Problems solved by technology

If the human body stays in a confined space for a long time, due to the poor air flow in the confined space, it is easy to cause the concentration of carbon dioxide to be too high, causing the human body to feel uncomfortable
[0004] The existing fresh air control method starts or stops the fresh air simply based on the VOC concentration or the high or low carbon dioxide concentration. Although it ca

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] See figure 1 , which is a flow chart of an embodiment of the fresh air control method based on the present invention.

[0035] Such as figure 1 As shown, the fresh air control of this embodiment includes the following steps:

[0036] Step 11: Obtain the real-time indoor VOC concentration and the real-time indoor carbon dioxide concentration, and compare them with the VOC setting exceeding the standard condition and the carbon dioxide setting exceeding the standard condition respectively.

[0037] The real-time indoor VOC concentration and the real-time indoor carbon dioxide concentration can be obtained through the VOC concentration detection device and the carbon dioxide concentration detection device arranged in the room respectively, fo...

Abstract

The invention discloses a fresh air exchange control method. The method comprises the steps that the real-time indoor VOC concentration and the real-time indoor carbon dioxide concentration are obtained and compared with VOC set standard-exceeding conditions and carbon dioxide set standard-exceeding conditions; if the real-time indoor VOC concentration meets the VOC set standard-exceeding conditions, fresh air exchange is started; and if the real-time indoor VOC concentration does not meet the VOC set standard-exceeding conditions, however, the real-time indoor carbon dioxide concentration meets the carbon dioxide set standard-exceeding conditions, fresh air exchange is started when real-time outdoor air quality indexes meet outdoor air quality set conditions and real-time outdoor environment temperature meets outdoor environment temperature set conditions. By applying the fresh air exchange control method, indoor air quality and temperature can be both considered, and indoor environment comfort is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a fresh air control method. Background technique [0002] It is well known that VOCs (Volatile Organic Compounds) have a huge impact on human health. When the VOC in the room reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short time. decline and other serious consequences. [0003] The density of carbon dioxide is higher than that of air. When the amount of carbon dioxide is low, it is harmless to the human body. However, when it exceeds a certain amount, it will affect the breathing of the human body. If it is light, it will cause difficulty in breathing, dizziness and nausea, and if it is severe, it will cause people to suffocate and die. If the human body stays in a confined space for a long time, due to the poor air flow in the confined space, it is easy to cause the concentration of carbon dioxide to be...
