Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.
An air conditioner and a control method and apparatus thereof according to an embodiment of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of an air conditioner according to an embodiment of the present application. The air conditioner comprises a fresh air channel, wherein the fresh air channel is provided with a fresh air switch door, the fresh air channel is communicated with an internal circulation air channel, and the internal circulation air channel is provided with an internal circulation switch door.
As shown in fig. 1, the control method of the air conditioner according to the embodiment of the application includes the following steps:
s101: the first temperature of the fresh air duct and the dew point temperature of the fresh air duct are respectively obtained.
The first temperature comprises at least one of an air inlet temperature and an air return temperature, different first temperatures correspond to different dew point temperatures, namely the air inlet temperature corresponds to the air inlet dew point temperature, and the air return temperature corresponds to the air return dew point temperature. The air inlet temperature is the fresh air temperature of the fresh air duct, and the return air temperature is the temperature outside the fresh air duct.
S102: and identifying the condensation state of the fresh air duct according to the first temperature and the dew point temperature.
Specifically, if the first temperature is identified to be smaller than or equal to the corresponding dew point temperature, the fact that condensation occurs in the fresh air duct is determined, or if the first temperature is identified to be larger than the corresponding dew point temperature, the fact that condensation does not occur in the fresh air duct is determined.
It should be understood that condensation is the effect of the moisture in the air that encounters cold and liquefies, so when the first temperature of the fresh air duct is less than or equal to the condensation temperature, the first temperature of the fresh air duct will liquefy and condense into water drops on the wall of the fresh air duct, thereby causing the condensation of the fresh air duct, further causing the temperature of the fresh air to be reduced and affecting the energy efficiency of the air conditioner.
Specifically, when the intake air temperature is less than or equal to the intake air dew point temperature, i.e., the temperature inside the fresh air duct is less than or equal to the dew point temperature, condensation occurs inside the fresh air duct, and when the return air temperature is less than or equal to the return air dew point temperature, i.e., the temperature outside the fresh air duct is less than or equal to the dew point temperature, condensation occurs outside the fresh air duct.
S103: and controlling the fresh air switch door and the internal circulation switch door according to the condensation state.
Further, according to the condensation state, controlling the fresh air switch door and the internal circulation switch door includes: the method comprises the steps of identifying that condensation occurs in a fresh air duct, controlling a fresh air switch door to be closed, and opening an inner circulation switch door, or identifying that condensation does not occur in the fresh air duct, controlling the fresh air switch door to be opened, and controlling the inner circulation switch door to be closed.
That is, when the fresh air duct is exposed (including the inner side and the outer side of the fresh air duct), the fresh air switch door needs to be controlled to be closed so as to prevent the fresh air duct from continuing to be exposed, the working efficiency of the air conditioner is affected, the inner circulation switch door is opened so as to maintain the air conditioner to continue to operate through the inner circulation duct, when the fresh air duct is not exposed, the fresh air switch door is controlled to be opened (the open state is maintained when the fresh air switch door is opened, and the fresh air switch door is controlled to be opened when the fresh air switch door is closed), and the inner circulation switch door is controlled to be closed so as to maintain the air conditioner to operate through the fresh air duct, thereby meeting the fresh air requirement of a user.
According to the different designs of the air conditioner, the fresh air switch door and the internal circulation switch door can be two independent controllable switch doors, and the opening and closing of the fresh air switch door and the opening and closing of the internal circulation switch door are required to be controlled respectively, or the fresh air switch door and the internal circulation switch door are the same switch door, that is, the internal circulation switch door is necessarily closed when the fresh air switch door is controlled to be opened, and the internal circulation switch door is necessarily opened when the fresh air switch door is controlled to be closed. Therefore, no matter what setting mode is adopted by the fresh air switch door and the internal circulation switch door, the fresh air switch door and the internal circulation switch door are not opened at the same time.
According to one embodiment of the application, the first temperature of the fresh air duct and the dew point temperature of the fresh air duct are respectively obtained, and the method comprises the following steps: and identifying the operation mode of the air conditioner as a refrigeration mode or a dehumidification mode, determining the air inlet temperature as a first temperature, acquiring the dew point temperature corresponding to the air inlet temperature according to the air inlet temperature and the first relative humidity of the fresh air duct, identifying the operation mode as a heating mode, determining the air return temperature as the first temperature, and acquiring the dew point temperature corresponding to the air return temperature according to the air return temperature and the second relative humidity of the fresh air duct.
When the operation mode of the air conditioner is the cooling mode or the dehumidifying mode, the indoor temperature is reduced by the cooling of the air conditioner, that is, the indoor temperature is lower than the outdoor ambient temperature, and the external temperature of the fresh air duct is lower than the internal temperature of the fresh air duct, so that condensation is easily generated inside the fresh air duct. Therefore, when the air conditioner is in refrigeration or dehumidification operation, the dew point temperature corresponding to the air inlet temperature is obtained according to the air inlet temperature (namely the outdoor temperature) and the first relative humidity of the fresh air channel, so that the condensation inside the fresh air channel is determined when the air inlet temperature is lower than the dew point temperature.
Similarly, when the operation mode of the air conditioner is the heating mode, the indoor temperature is increased due to heating of the air conditioner, that is, the outdoor temperature is lower than the indoor environment temperature, and the internal temperature of the fresh air duct is lower than the external temperature of the fresh air duct, so that condensation is easily generated outside the fresh air duct. Therefore, when the air conditioner heats and operates, the dew point temperature corresponding to the return air temperature is obtained according to the return air temperature (namely the indoor temperature) and the first relative humidity of the fresh air duct, so that the outside condensation of the fresh air duct is determined when the return air temperature is lower than the dew point temperature.
It should be noted that, the present application only reflects the main sources of the air temperature inside and outside the fresh air duct through the indoor temperature and the outdoor temperature, and preferably, temperature sensors can be arranged on the inner wall and the outer wall of the fresh air duct to detect the temperature of the inner wall of the fresh air duct so as to judge whether the inner wall and/or the outer wall of the fresh air duct are condensed or not. Specifically, the temperature of other communication positions can be adopted to replace the temperature sensor arranged on the inner wall or the outer wall of the fresh air duct, and the detailed description is omitted.
It should be understood that during cooling or dehumidifying operation of the air conditioner, the first relative humidity for calculating the dew point temperature is the relative humidity of the outdoor air because dew occurs inside the fresh air duct, and during heating operation of the air conditioner, the second relative humidity for calculating the dew point temperature is the relative humidity of the indoor air because dew occurs outside the fresh air duct. Wherein the relative humidity is detectable by a humidity sensor.
Further, material information of the fresh air duct is identified, a compensation coefficient of the dew point temperature is obtained according to the material information, and the obtained dew point temperature is compensated according to the compensation coefficient.
It should be noted that, since the fresh air duct is condensed according to the temperature difference between the inner side and the outer side, heat loss is generated no matter the temperature of the outer side is transferred to the inner side or the temperature of the inner side is transferred to the outer side, and therefore, the temperature loss needs to be compensated according to the material information to determine the actual dew point temperature of the inner side/the outer side of the fresh air duct.
Further, the control method of the air conditioner further comprises the following steps: the control fan keeps running, namely, after the fresh air switch door and the internal circulation switch door are controlled, the control fan also keeps running so as to continuously supply air to the inside of the air conditioner, and the heat exchange requirement of the indoor heat exchanger is ensured.
It should be noted that, since the fresh air duct is communicated with the internal circulation duct, only one fan may be disposed at the communicating position, and it should also be understood that the fresh air duct fan and the internal circulation duct fan may be disposed at the non-communicating position, respectively, so that the fan needs to be controlled to be opened or closed simultaneously with the corresponding switch door, that is, when the fresh air switch door is controlled to be opened, the fan in the fresh air duct is controlled to be opened, and when the internal circulation switch door is controlled to be opened, the fan in the internal circulation duct is controlled to be opened.
Still further, before the first temperature of the fresh air duct and the dew point temperature of the fresh air duct are respectively obtained, the method further comprises: and receiving a control instruction for opening the fresh air, and opening the fresh air fan and the fresh air switch door according to the control instruction.
That is, in the foregoing control method of the air conditioner, when a control instruction for opening the fresh air is received, that is, when the user selects the fresh air function, the fresh air fan and the fresh air switch door are opened according to the control instruction at this time, so as to ensure the fresh air requirement of the user, and then, whether to close the fresh air switch door is determined according to the condensation state of the fresh air duct, so as to ensure the working efficiency of the air conditioner.
In summary, the control method of the air conditioner provided by the embodiment of the application can control the fresh air switch door and the internal circulation switch door according to the condensation condition of the fresh air channel, and improve the energy efficiency of the air conditioner under the condition of ensuring the fresh air requirement of a user.
