Step S200, measuring chamber inner coil pipe temperature T 2, judgement indoor coil pipe T2 and anti-cold relation of becalming between indoor fan temperature T 2min and target coil pipe temperature T 2aim, and select fan starting pattern according to judged result.
Temperature measuring equipment measuring chamber inner coil pipe temperature T 2, and compare the magnitude relationship between T2, T2min and T2aim, then select fan starting pattern according to comparative result.Be specially:
When T2 < T2min, blower fan does not start;
When T2min≤T2≤T2aim, blower fan starts with Pmin pattern, and this Pmin pattern is the minimum speed pattern that blower fan can allow;
When T2 > T2aim, blower fan starts to set wind pattern, and the air supply pattern that this setting wind pattern is indoor apparatus of air conditioner, can have the some grades of rotating speeds such as high wind shelves, apoplexy shelves, low wind shelves, gentle breeze shelves.
In the present embodiment, for easy computing T2aim and T2min also can directly preset a fixed value, the size of T2aim and T2min is relevant with type.
With reference to Fig. 2, Fig. 2 is the schematic flow sheet of another embodiment of control method of the anti-cold wind of indoor apparatus of air conditioner of the present invention.
The difference of the present embodiment and above-described embodiment is, after step S200, also comprises:
Step S300, monitors and judges whether T2 < T2aim sets up, and if so, according to Δ T2, adjusts the rotating speed of blower fan, wherein, and described Δ T2=T2aim-T2.
Temperature measuring equipment carries out Real-Time Monitoring to T2 and judges whether T2 is less than T2aim, and if so, blower fan enters anti-cold wind mode operation, and under anti-cold wind pattern, blower fan is adjusted its rotating speed according to the size of Δ T2, wherein, and Δ T2=T2aim-T2.
The rotating speed of adjusting blower fan is specially:
When Δ T2 be on the occasion of time, reduce rotation speed of fan;
When Δ T2 is negative value, increase rotation speed of fan;
Wherein, | Δ T2| is larger, and the adjusting range of rotation speed of fan is larger.
Illustrate, as following table 2,
| ΔT2 | -5 | -4 | -3 | -2 | -1 | 0 | 1 | 2 | 3 | 4 | 5 |
| Cycle | 60 | 60 | 60 | 60 | 60 | 60 | 60 | 60 | 60 | 60 | 60 |
| Revolution is adjusted | 90 | 60 | 40 | 30 | 20 | 0 | -20 | -30 | -40 | -60 | -90 |
Table 2
If the setting wind pattern of an indoor apparatus of air conditioner has high, medium and low 3 grades of wind speed, high wind shelves are 1250r/min, and apoplexy shelves are 1100r/min, and low wind shelves are 850r/min, and Pmin is 750r/min.B1＝32，B2＝23。
In the time of T1=10 ℃, user starts shooting with high wind shelves, T2min=16 ℃ now, and T2aim=25 ℃, when T2min16 ℃ of the T2 < measuring, blower fan does not start; In the time of T2 >=T2min16 ℃, blower fan starts with Pmin pattern, with 750r/min entry into service; In the time of T2 >=T2aim25 ℃, blower fan starts to set wind pattern, the high wind shelves 1250r/min running that user selects.
In operation process, when T2 drops to, be less than T2aim, while being less than 25 ℃, blower fan enters anti-cold wind mode operation.Under anti-cold wind pattern, if now record T2=24 ℃, have
ΔT2＝T2aim-T2＝25-24＝1
According to table 2, table look-up, rotation speed of fan needs to reduce for every 60 seconds 20 and turns, if through 240 seconds rotation speed of fan by 1250r/min, be reduced to 1170r/min, now, because rotation speed of fan declines, T2 rises to 25 ℃, blower fan is stabilized in 1170r/min running.
In this process, when T1 rises to 12 ℃, T2min=17 ℃ now, T2aim=26 ℃, has
ΔT2＝T2aim-T2＝26-25＝1
Rotation speed of fan also will reduce by 20 speed that turn with every 60 seconds and continue to reduce, until meet T2=26 ℃, stops reducing rotating speed, maintains current rotation speed operation.| Δ T2| is larger, and the speed that blower fan is adjusted is also larger accordingly, and vice versa, in the hope of adjusting quick and precisely.
When in adjusting the process of revolution, if when rotation speed of fan has reached Pmin, during 750r/min, and T2 < T2aim, make blower fan maintain Pmin mode operation.When T2 < T2min, directly stop blower fan running.
When in the process of adjusting, T2 constantly rises, and rotation speed of fan also adjusts upward accordingly, when adjusting to, sets wind rotating speed, both during high wind 1250r/min, exits anti-cold wind pattern, and indoor apparatus of air conditioner recovers to run well.
In the above-described embodiments, the span of B1 is preferably 20 to 35; The span of B2 is preferably 17 to 28.
In the above-described embodiments, when T2 < T2min being detected, control fan parking.
The control method of the anti-cold wind of indoor apparatus of air conditioner of the present invention makes when indoor apparatus of air conditioner enters anti-cold wind mode operation, the adaptive mild adjusting rotation speed of fan of indoor apparatus of air conditioner meeting, indoor coil pipe T2 is controlled in required value, to guarantee leaving air temp, make air conditioning chamber's inner blower rotating speed can frequent fluctuation.Control accurately, improve heating capacity, guarantee the comfortableness of using.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure transformation that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
