As shown in fig. 2, a certain amount of refrigerant 3 is stored in a liquid storage tank 2 (originally, the liquid storage tank has a function of gas-liquid separation to prevent liquid refrigerant from entering the compressor to cause wet compression and damage to the compressor) connected to the compressor 1, and a hole 4 is opened in a pipe of the liquid storage tank (originally, a pipe of the liquid storage tank through which gaseous refrigerant from the evaporator enters the liquid storage tank and then flows to the compressor) to serve as a passage for supplementing the refrigerant. In some embodiments, a switch is disposed on the hole 4, and the switch can open the hole or close the hole, and open the hole, so that the refrigerant stored in the liquid storage tank can be flashed into the compressor 1, and thus, a cooling or heating cycle can be performed; the orifice is closed when there is no need for make-up refrigerant.
Fig. 1 is a schematic method diagram of an embodiment of an air conditioner control method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner control method includes at least step S110, step S120, and step S130.
Step S110, after the air conditioner is started, detecting a first temperature rise temperature (temperature rise value) or a first temperature drop temperature (temperature drop value) of a room in which the air conditioner is located from when the air conditioner starts to operate to when the air conditioner operates for a preset time.
Detecting a first room temperature of a room where the air conditioner starts to operate and a second room temperature of the room where the air conditioner operates after a preset time, and calculating a first temperature rise temperature or a first temperature drop temperature of the room according to the first room temperature and the second room temperature. Under the condition of the cooling operation of the air conditioner, calculating a first temperature drop temperature of the room according to the first room temperature and the second room temperature, namely a temperature difference value between the first room temperature and the second room temperature; in the case of the air-conditioning heating operation, a first temperature rise temperature of the room in which the air-conditioning heating operation is performed, that is, a temperature difference between the second room temperature and the first room temperature is calculated according to the first room temperature and the second room temperature.
For example, when the air conditioner starts to operate in a cooling and starting mode, the first room temperature is detected to be T1, the second room temperature is detected to be T2 after the air conditioner operates for a preset time (for example, 60min), and the first temperature drop temperature Δ T1 is T1-T2. For example, when the air conditioner is turned on, the first room temperature is T1, the second room temperature is T2 after the air conditioner is operated for a preset time (for example, 60min), and the first temperature rise temperature Δ T1 is T2-T1. Namely, the first temperature rise temperature or the first temperature fall temperature Δ T1:
room temperature | agent detected after delta T1 ═ room initial temperature-60 min
And step S120, determining whether the refrigerant needs to be supplemented according to the first temperature rise temperature or the first temperature fall temperature.
In some embodiments, in the case of the air conditioner cooling operation, if the first temperature drop temperature is greater than a first preset temperature drop temperature threshold value, it is determined that no supplementary refrigerant is required; and if the first temperature drop temperature is less than or equal to a first preset temperature drop temperature threshold value, determining that the refrigerant needs to be supplemented. That is, after the air conditioner is started to operate for a period of time, if the temperature drop of the room does not achieve the expected effect, the refrigeration effect is insufficient, and the refrigerant needs to be supplemented. The first preset temperature drop threshold value can be tested through experiments, different air conditioner refrigeration effects are different, and the first preset temperature drop threshold value can also be different.
For example, the first preset temperature drop threshold is 15 ℃, when the air conditioner is operated in a refrigerating mode, if the delta T1 is judged to be larger than 15 ℃, the air conditioner is judged to have good operation effect and normal refrigerating capacity, and a refrigerant does not need to be supplemented; if the delta T1 is judged to be less than or equal to 15 ℃, the refrigerating capacity of the air conditioner is judged to be insufficient, and the refrigerant needs to be supplemented.
In some embodiments, in the case of the air conditioner heating operation, if the first temperature rise temperature is greater than a first preset temperature rise temperature threshold, it is determined that a refrigerant does not need to be supplemented; and if the first temperature rise temperature is less than or equal to a first preset temperature rise temperature threshold value, determining that the refrigerant needs to be supplemented. That is, after the air conditioner is turned on and operated for a period of time, if the room temperature rises and does not reach the expected effect, the heating effect is insufficient, and the refrigerant needs to be supplemented. The first preset temperature rise temperature threshold value can be tested through experiments, different air conditioner refrigeration effects are different, and the first preset temperature rise temperature threshold value can also be different.
For example, when the first preset temperature rise temperature threshold is 20 ℃, and the air conditioner is operated for heating, if the delta T1 is judged to be more than 20 ℃, the capacity of the air conditioner is judged to be normal, and the refrigerant does not need to be supplemented; if the delta T1 is judged to be less than or equal to 20 ℃, the heating capacity of the air conditioner is judged to be insufficient, and the refrigerant needs to be supplemented.
And step S130, if the compressor needs to be supplemented with the refrigerant, controlling the hole to be opened so as to supplement the refrigerant to the compressor.
And if the situation that the compressor needs to be supplemented with the refrigerant is determined, controlling the opening and closing of the hole to enable the refrigerant in the liquid storage tank to be flashed into the compressor through the hole to enter a refrigeration or heating cycle.
In some embodiments, the refrigerant replenishment amount is determined based on the first temperature rise temperature or the first temperature fall temperature, wherein:
under the condition of refrigerating operation of the air conditioner, if the first temperature drop temperature is less than or equal to a first preset temperature drop temperature threshold value and greater than a second preset temperature drop temperature threshold value, supplementing part of refrigerant in the liquid storage tank; and if the first temperature drop temperature is less than or equal to a second preset temperature drop temperature threshold and greater than a third preset temperature drop temperature threshold, supplementing all refrigerants in the liquid storage tank. The second preset temperature drop threshold and/or the third preset temperature drop threshold can be tested through experiments, different air conditioner refrigeration effects are different, and the second preset temperature drop threshold and/or the third preset temperature drop threshold can also be different.
For example, the first preset temperature drop threshold value is 15 ℃, the second preset temperature drop threshold value is 8 ℃, if the temperature is more than Delta T1 and is less than or equal to 15 ℃, the refrigeration capacity of the air conditioner is judged to be general, and a small amount of refrigerant needs to be supplemented, then the hole is opened to supplement the refrigerant, wherein the supplement amount is half of the storage amount of the refrigerant in the liquid storage tank. If the temperature is more than 0 ℃ and more than delta T1 and more than or equal to 8 ℃, judging that the refrigerating capacity of the air conditioner is poor, opening the hole, and flashing all the refrigerant stored in the liquid storage tank to the circulation process to perform refrigerating circulation to achieve the expected effect of the air conditioner.
Under the condition of heating operation of the air conditioner, if the first temperature rise temperature is less than or equal to a first preset temperature rise temperature threshold and greater than a second preset temperature rise temperature threshold, supplementing part of refrigerant in the liquid storage tank; and if the first temperature rise temperature is less than or equal to a second preset temperature rise temperature threshold and greater than a third preset temperature rise temperature threshold, supplementing all refrigerants in the liquid storage tank. The second preset temperature rise temperature threshold and/or the third preset temperature rise temperature threshold can be tested through experiments, different air conditioners have different refrigeration effects, and the second preset temperature rise temperature threshold and/or the third preset temperature rise temperature threshold can also be different.
For example, the first preset temperature rise threshold is 20 ℃, the second preset temperature rise threshold is 10 ℃, the third preset temperature rise threshold is 0 ℃, if the temperature is more than delta T1 and less than or equal to 20 ℃, the heating capacity of the air conditioner is judged to be general, a small amount of refrigerant needs to be supplemented, the hole is opened, the refrigerant is supplemented, and the supplement amount is half of the storage amount of the refrigerant in the liquid storage tank. If the temperature is more than 0 ℃ and less than or equal to Delta T1 and less than or equal to 10 ℃, the heating capacity of the air conditioner is judged to be poor, the hole is opened, so that all the refrigerant stored in the liquid storage tank is flashed to the circulation process to carry out refrigeration circulation, and the expected effect of the air conditioner is achieved.
Fig. 3 is a method schematic diagram of another embodiment of the air conditioner control method provided by the invention.
As shown in fig. 3, according to another embodiment of the present invention, the air conditioning control method further includes step S140, step S150, and step S160.
In step S140, in a case where it is determined that a part of the refrigerant in the liquid storage tank is replenished, a second temperature rise temperature (temperature rise value) or a second temperature fall temperature (temperature fall value) of a room in which the refrigerant is present from when the replenishment of the refrigerant is completed to when the replenishment of the refrigerant is completed for a preset time is detected.
If only part of the refrigerant in the liquid storage tank is supplemented to the refrigeration or heating cycle, when the refrigerant supplement is completed, detecting a second temperature rise temperature or a second temperature drop temperature of a room in which the refrigerant is located from the time of completing the refrigerant supplement to the time of completing the refrigerant supplement by a preset time, and judging whether the refrigerant needs to be supplemented again according to the second temperature rise temperature or the second temperature drop temperature.
Specifically, a third room temperature of a room where the refrigerant is filled is detected, a fourth room temperature of the room where the refrigerant is filled is detected after preset time, and a second temperature rise temperature or a second temperature drop temperature of the room where the refrigerant is filled is calculated according to the third room temperature and the fourth room temperature. Under the condition of the air-conditioning cooling operation, calculating a second temperature drop temperature of the room according to the third room temperature and the fourth room temperature, namely a temperature difference value between the third room temperature and the fourth room temperature; and under the condition of heating operation of the air conditioner, calculating a second temperature rise temperature of the room according to the third room temperature and the fourth room temperature, namely calculating a temperature difference value between the fourth room temperature and the third room temperature.
For example, in the case of the air-conditioning cooling operation, when the refrigerant supplement is completed, the third room temperature is detected as T3, the fourth room temperature is detected as T4 after the air-conditioning operation is continued for a preset time (for example, 60min), and the second temperature drop temperature Δ T2 is T4-T3. For example, in the case of the air conditioner heating operation, when the refrigerant supplement is completed, the third room temperature is detected as T3, the fourth room temperature is detected as T4 after the air conditioner continues to operate for a preset time (for example, 60min), and the second temperature drop temperature Δ T2 is T3-T4. Namely, the second temperature rise temperature or the second temperature fall temperature Δ T2:
temperature detected after delta T2 ═ operation for 60 min-room temperature | detected after refrigerant is added and operation for 60min
And step S150, determining whether the refrigerant needs to be replenished again according to the second temperature rise temperature or the second temperature fall temperature.
Under the condition of refrigerating operation of the air conditioner, if the first temperature drop temperature is greater than a fourth preset temperature drop temperature threshold value, determining that the refrigerant does not need to be supplemented again; and if the first temperature drop temperature is less than or equal to a fourth preset temperature drop temperature threshold value, determining that the refrigerant needs to be supplemented again. The fourth preset temperature drop threshold value can be tested through experiments, different air conditioner refrigeration effects are different, and the fourth preset temperature drop threshold value can also be different.
For example, when the fourth predetermined temperature drop threshold is 7 ℃, during the air-conditioning cooling operation, if Δ T2 is greater than 7 ℃, it can be determined that the refrigerant flow is properly added, and if 0 ℃ < Δt2 ≦ 7 ℃, the remaining refrigerant needs to be supplemented.
Under the condition of heating operation of the air conditioner, if the first temperature rise temperature is greater than a fourth preset temperature rise temperature threshold value, determining that the refrigerant does not need to be supplemented again; and if the first temperature rise temperature is less than or equal to a fourth preset temperature rise temperature threshold value, determining that the refrigerant needs to be supplemented again. The fourth preset temperature rise temperature threshold value can be tested through experiments, different air conditioner refrigeration effects are different, and the fourth preset temperature rise temperature threshold value can also be different.
For example, when the fourth preset temperature rise threshold is 10 ℃, during the heating operation of the air conditioner, if Δ T2 is greater than 10 ℃, it can be determined that the refrigerant flow is properly added, and if 0 ℃ < Δt2 ≦ 10 ℃, the surplus refrigerant needs to be supplemented.
And step S160, if the refrigerant needs to be replenished again, controlling the hole to be opened so as to replenish the refrigerant to the compressor.
And if the refrigerant needs to be replenished again, controlling the switch of the hole to be opened, so that the refrigerant in the liquid storage tank is flashed and replenished into the compressor through the hole, and entering a refrigeration or heating cycle.

TABLE 2
Fig. 6 is a block diagram of an embodiment of an air conditioning control apparatus according to the present invention. As shown in fig. 6, the air conditioning control device 100 includes a detection unit 110, a determination unit 120, and a control unit 130.
The detecting unit 110 is configured to detect a first temperature rise temperature (a temperature rise value) or a first temperature drop temperature (a temperature drop value) of a room from when the air conditioner starts to operate to when the air conditioner operates for a preset time after the air conditioner is started.
Detecting a first room temperature of a room where the air conditioner starts to operate and a second room temperature of the room where the air conditioner operates after a preset time, and calculating a first temperature rise temperature or a first temperature drop temperature of the room according to the first room temperature and the second room temperature. Under the condition of the cooling operation of the air conditioner, calculating a first temperature drop temperature of the room according to the first room temperature and the second room temperature, namely a temperature difference value between the first room temperature and the second room temperature; in the case of the air-conditioning heating operation, a first temperature rise temperature of the room in which the air-conditioning heating operation is performed, that is, a temperature difference between the second room temperature and the first room temperature is calculated according to the first room temperature and the second room temperature.
For example, when the air conditioner starts to operate in a cooling and starting mode, the first room temperature is detected to be T1, the second room temperature is detected to be T2 after the air conditioner operates for a preset time (for example, 60min), and the first temperature drop temperature Δ T1 is T1-T2. For example, when the air conditioner is turned on, the first room temperature is T1, the second room temperature is T2 after the air conditioner is operated for a preset time (for example, 60min), and the first temperature rise temperature Δ T1 is T2-T1. Namely, the first temperature rise temperature or the first temperature fall temperature Δ T1:
room temperature | agent detected after delta T1 ═ room initial temperature-60 min
The determination unit 120 is configured to determine whether the refrigerant needs to be supplemented according to the first temperature-rising temperature or the first temperature-falling temperature.
In some embodiments, in the case of the air conditioner cooling operation, if the first temperature drop temperature is greater than a first preset temperature drop temperature threshold value, it is determined that no supplementary refrigerant is required; and if the first temperature drop temperature is less than or equal to a first preset temperature drop temperature threshold value, determining that the refrigerant needs to be supplemented. That is, after the air conditioner is started to operate for a period of time, if the temperature drop of the room does not achieve the expected effect, the refrigeration effect is insufficient, and the refrigerant needs to be supplemented. The first preset temperature drop threshold value can be tested through experiments, different air conditioner refrigeration effects are different, and the first preset temperature drop threshold value can also be different.
For example, the first preset temperature drop threshold is 15 ℃, when the air conditioner is operated in a refrigerating mode, if the delta T1 is judged to be larger than 15 ℃, the air conditioner is judged to have good operation effect and normal refrigerating capacity, and a refrigerant does not need to be supplemented; if the delta T1 is judged to be less than or equal to 15 ℃, the refrigerating capacity of the air conditioner is judged to be insufficient, and the refrigerant needs to be supplemented.
In some embodiments, in the case of the air conditioner heating operation, if the first temperature rise temperature is greater than a first preset temperature rise temperature threshold, it is determined that a refrigerant does not need to be supplemented; and if the first temperature rise temperature is less than or equal to a first preset temperature rise temperature threshold value, determining that the refrigerant needs to be supplemented. That is, after the air conditioner is turned on and operated for a period of time, if the room temperature rises and does not reach the expected effect, the heating effect is insufficient, and the refrigerant needs to be supplemented. The first preset temperature rise temperature threshold value can be tested through experiments, different air conditioner refrigeration effects are different, and the first preset temperature rise temperature threshold value can also be different.
For example, when the first preset temperature rise temperature threshold is 20 ℃, and the air conditioner is operated for heating, if the delta T1 is judged to be more than 20 ℃, the capacity of the air conditioner is judged to be normal, and the refrigerant does not need to be supplemented; if the delta T1 is judged to be less than or equal to 20 ℃, the heating capacity of the air conditioner is judged to be insufficient, and the refrigerant needs to be supplemented.
The control unit 130 is configured to control the orifice to be opened to supplement the refrigerant to the compressor if the determination unit 120 determines that the supplement of the refrigerant is required. And if the situation that the compressor needs to be supplemented with the refrigerant is determined, controlling the opening and closing of the hole to enable the refrigerant in the liquid storage tank to be flashed into the compressor through the hole to enter a refrigeration or heating cycle.
In some embodiments, the determining unit 120 is further configured to: if the fact that the refrigerant needs to be supplemented is determined, determining the supplement amount of the refrigerant according to the first temperature-rising temperature or the first temperature-falling temperature, wherein:
under the condition of refrigerating operation of the air conditioner, if the first temperature drop temperature is less than or equal to a first preset temperature drop temperature threshold value and greater than a second preset temperature drop temperature threshold value, supplementing part of refrigerant in the liquid storage tank; and if the first temperature drop temperature is less than or equal to a second preset temperature drop temperature threshold and greater than a third preset temperature drop temperature threshold, supplementing all refrigerants in the liquid storage tank. The second preset temperature drop threshold and/or the third preset temperature drop threshold can be tested through experiments, different air conditioner refrigeration effects are different, and the second preset temperature drop threshold and/or the third preset temperature drop threshold can also be different.
For example, the first preset temperature drop threshold value is 15 ℃, the second preset temperature drop threshold value is 8 ℃, if the temperature is more than Delta T1 and is less than or equal to 15 ℃, the refrigeration capacity of the air conditioner is judged to be general, and a small amount of refrigerant needs to be supplemented, then the hole is opened to supplement the refrigerant, wherein the supplement amount is half of the storage amount of the refrigerant in the liquid storage tank. If the temperature is more than 0 ℃ and more than delta T1 and more than or equal to 8 ℃, judging that the refrigerating capacity of the air conditioner is poor, opening the hole, and flashing all the refrigerant stored in the liquid storage tank to the circulation process to perform refrigerating circulation to achieve the expected effect of the air conditioner.
Under the condition of heating operation of the air conditioner, if the first temperature rise temperature is less than or equal to a first preset temperature rise temperature threshold and greater than a second preset temperature rise temperature threshold, supplementing part of refrigerant in the liquid storage tank; and if the first temperature rise temperature is less than or equal to a second preset temperature rise temperature threshold and greater than a third preset temperature rise temperature threshold, supplementing all refrigerants in the liquid storage tank. The second preset temperature rise temperature threshold and/or the third preset temperature rise temperature threshold can be tested through experiments, different air conditioners have different refrigeration effects, and the second preset temperature rise temperature threshold and/or the third preset temperature rise temperature threshold can also be different.
For example, the first preset temperature rise threshold is 20 ℃, the second preset temperature rise threshold is 10 ℃, the third preset temperature rise threshold is 0 ℃, if the temperature is more than delta T1 and less than or equal to 20 ℃, the heating capacity of the air conditioner is judged to be general, a small amount of refrigerant needs to be supplemented, the hole is opened, the refrigerant is supplemented, and the supplement amount is half of the storage amount of the refrigerant in the liquid storage tank. If the temperature is more than 0 ℃ and less than or equal to Delta T1 and less than or equal to 10 ℃, the heating capacity of the air conditioner is judged to be poor, the hole is opened, so that all the refrigerant stored in the liquid storage tank is flashed to the circulation process to carry out refrigeration circulation, and the expected effect of the air conditioner is achieved.
In some embodiments, in the case that it is determined to replenish a portion of the refrigerant in the receiver tank, the detection unit 110 is further configured to: a second temperature increase temperature (temperature increase value) or a second temperature decrease temperature (temperature decrease value) of a room in which the refrigerant supplement is completed to a preset time from the completion of the refrigerant supplement is detected.
If only part of the refrigerant in the liquid storage tank is supplemented to the refrigeration or heating cycle, when the refrigerant supplement is completed, detecting a second temperature rise temperature or a second temperature drop temperature of a room in which the refrigerant is located from the time of completing the refrigerant supplement to the time of completing the refrigerant supplement by a preset time, and judging whether the refrigerant needs to be supplemented again according to the second temperature rise temperature or the second temperature drop temperature.
Specifically, the detection unit 110 detects a third room temperature of a room where the refrigerant supplement is completed, detects a fourth room temperature of the room where the refrigerant supplement is completed for a preset time, and calculates a second temperature increase temperature or a second temperature decrease temperature of the room where the refrigerant supplement is completed according to the third room temperature and the fourth room temperature. Under the condition of the air-conditioning cooling operation, calculating a second temperature drop temperature of the room according to the third room temperature and the fourth room temperature, namely a temperature difference value between the third room temperature and the fourth room temperature; and under the condition of heating operation of the air conditioner, calculating a second temperature rise temperature of the room according to the third room temperature and the fourth room temperature, namely calculating a temperature difference value between the fourth room temperature and the third room temperature.
For example, in the case of the air-conditioning cooling operation, when the refrigerant supplement is completed, the third room temperature is detected as T3, the fourth room temperature is detected as T4 after the air-conditioning operation is continued for a preset time (for example, 60min), and the second temperature drop temperature Δ T2 is T4-T3. For example, in the case of the air conditioner heating operation, when the refrigerant supplement is completed, the third room temperature is detected as T3, the fourth room temperature is detected as T4 after the air conditioner continues to operate for a preset time (for example, 60min), and the second temperature drop temperature Δ T2 is T3-T4. Namely, the second temperature rise temperature or the second temperature fall temperature Δ T2:
temperature detected after delta T2 ═ operation for 60 min-room temperature | detected after operation for 60min after refrigerant is added
The determining unit 120 is further configured to: and determining whether the compressor needs to be supplemented with the refrigerant again according to the second temperature rise temperature or the second temperature fall temperature.

The fourth preset temperature drop threshold value can be tested through experiments, different air conditioner refrigeration effects are different, and the fourth preset temperature drop threshold value can also be different.
For example, when the fourth predetermined temperature drop threshold is 7 ℃, during the air-conditioning cooling operation, if Δ T2 is greater than 7 ℃, it can be determined that the refrigerant flow is properly added, and if 0 ℃ < Δt2 ≦ 7 ℃, the remaining refrigerant needs to be supplemented.
Under the condition of heating operation of the air conditioner, if the first temperature rise temperature is greater than a fourth preset temperature rise temperature threshold value, determining that the refrigerant does not need to be supplemented again; and if the first temperature rise temperature is less than or equal to a fourth preset temperature rise temperature threshold value, determining that the refrigerant needs to be supplemented again. The fourth preset temperature rise temperature threshold value can be tested through experiments, different air conditioner refrigeration effects are different, and the fourth preset temperature rise temperature threshold value can also be different.
