[0076] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0077] The embodiment of the present invention provides an air conditioner 10, which can be used to perform functions such as cooling, heating and dehumidification. In an optional implementation, the air conditioner is a split air conditioner, including an indoor unit and an outdoor unit, the indoor unit includes an air supply device such as an air outlet, and the outdoor unit refrigeration includes a refrigeration system composed of components such as a compressor, an evaporator, and a condenser. The specific structure and working principle of the indoor unit and the outdoor unit of the split air conditioner can refer to the prior art and will not be repeated here. In another implementation, the air conditioner is an integrated air conditioner, including an indoor unit, and the indoor unit integrates a functional system composed of air supply devices such as an air outlet and a compressor as a whole. The specific structure and working principle of the integrated air conditioner can refer to the prior art and will not be repeated here.

[0078] See also Figure 1, is a schematic diagram of the structure of the air conditioner provided in the embodiment of the present invention under the first preferred implementation mode. In the embodiment of the present invention, the air conditioner 10 further includes an indoor temperature sensor 11, a personnel parameter detection device 12 and a controller 13. The indoor temperature sensor 11 is used to collect the current indoor temperature Te, which can be set on the indoor unit housing of the air conditioner 10, or on a remote control of the air conditioner 10 placed indoors; the personnel parameter detection device 12 is used to collect the personnel parameters of the current room, which can be set on the indoor unit housing of the air conditioner 10, and the personnel parameters refer to parameter information related to the indoor personnel, such as the number of personnel, the type of personnel, etc. Optionally, the personnel parameter detection device 12 can collect the current personnel parameters in real time, or collect the personnel parameters once every first preset time length t1.

[0079] The controller 13 obtains the current indoor temperature Te collected by the indoor temperature sensor 11 and the current personnel parameters collected by the personnel parameter detection device 12, and generates an operation control instruction for the air conditioner to adjust the operation state of the air conditioner.

[0080] Specifically, see Figure 2 , is a flow chart of the work performed by the controller in the first preferred implementation mode in the embodiment of the present invention. The controller 13 is specifically used to perform steps S1 to S6:

[0081] S1, after the air conditioner is powered on, determining whether the temperature difference between the current indoor temperature and the preset target temperature is greater than a first preset temperature difference;

[0082] S2. When the temperature difference is greater than the first preset temperature difference, a first control operation is performed; the first control operation is: according to the correspondence between the preset personnel parameters and the operating capacity of the air conditioner, the operating capacity corresponding to the current personnel parameters is determined to control the operation of the air conditioner;

[0083] S3, determining whether the temperature difference is less than or equal to a second preset temperature difference; wherein the second preset temperature difference is less than or equal to the first preset temperature difference;

[0084] S4, if yes, control the air conditioner to stop; if no, continue to perform the first control operation;

[0085] S5, after the air conditioner is shut down, determining whether the temperature difference is less than or equal to a third preset temperature difference; wherein the third preset temperature difference is less than or equal to the first preset temperature difference;

[0086] S6. If yes, keep the air conditioner shut down; if not, execute the second control operation; the second control operation is: control the air conditioner to start running, and determine the operating capacity corresponding to the current personnel parameters and the current temperature difference according to the correspondence between the preset personnel parameters, the temperature difference and the operating capacity of the air conditioner, so as to control the operation of the air conditioner.

[0087] In an embodiment of the present invention, when the air conditioner is powered on, the user can input the required operating mode control instructions through a preset human-computer interaction module, such as a remote control, a touch screen on the air conditioner, or a voice module to control the air conditioner to enter a corresponding operating mode. In this operating mode, the air conditioner starts operating according to the original control strategy based on the target temperature Ts set by the user or the default setting.

[0088] Furthermore, the controller 13 obtains the current indoor temperature Te in real time, calculates the temperature difference △T=Te-Ts between the indoor temperature Te and the target temperature Ts, and compares it with the preset first preset temperature difference T1. If △T≤T1 is satisfied, the air conditioner continues to operate according to the original control strategy; if △T>T1 is satisfied, the first control operation is performed, that is, the current personnel parameters are obtained, and the operating capacity corresponding to the current personnel parameters is determined according to the corresponding relationship between the preset personnel parameters and the operating capacity of the air conditioner, and then the air conditioner is controlled to operate and output according to the determined operating capacity.

[0089] Preferably, the operating capacity of the air conditioner is positively correlated with the number of people. That is, if the number of people detected is more, the operating capacity of the air conditioner needs to be higher; if the number of people detected is less, the operating capacity of the air conditioner needs to be lower.

[0090] After executing the first control operation, the current temperature difference △T is compared with the preset second preset temperature difference T2 every second preset time t2; wherein T2≤T1. If △T≤T2 is satisfied, it indicates that after the adjustment of the first control operation, the current indoor environment temperature Te is close to the target temperature Ts, and the air conditioner is controlled to shut down in order to achieve energy saving effect without seriously affecting the comfort of the air-conditioned environment; if △T>T2 is satisfied, the first control operation is continued to be executed to determine the operating capacity corresponding to the current personnel parameters, and then the air conditioner is controlled to operate and output according to the determined operating capacity.

[0091] After the air conditioner is controlled to stop, the indoor temperature Te may gradually deviate from the target temperature Ts. Then, every third preset time t3, the current temperature difference △T is compared with the preset third preset temperature difference T3; wherein, T3≤T1, preferably, T1=T2. If △T≤T3 is satisfied, it indicates that the current indoor environment temperature Te is still close to the target temperature Ts, and no adjustment is required, and the air conditioner maintains the shutdown state; if △T>T3 is satisfied, it indicates that the indoor temperature Te has obviously deviated from the target temperature Ts, and the second control operation is performed at this time to make a more precise adjustment, that is, the air conditioner is controlled to start, and the current personnel parameters are obtained, and the specific range of the current temperature difference △T is determined. According to the correspondence between the preset personnel parameters, the temperature difference and the operating capacity of the air conditioner, the operating capacity corresponding to the current personnel parameters and the current temperature difference △T is determined, and then the air conditioner is controlled to operate and output according to the determined operating capacity.

[0092] Preferably, the operating capacity of the air conditioner is also positively correlated with the temperature difference, that is, if the current temperature difference is larger, the operating capacity required to be output by the air conditioner is higher; if the current temperature difference is smaller, the operating capacity required to be output by the air conditioner is lower.

[0093] It should be noted that T1, T2 and T3 are all pre-set values, which can be set and adjusted according to actual conditions. Preferably, T1 = 2°C, T2 = T3 = 1°C.

[0094] An embodiment of the present invention provides an air conditioner, which collects the current personnel parameters in the room by setting a personnel parameter detection device; after the air conditioner is powered on, the temperature difference between the current indoor temperature and the preset target temperature is calculated, and when the temperature difference is greater than the first preset temperature difference, the operating capacity corresponding to the current personnel parameters is determined according to the correspondence between the preset personnel parameters and the operating capacity of the air conditioner, and the operating capacity of the air conditioner is adjusted; after the adjustment, when the temperature difference is less than or equal to the second preset temperature difference, the air conditioner is controlled to be shut down, so as to achieve energy saving effect without seriously affecting the comfort of the air-conditioned environment; after the air conditioner is shut down, when the temperature difference is greater than the third preset temperature difference, the air conditioner is controlled to be turned on, and according to the correspondence between the preset personnel parameters, the temperature difference and the operating capacity of the air conditioner, the operating capacity corresponding to the current personnel parameters and the current temperature difference is determined, so as to more finely adjust the operating capacity of the air conditioner. By adopting the technical means of the embodiments of the present invention, it is possible to effectively identify indoor personnel parameter information, and in combination with the changes in the current ambient temperature, intelligently control the operating parameters of the air conditioner, and adjust the heat load fluctuations caused by the increase in the number of people, so as to improve the comfort of users in the air-conditioned environment; at the same time, it is possible to effectively reduce the power consumption of the air conditioner while ensuring that the comfort of the indoor environment is not affected, avoid the reduction of the service life of the air conditioner due to continuous operation or high-load operation, and effectively optimize the noise effect.

[0095] As a preferred embodiment, see Figure 3 , is a schematic diagram of the structure of the air conditioner in the second preferred embodiment of the present invention. The present invention is further implemented on the basis of the above embodiment, wherein the personnel parameter includes the number of personnel X, that is, the total number of personnel in the current room.

[0097] See Figure 4 , is a flow chart of the work performed by the controller in the embodiment of the present invention under the second preferred implementation mode, in step S2, the operation capacity corresponding to the current personnel parameter is determined according to the correspondence between the preset personnel parameter and the operation capacity of the air conditioner, and is used to control the operation of the air conditioner, including step S21:

According to the correspondence between the preset number of personnel, the temperature difference and the operating speed of the compressor, determine the operating speed of the compressor corresponding to the current number of personnel and the current temperature difference as the second target operating speed, and control the compressor to operate according to the second target operating speed.
