Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure.
In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are a subset of the disclosed embodiments and not all embodiments. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
The air conditioner defrosting control method provided by the disclosure is applied to air conditioner products with heating functions and other scenes for defrosting control of other household appliances capable of heating through refrigeration compression circulation.
With the improvement of living standard of people, the air conditioner becomes an indispensable electrical appliance in the life of people. When the air conditioner is in heating operation in winter, the temperature of the outdoor heat exchanger is lower than the dew point temperature of air, and the air can be condensed on the heat exchanger. When the heat exchanger evaporation temperature is below 0 ℃, the heat exchanger shows frosting. The heat exchanger channel is blocked after frosting, the air inlet resistance is increased, and the heat exchange efficiency of the heat exchanger is reduced. This makes it necessary to periodically defrost the heating process.
In the related art, the defrost cycle is controlled in a temperature-time manner, wherein the time for controlling the defrost cycle is obtained through experience of a technician. In this case, since the system configuration of each type of air conditioner in the market is different, the control time obtained based on experience may cause inaccuracy in the defrosting cycle of the air conditioner control, thereby affecting the comfort level of the user.
In the related art, the defrosting control is performed by calculating the motor attenuation rate of the air conditioner external fan and comparing the motor attenuation rate with a preset threshold value. This approach does not take into account differences in the motors, such as: the motors with the same model may have some differences for different manufacturers, and the motors with the same model and different batches may have some differences. Under the condition, deviation exists between the calculated motor attenuation rate and a preset threshold value, and then the defrosting control accuracy is influenced. In summary, in the related art, the treatment method for accurately starting defrosting aiming at the null withering cannot meet the actual use requirements of users.
In view of this, the present disclosure provides an air conditioner defrosting control method, which can monitor a current value increase rate of an outdoor fan of an air conditioner and determine whether a temperature of an outer tube meets a preset value. The change rule of the current value increase rate of the outdoor fan of the air conditioner is obtained based on the influence of the frost layer growth rule on the fan load. Therefore, the air conditioner can accurately defrost the air conditioner when the defrosting condition meets the preset requirement, and compared with a mode of starting defrosting when the air conditioner is started in the related art, the method can improve the discomfort brought to users by the related art and improve the working efficiency of the air conditioner.
Fig. 1 is a flowchart illustrating an air conditioner defrost control method according to an exemplary embodiment, where the air conditioner defrost control method is used in a terminal, as shown in fig. 1, and includes the following steps.
In step S11, the temperature of the external coil of the air conditioner is monitored.
In the embodiment of the disclosure, when the air conditioner is started in the heating process or after the air conditioner is defrosted, the temperature of the outer coil of the air conditioner is monitored by the indoor pipe temperature sensor. Wherein, when the air conditioner is heating the in-process, indoor pipe temperature sensor can play the effect of anti-cold wind. When the temperature of the outer coil pipe of the air conditioner heat exchanger does not reach a certain high temperature, the indoor fan is controlled not to be started, cold air is prevented from being conveyed to the indoor, and discomfort is brought to a user.
In step S12, when it is determined that the monitored outer coil temperature is less than or equal to the outdoor ambient dew point temperature, the outdoor fan current value is monitored.
Wherein, ItExpressed as an outdoor fan current value.
In step S13, air conditioner defrosting control is performed based on the outdoor fan current value.
In the embodiment of the disclosure, when the evaporation temperature of the heat exchanger is lower than 0 ℃ in the heating process of the air conditioner in winter, the heat exchanger shows that the phenomenon of frosting occurs. Through relevant experimental tests and papers, when water is condensed on the fins of the heat exchanger, the wind resistance of the whole heat exchanger is increased, and the motor of the heat exchanger is increased, so that the current of an outdoor fan is also increased.
According to the method, the temperature of the outer coil of the air conditioner is monitored, when the temperature of the outer coil is determined to be smaller than or equal to the dew point temperature of the outdoor environment, the current value of the outdoor fan is monitored, and defrosting control of the air conditioner is conducted on the basis of the current value of the outdoor fan. The current value of the outdoor fan is monitored, and the current value of the outdoor fan represents the motor rotating speed of the outdoor fan, so that whether the frosting phenomenon occurs on the surface of the heat exchanger of the air conditioner is indirectly explained.
Fig. 2 is a flowchart illustrating an air conditioner defrost control according to an exemplary embodiment, where the air conditioner defrost control is performed based on an outdoor fan current value as shown in fig. 2, and includes the following steps.
In step S21, the rate of increase of current to the outside coil temperature is periodically monitored for a first period of time.
The time period for determining the current increase rate in the disclosed embodiment is referred to as a first time period, which may be, for example, 30s to 60 s.
Where K represents the rate of increase of current in a cycle. K ═ I (I)t+n-It)/ItWherein, ItThe value of the external fan current at time t, It+nThe value of the external fan current at the moment of t + n is a constant value, and the value of n is generally 30-60 s.
In the embodiment of the present disclosure, assuming that the first time length is 45s, that is, the current increase rate of the external coil pipe is monitored every 45s, the current increase rate K (I) calculated and recorded for the first time is (I)45-I0)/I0。
In step S22, if there is a peak value of the current increase rate in the current increase rates periodically monitored for a second continuous period of time, it is determined that the defrosting condition is satisfied, and the air conditioner is controlled to enter the defrosting mode to defrost.
In the embodiment of the disclosure, according to the growth rule of the frost layer of the heat exchanger of the air conditioner, outdoor air is firstly condensed on the fins of the heat exchanger, and the current of the outdoor fan is increased at this stage but the current increase rate is smaller. The condensed water is slowly frozen, the current of the external fan is continuously increased, and the increase rate of the current is gradually increased. As the thickness of the frost layer is increased, the current of the external fan is synchronously increased, and the current growth rate is gradually slowed down. Therefore, in the process of frosting the surface of the air conditioner heat exchanger, the current increase rate of the outdoor fan tends to increase first and then decrease, and therefore, a current increase rate peak value exists in the current increase rate.
According to the defrosting method and device, the current increase rate of the temperature of the outer coil in the first time period is monitored periodically, if the current increase rate peak value exists in the current increase rates monitored periodically for multiple times in the second continuous time period, the condition that defrosting is met is determined, and the air conditioner is controlled to enter a defrosting mode to defrost. The method and the device can judge the degree of frost generation on the surface of the air-conditioning heat exchanger by periodically monitoring whether the current increase rate peak value exists in the current increase rate. When the air conditioner heat exchanger shows that the frosting thickness reaches a certain degree, the defrosting is started, the defrosting is guaranteed to be carried out at the best time, and meanwhile the working efficiency of the air conditioner is improved.
In the disclosure, if there is no peak value of the current increase rate in the current increase rates monitored periodically for a plurality of times in a continuous second time period, the current increase rate of the temperature of the external coil in the first time period is continuously monitored.
Wherein the second duration is generally 10min to 15 min.
In the embodiment of the present disclosure, assuming that the second time period is 12min, the magnitude of the current increase rate of the external coil calculated and recorded every 45s is compared within 12 min. If the current increase rates of the external coil pipes calculated and recorded in each 45s within 12min are approximately the same and equal, it is indicated that no current increase rate peak exists in the current increase rates periodically and repeatedly monitored in the continuous second time period, which indicates that condensation just begins on the fins of the air-conditioning heat exchanger at the moment and the defrosting degree is not reached yet. The embodiment of the disclosure judges the degree of frost generation on the surface of the air conditioner heat exchanger by monitoring whether the current increase rate has a current increase rate peak value. If the defrosting requirement is not met, the air conditioner does not need to start defrosting, and therefore the effect of saving the power consumption of the air conditioner is achieved.
Fig. 3 is a flowchart illustrating an air conditioner defrost control method according to an exemplary embodiment, where the air conditioner defrost control method is used in a terminal, as shown in fig. 3, and includes the following steps.
In step S31, the rate of increase of current to the outside coil temperature is periodically monitored for a first period of time.
In step S32, if there is a peak value of the current increase rate in the current increase rates periodically monitored for multiple times in the second continuous time period, and the current temperature of the external coil is in the temperature range of the external tube for defrosting, and the current temperature of the outdoor environment is in the temperature range of the outdoor environment for defrosting, it is determined that the defrosting condition is satisfied, and the air conditioner is controlled to enter the defrosting mode for defrosting.
In the present disclosure, the outer tube temperature range and the outdoor environment temperature range have a corresponding relationship, and different outer tube temperature ranges correspond to different outdoor environment temperature ranges.
In the disclosure, if it is determined that the current temperature of the external coil is not within the range of the temperature of the external tube for defrosting and/or the current temperature of the outdoor environment is not within the range of the temperature of the outdoor environment for defrosting, the current increase rate of the temperature of the external coil in the first time period is continuously monitored.
In the disclosed embodiment, upon determining that there is a peak in the rate of current increase, the present outside coil temperature and the present outside ambient temperature are determined. And judging whether the air conditioner needs to start defrosting operation or not based on the preset corresponding relation between the current temperature of the outer coil and the current outdoor environment temperature, wherein different outer pipe temperature ranges correspond to different outdoor environment temperature ranges. The correspondence between the outer tube temperature range and the outdoor ambient temperature range is shown in table 1.
TABLE 1
In the embodiment of the disclosure, if the current outdoor environment temperature is-5 ℃ and the temperature of the outer coil is-8 ℃, the temperature of the outer coil does not reach the preset temperature range of the outer coil, the defrosting condition is not met, the air conditioner does not perform defrosting operation, and the current increase rate of the outdoor fan is continuously calculated, recorded and interpreted. And if the current outdoor environment temperature is-10 ℃ and the temperature of the outer coil is-14 ℃, the temperature of the outer coil reaches the preset temperature range of the outer coil, the defrosting condition is met, and the air conditioner performs defrosting operation.
In the present disclosure, the rate of increase of current in the temperature of the external coil is periodically monitored over a first period of time. And if the current increase rate peak exists in the current increase rates periodically monitored for multiple times in the continuous second time period, the current temperature of the outer coil is in the temperature range of the outer pipe for defrosting, and the current temperature of the outdoor environment is in the temperature range of the outdoor environment for defrosting, determining that the defrosting condition is met, and controlling the air conditioner to enter a defrosting mode for defrosting. The increase rate of the current of the external fan acquired by the air conditioner controller is accurate, the defrosting operation is prevented from being started by mistake, and the waste of air drying power is avoided.
Fig. 4 shows a flowchart of an air conditioner defrost control method. As shown in fig. 4, when the air conditioner starts heating operation, in the process of heating the air conditioner, it is determined whether the temperature of the external coil is less than or equal to the dew point temperature of the outdoor environment in real time. If the temperature of the outer coil is less than or equal to the dew point temperature of the outdoor environment, entering a process of acquiring the current value of the outer fan in real time; and if the temperature of the outer coil pipe is greater than the dew point temperature of the outdoor environment, continuously judging the temperature magnitude relation between the temperature of the outer coil pipe and the dew point temperature of the outdoor environment in real time. In the process of acquiring the current value of the external fan in real time, the air conditioner controller calculates and records the current increase rate of the external fan, compares the current increase rates of the external fans in real time in continuous time periods, and judges whether the current increase rate peak value of the external fan exists or not. If the external fan current increase rate has a peak value of the external fan current increase rate, entering a process of judging the temperature of the external coil pipe; and if the current increase rate peak value of the outer fan does not exist in the current increase rate of the outer fan, the air conditioner controller continues to interpret the current increase rate peak value of the outer fan. In the process of judging the temperature of the external coil pipe, when the current outdoor environment temperature is within the range of the preset outdoor environment temperature interval, whether the current temperature of the external coil pipe meets the temperature of the external coil pipe corresponding to the current outdoor environment temperature is judged. If the current temperature of the outer coil pipe meets the temperature of the outer coil pipe corresponding to the current outdoor environment temperature, the condensed water on the surface of the heat exchanger of the air conditioner begins to be slowly frozen, and at the moment, the defrosting condition is reached, and the air conditioner starts defrosting operation; and if the current temperature of the outer coil does not meet the temperature of the outer coil corresponding to the current outdoor environment temperature, the air conditioner controller continues to interpret the current increase rate peak value of the outer fan. By the air conditioner defrosting control method, the air conditioner can automatically recognize through actual running conditions according to the controller, defrosting is started, a large amount of thorough tests are not needed through a development stage, and defrosting starting time is preset. Based on the method, the inaccuracy of the preset time can be avoided, or the inaccuracy of the defrosting starting time caused by the difference between the self-installation environment of the prototype and the actual test environment can be avoided. According to the method, based on the influence of the growth rule of the frost layer and the wind resistance change rule on the motor, the time for the air conditioner to defrost is judged according to actual operation data, the accuracy of defrosting operation of the air conditioner is improved, and therefore the waste of the power consumption of the air conditioner is reduced.
Based on the same conception, the embodiment of the disclosure also provides an air conditioner defrosting control device.
