A control method of air conditioning system with fire alarm function

Abstract

A control method of an air-conditioning system with a fire alarm function, the control method includes steps S1 to S3, the indoor unit is powered on and turned on, and then the indoor ambient temperature is detected by the temperature detection unit every 1 minute, through The carbon monoxide concentration detection unit detects the carbon monoxide concentration every 1 minute, wherein, record the indoor ambient temperature detected in the i-th minute as Ti, record the detected carbon monoxide concentration in the i-th minute as Ci, and then obtain the i-th minute by calculation The indoor carbon monoxide concentration change rate βi at time, and the real-time change rate θi of the indoor ambient temperature at the i-th minute is obtained by calculation; whether there is a smoldering fire is judged by the carbon monoxide concentration change rate and the carbon monoxide concentration, and water vapor is avoided , Humidity is too heavy or smoke generated by cigarettes triggers the false alarm phenomenon, which can judge the occurrence of fire more accurately.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to a control method for an air conditioning system with a fire alarm function. 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 smoke gen...

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.
