When 2 angles of α are smaller, unit back side panel is directly hit in outlet air, produces vibrations and noise, when α 2 is larger, outlet air
Speed is high and uneven, and noise is big.Air conditioner using a rated cooling capacity as 3.5kw is adopted as testing machine, air conditioner unit
With two folding heat exchangers, it is 3 row Ф, 5 copper pipes often to roll over heat exchanger, and two rows of U pipes sums are managed for 18 U, and two folding heat exchanger angles are 74
Degree.Machine packet size is 440*200*750, and when air conditioner operates in most high-grade, the test data of noise is as shown in following table one（Angle
Spend unit：Degree, noise unit：Decibel）：
Table one：Noise test data under different 2 angles of α
| α2 | Noise | Remarks |
| 10 | 43.1 | Side plate vibrations are larger |
| 20 | 42.8 | |
| 50 | 41.7 | |
| 80 | 43.6 | |
| 90 | 45.3 | Wind speed is uneven |

, it is necessary to increase unit thickness during 3 angle too small, when 3 angles of α are excessive, outlet air directly impact lower side panel and cause to vibrate it is larger,
Consider noise and machine packet size, it can be deduced that more preferably scope is 20 °~70 ° to α 3.
In above-mentioned each embodiment, heat exchanger 20 can be single folding heat exchanger or two folding heat exchangers.With reference to Figure 11
Shown, when heat exchanger 20 rolls over heat exchanger for list, single scope for rolling over the angle theta 1 between heat exchanger and horizontal plane is 20 ° to 90 °,
Machine packet size can effectively be reduced, because the section U numbers of this small unit are generally 12~24 U pipes, such heat exchanger is cut
The length in face is a definite value, and when 1 very littles of θ, unit section depth size is bigger, and be easy to cause heat exchanger draining not
Freely, when θ 1 is very big, unit height dimension is relatively large.Using the unit that a rated cooling capacity is 3.5 kilowatts as testing machine, adopt
Heat exchanger is rolled over single, heat exchanger is managed for 18 5 bronze medal U of Ф, under different 1 angle cases of θ, the unit sectional dimension such as institute of following table three

Table three：Unit sectional dimension test data under different 1 angles of θ
| θ1 | Unit sectional dimension（Depth * height） |
| 20 | 450*250 |
| 50 | 390*250 |
| 90 | 245*280 |
It can be drawn from the data of upper table three, when θ 1 is from during 20 ° increase to 90 °, can effectively reduce unit
The size of depth direction (245mm is reduced to by 450mm).
When heat exchanger 20 is two folding heat exchangers, first heat exchanging part and second of the two folding heat exchangers including the setting that is in the shape of the letter V is changed
Hot portion, the scope of the angle theta 2 between the first heat exchanging part and the second heat exchanging part is 20 ° to 150 °, when 2 angles of θ are smaller, heat exchange
Device inlet air region is too small, and unit air quantity is less than normal, and when angle increases to certain angle, upper and lower heat exchanger distance is more than centrifugation blade
During size, distance increase is more it is necessary to increase the height dimension of unit, is by 3.5 kilowatts of unit of a rated cooling capacity
Example：Unit uses two folding heat exchangers, and it be 3 row Ф, 5 copper pipes often to roll over heat exchanger, and two rows of U pipes sum is 18 U pipes, converts heat when two
Angle theta 2 between device changes, in unit operation when most high-grade, wind quantity test data and the unit thickness such as institute of following table four
Show（Angular unit：Degree, air quantity unit：Cubic meter per hour, dimensional units：Millimeter）：
Table four：Air quantity and unit thickness test data under different 2 angles of θ
| θ2 | Air quantity | Unit thickness |
| 20 | 523 | 200 |
| 74 | 614 | 200 |
| 90 | 637 | 235 |
It can be seen that from the data of upper table four when θ 2 increases to 90 ° by 20 °, air quantity is continuously increased, the thickness of unit
It increased.
According to different design forms, two folding heat exchangers can be integrated bending forming, or by two separate exchangers
The bending place of spicing forming type, the first heat exchanging part and the second heat exchanging part can be with wedge angle transition, can also arc transition.
In the air pipe indoor machine of air draught type, since the U length of tube direction air volume adjustment of heat exchanger 20 is relatively uniform by changing
