Description

Technical Field

[0002] Currently, the heating start mode of variable-frequency air conditioners is the same under any outdoor environmental temperature and installation conditions.

[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] Refer to Figure 1 , Figure 1 Schematic diagram of the air conditioner structure of the hardware operating environment involved in the embodiment solution of the present invention.

[0050] As Figure 1 shown, the air conditioner may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005.

Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0051] Those skilled in the art can understand that Figure 1 the device structure shown in

[0052] does not constitute a limitation on the air conditioner, and may include more or fewer components than shown in the figure, or combine some components, or arrange different components. Figure 1 As

[0053] In Figure 1In the air conditioner shown, the network interface 1004 is mainly used to connect to the external network and communicate data with other network devices; the user interface 1003 is mainly used to connect to user devices and communicate data with the user devices; the device of the present invention calls the air conditioner heating start control program stored in the memory 1005 through the processor 1001 and executes the air conditioner heating start control method provided by the embodiments of the present invention.

[0054] Based on the above hardware structure, an embodiment of the air conditioner heating start control method of the present invention is proposed.

[0055] Refer to Figure 2 , Figure 2 which is a schematic flowchart of the first embodiment of the air conditioner heating start control method of the present invention.

[0056] In the first embodiment, the air conditioner heating start control method includes the following steps:

[0057] Step S10, when receiving a heating start instruction, obtain the height difference between the indoor unit and the outdoor unit, and the length of the connecting pipe between the indoor unit and the outdoor unit.

[0058] It should be noted that the execution subject of this embodiment can be an air conditioner, such as a cabinet air conditioner or a wall-mounted air conditioner, or other types of air conditioners. This embodiment does not limit this. In this embodiment, the air conditioner is taken as an example for illustration.

[0059] It should be understood that the air conditioner in this embodiment can specifically be an inverter air conditioner, and the compressor can specifically be an inverter compressor. This embodiment does not limit the specific models of the inverter air conditioner and the inverter compressor. The heating start instruction in this embodiment can be input by the user through the buttons on the air conditioner remote control, or by the user's voice input, or by the user's voice input, or by other means. This embodiment does not limit this.

[0060] It should be noted that the air conditioner includes an indoor unit and an outdoor unit. The indoor unit is installed indoors, and the outdoor unit is installed outdoors. Generally speaking, in order for the air conditioner to operate normally, there will be a certain height difference between the installation positions of the indoor unit and the outdoor unit.

[0061] It should be understood that the height difference in this embodiment refers to the vertical height difference between the indoor unit and the outdoor unit of the air conditioner. Since the indoor unit and the outdoor unit of the air conditioner can be connected by a connecting pipe, the refrigerant flows between the indoor unit and the outdoor unit through the connecting pipe to form a refrigeration cycle or a heating cycle to achieve the refrigeration or heating effect. And the connecting pipe can be divided into a high-pressure pipe and a low-pressure pipe. Therefore, the length of the connecting pipe in this embodiment can be the total length of the connecting pipe between the indoor unit and the outdoor unit.

[0062] It can be understood that the connecting pipe of the air conditioner can be a copper pipe or a pipe made of other materials. This embodiment does not limit this. In this embodiment, the connecting pipe is taken as an example of a copper pipe for illustration. The refrigeration principle of the air conditioner is as follows: When the air conditioner is in the working state, the compressor of the outdoor unit compresses the refrigerant, converting the gaseous refrigerant into a liquid refrigerant and releasing heat. The liquid refrigerant enters the condenser (radiator) of the outdoor unit, and the control fan discharges the heat generated during compression to the outdoor environment, converting the liquid refrigerant into a liquid refrigerant with a lower temperature. After the liquid refrigerant comes out of the condenser (radiator), it passes through the relatively thin pipe (referred to as the high-pressure pipe) connecting the indoor unit and the outdoor unit, enters the throttle before the evaporator of the indoor unit, and enters the evaporator of the indoor unit after coming out of the throttle. The liquid refrigerant can quickly vaporize in the evaporator and absorb a large amount of heat around the evaporator. Since a large amount of heat around the evaporator of the indoor unit is absorbed by the refrigerant, the blower in the indoor unit can blow cold air into the indoor space, thus achieving the refrigeration effect. After the refrigerant comes out of the evaporator of the indoor unit, it can pass through the relatively thick pipe (referred to as the low-pressure pipe) connecting the indoor and outdoor units and enter the compressor of the outdoor unit again. In this way, the cycle repeats, and the refrigeration effect on the indoor space can be produced. The heating principle of the air conditioner is similar to the above refrigeration principle and will not be elaborated here.

[0063] From the operating principle of the air conditioner, it can be seen that during the refrigeration and heating processes of the air conditioner, the lengths of the low-pressure pipe and the high-pressure pipe have a certain impact on the operation of the air conditioner. Therefore, in this application, in order to achieve a better heating start control effect, when determining the heating start strategy, the connecting pipe length of the air conditioner can be considered and used as a consideration factor to control the compressor, thereby controlling the compressor more reasonably and improving the service life of the compressor.

[0064] In specific implementation, the height difference and the connecting pipe length can be determined through the installation record information. For example, when the staff installs the air conditioner, various installation information can be recorded and entered into the system for subsequent air conditioner control. When the controller of the air conditioner receives the heating start instruction input by the user, it can obtain the installation record information corresponding to the air conditioner, determine the indoor unit information and the outdoor unit information according to the installation record information, determine the indoor unit height according to the indoor unit information, and determine the outdoor unit height according to the outdoor unit information. Subtract the outdoor unit height from the indoor unit height to determine the height difference between the indoor unit and the outdoor unit. For example, the indoor unit height can be subtracted from the outdoor unit height, or the outdoor unit height can be subtracted from the indoor unit height to obtain the height difference, and then the absolute value of the height difference is used as the height difference.

[0065] It should be understood that when determining the height of the indoor unit and the outdoor unit, the center points of the indoor unit and the outdoor unit can be used as the reference points to determine the height, or the highest point or the lowest point of the indoor unit and the outdoor unit can be used as the reference points to determine the height. There are also other ways to determine the height of the indoor unit and the outdoor unit, and this embodiment does not limit this.

[0066] In one embodiment, since the usage scenarios of each air conditioner are not necessarily the same, the connection pipe length corresponding to the air conditioner can be calculated in advance, and the connection pipe length can be used as one type of connection pipe information. The connection pipe information can be determined according to the installation record information, and the connection pipe length can be extracted from the connection pipe information. In another embodiment, the connection pipe length does not need to be calculated in advance. During the control process, the connection pipe information can be determined according to the installation record information, the high-pressure pipe length and the low-pressure pipe length can be extracted from the connection pipe information, and the connection pipe length can be obtained by adding the high-pressure pipe length and the low-pressure pipe length. In addition to the above methods, there are also other ways to determine the connection pipe length, and this embodiment does not limit this.

[0067] In specific implementation, for example, when the staff installs the air conditioner, the high-pressure pipe length corresponding to the high-pressure pipe of the air conditioner and the low-pressure pipe length corresponding to the low-pressure pipe can be determined, and the high-pressure pipe length and the low-pressure pipe length are added together. The parameter obtained by addition is used as the connection pipe length corresponding to the air conditioner, and the obtained connection pipe length is used as one type of connection pipe information. At the same time, after the air conditioner is installed, the staff can also detect the indoor unit height and the outdoor unit height corresponding to the indoor unit and the outdoor unit respectively, and use them as the indoor unit information and the outdoor unit information respectively. The obtained connection pipe information, indoor unit information and outdoor unit information are stored as the air conditioner installation information in the data storage area corresponding to the air conditioner.

[0068] In another embodiment, after the air conditioner is installed, the staff can directly detect the height difference between the indoor unit and the outdoor unit, use the height difference as the drop height, use the drop height as one type of indoor unit information, and at the same time use the drop height as one type of outdoor unit information. During the heating startup process, directly obtain the indoor unit information and / or outdoor unit information in the air conditioner installation information, and determine the drop height according to the indoor unit information and / or outdoor unit information. Which specific means to use can be determined according to the actual usage scenario, and this embodiment does not limit this.

[0069] Step S20, determine the corresponding heating startup strategy according to the drop height and the connection pipe length, and control the operating state of the compressor according to the heating startup strategy to complete the heating startup of the air conditioner.

[0070] It should be understood that for the case where the heating start-up method of a traditional air conditioner is the same under any conditions, this embodiment proposes a new method for selecting a heating start-up method based on the height difference and the length of the connecting pipe. After determining the height difference and the length of the connecting pipe, logical judgment can be made based on the height difference and the length of the connecting pipe to determine the heating start-up strategy corresponding to the current usage scenario. Then, the compressor of the air conditioner can be controlled according to the determined heating start-up strategy to adjust the operating state of the compressor, thereby completing the heating start-up of the air conditioner.

[0071] In this embodiment, the solution of this embodiment is different from the situation where the heating start-up method of a traditional air conditioner is the same under any conditions. During the heating start-up process, a suitable heating start-up strategy is determined according to the height difference and the length of the connecting pipe for heating start-up, which improves the low-pressure pressure during heating start-up and extends the service life of the compressor.

[0072] In one embodiment, as Figure 3 shown, based on the first embodiment, the second embodiment of the air conditioner heating start-up control method of the present invention is proposed. The step S20 includes:

[0073] Step S201: Compare the height difference with a first preset height threshold to obtain a first comparison result.

[0074] It should be noted that a first preset height threshold h1 can be set in advance. Among them, the first preset height threshold h1 can be set according to the specific model of the air conditioner and the actual usage situation, and the specific value of this embodiment is not limited.

[0075] It should be understood that the height difference H and the first preset height threshold h1 can be compared to obtain a first comparison result. In this embodiment, the first comparison result can be H≥h1 or H<h1.

[0076] Step S202: Compare the length of the connecting pipe with a first preset length threshold to obtain a second comparison result.

[0077] It should be noted that a first preset length threshold l1 can be set in advance. Among them, the first preset length threshold l1 can be set according to the specific model of the air conditioner and the actual usage situation, and the specific value of this embodiment is not limited.

[0078] It should be understood that the length of the connecting pipe L and the first preset length threshold l1 can be compared to obtain a second comparison result. In this embodiment, the second comparison result can be L≥l1 or L<l1.

[0079] Step S203: Determine the corresponding heating start-up strategy according to the first comparison result and the second comparison result, and control the operating state of the compressor according to the heating start-up strategy to complete the heating start-up of the air conditioner.

[0080] It should be noted that the above two steps can be carried out simultaneously, or step S201 can be carried out first and then step S202, or step S202 can be carried out first and then step S201. This embodiment does not limit this. In this embodiment, taking these two steps being carried out simultaneously as an example for illustration.

[0081] It should be understood that after obtaining the first comparison result and the second comparison result through the above steps, the first comparison result and the second comparison result can be combined to determine the heating start-up strategy corresponding to the current usage scenario through these two comparison results. Then, control the compressor of the air conditioner according to the determined heating start-up strategy, adjust the operating state of the compressor, so as to complete the heating start-up of the air conditioner. Since there are multiple comparison results, therefore, in the case of obtaining different comparison results, different heating start-up strategies corresponding to the current scenario can be determined, and the operating state of the compressor can be controlled through the most appropriate heating start-up strategy to achieve a better heating start-up control effect.

[0082] In this embodiment, when the drop height and the connecting pipe length meet certain conditions, the compressor can be controlled in two stages at a preset rate, frequency and operating time, and then its normal operating state can be obtained, so as to complete the heating start-up of the air conditioner, improve the low-pressure pressure during heating start-up, and extend the service life of the compressor.

[0083] In one embodiment, as Figure 4 shown, based on the second embodiment, the third embodiment of the air conditioner heating start-up control method of the present invention is proposed. The step S203 includes:

[0084] Step S2031: When the drop height is greater than or equal to the first preset height threshold, or the connecting pipe length is greater than or equal to the first preset length threshold, control the compressor to increase the frequency to the first preset frequency at the first preset rate, and operate at the first preset frequency for the first preset time.

[0085] It should be noted that the first preset rate v1, the first preset frequency f1 and the first preset time t1 can be preset. Among them, the first preset rate v1, the first preset frequency f1 and the first preset time t1 can be set according to the specific model of the air conditioner and the actual usage situation. This embodiment does not limit their specific values.

[0086] It should be understood that after the above comparison, when the drop height H is greater than or equal to the first preset height threshold h1, or the length L of the connecting pipe is greater than or equal to the first preset length threshold l1, that is, when the condition of H≥h1 or L≥l1 is satisfied, the compressor can be controlled to increase its frequency to the first preset frequency f1 at the first preset rate v1 and operate at the first preset frequency f1 for the first preset time t1.

[0087] Step S2032: Control the compressor to increase its frequency to a second preset frequency at a second preset rate and operate at the second preset frequency for a second preset time, where the second preset frequency is greater than the first preset frequency.

[0088] It should be noted that the second preset rate v2, the second preset frequency f2, and the second preset time t2 can be preset. Among them, the second preset rate v2, the second preset frequency f2, and the second preset time t2 can be set according to the specific model of the air conditioner and the actual usage situation, and the specific values thereof are not limited in this embodiment. Among them, the second preset frequency f2 is greater than the first preset frequency f1.

[0089] It should be understood that after controlling the compressor to operate at the first preset frequency f1 for the first preset time t1, the compressor can be controlled to increase its frequency to the second preset frequency f2 at the second preset rate v2 and operate at the second preset frequency f2 for the second preset time t2.

[0090] Step S2033: Control the air conditioner to enter the normal operation state to complete the start-up of air-conditioning heating.

[0091] It should be understood that after controlling the compressor to operate at the second preset frequency f2 for the second preset time t2, the compressor can be controlled to operate normally to make the air conditioner enter the normal operation state, thereby completing the start-up of air-conditioning heating. Among them, the normal operation state of the air conditioner refers to the conventional operation state of the air conditioner according to the mode and temperature set by the user. This embodiment is directed to this process of air-conditioning start-up, and the start-up process is improved. After the air-conditioning start-up is completed, the air conditioner is controlled to operate normally.

[0092] It can be understood that in this embodiment, the control of the compressor is divided into two stages, which can be called the first stage and the second stage. In the first stage, the compressor is controlled to increase its frequency at the first preset rate, and when the frequency of the compressor reaches the first preset frequency, the compressor is controlled to maintain the first preset frequency and continue to operate for the first preset time. After continuing for the first preset time, it enters the second stage. In the second stage, the compressor is controlled to increase its frequency at the second preset rate, and when the frequency of the compressor reaches the second preset frequency, the compressor is controlled to maintain the second preset frequency and continue to operate for the second preset time. After continuing for the second preset time, the compressor can be controlled to operate normally to make the air conditioner enter the normal operation state, thereby completing the start-up of air-conditioning heating.

[0093] In another embodiment, since there are other comparison results, in the usage scenarios corresponding to the other comparison results, in order to improve the control effect of the air conditioner's heating startup, other heating startup strategies can also be selected. Step S203 may further include:

[0094] When the drop height is less than the first preset height threshold and the connecting pipe length is less than the first preset length threshold, obtain the outdoor ambient temperature; when the drop height is greater than the second preset height threshold, or the connecting pipe length is greater than the second preset length threshold and the outdoor ambient temperature is less than the first preset temperature threshold, control the compressor to increase the frequency to the first preset frequency at the first preset rate and operate at the first preset frequency for the first preset time, where the second preset height threshold is less than the first preset height threshold and the second preset length threshold is less than the first preset length threshold; control the compressor to increase the frequency to the second preset frequency at the second preset rate and operate at the second preset frequency for the second preset time; control the air conditioner to enter the normal operation state to complete the heating startup of the air conditioner.

[0095] It should be understood that when the air conditioner is heating, the lower the outdoor ambient temperature, the lower the low pressure during startup, which affects the service life of the compressor. The existing control methods do not consider the influence of low temperature environment. In the solution of this embodiment, when the drop height H is less than the first preset height threshold h1 and the connecting pipe length H is less than the first preset length threshold l1, that is, when H < h1 and L < l1, the outdoor ambient temperature T can be obtained. On the basis of combining the drop height and the connecting pipe length, the outdoor ambient temperature is further combined to select a suitable heating startup strategy. Among them, the outdoor ambient temperature can be detected by a temperature sensor, obtained through the network, or determined by other means. This embodiment does not limit this.

[0096] It should be noted that the second height threshold h2, the second length threshold l2, the first preset temperature threshold T1, and the second preset temperature threshold T2 can be set in advance. The second height threshold h2, the second length threshold l2, the first preset temperature threshold T1, and the second preset temperature threshold T2 can be set according to the specific model of the air conditioner and the actual usage situation. This embodiment does not limit their specific values. Among them, the second preset height threshold h2 is less than the first preset height threshold h1, the second preset length threshold l2 is less than the first preset length threshold l1, and the second preset temperature threshold T2 is less than the first preset temperature threshold T1.

[0097] It should be understood that the drop height can be further compared with the second preset height threshold, the connecting pipe length can be compared with the second preset length threshold, and the outdoor ambient temperature can be compared with the first preset temperature threshold. After obtaining the outdoor ambient temperature, it further includes:

[0098] When the height difference is less than or equal to the second preset height threshold and the length of the connecting pipe is less than or equal to the second preset length threshold, compare the outdoor ambient temperature with the second preset temperature threshold, where the second preset temperature threshold is less than the first preset temperature threshold; when the outdoor ambient temperature is less than the second preset temperature threshold, control the compressor to increase its frequency at a first preset rate to a first preset frequency and operate at the first preset frequency for a first preset time; control the compressor to increase its frequency at a second preset rate to a second preset frequency and operate at the second preset frequency for a second preset time; control the air conditioner to enter the normal operation state to complete the start-up of air conditioner heating.

[0099] It should be understood that when the conditions of h2 < H < h1 or l2 < L < l1 and T < T1 are satisfied, the compressor can be controlled to increase its frequency at a first preset rate v1 to a first preset frequency f1, and operate at the first preset frequency f1 for a first preset time t1, and control the compressor to increase its frequency at a second preset rate v2 to a second preset frequency f2, and operate at the second preset frequency f2 for a second preset time t2, and then control the compressor to operate normally to make the air conditioner enter the normal operation state.

[0100] In another embodiment, when the above conditions are not met, further judgment can be continued. After comparing the outdoor ambient temperature with the second preset temperature threshold, it further includes:

[0101] When the height difference is less than or equal to the second preset height threshold and the length of the connecting pipe is less than or equal to the second preset length threshold, compare the outdoor ambient temperature with the second preset temperature threshold, where the second preset temperature threshold is less than the first preset temperature threshold; when the outdoor ambient temperature is less than the second preset temperature threshold, control the compressor to increase its frequency at a first preset rate to a first preset frequency and operate at the first preset frequency for a first preset time; control the compressor to increase its frequency at a second preset rate to a second preset frequency and operate at the second preset frequency for a second preset time; control the air conditioner to enter the normal operation state to complete the start-up of air conditioner heating.

[0102] It should be understood that when H ≤ h2 and L ≤ l2, the outdoor ambient temperature can be compared with the second preset temperature threshold. When the condition of T < T2 is satisfied, the compressor can be controlled to increase its frequency at a first preset rate v1 to a first preset frequency f1, and operate at the first preset frequency f1 for a first preset time t1, and control the compressor to increase its frequency at a second preset rate v2 to a second preset frequency f2, and operate at the second preset frequency f2 for a second preset time t2, and then control the compressor to operate normally to make the air conditioner enter the normal operation state.

[0103] It should be noted that a third preset rate v can be preset in advancea and the third preset frequency f a and the fourth preset rate v b and the fourth preset frequency f b and the third preset time t a and the fourth preset time t b wherein, the third preset rate v a and the third preset frequency f a and the fourth preset rate v b and the third preset time t a and the fourth preset time t b can be set according to the specific model of the air conditioner and the actual usage situation, and the specific values thereof are not limited in this embodiment. Among them, the third preset rate v a is greater than the first preset rate v1, the third preset frequency f a is greater than the first preset frequency f1, the third preset time t a is less than the first preset time t1, the fourth preset rate v b is greater than the second preset rate v2, the fourth preset frequency f b is greater than the second preset frequency f2, the fourth preset frequency f b is greater than the third preset frequency f a and the fourth preset time t b is less than the second preset time t2.

[0104] In another embodiment, after comparing the outdoor ambient temperature with the second preset temperature threshold, the method further includes:

[0105] When the outdoor ambient temperature is greater than or equal to the second preset temperature threshold, controlling the compressor to increase the frequency to the third preset frequency at the third preset rate, and operating at the third preset frequency for the third preset time, where the third preset rate is greater than the first preset rate, the third preset frequency is greater than the first preset frequency, and the third preset time is less than the first preset time; controlling the compressor to increase the frequency to the fourth preset frequency at the fourth preset rate, and operating at the fourth preset frequency for the fourth preset time, where the fourth preset rate is greater than the second preset rate, the fourth preset frequency is greater than the second preset frequency, the fourth preset frequency is greater than the third preset frequency, and the fourth preset time is less than the second preset time; controlling the air conditioner to enter the normal operation state to complete the start of air conditioner heating.

[0106] It should be understood that, in the case where the above conditions are still not met, that is, when the outdoor ambient temperature T is greater than or equal to the second preset temperature threshold T2, the compressor can be controlled to increase the frequency to the third preset frequency f a at the third preset rate v a and operate at the third preset frequency f a for the third preset time t aand control the compressor to increase the frequency to the fourth preset rate v b and increase the frequency to the fourth preset frequency f b and run at the fourth preset frequency f b for the fourth preset time t b Then control the compressor to run normally, so that the air conditioner enters the normal operating state.

[0107] It can be understood that the control of the compressor in this embodiment is divided into two stages, which can be called the first stage and the second stage. In the first stage, the compressor is controlled to increase the frequency at the third preset rate, and when the frequency of the compressor reaches the third preset frequency, the compressor is controlled to maintain the third preset frequency and run continuously for the third preset time. After running continuously for the third preset time, it enters the second stage. In the second stage, the compressor is controlled to increase the frequency at the fourth preset rate, and when the frequency of the compressor reaches the fourth preset frequency, the compressor is controlled to maintain the fourth preset frequency and run continuously for the fourth preset time. After running continuously for the fourth preset time, the compressor can be controlled to run normally, so that the air conditioner enters the normal operating state, thereby completing the start-up of air-conditioning heating.

[0108] In a specific implementation, the logic control diagram of this embodiment can be as Figure 5 shown. When starting heating, judge the conditions of the drop H≥h1 or the connecting pipe length L≥l1. If satisfied, the compressor increases the frequency to the first platform at the rate of v1, runs at the frequency value of f1 for the time t1 on the first platform, then increases the frequency to the second platform at the rate of v2, and runs at the frequency value of f2 for the time t2 on the second platform, and finally runs normally; if not satisfied, then judge the conditions of h2<H<h1 or l2<L<l1 and the system detects that the outdoor ambient temperature T<T1. If satisfied, the compressor increases the frequency to the first platform at the rate of v1, runs at the frequency value of f1 for the time t1 on the first platform, then increases the frequency to the second platform at the rate of v2, and runs at the frequency value of f2 for the time t2 on the second platform, and finally runs normally; if still not satisfied, finally judge the condition of T<T2. If satisfied, the compressor increases the frequency to the first platform at the rate of v1, runs at the frequency value of f1 for the time t1 on the first platform, then increases the frequency to the second platform at the rate of v2, and runs at the frequency value of f2 for the time t2 on the second platform, and finally runs normally; if still not satisfied, the compressor increases the frequency to the first platform at the rate of v a rate, runs at the frequency value of f a for the time t a on the first platform, then increases the frequency to the second platform at the rate of v b and runs at the frequency value of f b for the time t b on the second platform, and finally runs normally. The magnitude relationship of each value is h2<h1, l2<l1, T2<T1, v1<v a , f1<f a , t1>ta 、 f1 < f2, v2 < v b 、 f2 < f b 、 t2 > t b 、 f a < f b 。

[0109] In this embodiment, under certain conditions, the outdoor ambient temperature can also be combined with the drop height and the length of the connecting pipe to select a suitable heating start strategy to control the compressor, so that the air conditioner can achieve a better heating start effect in different usage scenarios, avoiding possible interference, improving the low-pressure pressure during heating start, extending the service life of the compressor, and enhancing the user experience.

[0110] In addition, an embodiment of the present invention also provides a storage medium, on which an air conditioner heating start control program is stored. When the air conditioner heating start control program is executed by a processor, the steps of the air conditioner heating start control method described above are implemented.

[0111] Since this storage medium adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated herein one by one.

[0112] In addition, referring to Figure 6 , an embodiment of the present invention also provides an air conditioner heating start control device, and the air conditioner heating start control device includes:

[0113] An information acquisition module 10, configured to acquire the drop height between the indoor unit and the outdoor unit, and the length of the connecting pipe between the indoor unit and the outdoor unit when receiving a heating start instruction.

[0114] It should be understood that the air conditioner in this embodiment may specifically be a variable-frequency air conditioner, and the compressor may specifically be a variable-frequency compressor. The specific models of the variable-frequency air conditioner and the variable-frequency compressor are not limited in this embodiment. The heating start instruction in this embodiment can be input by the user through the buttons on the air conditioner remote control, or by the user's voice input, or by the user's voice input, or by other means, and this embodiment does not limit this.

[0115] It should be noted that the air conditioner includes an indoor unit and an outdoor unit. The indoor unit is installed indoors, and the outdoor unit is installed outdoors. Generally speaking, for the normal operation of the air conditioner, there will be a certain height difference between the installation positions of the indoor unit and the outdoor unit.

[0116] It should be understood that the height difference in this embodiment refers to the vertical height difference between the indoor unit and the outdoor unit of the air conditioner. Since the indoor unit and the outdoor unit of the air conditioner can be connected by connecting pipes, and the refrigerant flows between the indoor unit and the outdoor unit through the connecting pipes to form a refrigeration cycle or a heating cycle to achieve the refrigeration or heating effect, and the connecting pipes can be divided into a high-pressure pipe and a low-pressure pipe. Therefore, the length of the connecting pipe in this embodiment can be the total length of the connecting pipes between the indoor unit and the outdoor unit.

[0117] It can be understood that the connecting pipe of the air conditioner can be a copper pipe or a pipe made of other materials. This embodiment does not limit this. In this embodiment, the connecting pipe is taken as an example of a copper pipe for illustration. The refrigeration principle of the air conditioner is as follows: When the air conditioner is in the working state, the compressor of the outdoor unit compresses the refrigerant, converting the gaseous refrigerant into a liquid refrigerant and releasing heat. The liquid refrigerant enters the condenser (radiator) of the outdoor unit, and the control fan discharges the heat generated during compression to the outdoor environment, converting the liquid refrigerant into a liquid refrigerant with a lower temperature. After the liquid refrigerant comes out of the condenser (radiator), it passes through the relatively thin pipe (referred to as the high-pressure pipe) connecting the indoor unit and the outdoor unit, enters the throttle before the evaporator of the indoor unit, and then enters the evaporator of the indoor unit after coming out of the throttle. The liquid refrigerant can quickly vaporize in the evaporator and absorb a large amount of heat around the evaporator. Since a large amount of heat around the evaporator of the indoor unit is absorbed by the refrigerant, the blower in the indoor unit can blow cold air into the indoor space, thus achieving the refrigeration effect. After the refrigerant comes out of the evaporator of the indoor unit, it can pass through the relatively thick pipe (referred to as the low-pressure pipe) connecting the indoor and outdoor units and enter the compressor of the outdoor unit again. In this way, the cycle repeats, and the refrigeration effect on the indoor can be produced. The heating principle of the air conditioner is similar to the above refrigeration principle and will not be elaborated here.

[0118] From the operating principle of the air conditioner, it can be seen that during the refrigeration and heating processes of the air conditioner, the lengths of the low-pressure pipe and the high-pressure pipe have a certain impact on the operation of the air conditioner. Therefore, in this application, in order to achieve a better heating start control effect, when determining the heating start strategy, the length of the connecting pipe of the air conditioner can be considered and used as a consideration factor to control the compressor, so as to control the compressor more reasonably and improve the service life of the compressor.

[0119] In a specific implementation, the height difference and the length of the connecting pipe can be determined by the installation record information. For example, when the staff installs the air conditioner, various installation information can be recorded and entered into the system for subsequent air conditioner control. When the controller of the air conditioner receives the heating start instruction input by the user, it can obtain the installation record information corresponding to the air conditioner, determine the indoor unit information and the outdoor unit information according to the installation record information, determine the height of the indoor unit according to the indoor unit information, and determine the height of the outdoor unit according to the outdoor unit information, and subtract the height of the outdoor unit from the height of the indoor unit to determine the height difference between the indoor unit and the outdoor unit. For example, the height of the indoor unit can be subtracted from the height of the outdoor unit, or the height of the outdoor unit can be subtracted from the height of the indoor unit to obtain the height difference, and then the absolute value of the height difference is used as the height difference.

[0120] It should be understood that when determining the height of the indoor unit and the outdoor unit, the center points of the indoor unit and the outdoor unit can be used as the reference points to determine the height, or the highest point or the lowest point of the indoor unit and the outdoor unit can be used as the reference points to determine the height, and other methods can also be used to determine the height of the indoor unit and the outdoor unit. This embodiment does not limit this.

[0121] In one embodiment, since the usage scenarios of each air conditioner are not necessarily the same, the length of the connecting pipe corresponding to the air conditioner can be calculated in advance, and the length of the connecting pipe is used as a kind of connecting pipe information. The connecting pipe information can be determined according to the installation record information, and the length of the connecting pipe is extracted from the connecting pipe information. In another embodiment, the length of the connecting pipe does not need to be calculated in advance. During the control process, the connecting pipe information can be determined according to the installation record information, the length of the high-pressure pipe and the length of the low-pressure pipe are extracted from the connecting pipe information, and the length of the high-pressure pipe and the length of the low-pressure pipe are added to obtain the length of the connecting pipe. In addition to the above methods, other methods can also be used to determine the length of the connecting pipe. This embodiment does not limit this.

[0122] In a specific implementation, for example, when the staff installs the air conditioner, the length of the high-pressure pipe corresponding to the high-pressure pipe of the air conditioner and the length of the low-pressure pipe corresponding to the low-pressure pipe can be determined, and the length of the high-pressure pipe and the length of the low-pressure pipe are added, and the obtained parameter is used as the length of the connecting pipe corresponding to the air conditioner, and the obtained length of the connecting pipe is used as a kind of connecting pipe information. At the same time, after the installation of the air conditioner is completed, the staff can also detect the height of the indoor unit and the height of the outdoor unit corresponding to the indoor unit and the outdoor unit respectively, and use them as the indoor unit information and the outdoor unit information respectively, and store the obtained connecting pipe information, indoor unit information and outdoor unit information as the air conditioner installation information in the data storage area corresponding to the air conditioner.

[0123] In another embodiment, after the air conditioner is installed, the staff can directly detect the height difference between the indoor unit and the outdoor unit, use this height difference as the drop height, regard the drop height as one type of indoor unit information, and at the same time regard the drop height as one type of outdoor unit information. During the heating startup process, directly obtain the indoor unit information and / or outdoor unit information in the air conditioner installation information, and determine the drop height according to the indoor unit information and / or outdoor unit information. Specifically, which means to use can be determined according to the actual usage scenario, and this embodiment does not limit this.

[0124] The status control module 20 is used to determine the corresponding heating startup strategy according to the drop height and the connecting pipe length, and control the operating state of the compressor according to the heating startup strategy to complete the heating startup of the air conditioner.

[0125] It should be understood that for the situation where the heating startup method of traditional air conditioners is the same under any conditions, this embodiment proposes a new method for selecting the heating startup method according to the drop height and the connecting pipe length. After determining the drop height and the connecting pipe length, logical judgment can be made according to the drop height and the connecting pipe length to determine the corresponding heating startup strategy. Then, the compressor of the air conditioner can be controlled according to the determined heating startup strategy, and the operating state of the compressor can be adjusted to complete the heating startup of the air conditioner.

[0126] In this embodiment, the solution of this embodiment is different from the situation where the heating startup method of traditional air conditioners is the same under any conditions. During the heating startup process, a suitable heating startup strategy is determined according to the drop height and the connecting pipe length for heating startup, which improves the low-pressure pressure during heating startup and prolongs the service life of the compressor.

[0127] For other embodiments or specific implementation methods of the air conditioner heating startup control device of the present invention, reference can be made to the above method embodiments, and details are not described here again.
