The invention discloses an automatic carbon dioxide fire extinguishing system and relates to a fire extinguishing system. The system comprises a plurality of independent unit systems, wherein each unit takes charge of a corresponding protective zone; carbon dioxide storage bottles are suspended on a fire extinguishing agent bottle group bracket; each carbon dioxide storage bottle is connected with a collecting pipe through a high-pressure hose; selector valves for combining distribution systems are arranged between the collecting pipe and a master pipeline; each selector valve corresponds to one protective zone; a fire extinguishing agent delivery pipe extends into a fire protection zone; a nozzle is arranged at the tail end; a fire detector is arranged inside each protective zone; a start steel cylinder is connected with each carbon dioxide storage bottle through a start pipeline. The system is efficient and reliable automatic fire extinguishing equipment, can automatically detect a fire, automatically alarm and automatically put out a fire, comprises three operation modes (full-automatic start, manual start and mechanical emergency start), adopts the carbon dioxide as the fire extinguishing agent, does not contaminate articles, is simple to clean after a fire disaster, good in insulativity, low in cost, convenient to install, reliable in performance, efficient and timely.

The invention discloses a control method and device and an air conditioner. The method comprises the steps of conducting detection on the operation condition of electrical equipment through an alarm detector; and when the abnormal condition is detected through the alarm detector, controlling the abnormal condition. According to the control method and device and the air conditioner, a refrigerant concentration detector, a fire detector, a small fan and a fire extinguishing device containing carbon dioxide are arranged on an indoor unit, so that the electrical equipment adopting combustible type refrigerant is protected; fire danger is avoided to the greatest extent; the mass of the refrigerant of the indoor unit is reduced; the requisite condition for combustion explosion after the refrigerant leaks is eliminated; and safety of users is guaranteed to the utmost extent.

The invention discloses an accurate fire extinguishing system for large oil filling equipment used in a substation. The accurate fire extinguishing system comprises a fire protection center control management system and a transformer, wherein the fire protection center control management system is connected with a control module and a plurality of transmission equipment boxes, the transmission equipment boxes are connected with intelligent foam automatic fire extinguishing systems and multispectral temperature-sensing flame-sensing composite image type fire detectors, and the intelligent foamautomatic fire extinguishing systems are connected with foam tank systems; and each intelligent foam automatic fire extinguishing system comprises a first mounting base which is in a C shape, and a first motor is installed at one end of each first mounting base. The accurate fire extinguishing system can monitor the transformer in all directions and confirm a fire disaster twice to prevent misoperation, at the same time, the dangerous areas of the transformer are numbered, the highly targeted purpose is realized, a fire monitor is conveniently and quickly adjusted to the specified preset position for fire extinguishing when the fire disaster happens, operation is safe and reliable, and the accurate fire extinguishing system has good application prospects.

The invention relates to an extinguishing nozzle of a fire extinguishing installation for selectively identifying and fighting fires in at least one protected area, and to an associated fire extinguishing installation and to a method for operating an extinguishing nozzle. The extinguishing nozzle comprises i) a communication unit which is configured for communicating with a fire detector and/or extinguishing control station of the fire extinguishing installation, ii) a control element which is configured for controlling the extinguishing nozzle, wherein the extinguishing nozzle is connectable to at least one fluid line and the control element is configured for selectively enabling and/or shutting off a passage of an extinguishing fluid, which is flowing in the fluid line, through the extinguishing nozzle, and iii) an energy harvester which is configured for providing energy for at least the communication unit and the control element by means of energy harvesting.
