Detailed Description
When the air conditioner is started to operate and heat, the temperature of the indoor heat exchanger needs to be slowly increased. In the beginning of the heating operation of the air conditioner, in order to avoid the discomfort of the user caused by the cold air supply to the user when the air conditioner is started, the cold air prevention mode can be operated at the operation part of the air conditioner, namely, the inner fan is not started at the beginning of the operation of the air conditioner. However, since the air conditioner cannot provide indoor heat through the indoor heat exchanger at the beginning of operation, the air conditioner cannot rapidly and timely raise the indoor ambient temperature, the time of the air conditioner at the beginning of operation is wasted, the indoor ambient temperature cannot be rapidly and timely raised, and the heating efficiency is low.
Therefore, the invention provides a radiation control method of an air conditioner, wherein the air conditioner comprises a radiation heating device, and when an indoor heat exchanger of the air conditioner cannot meet the heating requirement of a user, the indoor heat exchanger can be heated through the radiation heating device, so that the indoor temperature is quickly increased, and the heating requirement of the user is met.
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Referring to fig. 1 to 7, a radiation control method of an air conditioner according to a first aspect of the present invention includes the steps of:
when the air conditioner turns on the radiation heating mode, the indoor ambient temperature T1 is detected. For example, the indoor environment temperature T1 may be detected by a temperature detection mechanism such as a sensor, or the indoor environment temperature T1 may be acquired by an external input (an approximate indoor environment temperature is acquired by a cloud platform, an external temperature detection device, or the like). And judging whether the air conditioner starts a radiation heating function or not according to the indoor environment temperature T1. For example, when the indoor ambient temperature T1 satisfies a predetermined condition, the radiant heating function is turned on; the radiant heating function may be selectively turned off if the indoor ambient temperature T1 does not satisfy the predetermined regulation. Wherein the radiant heating function is adapted to provide heat to the room to increase the indoor ambient temperature T1.
In addition, if the air conditioner starts a radiation heating function, the radiation air deflector, the air conditioner air deflector and the inner fan of the air conditioner are further controlled according to the indoor environment temperature T1. The air conditioner can comprise a radiation heating cavity and a heating assembly, indoor radiation heating is achieved through the radiation heating cavity and the heating assembly, the radiation heating cavity can comprise a ventilation opening and a radiation opening, the heating assembly can radiate heat indoors through the radiation opening, and air can enter the radiation heating cavity through the ventilation opening. In addition, the radiation air deflector can be used for opening and closing the ventilation opening by adjusting the radiation air deflector, and the ventilation quantity of the radiation heating cavity can be adjusted by the radiation air deflector, so that the air flow to the radiation heating cavity is controlled, heat is provided for the indoor space by the radiation heating function, and the purpose of rapid heating is achieved.
According to the radiation control method of the air conditioner, whether the radiation heating function needs to be operated or not can be determined according to the indoor environment temperature T1, and after the radiation heating function is started, the heat distribution of radiation heating and circulating heating can be adjusted through the indoor environment temperature T1, so that the indoor environment temperature T1 is better maintained, and the fluctuation of the indoor environment temperature T1 is reduced.
Specifically, in the present invention, when the heat provided by the indoor circulating heating device (which may be a device including an internal fan, a heat exchanger, etc.) is insufficient, the radiant heating device may be activated, so as to supplement heat to the indoor space through the radiant heating device, thereby avoiding a large fluctuation of the indoor ambient temperature T1 due to the insufficient heat provided by the indoor circulating heating device, and further, improving the performance of the air conditioner. Alternatively, in the present invention, the radiant heating function may be selectively turned on when the indoor ambient temperature T1 is low; and when the indoor heat exchanger cannot meet the indoor heating requirement, the radiation heating function can be selected to be started, for example, a cold air prevention stage when the air conditioner starts to start, a defrosting stage of the air conditioner and the like.
It should be noted that, the heating requirements for different users are different, and therefore, whether to turn on the radiant heating may be determined according to the selection of the user, for example, when the user does not select the radiant heating mode, the radiant heating function may not be turned on regardless of the indoor ambient temperature T1; of course, the radiation heating function may be started when the indoor ambient temperature T1 satisfies a preset condition when the user does not select to cancel the radiation heating mode.
In addition, the radiation control method of the air conditioner according to the embodiment of the present invention may be applied to the air conditioner shown in fig. 4. With reference to fig. 4 to 7, the indoor unit of the air conditioner includes a heat exchange air duct and a radiation heating chamber, wherein the radiation heating chamber has a ventilation opening and a radiation opening, a heating module is disposed in the radiation heating chamber, the heating module is configured to radiate heat from the radiation opening of the radiation heating chamber to the outside of the radiation heating chamber, a radiation air deflector is disposed at the ventilation opening, and the radiation air deflector is used to connect and disconnect the heat exchange air duct and the radiation heating chamber.
Specifically, in conjunction with fig. 4 to 7, the air conditioner may include: a housing 11, an indoor heat exchanger 12, an airflow driver 13 and a heating assembly 14. The indoor heat exchanger 12 can be used to regulate the indoor ambient temperature T1, and the heating assembly 14 can directly heat the indoor space.
Specifically, a heat exchange air duct 101 is arranged in the casing 11, the heat exchange air duct 101 is provided with an air return opening 102 and an air supply opening 103, the indoor heat exchanger 12 is arranged in the heat exchange air duct 101, the air flow driving member 13 is used for driving the air flow to flow from the air return opening 102 to the air supply opening 103, the air flow can return air from the air return opening 102 and enter the heat exchange air duct 101 under the driving action of the air flow driving member 13, and if the air supply opening 103 is in an open state, the air flow can be sent out from the air supply opening 103. The indoor heat exchanger 12 is arranged in the heat exchange air duct 101, and when the air-conditioning room 100 is operated to heat (or refrigerate), the air flow can exchange heat with the indoor heat exchanger 12 when passing through the indoor heat exchanger 12, so that the air flow after heat exchange can be provided through the air supply opening 103, and the purpose of adjusting the indoor environment temperature T1 is achieved.
Additionally, a radiation heating cavity 104 is also provided within the housing 11, the radiation heating cavity 104 having a radiation opening 105, the heating assembly 14 is provided within the radiation heating cavity 104, and the heating assembly 14 is configured and adapted to radiate heat from the radiation opening 105 out of the housing 11. When the heating element 14 is turned on, the heating element 14 may radiate heat to the outside (indoor) of the housing 11 through the radiation port 105, so as to meet the user's demand. Especially, when the heat provided through the heat exchange air duct 101 cannot meet the user's demand, or the indoor heat exchanger 12 is not operated, the heat can be supplemented through the heating assembly 14.
Wherein, the heating assembly 14 in the present invention can be configured to directly radiate heat to the radiation opening 105; it may also be arranged to reflect heat from the heating element 14 towards the radiation opening 105 by reflection from the interior surface of the radiation heating cavity 104; it may also be provided that the interior surface of the radiant heating cavity 104 reflects heat from the heating assembly 14 toward the radiation opening 105 while the heating assembly 14 radiates heat directly toward the radiation opening 105.
The heating assembly 14 of the present invention may be configured as a radiant heating structure, for example, the heating assembly 14 may include a carbon fiber electrical heating tube, a quartz electrical heating tube, etc.
The heating assembly 14 of the present invention can independently heat the indoor, that is, the heating assembly 14 radiates heat to the indoor so as to heat the indoor environment, and at this time, the radiation heating cavity 104 where the heating assembly 14 is located can be completely separated from the heat exchange air duct 101; in addition, the airflow driving part 13 of the heat exchange air duct 101 can drive the airflow to circulate in the radiation heating cavity 104, so that the airflow can exchange heat with the heating component 14, the heat exchange efficiency and effect are improved, and at the moment, the radiation heating cavity 104 and the heat exchange air duct 101 can be communicated with each other; additionally, a separate drive mechanism may be provided to drive the airflow within the radiant heating chamber 104 so that the room temperature can be regulated by the heating assembly 14 alone.
Further, the radiation heating cavity 104 has a vent 106, the vent 106 is provided with a radiation air deflector 15, the radiation air deflector 15 is movable between an open position and a closed position, the radiation air deflector 15 opens the vent 106 in the open position to communicate the radiation heating cavity 104 with the heat exchange air duct 101, and the radiation air deflector 15 closes the vent 106 in the closed position to separate the radiation heating cavity 104 from the heat exchange air duct 101. In the using process, the radiation air deflector 15 can be opened and closed as required, and when the air flow of the heat exchanging air duct 101 needs to be heated through the radiation heating cavity 104 and the heating assembly 14, the radiation air deflector 15 can be opened, so that the air flow of the heat exchanging air duct 101 can be heated through the heating assembly 14 and sent out through the radiation opening 105 after being heated; when the air flow in the heat exchange air duct 101 does not need to be heated through the radiation heating cavity 104 and the heating element 14, the radiation air deflector 15 can be closed, and the air flow in the heat exchange air duct 101 does not pass through the radiation heating cavity 104 any more.
Alternatively, as shown in fig. 1, in the present invention, it may be determined whether the air conditioner starts a radiation heating function according to the indoor ambient temperature T1. The method specifically comprises the following steps:
judging whether the indoor environment temperature T1 is smaller than a first preset temperature threshold Tb or not;
if the indoor environment temperature T1 is smaller than a first preset temperature threshold Tb, controlling the air conditioner to start a radiation heating function;
and if the indoor environment temperature T1 is greater than or equal to a first preset temperature threshold Tb, controlling the air conditioner to close the radiation heating function.
That is to say, when the indoor ambient temperature T1 is at a low value, on the one hand, the shortage of heat supply of the indoor heat exchanger can be compensated by the radiant heating function, and on the other hand, the indoor ambient temperature T1 can be rapidly increased, so that the heating efficiency of the air conditioner can be improved. In addition, during the heating operation of the air conditioner, the indoor ambient temperature T1 is relatively low for some reasons, and at this time, the indoor ambient temperature T1 can be rapidly restored by the radiant heating function, thereby reducing the fluctuation of the indoor ambient temperature T1 and promoting rapid stabilization of the indoor temperature.
In addition, the present invention may determine the on and off of the radiation heating function in other manners, for example, in the radiation heating mode, whether to turn on the radiation heating function is determined according to the difference between the indoor ambient temperature T1 and the set temperature. Specifically, when the difference obtained by subtracting the indoor ambient temperature T1 from the set temperature is large, the radiation heating function is turned on to conveniently and quickly raise the indoor ambient temperature T1 to the set temperature; when the difference is small, the radiation heating function may be turned off to prevent the indoor ambient temperature T1 from increasing too fast to exceed the set temperature. Of course, the on/off of the radiation heating function can be determined in other ways, and the above-mentioned specific selection of the on/off conditions of the radiation heating function is only some specific embodiments of the present invention, and is not intended to limit the scope of the present invention.
In combination with the foregoing embodiments, the radiation air deflector of the present invention may be configured to be rotatable, so as to open and close the ventilation opening by rotation, and to adjust the opening and closing angle of the ventilation opening by rotation. Optionally, the radiation air deflector 15 is configured to be rotatable between an open position and a closed position, and the radiation air deflector 15 is inclined toward the vent 106 relative to the air outlet direction of the heat exchange air duct 101 in the open position. The opening and closing of the radiation air deflector 15 can be realized through rotation, the control of the radiation air deflector 15 is simplified, in addition, when the re-radiation air deflector 15 is opened, the radiation air deflector 15 has a guiding function, and when the air flow of the heat exchange channel passes through the radiation air deflector 15, the air flow flows to the radiation heating cavity 104 under the guiding function of the radiation air deflector 15, so that more air flow can be introduced into the radiation heating cavity 104, and the heating effect of the heating component 14 is improved.
The rotation central axis of the radiation air deflector 15 is adjacent to the downstream side of the vent 106, and in the rotation process of the radiation air deflector 15, when the radiation air deflector 15 is in the open position, the radiation air deflector 15 inclines towards the vent 106 in the air outlet direction of the heat exchange channel, the rotation central axis and the end edge of the radiation air deflector 15 are spaced by a preset distance, and the downstream side of the vent 106 can be provided with a groove, so that in the rotation process of the radiation air deflector 15, the groove can give way to the radiation air deflector 15, so that the radiation air deflector 15 can smoothly rotate, wherein the inner surface of the groove can be set into an arc shape matched with the shape of the radiation air deflector 15, so that the relative sealing between the radiation air deflector 15 and the groove can be conveniently realized, and the flow guiding effect of the radiation air deflector 15 on airflow is improved.
Alternatively, in combination with the foregoing embodiment, the radiation wind deflector 15 is provided in a rotatable form, and the ventilation opening can be opened and closed by rotation, and the opening degree of the ventilation opening can be adjusted by rotation. And when the air conditioner starts a radiation heating function, controlling a radiation air deflector, an air conditioner air deflector and an inner fan of the air conditioner according to the indoor environment temperature T1. As shown in fig. 2, the method specifically includes the following steps:
and judging the indoor environment temperature T1, and determining different operation states of the radiation heating function according to different indoor environment temperatures T1. The method specifically comprises the following steps:
if the indoor environment temperature T1 is greater than a second preset temperature threshold Ta and less than a first preset temperature threshold Tb, controlling the radiation air deflector to open at a second angle, and controlling the air conditioner air deflector to open at a first angle;
that is to say, when the indoor ambient temperature T1 is relatively high (the indoor ambient temperature T1 is greater than the second preset temperature threshold Ta and less than the first preset temperature threshold Tb), at this time, the indoor heat exchanger can provide appropriate heat for the room, but the heat provided by the indoor heat exchanger cannot provide rapid increase of the indoor ambient temperature T1, at this time, in order to achieve rapid increase of the indoor ambient temperature T1, the radiation heating function and the internal circulation heating function can be simultaneously started, wherein the fan is turned on to cause the indoor air to flow back into the air conditioner, so that the air flow can exchange heat with the indoor heat exchanger, the air conditioner air deflector 16 is opened to cause the air flow to be sent out through the main air outlet of the air conditioner, so that heating of the room is achieved, the radiation air deflector is opened, the air flow can enter the radiation heating cavity to exchange heat with the heating assembly, so as to carry more heat to the room, through the combination of indoor heat exchanger and heating element, can heat indoor air fast, realize promoting fast indoor ambient temperature T1, moreover, for example the air current circulation heating ground mode, when improving heating efficiency, can also guarantee the homogeneity of heat promotion ground, impel the heat to send to the bigger scope.
And if the indoor environment temperature T1 is less than a second preset temperature threshold Ta, controlling the radiation air deflector to be in a closed state, controlling the air conditioner air deflector to be in a closed state, and controlling the inner fan to be in a closed state, wherein the second preset temperature threshold Ta is less than a first preset temperature threshold Tb.
That is to say, when the indoor ambient temperature T1 is low, the indoor heat exchanger cannot provide appropriate heat for the indoor space, for example, the air conditioner is in a cold air prevention state when being turned on, and the outdoor unit is in a defrosting process, and at this time, the indoor heat exchanger is insufficient to provide indoor heat, the inner fan is in a closed state at this time, and the radiation air deflector and the air conditioner air deflector are both closed, at this time, the radiation heating function is turned on, that is, the heating element is turned on, and at this time, the heating element radiates heat outwards in a radiation heating manner, so as to quickly raise the indoor ambient temperature T1.
As the indoor heat exchanger increases in temperature, after a period of time, the indoor heat exchanger may initially provide more heat to the room for an increase in the indoor ambient temperature T1. Therefore, in the state that the indoor environment temperature T1 is less than the second preset temperature threshold Ta, the radiation air deflector and the air conditioner air deflector are both closed, and the fan is stopped, after the first preset time, the radiation air deflector is controlled to be opened by the second angle, and the air conditioner air deflector is controlled to be opened by the first angle. Thereby, more uniform and faster temperature increase can be provided indoors through the air flow, the increasing speed of the indoor ambient temperature T1 is effectively increased, and simultaneously, faster and more stable indoor ambient temperature T1 is promoted.
Alternatively, the first preset time of the present invention may be in the range of 30 seconds to 5 minutes, for example, the first preset time is set to 1 minute.
In addition, in the foregoing adjusting process, whether the indoor ambient temperature T1 is less than the second preset temperature threshold Ta and the radiation heating function is operated for the first preset time, or the indoor ambient temperature T1 is greater than the second preset temperature threshold Ta and is less than the first preset temperature threshold Tb, the rotation speed of the inner fan may be adjusted according to a difference between the indoor ambient temperature T1 and the second preset temperature threshold Ta.
For example, when the indoor ambient temperature T1 is greater than the second preset temperature threshold Ta and less than the first preset temperature threshold Tb, the inner fan rotation speed may be set to: n (T1-Ta) (ζ + 1). And xi is a correction coefficient, wherein xi can be valued according to the temperature of the indoor heat exchanger and the type of the air conditioner, the value range is 0-1, n can be a preset rotating speed, for example, n can be a preset percentage of the rated rotating speed of the internal fan, and the preset percentage can be in the range of 10-80%.
For another example, after a first preset time after the indoor ambient temperature T1 is less than the second preset temperature threshold Ta, the rotation speed of the inner fan may be set to n (Ta-T1) × (ζ + 1).
Optionally, in an operation process that the air conditioner starts a radiation heating function, if the indoor environment temperature T1 is greater than the first preset temperature threshold Tb, the air conditioner is controlled to stop the radiation heating function, the rotating speed of the inner fan is adjusted according to a difference value between the indoor environment temperature T1 and the first preset temperature threshold Tb, and the radiation air deflector is controlled to be closed, the air conditioner air deflector is controlled to be closed, and the inner fan is controlled to be closed until a second preset time.
That is, when the indoor ambient temperature T1 is less than the first preset temperature threshold Tb, the radiation heating function is turned on, the indoor ambient temperature T1 gradually increases with the heating of the air conditioner, and when the indoor ambient temperature T1 increases to be greater than the first preset temperature threshold Tb, the radiation heating function may be turned off, and at this time, the rotation speed of the internal fan may be adjusted according to the difference between the indoor ambient temperature T1 and the first preset temperature threshold Tb, for example, the rotation speed of the internal fan is adjusted to n (T1-Tb) × (ζ + 1).
And as the temperature is continuously increased (for example, after the second preset time elapses), the indoor environment temperature T1 has reached a suitable temperature, and at this time, the internal fan may be turned off, so as to achieve energy saving and environmental protection.
Among them, the second preset time in the present invention may be set to be in the range of 0 to 5 minutes, for example, the second preset time is set to be 30 seconds.
In summary, according to the radiation control method of the air conditioner of the embodiment of the invention, the radiation air deflector, the air conditioner air deflector and the inner fan of the air conditioner are controlled according to the temperature of the indoor heat exchanger, so that the indoor temperature can be rapidly adjusted, the severe fluctuation of the indoor temperature is prevented, and the heating comfort is improved.

Especially, when the heat provided through the heat exchange air duct 101 cannot meet the user's demand, or the indoor heat exchanger 12 is not operated, the heat can be supplemented through the heating assembly 14.

Fig. 8 is a block diagram illustrating a radiation control device 200 of an air conditioner according to an embodiment of the present invention.
The radiation control device 200 of the air conditioner according to the fourth aspect of the present invention includes: a first temperature detection module 201 and a control module 202.
The first temperature detection module 201 is used for detecting an indoor environment temperature T1; the control module 202 is configured to determine whether the air conditioner starts the radiation heating function according to the indoor environment temperature T1 when the air conditioner starts the radiation heating mode, and further control the radiation air deflector, the air conditioner air deflector, and the internal fan of the air conditioner according to the indoor environment temperature T1 when the air conditioner starts the radiation heating function.
It should be noted that the radiation control device 200 of the air conditioner according to the embodiment of the present invention can be applied to the air conditioner shown in fig. 4, specifically, as shown in fig. 4, the air conditioner indoor unit 100 includes a heat exchange air duct 101 and a radiation heating cavity 104, wherein the radiation heating cavity 104 has a ventilation opening 106 and a radiation opening 105, a heating assembly 14 is disposed in the radiation heating cavity 104, the heating assembly 14 is configured to radiate heat from the radiation opening 105 of the radiation heating cavity to the outside of the radiation heating cavity, a radiation air deflector 15 is disposed at the ventilation opening 106, and the radiation air deflector 15 is used to turn on and off the heat exchange air duct 101 and the radiation heating cavity 104.
According to the radiation control device 200 of the air conditioner of the embodiment of the present invention, it can be determined whether the radiation heating function needs to be operated according to the indoor ambient temperature T1, and after the radiation heating function is turned on, the heat distribution of the radiation heating and the circulation heating can be adjusted by the indoor ambient temperature T1, so that the indoor ambient temperature T1 can be better maintained to reduce the fluctuation of the indoor ambient temperature T1.
Specifically, whether the heat exchange air in the heat exchange air duct 101 needs to pass through the heating assembly 14 can be controlled by the radiation air deflector 15, and it can be understood that the heating assembly 14 can be a heating structure of a radiation electric heating tube.
Optionally, when determining whether the air conditioner starts the radiation heating function according to the indoor environment temperature T1, the control module 202 is further configured to determine whether the indoor environment temperature T1 is less than a first preset temperature threshold Tb; if the indoor environment temperature T1 is less than a first preset temperature threshold Tb, controlling the air conditioner to start a radiation heating function; and if the indoor environment temperature T1 is greater than or equal to the first preset temperature threshold Tb, controlling the air conditioner to close the radiation heating function. That is to say, when the indoor ambient temperature T1 is at a low value, on the one hand, the shortage of heat supply of the indoor heat exchanger can be compensated by the radiant heating function, and on the other hand, the indoor ambient temperature T1 can be rapidly increased, so that the heating efficiency of the air conditioner can be improved. In addition, during the heating operation of the air conditioner, the indoor ambient temperature T1 is relatively low for some reasons, and at this time, the indoor ambient temperature T1 can be rapidly restored by the radiant heating function, thereby reducing the fluctuation of the indoor ambient temperature T1 and promoting rapid stabilization of the indoor temperature.
Optionally, the control module 202 is further configured to determine an indoor environment temperature T1 when controlling the radiation air deflector, the air conditioner air deflector, and the internal fan of the air conditioner according to the indoor environment temperature T1; if the indoor environment temperature T1 is greater than a second preset temperature threshold Ta and less than a first preset temperature threshold Tb, controlling the radiation air deflector to open a second angle, controlling the air conditioner air deflector to open a first angle, and adjusting the rotating speed of the inner fan according to the difference between the indoor environment temperature T1 and the second preset temperature threshold Ta; and if the indoor environment temperature T1 is less than a second preset temperature threshold Ta, controlling the radiation air deflector to be in a closed state, controlling the air conditioner air deflector to be in a closed state, controlling the inner fan to be in a closed state, controlling the radiation air deflector to be opened at a second angle after first preset time, controlling the air conditioner air deflector to be opened at a first angle, and adjusting the rotating speed of the inner fan according to the difference between the second preset temperature threshold Ta and the indoor environment temperature T1.
That is to say, when the indoor ambient temperature T1 is relatively high (the indoor ambient temperature T1 is greater than the second preset temperature threshold Ta and less than the first preset temperature threshold Tb), at this time, the indoor heat exchanger can provide appropriate heat for the room, but the heat provided by the indoor heat exchanger cannot provide rapid increase of the indoor ambient temperature T1, at this time, in order to achieve rapid increase of the indoor ambient temperature T1, the radiation heating function and the internal circulation heating function can be simultaneously started, wherein the fan is turned on to cause the indoor air to flow back into the air conditioner, so that the air flow can exchange heat with the indoor heat exchanger, the air conditioner air deflector is opened to cause the air flow to be sent out through the main air outlet of the air conditioner, so that the indoor heating is achieved, the radiation air deflector is opened, the air flow can enter the radiation heating cavity to exchange heat with the heating assembly, so as to carry more heat to the room, through the combination of indoor heat exchanger and heating element, can heat indoor air fast, realize promoting fast indoor ambient temperature T1, moreover, for example the air current circulation heating ground mode, when improving heating efficiency, can also guarantee the homogeneity of heat promotion ground, impel the heat to send to the bigger scope.
When the indoor environment temperature T1 is low, the indoor heat exchanger cannot provide appropriate heat for the room, for example, the air conditioner is in a cold air prevention state when being turned on, and the outdoor unit defrosting process, and at this time, the indoor heat exchanger is insufficient to provide indoor heat, the internal fan is in a closed state at this time, and the radiation air deflector and the air conditioner air deflector are both closed, at this time, the radiation heating function is turned on, that is, the heating assembly is turned on, and at this time, the heating assembly radiates heat outwards through a radiation heating mode, so that the indoor environment temperature T1 is rapidly increased.
As the indoor heat exchanger increases in temperature, after a period of time, the indoor heat exchanger may initially provide more heat to the room for an increase in the indoor ambient temperature T1. Therefore, in the state that the indoor environment temperature T1 is less than the second preset temperature threshold Ta, the radiation air deflector and the air conditioner air deflector are both closed, and the fan is stopped, after the first preset time, the radiation air deflector is controlled to be opened by the second angle, and the air conditioner air deflector is controlled to be opened by the first angle. Thereby, more uniform and faster temperature increase can be provided indoors through the air flow, the increasing speed of the indoor ambient temperature T1 is effectively increased, and simultaneously, faster and more stable indoor ambient temperature T1 is promoted.
Alternatively, the first preset time of the present invention may be in the range of 30 seconds to 5 minutes, for example, the first preset time is set to 1 minute.
In addition, in the foregoing adjusting process, whether the indoor ambient temperature T1 is less than the second preset temperature threshold Ta and the radiation heating function is operated for the first preset time, or the indoor ambient temperature T1 is greater than the second preset temperature threshold Ta and is less than the first preset temperature threshold Tb, the rotation speed of the inner fan may be adjusted according to a difference between the indoor ambient temperature T1 and the second preset temperature threshold Ta.
For example, when the indoor ambient temperature T1 is greater than the second preset temperature threshold Ta and less than the first preset temperature threshold Tb, the inner fan rotation speed may be set to: n (T1-Ta) (ζ + 1). And xi is a correction coefficient, wherein xi can be valued according to the temperature of the indoor heat exchanger and the type of the air conditioner, the value range is 0-1, n can be a preset rotating speed, for example, n can be a preset percentage of the rated rotating speed of the internal fan, and the preset percentage can be in the range of 10-80%.
For another example, after a first preset time after the indoor ambient temperature T1 is less than the second preset temperature threshold Ta, the rotation speed of the inner fan may be set to n (Ta-T1) × (ζ + 1).
Optionally, the control module 202 is further configured to, in an operation process of the air conditioner in which the radiation heating function is turned on, control the air conditioner to turn off the radiation heating function if the indoor ambient temperature T1 is greater than the first preset temperature threshold Tb, and adjust the rotation speed of the inner fan according to a difference between the indoor ambient temperature T1 and the first preset temperature threshold Tb, until a second preset time, control the radiation air deflector to turn off, control the air conditioner air deflector to turn off, and control the inner fan to turn off.
That is, when the indoor ambient temperature T1 is less than the first preset temperature threshold Tb, the radiation heating function is turned on, the indoor ambient temperature T1 gradually increases with the heating of the air conditioner, and when the indoor ambient temperature T1 increases to be greater than the first preset temperature threshold Tb, the radiation heating function may be turned off, and at this time, the rotation speed of the internal fan may be adjusted according to the difference between the indoor ambient temperature T1 and the first preset temperature threshold Tb, for example, the rotation speed of the internal fan is adjusted to n (T1-Tb) × (ζ + 1).
And as the temperature is continuously increased (for example, after the second preset time elapses), the indoor environment temperature T1 has reached a suitable temperature, and at this time, the internal fan may be turned off, so as to achieve energy saving and environmental protection.
Among them, the second preset time in the present invention may be set to be in the range of 0 to 5 minutes, for example, the second preset time is set to be 30 seconds.
