(3) feature
(3-1)
In above-mentioned heat exchanger unit 42, first heat exchanger 52 is formed with the first heat exchange area 500U of upside under
Side the first heat exchange area 500L, in upside, the first heat exchange area 500U is configured with the connection connecting with gas side connecting tube 6a
Mouthful, in downside, the first heat exchange area 500L is configured with the connector connecting with hydraulic fluid side connecting tube 5a.In addition, the second heat exchange
Device 62 is formed with upside the second heat exchange area 600U and downside the second heat exchange area 600L, in the second heat exchange area of upside
600U is configured with the connector that connect with gas side connecting tube 6a, and in downside, the second heat exchange area 600L is configured with and hydraulic fluid side
The connector of connecting tube 5a connection.
Therefore, when heat exchanger unit 42 is used as condenser, the internal state of heat exchange area is shown in Figure 13
State, supercooling region Sc1, the Sc2 being made of one or more flat perforated pipe are formed in the first heat exchange area 500L of downside
And downside the second heat exchange area 600L.In addition, in Figure 13, the mistake of the shadow representation refrigerant supercooling of region Sc1, Sc2
Cold-zone domain, the superheat region of the shadow representation refrigerant superheat of region Sh1, Sh2.
Herein, in the indoor unit of present embodiment 4 (air conditioner indoor unit), the wall portion 40w's than drain pan 40
At least part of supercooling region Sc1, Sc2 at upper end 40u low position configured with heat exchanger unit 42.Therefore, at this
In the indoor unit 4 of embodiment, at the position of the upper end 40u high of the wall portion 40w than drain pan 40 be configured with entire mistake
The structure of cold-zone domain Sc is compared, and can be improved heat exchanger effectiveness.
As supplement, the research of inventors according to the present invention is it is found that indoors in unit 4, in the upper of drain pan 40
At side space, the flow velocity (wind speed) of air stream becomes faster.Specifically, the wind speed profile between drain pan 40 and the inner wall of shell 31
Chart as shown in figure 14 is shown like that.Herein, in Figure 14, the longitudinal axis indicates the position in the up and down direction inside shell 31,
Horizontal axis indicates wind speed.As can be seen from Figure 14, indoors in unit 4, wind speed becomes faster in the upper space of drain pan 40.In addition, draining

Position on the lower carries out heat exchange area (the mainly upside heat exchange zone of the heat exchange between gaseous refrigerant and air
Domain 500U, 600U) it is configured at the upper space of drain pan 40.To sum up, by the heat exchanger unit 42 of present embodiment
In the case where as condenser, it is configured to more be configured with system in the upper space of the faster drain pan 40 of the wind speed of air stream
Faster upside the first heat exchange area 500U and upside the second heat exchange area 600U of the flow velocity of cryogen, so as to provide heat
The high indoor unit 4 of exchange efficiency.
(3-2)
In the first heat exchanger 52 of present embodiment, second on the downside of the area ratio of upside the first heat exchange area 500U
The area of heat exchange area 500L is big.The segmentation number of the refrigerant flow path of the first heat exchange area 500L of downside compares upside as a result,
The segmentation number of the refrigerant flow path of first heat exchange area 500U is few.Therefore, in first heat exchanger 52, with the first heat of upside
Exchange area 500U is compared, and at the first heat exchange area 500L of downside, can be improved refrigerant flow rates.
In addition, in downside, the first heat exchange area 500L formed cold-zone when first heat exchanger 52 is used as condenser
Domain Sc.Therefore, the position in the indoor unit of present embodiment 4, with the upper end 40u high in the wall portion 40w than drain pan 40
Place is compared configured with the structure of entire supercooling region Sc, can be improved heat exchanger effectiveness.
In addition, also being set up for second heat exchanger 62 with for identical discuss of the discussion of first heat exchanger 52.Cause
This, can be improved the coefficient of overall heat transmission of the second exchanger region 600L of downside.
