Problems solved by technology

[0003] Due to the relatively closed indoor environment, carbon monoxide gas will be produced by insufficient combustion of gas, etc., because this gas is colorless, odorless, difficult to detect, and it will cause carbon monoxide poisoning to the human body, causing harm to the human body. However, the existing central air-conditioning systems generally do not have carbon monoxide gas. detection function
