Problems solved by technology

In the current inverter air conditioner, the manufacturer solidifies the operating program of the inverter compressor in the chip, and the user can only choose different operating modes according to the needs, and cannot change the operating frequency of the compressor.
The resulting problem is that the user can only passively accept the operating mode of the air conditioner compressor set by the manufacturer, and cannot change the operating parameters of the compressor as needed to meet more different needs

example 1

[0101] Example 1 (for fixed frequency setting in cooling state)

[0102] like Figure 4a1 and Figure 4a2 As shown, in an environment where the indoor temperature t1=30 degrees and the outdoor temperature tw=36 degrees, at 22:00 in the evening, the user requires the indoor temperature to drop to 25 degrees within 15 minutes to quickly fall asleep, and then in the next 2 The hourly temperature is controlled at about 26 degrees, and then the temperature is controlled at about 27 degrees for the next 2 hours, and then shut down (because the body's resistance will be weakened during sleep, the temperature control is slightly different). If the user does not have high requirements for temperature control accuracy, the requirement can be met by setting the time period and frequency.

[0103] The user can set 26 degrees, open the set windshield, and then set the start time: 22:00, end time: 2:15; the first stage time: 15 minutes, the operating frequency: cooling high frequency; the...

[0104] Example 2 (for fixed frequency setting in heating state)

[0105] like Figure 4b1 and Figure 4b2 As shown, in an environment where the indoor temperature t1=6 degrees and the outdoor temperature tw=0 degrees, at 22:00 in the evening, the user requires the indoor temperature to rise to 15 degrees within 30 minutes to quickly fall asleep, and then in the next 2.5 The temperature is controlled at about 20 degrees for one hour, and then the temperature is controlled at about 21 degrees for the next 2.5 hours, and then the temperature is controlled at about 22 degrees for the next 2.5 hours, and then shut down (because the body's resistance will weaken in the sleep state, so The control temperature is slightly different). If the user does not have high requirements for temperature control accuracy, the requirement can be met by setting the time period and frequency.

[0106] The user can set 25 degrees, open the set windshield, and then set the start time: 22:00, end ti...

[0108] Example 3 (for variable frequency in operation under cooling state)

[0109] like Figure 4c1 and Figure 4c2 As shown, in an environment where the indoor temperature t1=30 degrees and the outdoor temperature tw=36 degrees, at 22:00 in the evening, the user requires the indoor temperature to drop to 25 degrees within 60 minutes to quickly fall asleep, and then in the next 2 The hourly temperature is controlled at about 26 degrees, and then the temperature is controlled at about 27 degrees for the next 2 hours, and then shut down (because the body's resistance will be weakened during sleep, the temperature control is slightly different). If the user does not have high requirements for temperature control accuracy, the requirement can be met by setting the time period and frequency. The user can set 26 degrees, open the set windshield, and then set the start time: 22:00, end time: 3:00; the first stage time: 60 minutes, operating frequency: cooling high frequency; when ...

Abstract

The invention discloses a variable-frequency air conditioner control method and an air conditioner. The variable-frequency air conditioner control method comprises the steps: entering a user setting mode in response to a user operation instruction; acquiring a running frequency, which is set by a user, of an air conditioner compressor; controlling the air conditioner compressor to run at the set running frequency. Furthermore, the user can also set different running time periods of a variable-frequency air conditioner compressor and the running time lengths and the running frequencies of all the time periods; in each running time period set by the user, the air conditioner compressor is controlled to run at the set running time length and the running frequency; moreover, a difference value between the set temperature ts and the indoor temperature t1 can be judged in any time period after the air conditioner compressor runs according to the preset time length or a default time length, and frequency rising and frequency falling are determined according to the difference value or the current frequency is kept until the period is ended; the comfortableness of the air conditioner is guaranteed, and energy conservation of the air conditioner can be realized; more different demands of the user are met.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an inverter air conditioner control method and an air conditioner in which the user can set the operating frequency, operating stages and operating time of each stage. Background technique [0002] With the development of the economy, people's quality of life is constantly improving, and there are higher requirements for the comfort performance of air conditioners. However, under the premise of ensuring comfort, it is necessary to save energy as much as possible. High-quality air-conditioning is the unremitting pursuit of major air-conditioning manufacturers. [0003] Generally, the operation of a fixed-speed air conditioner is performed by the user to select basic parameters such as operation mode, wind speed and set temperature. However, the emergence of inverter air conditioners has given users more choices and made it possible to achieve a more comfortable sp...
