Embodiment 1

[0049] First refer to figure 1 , to describe the control method of the air conditioner under the refrigeration 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 advance 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, control methods include:

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

[0052] For example, the actual indoor temperature and humidity can be detected through a detection module provided in the air conditioner, for example, a temperature sensor and a hum...

Embodiment 2

[0087] In order to solve the problem that the existing preset startup time and air conditioning time are not accurate enough, the present invention adds compensation for the preset startup 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 cooling condition according to the second embodiment of the present invention.

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

[0090] S110. Acquire the preset startup time of the air conditioner and the outdoor ambient temperature.

[0091] The preset power-on time in this embodiment may be a power-on time set actively by a user, or may be a power-on time based on statistics of historical power-on times of the air conditioner. For example, the preset start-up time may be the start-up time set by the user through the remote control, mob...

Embodiment 3

[0110] The third embodiment of the present invention, on the basis of the second embodiment, removes the step of determining the air conditioning time based on the outdoor ambient temperature, but directly specifies a fixed air conditioning time. Because, as long as the compressor frequency is properly selected, it can be ensured that the adjustment can be completed within a fixed air conditioning time every time. However, correspondingly, there will be a certain error relative to the air conditioning time of the second embodiment, so there will also be a certain error in the final determined advance opening time, but the error here is within an acceptable range.

[0111] For specific examples, see Figure 4 ,in, Figure 4 This is a flow chart of the control method of the air conditioner under the cooling condition according to the third embodiment of the present invention.

[0112] like Figure 4 As shown, in a possible implementation, the control method of the air conditi...

Abstract

The invention belongs to the field of air conditioners, and specifically provides a control method of the air conditioner under refrigeration conditions. The invention aims to solve the problem that the air conditioner cannot accurately balance the indoor humidity and the indoor temperature during the advance cooling process, and the control method includes: obtaining the preset startup time and the outdoor ambient temperature; determining the air conditioning time; determining the advance opening time; When reaching the early opening time, obtain the actual temperature T and actual humidity RH in the room; compare T with the customary temperature T s size, and RH versus customary humidity RH s The size of the compressor; selectively determine the operating frequency of the compressor, and control the compressor to start running at the operating frequency. Through the above method, it is determined whether the main task of the air conditioner is dehumidification or refrigeration, and the frequency of the compressor is determined, so that the air conditioner can take into account the indoor temperature and humidity, and balance the indoor temperature and humidity before the user turns on the air conditioner. time is more accurate.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a control method of the air conditioner under refrigeration conditions. Background technique [0002] Air conditioners are widely used in daily life. In hot summer, in actual use, users turn on the air conditioner after arriving home, and they need to go through a long waiting period for temperature adjustment before they can 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's waiting time. [0003] However, since both pre-cooling and pre-dehumidification are based on the principle of refrigeration, the process of pre-cooling may be accompanied by changes in indoor humidity, and correspondingly, the process of pre-dehumidification will als...
