When air-conditioner is started shooting under dehumidification mode, acquiescence runs high wind shelves, detects the temperature T1 and relative humidity RH at return air inlet place after the t1 time, then reads the dew point temperature TL of correspondence from presetting database；Then the coil temperature T2 of vaporizer (indoor heat exchanger) is detected, and coil temperature T2 is made comparisons with dew point temperature TL, if T2≤TL-N DEG C, keeping currently running wind shelves, wherein, N can select between 3～10 DEG C, when in meeting the following conditions arbitrary time, the wind shelves of air-conditioner are lowered one grade, until being lowered to minimum wind shelves:
1、T2>TL-N℃；
2, the t2 time is run.
Additionally, air-conditioner is in dehumidification process, monitor the relative humidity RH at return air inlet place in real time, when RH terminates less than or equal to dehumidifying when setting humidity.Handling process as shown in Figure 4, including:
Step 402, air-conditioner is started shooting with dehumidification mode, and runs with high wind shelves.
Step 404, the temperature T1 and relative humidity RH at detection return air inlet place, and determine dew point temperature TL.
Step 406, it is judged that coil temperature T2, whether more than TL-N, if so, then performs step 410；Otherwise, step 408 is performed.
Step 408, it is judged that the duration t that air-conditioner runs with current wind shelves, whether more than t2, if so, then performs step 410；Otherwise, step 406 is returned.
Step 410, it is judged that whether the current wind shelves of air-conditioner are minimum wind shelves, if so, then performs step 414；Otherwise, step 412 is performed.
Step 412, wind shelves lower one grade, and return step 404.
Step 414, maintains current wind shelves and terminates to dehumidifying.
Three wind shelves are had to be described in detail for the indoor fan of constant speed air-conditioning below:

1, t1=1min；
2, t2 arranges also difference according to the different of RH: during 1. RH > 90%, t2=90min；2. 70% < during RH≤90%, t2=60min；3. during RH≤70%, t2=30min；
3, N value takes 3.
When dehumidification mode opened by air-conditioner, indoor fan acquiescence opens high wind shelves, after 1 minute, detect that T1 temperature is 20 DEG C, RH is 95%, and then passing through parameter preset inquiry dew point temperature TL now is 18.4 DEG C, if detecting, now T2 temperature is 14 DEG C, due to 14 DEG C of < 18.4-3 DEG C, therefore continue to run with high wind shelves；
After monitoring 20 minutes in real time, T1 is 18 DEG C, and RH is 80%, and now dew point temperature TL is 14.58 DEG C, if detecting, T2 is 12 DEG C, due to 12 DEG C > 14.58-3 DEG C, then wind shelves are lowered one grade and are run apoplexy shelves；
After assuming 60min, relative humidity RH is more than 70%, and T2≤TL-N DEG C, then wind shelves transfer low wind shelves, continuous service to, until user's shutdown or relative humidity RH reach setting value, such as 50%.
Above-described embodiment is only one embodiment of the present invention, and parameter therein can be set according to different types and operating area.
Wherein, detecting T1 and RH after arranging the t1 time in the above embodiment of the present invention again is in order to avoid when air-conditioner is just started shooting, T2 value is unstable and cause the problem that frequently switches wind shelves；The purpose arranging N DEG C is to allow have individual difference between T2 and dew point temperature, is conducive to the condensation of steam；Arranging t2 when being to prevent the humidity sensor detection error at return air inlet place, air-conditioning runs high wind shelves always and causes the halfway problem that dehumidifies.
Technical scheme is described in detail above in association with accompanying drawing, the present invention proposes the dehumidifying scheme of a kind of new air-conditioner, rapid moisture removal can be realized, solve the problem that air-conditioner in prior art causes when dehumidifying with low wind shelves that room air circulation is smooth, dehumidifying time length, effect on moisture extraction are poor.
