Embodiment 1

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

[0052] Such as figure 1 As shown, in order to solve the problem that the existing fresh air conditioner cannot independently complete the PM2.5 concentration adjustment in the shutdown state, the fresh 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. machine and indoor heat exchanger. Wherein, the air blower can be an axial flow fan arranged in the fresh air duct of the fresh air syste...

Embodiment 2

[0085] 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.

[0086] see image 3 ,in, image 3 It is a flowchart of the purification control method of the fresh air air conditioner according to the second embodiment of the present invention.

[0087] Such as image 3 As shown, in a preferred embodiment, the purification control method of the fresh air air conditioner also includes:

[0088] S110. Obtain the preset start-up time and outdoor ambient temperature of the fresh air conditioner.

[0089] 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 ...

Embodiment 3

[0107] 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.

[0108] Specific examples see Figure 4 ,in, Figure 4 It is a flow chart of the fresh air air conditioner purification control method according to the third embodiment of the present invention.

[0109] Such as Figure 4 As shown...

Abstract

The invention belongs to the field of air conditioners and particularly provides a purification control method of a fresh air conditioner. In order to solve the problem that the fresh air conditioneris incapable of automatically completing PM2.5 concentration adjustment in a shutdown state, the control method comprises the steps that a preset startup moment and an outdoor environment temperatureof the fresh air conditioner are obtained, air conditioning time is determined, an early starting moment is determined, and when the early starting moment is reached, indoor PM2.5 concentration P1 andan indoor heat exchanger coil pipe temperature Ta are detected; the PM2.5 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 a first set rotating speed V1, and a compressor is controlled to operate at first heating frequency f1. The PM2.5 concentration adjustment of the fresh air conditioner is controlled, so that the problem that the PM2.5 concentration adjustment of the freshair 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 purification control method for fresh air air conditioners. Background technique [0002] In a room with a relatively closed environment, there is often a high concentration of PM2.5, which makes the human body feel uncomfortable. The lower the concentration of PM2.5, the more comfortable breathing is. If the concentration of PM2.5 is high, it will make people feel uncomfortable in the respiratory tract. If things go on like this, it will cause irreversible damage to the human body. [0003] Fresh air conditioners with fresh air function have been used by more and more users. Usually, users will turn on the fresh air system and air conditioning system after returning home from get off work. However, due to long-term closed indoors, indoor PM2.5 concentrations may Higher, causing the user to feel chest tightness after returning home. [0004] Correspondingly, ...
