Embodiment 1

[0051] refer to figure 1 and figure 2 , the control method of the fresh air conditioner of the present invention will be described. in, figure 1 It is a flow chart of the control method of the fresh air conditioner according to the first embodiment of the present invention, figure 2 It is a logic diagram of the control method of the fresh air air conditioner according to the first embodiment of the present invention.

[0052] like figure 1 As shown in the figure, in order to solve the problem that the existing existing fresh air air conditioner cannot independently adjust the carbon dioxide concentration in a shutdown state, the fresh air air conditioner of the present invention includes a fresh air system and an air conditioning system, the fresh air system includes a blower, and the air conditioning system includes a compressor and an air conditioning system. Indoor heat exchanger. The blower may be an axial flow fan configured in the fresh air duct of the fresh air s...

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 fresh air air conditioner according to the second embodiment of the present invention.

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

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

[0089] The preset power-on time in this embodiment may be a power-on time actively set by a user, or may be a power-on time based on statistics of historical power-on times of the fresh 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 fresh air conditioner such as the compressor frequency and the 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 fresh air conditioner according to the third embodiment of the present invention.

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

Abstract

The invention belongs to the field of air conditioners, and specifically provides a control method of a fresh air air conditioner. The invention aims to solve the problem that the fresh air air conditioner cannot independently adjust the carbon dioxide concentration in the shutdown state. The control method of the invention is as follows: obtaining the preset starting time of the fresh air air conditioner and the outdoor ambient temperature, determining the air conditioning time, and determining the advance opening time, When the advance opening time is reached, the indoor carbon dioxide concentration P is detected 1 and indoor heat exchanger coil temperature T a ; Determine the carbon dioxide concentration P 1 with the preset concentration P a size and coil temperature T a with the first set temperature T 1 size; when P 1 ≥P a and T a <T 1 When the blower is controlled to rotate at the first set speed V 1 run, and control the compressor at the first heating frequency f 1 run. By controlling the carbon dioxide concentration adjustment of the fresh air air conditioner, the problem that the fresh air air conditioner cannot complete the adjustment of the carbon dioxide concentration in the shutdown state is solved, and the early opening 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 a fresh air air conditioner. Background technique [0002] In a closed room, the carbon dioxide concentration is often high, which makes the human body feel chest tightness. Usually, the suitable carbon dioxide concentration for the human body is 500PPM. At this time, people can feel comfortable breathing. If the carbon dioxide concentration is higher than 700PPM, will make people feel chest tightness, in the long run, it will cause irreversible damage to the human body. [0003] The fresh air conditioner with fresh air function has been used by more and more users. Usually, the user will turn on the fresh air system and air conditioning system after returning home from get off work. However, due to the long-term closure of the room, the indoor carbon dioxide concentration may be high. , causing the user to feel chest tightness after returnin...
