[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In this application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0044] The terms "first," "second," "third," "fourth," and so on (if any) in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that shown or described herein.

[0045] As can be seen from the background technology, the existing defrost logic relies on the temperature difference between the outer ring temperature and the outdoor coil sensor to control the defrost. When the frost on the outdoor unit is thick, the outdoor heat exchange efficiency deteriorates and the coil temperature drops slowly, resulting in low heating capacity and long-term non-defrost, which leads to a poor user experience.

[0046] Therefore, an embodiment of the present invention provides an air conditioner defrost logic control method, system and related equipment. In this solution, if it is detected in sequence that the outdoor ambient temperature is lower than the first preset temperature, the difference between the outdoor ambient temperature and the outdoor coil sensor temperature is greater than the second preset temperature, and the difference between the indoor coil sensor temperature and the indoor ambient temperature is lower than the third preset temperature, the air conditioner is controlled to enter the defrost mode according to the indoor coil sensor temperature and the indoor ambient temperature to defrost the air conditioner, thereby being able to enter the defrost mode for a long time at low heating capacity, and providing a good user experience.

[0047] like Figure 1 FIG. 1 is a flow chart of an air conditioner defrost logic control method provided by an embodiment of the present invention. The air conditioner defrost logic control method mainly includes the following steps:

[0048] Step S101: After the heating mode of the air conditioner is turned on, the outdoor ambient temperature is detected.

[0049] In step S101 , the outdoor ambient temperature may be expressed as Tao, which may be understood as the outer ring temperature Tao.

[0050] In the specific implementation of step S101, during the operation of the air conditioner, the heating mode is turned on. After the heating mode of the air conditioner is turned on, the outdoor ambient temperature is detected to detect the specific outdoor ambient temperature, that is, to detect the specific value corresponding to the outdoor ambient temperature.

[0051] Step S102: Determine whether the outdoor ambient temperature is greater than or equal to a first preset temperature. If not, execute step S103; if so, execute step S109.

[0052] In the embodiment of the present invention, the first preset temperature may be 10°C.

[0053] In the process of implementing step S102, it is determined whether the specific outdoor ambient temperature detected is greater than or equal to the first preset temperature. If not, it means that the current defrost control logic needs to add coil control. That is to say, after entering the coil control defrost logic, the existing defrost control logic remains unchanged, but a new condition for early entry is added to enter the defrost, then execute step S103. If so, it means that the current defrost control logic is controlled according to the original defrost logic, then execute step S109.

[0054] It is understandable that the determination of whether the outer ring temperature is greater than or equal to 10°C indicates that if not, the current defrost control logic needs to add coil control. In other words, after entering the coil control defrost logic, the existing defrost control logic remains unchanged, but a new condition for early entry is added. In this case, step S103 is executed. If so, the current defrost control logic is controlled according to the original defrost logic, and step S109 is executed.

[0055] It should be noted that the original defrost logic is the existing defrost logic.

[0056] Step S103: Detecting the temperature of the outdoor coil sensor.

[0057] In step S103 , the outdoor coil sensor temperature may be expressed as Tp2 , which may be understood as the outdoor coil Tp2 .

[0058] In the specific implementation of step S103, when it is determined that the outdoor ambient temperature is less than the first preset temperature, or when it is determined that the outer ring temperature Tao is less than 10°C, the outdoor coil sensor temperature is detected.

[0059] It is understandable that after determining that the outdoor ambient temperature is less than the first preset temperature, the coil control defrost logic is entered. After that, the existing defrost control logic remains unchanged, and the outdoor coil sensor temperature is first detected.

[0060] Step S104: Determine whether the difference between the outdoor ambient temperature and the outdoor coil sensor temperature is greater than a second preset temperature. If so, execute step S105; if not, execute step S102.

[0061] In an embodiment of the present invention, the second preset temperature may be 2°C.

[0062] In the specific implementation of step S104, the difference between the outdoor ambient temperature and the outdoor coil sensor temperature is first calculated, that is, outdoor ambient temperature - outdoor coil sensor temperature = specific value. Then, it is determined whether the difference between the outdoor ambient temperature and the outdoor coil sensor temperature is greater than a second preset temperature, that is, whether the specific value is greater than the second preset temperature. If so, step S105 is executed. If not, it means that the difference between the outdoor ambient temperature and the outdoor coil sensor temperature is less than or equal to the second preset temperature, and the process returns to step S102.

[0063] It is understandable that, if the outer ring temperature Tao minus the outer coil Tp2 is greater than 2, the process proceeds to step S105. If not, the process returns to step S102.

[0064] Step S105: Detecting the indoor coil sensor temperature and the indoor ambient temperature.

[0065] In step S105 , the indoor coil sensor temperature may be expressed as Tp1 , which may be understood as the indoor coil Tp1 .

[0066] The indoor ambient temperature can be expressed as Tr, which can be understood as the inner ring temperature Tr.

[0067] In the specific implementation of step S105, when it is determined that the difference between the outdoor ambient temperature and the outdoor coil sensor temperature is greater than the second preset temperature, or when it is determined that the outer ring temperature Tao-outer coil Tp2>2, the indoor coil sensor temperature and the indoor ambient temperature are detected.

[0068] Step S106: Determine whether the difference between the indoor coil sensor temperature and the indoor ambient temperature is less than a third preset temperature. If so, execute step S107; if not, execute step S108.

[0069] In the embodiment of the present invention, the third preset temperature may be 15°C.

[0070] In the specific implementation of step S106, the difference between the indoor coil sensor temperature and the indoor ambient temperature is first calculated, that is, indoor coil sensor temperature - indoor ambient temperature = specific value. Then, it is determined whether the difference between the indoor coil sensor temperature and the indoor ambient temperature is less than a third preset temperature, that is, whether the specific value is less than the third preset temperature. If so, step S107 is executed. If not, it means that the difference between the indoor coil sensor temperature and the indoor ambient temperature is greater than or equal to the third preset temperature, and step S108 is executed.

[0071] It is understandable that, if the inner coil Tp1 minus the inner ring temperature Tr is less than 15, then step S107 is executed. If not, it means that the inner coil Tp1 minus the inner ring temperature Tr is greater than or equal to 15, and then step S108 is executed.

[0072] Step S107: controlling the air conditioner to enter a defrost mode according to the indoor coil sensor temperature and the indoor ambient temperature to defrost the air conditioner.

[0073] In the process of specifically implementing step S107, when it is determined that the difference between the indoor coil sensor temperature and the indoor ambient temperature is less than the third preset temperature, or when it is determined that the inner coil Tp1-inner ring temperature Tr<15, the air conditioner is controlled to enter the defrost mode according to the indoor coil sensor temperature and the indoor ambient temperature to defrost the air conditioner.

[0074] Step S108: Determine whether the original defrost determination condition is met. If so, execute step S109; if not, execute step S104.

[0075] It should be noted that the original defrost determination condition is the temperature difference between the outdoor ambient temperature and the outdoor coil sensor temperature.

[0076] In the process of implementing step S108, when it is determined that the difference between the indoor coil sensor temperature and the indoor ambient temperature is greater than or equal to the third preset temperature, or when it is determined that the inner coil Tp1-inner ring temperature Tr>=15, it is judged whether the original defrost judgment condition is met. If so, execute step S109, if not, execute step S104.

[0077] Step S109: performing defrost control on the air conditioner according to the temperature difference between the outdoor ambient temperature and the outdoor coil sensor temperature, and controlling the air conditioner to enter a defrost mode to defrost the air conditioner.

[0078] In the process of specifically implementing step S109, when it is determined that the current air conditioner meets the original defrost judgment conditions, the temperature difference between the outdoor ambient temperature and the outdoor coil sensor temperature is calculated, and the air conditioner is defrosted based on the temperature difference, and the air conditioner is controlled to enter the defrost mode to defrost the air conditioner.

[0079] Step S110: Control the air conditioner to operate normally, and return to re-determine whether the outdoor ambient temperature is greater than or equal to the first preset temperature.

[0080] In the specific implementation of step S110 , after the air conditioner is controlled to enter the defrost mode to complete defrosting, the air conditioner is controlled to operate normally, and returns to re-determine whether the outdoor ambient temperature is greater than or equal to the first preset temperature.

[0081] An air conditioner defrost logic control method provided by an embodiment of the present invention detects the outdoor ambient temperature after the air conditioner's heating mode is turned on; determines whether the outdoor ambient temperature is greater than or equal to a first preset temperature; if not, detects the outdoor coil sensor temperature; determines whether the difference between the outdoor ambient temperature and the outdoor coil sensor temperature is greater than a second preset temperature; if so, detects the indoor coil sensor temperature and the indoor ambient temperature; determines whether the difference between the indoor coil sensor temperature and the indoor ambient temperature is less than a third preset temperature; if so, controls the air conditioner to enter a defrost mode based on the indoor coil sensor temperature and the indoor ambient temperature to defrost the air conditioner. In this solution, if it is sequentially detected that the outdoor ambient temperature is less than the first preset temperature, the difference between the outdoor ambient temperature and the outdoor coil sensor temperature is greater than the second preset temperature, and the difference between the indoor coil sensor temperature and the indoor ambient temperature is less than the third preset temperature, the air conditioner is controlled to enter a defrost mode based on the indoor coil sensor temperature and the indoor ambient temperature to defrost the air conditioner, thereby enabling the air conditioner to enter defrost mode for a long time at low heating capacity, providing a good user experience.

[0086] The second judgment module 204 is used to judge whether the difference between the outdoor ambient temperature and the outdoor coil sensor temperature is greater than a second preset temperature. If so, the third detection module 205 is executed; if not, the process returns to the first judgment module 202 for execution.
