Detailed Description
The present invention is further illustrated by the following examples, but is not limited to the details of the description.
Among the prior art, need set up the heat exchanger in the wind channel in the tuber pipe machine and carry out the heat transfer to gas, the heat exchanger can produce the comdenstion water, consequently in the heat exchanger below, the inside in wind channel can set up the water collector and accept the comdenstion water that produces on the heat exchanger to avoid the comdenstion water to drip influence tuber pipe machine's result of use, current tuber pipe machine all only considers the water collector and can all be to the effect of accepting of comdenstion water, all be to the fan or to the heat exchanger on the improvement to tuber pipe machine's heat transfer effect. However, through the research of the applicant and the analysis of the simulation experiment data, it is found that, in the heat exchange process of the air duct machine, all components in the air duct can influence the airflow in the air duct, and only considering the fan or the heat exchanger can only play a part of the purpose of increasing the heat exchange effect, in order to ensure the receiving effect of the water receiving tray, the water receiving tray has certain height which plays a role of blocking at the lower part of the air duct, meanwhile, in order to reduce the occupied space of the air duct machine and reduce the distance between the fan and the heat exchanger as much as possible, the water receiving tray is also close to the fan, so that the water pan has great influence on the air inlet and outlet of the fan, namely the water pan is also an important factor for influencing the air flow in the air duct, how to avoid the influence of the water pan on the air volume of the fan is an important parameter capable of effectively improving the heat exchange efficiency of the air pipe machine.
To this end, as shown in fig. 1 to 4, the present invention discloses a duct type air conditioner, including: the air conditioner comprises a shell 1, wherein an air port is formed in the shell 1; the fan 2 is rotatably arranged in the shell 1; the water pan 3 is arranged in the shell 1, and the water pan 3 is positioned between the fan 2 and the air opening; when the air inlet 11 is used as an air inlet, the direction of the air suction opening 21 of the fan 2 is inclined upward relative to the horizontal direction. When wind gap 11 was as the air intake, fan 2 was inhaled gas by wind gap 11, and fan 2 is to keeping away from the direction slope of water collector 3, and inlet scoop 21 induced drafts from the part of keeping away from water collector 3, has avoided water collector 3 to block the air current and influence the air inlet of fan 2, guarantees the amount of wind of fan 2, finally guarantees the heat transfer effect of tuber pipe machine.
Or, when the air inlet 11 is used as an air outlet, the air outlet 22 of the fan 2 is inclined upward with respect to the horizontal direction. When the air outlet 11 is used as an air outlet, the air flow discharged by the fan 2 flows through the air outlet 11 and is blown out, and most of the air flow blown out from the air outlet 22 of the fan 2 flows over the water pan 3 and cannot be blocked by the water pan 3, so that the air quantity of the fan 2 is ensured, and the heat exchange effect of the air pipe machine is finally ensured.
When the air inlet 11 is used as an air inlet, a first inclination angle α is formed between the orientation of the air inlet 21 and the horizontal direction, and the angle range of the first inclination angle α is more than or equal to 0 degree and less than or equal to 12 degrees. Preferably, the first inclination angle α is in the range of 0 ° < α ≦ 12 °.

When the tuyere 11 is used as an air outlet, a second inclination angle beta is formed between the orientation of the air outlet 22 and the horizontal direction, and the angle range of the second inclination angle beta is more than or equal to 0 degree and less than or equal to 15 degrees. Preferably, the second inclination angle β is in the range of 0 ° < β ≦ 15 °.
The simulation test is performed on the mixed flow fan of the embodiment, and the value of the second inclination angle β is changed, wherein the second inclination angle β is inclined upwards relative to the horizontal direction as a positive angle, and the second inclination angle β is inclined downwards relative to the horizontal direction as a negative angle, and the simulation result is as follows:
| angle of rotation | Rotational speed (rpm) | Air volume (m)3/h) | Noise (dB) |
| -2.0 | 2200 | 469 | 48.8 |
| 0.0 | 2200 | 504 | 42.8 |
| 7.2 | 2200 | 526 | 41.3 |
| 15.0 | 2200 | 510 | 42.6 |
| 16.0 | 2200 | 476 | 44.2 |
According to simulation data, when beta is 7.2 degrees, the air volume reaches the maximum value, and the noise reaches the minimum value; when the beta is increased to 15 degrees, the air volume begins to be reduced, and the noise begins to be increased; when beta is continuously increased to 16 degrees, the air quantity attenuation is continuously increased, and the noise is obviously increased; when the beta is reduced to 0 degree, the air volume begins to be reduced, and the noise begins to be increased; when beta is continuously reduced to-2 degrees, the air quantity attenuation is continuously increased, and the noise is obviously increased; the air quantity and noise deviation of the second inclination angle beta in the range of between 0 and beta 15 degrees is not large and the effect is best, and the normal operation of the air duct machine cannot be ensured due to large change after the second inclination angle beta exceeds a critical value.
