Embodiment 1

[0050] see figure 1 , The method for controlling the fresh air of an air conditioner provided by this embodiment includes the following steps S1, S2 and S3.

[0051] Step S1: Determine the priority of the fresh air function and the temperature control function with reference to the carbon dioxide concentration in the indoor space.

[0052] In step S1, based on the pre-detected or obtained data information of the carbon dioxide concentration in the indoor space where the air conditioner is installed, the priority of the fresh air function and the priority of the temperature control function are compared, and it is obtained that the priority of the fresh air function takes precedence over the temperature control function The priority of or the priority of the temperature control function takes precedence over the priority of the fresh air function. The temperature control function may specifically be a cooling function required when the temperature of the indoor space is high, ...

Embodiment 2

[0079] In this embodiment, different from the above-mentioned Embodiment 1, in step S3, when the priority of the temperature control function is higher than that of the fresh air function, the rate of change of the carbon dioxide concentration in the indoor space is referred to, if the carbon dioxide concentration in the indoor space is If it is increasing at a rate higher than the second set rate value, control the fresh air function to start, and the working power of the fresh air function is lower than the set power value.

[0080] During the use of the air conditioner, as the continuous use time increases, the concentration of carbon dioxide in the indoor space will increase. If the priority of the temperature control function is higher than the priority of the fresh air function as in the above embodiment 1, the fresh air If the function is not activated, the concentration of carbon dioxide in the indoor space will continue to increase until it is higher than the second se...

Embodiment 3

[0090] In this embodiment, different from the above-mentioned Embodiment 1 and Embodiment 2, if the carbon dioxide concentration in the indoor space is lower than the second set high value in step S1, it is determined that the priority of the temperature control function is higher than that of the fresh air function , then in step S3, referring to the rate of change of the carbon dioxide concentration in the indoor space, if the carbon dioxide concentration in the indoor space is increasing at a rate higher than the second set rate value, then control the fresh air function to start, and the working power of the fresh air function is low to set the power value.

[0091] When it is determined that the priority of the temperature control function is higher than that of the fresh air function because the carbon dioxide concentration in the indoor space is lower than the second set high value, the reason why the priority of the temperature control function is higher is not because ...

Abstract

The invention relates to a fresh air control method for an air conditioner and an air conditioner. The fresh air control method of the air conditioner includes: determining the priority of the fresh air function and the temperature control function with reference to the carbon dioxide concentration in the indoor space; when the priority of the fresh air function is higher than the priority of the temperature control function, referring to the carbon dioxide concentration in the indoor space. The rate of change, if the carbon dioxide concentration in the indoor space is decreasing at a rate higher than the first set rate value, the control fresh air function will not start; if the rate at which the carbon dioxide concentration in the indoor space decreases is lower than the first set rate value, Then control the fresh air function to start. The above-mentioned fresh air control method for an air conditioner and the air conditioner can more accurately determine different scenes in the indoor space, and activate the fresh air function at an appropriate time more intelligently according to different scenes.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and in particular, to a fresh air control method for an air conditioner, and an air conditioner. Background technique [0002] Air conditioners generally have cooling and heating functions, which can reduce the temperature of the indoor space when the temperature of the indoor space is high, and increase the temperature of the indoor space when the temperature of the indoor space is low. During the working process of the air conditioner, the indoor space is generally required to be kept basically sealed to achieve high cooling and heating efficiency and good cooling and heating effect. However, when the air conditioner works for a long time, the indoor space cannot be ventilated for a long time, which will cause the carbon dioxide concentration in the indoor space to rise and the oxygen concentration to drop, making the air more polluted, and easily causing the human body to produce symp...
