The invention provides a control method for defrosting of an air conditioner, wherein the air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling air conditioner and the like.
As shown in fig. 1, the control method for defrosting of an air conditioner includes the following steps:
step S110: and acquiring frost point temperature, environmental parameters and set temperature.
After the air conditioner starts the operation mode of heating, the air conditioner acquires the set temperature that the user set up to acquire environmental parameter and frost point temperature through the sensor, environmental parameter includes: ambient temperature, ambient humidity, and the area or volume of the space in which the air conditioner is located.
In the process of acquiring the frost point temperature, because the relative humidity below zero is difficult to obtain, the relative humidity can only be inquired in a humidity lookup table below the freezing point, the environment is divided into regions, the environment temperature has the corresponding wet bulb temperature so as to obtain the relative humidity U, and the frost point temperature t is calculated by using the formula (1)fThe formula is as follows:
wherein t is the ambient temperature in degrees centigrade; u is relative humidity.
Step S120: and adjusting the running state of the air conditioner based on the frost point temperature, the set temperature and the environmental parameters.
After the frost point temperature, the set temperature and the environmental parameters are determined, the working state of the air conditioner is adjusted, the working states of a compressor and an indoor fan in the air conditioner are controlled on the premise of ensuring the load requirement, the compressor and the indoor fan are ensured to operate in a stable state as far as possible, cold and hot alternation is avoided, and the temperature of the air conditioner during operation is higher than the frost point temperature as far as possible.
Step S130: and judging whether the current running state of the air conditioner meets the anti-frosting requirement of the air conditioner by adjusting the rotating speed of the outdoor fan.
Step S140: and if the air conditioner can not meet the anti-frosting requirement, controlling the air conditioner to operate above the frost point temperature.
After the working state of the air conditioner is controlled, the air conditioner detects the temperature of the coil pipe through the sensor, the current running state of the air conditioner is judged, and whether the anti-frosting requirement of the air conditioner can be met by adjusting the outdoor fan or not is judged.
If the frost prevention requirement cannot be met by adjusting the rotating speed of the outdoor fan, the working frequency of a compressor in the air conditioner is adjusted, so that the temperature of the coil pipe is higher than the frost point temperature. That is, if the outdoor fan cannot be adjusted to make the coil temperature > the frost point temperature, the operating frequency of the compressor in the air conditioner is adjusted, and the coil temperature > the frost point temperature is generally controlled to be lowered.
And if the air conditioner can meet the anti-frosting requirement by adjusting the rotating speed of the outdoor fan, controlling the air conditioner to keep the current running state. That is, if the outdoor fan is adjusted to meet the requirement that the temperature of the coil pipe is higher than the frost point temperature, the air conditioner keeps the current heating state to operate without adjusting the working frequency of the compressor.
The control method for defrosting the air conditioner comprises the steps of firstly obtaining frost point temperature, environmental parameters and set temperature, then adjusting the running state of the air conditioner based on the frost point temperature, the set temperature and the environmental parameters to enable the temperature of the air conditioner during running to be higher than the frost point temperature as much as possible, finally judging the current running state of the air conditioner, judging whether the outdoor fan can meet the anti-frosting requirement of the air conditioner or not, and controlling the air conditioner to run above the frost point temperature under the condition that the air conditioner cannot meet the anti-frosting requirement, so that the influence of defrosting on normal running of the air conditioner is avoided, and user experience is improved.
On the basis of the above embodiment, as shown in fig. 2, step S140: if the air conditioner can not meet the anti-frosting requirement, the step of controlling the air conditioner to operate above the frost point temperature comprises the following steps:
step S150: the temperature difference between the coil temperature and the frost point temperature is determined.
If the anti-frosting requirement cannot be met by adjusting the rotating speed of the outdoor fan, after the working frequency of the compressor is controlled, in order to avoid frosting of the air conditioner in the process that the anti-frosting requirement cannot be met, the air conditioner determines the temperature of the coil pipe through the sensor, and determines the temperature difference between the temperature of the coil pipe and the temperature of a frost point.
Step S160: and adjusting the rotating speed of the outdoor fan based on the temperature difference between the coil pipe temperature and the frost point temperature.
After the temperature difference between the coil pipe temperature and the frost point temperature is determined, the rotating speed of the outdoor fan is adjusted based on the temperature difference between the coil pipe temperature and the frost point temperature.
Under the condition that the temperature difference between the coil pipe temperature and the frost point temperature is within a first preset range, the rotating speed of the outdoor fan is controlled to be kept unchanged as the coil pipe temperature is closer to the frost point temperature. For example, when the temperature difference between the coil temperature and the frost point temperature is 0 ℃ to 3 ℃, the rotating speed of the outdoor fan is controlled to be kept unchanged in order to avoid frosting due to the lower coil temperature. If the temperature difference between the coil pipe temperature and the frost point temperature is less than 0 ℃, the rotating speed of the outdoor fan can be reduced to avoid frosting.
Under the condition that the temperature difference between the coil pipe temperature and the frost point temperature is in a second preset range, the rotating speed of the outdoor fan is controlled to be increased due to the fact that the temperature difference between the coil pipe temperature and the frost point temperature is large and the coil pipe temperature is high; and the temperature difference value in the second preset range is larger than the temperature difference value in the first preset range. For example, when the temperature difference between the coil temperature and the frost point temperature is above 3 ℃, the rotating speed of the outdoor fan can be controlled to be increased in order to improve the efficiency of the air conditioner.
If the air conditioner can meet the anti-frosting requirement by adjusting the rotating speed of the outdoor fan, the outdoor fan can be further adjusted in the control process in order to further avoid frosting in the process. For example, when the temperature difference between the coil temperature and the frost point temperature is 0 ℃ to 3 ℃, the rotating speed of the outdoor fan is controlled to be constant or reduced to avoid frosting due to the lower coil temperature. If the temperature difference between the coil pipe temperature and the frost point temperature is less than 0 ℃, the rotating speed of the outdoor fan can be reduced to avoid frosting. When the temperature difference between the coil pipe temperature and the frost point temperature is more than 3 ℃, the rotating speed of the outdoor fan can be controlled to be increased in order to improve the efficiency of the air conditioner.
On the basis of the above embodiment, as shown in fig. 3, step S120: the step of adjusting the operating state of the air conditioner based on the frost point temperature, the set temperature and the environmental parameter includes:
step S310: and determining the required heat according to the set temperature and the environmental parameters.
In order to control the working state of the air conditioner, the required heat quantity Q is determined by using the formula (2) according to the acquired set temperature and the environmental parameter1. Since the environmental parameters include: ambient temperature, ambient humidity, and the area or volume of the space in which the air conditioner is located.
Q1＝CAir (a)×M1×△t1 (2)
Wherein, CAir (a)Is the specific heat capacity of air, M1For indoor air quality,. DELTA.t1Is the difference between the ambient temperature and the set temperature.
Step S320: based on the heat, a plurality of sets of target temperatures and target air volumes are determined.
At the determined heat quantity Q1And (4) determining the relation between the target temperature and the target air volume by using the formula (3).
Q1＝CAir (a)×VAir quantityρAir (a)×(tEnvironment(s)-tTarget) (3)
And determining multiple groups of target temperatures and target air volumes by utilizing the relation between the target temperatures and the target air volumes, wherein each target temperature corresponds to one target air volume.
Step S330: if at least one group of target temperature is higher than the frost point temperature, the working frequency of the compressor is adjusted based on the target temperature higher than the frost point temperature, and the rotating speed of the indoor fan is adjusted based on the corresponding target air volume.
If at least one group of target temperatures are higher than the frost point temperature, the air conditioner can avoid frosting according to adjustment, the working frequency of a compressor in the air conditioner is adjusted based on one target temperature higher than the frost point temperature, the compressor and an indoor fan are ensured to operate in a stable state as far as possible, cold and hot alternation is avoided, the temperature of the air conditioner during operation is always higher than the frost point temperature, and the rotating speed of the indoor fan in the air conditioner is adjusted based on the corresponding target air volume.
If all the target temperatures are less than or equal to the frost point temperature, the air conditioner cannot guarantee to avoid frosting, the working frequency of a compressor in the air conditioner is adjusted based on any one of the target temperatures, the air conditioner can also work in a default mode, and the rotating speed of an indoor fan in the air conditioner is adjusted based on the corresponding target air volume.
