Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The comfort survey finds that if a user is in a constant-temperature refrigeration mode for a long time, the user feels cooler and stuffier, and if the user is in a constant-temperature heating mode for a long time, the user feels drier and hotter, so that the user comfort is poor.
Example one
Referring to fig. 1 and 2, in the present embodiment, when the room temperature is at a constant temperature, fig. 1 shows a flowchart of an embodiment of a control method of an inverter air conditioner of the present invention, and fig. 2 shows a flowchart of another embodiment of the control method of the inverter air conditioner of the present invention.
Specifically, referring to fig. 1, the air conditioner is powered on to operate and a cooling mode is turned on, at which time the compressor starts cooling operation, detects an indoor ambient temperature Tc after a minutes (e.g., 90 minutes) of operation of the compressor, stores Tc and an indoor set temperature Ts at Tc ≦ Tset1 (e.g., 24 ℃), and when Te = | Ts-Tc | ≦ T1 (e.g., 1 ℃) continuously n times (e.g., 5 times) for a certain period of time, may generate a feeling of getting colder due to a user being in a constant temperature room at this time, and therefore, in this case, the indoor set temperature is increased from Ts to Ts 'and the air conditioner is continuously operated for b minutes (e.g., 30 minutes) with the indoor set temperature being Ts', at which time the compressor is operated at a lower frequency due to an increase in the cooling mode, energy saving is achieved, and after the operation for b minutes, the air conditioner automatically restores the indoor set temperature from Ts' to Ts and continuously operates for c minutes (for example, 30 minutes) under the condition of the indoor set temperature Ts, and then the air conditioner detects the indoor environment temperature Tc again, and during the operation of the air conditioner, if Tc still meets Tc ≦ Tset1, the air conditioner still circularly realizes refrigeration in the mode described above. Due to the refrigeration mode, a constant temperature field in a room is broken through temperature circulating type low-high-low change, a temperature environment with temperature fluctuation is formed in a temperature room in the refrigeration mode, and the comfort of a user is improved.
Referring again to fig. 1, the air conditioner is powered on and operated and a heating mode is turned on, at which time the compressor starts a heating operation, after a minutes (e.g., 90 minutes) of the operation of the compressor, an indoor ambient temperature Tc is detected, when Tc ≧ Tset2 (e.g., 24 ℃), when Tc and an indoor set temperature Ts are stored, and when Te = | Ts-Tc | ≦ T2 (e.g., 1 ℃) continuously n ' times (e.g., 5 times) within a certain period of time, a feeling of getting drier and hotter may be generated due to a user being in a constant temperature room, so in this case, the indoor set temperature is decreased from Ts to Ts ″ and the air conditioner is continuously operated for b ' minutes (e.g., 30 minutes) with the indoor set temperature being Ts ″, at which time the compressor is operated at a lower frequency due to the decrease in the heating mode, energy saving is achieved, and after b ' minutes of operation, the air conditioner automatically restores the indoor set temperature from Ts 'to Ts and continuously operates the air conditioner for c' minutes (for example, 30 minutes) under the condition of the indoor set temperature Ts, and then the air conditioner detects the indoor ambient temperature Tc again, and during the operation of the air conditioner, if Tc still meets Tc ≧ Tset2, the air conditioner still circularly realizes heating in the manner described above. Due to the heating mode, a constant temperature field in a room is broken through the temperature cycling type high-low-high change, a temperature environment with temperature fluctuation is formed in the temperature room under the heating mode, and the comfort of a user is improved.
Example two
In order to further improve the comfort degree in the constant temperature field in the heating mode or the cooling mode, the temperature stratification in the room is disturbed by using the change of the air volume under the condition of breaking the constant temperature field in the room, and the comfort degree of a user is improved. Preferably, referring to fig. 2, fig. 2 shows a flow chart of another embodiment of the control method of the inverter air conditioner of the present invention, which is different from fig. 1 in that the temperature stratification in the room is disturbed by changing the air volume in case of breaking the constant cooling temperature field in the room.
Specifically, referring to fig. 2, the air conditioner is powered on and operated and a cooling mode is turned on, at which time the compressor starts cooling operation, detects an indoor ambient temperature Tc after a minutes (e.g., 90 minutes) of operation of the compressor, stores Tc, an indoor fan rotational speed R, and an indoor set temperature Ts at Tc ≦ Tset1 (e.g., 24 ℃), may generate a cooling sensation due to a user being in a constant temperature room when Te = | Ts-Tc | ≦ T1 (e.g., 1 ℃) continuously n times (e.g., 5 times) within a certain period of time, and thus, in this case, the indoor set temperature is increased from Ts to Ts ' and the indoor fan rotational speed R ' = R + R0.1 is increased, and the air conditioner is continuously operated for b minutes (e.g., 30 minutes) at the indoor set temperature Ts ', and at which the compressor is operated at a lower frequency due to the increase in the set temperature at the cooling mode, energy saving is achieved, after the air conditioner is operated for b minutes, the air conditioner automatically restores the indoor set temperature from Ts 'to Ts and the indoor set temperature from R' to R, the air conditioner is continuously operated for c minutes (for example, 30 minutes) under the condition of the indoor set temperature Ts, then the air conditioner detects the indoor environment temperature Tc, and during the operation of the air conditioner, if Tc still meets Tc not more than Tset1, the air conditioner still realizes refrigeration in a circulating mode in the mode described above. Due to the refrigeration mode, a constant temperature field in a room is broken through temperature circulating type low-high-low change, air volume is increased when temperature rises, the temperature field in the room is disturbed, a user is prevented from being increasingly cold under a constant temperature refrigeration mode all the time, a temperature environment with temperature fluctuation is formed in the temperature room under the refrigeration mode, and user comfort is improved.
Referring again to fig. 2, the air conditioner is powered on and turned on in a heating mode, at which time the compressor starts heating operation, detects an indoor ambient temperature Tc after the compressor is operated for a minutes (e.g., 90 minutes), stores Tc, an indoor fan speed R and an indoor set temperature Ts when Tc ≧ Tset2 (e.g., 24 ℃), and may generate a sensation of getting drier and hotter due to a user being in a constant temperature room when Te = | Ts-Tc | ≦ T2 (e.g., 1 ℃) continuously exists n ' times (e.g., 5 times) within a certain period of time, so in this case, the indoor set temperature is decreased from Ts to Ts ″ and the indoor fan speed R ' = R-R × 0.1 is decreased, and the air conditioner is continuously operated for b ' minutes (e.g., 30 minutes) with the indoor set temperature being Ts ″, at which the compressor is operated at a lower frequency due to the decrease in the set temperature in the heating mode, energy saving is achieved, after b ' minutes of operation, the air conditioner automatically restores the indoor set temperature from Ts ' ' to Ts and R ' to R, the air conditioner is continuously operated for c ' minutes (for example, 30 minutes) under the condition of the indoor set temperature Ts, then the air conditioner detects the indoor environment temperature Tc again, and during the operation of the air conditioner, if Tc still meets Tc ≧ Tset2, the air conditioner circularly achieves heating in the mode described above. Due to the heating mode, a constant temperature field in a room is broken through temperature circulation type high-low-high change, air volume is reduced when temperature is reduced, the temperature field in the room is disturbed, the situation that a user gets dry and hot all the time in a constant heating mode is avoided, a temperature environment with temperature fluctuation is formed in the temperature room in the heating mode, and user comfort is improved.
In this embodiment, the manner of adjusting the indoor fan rotation speed in the heating or cooling mode is not limited to the above, and for example, the indoor fan rotation speed may be decreased when the indoor set temperature is increased from Ts to Ts 'in the cooling mode, or the indoor fan rotation speed may be increased when the indoor set temperature is decreased from Ts to Ts' in the heating mode, or the indoor fan rotation speed may not be decreased according to the above equation R '= R-R0.1, or the indoor fan rotation speed may not be increased according to the above equation R' = R + R0.1, without limitation.
