Air-conditioning 100 includes：Housing 110, with entrance 111 and outlet 113；Overhead heat exchanger 121, is arranged on housing In 110；And lower heat exchanger 123, it is spaced apart with overhead heat exchanger 121.Lower heat exchanger 123 can be located at top heat Below exchanger 121, so as to have the region Chong Die with overhead heat exchanger 121.

Also, air-conditioning 100 also includes：Guiding elements 210, for stopping overhead heat exchanger 121 and lower heat exchanger Space between 123 adjacent edge；And the component 220 that catchments, arrange and arrive guiding elements 210, in order to from upper heat exchange Device 121 is collected and discharges condensed water.

Housing 110 forms the profile of air-conditioning 100, and there is entrance 111 and outlet 113.

Also, operated by making the fan 130 in housing 110, air is introduced in housing by entrance 111.Afterwards, Air being heated or cooled during multiple heat exchangers 120, and the air being heated or cooled from there through Outlet 113 is discharged into the outside of air-conditioning.

Entrance 111 may be provided in housing 110 less than outlet 113 in place of, and fan 130 may be provided at outlet 113 Side.

Multiple heat exchangers 120 are arranged within the case 110 with the state being spaced apart with fore-and-aft direction along the vertical direction.

Reference Fig. 1, overhead heat exchanger 121 and lower heat exchanger 123 are separately arranged as along the width side of housing 110 To（Hereinafter referred to as X-direction）And short transverse（Hereinafter referred to as Y direction）It is spaced apart with preset distance.

Also, for convenience of description, in the first embodiment, by the upside of the Y direction being located opposite from Fig. 1 Heat exchanger be referred to as overhead heat exchanger 121 or first heat exchanger 121, and the Y direction that will be located opposite from Fig. 1 Downside heat exchanger be referred to as lower heat exchanger 123 or second heat exchanger 123.

In this case, overhead heat exchanger and lower heat exchanger 121,123 are arranged to, when seeing from entrance 111 When examining heat exchanger 121,123, both have the region for overlapping each other.

That is, overhead heat exchanger 121 and lower heat exchanger 123 are arranged to the region overlapped along Y direction. More specifically, relative to the upside of entrance 111, a part for the downside of overhead heat exchanger 121 and lower heat exchanger 123 A part be overlap.

At the same time, the length of the maximum of heat exchanger section is housed the space in the housing 110 of the heat exchanger Height Hc is limited.However, the air-conditioning suggestion of the present embodiment makes overhead heat exchanger multiple with lower heat exchanger 121,123 Region overlaps, to increase total heat exchange area.

It is additionally, since heat exchanger 120 and is divided into multiple heat exchangers 121,123, overhead heat exchanger and bottom heat is handed over The height L1 and L2 of parallel operation 121,123 can reduce respectively.

And, overhead heat exchanger and lower heat exchanger 121,123 can be respectively fin tubing heat exchanger.

Also, by reducing the height of overhead heat exchanger and lower heat exchanger 121,123, top heat can be reduced respectively The amount of the condensed water formed on the surface of exchanger and lower heat exchanger 121,123.

Specifically, if forming condensed water at the overhead heat exchanger 121, condensed water is under gravity to dirty Move the downside of overhead heat exchanger 121.Thus, the flowing of condensed water is as condensed water is to the downside of overhead heat exchanger 121 Front and then increase, so that the heat exchange performance of overhead heat exchanger 121 is poor.

However, overhead heat exchanger and lower heat exchanger 121,123 can be reduced respectively due to the air-conditioning of the present embodiment Height, therefore, it is possible to reduce the flowing of condensed water such that it is able to be respectively increased overhead heat exchanger and lower heat exchanger 121st, 123 heat exchange performance.

At the same time, it is important that can prevent air through respectively along X-direction and the spaced top heat of Y direction Space between the edge adjacent with lower heat exchanger 123 of exchanger 121 and flow.

Guiding elements 210 is executed between stop overhead heat exchanger 121 edge adjacent with lower heat exchanger 123 The function in space.

And, guiding elements 210 is executed and guides the air introduced by entrance 111 respectively through overhead heat exchanger 121 Function with lower heat exchanger 123.

That is, even if the region having a case that to overlap each other in overhead heat exchanger 121 and lower heat exchanger 123 Under, guiding elements 210 is also able to carry out the function of guiding air flow, with the whole height L1 in overhead heat exchanger 121 and Appropriate heat exchange is carried out on the whole height L2 of lower heat exchanger 123.

Used as a modification, guiding elements 210 may include：First connection part 211, positioned at the upper of lower heat exchanger 123 Side；Second connection part 213, positioned at the downside of overhead heat exchanger 121；And partition board portion 215, it is connected to the first connection part 211 Between the second connection part 213, between the edge adjacent with lower heat exchanger 123 to stop overhead heat exchanger 121 Space.
