Air conditioning system with fire alarm function and control method thereof

Abstract

The invention discloses an air conditioning system with a fire alarm function and a control method thereof. The control method comprises the steps of S1 to S3, electrifying and starting an indoor unit, then detecting the indoor environment temperature once every one minute through a temperature detection unit, and detecting the carbon monoxide concentration once every one minute through a carbon monoxide concentration detection unit, recording the indoor environment temperature detected in the i-th minute as Ti, recording the carbon monoxide concentration detected in the i-th minute as Ci, obtaining the indoor carbon monoxide concentration change rate beta i in the i-th minute through calculation, and obtaining the indoor environment temperature real-time change rate theta i in the i-th minute through calculation. Whether smoldering fire is generated or not is judged according to the carbon monoxide concentration change rate and the carbon monoxide concentration condition, the phenomenon that an alarm is triggered by too heavy water vapor, too heavy moisture or smoke generated by cigarettes to give a false alarm is avoided, and judgment on fire disasters can be more accurate.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to an air conditioning system with a fire alarm function and a control method thereof. Background technique [0002] Among various disasters, fire is the most frequent and common. Generally, family fires are caused by people's negligence to fire hazards, which are often caught off guard. Moreover, fires can directly or indirectly cause property losses, and even casualties. For the monitoring and alarming of home fires, at present, the most common monitoring and alarming equipment is a smoke alarm, which monitors the smoke generated by a fire through a sensor to judge the occurrence of a fire. Among them, the sensors used in smoke alarms include ion sensors and photoelectric sensors. Because the photoelectric sensor is easy to be triggered and sensed in an environment with too much water vapor and humidity, and the ion sensor is also easily triggered to sense the s...

AI Technical Summary

Problems solved by technology

Because the photoelectric sensor is easy to be triggered in the environment with too much water vapor and humidity, and the ion sensor is also easy to trigger the smoke generated by the cigarette, so that the smoke alarm is easy to misjudge the occurrence of the fire.
