Embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of method for controlling outdoor fan of air-conditioner, reference picture 1, in outdoor fan of air-conditioner controlling party of the present invention In method first embodiment, the method for controlling outdoor fan of air-conditioner includes:
Step S10, when air-conditioning is in the case where heating mode is run, records the temperature value of indoor heat exchanger;
Method for controlling outdoor fan of air-conditioner of the embodiment of the present invention is mainly applied in air-conditioning system, for the fortune to outdoor fan Row state is controlled.Specifically, when air-conditioning is carrying out heating operation, every a preset time segment record once indoor heat exchange The temperature of device.It is understood that the time span of above-mentioned preset time period can be configured according to actual needs;In order to anti- Only the overabundance of data of the temperature value of record indoor heat exchanger, causes internal memory to waste, in the present embodiment, can use the form of array The temperature value of indoor heat exchanger is stored.
Step S20, judges whether the temperature value of the indoor heat exchanger is more than the first preset value;If so, then performing step S30, otherwise terminates;
Step S30, judges whether the speed that indoor heat exchanger temperature rises is more than second according to the temperature value of historical record Preset value;If so, then performing step S30, step S40 is otherwise performed;
Step S40.The rotating speed of outdoor fan is reduced according to the first preset rules;
Step S50, the rotating speed of outdoor fan is adjusted according to the second preset rules.
In the present embodiment, above-mentioned first preset value is the higher limit of high temperature protection, when temperature is higher than first preset value, Into high temperature protection, the size of first preset value can be configured according to actual needs, not limited further herein.
Specifically, judge that the speed that indoor heat exchanger temperature rises can be according to actual need according to the temperature value of historical record It is configured, for example, can be judged according to temperature gap size in preset time period.It is understood that outdoor fan Speed it is bigger, the refrigerant of outdoor heat exchanger heat exchange efficiency is better, so as to cause the refrigerant temperature mistake for being flowed into indoor heat exchanger Height, the final rate of rise in temperature for causing indoor heat exchanger is faster.
Above-mentioned first preset rules can outdoor fan is current according to rotating speed carry out adjustment of rotational speed;For example, adjustment Desired value can subtract current rotating speed the temperature value obtained by one specific value, and rotating speed that can also be current divided by one consolidate Temperature value obtained by definite value.
Above-mentioned second preset rules can carry out rotating speed by the current rotating speed of outdoor fan according to the rotating speed that history is adjusted Adjustment.The rotating speed of outdoor fan can for example be adjusted with the rotating speed before last adjustment according to the current rotating speed of outdoor fan It is whole.
The embodiment of the present invention is by recording the temperature value of indoor heat exchanger, and it is pre- more than first to work as the temperature of indoor heat exchanger If during value, the speed that temperature rises is judged according to the temperature value of historical record.Then according to indoor heat exchanger in different risings In the case of, the rotating speed of outdoor fan is adjusted in different ways.Relative in the prior art, using directly stopping outdoor fan The mode of operation carries out high temperature protection to indoor heat exchanger, when the present invention can effectively prevent air-conditioning heating leaving air temp fluctuation compared with Greatly;Simultaneously without repetitive control outdoor fan start-stop, the service life of outdoor fan is influenceed, so that improve operation of air conditioner can By property.
Once adjusted it is understood that being only described in method for controlling outdoor fan of air-conditioner first embodiment of the present invention Complete scheme, it is necessary to be adjusted repeatedly when actual use, specifically, carry out once adjust after, can be in operation of air conditioner After a period of time, judge whether the temperature value of indoor heat exchanger is more than the first preset value again, if so, then performing step again S30.Only when meeting any one following condition, adjustment is just exited:1st, air-conditioning enters non-heating mode;2nd, indoor heat exchanger Temperature is less than threshold value, is now the initial speed before adjustment by outdoor fan rotating speed;3rd, compressor is out of service.
Further, reference picture 2, based on method for controlling outdoor fan of air-conditioner first embodiment of the present invention, of the invention empty Adjust in outdoor fan control method second embodiment, above-mentioned steps S30 includes:
Step S31, the temperature value that the preset time point before obtaining current time is recorded;
Step S32, judges whether the temperature value obtained is more than the 3rd preset value;If then determining in indoor heat exchanger temperature The speed risen is more than the second preset value, if not, it is determined that the speed that indoor heat exchanger temperature rises is less than or equal to second and preset Value.
In the present embodiment, preset time point before above-mentioned current time can for first 10 seconds of current time it is corresponding when Between point.The size of above-mentioned 3rd preset value can be configured according to actual needs, be made specifically with 1 DEG C in following examples It is bright.If current temperature 45 C, the temperature of first 10 seconds records is 44 DEG C, then both differences are more than 1 DEG C, now determines that interior is changed The temperature that the speed that hot device temperature rises is more than the second preset value, i.e. indoor heat exchanger rises comparatively fast, it is necessary to using above-mentioned first Preset rules enter trip temperature adjustment.
Reference picture 3, based on method for controlling outdoor fan of air-conditioner first embodiment of the present invention, in outdoor fan of air-conditioner of the present invention In control method 3rd embodiment, above-mentioned steps S40 includes:
Step S41, the rotating speed N currently run according to outdoor fansn-1Calculate the rotating speed of target N after adjustmentsn, wherein NsnIt is full Foot:
Step S42, the N obtained according to calculatingsnAdjust the rotating speed of the outdoor fan.
It is understood that in the present embodiment, using the temperature value conduct obtained by current rotating speed divided by a fixed value Target adjustment rotating speed.Specifically, fixed value A is set to 2 in the present embodiment, and other can also be used in other embodiments Value is replaced, i.e., above-mentioned NsnMeet:Subtract it should be noted that can also be used in other real-time modes Method budget, reduction by one is worth during adjustment every time, and the size of the value can immobilize, can also pre-set, every time adjustment pair There should be a value.
