Example Embodiment

[0033] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Such as figure 1 with figure 2 As shown, the present invention provides a fresh air system control method for an air conditioner. The fresh air system control method includes the following steps:

[0035] Step S1: Obtain indoor carbon dioxide concentration;

[0036] A carbon dioxide concentration sensor is installed on the indoor unit side to detect the indoor carbon dioxide concentration and judge the indoor air quality based on the indoor carbon dioxide content.

[0037] Specifically, the indoor carbon dioxide concentration P is obtained when the air conditioner is in the working state. When the carbon dioxide concentration is high, it indicates that the indoor air is not fresh, and fresh air needs to be introduced to reduce ...

Abstract

The invention provides a ventilation system control method and device and an air conditioner. The method comprises the steps that the indoor carbon dioxide concentration is obtained; a ventilation unit is controlled to be started according to the indoor carbon dioxide concentration, and fresh air is introduced an indoor; after the ventilation is started, the ventilation unit is controlled to be closed according to the indoor carbon dioxide concentration and the carbon dioxide concentration change trend; and the carbon dioxide concentration change trend is obtained by detecting a first-order derivative f (x) of the carbon dioxide concentration. By arranging a carbon dioxide concentration sensor and the ventilation unit, the indoor carbon dioxide concentration is detected in real time, the first-order derivative of the carbon dioxide concentration is accurately calculated, the indoor carbon dioxide concentration change can be accurately and reliably fed back in real time, the ventilationunit is accurately regulated and controlled to introduce outdoor fresh air into the indoor, and the ventilation unit is controlled to be opened and closed; erroneous judgment caused by abnormal signals is avoided, the data accuracy and stability are effectively guaranteed, and the indoor air quality is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a fresh air system control method, device and air conditioner. Background technique [0002] As people become more and more comfortable with air conditioners, they not only pay attention to temperature and humidity, but also pay attention to the air quality in the room, such as PM2.5, air turbidity, carbon dioxide concentration, etc. The density of carbon dioxide is higher than that of air. When there is less carbon dioxide There is no harm to the human body, but when it exceeds a certain amount, it will affect the breathing of people (and other organisms as well), because the concentration of carbonic acid in the blood increases, the acidity increases, and acidosis occurs. When the volume fraction of carbon dioxide in the air is 1%, you will feel shortness of breath, dizziness, and heart palpitations; when it is 4%-5%, you will feel dizzy; Therefore, the comfor...
