Abstract
The invention relates to a method for controlling a dust removal device of a heat exchanger of an outdoor machine of an air conditioner. The dust removal device comprises a fan and control equipment, wherein the control equipment comprises a timer, a receiver, a judger and an actuator; and the control equipment controls the fan to reversely rotate for dust removal. The method is characterized by comprising the following steps that: when the air conditioner normally operates, the receiver continuously receives operating parameter information which is fed back by the air conditioner and transmits the operating parameter information to the judger; the judger judges the operating parameter information; when the judger determines that the operating parameter information meets a preset dust removal mode operating condition, the air conditioner operates for dust removal; the actuator controls a compressor of the air conditioner to stop operating; the timer clears the accumulated operating time of the air conditioner and the continuous operating time of the compressor; the actuator controls the fan to stop, the timer starts timing, and when time is equal to first time T1, the judger determines that the fan is in a static state; the actuator controls the fan to start and rotate in the opposite direction relative to the normal operation direction; the timer re-starts timing, and when the time is equal to second time T2, the actuator controls the fan to stop; the timer re-starts timing, and when the time is equal to third time T3, the judger determines that the fan is in the static state; and the air conditioner quits a dust removal mode, starts to normally operate or is directly powered off. By the method, the normal operation of the air conditioner is not influenced, the air conditioner can automatically remove dust, and the service life of the air conditioner can be prolonged.
Description
Technical field
The present invention relates to the dedusting technology of air-conditioner outdoor unit heat exchanger in the field of air conditioning, specifically is a kind of control method of dust arrester of air-conditioner outdoor unit heat exchanger.
Background technology
Detachable air conditioner utilizes the fan of its off-premises station to be reversed to the dedusting of off-premises station heat exchanger, can reduce the laying dust of off-premises station heat exchanger, reduce air-conditioner ability attenuation rate, drain on manpower and material resources when reducing artificial dedusting in addition, even can avoid the potential safety hazard of work high above the ground.But, many use fan counter-rotatings are carried out dedusting to air-conditioner, because can not fully, thoroughly consider the practical operation situation of air-conditioner, the fan counter-rotating dedusting control method of designing is unreasonable, the problem that occurs has: opening, stopping of the counter-rotating of fan and compressor is too frequent, even fan is just being changeed do not stop as yet just reversing suddenly, not only influenced the normal operation of air-conditioner, do not satisfy user's demand, and can shorten the service life of fan and compressor; The off-premises station of air-conditioner is not enough because of the dedusting number of times, and fan counter-rotating dust collection capacity descends, and makes laying dust form dirt because the gathering time is long.
Summary of the invention
The object of the invention is to endeavour to address the above problem, and normally uses for dust arrester provides a kind of air-conditioning that neither influences, again dedusting and can prolong air-conditioner service life automatically
OnePlant the control method of the dust arrester of air-conditioner outdoor unit heat exchanger.
In order to achieve the above object, technical scheme of the present invention is: a kind of control method of dust arrester of air-conditioner outdoor unit heat exchanger, dust arrester comprises fan, control appliance, control appliance comprises timer, receiver, determining device and actuator, control appliance control fan counter-rotating dedusting is characterized in that this control method may further comprise the steps:
When 1) air-conditioner normally moved, the receiver of control appliance constantly received the trip information of air-conditioner feedback and is transferred to the determining device of control appliance, and determining device is judged this trip information;
2) determine described trip information when satisfying the dedusting mode operation condition preset when determining device, air-conditioning enters the dedusting operation: the compressor of the actuator control air-conditioner of control appliance is out of service, and the timer of control appliance is with time and the compressor time zero clearing of operation continuously of the operation of air-conditioner accumulative total; Simultaneously, the actuator control fan of control appliance stops, and timer picks up counting, after timing reaches very first time T1, determining device judges that fan is inactive state, then actuator controls that fan is opened and opposite direction rotation during with normal operation again, and timer restarts timing simultaneously, after timing reaches second time T 2, actuator is controlled fan again and is stopped, timer restarts timing simultaneously, and after timing reached the 3rd time T 3, determining device judged that fan is inactive state;
3) air-conditioner withdraws from the normal operation of dedusting pattern recovery or directly shutdown.
The described satisfied dedusting mode operation condition that presets is: the cumulative time that the timer of control appliance calculates the normal operation of air-conditioner reaches the scheduled time, and compressor is reaching certain time when time continuous operating time.
The described satisfied dedusting mode operation condition that presets is: the temperature that is conditioned the zone reaches preset temperature value, and air-conditioner outdoor unit is shut down, and compressor is reaching certain time when time continuous operating time.
The described satisfied dedusting mode operation condition that presets is: the user carries out power-off operation to air-conditioner.
The present invention's advantage compared with prior art is: utilize the original fan of air-conditioner outdoor unit that its heat exchanger is carried out dedusting, need not to increase other structure, tangible cost advantage is arranged.In addition, control method of the present invention does not influence normal the use substantially of air-conditioning, can avoid that the frequent dedusting of air-conditioner or dedusting number of times are very few to cause the fouling of heat exchanger surface laying dust, effectively solution makes off-premises station blower fan and high frequent stop, rotate problems such as not stopping counter-rotating suddenly at once, makes obtain prolonging the service life of air-conditioner.
