Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
In the embodiment of the disclosure, in the air conditioner self-cleaning defrosting process, the operation frequency of the air conditioner compressor can be controlled according to the temperature of the coil of the evaporator, wherein when the temperature of the coil is lower, the operation frequency of the compressor is increased to increase the temperature of the coil, and when the temperature of the coil is higher, the operation frequency of the compressor is reduced to reduce the temperature of the coil, so that the temperature of the evaporator is always higher in the heating process, thus, ice or water on the evaporator can be vaporized and evaporated to a greater extent, the humidity in an air conditioner action area is increased, and the humidity loss caused by self-cleaning frosting is compensated, thereby reducing the harm to human bodies or property caused by low humidity.
Fig. 1 is a schematic flow chart of an air conditioner self-cleaning control method in an embodiment of the present disclosure. As shown in fig. 1, the process of the air conditioner self-cleaning control may include:
step 101: and under the condition that the current self-cleaning operation of the air conditioner is determined to be in a defrosting and heating operation state, acquiring the current time length of the heating operation of the air conditioner in the current self-cleaning operation.
In the embodiment of the present disclosure, the air conditioner self-cleaning process is a process of first condensing and increasing humidity, and then frosting and then defrosting the surface of the evaporator, and specifically may include: firstly, controlling the frequency of a compressor and an electronic expansion valve to reduce the temperature of an evaporator to be below the dew point temperature, and controlling a fan to continuously bring moisture in the air to the surface of the evaporator for condensation; then, adjusting at least one device such as the frequency of a compressor and an electronic expansion valve to reduce the surface temperature of the evaporator, and simultaneously closing a fan to quickly frost the surface of the evaporator; and finally, reversing a four-way valve of the air conditioner, controlling the heating operation of the compressor, quickly defrosting and flushing the evaporator by using water, thereby realizing a primary self-cleaning process. Therefore, the self-cleaning operation of the air conditioner can be influenced by the time, the frosting temperature, the fan speed, the compressor frequency, the opening degree of the electronic expansion valve and other parameters corresponding to the three stages of condensation, frosting and defrosting.
The self-cleaning operation of the air conditioner is performed through three stages of condensation, frosting and defrosting. Each stage is to achieve condensation, frosting or defrosting effects by controlling at least one device of the air conditioner within a corresponding time, wherein the device comprises: an electronic expansion valve, a fan, a compressor, or an air deflector. In the embodiment of the disclosure, the control process of the device is not limited in the condensation and frosting processes of the air conditioner, and a specific strategy is provided for controlling the corresponding device in the defrosting process.
After the condensation and frosting stages, the air conditioner is switched from a cooling operation mode to a heating operation mode, and at the moment, the four-way valve of the air conditioner is reversed. In some embodiments, the operation state of the air conditioner is determined according to the conduction direction of the four-way valve, that is, the current self-cleaning operation of the air conditioner is determined to be in a defrosting and heating operation state according to the conduction direction of the four-way valve. Of course, once the four-way valve is reversed, the air conditioner enters the initial state of the heating operation, and the timing of the air conditioner heating operation needs to be carried out.
Therefore, as long as the self-cleaning operation of the air conditioner is in a defrosting and heating operation state, the heating operation duration of the air conditioner in the self-cleaning operation can be sampled in real time or at regular time, and the current duration of the current self-cleaning operation hollow modulation heating operation can be obtained.
Step 102: and under the condition that the current time length is less than the set defrosting time length, acquiring the current coil temperature of the evaporator.
Each stage of the self-cleaning operation of the air conditioner generally has a preset time length, wherein the time length corresponding to the defrosting stage is the set defrosting time length. Therefore, the acquired current time length is less than the set defrosting time length, which can indicate that the air conditioner is in a defrosting and heating operation state, and at the moment, the current coil temperature of the evaporator can be acquired. As long as the current time length obtained by each sampling is less than the set defrosting time length, the corresponding current coil temperature can be obtained.
In some embodiments, the current coil temperature of the evaporator may be obtained by a temperature sensor disposed on the evaporator coil.
Step 103: and controlling the running frequency of the air-conditioning compressor according to the current coil temperature.
In the self-cleaning operation process of the air conditioner, condensation water or frost generated in the condensation and frosting stages all come from water vapor in an air conditioning action area, and in order to make up for the loss of the water vapor, the temperature of the evaporator is required to be always at a higher temperature in the defrosting stage, so that the ice or water on the evaporator can be vaporized and evaporated to a greater extent.
In some embodiments, controlling the operating frequency of the air conditioner compressor comprises: under the condition that the current coil temperature is less than or equal to a first set temperature, controlling the running frequency of the air-conditioning compressor to rise at a first set speed; controlling the running frequency of the air conditioner compressor to be reduced at a second set speed under the condition that the current coil temperature is greater than or equal to a second set temperature; wherein the first set temperature is less than the second set temperature. It can be seen that, when the coil pipe temperature that acquires is lower at every turn, the operating frequency that can increase the compressor gradually makes the coil pipe temperature rise, and when the coil pipe temperature was higher, the operating frequency that can reduce the compressor gradually makes the coil pipe temperature descend, and when the coil pipe temperature was between first settlement temperature and second settlement temperature, the operating frequency that can maintain the compressor was unchangeable, thus, can maintain the evaporimeter temperature in the maximum and be in higher temperature, thereby, ice or water on the evaporimeter can be gasified evaporation in the great degree, the humidity in the air conditioning effect region has been increased, reduce the harm of the person or property that brings because of humidity is low.
The first set temperature and the second set temperature can be determined according to air conditioner hardware information, air conditioner environment information and the like. The specific configuration can be realized through parameter input, or the determination can be realized through calculation according to the acquired environment hardware parameters and the like.
It can be seen that, in this embodiment, in the air conditioner self-cleaning defrosting process, the operating frequency of the air conditioner compressor can be controlled according to the temperature of the coil pipe of the evaporator, wherein when the temperature of the coil pipe is lower, the operating frequency of the compressor is increased to raise the temperature of the coil pipe, and when the temperature of the coil pipe is higher, the operating frequency of the compressor is reduced to lower the temperature of the coil pipe, thereby the temperature of the evaporator in the heating process can be always higher, so that ice or water on the evaporator can be vaporized and evaporated to a greater extent, the humidity in the air conditioner action area is increased, the humidity loss caused by self-cleaning defrosting is compensated, and therefore, the harm to the human body or property caused by low humidity is reduced.
Certainly, in the defrosting stage of the air conditioner, in order to further accelerate the evaporation process of ice or water on the evaporator, the fan and the air deflector can be adjusted after the defrosting stage is started. In some embodiments, after determining that the current self-cleaning operation of the air conditioner is in the defrosting and heating operation state, the rotation speed of the fan may be adjusted to a first rotation speed, and the air deflector of the air conditioner is controlled to be at the maximum air outlet position.
Hardware equipment in the air conditioner is not completely the same, and under the condition that the air conditioner is provided with the electric auxiliary heating device, the electric auxiliary heating device in the air conditioner can be started after the current self-cleaning operation of the air conditioner is determined to be in a defrosting and heating operation state.
Or after the current self-cleaning operation of the air conditioner is determined to be in a defrosting and heating operation state, only adjusting the rotating speed of the fan to the first rotating speed; or the rotating speed of the fan is adjusted to the first rotating speed, and an air deflector of the air conditioner is controlled to be in the maximum air outlet position; or only turning on the electric auxiliary heating device in the air conditioner; or the rotating speed of the fan is adjusted to the first rotating speed, and the electric auxiliary heating device in the air conditioner is started; or, the rotating speed of the fan is adjusted to the first rotating speed, the air deflector of the air conditioner is controlled to be located at the maximum air outlet position, and the electric auxiliary heating device in the air conditioner is also started.
Therefore, by controlling one, two or more devices in the fan, the air deflector, the electric auxiliary heating device and the like, the gasification and evaporation process of ice or water on the evaporator can be accelerated, the probability of humidity loss is further reduced, and the harm to human bodies or property caused by low humidity is reduced.
The defrosting stage of the air conditioner corresponds to the set defrosting time length, so that when the current time length is greater than or equal to the set defrosting time length, the self-cleaning process is finished, the air conditioner can perform self-cleaning again and can run a mode matched with the environmental parameters, for example: cooling mode, heating mode, sleep mode, etc. Since the self-cleaning process is finished, the time length corresponding to the self-cleaning process does not need to be accumulated any more, and the saved current time length needs to be cleared. Therefore, the next self-cleaning process can be smoothly carried out.
The following operation flows are integrated into a specific embodiment to illustrate the air conditioner self-cleaning control process provided by the embodiment of the present invention.
In one embodiment of the present disclosure, a set defrosting time period d, a first set temperature a, a second set temperature b, a first set rate khz/s, and a second set rate mhz/s are configured.

step 201: is the conduction direction of the four-way valve in the current self-cleaning operation determined to be consistent with the heating operation direction? If yes, go to step 202, otherwise, go back to step 201.
Of course, the timing of the heating operation can be performed as soon as the four-way valve is reversed in the self-cleaning operation of the air conditioner. In this step, it is determined whether the four-way valve is in the defrosting and heating operation state according to the conduction direction of the four-way valve? If yes, go to step 202.
Step 202: and adjusting the rotating speed of the fan to c revolutions per second, and controlling an air deflector of the air conditioner to be at the maximum air outlet position.
Of course, if the air conditioner is configured with an electric auxiliary heating device, the electric auxiliary heating device can be turned on in this step.
Step 203: and acquiring the current time length of the current self-cleaning operation hollow modulation thermal operation.
Step 204: determine whether the current time period t is less than the set defrosting time period d? If so, go to step 205, otherwise, go to step 211.
Step 205: the current coil temperature Tp of the evaporator is obtained.
Step 206: is it determined whether the current coil temperature Tp is less than or equal to the first set temperature a? If yes, go to step 207, otherwise, go to step 208.
Step 207: and controlling the running frequency of the air-conditioning compressor to rise at the first set speed khz/s, and returning to the step 203.
Step 208: is the current coil temperature Tp determined to be greater than or equal to the second set temperature b? If so, go to step 209, otherwise, go to step 210.
Step 209: and controlling the running frequency of the air conditioner compressor to drop at a second set speed mhz/s, and returning to the step 203.
Step 210: and controlling the running frequency of the air conditioner compressor to be kept unchanged, and returning to the step 203.
Step 211: and carrying out zero clearing treatment on the stored current time length, and finishing the self-cleaning process.
Therefore, in the embodiment, in the self-cleaning defrosting stage, the temperature of the coil of the evaporator can be obtained in real time, and the operating frequency of the air-conditioning compressor is controlled according to the temperature of the coil of the evaporator, so that the temperature of the evaporator is always at a higher temperature in the heating process, ice or water on the evaporator can be vaporized and evaporated to a greater extent, the humidity in an air-conditioning action area is increased, and the harm of humidity reduction caused by self-cleaning frosting is reduced. In addition, one, two or more devices in the fan, the air deflector, the electric auxiliary heating device and the like are controlled, so that the gasification and evaporation process of ice or water on the evaporator can be accelerated, the probability of humidity loss is further reduced, and the harm to human bodies or property caused by low humidity is further reduced.
