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] Such as figure 1 As shown, in order to solve the problem that the air conditioner cannot accurately control its own parameters according to the actual indoor temperature and humidity conditions under the existing cooling conditions, and then cause the difference between the indoor humidity and the user's habitual humidity when the indoor temperature reaches the user's habitual temperature The larger problem, the air conditioner of the present invention includes a compressor, a throttling device, an indoor fan and an indoor coil, and the control method includes:

[0051] S100. Acquiring indoor actual temperature T and actual humidity RH.

[0052] For example, the actual temperature and humidity in ...

Embodiment 2

[0084] 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.

[0085] 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.

[0086] Such as image 3 As shown, in a preferred embodiment, the control method of the air conditioner also includes:

[0087] S110. Obtain the preset start-up time and outdoor ambient temperature of the air conditioner.

[0088] 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

[0106] 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 parameters of the air conditioner such as the frequency of the compressor and the speed of the blower are properly adjusted, 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.

[0107] 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.

[0108] Such...

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. In order to solve the problem that whenthe indoor temperature of an existing air conditioner under the refrigeration working condition reaches the habitual temperature of a user, the difference between the indoor humidity and the habitualhumidity of the user is large, the control method comprises the steps of obtaining a preset startup moment of the air conditioner, correcting the preset startup moment, determining an early startingmoment based on preset air conditioning time and the corrected preset startup moment, acquiring indoor actual temperature T and indoor actual humidity RH, calculating an indoor dew point temperature Tes, comparing the T with Ts and the RH with RHs based on the habitual information of the user, and controlling the frequency of a compressor, the starting degree of a throttling device and the air speed of an indoor fan based on a comparison result and the dew point temperature Tes so as to enable Tp to be matched with the Tes. According to the control method of the air conditioner under the refrigeration working condition, the refrigeration degree and the dehumidification degree can be controlled, so that when the T reaches the Ts, the RH also reaches the standard of the RHs, and the early 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] As the main equipment for adjusting indoor temperature and humidity, air conditioners have been used by more and more users. During the cooling process of the air conditioner in summer, the coil temperature is low, and the indoor air passes through the coil to reduce the indoor temperature. [0003] While the air conditioner is cooling down, due to the low temperature of the coil, it will also reduce the indoor humidity accordingly due to the phenomenon of condensation. In the northern regions where the summer climate is relatively dry, the humidity is not high enough, and users do not want to dehumidify. However, during the cooling process, due to the unreasonable control of the coil temperature, the indoor humidity is lower, which cannot make the user dehumidif...
