[0033] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0034] The air conditioner of the present invention performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0035] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0036] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-temperature and low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0037] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0038] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0039] Reference below Figure 1-Figure 5 An air conditioner 1 according to an embodiment of the present invention will be described.

[0040] like Figure 1 As shown, the air conditioner 1 of the embodiment of the present invention comprises: a compressor 11, an indoor environment temperature sensor 12, an indoor coil temperature sensor 13, an outdoor environment temperature sensor 14, an outdoor coil temperature sensor 15 and a controller 16, wherein:

[0042] In the embodiment, after the air conditioner 1 is turned on and operated, the controller 16 obtains the operating parameters of the air conditioner 1 in real time when it is in an operating state, including obtaining the power value of the air conditioner 1, for example, recorded as P, and the frequency value of the compressor 11; obtaining the operating mode of the air conditioner 1, and the operating mode includes, for example, a heating mode and a cooling mode, etc.; obtaining the indoor ambient temperature according to the indoor ambient temperature sensor 12, for example, recorded as Tindoor, obtaining the indoor coil temperature according to the indoor coil temperature sensor 13, for example, recorded as Tincoil, obtaining the outdoor ambient temperature according to the outdoor ambient temperature sensor 14, for example, recorded as Toutdoor, and obtaining the outdoor coil temperature according to the outdoor coil temperature sensor 15, for example, recorded as Toutcoil.

[0043] After obtaining the above-mentioned operating parameters, the capacity calculation formula of the air conditioner 1 is used and combined with the above-mentioned operating parameters to determine the capacity of the air conditioner 1 corresponding to different operating modes. For example, when the operating mode of the air conditioner 1 is in the cooling operation mode, the capacity calculation formula of the air conditioner 1 is used and combined with the above-mentioned operating parameters to determine the cooling capacity of the air conditioner 1; when the operating mode of the air conditioner 1 is in the heating operation mode, the capacity calculation formula of the air conditioner 1 is used and combined with the above-mentioned parameters to determine the heating capacity of the air conditioner 1.

[0044] According to the air conditioner 1 of the embodiment of the present invention, after being turned on and running, the operating parameters of the air conditioner 1 in the operating state are obtained in real time, including power value, operating mode, indoor ambient temperature, indoor coil temperature, outdoor ambient temperature, outdoor coil temperature and frequency value of the compressor 11, and the capacity calculation formula of the air conditioner 1 is used to calculate the real-time capacity of the air conditioner 1 in the current operating mode, that is, the cooling capacity or heating capacity of the air conditioner 1 is measured in real time. By using the capacity calculation formula of the air conditioner 1 to calculate the real-time capacity, there is no need to calculate the capacity of the air conditioner 1 according to the enthalpy difference method, so that the capacity calculation of the air conditioner 1 is more convenient and accurate, and there is no need to realize the capacity detection of the air conditioner 1 by adding additional devices, thereby reducing the hardware space occupied by the air conditioner 1 and reducing the hardware cost.

[0045] In some embodiments, when the cooling capacity or heating capacity of the air conditioner 1 in the current operating mode is obtained according to the power value of the air conditioner 1, the operating mode of the air conditioner 1, the indoor ambient temperature, the indoor coil temperature, the outdoor ambient temperature, the outdoor coil temperature, the frequency value of the compressor 11 and the capacity calculation formula of the air conditioner 1, the controller 16 is configured to: obtain the operating mode correction coefficient corresponding to the operating mode of the air conditioner 1, the indoor temperature correction coefficient corresponding to the indoor ambient temperature and the indoor coil temperature, the outdoor temperature correction coefficient corresponding to the outdoor ambient temperature and the outdoor coil temperature, and the frequency correction coefficient corresponding to the frequency value of the compressor 11; obtain the energy efficiency value of the air conditioner 1 in the current operating mode according to the operating mode of the air conditioner 1, the indoor ambient temperature, the indoor coil temperature, the outdoor ambient temperature, the outdoor coil temperature, the frequency value of the compressor 11, the indoor temperature correction coefficient, the outdoor temperature correction coefficient, the frequency correction coefficient and the operating mode correction coefficient; substitute the energy efficiency value and the power value into the capacity calculation formula of the air conditioner 1 to obtain the cooling capacity or heating capacity of the air conditioner 1 in the current operating mode.

[0046] In an embodiment, after obtaining the power value P of the air conditioner 1, the operating mode of the air conditioner 1, the indoor ambient temperature Tindoor, the indoor coil temperature Tincoil, the outdoor ambient temperature Toutdoor, the outdoor coil temperature Toutcoil and the frequency value of the compressor 11, the controller 16 obtains the operating mode correction coefficient corresponding to the operating mode of the air conditioner 1 based on engineering test experience, for example, recorded as D, and the operating mode correction coefficient D is a constant. When the operating mode of the air conditioner 1 is in the cooling operation mode, the cooling capacity is the difference between the heat exchange heat of the outdoor unit and the work heat of the refrigerant compressed by the compressor 11; when the operating mode of the air conditioner 1 is in the heating operation mode, the heating capacity is the sum of the heat exchange heat of the outdoor unit and the work heat of the refrigerant compressed by the compressor 11. Therefore, the heating energy efficiency is usually greater than the cooling energy efficiency. When calculating the energy efficiency value of the air conditioner 1, the operating mode correction coefficient D is required for mode correction.

[0047] Based on engineering test experience, the controller 16 obtains the indoor temperature correction coefficient corresponding to the indoor ambient temperature Tindoor and the indoor coil temperature Tincoil, for example, recorded as A, and the indoor temperature correction coefficient A is a constant; obtains the outdoor temperature correction coefficient corresponding to the outdoor ambient temperature Toutdoor and the outdoor coil temperature Toutcoil, for example, recorded as B, and the outdoor temperature correction coefficient B is a constant; obtains the frequency correction coefficient corresponding to the frequency value of the compressor 11, for example, recorded as C, and the frequency correction coefficient C is a constant. When the heat exchange area of ​​the indoor unit and the outdoor unit is constant, if the circulation flow rate is larger, the heat dissipation efficiency of the heat exchanger is lower, and the energy efficiency value of the air conditioner 1 is lower, when calculating the energy efficiency value of the air conditioner 1, the frequency correction coefficient C is required for frequency correction.

[0048] After obtaining the indoor temperature correction coefficient A, the outdoor temperature correction coefficient B, the frequency correction coefficient C and the operation mode correction coefficient D, the energy efficiency value of the air conditioner 1 in the current operation mode is obtained according to the operation mode of the air conditioner 1, the indoor ambient temperature Tindoor, the indoor coil temperature Tincoil, the outdoor ambient temperature Toutdoor, the outdoor coil temperature Toutcoil, the frequency value of the compressor 11 and the above correction parameters, for example, recorded as EER, and the energy efficiency value EER and the power value P are substituted into the capacity calculation formula of the air conditioner 1 to obtain the real-time capacity of the air conditioner 1 in the current operation mode, for example, recorded as Q, that is, the cooling capacity or heating capacity of the air conditioner is measured in real time.

[0049] In some embodiments, when the energy efficiency value of the air conditioner 1 in the current operating mode is obtained according to the operating mode of the air conditioner 1, the indoor ambient temperature, the indoor coil temperature, the outdoor ambient temperature, the outdoor coil temperature, the frequency value of the compressor 11, the indoor temperature correction coefficient, the outdoor temperature correction coefficient, the frequency correction coefficient and the operating mode correction coefficient, the controller 16 is configured as follows: performing temperature correction on the indoor ambient temperature and the indoor coil temperature according to the indoor temperature correction coefficient to obtain the indoor temperature correction value; performing temperature correction on the outdoor ambient temperature and the outdoor coil temperature according to the outdoor temperature correction coefficient to obtain the outdoor temperature correction value; performing frequency correction on the frequency value of the compressor 11 according to the frequency correction coefficient to obtain the frequency correction value; correcting the operating mode of the air conditioner 1 according to the operating mode correction coefficient to obtain the operating mode correction value; obtaining the energy efficiency value of the air conditioner 1 in the current operating mode according to the indoor temperature correction value, the outdoor temperature correction value, the frequency correction value, the operating mode correction value and the energy efficiency calculation formula of the air conditioner 1.

[0050] In an embodiment, Figure 2As shown, it is a flow chart of a method for calculating the energy efficiency value of an air conditioner according to an embodiment of the present invention. After obtaining the indoor temperature correction coefficient A, the outdoor temperature correction coefficient B, the frequency correction coefficient C and the operation mode correction coefficient D, the indoor environment temperature Tindoor and the indoor coil temperature Tincoil are temperature-corrected according to the indoor temperature correction coefficient A to obtain the outdoor temperature correction value; the outdoor environment temperature Toutdoor and the outdoor coil temperature Toutcoil are temperature-corrected according to the outdoor temperature correction coefficient B to obtain the outdoor temperature correction value; the frequency value of the compressor 11 is frequency-corrected according to the frequency correction coefficient C to obtain the frequency correction value; the operation mode of the air conditioner 1 is corrected according to the operation mode correction coefficient D to obtain the operation mode correction value; the indoor temperature correction value, the outdoor temperature correction value, the frequency correction value and the operation mode correction value are brought into the energy efficiency calculation formula of the air conditioner 1 to obtain the energy efficiency value EER of the air conditioner 1 under the current operation mode, thereby calculating the cooling capacity or heating capacity Q of the air conditioner 1.

[0051] In some embodiments, when the indoor ambient temperature and the indoor coil temperature are corrected according to the indoor temperature correction coefficient to obtain the indoor temperature correction value, the controller 16 is configured to: calculate the temperature difference between the indoor ambient temperature and the indoor coil temperature to obtain the absolute value of the indoor temperature difference; and correct the absolute value of the indoor temperature difference according to the indoor temperature correction coefficient to obtain the indoor temperature correction value.

[0052] In an embodiment, Figure 3 As shown, it is a flow chart of a method for calculating the indoor temperature correction value of an air conditioner according to an embodiment of the present invention. After obtaining the indoor ambient temperature Tindoor and the indoor coil temperature Tincoil, the temperature difference between the indoor ambient temperature Tindoor and the indoor coil temperature Tincoil is calculated and the absolute value is taken, that is, the absolute value of the indoor temperature difference is |Tindoor-Tincoil|, and the absolute value of the indoor temperature difference |Tindoor-Tincoil| is corrected according to the indoor temperature correction coefficient A to obtain the indoor temperature correction value, that is, |Tindoor-Tincoil|×A. It can be understood that according to the heat transfer formula of an object Q=c×m×△T, the greater the heat exchange temperature difference between two objects, the higher the heat exchange amount. Therefore, when the temperature difference between the indoor ambient temperature Tindoor and the indoor coil temperature Tincoil is greater, the energy efficiency value EER of the air conditioner 1 is greater.

[0053] In some embodiments, when the outdoor ambient temperature and the outdoor coil temperature are corrected according to the outdoor temperature correction coefficient to obtain the outdoor temperature correction value, the controller 16 is configured to: calculate the temperature difference between the outdoor ambient temperature and the outdoor coil temperature to obtain the absolute value of the outdoor temperature difference; and correct the absolute value of the outdoor temperature difference according to the outdoor temperature correction coefficient to obtain the outdoor temperature correction value.

[0054] In an embodiment, Figure 4 As shown, it is a flow chart of a method for calculating the outdoor temperature correction value of an air conditioner according to an embodiment of the present invention. After obtaining the outdoor ambient temperature Toutdoor and the outdoor coil temperature Toutcoil, the temperature difference between the outdoor ambient temperature Toutdoor and the outdoor coil temperature Toutcoil is calculated and the absolute value is taken, that is, the absolute value of the outdoor temperature difference is |Toutdoor-Toutcoil|, and the absolute value of the outdoor temperature difference |Toutdoor-Toutcoil| is corrected according to the outdoor temperature correction coefficient B to obtain the outdoor temperature correction value, that is, |Toutdoor-Toutcoil|×B. It can be understood that according to the heat transfer formula of an object Q=c×m×△T, the greater the heat exchange temperature difference between two objects, the higher the heat exchange amount. Therefore, when the temperature difference between the outdoor ambient temperature Toutdoor and the outdoor coil temperature Toutcoil is greater, the energy efficiency value EER of the air conditioner 1 is greater.

[0055] In some embodiments, the energy efficiency calculation formula of the air conditioner 1 includes:

[0056] EER=

|Tindoor-Tincoil|×A+|Toutdoor-Toutcoil|×B+C

[0057] Among them, EER is the energy efficiency value of air conditioner 1, Tindoor is the indoor ambient temperature, Tincoil is the indoor coil temperature, A is the indoor temperature correction coefficient, Toutdoor is the outdoor ambient temperature, Toutcoil is the outdoor coil temperature, B is the outdoor temperature correction coefficient, C is the frequency correction coefficient, and D is the operation mode correction coefficient.

[0058] In the embodiment, after determining the indoor temperature correction value, i.e., |Tindoor-Tincoil|×A, and the outdoor temperature correction value, i.e., |Toutdoor-Toutcoil|×B, the above parameters are combined with the frequency correction coefficient C and the operation mode correction coefficient D and brought into the energy efficiency calculation formula of the air conditioner 1. The energy efficiency calculation formula of the air conditioner 1 is as follows:

[0059] EER=

|Tindoor-Tincoil|×A+|Toutdoor-Toutcoil|×B+C

[0060] By calculating the energy efficiency value EER of the air conditioner 1, the cooling capacity or heating capacity Q of the air conditioner 1 in the current operation mode of the air conditioner 1 is calculated according to the energy efficiency value EER, so as to measure the capacity of the air conditioner 1 in real time under different operation modes.

[0061] In some embodiments, the capability calculation formula includes:

[0062] Q=P×EER

[0063] Wherein, Q is the cooling capacity or heating capacity of the air conditioner 1 , P is the power value of the air conditioner 1 , and EER is the energy efficiency value of the air conditioner 1 .

[0064] In the embodiment, after determining the energy efficiency value EER and the power value P of the air conditioner 1, the above parameters are substituted into the capacity calculation formula of the air conditioner 1. The capacity calculation formula of the air conditioner 1 is as follows:

[0065] Q=P×EER

[0066] By calculating the real-time capacity Q of the air conditioner 1 according to the energy efficiency value EER and the power value P of the air conditioner 1, the heating amount when the operation mode of the air conditioner 1 is in the heating operation mode; and the cooling capacity when the operation mode of the air conditioner 1 is in the cooling operation mode are determined.

[0067] In some embodiments, after determining the cooling capacity or heating capacity of the air conditioner 1 in the current operating mode, the controller 16 is further configured to: send the cooling capacity or heating capacity of the air conditioner 1 to the user terminal and / or the display screen of the air conditioner 1.

[0068] In an embodiment, after determining the cooling capacity or heating capacity of the air conditioner 1 in the current operating mode, the controller 16 sends the cooling capacity or heating capacity to a user terminal such as a mobile phone APP, and / or sends it to the display screen of the air conditioner 1 for display, so that the user can understand the real-time status of the air conditioner 1.

Among them, the compressor is used to compress the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure refrigerant gas and discharge it to the condenser; the indoor ambient temperature sensor is used to detect the indoor ambient temperature in real time; the indoor coil temperature sensor is used to detect the indoor coil temperature in real time; the outdoor ambient temperature sensor is used to detect the outdoor ambient temperature in real time; and the outdoor coil temperature sensor is used to detect the outdoor coil temperature in real time.

[0087] Step S2, obtaining the cooling capacity or heating capacity of the air conditioner in the current operating mode according to the power value of the air conditioner, the operating mode of the air conditioner, the indoor ambient temperature, the indoor coil temperature, the outdoor ambient temperature, the outdoor coil temperature, the frequency value of the compressor and the capacity calculation formula of the air conditioner.

[0088] In an embodiment, after obtaining the above-mentioned operating parameters, the capacity calculation formula of the air conditioner is used and combined with the above-mentioned operating parameters to determine the capacity of the air conditioner corresponding to different operating modes. For example, when the operating mode of the air conditioner is in the cooling operating mode, the capacity calculation formula of the air conditioner is used and combined with the above-mentioned operating parameters to determine the cooling capacity of the air conditioner; when the operating mode of the air conditioner is in the heating operating mode, the capacity calculation formula of the air conditioner is used and combined with the above-mentioned parameters to determine the heating capacity of the air conditioner.

[0089] According to the capacity calculation method of the air conditioner according to the embodiment of the present invention, after the air conditioner is turned on and operated, the operating parameters of the air conditioner in the operating state are obtained in real time, including power value, operating mode, indoor ambient temperature, indoor coil temperature, outdoor ambient temperature, outdoor coil temperature and frequency value of the compressor, and the capacity calculation formula of the air conditioner is used to calculate the real-time capacity of the air conditioner in the current operating mode, that is, the cooling capacity or heating capacity of the air conditioner is measured in real time. By using the capacity calculation formula of the air conditioner to calculate the real-time capacity, there is no need to calculate the capacity of the air conditioner according to the enthalpy difference method, so that the capacity calculation of the air conditioner is more convenient and accurate, and there is no need to realize the capacity detection of the air conditioner by adding additional devices, thereby reducing the hardware cost while reducing the hardware space occupied by the air conditioner.

[0090] In some embodiments, the cooling capacity or heating capacity of the air conditioner in the current operating mode is obtained according to the power value of the air conditioner, the operating mode of the air conditioner, the indoor ambient temperature, the indoor coil temperature, the outdoor ambient temperature, the outdoor coil temperature, the frequency value of the compressor and the capacity calculation formula of the air conditioner, including: obtaining the operating mode correction coefficient corresponding to the operating mode of the air conditioner, the indoor temperature correction coefficient corresponding to the indoor ambient temperature and the indoor coil temperature, the outdoor temperature correction coefficient corresponding to the outdoor ambient temperature and the outdoor coil temperature, and the frequency correction coefficient corresponding to the frequency value of the compressor; obtaining the energy efficiency value of the air conditioner in the current operating mode according to the operating mode of the air conditioner, the indoor ambient temperature, the indoor coil temperature, the outdoor ambient temperature, the outdoor coil temperature, the frequency value of the compressor, the indoor temperature correction coefficient, the outdoor temperature correction coefficient, the frequency correction coefficient and the operating mode correction coefficient; substituting the energy efficiency value and the power value into the capacity calculation formula of the air conditioner to obtain the cooling capacity or heating capacity of the air conditioner in the current operating mode.

[0091] In an embodiment, after obtaining the power value P of the air conditioner, the operating mode of the air conditioner, the indoor ambient temperature Tindoor, the indoor coil temperature Tincoil, the outdoor ambient temperature Toutdoor, the outdoor coil temperature Toutcoil and the frequency value of the compressor, the controller obtains the operating mode correction coefficient corresponding to the operating mode of the air conditioner based on engineering test experience, for example, recorded as D. The operating mode correction coefficient D is a constant. When the operating mode of the air conditioner is in the cooling operating mode, the cooling capacity is the difference between the heat exchange heat of the outdoor unit and the work heat of the compressor compressing the refrigerant; when the operating mode of the air conditioner is in the heating operating mode, the heating capacity is the sum of the heat exchange heat of the outdoor unit and the work heat of the compressor compressing the refrigerant. Therefore, the heating energy efficiency is usually greater than the cooling energy efficiency. When calculating the energy efficiency value of the air conditioner, the operating mode correction coefficient D is required to perform mode correction.

[0092] According to engineering test experience, the controller obtains the indoor temperature correction coefficient corresponding to the indoor ambient temperature Tindoor and the indoor coil temperature Tincoil, for example, recorded as A, and the indoor temperature correction coefficient A is a constant; obtains the outdoor temperature correction coefficient corresponding to the outdoor ambient temperature Toutdoor and the outdoor coil temperature Toutcoil, for example, recorded as B, and the outdoor temperature correction coefficient B is a constant; obtains the frequency correction coefficient corresponding to the frequency value of the compressor, for example, recorded as C, and the frequency correction coefficient C is a constant. When the heat exchange area of ​​the indoor unit and the outdoor unit is constant, if the circulation flow rate is larger, the heat dissipation efficiency of the heat exchanger is lower, and the energy efficiency value of the air conditioner is lower, when calculating the energy efficiency value of the air conditioner, the frequency correction coefficient C is required for frequency correction.

[0093] After obtaining the indoor temperature correction coefficient A, the outdoor temperature correction coefficient B, the frequency correction coefficient C and the operation mode correction coefficient D, the energy efficiency value of the air conditioner 1 in the current operation mode is obtained according to the operation mode of the air conditioner 1, the indoor ambient temperature Tindoor, the indoor coil temperature Tincoil, the outdoor ambient temperature Toutdoor, the outdoor coil temperature Toutcoil, the frequency value of the compressor 11 and the above correction parameters, for example, recorded as EER, and the energy efficiency value EER and the power value P are substituted into the capacity calculation formula of the air conditioner 1 to obtain the real-time capacity of the air conditioner 1 in the current operation mode, for example, recorded as Q, that is, the cooling capacity or heating capacity of the air conditioner is measured in real time.

[0094] In some embodiments, when obtaining the energy efficiency value of the air conditioner in the current operating mode according to the operating mode of the air conditioner, indoor ambient temperature, indoor coil temperature, outdoor ambient temperature, outdoor coil temperature, frequency value of the compressor, indoor temperature correction coefficient, outdoor temperature correction coefficient, frequency correction coefficient and operating mode correction coefficient, it includes: performing temperature correction on the indoor ambient temperature and the indoor coil temperature according to the indoor temperature correction coefficient to obtain the indoor temperature correction value; performing temperature correction on the outdoor ambient temperature and the outdoor coil temperature according to the outdoor temperature correction coefficient to obtain the outdoor temperature correction value; performing frequency correction on the frequency value of the compressor according to the frequency correction coefficient to obtain the frequency correction value; correcting the operating mode of the air conditioner according to the operating mode correction coefficient to obtain the operating mode correction value; obtaining the energy efficiency value of the air conditioner in the current operating mode according to the indoor temperature correction value, the outdoor temperature correction value, the frequency correction value, the operating mode correction value and the air conditioner energy efficiency calculation formula.

[0095] In the embodiment, after obtaining the indoor temperature correction coefficient A, the outdoor temperature correction coefficient B, the frequency correction coefficient C and the operation mode correction coefficient D, the indoor ambient temperature Tindoor and the indoor coil temperature Tincoil are temperature corrected according to the indoor temperature correction coefficient A to obtain the outdoor temperature correction value; the outdoor ambient temperature Toutdoor and the outdoor coil temperature Toutcoil are temperature corrected according to the outdoor temperature correction coefficient B to obtain the outdoor temperature correction value; the frequency value of the compressor is frequency corrected according to the frequency correction coefficient C to obtain the frequency correction value; the operation mode of the air conditioner is corrected according to the operation mode correction coefficient D to obtain the operation mode correction value; the indoor temperature correction value, the outdoor temperature correction value, the frequency correction value and the operation mode correction value are substituted into the air conditioner energy efficiency calculation formula to obtain the energy efficiency value EER of the air conditioner under the current operation mode, thereby calculating the cooling capacity or heating capacity Q of the air conditioner 1.

[0096] In some embodiments, when the indoor ambient temperature and the indoor coil temperature are corrected according to the indoor temperature correction coefficient to obtain the indoor temperature correction value, it includes: calculating the temperature difference between the indoor ambient temperature and the indoor coil temperature to obtain the absolute value of the indoor temperature difference; correcting the absolute value of the indoor temperature difference according to the indoor temperature correction coefficient to obtain the indoor temperature correction value.

[0097] In the embodiment, after obtaining the indoor ambient temperature Tindoor and the indoor coil temperature Tincoil, the temperature difference between the indoor ambient temperature Tindoor and the indoor coil temperature Tincoil is calculated and the absolute value is taken, that is, the absolute value of the indoor temperature difference is |Tindoor-Tincoil|, and the absolute value of the indoor temperature difference |Tindoor-Tincoil| is corrected according to the indoor temperature correction coefficient A to obtain the indoor temperature correction value, that is, |Tindoor-Tincoil|×A. It can be understood that according to the heat transfer formula of an object Q=c×m×△T, the greater the heat exchange temperature difference between two objects, the higher the heat exchange amount. Therefore, when the temperature difference between the indoor ambient temperature Tindoor and the indoor coil temperature Tincoil is greater, the energy efficiency value EER of the air conditioner is greater.

[0098] In some embodiments, when the outdoor ambient temperature and the outdoor coil temperature are corrected according to the outdoor temperature correction coefficient to obtain the outdoor temperature correction value, it includes: calculating the temperature difference between the outdoor ambient temperature and the outdoor coil temperature to obtain the absolute value of the outdoor temperature difference; correcting the absolute value of the outdoor temperature difference according to the outdoor temperature correction coefficient to obtain the outdoor temperature correction value.

[0099] In the embodiment, after obtaining the outdoor ambient temperature Toutdoor and the outdoor coil temperature Toutcoil, the temperature difference between the outdoor ambient temperature Toutdoor and the outdoor coil temperature Toutcoil is calculated and the absolute value is taken, that is, the absolute value of the outdoor temperature difference is |Toutdoor-Toutcoil|, and the absolute value of the outdoor temperature difference |Toutdoor-Toutcoil| is corrected according to the outdoor temperature correction coefficient B to obtain the outdoor temperature correction value, that is, |Toutdoor-Toutcoil|×B. It can be understood that according to the heat transfer formula of the object Q=c×m×△T, the greater the heat exchange temperature difference between the two objects, the higher the heat exchange amount. Therefore, when the temperature difference between the outdoor ambient temperature Toutdoor and the outdoor coil temperature Toutcoil is greater, the energy efficiency value EER of the air conditioner is greater.

[0100] In some embodiments, the air conditioner energy efficiency calculation formula includes:

[0101] EER=

|Tindoor-Tincoil|×A+|Toutdoor-Toutcoil|×B+C

[0102] Among them, EER is the energy efficiency value of the air conditioner, Tindoor is the indoor ambient temperature, Tincoil is the indoor coil temperature, A is the indoor temperature correction factor, Toutdoor is the outdoor ambient temperature, Toutcoil is the outdoor coil temperature, B is the outdoor temperature correction factor, C is the frequency correction factor, and D is the operation mode correction factor.

[0103] In the embodiment, after determining the indoor temperature correction value, i.e., |Tindoor-Tincoil|×A, and the outdoor temperature correction value, i.e., |Toutdoor-Toutcoil|×B, the above parameters are combined with the frequency correction coefficient C and the operation mode correction coefficient D and brought into the air conditioner energy efficiency calculation formula. The air conditioner energy efficiency calculation formula is as follows:

[0104] EER=

|Tindoor-Tincoil|×A+|Toutdoor-Toutcoil|×B+C

[0105] By calculating the energy efficiency value EER of the air conditioner, the cooling capacity or heating capacity Q of the air conditioner 1 in the current operation mode of the air conditioner is calculated according to the energy efficiency value EER, so as to measure the capacity of the air conditioner in real time under different operation modes.

[0106] In some embodiments, the capability calculation formula includes:

[0107] Q=P×EER

[0108] Among them, Q is the cooling or heating capacity of the air conditioner, P is the power value of the air conditioner, and EER is the energy efficiency value of the air conditioner.

[0109] In the embodiment, after determining the energy efficiency value EER and the power value P of the air conditioner, the above parameters are substituted into the capacity calculation formula of the air conditioner, and the capacity calculation formula of the air conditioner is as follows:

[0110] Q=P×EER

[0111] The real-time capacity Q of the air conditioner is calculated according to the energy efficiency value EER and power value P of the air conditioner, thereby determining the heating capacity when the air conditioner is in the heating mode and the cooling capacity when the air conditioner is in the cooling mode.

[0112] In some embodiments, after determining the cooling capacity or heating capacity of the air conditioner in the current operating mode, it also includes: sending the cooling capacity or heating capacity of the air conditioner to the user terminal and / or the display screen of the air conditioner.

[0113] In an embodiment, after determining the cooling capacity or heating capacity of the air conditioner in the current operating mode, the controller sends the cooling capacity or heating capacity to a user terminal such as a mobile phone APP, and / or sends it to the display screen of the air conditioner for display, so that the user can understand the real-time status of the air conditioner.

[0114] According to the capacity calculation method of the air conditioner according to the embodiment of the present invention, after the air conditioner is turned on and operated, the operating parameters of the air conditioner in the operating state are obtained in real time, including power value, operating mode, indoor ambient temperature, indoor coil temperature, outdoor ambient temperature, outdoor coil temperature and frequency value of the compressor, and the capacity calculation formula of the air conditioner is used to calculate the real-time capacity of the air conditioner in the current operating mode, that is, the cooling capacity or heating capacity of the air conditioner is measured in real time. By using the capacity calculation formula of the air conditioner to calculate the real-time capacity, there is no need to calculate the capacity of the air conditioner according to the enthalpy difference method, so that the capacity calculation of the air conditioner is more convenient and accurate, and there is no need to realize the capacity detection of the air conditioner by adding additional devices, thereby reducing the hardware cost while reducing the hardware space occupied by the air conditioner.
