S307, air-conditioning set operating condition operation by user.Wherein, when the temperature difference of T1 and T2 is greater than 3, illustrate by current
An indoor fan revolving speed is reduced, coil temperature has dropped very much, reaches desired value, it is ensured that delivery temperature also declines at this time
, compressor protector do not act, and air-conditioning could set operating condition operation according to user.
Meanwhile when the temperature difference of T1 and T2 is less than or equal to 3, step S303 is executed again, is illustrated primary by reducing
Indoor fan revolving speed, coil temperature drop-out value are not up to desired value, it is also necessary to which continuing, which reduces indoor fan revolving speed second, sets shelves
The second preset time t2 is run behind position, until front and back detects that the temperature difference of coil temperature is greater than 3 twice, air-conditioning is set by user
Operating condition operation.Wherein, preferably one grade of gear, the second preset time t2 preferably 20 minutes of the second setting.
Specifically, second specific embodiment according to the present invention, as shown in figure 4, above-mentioned air-conditioning protects control method
The following steps are included:
S401 obtains the working voltage and environment temperature of air-conditioning.
S402, judge frequency air-conditioning this moment whether in setting regions.If so, executing step S409;If not, executing
Step S403.
S403, detection blower fan revolving speed and coil pipe initial temperature T1.
S404 judges whether fixed frequency air conditioner indoor fan revolving speed is zero.If so, executing step S406;If not, executing
Step S405.Wherein, be equipped with inside air-conditioning corresponding judging unit carry out indoor fan revolving speed whether the judgement for being zero,
S406, operation of air conditioner 20 minutes.Wherein, air-conditioning indoor fan revolving speed is that zero explanation is had timed out by reducing revolving speed
Blower does not need to reduce revolving speed again.
S405, indoor fan revolving speed reduce by one grade, operation of air conditioner 20 minutes.
S407 detects coil pipe Current Temperatures T2.
S408, judges whether fixed frequency air conditioner coil pipe initial temperature T1 and the temperature difference of coil pipe Current Temperatures T2 are greater than 3.If
It is to execute step S409;If not, executing step S403.
