Embodiment 1

[0023] This embodiment is aimed at the case where the room temperature is at a constant temperature, please refer to figure 1 and figure 2 , figure 1 A flow chart showing an embodiment of the control method of the inverter air conditioner of the present invention, figure 2 A flow chart of another embodiment of the control method of the inverter air conditioner of the present invention is shown.

[0024] Specifically, refer to figure 1 , the air conditioner is powered on and turns on the cooling mode. At this time, the compressor starts cooling operation. After the compressor runs for a minute (for example, 90 minutes), the indoor ambient temperature Tc is detected. When Tc≤Tset1 (for example, 24°C), this Store Tc and indoor set temperature Ts at any time, and when Te=|Ts-Tc|≤T1 (for example 1°C) exists n consecutive times (for example, 5 times) within a certain period of time, it may be because the user is in a room with a constant temperature. produce a feeling of getti...

Embodiment 2

[0027] In order to further improve the comfort in the constant temperature field in heating mode or cooling mode, the change of air volume is used to disturb the temperature stratification in the room while breaking the constant temperature field in the room, so as to improve user comfort. Preferably, please refer to figure 2 , figure 2 Shows the flow chart of another embodiment of the control method of the inverter air conditioner of the present invention, which is the same as figure 1 The difference is that the temperature stratification in the room is disturbed by changing the air volume while breaking the constant cooling temperature field in the room.

[0028] Specifically, refer to figure 2 , the air conditioner is powered on and turns on the cooling mode. At this time, the compressor starts cooling operation. After the compressor runs for a minute (for example, 90 minutes), the indoor ambient temperature Tc is detected. When Tc≤Tset1 (for example, 24°C), this Stor...

Embodiment 3

[0032] figure 1 and figure 2 The realization of the control method in is based on the control system of this embodiment, wherein the control system includes a main controller, and the main controller is used to execute figure 1 and figure 2 The control method described in , and the main controller includes a timing unit and a temperature detection unit, wherein both the timing unit and the temperature detection unit can be integrated in the main controller, and the timing unit is used to time the time involved in the process of the control method , for example, a, b, b', c, c', etc.; the main controller is also integrated with a memory, which is used to detect the indoor ambient temperature Tc after the compressor runs for cooling for a minute. When Tc≤Tset1, store Tc, indoor fan speed R and indoor set temperature Ts, or used to detect the indoor ambient temperature Tc after a minute of compressor heating operation, when Tc≥Tset2, store Tc, indoor fan speed R and indoor se...

Abstract

The invention relates to a control method and a control system of a variable-frequency air conditioner, the variable-frequency air conditioner. The method comprises the following steps that S1, the air conditioner is powered-on to stably run a minutes; S2, the indoor environment temperature Tc is detected; S3, when the air conditioner is in a constant-temperature refrigeration mode and the Tc is less than or equal to Tset 1, or the air conditioner is in a constant-temperature heating mode and the Tc is larger than or equal to Tset 2, the absolute value Te of the temperature difference betweenTs and Tc is calculated; S4, under the constant-temperature refrigeration mode, if the Te is less than or equal to T1 for continuous n times in a preset time period, then the Ts is increased to Ts', and the air conditioner is enabled to continuously run for b minutes, or under the constant-temperature heating mode, if the Te is less than or equal to T2 for continuous n' times in a preset time period, then the Ts is reduced to Ts", and the air conditioner is enabled to continuously run for b' minutes; and S5, after the air conditioner runs continuously for the b minutes, the Ts' or the Ts" is restored to the TS, and after the air conditioner runs c minutes, the S2 to the S5 are repeated. According to control method the of the variable-frequency air conditioner, the comfort level of a user is improved, and energy conservation is realized.

Description

technical field [0001] The invention belongs to the technical field of air conditioner control, and in particular relates to a control method, a control system and the frequency conversion air conditioner. Background technique [0002] Existing indoor air conditioners are divided into ordinary fixed-speed air conditioners and inverter air conditioners. Ordinary fixed-speed air conditioners adjust the temperature in the room by controlling the on and off of the compressor. As a result, the temperature is relatively constant, and the room temperature fluctuates greatly due to the constant startup and shutdown of the compressor. According to the set temperature, the inverter air conditioner adjusts the operating speed of the compressor to adjust the room temperature to keep the room temperature at the set temperature. It is concluded that the user will feel uncomfortable in a room with a constant temperature for a long time. If the user is in a room with a constant temperature...
