Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to an air conditioner and a self-cleaning control method thereof.
Background
When the air conditioner operates in a refrigerating or heating mode, air in the external environment enters the machine body along the air inlet, and is blown into the external environment again through the air outlet after the heat exchange of the heat exchange plates, in the process, dust, large particles and other impurities mixed in the air enter the indoor unit along with the air inlet flow, although a dustproof filter screen arranged at the air inlet of the air conditioner can filter most of the dust and the particles, a small amount of tiny dust can not be completely blocked and filtered, and along with long-term use of the air conditioner, the dust can be gradually deposited and attached to the surface of the heat exchange plates, and the heat exchange between the heat exchange plates and the air is directly influenced due to poor heat conductivity of the dust covering the outer surfaces of the heat exchange plates, so that the air conditioner needs to be cleaned regularly in order to ensure the heat exchange efficiency of the air conditioner.
Generally, a cleaning method of an air conditioner in the prior art mainly comprises two modes of manual cleaning and self-cleaning of the air conditioner, wherein the self-cleaning mode of the air conditioner is mainly divided into a frost condensation stage and a defrosting stage, wherein an indoor unit of a split air conditioner is taken as an example, in the frost condensation stage, the air conditioner operates in a refrigeration mode first, and the output of a refrigerant to an indoor heat exchanger is increased, so that moisture in the indoor air can be gradually condensed into frost or an ice layer on the outer surface of the heat exchanger, and the condensed frost layer can be combined with dust in the process, so that the dust is peeled from the outer surface of the heat exchanger; then, in the defrosting stage, the air conditioner operates in a heating mode, so that the frost layer condensed on the outer surface of the heat exchanger is melted, dust is collected into the water receiving disc along with melted water flow, and the aim of self-cleaning the indoor unit of the air conditioner can be achieved; similarly, when the outdoor unit of the split type air conditioner is cleaned, the self-cleaning operation is performed according to a flow opposite to that of the indoor unit, that is, the air conditioner is operated in a heating mode (temperature of the outdoor unit is lowered, frost is condensed) and then in a cooling mode (temperature of the outdoor unit is raised, frost is melted).
In the self-cleaning mode of the air conditioner, the source of the water vapor required for condensing the frost in the frost condensing stage is the water vapor in the air of the external environment where the air conditioner is located, and under certain working conditions (such as winter) or the condition that the water vapor content in the external environment is low, the air conditioner performs the frost condensing stage of the self-cleaning mode according to the set program, so that the actual cleaning effect of the air conditioner is affected.

The method, product and the like disclosed in the examples are relatively simple to describe because they correspond to the method parts disclosed in the examples, and the relevant points are only referred to the description of the method parts.
The air conditioner comprises an indoor heat exchanger, an outdoor heat exchanger, a throttling device and a compressor, wherein the indoor heat exchanger, the outdoor heat exchanger, the throttling device and the compressor are connected through refrigerant pipelines to form a refrigerant circulation loop, and the refrigerant flows along the flow directions set by different operation modes through the refrigerant circulation loop, so that the functions of heating, refrigerating, self-cleaning and the like are realized.
In an embodiment, the operation modes of the air conditioner comprise a refrigeration mode, a heating mode and a self-cleaning mode, wherein the refrigeration mode is generally applied to a high-temperature working condition in summer and is used for reducing the indoor environment temperature; the heating mode is generally applied to a low-temperature working condition in winter and is used for improving the indoor environment temperature; the self-cleaning mode is generally a self-selection function mode or a self-starting function of a user, and can automatically clean the heat exchanger under the condition that more dust and dirt are accumulated on the heat exchanger.
The refrigerant flow direction set in the air conditioner operation refrigeration mode is that the high-temperature refrigerant discharged by the compressor flows through the outdoor heat exchanger to exchange heat with the outdoor environment, then flows into the indoor heat exchanger to exchange heat with the indoor environment, and finally the refrigerant flows back to the compressor to perform compression operation again; in the process, the refrigerant flowing through the outdoor heat exchanger emits heat to the outdoor environment, the refrigerant flowing through the indoor heat exchanger absorbs heat from the indoor environment, and the indoor heat can be continuously discharged to the outdoor environment through the circulating flow of the refrigerant in the refrigerant circulating loop, so that the refrigerating purpose of reducing the indoor environment temperature can be achieved.
The flow direction of the refrigerant set during the heating mode operation means that the high-temperature refrigerant discharged by the compressor firstly flows through the indoor heat exchanger to exchange heat with the outdoor environment, then flows into the outdoor heat exchanger to exchange heat with the indoor environment, and finally the refrigerant flows back to the compressor to perform compression operation again; in the process, the refrigerant flowing through the indoor heat exchanger emits heat to the indoor environment, the refrigerant flowing through the outdoor heat exchanger absorbs heat from the outdoor environment, and the refrigerant can continuously release the outdoor heat to the indoor environment through the circulating flow of the refrigerant in the refrigerant circulating loop, so that the heating purpose of improving the indoor environment temperature can be achieved.
Generally, since the indoor heat exchanger is a heat exchanger directly used for changing the indoor temperature environment, the cleanliness of the indoor heat exchanger can directly affect the use experience of a user. Therefore, the main application object of the self-cleaning mode of the air conditioner is an indoor heat exchanger. Of course, the self-cleaning mode of the air conditioner of the present invention may also be used to clean the outdoor heat exchanger, so in a specific embodiment, when the air conditioner of the present invention performs the cleaning process, only one of the indoor heat exchanger and the outdoor heat exchanger may be cleaned, or both heat exchangers may be cleaned. It should be understood that if the existing air conditioner uses the same or similar control method as the present invention to perform self-cleaning operation on the indoor and outdoor heat exchangers, it should be included in the protection scope of the present invention.
Taking the self-cleaning process of the indoor heat exchanger as an example, the working process of the air conditioner in the self-cleaning mode mainly comprises two stages which are sequentially carried out: and a defrosting stage of the indoor heat exchanger. In the frost stage of the indoor heat exchanger, the indoor heat exchanger of the indoor unit can be frozen and frosted; in the defrosting stage of the indoor heat exchanger, the frost condensed in the previous defrosting stage of the indoor heat exchanger is melted, and impurities such as dust and the like can be separated from the indoor heat exchanger along with the melted condensed water, so that the cleaning treatment of the indoor heat exchanger is completed.
Specifically, in the operation process of the cooling mode, if the power of the compressor is increased, the output of the refrigerant is increased, and the like, the low-temperature refrigerant quantity input into the indoor unit can be increased, the redundant refrigerant quantity can reduce the internal temperature of the indoor unit, and when the internal temperature of the indoor unit is lower than a frost critical temperature value (such as 0 ℃), water vapor in air flowing through the indoor unit can gradually condense into frost in the indoor unit.
In the heating mode operation process of the air conditioner, the high-temperature refrigerant flows through the indoor heat exchanger, so that the cooling capacity of the high-temperature refrigerant can enable the internal temperature of the indoor unit to rise, and when the internal temperature of the indoor unit is higher than a frost condensation critical temperature value (such as 0 ℃), frost condensed in the indoor unit can be gradually melted and dropped, so that the frost can be separated from the indoor heat exchanger. The control method of the invention realizes the defrosting operation of the indoor heat exchanger by adjusting the operation parameters of the compressor, the fan, the throttling device and other parts under the condition that the air conditioner is controlled to flow in the cooling medium defined by the heating mode in the defrosting stage of the indoor heat exchanger.
Similarly, when the self-cleaning operation is performed on the outdoor heat exchanger, the air conditioner flows in the refrigerant flow direction defined by the heating mode, the medium-temperature refrigerant and the high-temperature refrigerant flow out of the indoor heat exchanger, and the low-temperature refrigerant flows into the outdoor heat exchanger after being throttled by the throttling device, so that the low-temperature refrigerant can reduce the temperature of the outdoor heat exchanger, and when the temperature inside the outdoor unit is lower than a frost critical temperature value (such as 0 ℃), water vapor in air flowing through the outdoor unit can be gradually condensed into frost inside the outdoor unit. In this way, the outdoor heat exchanger is frozen and frosted while the indoor heat exchanger is melted and frosted.
And then, the indoor heat exchanger finishes defrosting by melting ice in the defrosting stage of the indoor heat exchanger, the self-cleaning of the indoor heat exchanger is finished, the air conditioner enters the defrosting stage of the outdoor heat exchanger, at the moment, the air conditioner is controlled to flow again in the direction of the refrigerant flow limited by the refrigerating mode, the direction of the high-temperature refrigerant discharged by the compressor is changed, and the high-temperature refrigerant flows through the outdoor heat exchanger first, so that the defrosting by melting ice of the outdoor heat exchanger can be realized by utilizing the heat of the high-temperature refrigerant, and the self-cleaning process of the outdoor heat exchanger is finished.
In the self-cleaning process, each stage can be performed according to a preset time length, for example, the indoor heat exchanger defrosting stage can be preset to be 10 min and the indoor heat exchanger defrosting stage can be preset to be 12 min, so that after the air conditioner enters the indoor heat exchanger defrosting stage in the self-cleaning mode, the air conditioner can start to time, when the air conditioner reaches 10 min, the air conditioner enters the indoor heat exchanger defrosting stage, the indoor heat exchanger defrosting stage lasts for 12 min, the self-cleaning of the indoor machine can be judged to be finished, and the air conditioner exits the self-cleaning mode.
In the process of switching the air conditioner to the flow direction defined by the refrigerating mode or the heating mode, the opening/closing and the rotating speed of the fans of the indoor machine and the outdoor machine also need to be correspondingly controlled, for example, the indoor fan in the frost condensation stage of the indoor heat exchanger is normally closed or runs at a low speed, and the outdoor fan is opened to run; in the defrosting stage of the indoor heat exchanger, the indoor fan is started to operate, and the outdoor fan is closed or operated at a low speed. Therefore, the indoor machine and the outdoor machine are generally respectively timed in the self-cleaning process, and can control the fan and other parts of the air conditioner to perform corresponding state switching when the preset time length is reached.
In the self-cleaning process of the air conditioner, the source of the water vapor required for condensing the frost in the frost condensing stage is the water vapor in the air of the external environment where the air conditioner is located, and under certain working conditions (such as winter) or the condition that the water vapor content in the external environment is low, the air conditioner performs the frost condensing stage of the self-cleaning mode according to the set program, so that the actual cleaning effect of the air conditioner is affected.
Therefore, the invention provides an air conditioner and a self-cleaning control method thereof aiming at the possible problems, and aims to solve the problem of insufficient frost quantity in the self-cleaning frost stage of the air conditioner caused by insufficient humidity.
Fig. 1 is a flowchart illustrating a control method of the air conditioner self-cleaning according to an exemplary embodiment of the present invention.
As shown in fig. 1, the invention provides a control method for self-cleaning of an air conditioner, which mainly comprises the following steps:
s101, responding to a triggering condition meeting a self-cleaning mode, and predicting the frost quantity of a frost flow of the air conditioner in the self-cleaning mode;
optionally, the triggering condition of the self-cleaning mode is that the accumulated running time of the air conditioner reaches a set accumulated time threshold; or the self-cleaning triggering condition is a control instruction which is input by a user and used for starting self-cleaning is received; the present invention is not limited thereto.
In step S101, predicting a frost amount of a condensation flow of the air conditioner in the self-cleaning mode includes: acquiring environmental parameters of the environment where the air conditioner is located and setting parameters of a self-cleaning mode; and determining the frost amount of the air conditioner in the frost flow of the self-cleaning mode based on the environmental parameters and the setting parameters of the self-cleaning mode.
Optionally, environmental parameters include, but are not limited to, indoor temperature and indoor humidity; the set parameters include, but are not limited to, a target frost temperature and a frost length of the frost flow.
Here, before the air conditioner leaves the factory, the final frost amount of the frost flow can be measured in an experiment mode and the like, when the air conditioner is under different environmental conditions (the environmental parameters are different), and the self-cleaning mode is operated with different set parameters; for example, the indoor temperature, the target frost temperature and the frost duration are respectively determined to be 28 ℃, the relative humidity is respectively 40%, 60% and 80% under the humidity conditions, the target frost temperature is A1, the frost duration is B1, the final frost quantity of the frost flow is obtained, in the experimental data, the indoor temperature, the target frost temperature and the frost duration are fixed values, the relative humidity is an independent variable, the final frost quantity is a dependent variable corresponding to the relative humidity, and the frost quantity corresponding to a plurality of different relative humidities in a group of combinations of the indoor temperature, the target frost temperature and the frost duration can be obtained; similarly, through further experiments, the indoor temperature is respectively measured as an independent variable, or the target condensation temperature is used as an independent variable, or the frost duration is used as an independent variable, and the corresponding frost quantity is obtained; and finally summarizing the experimental data to obtain a frost quantity set of a frost flow associated with the acquisition of the environmental parameters of the environment where the air conditioner is located and the setting parameters of the self-cleaning mode.
Here, the invention combines the environmental parameter of the environment where the air conditioner is located and the setting parameter of the self-cleaning mode and the associated frost amount collecting component into a corresponding relation, and pre-stores the corresponding relation in the controller of the air conditioner; in this way, after the trigger condition of the self-cleaning mode is met, the frost amount of the air conditioner in the frost flow of the self-cleaning mode can be determined through the environmental parameter and the setting parameter of the self-cleaning mode.
S102, if the frost quantity does not meet the preset frost quantity requirement, controlling the air conditioner to execute a condensation mode before executing the self-cleaning mode.
In this embodiment, if the amount of frost does not meet the preset frost amount requirement, a problem of poor self-cleaning effect caused by too little frost condensation may occur in the frost flow of the self-cleaning mode, and therefore, the present application controls the air conditioner to perform the condensation mode before performing the self-cleaning mode to increase the amount of condensed water condensed on the heat exchanger to be cleaned, so that the pre-condensed water can be converted into solid frost in the frost stage of the self-cleaning mode, and thus, by performing the condensation mode, the amount of water vapor required for condensation of part of the frost lacking in the frost flow under low humidity conditions can be compensated.
Specifically, the condensation mode executed in the present application may be a dehumidification mode of an existing air conditioner; alternatively, the condensation mode includes: and the working frequency of the compressor of the air conditioner and the flow opening of the throttling device are improved, so that the temperature of the heat exchanger to be cleaned of the air conditioner is reduced from the current temperature to the target condensation temperature.
Here, the air conditioner is also preset with an association relation between the condensation temperature and the indoor humidity of the indoor environment, such as a dew point temperature curve chart, and the like, wherein in the association relation, different indoor humidity corresponds to a determined condensation temperature, and when the temperature is at the condensation temperature associated with the current indoor humidity, water vapor in the air is converted into a liquid state in a gas state; therefore, the obtained indoor humidity can also be used for determining the current condensation temperature according to the association relation and taking the current condensation temperature as the target condensation temperature of the air conditioner executing condensation mode.
Or the target condensation temperature is a fixed temperature value preset by the air conditioner.
Optionally, the control flow of the present invention further includes: and determining the operation duration of the condensation mode based on the determined condensation amount in the step S101 and the preset condensation amount requirement. Here, based on the preset frost amount requirement and the frost amount, a difference in the frost amount may be calculated, and thus, the operation duration of the condensation mode is determined based on the difference in the frost amount. Here, the difference of the frost amount is positively correlated with the operation duration of the condensation mode, i.e., the larger the difference of the frost amount is, the longer the operation duration of the condensation mode is, so as to increase the amount of condensed water condensed in the state of the condensation mode; the smaller the difference in the amount of frost, the shorter the operation duration of the condensation mode.
Optionally, the target condensation temperature may be adjusted according to the determined condensation amount in step S101 and a preset condensation amount requirement. Here, the adjustment of the target condensation temperature is further downward adjustment, i.e., the condensation temperature is continuously reduced; for example, if the correlation between the difference of the preset condensation amount and the temperature adjustment amount of the condensation mode is positive, the larger the difference of the condensation amount is, the larger the temperature amount of the target condensation temperature is adjusted to accelerate the condensation of water vapor on the heat exchanger; when the difference in the amount of frost is small, the amount of temperature at which the target condensation temperature is adjusted downward is smaller.
Here, the lower limit of the down-regulation of the target condensation temperature is a preset frost temperature.
Here, when the air conditioner is operated in the condensation mode for the aforementioned operation period, the air conditioner is controlled to start executing the self-cleaning mode; and (3) the air conditioner re-executes the step of predicting the frost amount in the step S101, and if the frost amount meets the preset frost amount requirement, the air conditioner is controlled to execute a self-cleaning mode.
Here, the specific execution flow of the air conditioner to execute the self-cleaning mode may refer to the foregoing description, and will not be described herein.
Fig. 2 is a second flowchart of a control method for self-cleaning of an air conditioner according to another exemplary embodiment of the present invention.
As shown in fig. 2, the present invention provides a control method for self-cleaning of an air conditioner, which mainly includes the steps of:
s201, responding to the triggering condition meeting the self-cleaning mode, and predicting the frost quantity of the air conditioner in the frost flow of the self-cleaning mode;
in this embodiment, the specific implementation manner of step S201 may refer to step S101, which is not described herein.
S202, if the frost quantity does not meet the preset frost quantity requirement, controlling the air conditioner to execute a condensation mode before executing a self-cleaning mode; the condensation mode comprises controlling and adjusting the operation of at least one component of the air conditioner so as to reduce the temperature of a heat exchanger to be cleaned of the air conditioner from the current temperature to a target condensation temperature, wherein the target condensation temperature is determined according to environmental parameters of the environment in which the air conditioner is positioned.
In this embodiment, if the amount of frost does not meet the preset frost amount requirement, a problem of poor self-cleaning effect caused by too little frost condensation may occur in the frost flow of the self-cleaning mode, and therefore, the present application controls the air conditioner to perform the condensation mode before performing the self-cleaning mode to increase the amount of condensed water condensed on the heat exchanger to be cleaned, so that the pre-condensed water can be converted into solid frost in the frost stage of the self-cleaning mode, and thus, by performing the condensation mode, the amount of water vapor required for condensation of part of the frost lacking in the frost flow under low humidity conditions can be compensated.
Specifically, the condensation mode executed in the present application may be a dehumidification mode of an existing air conditioner; alternatively, the condensation mode includes: and the working frequency of the compressor of the air conditioner and the flow opening of the throttling device are improved, so that the temperature of the heat exchanger to be cleaned of the air conditioner is reduced from the current temperature to the target condensation temperature.
Here, the target condensation temperature is determined according to an environmental parameter of an environment in which the air conditioner is located. The air conditioner is also preset with an association relation between the condensation temperature and the indoor humidity of the indoor environment, such as a dew point temperature curve chart and the like, wherein in the association relation, different indoor humidity corresponds to a determined condensation temperature, and when the temperature is at the condensation temperature associated with the current indoor humidity, water vapor in the air is converted into a liquid state in a gas state; therefore, the obtained indoor humidity can also be used for determining the current condensation temperature according to the association relation and taking the current condensation temperature as the target condensation temperature of the air conditioner executing condensation mode.
Or the target condensation temperature is a fixed temperature value preset by the air conditioner.
Optionally, the control flow of the present invention further includes: and determining the operation duration of the condensation mode based on the determined condensation amount in the step S201 and the preset condensation amount requirement. Here, based on the preset frost amount requirement and the frost amount, a difference in the frost amount may be calculated, and thus, the operation duration of the condensation mode is determined based on the difference in the frost amount. Here, the difference of the frost amount is positively correlated with the operation duration of the condensation mode, i.e., the larger the difference of the frost amount is, the longer the operation duration of the condensation mode is, so as to increase the amount of condensed water condensed in the state of the condensation mode; the smaller the difference in the amount of frost, the shorter the operation duration of the condensation mode.
Optionally, the target condensation temperature may be adjusted according to the determined condensation amount in step S201 and a preset condensation amount requirement. Here, the adjustment of the target condensation temperature is further downward adjustment, i.e., the condensation temperature is continuously reduced; for example, if the correlation between the difference of the preset condensation amount and the temperature adjustment amount of the condensation mode is positive, the larger the difference of the condensation amount is, the larger the temperature amount of the target condensation temperature is adjusted to accelerate the condensation of water vapor on the heat exchanger; when the difference in the amount of frost is small, the amount of temperature at which the target condensation temperature is adjusted downward is smaller.
Here, the lower limit of the down-regulation of the target condensation temperature is a preset frost temperature.
Here, when the air conditioner is operated in the condensation mode for the aforementioned operation period, the air conditioner is controlled to start executing the self-cleaning mode; and the air conditioner re-executes the step of predicting the frost amount in the step S201, and if the frost amount meets the preset frost amount requirement, the air conditioner is controlled to execute the self-cleaning mode.
Here, the specific execution flow of the air conditioner to execute the self-cleaning mode may refer to the foregoing description, and will not be described herein.

Specifically, in this embodiment, the inside humidification device that still is provided with of air conditioner, the inside that the produced steam of humidification device can escape to the indoor set to be the inside steam content increase of indoor set, and then can increase the frost volume that condenses of the frost stage of automatically cleaning mode.

In this embodiment, if the amount of frost does not meet the preset frost amount requirement, a problem of poor self-cleaning effect caused by too little frost condensation may occur in the frost flow of the self-cleaning mode, and therefore, the present application controls the air conditioner to perform the condensation mode before performing the self-cleaning mode to increase the amount of condensed water condensed on the heat exchanger to be cleaned, so that the pre-condensed water can be converted into solid frost in the frost stage of the self-cleaning mode, and thus, by performing the condensation mode, the amount of water vapor required for condensation of part of the frost lacking in the frost flow under low humidity conditions can be compensated.
Specifically, the condensation mode executed in the present application may be a dehumidification mode of an existing air conditioner; alternatively, the condensation mode includes: and the working frequency of the compressor of the air conditioner and the flow opening of the throttling device are improved, so that the temperature of the heat exchanger to be cleaned of the air conditioner is reduced from the current temperature to the target condensation temperature.
Here, the air conditioner is also preset with an association relation between the condensation temperature and the indoor humidity of the indoor environment, such as a dew point temperature curve chart, and the like, wherein in the association relation, different indoor humidity corresponds to a determined condensation temperature, and when the temperature is at the condensation temperature associated with the current indoor humidity, water vapor in the air is converted into a liquid state in a gas state; therefore, the obtained indoor humidity can also be used for determining the current condensation temperature according to the association relation and taking the current condensation temperature as the target condensation temperature of the air conditioner executing condensation mode.
Or the target condensation temperature is a fixed temperature value preset by the air conditioner.
Optionally, the control flow of the present invention further includes: and determining the operation duration of the condensation mode based on the determined condensation amount in the step S401 and a preset condensation amount requirement. Here, based on the preset frost amount requirement and the frost amount, a difference in the frost amount may be calculated, and thus, the operation duration of the condensation mode is determined based on the difference in the frost amount. Here, the difference of the frost amount is positively correlated with the operation duration of the condensation mode, i.e., the larger the difference of the frost amount is, the longer the operation duration of the condensation mode is, so as to increase the amount of condensed water condensed in the state of the condensation mode; the smaller the difference in the amount of frost, the shorter the operation duration of the condensation mode.
Optionally, the target condensation temperature may be adjusted according to the determined condensation amount in step S401 and a preset condensation amount requirement. Here, the adjustment of the target condensation temperature is further downward adjustment, i.e., the condensation temperature is continuously reduced; for example, if the correlation between the difference of the preset condensation amount and the temperature adjustment amount of the condensation mode is positive, the larger the difference of the condensation amount is, the larger the temperature amount of the target condensation temperature is adjusted to accelerate the condensation of water vapor on the heat exchanger; when the difference in the amount of frost is small, the amount of temperature at which the target condensation temperature is adjusted downward is smaller.
Here, the lower limit of the down-regulation of the target condensation temperature is a preset frost temperature.
Here, when the air conditioner is operated in the condensation mode for the aforementioned operation period, the air conditioner is controlled to start executing the self-cleaning mode; and (3) the air conditioner re-executes the step of predicting the frost amount in the step S401, and if the frost amount meets the preset frost amount requirement, the air conditioner is controlled to execute the self-cleaning mode.
Here, in a frost flow of the air conditioner performing the self-cleaning mode, the blower corresponding to the heat exchanger to be cleaned is intermittently turned on and off.
Specifically, the fans are started and stopped at set frequency, for example, in a period with a duration of 10 min, the air conditioner starts the primary fans every 1 min, and the operation duration after each fan start is 5s; optionally, the time interval between two adjacent starts of the fan may be a fixed duration interval or an interval with a non-fixed duration, and the operation duration of a single start of the fan may be equal in length or different in length. Meanwhile, the rotating speeds of the fans after being started can be the same or different. The specific duration and the rotating speed can be set before the air conditioner leaves the factory, so that the fan can realize dynamic running state switching.
The intermittent start and stop of the fan can increase the flow rate of water vapor in the air conditioner in the frost condensation flow, so that frost condensed on the heat exchanger can be more uniform, and the overall cleaning effect is ensured.
