Embodiment 1

[0049] 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.

[0050] like 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:

[0051] S100. When the air conditioner is in a shutdown state, acquire the actual temperature T and the actual humidity RH in the room.

[0052] 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 a h...

Embodiment 2

[0087] 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.

[0088] 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.

[0089] Such as image 3 As shown, in a preferred embodiment, the control method of the air conditioner also includes:

[0090] S110. Obtain the preset start-up time and outdoor ambient temperature of the air conditioner.

[0091] 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

[0110] 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.

[0111] 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.

[0112] 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 in particular relates to a control method of an air conditioner in a refrigerating working condition. The control method aims to solve the problem that it cannot balance indoor humidity and indoor temperature precisely in an advanced refrigerating process of the air conditioner. The control method comprises the following steps of acquiring a preset starting moment and an outdoor environment temperature; determining an air regulating time; determining an advanced starting moment; acquiring the actual temperature T and the actual humidity RH in a room when reaching the advanced starting time; comparing the amplitudes of T and a habit temperature Ts and RH and habit humidity RHs; and selectively determining the operating frequency ofa compressor and controlling the compressor to start to operate at an operation frequency. In this way, whether the main task of the air conditioner is dehumidification or refrigeration is determined, and the frequency of the compressor is determined, so that the air conditioner can consider temperature and humidity indoors. Before a user starts the air conditioner, the indoor temperature and humidity are balanced, so that the advanced starting moment 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...
