Description
Technical field
The present invention relates to a kind of air conditioner technical fields, and in particular to a kind of automatic wind control method of transducer air conditioning.
Background technique
With the continuous improvement of living standards, user proposes increasingly higher demands to the comfort that air conditioner uses.
Wherein the automatic wind mode of transducer air conditioning can automatically adjust wind speed according to environment temperature, and then realize that automatic temperature-adjusting is adjusted.
Such as Chinese invention patent application " a kind of air-conditioning that application publication number is CN104930664A (application No. is 201510363994.8)
The control method and air-conditioning air-conditioning temperature control system of supply air temperature ", disclosed in air-conditioning temperature controlling party
Method passes through the current indoor return air temperature that will test and compares with default supply air temperature, and then is adjusted according to comparing result
Compressor operating frequency reaches control and amendment to supply air temperature.But in the course of work of air conditioner, when windscreen is converted
Afterwards, the variation of indoor heat exchange amount can cause the quick variation in the air conditioner inner coil pipe temperature short time, so by inner coil pipe
The comparison result of temperature and room temperature adjusts carrying out wind speed and easily causes the frequent switching of air conditioner windscreen, room temperature without
Method is stablized, and also causes bad experience to client.
Such as in the case where heating automatic wind mode, if current set temperature is 25 DEG C, environment temperature is 25 DEG C, at this time wind file
With apoplexy stable operation.When set temperature is adjusted to 27 DEG C by 25 DEG C by user, wind file switchs to high wind automatically at this time.And with sky
Room heat supply is assigned, when environment temperature also rises to 27 DEG C, wind file can switch to apoplexy automatically again at this time, because of Gao Fengzhuan apoplexy, air quantity
It is lower, then the indoor heat exchanger heat exchange amount decline of air conditioner, rapid increase in the inner disc temperature meeting short time is gradually fallen after rise flat again
Surely.If inner disc temperature had been approached inner disc high temperature-proof protection frequency reducing value before wind file is converted, with inner disc temperature after the conversion of that wind file
Rapid increase, easily triggering inner disc high temperature-proof protects frequency reducing, and because of the reduction of frequency, environment temperature can decline, at this time wind file
It may be switched to high wind again.So circulation, causes air-conditioning wind file to toggle, room temperature cannot be stablized.
And under automatic wind mode of freezing, if current set temperature is 18 DEG C, environment temperature is 18 DEG C, at this time wind file
With apoplexy stable operation.When set temperature is adjusted to 16 DEG C by 18 DEG C by user, wind file switchs to high wind automatically at this time.And with sky
Room is assigned to freeze, when environment temperature is also down to 16 DEG C, wind file can switch to apoplexy automatically again at this time, because of Gao Fengzhuan apoplexy, air quantity
It is lower, the indoor heat exchanger heat exchange amount of air conditioner declines, and the internal coil of evaporator is (in hereinafter referred to as in air conditioner room unit
Disk) rapid decrease in the temperature meeting short time, then gradually gos up steady again.If it is anti-to have been approached inner disc for inner disc temperature before wind file is converted
Freeze protection frequency reducing value, that wind file conversion after with inner disc temperature decline, easily triggering inner disc anti-freeze protect frequency reducing, and because
The reduction of frequency, environment temperature can rise, and wind file may be switched to high wind again at this time.
