s01, determining the actual length of the air conditioner on-line pipe;
and S02, determining the target exhaust temperature of the air conditioner according to the actual length of the air conditioner on-line pipe.

Optionally, determining the target exhaust temperature of the air conditioner according to the actual length of the air conditioner online pipe comprises: and determining the target exhaust temperature of the air conditioner according to the difference value between the actual length of the air conditioner on-line pipe and a default length. Like this, the air conditioner can set up the default length of an online pipe when the installation, and the actual length of the different online pipes of actual installation condition can change according to the air conditioner in the installation, and the air conditioner calculates the target exhaust temperature of air conditioner through the default length of online pipe when leaving the factory to set up, and when actual length is different with default length, utilizes the difference of actual length and default length to confirm the target exhaust temperature of air conditioner, and is more accurate, can improve the operating efficiency of air conditioner.
Optionally, the difference between the actual length of the air conditioner on-line pipe and a default length includes: acquiring the actual length of an air conditioner on-line pipe; and comparing the actual length with the default length, and calculating a difference value. Therefore, the actual length of the air conditioner online pipe is different according to different installation conditions, the actual length of the air conditioner online pipe is firstly obtained, the difference value is calculated through comparison, the target exhaust temperature of the air conditioner is determined through the difference value, and the target exhaust temperature of the air conditioner can be determined more accurately.
Optionally, the obtaining the actual length of the air conditioner online pipe comprises: and inputting the actual length of the air-conditioning on-line pipe when the air-conditioning on-line pipe is installed. Therefore, when the air conditioner on-line pipe is installed, the installer inputs the actual length of the air conditioner on-line pipe, and the actual length of the air conditioner on-line pipe can be more accurately determined.
Optionally, inputting the actual length of the air conditioning on-line pipe comprises: a plurality of address bits are arranged in a storage of the air conditioner and respectively correspond to a plurality of actual lengths of the on-line pipes, and the address bits in the storage are selected to indicate the actual lengths of the on-line pipes during installation. Therefore, the actual length of the air-conditioning on-line pipe can be input more conveniently during installation by selecting the address bit in the storage to indicate the actual length of the on-line pipe. For example, 8 address bits are set in storage: d1, d2, d3, d4, d5, d6, d7 and d8 respectively correspond to a refrigerating 0.5-meter on-line pipe, a 0.75-meter on-line pipe, a 1-meter on-line pipe, a 1.25-meter on-line pipe, a 1.5-meter on-line pipe, a 1.75-meter on-line pipe, a 2-meter on-line pipe and a 2.15-meter on-line pipe, and the address position of the d7 in the storage is directly selected by selecting the 2-meter on-line pipe during installation.
Optionally, determining the target exhaust temperature of the air conditioner according to the difference comprises: determining a parameter d corresponding to the difference value; calculating a x f + b + c + d, and determining the target exhaust temperature of the air conditioner; wherein a and b are constants set by the system, f is the running frequency of the compressor, and c is an outdoor environment temperature compensation constant. In this way, the parameter related to the difference between the actual length and the default length is added into the calculation formula for determining the target exhaust temperature, and the difference is used as a parameter for determining the target exhaust temperature of the air conditioner, so that the method is more accurate and can improve the operating efficiency of the air conditioner.
Optionally, a and b are fixed values set according to the air conditioner model; wherein a is more than or equal to 0.6 and less than or equal to 0.7, and b is more than or equal to 15 and less than or equal to 40. Therefore, parameters of the target exhaust temperature are calculated according to air conditioners of different models, the target exhaust temperature is calculated more accurately, and the operating efficiency of the air conditioner is improved.
Optionally, c is determined according to the interval of the ambient temperature. For example, at ambient temperature of [ -5, 0] degrees, -10 ≦ c ≦ -3; when the environmental temperature is 0, 5 degrees, c is more than or equal to-5 and less than or equal to 3. Therefore, the numerical value of the parameter c is adjusted in different environmental temperatures, the influence of the outdoor environmental temperature on the operation of the air conditioner is reduced, and the operation efficiency of the air conditioner is improved.

Optionally, when the outdoor environment temperature is within a preset range, determining the parameter d according to the difference and the compressor operating frequency; or, when the outdoor environment temperature is out of the preset range, determining the parameter d according to the outdoor environment temperature. Therefore, the outdoor environment temperature has great influence on the operation of the air conditioner, the difference value between the actual length and the default length of the on-line pipe has obvious influence on the operation of the air conditioner when the air conditioner normally operates within a certain range, the parameter corresponding to the difference value is considered in the parameter for controlling the air conditioner, the air conditioner can operate more efficiently, but when the outdoor environment temperature is in a special condition, the length of the on-line pipe has small influence on the operation of the whole air conditioner, the outdoor environment temperature is used as an important parameter for controlling the operation of the air conditioner, and the air conditioner can operate more efficiently.
Optionally, determining the parameter d according to the difference and the compressor operating frequency comprises: when the running frequency of the compressor is less than or equal to a preset threshold value, d is equal to l1(ii) a When the running frequency of the compressor is greater than or equal to a preset threshold value, d is equal to l12; wherein l1Is the increased length of the actual length of the air conditioning on-line pipe compared to the default length. Therefore, when the compressor runs at different frequencies, the influence degree of the length of the on-line pipe on the running of the compressor is different, so that the difference of the length of the on-line pipe on the adjustment degree of the running of the air conditioner under different running frequencies of the compressor is distinguished, and the running efficiency of the air conditioner can be higher.
Alternatively,/1In meters.
Optionally, when the air conditioner is in a cooling mode, the preset threshold value is f1Air conditioner heating modeWhen the preset threshold is f2. Therefore, the preset threshold values of the cooling mode and the heating mode are different, so that the accuracy of calculating the target exhaust temperature is improved according to different determining conditions of different parameters d of the operation mode of the air conditioner, and the operation efficiency of the air conditioner is improved.

Alternatively, f1Is 60 Hz. Thus, when the running frequency of the compressor in the refrigeration mode is less than or equal to 60 Hz, the parameter d is equal to-l1The difference between the actual length of the air conditioner on-line pipe and the default length has less influence on the operation efficiency of the air conditioner, and the parameter d is set to be d-l1The operation of the air conditioner can be corrected, the operation efficiency of the air conditioner can be improved under the condition of smaller correction degree, and when the operation frequency of the compressor is more than 60 Hz, d is equal to-l12, the difference of the actual length of the air conditioner on-line pipe compared with the default length has a large influence on the operation efficiency of the air conditioner, and the parameter d is set to be d-l1And 2, the operation of the air conditioner can be corrected, the required correction degree is larger, and the operation efficiency of the air conditioner can be improved.
Alternatively, f2Is 75 Hz. Thus, when the running frequency of the compressor in the heating mode is less than or equal to 75 Hz, the parameter d is equal to l1The difference between the actual length of the air conditioner on-line pipe and the default length has less influence on the operation efficiency of the air conditioner, and the parameter d is set to be d-l1The operation of the air conditioner can be corrected, the operation efficiency of the air conditioner can be improved under the condition of smaller correction degree, and when the operation frequency of the compressor is more than 75 Hz, d is-l12, the difference of the actual length of the air conditioner on-line pipe compared with the default length has a large influence on the operation efficiency of the air conditioner, and the parameter d is set to be d-l1Air conditioner operationThe correction is carried out, the required correction degree is larger, and the operation efficiency of the air conditioner can be improved.
Optionally, determining the parameter d according to the outdoor environment temperature includes: when the air conditioner is in a refrigeration mode and the outdoor environment temperature is greater than the highest temperature of the preset range, d is l2(ii) a When the air conditioner is in a heating mode and the outdoor environment temperature is lower than the lowest temperature of the preset range, d is l3(ii) a Wherein l2And l3Is a fixed value. When the outdoor environment temperature exceeds the value of the outdoor environment temperature when the air conditioner normally works, the parameter d is set to be a fixed value, the operation process of the air conditioner is regulated and controlled, the influence of the outdoor environment temperature on the operation of the air conditioner is reduced, and the operation efficiency of the air conditioner when the outdoor environment temperature exceeds the value of the outdoor environment temperature when the air conditioner normally works is improved.
Alternatively,/2＞l3. Thus, the outdoor ambient temperature has less effect on the air conditioner in the cooling mode than in the heating mode, and therefore2＞l3In the process, the correction on the operation of the air conditioner in the cooling mode is smaller than that in the heating mode, and the operation efficiency of the air conditioner can be improved to the maximum extent in different working modes of the air conditioner.
Alternatively,/2Is-2. Therefore, under the condition that the outdoor environment temperature exceeds the preset range, the influence of the change of the length of the air conditioner online pipe on the operation efficiency of the air conditioner is small, the aim of accurately calculating the target exhaust temperature can be fulfilled by directly setting the parameter d to be-2 when the air conditioner is in a refrigeration mode, the operation efficiency of the air conditioner is improved, and the unnecessary calculation amount is reduced.
Alternatively,/3Is-4. Therefore, under the condition that the outdoor environment temperature exceeds the preset range, the influence of the change of the length of the air conditioner online pipe on the operation efficiency of the air conditioner is small, the aim of accurately calculating the target exhaust temperature can be fulfilled by directly setting the parameter d to be 4 when the air conditioner is in a heating mode, the operation efficiency of the air conditioner is improved, and the unnecessary calculation amount is reduced.
Optionally, the preset range includes: when the air conditioner is in a refrigeration mode, the preset range is [ infinity, 40] DEG; when the air conditioner is in the heating mode, the preset range is [ -5, + ∞ ] degrees. Therefore, when the air conditioner is in a cooling mode, the air conditioner can normally operate when the outdoor environment temperature is less than 40 ℃, when the air conditioner is in a heating mode, the air conditioner can normally operate when the outdoor environment temperature is greater than-5 ℃, most of the outdoor environment temperature in one year in most of domestic areas is within the preset range, and the air conditioner normally operates in most of the time. For example, when the air conditioner is in a cooling mode and the outdoor ambient temperature is 45 degrees, d is set to-2; when the empty jacket is in a heating mode and the outdoor environment temperature is-8 ℃, d is set to-4.
