Embodiment 1

[0054] refer to figure 1 and figure 2 , to describe the control method of the fresh air air conditioner of the present invention. in, figure 1 It is a flow chart of the fresh air air conditioner control method in Embodiment 1 of the present invention, figure 2 It is a logic diagram of the fresh air conditioner control method according to the first embodiment of the present invention.

[0055] Such as figure 1 As shown, in order to solve the problem that the existing fresh air air conditioner cannot independently complete the adjustment of carbon dioxide concentration in the 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 conditioner. Indoor heat exchanger. Wherein, the air blower can be an axial flow fan arranged in the fresh air duct of the fresh air system, or an indoor fan of the ai...

Embodiment 2

[0088] 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.

[0089] see image 3 ,in, image 3 It is a flow chart of the fresh air air conditioner control method according to the second embodiment of the present invention.

[0090] Such as image 3 As shown, in a preferred embodiment, the control method of the fresh air air conditioner also includes:

[0091] S110. Obtain the preset start-up time and outdoor ambient temperature of the fresh air conditioner.

[0092] The preset start-up time in this embodiment may be a start-up time actively set by the user, or a start-up time calculated based on historical start-up times of the fresh air air conditioner. For example, the preset start-up time can be the start-up time set by the user through the remote control, mobile phone...

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 parameters of the fresh air conditioner such as the frequency of the compressor and the speed of the blower are properly adjusted, it can be ensured 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 fresh air air conditioner control method according to the third embodiment of the present invention.

[0112] Such as Figure 4 As shown, in a possib...

Abstract

The invention belongs to the field of air conditioners and particularly provides a control method of a fresh air conditioner. In order to solve the problem that the fresh air conditioner is incapableof automatically completing carbon dioxide concentration adjustment in a shutdown state, the control method comprises the steps that a preset startup moment and an outdoor environment temperature of the fresh air conditioner are obtained, the preset startup moment is corrected, air conditioning time is determined, an early starting moment is determined, and when the early starting moment is reached, indoor carbon dioxide concentration P1 and an indoor heat exchanger coil temperature Ta are detected; the carbon dioxide concentration P1 is compared with preset concentration Pa as well as the coil pipe temperature Ta is compared with a first set temperature T1; and when the P1 is larger than or equal to the Pa and the Ta is smaller than the T1, an air feeder is controlled to operate at the first set rotating speed V1, and a compressor is controlled to operate at the first heating frequency f1. The carbon dioxide concentration adjustment of the fresh air conditioner is controlled, so thatthe problem that the carbon dioxide concentration adjustment of the fresh air conditioner cannot be completed in the shutdown state is solved, and the early starting moment is enabled to be more accurate.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a control method for a fresh air conditioner. Background technique [0002] In a room with a relatively closed environment, there will often be a high concentration of carbon dioxide, which makes the human body feel chest tightness. Usually, the suitable concentration of carbon dioxide for the human body is 500PPM. At this time, people can feel comfortable breathing. If the concentration of carbon dioxide is higher than 700PPM will make people feel chest tightness, and if things go on like this, it will cause irreversible damage to the human body. [0003] The fresh air conditioner with the fresh air function has been used by more and more users. Usually, the user will turn on the fresh air system and the air conditioning system after returning home from get off work. However, due to the long-term closed indoors, the indoor carbon dioxide concentration may be hi...
