DETAILED DESCRIPTION

The embodiments of the present disclosure will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings, throughout which same or similar elements, or elements having same or similar functions, are denoted by same or similar reference numerals. The embodiments described below with reference to the drawings are illustrative only, and are intended to explain, rather than limiting, the present disclosure.
A control method for a mobile air conditioner, a mobile air conditioner, a computer-readable storage medium, and a control apparatus of a mobile air conditioner provided by the embodiments of the present disclosure are described below with reference to the drawings.
FIG. 1 is a flowchart of a control method for a mobile air conditioner according to an embodiment of the present disclosure.
Referring to FIG. 1, the control method for the mobile air conditioner according to the embodiments of the present disclosure may include the following blocks.
At block S1, an indoor ambient temperature and an outdoor ambient temperature are obtained.
At block S2, an indoor ambient-temperature change value △T1, an outdoor ambient-temperature change value △T4, and an indoor-outdoor temperature difference △T are determined based on the indoor ambient temperature and the outdoor ambient temperature.
At block S3, a type of an air duct of the mobile air conditioner is determined based on the indoor ambient-temperature change value △T1, the outdoor ambient-temperature change value △T4, and the indoor-outdoor temperature difference △T, and an operating limit parameter of the mobile air conditioner is determined based on the type of the air duct.
At block S4, the mobile air conditioner is controlled based on the operating limit parameter.
In some embodiments, when the mobile air conditioner is powered on and started, and when a compressor starts operating, an initial indoor ambient temperature T10 and an initial outdoor ambient temperature T40 are respectively obtained through corresponding temperature sensors. After the mobile air conditioner is controlled to operate for predetermined time t1, a current indoor ambient temperature T11 and a current outdoor ambient temperature T41 are obtained again through the temperature sensors. An indoor ambient-temperature change value △T1=|T11-T10|, an outdoor ambient-temperature change value △T4=|T41-T40|, and a current indoor-outdoor temperature difference △T=|T41-T11| are calculated. Then, it is determined whether a type of an air duct currently installed in the mobile air conditioner is a dual air duct or a single air duct based on the indoor ambient-temperature change value △T1, the outdoor ambient-temperature change value △T4, and the current indoor-outdoor temperature difference △T. Then, the operating limit parameter is determined based on the type of the air duct installed in the mobile air conditioner. Moreover, the mobile air conditioner is controlled to operate under the operating limit parameter. Therefore, in this method, whether the mobile air conditioner is installed with the dual air duct or the single air duct is determined by detecting change situations in the indoor ambient temperature and the outdoor ambient temperature of the mobile air conditioner during operation of the mobile air conditioner. After the type of the air duct installed in the mobile air conditioner is determined, the mobile air conditioner is controlled to operate based on the corresponding operating limit parameter. In this way, targeted control optimization is performed based on the type of the air duct of the mobile air conditioner, which ensures exertion of overall performance of the mobile air conditioner to the maximum extent and improves user experience.
It should be noted that each of calculation formulas for the indoor ambient-temperature change value △T1, the outdoor ambient-temperature change value △T4, and the current indoor-outdoor temperature difference △T in the above-mentioned embodiments adopts a calculation manner of an absolute value. Except for the above-mentioned calculation manners, the indoor ambient-temperature change value △T1, the outdoor ambient-temperature change value △T4, and the current indoor-outdoor temperature difference △T may also be calculated based on an operation mode of the air conditioner. For example, when it is determined that the air conditioner operates in a cooling mode, the indoor ambient-temperature change value is △T1=T10-T11, the outdoor ambient-temperature change value is △T4=T40-T41, and the current indoor-outdoor temperature difference is ΔT=T41-T11. When the air conditioner operates in a heating mode, the indoor ambient-temperature change value is △T1=T11-T10, the outdoor ambient-temperature change value is △T4=T41-T40, and the current indoor-outdoor temperature difference is △T=T11-T41.
In addition, it should be noted that the above-mentioned indoor ambient temperature is a temperature of an environment where the mobile air conditioner is currently located, and may be obtained through a temperature sensor disposed at an outer shell of the mobile air conditioner. The outdoor ambient temperature is an ambient temperature of air sucked by an external air passage of the mobile air conditioner. In an embodiment of the present disclosure, the outdoor ambient temperature is obtained by collecting a temperature at an air inlet of the external air passage of the mobile air conditioner, i.e., the outdoor ambient temperature may be obtained by a temperature sensor disposed at the air inlet of the external air passage of the mobile air conditioner.
According to an embodiment of the present disclosure, when the type of the air duct is a single air duct, the air inlet of the external air passage of the mobile air conditioner is in communication with an indoor side; and when the type of the air duct is a dual air duct, the air inlet of the external air passage of the mobile air conditioner is in communication with an outdoor side.
In some embodiments, the types of air ducts are divided into the single air duct and the dual air duct based on the number of exhaust ducts used by the mobile air conditioner. When the mobile air conditioner uses the single air duct for air exhaust, an internal air passage of the mobile air conditioner sucks air from an indoor space, and the air passes through an evaporator and is blown from the internal air passage into the indoor space. The external air passage of the mobile air conditioner sucks air from the indoor space, and the air passes through a condenser and is blown from the external air passage to an outdoor space through an exhaust duct. That is, when the mobile air conditioner uses the single air duct, the air duct is in communication with an air outlet of the external air passage of the mobile air conditioner, and the air inlet of the external air passage of the mobile air conditioner is directly in communication with the indoor space. Then, the outdoor ambient temperature obtained by the temperature sensor installed at the air inlet of the external air passage is actually an air temperature of an indoor environment. Therefore, for the mobile air conditioner using the single air duct, the collected outdoor ambient temperature changes with the change of the indoor ambient temperature, and a temperature difference between the indoor ambient temperature and the outdoor ambient temperature that are collected at the same moment is relatively small or even zero.
When the mobile air conditioner uses the dual air duct for air exhaust, the internal air passage of the mobile air conditioner sucks air from the indoor space, and the air passes through the evaporator and is blown from the internal air passage into the indoor space. The external air passage of the mobile air conditioner sucks air from the outdoor space through an exhaust duct, and the air passes through the condenser and is blown from the external air passage to the outdoor space through another exhaust duct. That is, when the mobile air conditioner uses the dual air duct, the two air ducts has an end respectively in communication with the air inlet and the air outlet of the external air passage of the mobile air conditioner and another end extending to the outdoor space. The outdoor ambient temperature obtained by the temperature sensor installed at the air inlet of the external air passage of the mobile air conditioner is an actual air temperature of an outdoor environment. Therefore, the outdoor ambient temperature obtained by this mobile air conditioner has nothing to do with the indoor ambient temperature.
A detailed description is made to a determination process for determining whether the type of the air duct used by the mobile air conditioner is the dual air duct or the single air duct based on the indoor ambient-temperature change value △T1, the outdoor ambient-temperature change value △T4, and the indoor-outdoor temperature difference △T.
According to an embodiment of the present disclosure, determining the type of the air duct of the mobile air conditioner based on the indoor ambient-temperature change value △T1, the outdoor ambient-temperature change value △T4, and the indoor-outdoor temperature difference △T includes: when the indoor ambient-temperature change value △T1 reaches a first predetermined temperature threshold T1, determining the type of the air duct as a dual air duct in response to the outdoor ambient-temperature change value △T4 being smaller than a second predetermined temperature threshold T2 and the indoor-outdoor temperature difference △T being greater than a third predetermined temperature threshold T3.
According to an embodiment of the present disclosure, determining the type of the air duct of the mobile air conditioner according to the indoor ambient-temperature change value △T1, the outdoor ambient-temperature change value △T4, and the indoor-outdoor temperature difference △T includes: when the indoor ambient-temperature change value △T1 reaches a first predetermined temperature threshold T1, determining the type of the air duct as a single air duct in response to the outdoor ambient-temperature change value △T4 being greater than or equal to a second predetermined temperature threshold T2 or the indoor-outdoor temperature difference △T being smaller than or equal to a third predetermined temperature threshold T3.
In some embodiments, during the operation of the mobile air conditioner, the current indoor ambient temperature T11 is obtained in real-time. Moreover, the current indoor ambient-temperature change value △T1 is determined. The obtained indoor ambient-temperature change value △T1 is compared with the first predetermined temperature threshold T1. In response to the indoor ambient-temperature change value △T1 being smaller than the first predetermined temperature threshold T1, the mobile air conditioner is controlled to continue to operate, and not to obtain the current outdoor ambient temperature T41. The above blocks are repeated until the indoor ambient-temperature change value △T1 is greater than or equal to the first predetermined temperature threshold T1. At this time, the current outdoor ambient temperature T41 is obtained. Moreover, the outdoor ambient-temperature change value △T4 and the current indoor-outdoor temperature difference △T are further calculated. Then, the obtained outdoor ambient-temperature change value △T4 is compared with the second predetermined temperature threshold T2. In response to the outdoor ambient-temperature change value △T4 not reaching the second predetermined temperature threshold T2, it is considered that the current outdoor ambient temperature change is relatively small, and a magnitude relationship between the current indoor-outdoor temperature difference △T and the third predetermined temperature threshold T3 is further determined. In response to the outdoor ambient-temperature change value △T4 reaching the second predetermined temperature threshold T2, it is considered that the current outdoor ambient temperature change is relatively large. The outdoor ambient temperature changes with the change of the indoor ambient temperature. It is determined that the mobile air conditioner adopts the single air duct for air exhaust.
When the outdoor ambient-temperature change value △T4 does not reach the second predetermined temperature threshold T2, in response to the current indoor-outdoor temperature difference △T exceeding the third predetermined temperature threshold T3, it is considered that a temperature difference between the current outdoor ambient temperature T41 and the current indoor ambient temperature T11 of the mobile air conditioner is relatively large. Therefore, the mobile air conditioner is determined to adopt the dual air duct for air exhaust. In response to the current indoor-outdoor temperature difference △T not exceeding the third predetermined temperature threshold T3, it is considered that the temperature difference between the current outdoor ambient temperature T41 and the current indoor ambient temperature T11 of the mobile air conditioner is relatively small. Therefore, the mobile air conditioner is determined to adopt the single air duct for air exhaust.
It should be noted that the first predetermined temperature threshold T1, the second predetermined temperature threshold T2, and the third predetermined temperature threshold T3 may be set as actual situation. For example, in order to ensure an obvious temperature difference effect, the first predetermined temperature threshold T1 may be set to 5°C, 7°C, or the like. The above-mentioned second predetermined temperature threshold T2 is used for determining whether the outdoor ambient temperature has a corresponding temperature change with the change of the indoor ambient temperature. Therefore, the second predetermined temperature threshold T2 may be set based on the first predetermined temperature threshold T1. For example, the second predetermined temperature threshold T2 may be equal to the first predetermined temperature threshold T1 or be a predetermined temperature smaller than the first predetermined temperature threshold T1. In addition, the third predetermined temperature threshold T3 is used for determining the magnitude of the temperature difference between the indoor ambient temperature and the outdoor ambient temperature at the same moment. Since the temperature difference between the indoor ambient temperature and the outdoor ambient temperature at the same moment is relatively small in an exhaust mode with the single air duct, the third predetermined temperature threshold T3 may be smaller than the first temperature threshold T1.
According to an embodiment of the present disclosure, the operating limit parameter includes at least one of a rotational speed limit value of an outdoor fan, a compressor frequency limit value, and an overall current limit value of the mobile air conditioner.
According to an embodiment of the present disclosure, a rotational speed limit value, a compressor frequency limit value, and an overall current limit value of a mobile air conditioner with the single air duct are correspondingly smaller than a rotational speed limit value, a compressor frequency limit value, and an overall current limit value of a mobile air conditioner with the dual air duct, respectively.
That is, after a type of an air duct accessory installed on the machine is determined, a rotational speed limit value of an outdoor fan, a compressor frequency limit value, and an overall current limit value are set in a targeted manner based on the type of the air duct adopted by the mobile air conditioner. In some embodiments, when it is determined that the mobile air conditioner uses the single air duct, a relatively small rotational speed limit value, a relatively small compressor frequency limit value, and a relatively small overall current limit value of the mobile air conditioner are selected for use, to control the mobile air conditioner to operate with relatively small operating limit parameters. When it is determined that the mobile air conditioner uses the dual air duct, a relatively large rotational speed limit value, a relatively large compressor frequency limit value, and a relatively large overall current limit value of the mobile air conditioner are selected for use, to control the mobile air conditioner to operate with relatively large operating limit parameters. In this way, a targeted control optimization of the mobile air conditioner can be achieved, which ensures maximization of the overall performance, and ensures the user experience.
It should be noted that a corresponding relationship table between the operating limit parameter and the type of the air duct may be pre-stored in a data storage unit of the mobile air conditioner. During actual operation of the mobile air conditioner, an actually adopted type of the air duct is determined based on the indoor and outdoor temperatures. Then, the pre-stored relationship table between the operating limit parameter and the type of the air duct is retrieved to determine the corresponding operating limit parameter. Moreover, the mobile air conditioner is controlled to operate with this operating limit parameter. In this way, the mobile air conditioner can have the relatively good performance effect and high reliability under installation situations of the different types of air ducts, improving the user experience.
As a specific embodiment of the present disclosure, a rotational speed limit value S2 is smaller than S1, a compressor frequency limit value F2 is smaller than F1, and an overall current limit value I2 is smaller than I1.
