Embodiment 1

[0052] First refer to figure 1 , to describe the control method of the air conditioner under the cooling condition of the present invention. in, figure 1 It is a flow chart of the control method of the air conditioner under the cooling condition of the present invention.

[0053] Such as figure 1 As shown, in order to solve the problem that the existing air conditioner cannot accurately balance the indoor humidity and the indoor temperature during the pre-cooling process, the air conditioner of the present invention includes a compressor, an indoor heat exchanger, an indoor fan, and an outdoor heat exchanger and outdoor fans, the control methods include:

[0054] S100. When the air conditioner is in a shutdown state, acquire the actual temperature T and the actual humidity RH in the room.

[0055] For example, the actual temperature and humidity in the room can be detected through the detection module provided in the air conditioner, such as using a temperature sensor and ...

Embodiment 2

[0090] In order to solve the problem that the existing preset power-on time and air-conditioning time are not accurate enough, the present invention adds compensation for the preset power-on time and air-conditioning time before step S100 in the first embodiment.

[0091] see image 3 ,in, image 3 It is a flow chart of the control method of the air conditioner under the refrigeration working condition according to the second embodiment of the present invention.

[0092] Such as image 3 As shown, in a preferred embodiment, the control method of the air conditioner also includes:

[0093] S110. Obtain the preset start-up time and outdoor ambient temperature of the air conditioner.

[0094] The preset power-on time in this embodiment may be a power-on time actively set by the user, or a power-on time calculated based on historical power-on time of the air conditioner. For example, the preset start-up time can be the start-up time set by the user through the remote control, ...

Embodiment 3

[0113] In the third embodiment of the present invention, on the basis of the second embodiment, the step of determining the air-conditioning time based on the outdoor ambient temperature is removed, and a fixed air-conditioning time is directly specified. Because, as long as the compressor frequency is properly selected, it can be guaranteed that the adjustment can be completed within the fixed air conditioning time every time. But correspondingly, there will be a certain error compared to the air conditioning time of the second embodiment, so the final determined early opening time will also have a certain error, but the error here is within an acceptable range.

[0114] Specific examples see Figure 4 ,in, Figure 4 It is a flow chart of the control method of the air conditioner under the refrigeration working condition according to the third embodiment of the present invention.

[0115] Such as Figure 4 As shown, in a possible implementation manner, the control method o...

Abstract

The invention belongs to the field of air-conditioners, and particularly provides a control method of an air-conditioner under a refrigeration working condition. The method aims to solve the problemsthat in the advance refrigerating process of an air-conditioner, indoor humidity and indoor temperature cannot be balanced accurately. The control method comprises the steps that preset starting timeis obtained; the preset starting time is corrected; advance starting time is determined; when the advance starting time is up, actual temperature T and actual humidity RH in a room are obtained; T andhabit temperature Ts are compared, and RH and habit humidity RHs are compared; and operation frequency of a compressor is determined selectively, and a compressor is controlled to be started to operate at the operation frequency. By means of the manner, whether a main task of the air-conditioner is dehumidifying or refrigerating is determined, the frequency of the compressor is determined, the air-conditioner can consider both indoor temperature and humidity, the indoor temperature and humidity are balanced before a user starts the air-conditioner, and thus time for advance starting is more accurate.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a method for controlling an air conditioner under cooling conditions. Background technique [0002] Air conditioners are widely used in daily life. In the hot summer, when the user turns on the air conditioner after arriving home, it still needs a long waiting period for temperature adjustment in order to achieve the comfortable environment specified by the user. In the prior art, the control method for the air conditioner may be to change the indoor temperature in advance by cooling in advance, or change the indoor humidity by dehumidifying in advance, so as to save the user from waiting time. [0003] However, since advance cooling and advance dehumidification are both based on the principle of refrigeration, the process of advance cooling may be accompanied by changes in indoor humidity, and correspondingly, the process of advance dehumidification may also b...
