Problems solved by technology

[0005] In order to solve the above problems in the prior art, that is, in order to solve the problem that the air conditioner cannot accurately control its own parameters according to the actual temperature and humidity in the room under the existing refrigeration working conditions, and then cause when the indoor temperature reaches the user's habitual temperature, In order to solve the problem that the indoor humidity is quite different from the user’s customary humidity, the present invention provides a control method for an air conditioner under cooling conditions. The air conditioner includes a compressor, a throttling device, an indoor fan and an indoor coil. In that, the control method includes:

Embodiment 1

[0050] 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.

[0051] like 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 under the existing refrigeration conditions, it will cause the indoor humidity to be different from the user's habitual humidity when the indoor temperature reaches the user's habitual temperature. The bigger problem is that 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:

[0052] S100. Acquire the actual indoor temperature T and the actual humidity RH.

[0053] For example, the actual indoor temperature and ...

Embodiment 2

[0085] 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.

[0086] 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.

[0087] like image 3 As shown, in a preferred embodiment, the control method of the air conditioner further includes:

[0088] S110. Acquire the preset startup time of the air conditioner and the outdoor ambient temperature.

[0089] 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

[0107] 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 parameters of the air conditioner such as compressor frequency and blower speed are properly adjusted, 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.

[0108] 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.

[0109] like Figure 4 As shown, in a po...

Abstract

The invention belongs to the field of air conditioners, and specifically provides a control method of the air conditioner under refrigeration conditions. Under the existing refrigeration conditions, when the indoor temperature of the air conditioner reaches the user's habitual temperature, the indoor humidity is quite different from the user's habitual humidity. The control method of the present invention includes: acquiring the preset startup time of the air conditioner and the outdoor ambient temperature, Correct the preset startup time, determine the air conditioning time, determine the advance startup time, obtain the actual indoor temperature T and actual humidity RH, and calculate the indoor dew point temperature T es , based on user habit information, compare T and T s size, and RH vs. RH s size, based on comparison results and dew point temperature T es , control the frequency of the compressor, the opening of the throttling device, and the wind speed of the indoor fan, so that T p with T es fit. The present invention can control the degree of refrigeration and the degree of dehumidification, so as to make T reach T s , RH has also reached RH s The standard also makes the early opening time more accurate.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a control method of an air conditioner under refrigeration 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 temperature of the coil is low, and the indoor air passes through the coil to reduce the indoor temperature. [0003] When the air conditioner cools down, the temperature of the coil is relatively low, and the indoor humidity will be correspondingly reduced due to condensation. In areas with dry summer climate in the north, the humidity is not high enough, and users do not want to dehumidify. Feel extra comfortable. In addition, in the humid areas in the south in summer, the humidity is too high, and the user wants to cool and dehumidify at the same time. Due to the unreaso...
